close, the cool air from the fridge brushing his face and arms, until Kasey turned her head and looked at him from the corner of her eye. Her body didn't move. After a second, the smile that annoying siblings give one another faded from her face, replaced by a nervous frown, which turned into an earnest, thirsting look that glittered from deep in Kasey's eyes.
Jon put his hand right where she had forced him to put it in his dream, and kissed the side of her head, slowly. Kasey turned to face him, never breaking eye contact, and wrapped her arms around Jon's neck. Seeming unsure and still a little confused, she leaned her face into his, hesitated, then pulled back again, never looking away. Jon pressed her waist into his, and just barely touched his lips to hers. She closed her eyes, and Jon felt her lips loosen and open to his next kiss. Soon Kasey slid her tongue down his throat, and pulled herself closer, almost clinging to him. He felt her erect nipples brush against his chest, and put his hand on the lower part of her ass. She gave a light moan into his mouth, and he pulled her away from the fridge.
A desperate whirlwind of caresses carried them as if by some higher power to their parent's bedroom. By the time they knocked the door open and whirled into the king-sized luxury bed, their "caresses" were verging on instinctual, animal humping. They were completely lost in their heat, forgetting so many of the rules, morals, and proper manners they had been taught, side by side, to follow. All they knew was that they were two bodies, two cherries on one stem, and not even the combined forces of the whole nosy neighborhood could pry them apart now.
Kasey fell hard on the bed, with Jon pinning her into a kiss. She fumbled to undo the button on her shorts, and Jon tugged them off her waist, lifting her lower half clean off the bed in the frantic struggle. Kasey was almost startled by the speed of things, but it only made her yank off her tank top faster. Her hair was fanned out from her head in trailing bunches, and her eyes were frozen wide with anticipation as Jon kicked off his pants and pulled his shirt over his head.
Things seemed to enter a different gear once Jon's cock hung over Kasey's trim little bush. He wrapped his hands under her lower back and pulled, so her torso curved up in the middle towards his heaving chest. Her full breasts rose and fell as she panted like a gazelle in the jaws of a lion. Jon leaned his face close to hers, pretending to move in for a kiss, but then swerving down to give her a tender bite on her neck instead. Almost at the same time, he slid his cock between her legs, which unfolded wide to let him in. As soon as Jon felt his tip slide in, he pulled away from her neck, looked into his sister's eyes, and thrust balls deep into the hot chamber between her hips. Kasey's face froze in a silent gasp, her eyes locked on Jon's, as he began to pump into her.
Jon slid his right hand under her ass, and slipped his middle finger into her tight asshole, that was already covered in her pussy juice. He watched Kasey's face as a warm liquid seemed to break in slow motion over it. Her frozen gasp and wide eyes got even bigger, then released like a crashing wave into a deep, guttural moan that twisted her mouth sideways and had her eyes turned up to the baseboard of their parent's bed. If there had been any trace of civility left in her supple body at this point, it was gone now. They were in great danger, each blind and ravenous for the flesh of the other, with Jon stuffing Kasey's pussy in wild abandon, and Kasey holding on to Jon's back with slipping, jolting fingers. An old framed photograph of their grandfather, looking sternly towards the camera, shook off the wall, fell between the bed and the wall, and shattered. At that moment Kasey came, neck curved back inhumanly, her hair a mess of tangles that she might never brush out. Jon gave a few final powerful thrusts, holding his finger deep in her ass, with his other hand plying her breast, and shot his load into his little sister's waiting pussy, while her legs still trembled uncontrollably in her waves of climax.
Jon pulled out only when he was sure the very last drop had spurted deep into Kasey, and he fell to her side, among the disturbed waves of their parent's thick bed-cover. Jon turned to Kasey and pulled her towards his chest, with an arm around her, but she was still delirious, her gorgeous face surrounded by a mess of chestnut hair, her long, strong legs wet to her mid-thigh with their sex, and her breasts rising and falling with her finally satisfied breathing. There was no telling how long this had been building up between them, Jon thought as he watched Kasey's eyes open to his again. She gave him a loving smile, and weakly tugged him back on top of her for round two.
"Again?" Jon said with a smirk, already on top of her.
"Y-yeah. And this time, call me Kay-Kay, like you used to." Kasey said shyly. Jon's only response was to brace himself for another wild ride.
