🔞🔞18++( Big sister wants a roommate, brother has some conditions.)
When Allie emerged from the bathroom in her pink robe, she went to start the washer. Kyle got up and returned to the bathroom to brush his teeth. Outside, Allie was cussing, pissed about not knowing which box had the laundry detergent. Brush, rinse, spit. Mouthwash, swirl, spit. Drying his mouth, Kyle knew his sister had found the detergent when he heard the machine start to fill. Allie walked past him toward the bedroom as he started to exit the bathroom. He mused over how the night would play out as he walked into the bedroom and closed the door behind him.
As if he wasn't even there, Allie walked over to her dresser, dropped the robe to the floor and, totally naked, opened one of the drawers, bent forward and began rummaging around for a pair of panties. Kyle gawked at the magnificent view of his sister's ass and side-boob. His mind was resolved in an instant and he walked purposefully toward her.
"Normally," Allie began, "I don't sleep with anything on, but since we're... Oh! "
Close behind her, Kyle lined up his cock at her pussy's entrance, reached around to hold her lower abdomen, and thrust forward, burying the first few inches inside her.
"Kyle!" she yelled in disbelief. "I'm your sister! What're you doing? We can't do this!"
Unheeding, he began to pump himself deeper and deeper into his sister's moist cunt while reaching around with his free hand to grab her right tit. Allie tried to push his hand away while also trying to dislodge her brother's cast iron dick from her pussy, both efforts ending in failure. Once his cock was fully seated in her, Allie sobbed and seemed to come to grips with the reality of what was happening.
"Kyle," she said softly, her voice more a lamentation than an objection, "honey, we can't do this. Please, we need to stop." Kyle pressed hard against her, pushed her firmly against the dresser. His left hand went around to control her face, pushing her head to the right so he could look into her eyes. His right hand reached even further around to take hold of her left breast, pinching her hard nipple. He pushed upward with his hips, driving his cock as deep as it would go, lifting Allie up on her tiptoes. Allie moaned, not from pain but from the delicious pressure inside her, pulsing, throbbing with her brother's every heartbeat.
"My beautiful, amazing sister," Kyle whispered calmly into her ear, "I have decided to accept your offer. It comes with a few conditions." Kyle pulled his cock back, almost clear of her cunny, then rammed it back in hard.
"U-u-n-hhhh! Kyle..."
"First, though, we are going to fuck. All night. This is to break the ice so we can move forward without any hesitation or nonsense."
"But, we..."
"Sshhh! Listen! When we move in together, we are fully committed to each other and to our studies. No socializing, no parties, no dating. We are young and the whole hormone thing means we're going to be horny as fuck most of the time, but outside relationships mean less focus on school. Allison, I love you more than any other person in this world, and I know you love me, too." Kyle eased up on pressing her against the dresser and began to slow fuck her, pulling halfway out and slowly sliding all the way back in.
"We will take care of each other's needs, whenever it's needed. No outside distractions, no romances. We'll share the expenses like you said, share the housework, and anything else. We're both going to need sex and it's stupid to pretend otherwise. You need to be fucked? I'll fuck you. Need your pussy eaten? I'm here for it. Just be here for me in the same way."
A softness seemed to overcome Allie's body, a gentle acceptance. She leaned forward, laying across her dresser and pushing her hips back slightly to a more accommodating angle. She trembled.
"The rent is six-hundred," she breathed softly. "I already paid for this month."
Understanding that his conditions had been accepted, Kyle placed both hands on her hips and began to fuck his sister like a porn star. With every thrust he felt his balls slapping his sister's labia and clit. Her pussy was soaked and he was euphoric, loving her tightness, her wet heat. It wasn't long and her sex noises began to increase in their urgency.
"Fuck, Kyle, I'm close!" Kyle reached out and took a handful of her hair, tugged back on it while slapping her jiggling ass cheek.
"G-o-d-d-aaaaaammmn! Oooh fuck! I'm cumming! Fuck, gimme that dick!"
Spurred by his sister's outburst of passion, Kyle redoubled his efforts, slam-fucking his sister at full throttle. Her cries of pleasure filled the small bedroom. The dresser banged repeatedly against the wall with his every thrust. Neither cared if the neighbors heard them or not. Their screwing would not relent while there was still energy to continue.
"Fuck, Allie, your pussy feels so damn good!" Again and again, Allie was racked by fierce orgasms, crashing through her like waves as her brother pistoned his cock inside her. When she felt she could endure no more, she reached back to push him away.
"Kyle! I can't take any more, I'm too sensitive down there. We need to stop for a minute." Kyle pulled out of her, caught her by both arms and quickly moved her to the bed. He shoved her onto her back and hastily crawled in between her quivering legs. Without warning, Kyle buried his face in her twat, sucking her overstimulated clit hard into his mouth. Allie screamed and bucked her hips, trying to dislodge herself from the marauding tongue that was assaulting her. Kyle wrapped his arms around her hips and forced her ass back down to the mattress.
"Kyle, fuck! It's too much! I can't... aahhh-eeeee!!! " Allie came hard into her brother's mouth, which only served to drive him on. She knew he wasn't about to ease up and resigned herself to her fate, giving herself completely to Kyle's desire for her flesh. She stopped resisting, stopped trying to escape the mouth and tongue that were ravaging her sex. For nearly half-an-hour, Kyle feasted on his sister's cunt, greedily swallowing the sweet nectar that flowed copiously from her pussy. No longer vocal, she could only gasp and whimper as ecstasy coursed through her, threatened her sanity.
Twice, she lapsed from consciousness, only to snap back as the next wave struck her. Shaking violently and semi-conscious, she was only vaguely aware that Kyle had moved up her body and was lifting her legs. She was just realizing the shift when she felt her brother's fat, iron dick penetrate her steamy wet cunt, buried to its full depth in a single, savage thrust. She tried to cry out but only managed a hoarse squeak.
Kyle leaned down to her, kissed her not like a brother but like a lover on fire. He burned for her, needed her more than oxygen. For a long while, they lay there like that, Kyle's cock deep inside her as their lips and tongues made love. His hands explored her beautiful titties, had their way with them, with her erect nipples. When he could hold back no longer, Kyle began to fuck her, slowly at first, savoring the feel of her tight pussy muscles, like rings, squeezing against his shaft. The big mushroom head of his cock scraped against the walls of her cunt like a squeegee, in and out, in and out in such a delicious rhythm.
Taking his sister like this, gazing down at her incredible body as his dick pumped relentlessly inside her, seeing her tits bouncing with every thrust, was the greatest moment he had ever experienced. He didn't want the moment to ever end, wanted to fuck her in every position imaginable. For this first time, though, he wanted to cum inside her like this, in the missionary position, watching her eyes as he poured himself into her, gazing into her very soul as he gave his to her. In that moment, Kyle knew that he would never love another woman as much as he loved Allie.
As Kyle's first orgasm of the night struck him, he cried out against its fury. Pumping hard and fast, he felt the heavy load blast through his pulsing shaft, stream after thick stream, felt it leave his body and enter his sister's. Allie felt it, too. Her eyes opened wide in shock, only to see Kyle's, inches from her own, staring at her with a love and passion she had never known. Over and over, his thrusts never waned as his hot, slippery cream flooded her pussy. She was terrified and insanely aroused at the same time.
A powerful mix of emotions waged war inside her, her mind a smoking battlefield. She loved what was happening and hated it at the same time. She wished it hadn't happened while simultaneously wishing it would never end. Was this to be her life for the next few years? What about after college? Would she want to ever give this up? As Kyle collapsed on top of her, lungs desperate for air, mingling his sweat with hers, Allie wrapped her arms around her brother and kissed his neck. She knew her answer, knew what she wanted.
"Oh, hell," she mused, "I'm probably going to have to go for a PhD."
