Chereads / Taboo Incest sex stories / Chapter 3785 - SHARING IS A WONDERFUL THING

Chapter 3785 - SHARING IS A WONDERFUL THING

"Ah! Harder, right there~" Kate's voice came clear through the cardboard-thin wall of the apartment to the waiting ears of her sister sitting in the living room, not that she would have known (or cared if she had known) that Lydia was even there.

Lydia sat in the couch, half-watching television with the volume down because she actually cared whether she was bothering other people. It was just too damn hot for all this, and she resented that she had to wear shorts as well when all she wanted to do was sit there in her panties and a tank top, if that much, with a handful of ice cubes against her neck. All she had to beat the heat, since she and her twin sister had agreed that they should save money by keeping the AC use down this year, was a popsicle that she was not biting and chewing as she typically would because she wanted it to last.

She licked up and down its length, catching drips on her tongue hopefully before they splattered on her chest, even though it was only for the sake of a five-dollar top that had come in a pack of ten with the seeming cheap thickness of butterfly wings. And she wasn't doing it for the sake of Kate or Trevor; the man only had eyes for his girl even though the two of them looked nearly identical, would look identical if Lydia put the same number of hours applying makeup into her look as her "big sis" did. It didn't matter one whit if the man caught a look at her cleavage, wet or otherwise.

It had always been this way, Kate putting out and Lydia sitting back to let her, all the way back to school when one thing led to another and this guy got fired and that whole fiasco. Nearly eight years on, it still seemed like yesterday when they were still in their parents' house and Lydia was the one helping Kate sneak in her boy toys, going down to chat with mom and dad while whoever it was that week hauled himself up the ivy to the second floor window. Now, Lydia could hardly go one day without coming back home from work to her sister's moaning, and the bitch barely even apologized for it anymore!

No... no, not a bitch... Lydia had trouble thinking of her that way. She really was a good person otherwise, she just really liked sex and didn't have trouble finding it. It was just hard to think of her other decent qualities: her charity, her kindness, her forthrightness, when she was currently getting herself pounded down in the next room over! At least now she was going out with a decent guy, and it had even been the same guy for a few months, through spring and into the disgusting heat of summer.

Speak of the devil, the moaning had ceased and the man himself made an appearance coming out of Kate's bedroom. And, being a decent guy, he took stock of the room and covered himself as soon as he saw that Lydia was in fact home, dipped to pick up his boxers (discarded outside the bedroom door) and slip them on.

"Sorry about that, Ly," he said.

He'd begun finding some more clothing, but she waved it off from her place slumped over against the sweat-damped cushions of the couch. "Don't bother, it's too god-damned hot to worry about dressing up."

Trevor laughed it off and went to the kitchen, taking out a carton of orange juice.

'Of course he needs to get ready for another round,' Lydia thought with an inward eye-roll.

"Want anything while I'm in here?" he called over.

"A gun with one bullet, two if you're in for a murder-suicide. Maybe hell'd be cooler."

He sat on the other side of the couch and instead with a laugh handed her an ice-cold cider that he must have brought himself. "Afraid this is all I can do. You watching this or just needed something to take your mind off the heat?"

She shrugged, cracking the can and taking a long drag of the overly-sweet brand. "You're some kinda sissy, you know that?" she said, against the evidence on display of his daily workout routine, wonderfully defined abs and this... and that... Lydia averted her eyes to the glare of the sun still making it through the blinds on the west side. "No, watch what you want. Guess she's taking a nap?"

"Got it in one," he said, "and I'm a man, I'll drink what I like."

"Bet you like hot chocolate, too? Can't take coffee?"

"With marshmallows, cream, and sprinkles." He really did have a nice smile... "Just gonna watch this cooking thing if you don't mind, while I'm waiting."

Lydia closed her eyes. "I just said you could watch what you want. Real men take what they want, don't they?"

"I don't know about that."

Then there was the sound of sizzling steak. Someone on the television was living their best life on a beach with steak grilling, bastard. And Trevor, being compassionate, switched to a nature documentary about seals. Though, of course, Lydia had to open her eyes once more; who could resist the pull of cute seals?

"So, uh," he said, "you didn't hear too much of that, did you?"

She wanted to roll her eyes, but he was too sincere to do that to him. "Only from about the point she was asking you to spit on her asshole."

Trevor flushed, or at least the fidgeting made it seem that way. Who could really tell when the default state of the season was pig sweat?

"Sorry about that. Seems like it happens too often. Want to give me your number so I can call or something when... That would be even more weird, wouldn't it?"

"Getting a call to the effect of 'I'm about to plow your sister'? Yes, I'd rather just follow the moaning if it's all the same to you. Don't worry, I'm more or less used to it."

"If you say so. We were thinking of ordering out for dinner. Anything you'd like, my treat?"

She waved off the suggestion and tried to fan herself for the little benefit of passing warm air over a warm face. "Wasn't going to eat tonight, 'cept more ice cream. Anyway, why don't the two of you go over to your place for this? I bet you've got ac."

Trevor laughed, reclining much like she was, put his feet up on the ottoman and spread out his toned arms, nearly brushing against her naked shoulder. "My roommate is less understanding than you are, kind of a creep if I'm being honest. But you know, old friends, can't do much about it."

"Worried he'd try and get nude pics?"

"Yes," he said with terrifying dis-irony. "And the heat doesn't bother me all that much, low body fat, I think."

"So I'm fat?" She grinned.

He shrugged. "I call Kate curvaceous, you're the same way. It suits you."

'Right, I just love being compared to little miss sex-pot.' Her smile faded but she didn't lash out; actual sincerity was a hard thing to deal with.

"Sorry, that was out of line," he said right away. "I mean, no, you're not fat..."

"Yeah, sure."

He sighed. "When you date one half of a pair of identical twins, you can tell me all about the difficult part of giving compliments."

"I said sure, didn't I?"

"But you're angry."

"Drop. It."

He raised his hands in a conciliatory gesture and they went back to watching the screen in uncomfortable silence.

Silence, that was, until Kate came out of her room, stretching and yawning in about as much clothing as Lydia wished she could get away with at the moment: thin cotton panties and a cropped tank that hung like a curtain off her swinging tits, already partway to see-through with sweat. She came up behind her boyfriend and threw her arms around his neck, nuzzling his head between her breasts and her chin atop his curly, brown hair. "Reverse commando style, I like~" she said with a passing kiss as she extracted her sticky self and went to get something to drink before getting heatstroke.

"I'm here too," Lydia said.

Kate padded back with a lager, settled into her boyfriend's lap and pasted herself to his chest. She wagged her finger. "You're also very sexy. Love the cotton shorts, showing off the belly button is nice too."

'It's too hot for this shit.' "Just bakin' away brain cells, aren't you? Sleep with a damp cloth tonight."

"Rather sleep with you~" Kate teased in her wavering way as though the alcohol had already done its job despite only having had a few sips yet. "Maybe run a cold bath for us both? Like old times?" She poked Trevor's cheek; he'd been looking away. "Wanna watch us squish into our little tub together?"

Lydia nipped it in the bud. "We are not going to bathe together, and we never have."

"Sure we did~"

"When we were five!" Lydia regretted raising her voice immediately and sank back into her seat on the couch, it was too damn hot to let herself get worked up like that.

That had been a constant annoyance, spanning all the way back to when Kate started acting out. She'd entice the day's 'boyfriend' with fantasies of the two of them and Lydia would have to be the one to turn them down the next day when they'd been unceremoniously dumped. 'Forgive me for not wanting my sister's sloppy seconds!'

"But really," Kate said, "it's a scorcher today, isn't it? Should we just eat the cost for the cooler?"

Lydia groaned. "It's too late for that. We'd only get a couple degrees cooler before sunrise tomorrow, maybe."

-

The following day broke city records for heat. It was so hot that rather than flock to the restaurant for cold drinks, the patronage had instead decided to stay home and do whatever they could to beat it without walking out into the blinding sunlight. Lydia, therefore, had gone five hours without a single customer, without a single tip, and she'd run out of things to clean four hours earlier. The lunch rush, such as it was, consisted of one old man who had decided to take the table with the most direct sunlight possible, and ate his light sandwich slowly.

So, at the stroke of five in the afternoon, with the whine of the restaurant's struggling ac unit overhead, the three waitresses sat around the coolest table along with the two chefs. Lydia sprawled across the tabletop, trying to expose as much surface area to the air as possible without touching Mable across the way who was in much the same predicament.

And the manager returned from the back with a case of frosty beers from the walk-in and a hastily-created sign informing potential customers of an early closure. "I'm guessing nobody cares if we all go home early? Take a fountain drink or whatever you want, I don't want to hear that anyone needed to go to the emergency room for dehydration on the way home."

A round of deflated cheering later, Lydia bore the heat of her car's fake leather seat, cursed herself the whole way home for going with metallic accents on the steering wheel, and came to her front door hoping the brief walk from the parking lot hadn't given her sunburn already.

On entry, she was met with the wonderful sensation of a winter wonderland, or the closest thing. "She must have left it on all day..." she remarked lazily, shutting the door behind her quickly as to not lose too much cool air. The chill hit different through the sweat-through bits of her clothing and she discarded it all once she was confident nobody was home.

That was weird, Kate usually worked the morning shift, but a note left on the counter explained the mystery before Lydia could get into it: 'Home late, monthly inspections.'

Whatever, Lydia would have felt fine being nude around her anyway; there wasn't anything either of them couldn't see with one or two mirrors anyway. It was hard enough, in Lydia's opinion, to see one's sibling as a sexual being, much harder when you knew about the beauty mark on their left buttcheek because it was in the same place as your own.

A lukewarm shower felt marvelous, finally getting the sheen of the day off and coming out without immediately getting sweaty all over again. Lydia did take a look in the mirror, since there had been no chance for fog to form.

So, this was curvaceous? She slid her palm down the line from her chest down to the swell of her ass. Puffy nipples were getting hard from the relative chill, goosebumps rising on pale skin. At least it didn't look like the start of sunburn, she checked over her freckled chest.

But then, she wasn't just like Kate, was she? There were those slightly beady eyes, the dull lips, colorless cheeks. She looked down to the mess of makeup used to keep her sister looking like "the hot one" strewn across the counter. Even in the full heat of summer, she'd only switched over to hot-weather versions of her normal products, things Lydia had never had an interest in, no matter how many times she'd let Kate cajole her into trying it for a night over the years. It had always felt like she was wearing someone else's face, that any attention she got from it wasn't worth anything since she'd just wash it down the drain later anyway.

She picked something up: a lip stain, whatever that meant... probably a stain for your lips, she made the connection pretty quickly and felt stupid enough for it. Uncapped, the applicator had the kind of vivid redness glistening at its tip that Kate tended to have. This, at least, should be easy enough to apply by herself, she thought.

But... it wouldn't look right without the rest of it. She saw her hand lifting it up to her lip in the reflection of the bathroom mirror and consciously put it down. She would only look creepy with the one product, and she couldn't trust herself to put the rest on without looking completely like a circus clown.

She didn't realize she'd left the bathroom door open until she heard the front door close. He'd already taken the few steps to the bathroom as the front door shut by its own weight, and he was in the doorway, staring.

"My god, I wish I had my camera out... you're stunning just like this." Trevor stepped inside, pushed her hand with the stain inside to the countertop as he took her cheek in hand and pressed his lips to hers. Against the counter, there was nowhere to run as he put his arm around the small of her back and pulled her tight, kissing her with sweet, slow intensity like dripping honey, the warmth of his touch somehow welcome after her lukewarm shower.

He was firm, taking what he wanted, slipping a hand to her ass, tickling the fingertips of his other hand across the nape of her neck, combing into her wet hair. Was this how Kate liked it, being taken without a word? The intensity of his lips left no room to tell him what was happening, what mistake he was making, and Lydia could feel herself warming up again just thinking about how increasingly awkward it would become with every passing moment of stolen intimacy. She'd been holding her breath, pursing her lips, but it couldn't last and she gasped in the instant Trevor came off, breast pounding to catch up, heart beneath that tightened and painful. She could hear the moan in her voice, saw the lust glowing on Trevor's handsome face.

'What am I doing? I have to tell him before anything else... happens...'

"We should stop..." she said.

Trevor held her gently in his arms, her breasts pressed to his firm chest, his leg between hers pinning her to the countertop. He kissed her forehead. "I've told you before, you're beautiful just like this too. Come on, we still have a few hours, don't we? Why not give her a break for once and do it while we're alone? Or," he said, "do you think I smell?" His smile, it was gorgeous...

Lydia gulped down her anxiety. "Y-yeah, you smell... so you should take a shower, yeah... That's, that's a good plan..."

He bent and kissed her lips again, not letting her go that easily. "Then, want to do it in the shower again?"

'What the hell has Kate been doing all these years!?'

"Actually..." She considered her options, her own clothes were just out there in her own room, so all she really had to do was get there and this all could be swept under the rug somehow... "You should do it alone..." She looked up into his steely blue eyes and tried to emulate Kate's teasing grin, not for the first time... and she twirled her fingertip on his chest. "I don't think we'll really get clean that way~"

'Guh, too saccharine.'

"If that's how you feel, I'll make sure I'm nice and minty fresh when I meet you in bed." Again, he kissed her, but finally untangled their bodies so he could begin undressing, dropping his jeans and his boxers in such a fluid motion that there was no way not to take a peek at his package as Lydia snuck toward the door and freedom. Not too fast, that would be suspicious...

Would Kate just leave like that? No...

Lydia took one step, within arm's reach, and cradled Trevor's hot, sweaty balls in her palm for a second, then winked and finally left, closing the door behind her.

Fianlly free, she gasped for breath and knelt, trying to calm her racing heart. It would all be okay as soon as she got to her room and changed, that was all it would take... Then she could say Kate had to leave on short notice, that she'd just come home early and didn't see a damn thing...

She passed the open door to Kate's room... She went inside... Something racy was hung on her desk chair, red and lacy, with holes...

They were in Lydia's size, because of course they were... It wasn't as though they hadn't shared clothes in the past... There was nothing sexual about it, just that their styles had been too similar to bother filtering them out of the wash... But this, this was the kind of thing Kate wore to get her boyfriends' hearts racing? It seemed too simple to be true, just showing off her puffy nipples and giving free access to her cunt. She had to be doing something more than being available.

It wasn't that Lydia didn't ever want a boyfriend, not even that her sister was making it impossible to find one. If she'd really made an effort to be likeable, or she'd been okay with leftovers, it wouldn't have been that hard to lose her virginity by twenty-four... last year... with someone who'd called himself a friend...

She had the bra in her hand, barely felt the weight of the gossamer lace against her skin. She put it on, tied the panties onto her hips, and stared at the image of her own sister in the bedroom mirror. Dark red laid well on pale skin, played with contrast. She pulled her hair into a ponytail, taking a tie from the dresser top to hold it. Spitting image, save the sullen expression and the dark circles. She smiled and blurred her vision, and it was like Kate was standing right there before her...

'I'm pathetic.'

Then, arms from behind draped across her shoulders, something hard prodded between her thighs. "So you do want to? I was worried you weren't up for it," Trevor said and blew a chilling puff of air into Lydia's ear that gave her the shivers after so long in the heat. "Oh? Nice reaction."

He was so warm, holding her close, his hands so tantalizingly nearby her breasts but stayed at the ready for her okay. A minty scent came off the places they touched, soft skin fresh out of the water. His dick was becoming hard between her thighs, starting to prod at the point of no return. She worried that he might be able to feel the way her heart raced against his broad chest, that only that much would be enough to figure her out.

"You didn't have to dress all sexy for me, you know." He kissed her cheek softly and at last her breasts lay against his open palms, firm nipples tickling his skin as he began massaging. "After all, I'm just going to take them off right away. I know how much you want to be naked."

Lydia tried not to shiver at his touch, tried harder and failed not to moan as her took her puffy nipples between his thumbs and forefingers then began gently rolling them. She could feel herself melting into him, rolling her hips against his lap unconsciously with his manhood pressing itself intently from below. It wasn't like she didn't have these feelings... It wasn't as though she'd never listened to these two through the thin wall connecting their bedrooms and touched herself until the three unknowingly came together... A heat built in her chest, flowing down and burning in her loins as her lips became wet without her permission.

The body knew what it wanted and the brain was just along for the ride, screaming out directions from the passenger seat. By the time Trevor released her to put on some slow, romantic music for the room, she felt too dizzy to think of an escape route. There was a feeling running through her body, undefinable for its shamefulness. She was still standing there, waiting, when Trevor returned and took her in his arms again, face to face, slowly groped her ass as he urgently kissed her.

'It's not my fault,' she told herself. 'It's just a misunderstanding...'

When her tongue met his, there was a burst of mutual excitement. It became difficult to pick out his and her moans below the cloud of saxiphone music drifting like steam through the air. Lydia couldn't guess how well her own sister kissed, but Trevor didn't seem to mind whatever difference there was. He came at her like he was starving for her touch, like the minutes between their lovemaking in the morning and now had been agony, like she was the most delicious thing in the world and he was so glad that she belonged to him.

Lydia spread out her fingers on his broad, muscular chest. His heart was racing too. She'd expected him to be entirely calm doing what he'd done so many times before, but the flashes she saw of his chiseled face in the dark room were uncertain, boyish. If it weren't for the skllful movements of his hands across her ass, spreading and squeezing and stroking, she would think that he felt almost virginal himself. It made her want to guide him through things, as if she had more than two of these experiences to bring to bear anyway.

After blissful minutes, he broke from her lips with a fragile strand of saliva falling on her chin. He bent to kiss her cheek, then trailed them tantalizingly down the side of her neck. He kept going, laying kiss after tender kiss across her collarbone, then smiled as he began down into her cleavage. He didn't do more than bury his face in her tits as he made his way down to her belly, kneeling as he did and taking hold of her thighs. And after a quick lick to her navel, he was face to face with the promised land that she was terrified he would not recognize.

"You're so beautiful. I don't tell you enough," he said. "We won't be needing these, now, will we?" He was holding the strings holding the borrowed panties on her hips; only one tug would release them and she'd be shorn of the mere inches of coverage they provided.

"I-I," she stammered. And she traded in her self-respect. "No, take them off..."

One tug. They nearly fluttered to the floor for how light and filmy they had been. Trevor wasted no time pulling her hips to his face, he pressed his lips against her, took a long, sensuous lick from her thigh all the way along her aroused lips, with a considerate smooch capping her firm clit. He looked up once to check that she had liked it, smirked with satisfaction when he saw her biting her lip, and went back to it.

His licking, it felt amazing, nothing at all like her first time in the janitor's closet with a clumsy nerd, when she'd peaked with frustration and picked the first guy she didn't think could reject her. Nothing even like the drunken hookup that one time who had sat back and let her do all the work. Trevor put all of his attention into making her feel good, searching out the spots that felt the best and listening for her quivering moans because just hearing her pleasured voice was satisfying in a way.

No wonder he liked Kate, who couldn't be bothered holding herself back even a little... Lydia thought she should make more noise; she'd be found out if she didn't squeal the way her sister did...

"R-right there!" she managed to cry when his tongue grazed her sensitive clit, prompting a barrage of swirling licks that made her knees buckle from the sheer enormity of the sensation. "Fu-uck, you're good at this~"

Trevor backed out and put his thumb to her, rubbing slowly but firmly further and further between her lips while she moaned above him. "That's my girl~ You feel like you're ready, aren't you?" He made his point by withdrawing his thumb and easily pressing in a couple of fingers with a faint squish, spread them inside her and curled them to caress her from within. "Go on, tell me what you want, what you crave. Who's my insatiable whore?"

Lydia gasped, knees trembling at his touch. She bent and grabbed the dresser to stabilize herself, unknowingly thrusting her ass back at Trevor and helping him plunge his fingers all the way in to the knuckle. She could have squealed, she felt lightheaded, but if it was going to happen anyway...

"I-I... I want you to fuck me..." she said weakly, almost unable to hear herself under the saxaphone.

"What's that?" He came up behind her, hugged her from behind and took her breasts in hand, the tip of his throbbing penis resting at the precipice of her vagina. It would only take the slightest of motions to pop himself in, but he was waiting for her okay even now, when she knew that her slut of a sister would have been plowing him for all he was worth for the last twenty minutes. "Come on~ Havin' the time of your life playing hard-to-get for once? Why don't you tell me you want to feel me knocking against your womb, or do you want to take it in your ass again? Am I not your hot meat dildo anymore?"

Right, Kate would have taken control by now.

"T-that's right, just don't move and I'll... take care of it."

"Whatever you want," he said with a kiss to the nape of her neck.

With a few deep breaths, she prepared herself and pushed her ass back, taking him halfway before losing the one she was holding. 'He's so fucking big!' she thought, feeling his thick meat stretching her out. No, he was probably average enough, but he was still the biggest she'd ever been with and every inch of his cock plunged into her hole felt like he would tear her apart if the two of them went all out.

"Virgin game again?" he said. "Okay, just hang on and I'll take care of the rest."

She didn't have time to ask what he meant by that, Kate would have known anyway; he hooked his arms beneath her armpits, laced his fingers together behind her head and thus pinned her in place such that the only move was to hang from the embrace and sink further onto his throbbing erection.

Her tits swayed, supported only by Kate's filmy lingerie, as good as nothing. The only saving grace was that Trevor couldn't see the agony on her face as he began moving his hips, working his cock into her by inch after sodden inch. The slow piston rubbed at her walls, the head of his cock felt as if it should be tenting her stomach with its slow prodding, but she couldn't move enough to look.

By the time her ass met his hips, her legs were barely holding her up; her thighs burned and her toes curled with agony. But she could take solace that he was all the way in, the tip of his cock only tickled the deepest part of her and she could hardly deny that her body was loving it. Her juices ran down her inner thighs and she could feel her heart going crazy. Heat and electric pleasure ran through her every limb from her aching legs to her useless, hanging arms.

"There we go, ready to start?"

'We haven't started yet!?'

She weakly nodded.

They hadn't started yet, that wasn't even the warmup. He pulled back nearly out of her, giving her a feeling of emptiness like she'd never felt before before thrusting the whole of his dick deeply within, nearly knocking against her cervix again, and he didn't stop there, continuing the rhythmic pounding slowly at first but more and more quickly with each thrust. It was only seconds before he was slapping ferociously against her from behind, his cock scraping at her insides, pounding her depths too quickly to recover from each one in time for the next. Lydia hung on for dear life, nearly limp from his hold on her, no longer caring about what kind of face she was making. She could have had her tongue hanging out and she wouldn't have had the capacity to acknowledge it; her whole focus was on the fullness and the friction and the sound of her juices slapping between them from below.

Orgasm was on the horizon one moment and the next pounced on her, coursing through her. She shook in his arms as he continued pounding, extending the feeling unnaturally. She felt as though she could ride the feeling of pleasure forever and never get tired, simply leaned back and enjoyed the eye-rolling orgasm for what it was. And once she'd finished after seconds that felt like minutes, Trevor pulled out and followed her on her descent as she crumpled to the floor. She smiled, twitching still at the barest feeling of air passing over her skin.

"That was amazing..." she said in the post-orgasm delirium.

"You say that like it's surprising." He scooped up her legs and lifted her without much effort, then brought her into her sister's bed, lifting the covers and sliding in with her, his arm around her shoulders. After everything that had come before, she was tempted to lay her head on his chest and drift off just like this, damn the consequences. "I love you, I want you to know that."

It was all for the act, she had to tell herself as she said, "I l-love you t-too..." She had to think how to get out of here and find some excuse that would get her off the hook, even if she had a few hours before Kate came home. More and more it felt like there was no way for her to get away from being found out.

Even if she somehow reaquired her identity out of sight, Trevor remembered having sex with Kate just like every other day... Maybe they wouldn't talk about it, it was something too common to remark upon, yeah, that was it.

"Trev, I've gotta-" she began her escape.

She was cut off by the phone ringing on the nightstand. "One sec, hon." He answered it, she couldn't hear who was on the other end. "Yeah? Yeah, she's with me right now... In bed... I know, right?... Well you'll have to hurry... Sure, I'll keep on keepin' on... Yeah, think it's about time too... Alright, bye." And the call ended.

"Who was it?" Lydia asked with a dry throat, panic chilling her.

"Hm? A friend, hope you don't mind I told her we were sleeping together."

"W-why would I?"

He clung to her, brought his lips to hers in a warm, affectionate kiss that lasted until her brain had fogged and her anxiety drifted away on the wind. And he took her in a hug, locking an arm like iron around her waist before saying, "Just so you know, Kate shaves."

Lydia made a sound that reminded her of a dying animal, didn't bother struggling to get out of his grip. There was nowhere to run, no lie to hide behind... there never had been... She felt like throwing up, like curling up inside herself and dying from the shame alone.

"Stay with me for a few minutes, okay? I promise it's not as bad at it seems right now."

She choked on her words, might have started bawling at any moment. "How could it not be? You bastard..."

He kissed her forehead, unfortunately his grip was too firm for her to to scratch at his eyes. "I gave you the chance to stop once I figured it out... only the first kiss was an accident."

They lay nearly motionless for several minutes in mutual embarrassment, but that all ended the instant they heard the front door close and the last party enter.

Kate appeared in the doorway of her own bedroom, a familiar sight from an unfamiliar angle, and came in while Lydia thrashed as best she could to at least get free and defend herself from whatever her sister was about to do.

She closed her eyes against her punishment, and was shocked by a kind hand stroking her hair from above. Teary eyes turned up to an angelic sight; she said, "I'm sorry... I didn't mean to... really..."

Kate sighed. "Trevor, let her up. I think it's time to have a talk. I got Chinese, so... yeah."

-

Lydia sat numbly with a serving of fried rice and broccoli beef growing cold in front of her. The other two were just eating quietly around the living room coffee table as if nothing untoward had just happened, as if Kate hadn't just walked in on her boyfriend and her sister, who was still only dressed in a titless bra and leaking said boyfriend's semen onto the couch. It was a second-hand couch anyway, though she didn't know how to feel about caring about stains at that point.

With an egg noodle hanging from her lips, Kate smiled across the table at Lydia and Trevor naturally wiped her cheek clean with his thumb.

It was too hard to take, Lydia didn't think she could swallow anything if she wanted to, the way she was twisted up inside. "Well? Aren't we going to talk about it? Two of us are naked and we're just supposed to eat like nothing's happened!?"

"Of course not," Kate said, "but I didn't think it would happen this fast. I'm still sorting out my thoughts."

"You saw this coming? If you knew he was such a cheating bastard, why is he still in our home?"

"It's not really cheating, you see..." Kate set her food down and approached, put herself firmly into Lydia's space and touched their foreheads together. "I need you to promise you'll listen to everything I'm about to say. Can you do that?"

Still mostly nude, anxious, with her sister in her lap, Lydia said, "I... guess I owe that to you..."

"Trevor and I are getting married."

"What!?"

"Hush... We're going in on a mortgage together, it's pretty serious. And when I thought about what that would mean for you and me, I almost considered calling it off entirely. No, don't say anything, I have to get this out all at once or I might not have the balls later... I love you. I always have loved you, and the feeling has only grown more deeply as we grew up together. When I think about the rest of my life, there's never been one future I wanted where you weren't by my side. And then... I thought that some man would eventually figure out how great you are, and I would be over here with Trevor, and you would leave to be with that lucky guy. Maybe it wouldn't happen all at once, but you would drift away from me and someday we would become like strangers to one another.

"You would have your husband, your kids, and I would have mine. They would take up all of our attention, soak up all of the love we have to give, and we would slowly forget one another. It wouldn't matter that we've been together for decades, the connection would be lost. It's not like I don't want you to have those things, I do, but I know how lonely I would be without you to come home to...

"So I told all of this to Trevor, and I had an idea. I said that if you two were close enough... maybe you could have all those same things alongside me. We're the same person, kinda; our daughters would be sisters, our sons would be brothers... I know it sounds crazy, of course it is, but that's just how love makes me..."

Lydia turned her head away from her sister's needful gaze and the sight of her... their... lover naked on the couch beside them. She choked on her words. "It's impossible, you know that... What would mom and dad say?"

"We can cross that bridge when we come to it." Kate took Lydia's hand in hers and interlaced their fingers. "I've thought about this for the longest time, you know? It's not like I don't have any plans. Don't you remember me trying to fold you in with my boyfriends in the past?"

"I... I thought you just wanted a threesome."

Kate shrugged. "That too, to a point." She kissed Lydia's cheek, snuggled her face into a naked shoulder. "I'm getting married, that's all there is to it. There won't be another chance like this one. If we can't make it work, it may not happen today or tomorrow, but soon we won't know each other anymore and that would tear me up inside. All I'm asking is that you give it a chance."

Lydia turned to Trevor, who teetered on the edge of his seat as the third wheel. "You were in on this the whole time?"

He nodded solemnly. "We were going to do a whole plan on your birthdays this year, but you know what happened in the bathroom. I figured I had a chance, since you didn't run away. I'm sorry to have tricked you like that, but it's not like I could have just come out and said anything; you would have bolted like a frightened animal and you know it... Not that it makes tricking you any better, I understand."

She replied, quietly, "I thought I was tricking you too... I can't hate you for any of this."

Kate repeated, "All I want is for you to give it a chance. Please, if you don't like it you can always walk away; I'll assume it wasn't meant to be. But... right now... I think you might owe me for cheating with my boyfriend?"

"I-" Lydia was caught, her thoughts dripped like warm syrup as she considered it, as she felt the warmth of her sister's embrace, remembered the gentle passion of her boyfriend. "I can't promise anything, after."

-

This was crazy, it felt like a dream and Lydia couldn't decide whether that meant nightmare. They'd finished eating casually enough for the situation, and of course not a one of them had any idea how embarrassed they should have been; some internal limiter had been passed by at a sprint and past that point was a kind of numbing emotionlessness and an acknowledgement of facts.

Kate produced a blindfold and put it on Lydia without a fight, then pushed her down onto the couch, naked and vulnerable as she was.

There was the sound of rustling clothes as Kate joined the other two in nudity, and her weight appeared over Lydia, pinning her to the couch.

Kate's breath was only inches away, hot and heavy. "This is your last chance to turn back... Can I start?"

Since Lydia felt she would have choked on her words, she only nodded.

A second later, she felt the plush sensation of her sister's lips descend onto her own. So, it wasn't only that she wanted them to share a man? Fine, whatever, after a day like this it might as well happen on top of the rest.

Lydia lay beneath her sister, reeling at the soft touches of skin on skin, the heat of Kate's body. It shouldn't feel good, she knew, but Kate's mellow kiss smoothed out anxiety from the darkness behind the blindfold. Unseen, Kate ran her hand from Lydia's collarbone, circled her breast, and came to rest on her hip as Kate's knee expressed itself between Lydia's thighs. She spread Lydia slightly, her lips surging with passion, used her hand to enhance a very slow, careful rocking motion that brought Lydia's butt off the couch cushion and rubbed her wetted lips along her sister's plump thigh.

The kiss progressed from passionate and loving to hungry, Kate's other hand holding Lydia's cheek so she couldn't turn her face away as Kate's lips parted and moans began passing between them. It wasn't as though Lydia meant to do it, but her tongue responded automatically, clumsily against her sister's patient, practiced movements.

Lydia clutched her hands to the cushion's edge, refusing to let herself get swept away when she knew damn well she should be repulsed, but wasn't. She was shaking, a strange fire growing within that she understood too well from her time listening with her ear against their shared wall, fingers in her sopping wet cunt...

She'd imagined it before, in the manner one thought of jumping at the edge of tall buildings. Her heart raced even now, as the terrifying scenario played out in real life, as her sister's fingers played across her skin in an effort to convince her to continue on in the same way. she wasn't even a lesbian, she hadn't thought, but the sensation of Kate's heavy, throbbing breasts pressing down against her own drove a desire she didn't dare follow to take them in hand.

Without sight, she could have imagined it was any girl doing these things, getting her motor running, that she was about to have a normal threesome, but it was undeniable that these moans belonged to her sister; she'd heard them so many times. And now she heard her own in response, the same sounds that she'd suppressed for years as she masturbated within earshot, unleashed now and mingling together with the emotion's source.

Lydia heard as Trevor circled to her side, slid his own strong hand between the two of them and Kate pulled up Lydia's butt so that he was caught between them, grinding between their most sensitive areas. He leaned in and kissed Lydia's belly while Kate ground herself against them both with big, circular hip motions.

"Does it feel good?" Kate broke their kiss to ask. "He's really good at fingering, you know. I know you've heard me cumming from it... I know you've been cumming on the other side for a while now."

"Ah-" Lydia couldn't answer for the emotional and physical overload she was going through. She'd know all that time, some of that time? Then why hadn't she said anything!?

"I used to tease my boyfriends, I know you know, with maybe having a threesome. Every time you shot it down but it was a real offer. I wanted it, I wanted this, I wanted to be this close to you."

Then Trevor stood, a heady scent following the trail of his hard cock through the air. Kate sucked it between her lips and down to the back of her throat mere inches above Lydia, began a deep, choking blowjob that was so much sexier for being unable to see it. Lydia imagined the way Trevor's cock would glisten with Kate's saliva as it plowed in and out of her mouth, the way it would run down Kate's chin and drip down to speckle Lydia's face. It didn't take long for her to feel the cool wetness of her sister's spit falling on her cheek, on her lip, and she mindlessly licked it up...

She was still moaning, her sister's pussy lips slipping and sliding against her own, her sister's soft curves hugging hers. she could almost see the shadow of Trevor's balls swinging as they slapped against Kate's chin at the edge of the blindfold. She'd never even given fellatio, but she fantasized about taking his balls into her mouth and savoring the flavor of his skin. She ended up opening her mouth...

And her fantasy was immediately realized, Trevor's smooth-shaven balls dragged along her cheek, across her lips. She took the opportunity to suck, popping one between her lips and swirling her tongue around it while she was still dizzy enough with lust to accept that she was doing it. Lydia heard the other two talking about it, urging her on, but she shut her ears to it, knowing that letting herself understand language at this point would drag her too close to reality for comfort.

Reluctantly, she let him pull back, her tongue lingering for a moment in the air as his testicle left. She was panting, the taste still on her tongue.

It wasn't over; Kate shifted her legs and Lydia let her, leaving herself to be manipulated however these two needed her to be. Kate spread both of their legs so that their pussies were pressed together and open. Right away it was clear why she'd done it; Trevor put himself behind them, slipped his big, hot cock between their wet lips, crossing their slits and bumping against firm clits erect and throbbing.

And Kate tore Lydia's blindfold off, hugging her closely to her own chest as Trevor began slamming himself between them, hips slapping against plump asses, cock squishing through slippery, tender flesh. With it all overwhelming her other senses, Lydia hardly cared in the moment that she was looking into her sister's pleasured face, chin wetted with spit; she thrust forward, pressing her lips to Kate's, ignoring the surprise on the other face.

This is what she wanted, wasn't it!? Lydia mashed their lips together, enveloped by lust, lazily played their tongues together as they moaned. Both sisters rocked with the force of Trevor's cock slamming between them, friction down between them like he was trying to start a fire, like he was fucking them both at the same time equally, like he loved them both equally in this moment.

Threefold moans quickened, interrupted by the impacts as they came more and more frequently. So this was what it was like watching Kate cumming... Lydia almost couldn't appreciate the way her sister's face loosened as she approached that point, she was getting there herself.

"That's it, baby, come for me!" Trevor slammed himself against them both until they trembled in orgasm around his cock, continued rubbing himself between them even as he exploded across Lydia's stomach, riding their twinned orgasms until all three were starved for breath and near collapsed into a three-way hug on a couch not really big enough for the embrace.

Lydia touched her belly, smelled the slippery liquid that came away on her fingers. She was glad for the shred of dignity she possessed to wipe herself clean against the couch instead of licking her hand clean.

Then Kate released herself from the hug and licked the rest of it off her stomach.

Minutes later or maybe hours, Lydia didn't know, the three of them had moved back into Kate's bedroom and Lydia lay sandwiched between the others in an embrace intended to soothe her.

"Our parents are going to disown us..." Lydia said eventually.

Kate kissed her naked shoulder. "Promise you won't be mad?"

"As if anything could affect me at this point... What?"

Kate reared up with a smile like sunshine, shimmied up to Lydia's ear, and whispered, "I told them this plan literally like a decade ago."

"You what!?" Lydia struggled to adhere to her promised calm.

"Dad was actually okay with it from the start. 'Not like you two can get each other pregnant anyway,' he said. Mom was harder to convince, but I said if I couldn't have her blessing then I was going to swear off men altogether so there wouldn't be any grandbabies. Took longer than I thought, too, to find a guy who wasn't just into it for the fantasy threesome. Mostly they left when I told them what I really wanted."

Trevor piped up, "Lot to dump on a guy right out the gate, after all."

"We were going to take you to the beach with us next month and try to get you super drunk, then catch you in the act when you started touching yourself in the next room," Kate said with a sigh at the fact that all of her planning had to go out the window. "But I guess this also works, if it works."

Lydia laid back, stared at the ceiling even while gentle sax continued to play in the background. The playlist must have looped five or six times since Trevor put it on, but nobody felt like getting up into the cold to turn it off.

She sighed. "Is there anyone you haven't told about this?"

Kate paused in thought. "... You?..."

It was all too convenient, felt like a dream, but the next morning she was welcomed to wakefulness by a un-sisterly kiss and came out to an un-brother-in-law-ly kiss in the kitchen. How the future played out, she ignored the thought while basking in the present. At the very least, she would never have to ignore her sister's lusty moaning again.
