Chapter 2432 - MY CUM BUCKET: MY NERD SISTER

Okay, call me a snoop! I used my sister's laptop recently and the first thing I found was an open word document. I didn't walk away because it was titled 'Benefits of Cum'.

Was I shocked?

Yes.

Did it make my cock harden?

Of course... I'm a guy.

Before I go any further I should note that my sister was eighteen, sweet and nerdy... in a classy way (imagine Audrey Hepburn with glasses). She wore skirts and dresses every day and I'm pretty sure she actually wore pantyhose as part of her fashion statement. She was also super smart, had already been accepted to some colleges, but was striving to get into Harvard.

This dream definitely kept her busy and caused her a lot of stress, while I was going to community college on a basketball scholarship and still living at home. So even though I was in college and she was in high school, she was the one doing tons of homework while I did what I did best... I got by.

I noticed the document was stored in a folder called 'Mydiary', so it was personal, and a considerate gentleman would walk away without reading another word. But of course with a title like that, I couldn't resist. I mean I was curious as hell. So I went ahead and read it. As I said, call me a snoop. And get over it. I did.

After reading a lot of websites, it seems that ingesting male cum could actually help give me a mental advantage. Male cum has quite a few benefits to it and very few risks (disease of course being a pretty big one). Now not all the benefits would actually help me, although I find it fascinating that swallowing cum can actually help keep pregnant women from getting preeclampsia, a medical condition that can raise blood pressure and affect organs like the kidneys. And although cum contains oxytocin, a peptide hormone that helps increase trust with your man (and bonding with your newborn baby), I am not looking for a boyfriend (or a baby), since I want to focus on my studies and become a lawyer. That said, cum does have the following advantages that might be useful to me personally:

1. Research indicates that swallowing cum regularly will actually help the functioning of your brain. Cum contains lots of nerve growth factor which is a key compound for growth of neurons in your brain, and neurons are the little buggers that flash each other so you can think. The more neurons you have, the faster and better your thoughts become.

2. Surprisingly, cum contains antioxidants which are very beneficial to the body, including: superoxide dismutase, glutathione, catalase, vitamin C, vitamin E, pyruvate, carnitine and citric acid.

3. Cum also helps keep you healthy, as it contains such electrolytes as salts of calcium, magnesium, potassium, sodium, zinc and chloride... all which are vital for staying healthy (If this becomes common knowledge, the familiar slogan could turn into, 'a load of cum a day keeps the doctor away').

4. Although irrelevant to instant gratification, cum nevertheless contains a compound called spermidine that research has proven helps in anti-aging... which is a nice side perk along with the others, as I obviously want to live as long as humanly possible.

5. Lastly, although pretty minor, and not enough for the energy boosts I need most nights, cum contains a little bit of fructose and glucose; also, semen provides protein, which I don't get enough of.

Remaining questions:

1. Is girl's cum as healthy? (although I could never do that)

2. Could I actually suck a guy's cock just to get a dose of cum?

3. Why isn't there a CUM store down the block??? (LOL)

Future research:

Do more research on applications of cum to the face... does it really help the complexion?

I couldn't believe what I was reading. I had thought all those assertions about a man's cum being good for a girl's skin was simply bullshit made up by men for obvious reasons, but if Amanda had researched it, she would have researched it well.

I searched her computer and found a few more intriguing items, including some porn videos of oral sex, scholarly articles on oral sex, and another diary entry (after a few that were generic girl babble) where she talked about practising on a carrot, then a popsicle, and finally a cucumber.

Then I found another document called 'Tips to Sucking Cock'. Of course, I couldn't help but read this one too... curious about what she had learned. I had gotten head from probably a dozen girls in my life, and only a couple of them had been any good at it, and none of them qualified as amazing. My only amazing blow job had come from a gay guy at a college party when I was drunk enough to let a guy blow me (and once I stopped looking down and reminding myself I was being blown by a guy, I really enjoyed it; he knew exactly how to worship a cock.. sucking my balls, deep throating me, swallowing my load and then continuing to nurse on me until I finally pulled out). That was a good couple of months ago, and although I didn't want to keep relying on getting sucked by queers, I sure hadn't enjoyed the two following blow jobs from inept girls.

Tips to sucking cock:

1. INTRODUCE YOURSELF

a. Take it in your hand.

b. Stroke it.

c. Kiss it... the head, the shaft and down to his balls.

d. While doing the above, gaze sexily into the guy's eyes.

2. LICKING A CONE

A great way to start a blow job is by licking the entire shaft of the penis (it's good whether the penis is soft or hard). This beginning has multiple purposes:

a. It can get a soft penis hard.

b. It is a great teasing promise of things to come.

c. It will often have him begging for you to take it in your mouth.

3. BLOW HIS TOP

Although the entire penis is chock full of pleasure points from the ball sack, up through the shaft, all the way to the mushroom top... the head is definitely the most sensitive area (this is particularly true if the penis you are pleasing is uncircumcised).

You can tease the mushroom top in many ways:

a. Swirl your tongue around it.

b. Flick it.

c. Suck just the top into your mouth and create enough extra saliva that it will literally cascade down his cock.

d. Clamp your lips around his mushroom cock, suck steadily and slowly back off until you both (and any others present) hear a loud pop.

4. AND WITH HIS COCK BE HANDY

Although everyone assumes the mouth is the key to the blow job, and it is, the importance of the hand is often neglected. The hand is a critical implement for enhancing the full pleasure of a blow job. Using your hands is what can turn a good blow job into a great one. You can:

a. Stroke it to get it hard.

b. Use your hand to hold it in place for sucking, insertion or display.

c. Stroke it with one or both hands while you tease the head with your lips or tongue.

d. Caress the balls... oh so gently, please.

e. Pump and suck.

f. Stroke it until he comes.

5. PLAY BALL

The balls are another aspect of a man's primary erogenous zone. A man's testicles can be fondled, caressed, tickled and massaged with your hand. The balls can also be pleasured with your mouth or tongue.

a. Use your hand to gently caress them, possibly while using the other to stroke the shaft of his cock.

b. Kiss and lick them.

c. Gently suck each ball into your mouth (remember they are super sensitive and fragile, and thus be extra cautious and tender).

6. TEASE AND PLEASE

It's time to get to the main course. Take the cock into your mouth and begin bobbing:

a. Start slowly, taking more and more with each forward bob as you get used to having the cock in your mouth.

b. As you get comfortable, begin moving faster.

c. Always listen to his moans to assess how much he is enjoying your activities and how close he is to climax.

7. HEAVENLY SALIVATION

You have a lot of accessories available during a blow job. We have already discussed your hands, lips and tongue. You also have the ability to create excess saliva. This saliva can do a few things:

a. Get him hard.

b. Create a whirlwind of pleasure.

c. Create lubrication.

d. Enhance the pleasure of the blow job.

e. Create an exciting visual impact.

8. BECOME THE SLUT

Although men want a sweet woman in the outside world, they want a slut in the bedroom. They are stimulated by verbal excesses and will more likely come quicker if they are given evidence that you are enjoying yourself.

a. Moan while you suck his cock.

b. Play with your tits or pussy with your free hand.

c. Tell him how much you love his cock, how much you want his cum.

d. Beg for his load.

9. FINISH YOUR MEAL

No man will ever be flattered if you spit out his cum or make him come on himself. If you have 'become the slut' you will be willing to take his load in any of a few ways:

a. Swallow of course... just keep sucking until every available drop is in your belly.

b. Facial... many men will love the dominant power of coating your face with their sticky seed.

c. Open target... this is a mixture of swallow and facial... open your mouth wide and wait eagerly for your treat (some will go in your mouth and likely some on your face). Afterwards clean your face with your fingers and tongue and feed yourself his cum. Don't waste a drop.

d. Titty Lubrication... men love tits... all tits... so offer yours to his load (double points if you beg him to shoot his cum all over your tits, triple points if you're flexible enough to lick them clean afterwards).

10. OTHER TIPS:

a. Eye contact: make sure he knows you are loving his cock in your mouth.

b. Deep throat: after sufficient practice to gain experience... go balls deep and hold it as long as you can.

c. Stop and go: suck his cock, pull it out, say something nasty... repeat.

d. Vary the depth and timing: shallow, shallow, shallow, deep and hold.

e. Face fuck: when you get good at swallowing, allow him to face fuck you... allowing him to take control gives him full power over you, and his thrill of conquest will make him come faster.

f. If you gag on his big cock, make it loud. He'll love the compliment.

g. Prostate manipulation: if you know your man, surprise him with a finger in his ass right as he is about to come. WARNING: the first time he experiences this, be ready for a powerful eruption almost immediately.

h. Lastly, always take his cock back in your mouth after he comes. As mentioned before, coax out every drop.

I couldn't believe what I was reading; she had really researched this. Yet, as far as I could tell she hadn't actually done any of it yet. It was all theory and no practice.

Noticing the clock and realizing I didn't have a lot of time left, I grabbed a USB and saved her diary entries for further reading, erased today's history, and shut her laptop down.

That night, I stared at my supposedly sweet sister in her usual conservative attire, a blouse, a long skirt and pantyhose. Having a nylons fetish, I had always enjoyed the fact my sister usually wore them... even though since she was my sister I hadn't thought much about it... until now.

I gazed surreptitiously at her lips and couldn't help but imagine them wrapped around my dick.

I imagined her following the procedures she had learned to get her daily dose of brain food or facial cream.

I imagined her begging to suck my dick.

Fuck! No matter how much I kept reminding myself she was my sister, I couldn't stop thinking of her giving me a blow job.

My dick hard, I went to my room, and decided to read more of her diary. Unfortunately this cock sucking thing was a relatively new idea for her, so there wasn't a lot there. Nevertheless it was worth examining.

There were a couple of vague entries like:

I can't stop thinking about it.

Why can't I get the picture of it out of my head?

As I kept scrolling down, I finally figured out what she couldn't stop thinking about and what picture seemed permanently implanted in her head. And WOW did it shock me to the core.

Oh my God I just saw Jason's penis as his girlfriend was sucking him. I should have been aghast but I was utterly in awe of the act. Tamara on her knees, bobbing back and forth. I should have left ASAP, but I was completely transfixed by what I was witnessing.

And when he ordered, "Get ready for my cum," and Tamara moved her mouth off his penis and opened up, I just stared even as I felt my own mouth open, mirroring hers.

"Want my cum, my little slut?" he asked, and I felt a gush in my panties at his dominant treatment of her, even though I should have been mortified by his chauvinistic attitude.

I expected her to snap at him for calling her such a name, but instead she responded, "Yes you stud, cover your slut's face with your hot cum."

I watched Jason stroking his really big penis (way bigger than the one I'd jerked off once at camp), in awe of its length and girth. "Oh yeah, get ready, my little cum slut," Jason groaned, as he furiously beat his penis. I was confused at my body's reaction as my vagina got tingly and I felt wetness flood my panties.

Tamara demanded, "Give it to me baby. Coat my face."

I couldn't believe that someone like Tamara would talk so nasty, nor could I believe how much it turned me on... even though I should have been appalled by such derogatory treatment of a woman. I mean I had written my college prep essay on the evolution of feminism and the female heroes who overcame sexism to lead the way to gender equality.

Yet at the moment, I was horny as hell... way hornier than usual.

Then it got even hotter as I heard Jason grunt and watched his cum shoot out of his penis and splatter all over Tamara's face.

I couldn't help it. At that moment I wanted to suck that penis and to feel that cum landing on my face as I forgot who was attached to that penis.

Knowing I could get caught any moment, I crept away and scurried to my room where I masturbated like I do most nights... with the dildo I'd bought on eBay.

After I came, I felt incredible guilt because I had watched and gotten horny by staring at my brother's penis in action. Yet three hours later I'm still replaying the sight in my head.

I don't want to have sex yet... that I'm saving for marriage... but the idea of sucking a penis... well that I may have to do some further research on.

The first cock that intrigued my sister Amanda was none other than MINE!!!!!

MINE!

MINE!!

MY OWN COCK!!!

Holy fuck!

I reread all her diary entries, now incorporating the new information that the cock she was talking about was mine, but although I now felt it more personally, I didn't learn any new information.

My cock rock hard, I wished I hadn't broken up with Tamara a few days ago. She had been way too needy, although she was a hot little slut and one of the more talented girls ever to blow me... although not amazing by any means. A front runner in an unimpressive field.

So I jerked off and came in under a minute... the idea of making my sister my own cum slut was suddenly all I could think of.

That said, I really had no idea how to make such a thing a reality... it was one thing to jerk off to it in fantasy, it was another to commit incest with a living person.

Yet, as I logged out of my computer I'd be lying if said I wasn't thinking about it.

.....

After a couple of days I couldn't handle it anymore. I knew it was wrong, but I wanted... no, I had to have my sister as my cock sucker. Somehow I just knew she would be a natural... she was good at everything she did and I imagined with a little practice she would become an amazing cock sucker... plus, according to her research it was healthy for her, both academically and for her complexion. Sucking my cock would help her get into Harvard! (But only if she swallowed.)

So really... If I let her suck my cock I would be doing it for her... I would be an altruistic benefactor of her desires and needs. What a guy!

Yet, I had to be sure she wouldn't freak out if I offered her my cock and cream.

So the next day when she was at school, I skipped my college classes, which truthfully if you can read a textbook you can easily afford to do, and I went back into her computer looking for more evidence and hopefully an update to her diary.

I clicked on the diary first, as I saw it had been updated, and my cock rose as I read it:

It's getting worse. All I can think about is sucking cock and every time I see him I glance at his crotch... which always seems to be bulging... and I crave it. I want to be a cum bucket.

Reading stories online is making me feel less resistant to breaking the taboo about what I am fantasizing about. It seems that incest (especially between mom and son or sister and brother) is a rather common fantasy, and is also played out in reality a lot more often than society would like to admit).

I'm not sure I could EVER actually do it, but my sudden obsession with it is making it hard to focus on my studies. It's one thing to fantasize, and completely another to actually become your own brother's cum bucket!

God, do I need a boyfriend!!!

That was written last night. Probably while I was jacking off thinking of her!

WOW!

I skimmed down the screen, but the only other new entry was about her Calculus test. She'd gotten 98 percent on it and was obsessing about what she'd gotten wrong.

Curious, I searched her internet history for what kind of stories she was reading. There were quite a few, including: Cocksucking College Sister; Brother's Dick: A Virginity Lost; A Mom & Son Affair: Accidental Orgy; A Sibling Love Story; Best Present Ever: Bitch Sister; Blackmailing Bitch Sister; Family Affair: Backseat Sister; Journey of a Submissive; Musical Dicks: A Sibling Fuck Story; Revenge of the Nerd: Bitch Sister; and Tricking Twin Sister. I read each one, noticing that she had bookmarked Cocksucking College Sister, Family Affair: Backseat Sister, and Revenge of the Nerd: Bitch Sister.

I found this interesting, as one was obviously about simple cock sucking, but Family Affair was about a nerd girl who had a crush on her brother (just like she seemed to have on me). While Revenge of the Nerd was a mind control series where a sister is mentally transformed into a sister slut.

Not surprisingly, this made me horny as hell and I pulled out my cock and jerked off, coming quickly into a Kleenex. Once done, I went to toss the Kleenex in her garbage when I saw a cucumber in the basket.

Instantly, I wondered... had she used that for what I thought she used it for? I pulled out the cucumber and although this may sound kinky, I brought it to my nose and took a big sniff.

As expected, I could smell the scent of pussy.

I smiled. Reading stories about sucking and fucking siblings had gotten her turned on enough to fuck herself with a cucumber. I closed my eyes and paused to enjoy the visual that thought inspired.

Confident I had enough evidence to take the risk, I began my plan to seduce my sister.

The next day, with our parents out for the night at their Christmas party and not expected home for hours, I decided to go for broke.

I bought a used cell phone for a few bucks, got it activated by prepaid cards and decided to try to seduce her with my cell.

I texted her, keeping it simple at first:

UNKNOWN CALLER: I know your secret!

I knew she was home in her room and wasn't surprised when I received a text a couple of minutes later.

AMANDA: Who is this?

UNKNOWN CALLER: Someone who can help with your new curiosity.

AMANDA: I don't know what you are talking about.

UNKNOWN CALLER: Online searches of porn stories are easily traced, Amanda.

My cock hardened at what I was doing... hoping that tonight I wouldn't be jerking off, but having my sweet sister blowing me.

AMANDA: How do you know me?

UNKNOWN CALLER: Answer my question or I let your classmates know you are looking for cum to help you study better.

AMANDA: OMG! Who is this?????

UNKNOWN CALLER: I ask the questions. Have you yet sucked a cock?

I waited a couple of minutes and there was no response... having discovered where she researched her cum curiosity I pushed the envelope.

UNKNOWN CALLER: Answer me. Or are you back on the 'Bad Girl's Bible' site learning about the benefits of cum?

AMANDA: Please... don't do this.

UNKNOWN CALLER: Have you ever sucked cock?

AMANDA: No.

UNKNOWN CALLER: Do you want to?

Again a lengthy pause. I'd originally planned to have this last awhile, but I suddenly felt guilty. Not at planning to make my sister my cum bucket... no, I was completely on board with that... but I felt bad about making her feel like she may be outed or blackmailed.

After I heard through the wall that she was cursing... not angrily but fearfully... I realised I was causing her extreme anxiety, and that wasn't good at all. I decided to end the anonymity and just bluntly offer her my cock.

I got naked, put on a robe and knocked on her bedroom door. I asked, "Amanda, are you okay?"

"I'm fine," she called back, obvious from her tone that she definitely wasn't fine.

I continued, "Let me in. I can tell that you need to talk."

I heard a heavy sigh, but a moment later she opened the door.

I walked in and asked, "What's wrong, sis?"

"Nothing," she answered, her eyes red; clearly she had been crying.

"I've known you all my life," I said sympathetically, as I followed her into the room. "And something is wrong."

"I'm just stressed," she said, turning back to me. I now stood directly in front of her.

"I think I can help you with that," I said.

"No, there's nothing you can do about it," she said. She was close to despair.

"I'm pretty sure I can solve all your problems," I said confidently, as I acted on a decision there could be no retreating from, no possible denial of my intent. Brazenly, I opened my robe to reveal my hard, eight inch cock. I added, "I think I have the perfect cure for your stress."

She stared down at my cock, speechless.

"Isn't this what you've been craving?" I asked, slowly stroking my hard cock, feeling rather like a tropical bird performing a mating dance.

She looked back up at me as realization suddenly hit her. "That was you?"

I nodded. "Yes. But I realized I was being cruel, and I don't ever want to be cruel to you. I love my baby sister, and I want her to be happy." I placed my hands on her shoulders and guided her gently to the floor. "So now it's time for you to discover the joys of forbidden fruit."

She didn't stop me as I guided her to her knees. She stared up at me in disbelief and then down at the erect cock staring her directly in the face.

For a moment, maybe fifteen seconds, there were no words, just my brainiac sister trying to understand what had just happened, even as she didn't, couldn't, take her gaze off the forbidden fruit.

Finally, as if suddenly remembering I was her brother, she protested, even though she made no effort to move away, "But you're my brother."

"Yes, and you are my cock hungry sister," I firmly responded, as I slid my cock into her open mouth.

Her eyes widened in astonishment as I slowly pumped her mouth with my cock, for just a few strokes... she again making no effort to stop this incestuous act.

When I pulled out, I explained, as I looked down at my dazed but unresisting sister, "I know you saw Tamara sucking me, I know you've been researching sucking cock, and I even know you've been reading sibling incest stories. And I know...." I paused, to let my words register in my sister's head... "that you want to be a cum slut."

As she stared at my cock, now slightly wet with her saliva, she prevaricated, "It's one thing to fantasize."

I finished, "And completely another to become your brother's cum bucket. That's the phrase you used in your recent diary entry is it not?"

She finally broke her transfixed stare at my dick and looked up at me in shock, "You've been reading

my diary?"

"I have, and you can be happy I have," I said, as I slid my cock back into her mouth. "There is nothing worse than living in denial and hiding away those feelings... It's not healthy. Cum, as I've learned from your research, is apparently very, very healthy."

Again she didn't stop me as I slowly fucked her face, allowing me, as I'd suspected she would, to take control of her.

I continued, "I love having a submissive little slut to suck me whenever I want, and having a live-in cum bucket is even more convenient. Plus, we both get what we want. You get your brain snack or your facial cream and I get a sexy cum bucket where I can deposit a few loads per day."

She couldn't respond as her mouth was full of cock, but when I pulled out a few slow strokes later, she looked up and said doubtfully, "But this is incest."

It was obvious she desperately wanted to do this, her body language, her weak protests and her not stopping me as I fucked her face all key clues... yet, her rational mind clearly hadn't yet caught up to the visceral decisions of her body.

"Incest is the theme of all the stories you've been reading online," I pointed out.

"How do you know about that?" She asked... which was cute how naïve such a smart girl could be. If I could read her diary on her computer, I could obviously check out her internet searches.

"You probably should erase your internet searches and put a password on your laptop," I suggested, as I slid my cock back into her mouth.

This time, though, I didn't fuck her face.

Instead, I stopped halfway in my sister's mouth and ordered, "Now suck me, my sister slut." Calling her 'slut' was unfair since she was a virgin in all ways other than masturbation (I had the sworn testimony of her cucumber to remove any doubt on that point), but based on her diary entries, and my own sexual experience, I was confident my dominant attitude and name calling would tilt her decision over the edge and impel her to commit the forbidden sin on her own accord.

She didn't move at first, just knelt there with my cock resting between her lips, as if she were contemplating her next move... although obviously there was nothing but her own desire stopping her from standing up and walking away from me. She could have done that the moment I'd first taken control, but she had complied so passively that she had already committed the sin.

But I wanted her to make the next active move.

I wanted her to deliberately decide to become my sister cum bucket.

I wanted her to cross the line from fantasy to reality all on her own. I had of course gently fucked her face twice already, so I was expecting her initial actions to be anti-climactic.

If matters progressed according to my plans of course, her subsequent actions would be completely climactic when I came down her throat. I had refrained from coming for two days, an eternity for me, so I was hoping also to shoot a second load all over her face so she could experience cum as a food group followed by a facial cream.

I'm not sure how long she knelt there with my cock in her mouth, perhaps ten to fifteen seconds, although it seemed excruciatingly longer, before I felt her tongue begin to swirl around my mushroom top.

I smiled as she began to service me, following, it seemed, the notes she had typed. I didn't say anything at first, as I allowed her to begin pleasing me. I just watched her from above in ecstasy at being the first cock in her mouth. As well as, of course, being thrilled to be getting a blow job from my sweet sister... something I imagine many brothers fantasize about.

"Now start sucking," I ordered, after a minute of gentle pleasure as I wanted to deposit my first load down my new cum bucket's throat.

As I had hoped, she obeyed, beginning to bob tentatively, obviously getting used to having a cock in her mouth.

I just stood and watched her suck, my balls starting to bubble in no time at all. For a rookie cock sucker, she was a natural; she took more and more of me in her mouth with each forward bob, while thoroughly coating my shaft with her excessive saliva.

I warned, "My first load is coming soon, cum bucket. It's going right into your mouth, down your throat and into your belly."

To my delight, she not only began bobbing faster, but she moaned.

Seconds later, my sister officially assumed office as my official cum bucket by extracting a full load of the healthy cum into her eager mouth.

"Oh yeah," I groaned, "the first load of many."

She kept bobbing for a moment, but the big load I had been saving for her was too much and she gagged as she backed off my cock and my last squirt of cum hit her in the forehead and some of my cum dripped out of her mouth and onto the floor.

To my surprise, she returned her mouth to my cock and resumed bobbing, extracting any late comers (haha).

When I pulled out, I joked, "I guess you need more practice to catch it all."

She licked my shaft, as she said, "None of my research could have prepared me for how much cum was in your balls."

"I'm usually fully loaded," I shrugged, looking down at her.

"So I learned," she said, shocking me again as she scooped a wad on the floor and put it to her mouth.

I pointed to her forehead, "If you're still hungry there is a bit resting on your forehead."

"I think I'll have a constant craving," she responded, as she moved her finger to her forehead.

"Thankfully I have a constant supply," I said, thinking that was one of the best blow jobs ever... partly because of her eagerness and partly because she was my sister.

"I can't believe I just did that," she said, not ashamed, but thrilled... a naughty twinkle in her eye as she extended her tongue and licked my cock head once more searching for cum that wasn't there.

"I couldn't believe what you were saying when I read your diary," I responded.

"I can't believe you read my diary," she said, as she stood up.

"It wasn't on purpose," I admitted. "I left my laptop at school and needed to do some research, and your diary was already open. I became so engrossed in what you'd written that I never did get to the research. I just began plotting your seduction."

"I guess I really should get a password," she laughed.

"Yeah, you wouldn't want anyone else to know you want to be a cum bucket," I smirked.

"I'm not sure one load makes me a cum bucket," she pointed out, even as she smiled wickedly.

"How many loads make you a cum bucket?" I questioned.

"How many loads do you have?" she asked, as she reached for my cock and began stroking it.

"More than you can handle," I replied.

"Is that a challenge?" she asked, my sweet sister turning into a sultry siren right in front of me.

"Definitely," I nodded.

She returned to the carpet, looked up and asked, "How long can you stay hard?"

"Only one way to find out," I shrugged.

She nodded, "Time for some hands-on research."

As she took my cock back in her mouth, I joked, "I think you mean mouth-on."

She moaned on my cock again as she again swirled her tongue around my cock head. After a minute, she moved back off and slid her tongue down my shaft and to my balls.

I watched and enjoyed as she sucked and cupped each of my balls in her mouth... which felt amazing.

After a couple of minutes she slid her tongue back up and returned to my cock head. She said, "God, I love your penis."

"It's a cock," I corrected.

"God, I love your big, hard cock," she reworded, looking up at me adorably as she said it.

"That's the hottest thing I have ever heard," I said.

"How about 'I want you to fuck my face and cum all over me'?" she asked, as she took my cock in her mouth and deep throated my entire dick.

"Oh, God," I groaned, impressed by her insatiable hunger.

As she pulled back out, "How about 'I want to be your sister cum bucket'?"

Again she deep throated me, holding her face buried in my pubes for a good ten seconds before pulling back out.

"And how about 'I want to suck your cock for breakfast, for lunch and for dinner'?" she questioned, again returning to my cock... this time bobbing furiously.

"Oh yes, suck it, my sister slut," I groaned, not sure I was being dominant anymore if she was taking the initiative by talking so nasty.

For a few minutes, she sucked.

For a few minutes, I groaned.

For a few minutes, she moaned on my cock as her hand went under her skirt to her pussy.

For a few minutes, I called her names.

For the second time in a few minutes I could feel my cum bubbling inside.

So close... I grabbed her head and face fucked her. I loved hearing her slobbering sounds as my balls bounced off her chin.

"Oh yeah, my live-in cum bucket. Get ready for your brother's creamy load," I grunted, before pulling out at the last second and splattering my load all over her pretty face.

She closed her eyes just in time as she faced up to my sticky seed.

Once I was done, she opened her left eye, the one I hadn't come all over the lid of, and took my cock back in her mouth. She sucked me for a few seconds before standing back up and rubbing my cum all over her face.

It was fucking hot.

I chuckled, "So you really believe cum helps the skin?"

"Only one way to find out," she smiled.

I shook my head as I promised, "Well if it does, you'll have a steady supply of the cheapest face cream ever."

"Well the price sure is right," she smiled, as she sucked her cum covered fingers into her mouth.

"Hey," I realized, "you haven't come yet."

She shrugged, "It appears I do my best work when I'm horny."

"Well," I said, as I went to her bed and laid down, "Let's see if that's true."

She smiled, "I may never get any studying done at this rate."

As she crawled between my legs and took my cock back in her mouth, I said, "Well, if your research is reliable, the more cum you eat, the less studying you'll have to do."
