Chapter 3903 - SIBLING EYE CANDY ADVENTURE

Like so many of life's stories, this one started out due to a conflagration of random and unexpected events. Event one was Mr. and Mrs. Smith's decision to reconfigure the upstairs of their home given that the kids, Dan and Amanda, had gone off to college for their final years. Mr. and Mrs. Smith had reached the conclusion that the kids' final years in college would mean that they would be moving on and moving out, welcome back on occasion for long weekends. Mr. and Mrs. Smith had discovered that having the house to themselves made for much more in the way of sexy time, and Mr. Smith's recent discovery of the joys of Viagra had led them to new heights in the sex department.

With that in mind they decided to change the overall vibe of the upstairs. The thinking, primarily by Mr. Smith, revolved around the idea of converting the two upstairs bedrooms into other uses, and converting the two bathrooms, formerly adjacent to those bedrooms, into a one big bathroom spa, which would be used primarily by Mr. Smith in the pursuit of amorously plundering Mrs. Smith at every opportunity. So they turned one bedroom into his office, the other bedroom into her office, and the bathroom into a kind of destination love nest. There was a jacuzzi perched on a ledge in one corner, a walk in shower on another corner, a steam room in the third corner, and two sinks on opposite ends of the bath. Two toilet rooms were designed with total privacy in mind, they were only accessible from each bedroom, so the bath was just for luxuriating and having lustful sex, which they did manage to do, in nearly every imaginable way and in most every corner. Like Mrs. Smith sitting atop Mr. Smith in a suds filled bath while he licked suds off her tits. Or Mr. and Mrs. Smith giving each other oily hand jobs in the shower while he kissed her tits. Or like Mr. Smith bending Mrs. Smith over the sink and plowing her while he fondled her tits. Or Mrs. Smith giving Mr. Smith an epic sweaty blow job in the steam bath, while he thought about how nice it would be to be sucking on her tits. Now would be a good time to clarify that Mrs. Smith had exceptionally nice tits.

Mr. Smith had even foreseen the wisdom of mood lighting and a stereo sound system, which was generally set on smooth jazz, though when he had Mrs. Smith bent over at the sink fondling her tits he did opt to crank some energetic heavy metal. The new bathroom quickly became known as the sex bathroom, as in "hey, what do you think about visiting the sex bathroom tonight?"

Event two was that shortly into the spring semester of 2020, not months after the completion of the sex bathroom and not near long enough for the novelty and energy of the sex bathroom to wear off, Covid shut down the college and the kids had to come back home. So Mr. and Mrs. Smith had to frantically convert the two upstairs rooms back into bedrooms and dismantle as much of the sex element of the sex bathroom, which was now to become a shared bath between siblings, much to the significant dismay of Dan and Amanda, not to speak of Mr. and Mrs. Smith. Dan and Amanda tried to make the best of it, creating a set of casual rules and rough scheduling, which led to some less than casual arguing and some more strident rules and scheduling. The most significant rule revolved around door locks, so that when one person was using the bathroom, they would lock the door adjacent to the other person's bedroom. Of course that led to Amanda and/or Dan forgetting to UNLOCK said adjacent door, which led to yelling and/or causing the locked out victim to stomp around the upstairs to get access through the guilty door-locker's room.

Event three occurred a few weeks into the sharing of the formerly sex bathroom, on a day when Amanda thought Dan was at his weekly morning tennis match, and Dan thought Amanda was at her weekly outdoor covid-safe yoga session. Unbeknownst to either, Dan's weekly tennis match had been cut short due to his playing partner's stomach issues related to last night's Mexican food and more specifically tequila, and Amanda's covid-safe yoga session had been cancelled due to the yoga teacher catching covid due to some covid-unsafe activities with her landlord, who's wife was just sharp enough to connect those two dots. All that led to Amanda being in the bathroom with the door left unlocked, and Dan barging into the bathroom like he owned the place. Which would have been ok, except that Amanda was casually dressed in what can only be described as a very revealing and very pink bra and panty set, which caused a significant processing delay for Dan, in that he was shocked and surprised to see his sister in the bathroom, was shocked and surprised to see that she was half naked, and was shocked and surprised at how good she looked in pink underwear.

Amanda, on the other hand, had a much shorter processing delay.

"What the fuck Dan!" she shouted, making a weak attempt to cover herself up from her mouth gaping brother.

"Oh shit, sorry sis," he stammered, collecting himself from his shock and surprise enough to turn away in embarrassment and stumble back out the door.

It was a five second moment, a flash of vision and circumstance, but the impact was heavy. Back in his room, Dan collected his embarrassed wits enough to realize that he was hardly at fault, that she had left the damn door unlocked and even ajar, maybe even that he had apologized too quickly, which led him to inject a verbal protestation on how unjustly he had been treated, which led to another response from his still shocked and embarrassed sister that included a few more f-bombs.

Dan chose to continue to retreat from the situation and sat back on his bed, where he spent some time trying to contain his rising indignation, some time to consider mitigating the dispute, and a lot of time thinking about the image of his sister in her underwear. It had only been a flash, but like a nude scene from a movie he kept replaying it in his head, watching her turn towards him in slow motion and her mouth coming open in shock, while his eyes slowly traversed the area from the top of her feet to her hairline, all of which involved a lot of skin. His mind couldn't help but embellish, creating even more exposed skin, even more slow motion.

Meanwhile Amanda was still red faced and half naked at the sink, angry that Dan had barged into the bathroom, angry that she had been so stupid to have not closed the door, angry that he had seen her naked. But somewhere in all of that she was flustered and for some bizarre reason aroused on some level when she thought about him looking at her half naked body. Which made her even more angry.

Now would be as good a time as any to mention an extremely important angle to this story. Dan and Amanda were two people extremely well blessed by genes. To say they were both attractive people would be a significant understatement. What they were was ridiculously hot, the kind of people that turn heads no matter where they went. Dan was just over a year older, but all of his friends would initially go catatonic when they saw her for the first time, and Amanda's friends would become blathering idiots when they laid eyes on him. They were so attractive, in fact, that it was impossible for even a sibling to ignore the fact. As siblings they weren't actually hot for each other sexually, but in terms of appearance, they had to admit that it was hard not to look, and harder not to look approvingly.

This would also be a good time to point out a few other nuances related to the hot thing. Both Dan and Amanda were extremely attractive seniors in college, where just a month ago they had been spending a lot of time in very social and often sexually charged settings with loads of other attractive college aged kids. Amanda had just started dating a strapping young soccer player with a fairly endless appetite for wanton sexual adventure, and Dan had been dating not just one but two stunning young women. One was blonde and one was brunette, and both were smoking hot and so sexually liberated that when they found out that Dan was two-timing them, they decided that was ok and scheduled themselves accordingly. They even went so far as opening up the discussion as to possibly meeting for a romantic interlude on the same night, which led to a three-way chat on how that three-way might evolve, even how certain positions might be enjoyed. For example, there was a lengthy discussion on how the blonde might be perched atop Dan's cock, while the brunette was perched atop Dan's face, and whether or not the blonde and brunette might be kissing while that was going on. Or whether the brunette might consider going down on the blonde while Dan was fucking her doggy style. Or whether the brunette might be inclined to lick on his cock while he was fucking the blonde. All of which was very, very much ok with Dan, who was near ecstatic at the prospects of enjoying his first threesome, which they did indeed actually schedule. Unfortunately they scheduled the event for the Friday night that coincided with the evacuation of campus due to Covid.

So considering that Dan and Amanda had gone from those lofty heights of social and sexual activity to the dismal depths of quarantine and sharing a bathroom with a sibling, there was a considerable amount of anxiety and sexual frustration with absolutely no direction to take it.

So it might be considered reasonable then that Amanda might have a quiver of arousal at being seen naked, and that Dan couldn't seem to get the image of his half naked sister out of his mind. The image in his head did take a bit of a beating at the family dinner when she scowled angrily at him the whole time, leading him to attempt to reconcile things later when it was just the two of them.

"Hey, I'm sorry about what happened earlier, if I could do something to fix things I would," he said.

This didn't ease the glare he got from her. "Well somehow you're going to have to pay for that," she scowled. Eventually she eased up some. "I guess you owe me a favor or something."

Dan skulked off to bed, where he stared at the ceiling for a few hours, or at least towards the ceiling, as he was primarily replaying the image of his half naked sister standing at the sink. Eventually his half asleep mind started playing tricks on him, and instead of just standing at the sink, she turned and slowly walked towards him, smiling and welcoming his adoring gaze. At some point his mind wandered to ways he could further apologize for the event, and he was replaying in his head how she had suggested that he would have to owe her a favor or something. At some point deep in the night he came up with a bizarre and risky way to even the score.

Which is why, at 9 am the next morning, when Amanda walked through the unlocked and unclosed door into the bathroom during her pre-determined time slot, Dan was standing by his sink, dressed in the pink bra and panty set that he had fished out of the dirty clothes hamper.

Amanda went through the expected trifecta of reactions, shock, surprise and then...giggling.

Dan took a moment to stop brushing his teeth. "I figure thish was the fastesh way to get even," he mumbled through a mouthful of toothpaste. He spit to clear his mouth. "I saw you in this get up, so now you get to see me in it."

Amanda had moved from a blushing snicker to a hysterical giggle, one hand over her mouth trying to contain herself. Her brother had indeed rapidly evened the score in a most hilarious fashion, and she had to admit he had knocked it out of the park. She wasn't even that angry that he was badly stretching out what used to be her favorite set of underwear. Seeing a bra on a man was nothing but slapstick comedy, but the little pink panties...well that was slapstick comedy too, but she had to admit that there was definitely something sexy about the material stretched out over his bulging manhood and barely containing his shapely ass. She was laughing, but she was also enjoying the view.

"I will have to hand it to your brother, you have clearly found a way to even the score," she smirked. "And I have to admit my undies look kinda good on you."

Dan chuckled and did a short but enthusiastic dance with his hands above his head. He turned slowly in a full circle, giving Amanda a good view. When he initially came up with the idea for a payback, he thought it was a pretty funny idea, but now that he was on display in front of her and she was hooting and hollering, it had suddenly become something else. Something had clicked in his head, that being on exhibition like this in front of someone, even his sister, was damn sexy. He also suddenly became aware that being on display like this was making him aroused, and as he became aroused his cock was rubbing on the silky material of the panties and making him even harder. Realizing that there was no way that the tight silky material of his sister's panties was going to win the battle over his rapidly growing cock, and not wanting to rip through the panties and go full nude on his sister, he gave an exaggerated bow as Amanda clapped and he made his exit back into his room, closing the bathroom door. Then he opened the bathroom door again, locked it, and grinned at Amanda, who laughed and cheered some more.

After Dan was alone in his room he realized that his heart was beating fast and his stomach had butterflies. Being on display in front of his sister had created some unexpected results, not the least of which was that his cock had become fully engorged and was straining to get free of his sister's little panties. He reached down and stroked his cock a few times through the silk material and he couldn't believe how aroused he was. He lay back on the bed, replaying the recent moments in the bathroom, thinking about his sister looking at him half naked. He slipped the panties off and in a move that felt both terrible and uncontrollable, he wrapped the panties around his cock and began to slowly jack himself off, though it didn't take long at all before he exploded in a powerful orgasm, after which he immediately felt guilty. Not guilty enough to not make plans to do that again, but a little guilty.

Meanwhile, Amanda was still flushed and bothered in the bathroom. Flushed by the recent show put on by her brother, and bothered by the fact that it had actually gotten her a bit worked up. She was also pretty sure that just before Dan had made his exit he was clearly starting to get aroused, she could see the growing outline pushing against the material of her panties. For a moment she tried to imagine what he would look like without the panties, before blushing again and chastising herself for such taboo thoughts.

It wasn't until later in the day that the two of them had any more interaction, Amanda was watching tv in the living room when Dan walked in with a big grin.

"Hey I've decided to hang on to those underwear," he said. "I think I made some unexpected discoveries about myself this morning."

Amanda laughed. "Get your own drag wear brother, I am not giving up my favorite underwear for your experiments. Though I will have to admit that you didn't look terrible in that color."

"Ok, ok, I will give them back...tomorrow," he grinned.

"Tomorrow?" she said. "I'm a little worried they might be too stretched out by then."

The words had barely gotten out of her mouth before she realized the implications of the words "stretched out" and she immediately blushed. She didn't know if he knew that she had noticed, but her blush likely gave her away.

Dan laughed nervously as well, wondering if she had indeed noticed the growing bulge that had indeed probably stretched out her panties. He also had a flashback to a vision of him wrapping those same panties around his cock and stroking himself off, and he imagined her putting those same panties back on soon. He also made a decision that he would defile those panties once again before giving them back.

"Well, at any rate, bravo on your clever idea for payback," she said. "I think that was a fair compensation."

"Was it though?" said Dan with a grin. "To be honest I think it was well beyond fair. I mean, I got like a two second look at you, you got to see me in your underwear for a good five minutes."

"Was it really five minutes?" she giggled. "It seemed like it was over quick."

"It was at least five minutes, plus I did a dance," he replied. "I think I went above and beyond!"

"Well I guess I'll just have to pay it back somehow," she said, and once again immediately questioned what in the world she was saying, while also wondering what in the world she was thinking, which was that perhaps getting half naked again in front of her brother as a payback might be a reasonable thought.

And yet that wholly unreasonable thought kept her up that night, tossing and turning, half of her mind focused on the idea of parading around half naked in front of her brother, the other half of her mind wondering if she had completely lost her mind. She realized at some point in the night that her hand had impulsively drifted down between her legs and she was stroking her panties as she visualized herself on display. It had been way too long since she had enjoyed sex, she told herself.

Over in Dan's bed, a similar scene was taking place, as Dan tossed and turned and thought about the potential for having another shot at seeing his very hot sister half naked, this time for longer than a flash. It was wrong to think about it, but it was all he had to think about.

Now would be a good time for an update on how badly Dan and Amanda's potentially other sexual distractions were going. For Amanda, her soccer player boyfriend had been less and less interested in virtual sex via zoom, and in recent days had completely ghosted her, leading her to wonder if he had other options. He did. Ironically enough, her soccer player boyfriend had rekindled a playful but fulfilling relationship with his own sister. Back in high school, they had started something called "Massage Club" which started out as a remedy for sore muscles but advanced into some other territories. Massage Club had been on hiatus, but with the quarantine it was back. (For the backstory on the Massage Club, visit the three part series by this same author).

Dan's sex distractions had also taken a devastating turn. As you may recall he was days from having his first threesome with his blonde and brunette college girlfriends, who had set a date and even planned some potential activities for the group to enjoy. But then Covid closed down the school and ended that party. The three of them did continue to text about the potential for the threesome, with many a lurid detail about some of the many different ways the three of them might spend an afternoon naked. Those discussions had waned though, at least for Dan, because as it turned out the blonde girlfriend and the brunette girlfriend started texting more as a twosome, and talking more about what they might do to one another during the three way encounter, which gravitated to what they might do to one another were Dan to not be in attendance at all, which eventually evolved to just a full on lesbian sex discussion. As fate would have it, while the blonde girlfriend and the brunette girlfriend lived 6 hours away from Dan, they only lived 20 minutes apart from each other, and given they didn't have much else to do, they ended up doing each other. A lot. What they discovered is that it was actually quite a bit more enjoyable to have a girl's mouth on your clit, because they are a bit more adept at the geography than a college boy, and they also discovered that they kinda liked the sensation of giving that pleasure, which led them to the eventual discovery that going down on each other in the 69 position was like eating cake and pie at the same time, at which point they discovered that there really wasn't a reason for a third in the threesome. Which left Dan out cold.Given their lack of other sexual distractions it was fairly understandable that both Dan and Amanda put in a fair amount of time thinking about the notion of Amanda "paying back" for the lengthy opportunity to see her brother half naked in a rather fetching bra and panty set, as compared to Dan seeing her half naked in a more limited time frame. Amanda wasn't inclined toward letting her brother look at her half naked for any length of time, but she was also somehow thrilled at the notion of being on display. Dan was definitely thinking about the chance to see his sister half naked again, and he too was also remembering how erotic it was to be on display.

So it was a mixture of excitement and fear for Dan when he heard Amanda go into the bathroom the next morning. To his excitement, not only did she not lock the door on his side, she actually left it slightly open. Wary of getting yelled at for barging in, he knocked softly on the door. There was a long moment of silence, and then Amanda called out "Come in."

Dan held his breath as he pushed the door open and stepped into the bathroom, not sure what to expect. He had hoped that his sister would be half naked, like before, but to his disappointment she was wearing a bathrobe. Suddenly he realized how awkward he looked.

"Morning sis," he said blushing. "I was just coming to, uh, brush my teeth real quick."

Amanda grinned at him as he fumbled with the toothpaste. "Yeah right," she said. "You came in here expecting another show, didn't you?"

"Um, no, uh, I guess maybe, I was thinking that you had sort of said that, uh, you were gonna pay me back, like giving me a longer show like I gave you. I guess."

Amanda was smirking at him as he delivered the word salad of gibberish. "So your pervy ass would really want to see me again in my bra and panties, huh?"

Dan's high hopes were falling into the wayside of despair and humiliation as he shrugged and lamely attempted to brush his teeth. Amanda continued to smirk at him derisively for a few more quiet moments, and then she casually shrugged the bathrobe off as if it was no big deal, and she was standing six feet away from Dan dressed in a lacy black bra and panty set that may have been more sexy than the original but was certainly sexy enough to cause Dan to freeze, with his hand on his toothbrush, his toothbrush in his mouth, and toothpaste dribbling down his chin.

"Five minutes perv," she grinned. "Then you get out."

As Dan tried to remember how to breathe, Amanda just continued to go through her morning routine as if nothing was different. Dan's eyes never left her as she brushed her hair, washed her face, put on her makeup. Her body was beyond fantastic, it was like he was watching a Victoria Secret model waltzing around in front of him. Luckily he was wearing shorts that blocked his rock hard cock.

Amanda, meanwhile, was having her own heart flutterings, as Dan's attentive gaze had her realizing that she really enjoyed being an exhibitionist. She knew just how to walk, and turn, and stand, and bend over, and she could tell when she hit a hot pose -- Dan's mouth would fall open even further.

Eventually Amanda declared that his five minutes were up, that the show was over and he had to get out of the bathroom. Dan staggered out and fell onto his bed, his mind reeling with the images of his very hot, half naked sister. His cock was still burning, and he was about to reach down and grab himself when the bathroom door opened and Amanda stuck her head around it.

"Hey, so tomorrow I don't want to be the only one half naked, I expect you to wear these," she said, tossing him the black panties that she had just been wearing. "I won't make you wear the bra."

Dan briefly thought about the fact that Amanda was likely naked on the other side of the door, briefly thought about what that might look like, briefly considered how he was going to fit his crew into the lacy black panties and briefly jerked off using the black panties both mental and physical stimulation. He had to admit that he liked the feeling of the silk panties on his cock more than the lace, but it was hard to complain.

The next morning Dan woke up eager and excited about his five minute visual playdate with his sister, but his cock woke up even more eager. He immediately realized that fitting himself into the lacy black panties was going to be a challenge, but it was pretty inevitable that he was going to be experiencing a significant, likely full on erection within the five minute visual, and that the lacy black panties would not contain that on any level. So he did what any virile young man would do, he jerked off again. And of course he used the panties, in case you were wondering.

So when he donned the lacy black panties he had a nice post orgasm bulge, but it was reasonably well contained. He looked at himself in the mirror before entering the bathroom and he had to admit, he didn't hate how he looked in lacy black panties.

He gave a cursory knock on the door and walked in, his heart beating rapidly from both being on display and being excited about what Amanda would be wearing. She was back in the silk today, a bright red version that immediately had Dan thinking about how they would feel on his cock later. He nodded a greeting as Amanda somehow looked impressed and amused at the same time as she checked him out.

"Not bad bro," she grinned. "I can't believe how good you look in panties."

He blushed. "I can't believe how good these feel on me. May have to change out all my underwear."

They went through the motions, pretending to be doing the usual things in the bathroom, when most of their efforts were stealing lingering glances at the other person's half naked body. But at some point they quit trying to pretend, and just stopped doing anything but looking at each other. They stood in the bathroom, five feet apart, and just admired each other's bodies. It wasn't really sexual, it was more like enjoying eye candy. Watching sports highlights. Looking at most of the internet.

While it wasn't exactly sexual, it wasn't exactly non-arousing either, and Dan determined that even though he had made the sacrifice of jerking one out just prior to the show, he was rapidly feeling his cock harden, and realizing that it was not going to be good for the panties. Luckily for him, and the panties, a bell sounded, and Dan realized that Amanda had set up an egg timer on the counter and the the five minutes had passed. She grinned and shooed him out the door.

He collapsed on his bed and closed his eyes, trying to hold the visual of his hot sister standing half naked, her eyes looking admirably at his body. It wasn't long before he was stroking his cock through the black lace of the panties.

Later in the day he found the red silk panties and a black silk robe on his bed, with a note saying "for tomorrow." Turns out that Amanda was spending quite a bit of time thinking about the five minute eye candy sessions and had come up with a way to add some wow factor to the revelation of their half nakedness. So when Dan showed up in the bathroom the next day, wearing the hopelessly stretched red silk panties and black robe, Amanda was also wearing a black silk robe. As she turned to face him, he didn't have to think too much to figure it out. With a flourish, she untied the robe and let it fall open, to dramatically reveal that morning's outfit, which, befitting the reveal, was by far the best to date. She was wearing a one piece light purple lingerie, with lace at the top that mostly covered her breasts, and silk at the bottom that was cut high in the front and hung down at knee level in the back. It was stunning, and she was stunning in it.

"I thought you might be getting tired of the same old panty thing," she said. "I wanted your opinion on this little thing I picked up yesterday."

Dan swallowed hard. "Yes," he said. "My opinion is yes."

She grinned, enjoying the effect she was having on him. "So now it's your turn."

It took a moment for Dan to realize what she meant, what with him being dramatically distracted, but eventually he realized that it was his turn to lose the robe. He untied the clasp and let it fall open, revealing him wearing his sister's red panties, which despite being used to jerk off in just prior, were already showing signs of being stretched.

Amanda nodded her approval, taking special note of the outline of his cock, and she set the timer for five minutes. This time they didn't really pretend to be doing anything else, they just stood their and gawked at each other, occasionally mumbling compliments. Again, it was very much about enjoying the visual spectacle, rather than being sexually attraction. Dan noted the curves of Amanda's breasts under the lacy material, he wasn't sure but he thought her nipples were showing through. And her legs looked fantastic under the silky material of the lingerie. Amanda meanwhile was focused on how nice Dan's fit abdomen trailed down to the top of the red panties, and how they were resting so low on him that she could just see the top of his pubic hairs. When he turned around his ass looked magnificent in the tight panties.

Eventually the timer went off, and the two went their separate ways, to spend the rest of the day thinking about the next morning. Over the course of the next several days, they fell into a consistent pattern, and it became more normal, almost routine. They would meet in the bathroom, remove their bathrobes in the big daily reveal, gawk at each other for five minutes, and then it was over. Dan had developed a pattern of jerking off just before and just after the morning viewing, and occasionally a third time when Amanda's outfit warranted it. He had never masturbated so much in his life. He wasn't alone in that, Amanda had also found herself masturbating way more often, frequently while imagining the visual of her half naked brother. She had purchased a very realistic looking dildo at the beginning of quarantine, and she had developed a habit of looking at it and wondering how it compared to Dan. She had even started mentally calling her dildo Danny, even though that made her feel pretty weird.

After a week of five minute gawking sessions, Dan and Amanda had become pretty casual about the whole thing. It was always a bit of a thrill when the robes were cast aside and Dan could see what sexy outfit Amanda had chosen to torture him with, and Amanda could see how ridiculously funny but sexy Dan looked in the outfit she had worn the previous day. Occasionally one of them would point out how crazy it was that they were parading around in front of each other, but they both justified it by pointing out that they were dressed in about the same amount of clothes as they would wear in front of each other on the beach or at the pool.

"I've actually seen you wear less on the beach," Dan said. He was currently wearing a pair of satin boxer shorts with high cut slits up the side, which Amanda had looked so fantastic in the previous day that he had jerked off with them three times. "It's just like beach wear, it's not like we're getting naked in front of each other."

Amanda looked at herself in the mirror. Today's outfit was a leopard print tank top with tight fitting boys shorts that rode up a little high on her ass. They looked great on her, but she had gotten them because she thought they would look good on Dan. "Well I don't know that I would wear this on the beach," she said. "And I know that you would not wear those on the beach. But you're right, it is not really any more revealing. Like you said, it's not like we're getting naked in front of each other, neither one of us wants that right?"

There was a moment of silence, a lack of response from Dan, that hung in the air for several moments.

"Um, neither of us wants THAT, right?" Amanda repeated.

The way Dan heard it, she wasn't really saying it as an ultimatum, it was more like she was putting it out there as a point for discussion. Or maybe that was the way Dan wanted to hear it.

"I mean, well, I guess that it wouldn't really bother me, I mean, I wouldn't have any problem being naked in front of you, it's just a visual show, it's not like it's something sexual or anything," he said.

Amanda crossed her arms and leaned into one hip, looking at him like he was a pervert. "So you would really want to see ME naked?" she said.

All Dan could think was that even with her arms folder across her chest and her looking at him like he was a pervert, she was still dead sexy. "Well, I mean, damn girl, you're super model hot, even if you are my sister I'd be crazy not to want to see that," he said.

Amanda rolled her eyes and turned back to the mirror to fiddle with something on her sink. Dan had recently been looked at like he was a pervert, but he couldn't help but gawk at the curve of her ass showing from the bottom of her panties.

Just then the timer went off, and Dan regrettably had to peel his eyes off his sister's ass curve. He slunk back into his room and went straight for the bed, laying back in the satin boxer shorts and closing his eyes to remember the visual of his sister bent over the sink. He had just started to stroke his cock through the silky material when his sister popped her head around the corner of the bathroom door. She hesitated in surprise when she saw what he was doing, but she re-grouped quickly.

"I'll agree to getting naked together, but on two conditions," she said. "First, it has to be after the regular five minute session, because I really want to see you in leopard skin. Second, you have to do my laundry for a week."

Dan had not yet collected his mind enough yet to even take his hand off his cock, but he somehow managed to nod in agreement.

Amanda couldn't resist a parting shot. "Looks like my panties are going to need some extra washing."

Dan looked down at her panties, the satin boxers that were barely containing his cock, which was covered by his hand, which if he had his wits about him he would've removed, but he did not. Instead, he had a flood of thoughts, in no particular order.

--He was going to see his hot sister naked

--She was looking forward to seeing him in tight leopard skin

--Wait, she was going to see him naked

--Holy cow, she had seen him jerking off while wearing her lingerie

--He was going to spend a lot of time with her laundry before washing it

--Tomorrow could not come soon enough!

Indeed, Dan hardly slept that night, thinking about seeing his sister fully naked. Her body was so amazing the idea of seeing all of it was overwhelming. He also spent a lot of time thinking about being naked in front of her, it was all so exciting and taboo that sleep was impossible.

In fact, he was so excited about the day's adventure that he forgot to jack off, and didn't remember that until he was standing in the bathroom in his robe, looking at his sister in her robe, and wondering whether or not she was naked underneath the robe, and how she was going to look when that robe fell away, and how he was going to look when his robe fell away, because he definitely had a full on boner that was going to be dangerously stretching the leopard skin material of the very tight underwear he was wearing.

So there they were, six feet apart, both wearing robes, Dan wondering if she was naked underneath and Amanda with a mischievous grin on her face. Technically they were still supposed to do the usual five minute gawking session, and THEN get naked but Dan wasn't sure.

At the moment of truth, Dan slipped his robe off and Amanda...did not.

"I am just going to keep my robe on for now," she said slyly. "I will take it off after the five minutes is up."

So Dan was on display, by himself, his cock steadily getting harder at the thought of seeing his sister naked. The tight boy short style panties was doing a really good job of showing the outline of his cock, and Amanda was not making any "bones" about her attention to that detail.

"I'll have to say, I think I did a great job of picking out your look today," she said. "I may just let you have those."

Dan grinned. He had kinda stopped caring about the fact that his cock had gotten so hard it was tenting the shorts ridiculously. He figured that he was going to be completely naked soon anyway, so it hardly mattered. The five minutes finally passed, just in time to save Dan from ripping through the shorts.

"So I guess its time to get naked huh," Amanda said. She pulled the tie loose on her robe, and as Dan looked on breathlessly she let it fall open and drop away from her shoulders.

But it was not what he expected to see. Instead, Amanda was not naked, she was wrapped in a towel. "Just to clarify, we will be getting naked in front of each other in the steam room," she grinned.

The words sunk in to Dan like anchors. The steam room was big enough for two people, and those two people could be naked, but the steam would make visibility zero. So he had agreed to do a week of laundry for nothing but sitting in a fog.

Amanda walked over to the steam room and stepped inside. "I'll see you inside," she said, as she walked in and then her arm came out and dropped the towel on the floor.

Dan gave a whimper, and sulked his way over to the steam room door. He hadn't even noticed it was running, and it was pea soup inside. He went in and slipped off the shorts he was wearing and immediately started developing fantasies about a break in the steam. Or a power failure.

But the steam was thick, he could hardly see his hand in front his own face. They sat together in the steam room, just a few feet apart, fully naked, but totally invisible to each other.

"How ya doin?" Amanda said after a few silent minutes.

"Oh shut up," Dan replied, causing hysterical laughter from his sister.

"I said we'd be naked together, I didn't say anything about visibility," she laughed.

Dan eventually got over his anger at being conned and started to relax in the heavy steam. He was still just a few feet away from his completely naked and very hot sister, and it felt pretty good being naked. He suddenly realized that because she couldn't see him either, he could reach down and stroke his cock while he imagined what she looked like naked.

It wasn't long before his steamy, sweaty hands had his steamy, sweaty cock in a steamy, sweaty hard on. His mind drifted into a fantasy where suddenly the steam stopped, and his sister was standing there naked in front of him, watching him stroke his cock, while she caressed her perfect tits and licked her lips. Then she got down on her knees in front of him, and....

"What?" he heard her ask, and suddenly he realized that he had let out a very audible groan as he was imagining her taking his cock into her mouth.

"Oh, ah, nothing," he stammered.

It was silent for a moment, and then she said "Oh my god you're touching yourself aren't you?"

"Uh, well, uh, just a little bit," he managed to say, before realizing he could've made any number of other answers that would've been better.

"Geez, you can't spend five minutes in a steam bath with your sister without touching yourself," she said. "You perv."

Realizing that she was not mad and just making fun of him, Dan relaxed. "Sorry, you know men, they just can't keep their hands off themselves."

"You're all horn dogs, I bet you couldn't go one full week without touching yourself," she said.

The comment hung in the air for a moment, a moment that Dan spent formulating a new plan. "Care to make that a bet?" he asked. "If I can go one week without touching my myself, then you have to let me see you naked."

"Well that would have to be the safest bet in history," she laughed. "Are you serious?"

"I'm serious. If I can go one week without touching myself -- touching my, uh cock I should say --then I get to see you completely naked, and by see you I mean I can see you.""Hmmm. So what do I get if you fail?"

"Two more weeks of laundry duty," he said.

"I think you have a deal, one week puts us at Friday" she said, and Dan saw a hand come out of the mist.

As Dan shook her hand, she said "starting right now," and he realized, with a chill in the steam room, that he was going to have to remove his hand from his rock hard cock, a cock that was probably within a stroke or two of a very steamy, sweaty orgasm, and forgo what would have been a very satisfying release. It was at that moment he had his first sign that he was in for a long week.

He had no idea how hard it was going to be. He had become very accustom to a jerk off session after the five minute eye candy visits, and it was torture to skip that. But over the course of the day, he began to realize that he, as a virile male at the peak of his testosterone years, spent a lot of time touching himself. Or did, before he made that bet.

It was also apparent that it was not going to be remotely possible to hide his emphatic boner during the morning eye candy sessions. At some point in the middle of the boner filled night he decided he was just going to be proud about the fact, even if it meant his sister was going to know that looking at her gave him an erection. She likely knew anyway.

She did know anyway. And she was kinda looking forward to the coming seven days, because she knew he was going to be harder and harder every day, and she was kinda interested to see that bulge. She had even idly thought about the fact that when she shook his hand in the steam room, it had recently been wrapped tightly around his cock. She wasn't worried about the bet thought, she assumed that he was going to give in by mid week.

So the next few days, they continued the same pattern they had established before. They would meet in the bathroom at 8:30 am for the daily reveal, when they would open up their bathrobes. Amanda would be showcasing whatever lingerie she had chosen to torture Dan with, and Dan would be precariously stuffed into whatever Amanda had donned the day before. By Monday, Dan was getting hard if the wind blew, and Amanda, well, she was getting a little worried that Dan might pull off the full week.

On Tuesday morning Amanda showed up in a sexy French maid outfit with an impossibly high skirt and knee high nylons and she made quite a show of bringing Dan a steaming cup of coffee. Dan, in the midst of doing some serious damage to the lacy panties she had him wearing, drank down the entire cup without realizing he probably scalded his mouth.

On Wednesday Amanda showed up in a sexy school girl outfit, with another nearly ass revealing plaid skirt, the tiniest of a midriff exposing button up shirt held together by a flimsy knot, and thigh high white stockings. She once again delivered a cup of coffee to Dan, this time walking over to him with an exaggerated hip swing. She dropped a packet of sugar and made a long slow show of bending over in front of him, showing off the thinest of white thongs under the skirt. Meanwhile Dan was wearing the sexy French maid outfit, which didn't look terrible on him but did expose his balls. If his cock hadn't been sticking straight up, he would be on full display.

Dan's cock had reached a level of constant stiffness that shocked even him. It was almost weird how hard he was, he actually started to worry it might be getting too hard. Despite that, he steadfastly avoided touching himself, even though it took every ounce of concentration.

Now would be a good time to explain just why Dan's cock had reached a level of supernatural state of hardness. Amanda, having become somewhat concerned about losing the bet, had decided to ramp up the pressure on her horny brother by dosing him with some of the Viagra that their dad had accidentally left behind in the former sex bathroom. The coffee that she was so diligently serving him in the morning also had a healthy dose of the miracle erection drug.

That night Dan's cock was so hard he had to sleep on his back, and sleep did not come easily. He had one more day of no touch torture before he would get to see his sister naked, and he was not ready to give up. He had finally dozed off when he was awakened by someone's voice.

"Hey, wake up, you idiot," the voice said.

He blinked himself into consciousness and looked, and realized the voice was coming from none other than his cock, which had morphed into a full human size and was standing by the bed looking down on him. It was his cock, but six feet tall with a face and arms and legs. It didn't take him long to realize he was dreaming, but he couldn't seem to wake himself up.

"What the hell do you want?" he asked, and then blushed right after he said it.

"I think you know what I want," his cock answered. "I want this torture to be over with, I'm about to explode."

"Well you're just going to have to wait," Dan replied, feeling a little weird about talking to his cock.

"I'm tired of waiting, we need some relief" his cock said, and grabbed Dan by the arm and pulled him out of bed.

Before Dan knew it, his cock had pulled him through the bathroom and into Amanda's bedroom, and they were standing side by side by her bed. There was an odd smoky mist in the room, and he could smell Amanda's perfume in the air. When he looked down in the bed, Amanda was on her back, wearing nothing but panties, with one arm over her head and the other on her stomach. Her legs were just slightly spread, one leg straight and the other slightly bent. She was in a deep slumber, her mouth hung slightly open, her hair was shiny and full and her skin aglow. Her breasts were on full display but for some reason Dan couldn't focus on them. The scene in front of him was so erotic he felt like his head was on fire.

"I'm tired of waiting," his cock said again, and to Dan's horror, his cock climbed into bed and on top of his sister, and practically melted into her beautiful body. She murmured and stirred as the giant cock pressed into her flesh, and Dan feared she might awaken.

But her slumber continued, and his cock began to slowly move against her, carefully wriggling against her body, and Dan realized that while that his life size dream cock was a separate entity, he could feel what the cock was feeling. He was watching a full size cock gyrating against his sister's nearly naked body, and he could feel it at the same time.

Amanda was still sleeping, but her arms moved around the cock, and then her legs, so that she was wrapped around the giant, throbbing member, pulling it tight up against her. Then she groggily moaned and sighed, and then her lips pursed, and then suddenly she was kissing the giant cock, first with her lips and then her tongue, and Dan was about to pass out because he was both seeing this incredible scene and also feeling his sister's mouth and tongue bathing his cock. Now they were both moaning and writhing on the bed, Amanda was making out with the cock, and Dan could feel and orgasm welling up inside him, and then....

He woke up, alone in his bed, sweating and rock hard but just short of having an epic orgasm. He gasped and shook his head, briefly wondering if he may have been sleep walking and actually gone into his sister's room. Sleep would not return easily.

Meanwhile Amanda was having her own restless night, as she realized that she had one more day to try and win the bet by pushing Dan to give in and jerk himself off. She knew he had to be hurting, based on the daily visuals of his cock stretching out her lingerie and the Viagra load she was serving him. Her thoughts had become an odd mix though. She wanted to win the bet, but she also wanted to see him naked. Even more, she had to admit that she wanted to be naked in front of him. Over the past few weeks she had discovered that being an exhibitionist was the most exhilarating thing she had ever done, and the taboo of arousing her brother had become quite overwhelming. So her sleep was quite fitful. At one point she even had a dream she was rolling around in the bed with a giant cock.

At some point in her tossing and turning she did come up with an idea for pushing Dan over the edge that she was pretty sure was going to work.

Dan was up early preparing for the appointed hour, and he was feeling pretty confident that he would be seeing his sister naked the next day. All he had to do was survive one more shared bathroom exhibition. He did have an issue with trying to get into the school girl outfit that Amanda had worn the day before. The understanding was that he would not even try to get into the top half of her outfit, he usually ended up packing his unit into a tight pair of panties. But the school girl outfit was a barely there thong, the skirt was super short, and his cock was ridiculously hard. At some point he decided to get creative.

They showed up together wearing the usual robes, but it seemed like it was less casual and fun with the bet on the line. They stood there, five feet apart, until Amanda finally broke the tension.

"Why don't you go first today," she said. "I am so looking forward to seeing how you are going to look as a school girl."

"That's not something I ever expected to hear," Dan laughed. "To be honest, there was no way I could fit into that get up, so I kinda improvised."

He opened up his robe and Amanda gasped, and then chuckled. Dan had tied the top, the thong and the skirt into what could loosely be called a cock wrap. It kind of looked like a really badly tied bow, and the only thing it covered was his turgid cock and swollen balls.

Amanda was impressed on several levels. First, the creativity in converting the outfit was genius. Second, she had never seen this much of her brother's body, he was all but naked, and he looked fantastic. And third, there was something in the energy of Dan's body that was mesmerizing. He was so intense, his muscles were taut and he was almost glowing. She had to believe that it was the powerful buildup from not being able to touch himself for a week.

"Very nice," she smiled. She walked slowly over and handed Dan his morning coffee, which was once again loaded with Viagra, unbeknownst to him. Then she walked back over and faced him, her hand nervously holding onto the clasp of her robe.

"Your turn," he said, almost hungrily.

She smiled seductively and hesitated for effect, before she slid the robe open and in one quick motion shrugged it off and let it fall away to the floor.

Now it was Dan's turn to gasp. Amanda was wearing a simple spaghetti strap babydoll nightgown, cut low at the top showing the curve of her breasts, and just long enough to show the curve of her ass. But the most stunning thing about it was the fact that the shimmering black material that covered her gorgeous body so sparsely was also virtually see through. The shimmering quality of the material made it not completely sheer, but as she moved there would be angles where Dan could see the darker skin of her nipple, or the neatly trimmed hair down below.

Dan didn't speak, or breath, or move for several moments, his eyes just taking her in.

"I thought I'd give you a preview for tomorrow," Amanda said. She looked him up and down, her eyes resting on his barely covered groin. "If you think you can make it one more day without, you know, stroking that cock."

Dan's eyes got big. He realized that she wanted to win the bet, and if that meant she was going to have to spice up the language, she would. He had no idea.

"I wonder how you'll look in this outfit," she said. "But oh, I guess tomorrow we'll both be naked."

She walked slowly over to the sink and got something off the countertop. "Oh, look at what I left here, I forgot all about this," she said.

What she picked up was her life like dildo, the one she had bought just a few weeks ago to keep her company during the pandemic. She held it lovingly in both hands, grinning mischievously.

"It must be really, really HARD to not be able to touch yourself," she said, her fingers lightly caressing the dildo, her eyes watching it intently. "It must be TORTURE to not be able to do this."

She stroked the dildo slowly, her long elegant fingers moving up and down and softly touching the tip.

Dan whimpered. This was not fair. For the last several days, his cock had been as hard as he had ever imagined it could be. It was now getting considerably harder. And bigger. So much harder and bigger, in fact, that the school girl outfit wrapped around his cock was rapidly becoming overwhelmed. But he wasn't paying any attention to that. His eyes were on Amanda, watching her fingers on the dildo. Watching her caressing the cock. He could almost feel what those fingers would feel like.

Amanda's hands were indeed stroking the dildo, but she wasn't looking at it. She was looking at Dan, and she had reached an almost hypnotic state. His body seemed like it had come alive on another level, so powerful and rigid from his obvious arousal. And the material he had spliced together over his cock was rapidly losing the battle.

Both of them were so immersed in watching the other that they completely forgot about themselves. Dan was mesmerized watching Amanda stroking the dildo. He did not notice that the cloth covering his cock was already pulling away, and he was rapidly becoming exposed. Amanda noticed it, she was watching it closely, so closely that she lost track of what she was doing, which was moving the dildo up to her cheek, moving it across her face to her lips, and kissing it. But she wasn't thinking about the dildo, she was thinking about Dan's powerful cock, which was throbbing harder and harder as ever more of it emerged into the open.

Then the inevitable happened, what was left of the school girl outfit broke apart and fell away. Time seemed to stop, or at least go into slow motion. Amanda's mouth was practically wrapped around the dildo, but it fell open when she saw his full naked cock on display. Dan was so focused on watching Amanda he did not even realize what had happened right away, but after a few seconds he looked down and realized that his rock hard cock was on full display, and he froze, his mind was not in a place where he could immediately process what was going on.

They stood there for a full ten seconds, frozen in the moment, and then suddenly, like a bomb going off, the five minute timer dinged in and jerked them back into reality. Both of them were fully flushed with the emotion and arousal of the moment. Dan turned and stumbled out of the bathroom, went to his bed, and curled up in the fetal position, where he would remain for most of the rest of the day. Amanda was beyond flustered, first by the images of seeing her hot brother naked, and second by the fact that she looked to be on the losing end of the bet -- tomorrow she would be getting naked in front of her brother. And third, of course, that she wasn't going to get her laundry done for the next two weeks.

For those seeking a diversion at this point, now would be a good time to give an update on Mr. and Mrs. Smith, who were living downstairs entirely oblivious to all the exhibitionist and voyeuristic antics going on upstairs in their previously enjoyed sex bathroom. They were entirely oblivious because after a time period of being pretty bummed about not having their sexy time in their sexy bathroom, they had come up with an idea they called the "Seven Day Covid Sex Challenge" which was principally the idea that they would have some sort of sex every day for a week, which turned out to be so successful that they turned it into the "30 Day Covid Sex Challenge," which led them to either be busy having sex or too tired to even think about going upstairs to check on the kids. At some point during the 30 day challenge Mr. Smith had come upon an idea to enjoy his wife's very fabulous tits in an altogether new way, namely sliding his cock in between them after lubing them up with baby oil. Amazingly Mrs. Smith took to it as well, and even though Mr. Smith had misplaced his Viagra, they discovered that titty fucking was a tremendous way to pass the time, and also discovered there was quite a variety of ways to do that. Him on top, her on top, her on her knees, even in the 69 position.

Anyway, Dan and Amanda spent yet another night doing a lot more tossing and turning than sleeping. Amanda was nervous, but excited, at the idea of being fully naked in front of her brother, but she spent more time thinking about how hot Dan looked naked, and how incredible his cock looked. Dan of course was thinking about how hard his cock was all the time. When he thought about Amanda looking at his cock with her mouth slightly open, it got harder.

So at the appointed hour, the two siblings met in the sexy bathroom wearing the silky black robes, and stood just five feet apart in nervous anticipation of the unveiling.

"So I guess you won the bet, so now your pervey self gets to see me naked," Amanda said.

"Well, yeah, but more importantly I don't have to do your laundry for two weeks," Dan grinned. "But listen, if you don't want to do it, it's ok, no pressure on backing down."

Amanda considered the offer for a few moments. In truth, she was nervous, but extremely excited, about being naked and on display, and she also wanted to see Dan naked again. She just didn't want to act too eager about it.

"A bet is a bet," she smiled, and she raised her hand up to loosen the tie on the robe. Her trembling fingers released the tie and let the robe slide open, and Dan got his first look at his fully nude sister.

She was more perfect than he had even imagined, her breasts were the ideal size and shape, her pussy looked delicious and her curves were in all the right places. Dan just stood there in stoned silence, in a state of complete fascination with how hot his naked sister was. He was so spellbound, in fact, that he forgot all about his end of the bargain.

Amanda grinned. "So I guess it's your turn then," she said.

Dan looked at her blankly, so entranced with the vision in front of him that he couldn't process anything. He did eventually figure out what she was talking about, and he let his robe fall open and showcased the glorious cock that once again had Amanda gasping.

They stood there, five feet apart, staring at each other and being increasingly aroused at the idea of being ogled by the other. Amanda was getting progressively wetter, and getting a little nervous that it might be showing. Dan's arousal was clearly on display, there was no mistaking that.

At some point Amanda pointed out that she had forgotten to set the timer, but neither of them made any kind of move to end it. Finally Amanda broke the silence.

"So I guess the week is out and the bet is won...so...I suppose...you can touch yourself now," she said.

Dan nodded vigorously. "I don't know how I made it a week, it is honestly the hardest thing I've ever had to do."

Amanda giggled. "It LOOKS like the hardest thing you've ever had to do."

Dan laughed and for the first time in ten minutes he took his eyes off Amanda to look down at his engorged cock. He had been fantasizing for days about wrapping his hands around his cock and jerking himself into multiple orgasms, he had plans to masturbate for at least two straight days.

Amanda admittedly felt pretty bad about putting Dan through the week, especially with secretly dosing him with Viagra. Before she realized what she was saying, it had slipped out. "I guess you can touch it now...if you want," she said.

Dan's eyes got big and he hesitated, but the idea of being able to touch himself was too much. He reached down with one hand and gave his cock the long, slow stroke he had been thinking about for a week. He leaned his head back, closed his eyes and groaned.

Fascinated with the urgency of her brother's passion, Amanda took a tentative step closer, intently watching his cock throbbing. She was amazed and enthralled at the obvious energy boiling below the surface of her brother's naked body. She was so enthralled that she didn't realize that she was moving closer to him, her eyes focused on Dan's hand stroking his cock.

Meanwhile Dan had become somewhat enthralled himself, notably because he had been sure that after so many days of not touching himself, he would probably have an immediate orgasm. But something was different, he was rock hard, he was throbbing, but he had reached some kind of plane where he felt in complete control of his orgasm. And he was enjoying himself, and in enjoying watching his naked sister staring at his cock, way too much.

Amanda had continued her spellbound move towards Dan, and was now just a foot away, her eyes still locked on his cock. She suddenly felt dizzy, and fell to her knees right in front of him, and now she had an even better vantage point to continue watching him stroke his cock.

The room had gone from being an experimentation in exhibitionism and voyeurism to something entirely different. The room was now full of sexual urgency.

Dan was standing proud above his sister, looking down at her as he stroked his cock from base to tip, still amazed that he hadn't lost his load. She looked amazing, naked on her knees in front of him, looking at him with adoration. He thought he saw her lick her lips, and he couldn't help but wonder if she wanted him to move closer and put his cock into her mouth.

Amanda wasn't NOT thinking that, but somewhere in the back of her mind an inner voice was screaming at her to put the brakes on. But she didn't want to stop watching, and she had suddenly found an uncontrollable urge to touch herself. She moved off her knees, reclined back on the floor and moved her hand down to her wet pussy. She somehow found enough clarity to lock eyes with Dan and whisper softly, but definitively, two critical words:

"No touching."

It only took Dan a few seconds to understand what she meant. They could masturbate in front of each other, naked and close, but the boundary was no touching. He nodded and continued the slow and urgent stroking of his now shockingly hard cock.

The room was quiet, save for an occasional moan, as Dan stood massaging his cock and Amanda lay back on the floor and slowly caressed her pussy. Dan suddenly realized that he was getting dizzy, likely because all his blood had moved to his cock. He felt his legs going out from under him and he moved down to his knees, straddling one of Amanda's thighs. His hard cock was now less than a foot away from her warm, wet pussy, but they somehow still maintained the no contact rule.

Dan continued to fondle his cock as he looked down upon his naked sister. He looked almost like a hungry animal, perched above prey that he was about to devour. Amanda had a look on her face that was half fear, half lust. There was a massive battle going on in her brain, one side saying stop, this is your brother, and the other side saying she had never wanted anything more than for him to close the gap and plunge that hard cock deep into her.

Something about the look on her face, the lust/fear conflict, pushed Dan further to the edge, and he could suddenly feel a week-long orgasm building deep inside him. His moans and increased thrusting made Amanda realize what was coming, and she looked at her brother and nodded. She wanted him to come, and so did he. His hips began to gyrate, and he began to pump himself faster and more furiously, and at some point his thrashing did violate the no touch agreement as his swollen balls grazed up against Amanda's thigh.

Then he felt the inevitable explosion, and the most intense orgasm of his life took hold of his body and mind and he lost all sense of time and place for what seemed like a ten minute span, and when his mind came back to him he looked down and he was still launching his load everywhere. In a moment of abstract horror he realized that he was pouring his load all over his sister's naked body, but there was nothing he could do about what had already happened nor what was still happening.

His orgasm felt like it lasted forever, his cock just kept throbbing and spurting, eventually he felt the sensations in his cock easing up and he closed his eyes and slowly let his breathing come back to normal. When he opened his eyes and looked down, he nearly gasped in shock. His sister's naked body was just covered in a white lake, from her belly to her chest. And the look on her face suggested that she might just be a little pissed about that.

He was just about to start an effusive apology when the look on Amanda's face slowly changed from anger and disgust to something lustful and naughty. She had surrendered to the unabashed sexual urges side of her brain, and she figured if she was already covered in cum she may as well make the best of it. She playfully moved her hand down to the pool on her belly and began to spread it around, rubbing it over her beautiful tits and then down into her pussy hairs, which were soon sopping wet with her brother's load. She felt dirty and scandalous, and deliciously sexy. She could see the effect she was having on her brother, who was wide eyed with fascination and amazingly, instantly becoming aroused again. His cock had barely stopped throbbing from his orgasm and it was already becoming rock hard once again.

It was Amanda's turn to take on the role of the hungry animal. She grunted something about my turn, pushed Dan onto his back and straddled his thigh. The no touch agreement was forgotten as she began to slowly grind her wet pussy on Dan's thigh. Her eyes were wild with passion and her body was burning with desire as she gyrated against him, her hands still spreading the gooey mess over her fabulous body as Dan stared at her in shock.

"Come for me again," Amanda whispered. "Come on me again big brother."

If Dan wasn't completely hard before he definitely got there quick when his sister started talking dirty. He had never imagined her as such a horny vixen, and it was clearly a turn on. He was so turned on, in fact, that he broke the no-touch rule himself, dragging his hand across her body to cover his hand in his own cum, then using it as lube to rub his own cock with.

The sight of her brother rubbing his cock in his own cum became too much for her, and Amanda shuddered and jerked as her body surged with an intense orgasm. Watching her thrash around became too much for Dan, as his second orgasm came much quicker than the first. It was every bit as intense, and long, and this time he unloaded his massive load all over himself.

Amanda sighed deeply and rolled off of him, coming to her senses enough to put some distance between them.

"Holy shit, I can't believe we just did that," she said. "If you ever tell anyone about that I will kill myself, and then come back and haunt you."

Dan laughed. "Your secret is safe with me."

They lay there for some time on the floor of the sexy bathroom, both of them covered in cum and intensely satisfied after a long week build up. Eventually Amanda spoke again.

"I suppose I should tell you, the last several days I've been spiking your coffee with dad's viagra," she said.

"What the hell," Dan replied. "You did what?"

Amanda blushed. "I was trying to make you horny enough to push you over the edge," she said. "I guess in hind sight that was a pretty bad thing to do."

Dan took a long breath in and let it out, thinking about how intense the last week had been. "Yeah, that's a pretty bad thing," he said. "I think you are gonna have to pay for that."

Amanda looked over at him, admiring his naked body beside her. "What kind of payback?" she asked, almost nervously.

Dan reached down and wrapped his fingers around his cock, which was unbelievably hard and throbbing once again.

"I'll think of something," he said, looking lustfully at her naked body. "I'll think of something."
