The Last Temptation of Lisa

Cock in hand, Brandon looked down at his twin sister’s pussy, so wet and inviting and completely exposed as she begged him to fuck her in front of Lisa and Kurt. He tried to remember how many times he’d already been inside her, his sister. How many times had they already crossed this taboo line? How many times in the car? On the way to the campsite? Before lunch? After? At some point they’d tried anal and been caught by Kurt. How many times between then and now? Before this week Brandon wouldn’t never have seriously thought about his sister sexually and now he couldn’t remember a time without, couldn’t imagine not having his cock inside his sister.

Brandon’s mind was a blur of incestuous experimentation independent of time and space…and even after all that, Lisa’s words had penetrated to the heart of matter and made him doubt what he was doing. Of course, he should doubt what he was doing. No one should cross these lines in the sand without considering the consequences. And nothing good could come from this, he knew. No happy ever after for the sick siblings who camped out for a week in a forest just so they could fuck in peace. But Brandon was weak. Even knowing that, know how wrong, how destructive, this single act of fucking his sister would be…Brandon couldn’t stop himself.

‘How could any man?’ he asked himself as he looked upon his sister, half bent over in front of him, pushing out her ass to him, that pretty, wet little clam of hers dripping between her legs. She looked over her shoulder at him, her long, sweaty hair pulled over the other side, leaving her neck bare. Smooth and unblemished, Brandon felt like a vampire, desiring to sink his teeth into her succulent skin. She locked eyes with his, hungry eyes, **** to feel her brother’s cock deep inside again. Eager to show Lisa how good he could make her feel. How could any man look upon this woman, blood or not, and not be willing to give up the world for her?

His mind set, Brandon rubbed the head of his cock against her pussy lips, her cunt drooling faster as his bulbous tip pried her labia apart. He found her entrance and with a gentle push of his hips, slid his cockhead inside his sister’s puss. Her eyelids fluttered, head hanging low as she let out a long sigh, whispering joyous adulation at simply feeling her brother’s cock entering her for the umpteenth time that day. With his cockhead snug inside her pussy, Brandon’s hands moved to her hips and pulled her back on his cock, simultaneously thrusting forward. Madison’s sigh turned to a deep, low moan as, in one long, slow motion, Brandon’s cock was buried fully within her cunt.

Amidst her pleasure, Madison looked to Lisa and smiled to see that her Latina friend had watched the whole thing. Her eyes were wide with shock and her hands covered her gaping mouth, but she had watched, just as Madison had hoped. That meant no matter how wrong or unlawful Lisa thought their union to be, she was mesmerised by it. Seeing brother fucking sister interested her, thrilled her. Eyes on Lisa, she felt Brandon pick up the pace, still fucking her pussy with long strokes but faster now, harder, his hips slapping against the flesh of her ass.

“Ah, yes, fuck me Brandon, brother, just like that, fuck your sister just like that, nice and hard and fast and good,” Madison moaned, glancing back at her brother as she grabbed onto his arm for support, to keep his hard thrusts from knocking her off her feet. “My brother’s dick feels sooo good inside my pussy. So full, so hot.”

Madison heard Lisa gasp from behind her hands. Though Madison knew that he friend was no prude, hearing a sister dirty talk to her brother like that must have been a real shock to her. Less surprising was Kurt who was openly watching the pair, squeezing at his cock through his shorts. Madison bit her lip thinking of more ways to coax Lisa out of her lawfulness.

“Uh, uh, fuck yes, keep fucking me, Brandon. Fuck me while Kurt and Lisa watch,” Madison encouraged her brother, not that he needed it, but he responded by gripping her waist tight and slamming into her with even more ****. “Ah, umph, shit, yeah, let them see your hard cock railing my tight, little cunt. You guys like what you see?”

“Fuck yeah, you guys are so hot,” Kurt declared, stroking his cock through his shorts. Lisa refused to say a word, and just stared, startled like deer in the headlights at being asked to weigh in on the situation.

“Better than last time?” Madison asked Kurt, between pants as Brandon ploughed into her from behind. “Better than when you saw him fuck my little asshole? That was the first time anyone’s ever fucked my ass you know. My brother will forever be the first man to stick his cock in my butt.”

Lisa’s eyes widened further, if that was possible. Though the Latina had suspected that the siblings had been out here for a while, fornicating in the wild, it shocked her to have it made real to her, to have the imagery of Madison bent over, ass in the air, Brandon’s cock sawing in and out of her asshole just as it was to her pussy now. She felt a warmth spread throughout her body, pulsing from her pussy, dampening her panties.

“Oh, shit, Madison, this is so much hotter,” Kurt replied, a shiver running through his body as his cock ached to be free. “I wouldn’t have believed it if I hadn’t seen it for myself but this is absolutely hotter than when I caught Brandon fucking your ass.”

“Yeah, Brandon fucked my ass. So, that’s sodomy on top of ****, right?” Madison said to Lisa, then back to Kurt, “You couldn’t tear your eyes away then either. But I don’t care who saw me then or who sees me know. I love my brother and I love his cock inside me.”

She reached back and pulled Brandon’s face to hers, meeting in a loud, wet kiss while he continued to ram his cock into her cunt. Harder and harder, building faster with each thrust into his sister’s pussy, feeling her own arousal leaking over his cock, making it even easier to fuck her as hard and fast as he needed. He could feel it rising in both of them, to cum, to climax with the other.

Breaking the kiss, Madison looked to Kurt, “You can take it out if you want. Touch your cock to the sight of us fucking, jerk it to this sister being fucked by her brother.”

The older blonde teen didn’t need to be told twice, shoving his shorts down to his feet in seconds and taking his hard shaft in his fist. Madison was surprised to see that it was longer and thicker than her brother’s. But it wasn’t Brandon’s. As nice as that big cock looked jutting out from Kurt’s well-toned body, it just didn’t set her insides alight the way that seeing Brandon’s cock did. Even still, with the fog of lust clouding her mind, she couldn’t help but wonder if a bigger, thicker cock really would feel any better.

While Kurt pumped his cock, Madison licked her lips, imagining the possibilities and glanced towards Lisa. A smirk formed on her face as she saw that the Latina’s hands had dropped from her mouth, her shock turned to a conflicted hunger as her hands fidgeted against her crotch through her yellow summer dress.

“NO!” Madison shouted pointedly towards Lisa, so abruptly amidst her breathy pants, the groaning from the boys and the rhythmic slapping of Brandon’s flesh against hers, that it made the other three teens jump. “YOU don’t get to touch yourself. Not until you can admit how hot this is. How right this is.”

“I…” Lisa murmured, clasping one hand in the other, holding herself back from going any further. “I…can’t.”

“Then no touching for you,” Madison insisted, then looking to Kurt again and waving with a finger. “But you can come closer.”

Nervous and unsure what to expect, Kurt did as he was told, shuffling closer to the dark haired cheerleader, looking towards Brandon for confirmation that a beatdown wasn’t on its way. The brother simply shrugged as he continued to pound his sister’s pussy with his cock. He didn’t get upset even as Kurt stopped in front of Madison and his sister reached out, trailing her fingers up along the underside of the blonde teen’s fat dick.

“You don’t mind if I let Kurt play with us for a bit, do you Brandon?” Madison cooed, taking Kurt’s cock fully in hand as she looked back towards her brother. “No matter what, I belong to you. I am yours.”

“Play on, sis, if that’s what makes you happy,” Brandon agreed, continuing to fuck her all the while. In his mind there was a flash of jealousy, that another man would be intimate with his sister, with his…girlfriend. But he also realised that Madison was young. It only made sense that she would be interested in other men and other cocks at this stage in her life. There was nothing really intimate about it, just cold, hard curiosity. Besides, what right did he, her brother, really have to be upset about his sister’s sex life? He shouldn’t even be fucking her, never mind sharing her.

But fuck her he did, thrusting his cock balls deep into her cunt with every pump of his hips, while he watched his sister bend over and lick Kurt’s cock from root to tip. With a small hand around his shaft, she stroked his length and at the same time wrapped her mouth around the head. Above her Kurt groaned, leaning his head back like a wolf howling at the moon. Watching the siblings fuck, denying himself any release until Madison had allowed it, had his cock so hard and on edge. With Madison’s cool hand against his burning cock flesh and her lips gently sucking on his tip, her tongue flicking along his slit, Kurt didn’t think he could be able to last much longer.

Pulling her mouth from his cock with a wet pop, Madison looked back to Lisa, seeing that her hands had returned to her crotch, pressing in against her mound through the fabric of her dress, and she smiled to see that her friend was struggling between her rationale and her desire.

“See how Kurt doesn’t care about how incestuous this is?” Madison said, locking eyes with Lisa. “See how he’s even willing to join in, that’s how much he doesn’t care about how wrong or unlawful it is. He sees it for what it is; a pair of hot people showing their love and affection, connecting on a level deeper than anything else in this world.”

“It is…” Lisa began, biting her lip as she watched Brandon’s cock slide into Madison’s slopping wet pussy, while her friend’s hand stroked Kurt’s cock on the other side. “This is so bad. I…I don’t know.”

“You do know, you just don’t want to admit it to yourself,” Madison challenged her. “If you didn’t think this was hot, you wouldn’t have stayed. You wouldn’t have watched. You wouldn’t be struggling with touching yourself right now as we speak.”

Lisa’s hand recoiled away from her steaming hot pussy that she’d been toying with through her dress and closed her eyes. She tried to concentrate through the overwhelming pressure of her desire and the erotic scene around her. She tried to clear her mind, to block out the sighs and moans and wet slaps of flesh on flesh. She had to think.

“I don’t mind. I want you to touch yourself, to release all that tension you’ve built up pining after Zack and holding yourself back. I want you to be able to give yourself over to pleasure and desire,” Madison prompted, a cock in one hand and another in her cunt. “All you have to do is admit how hot this is, how hot we are, brother and sister, fucking.”

Madison’s words embedded themselves in Lisa’s mind. Even in the darkness with her eyes closed all she could see were the twins, joined by his cock sliding into her puss. She opened her eyes and saw the same sight, joined by Kurt, his thick, naked cock in Madison’s fist. And as she looked upon them, a tremor ran throughout her body, a bolt of erotic anticipation firing off from her own pussy and spreading through the rest of her being. With a **** breathlessness, Lisa opened her mouth to speak.
