Wearing her out

Clair pulled the plastic penis out of her pussy with a shlorping sound giving testament to how wet she was, throwing it onto her desk without a care to how much pussy juice it was coated in, and got up and hopped over to the bed, sitting on her knees next to him, her legs spread under her. It suddenly occurred to Matt that there was only one bed, but before that thought got much farther, Clair pulled him over by his shoulders, somehow stripping his shirt off in the process, and swung over him, her cunt stopping just above his face, giving him a close up view of what he had been looking at for the last half hour. As Matt looked up at her pussy, trying to work up the nerve to do what she was obviously offering to let him do, Clair stripped off his pants, forcing him to raise his legs so she could take them all the way off, and then reversed herself so her cunt was just above his dick and they were face to face.

Matt's conscience kicked back in again. "Um Clair, are you sure?" he began, but she reached down and pulled off her t-shirt, and Matt's protest died as he got an eyeful of a perfect pair of breasts in a powder blue bra. She reach back and unhooked it, gently cupping herself and slowly pulling the bra away to create a perfect boob drop moment. Matt, being a techhead, had of course seen a ton of boobs online, but 90% of them were fake, and none of them were a few inches from his face and showing no sign of sagging.

"All right, now, just give me sec to get settled," she said, reaching down to grab his dick again. She pulled him upwards a bit, and Matt felt something warm and wet brush across the tip. His eyes jerked down, past her full, firm breasts and their hard nipples and to where his cock was pressed against her moist gates, gripped lightly but firmly in her hand as she aimed him.

"Wait, I mean..." Matt began, but then Clair took her weight off of her legs. With one clean motion, Matt's dick was suddenly in a tight, hot space, and the sudden change drove him over the edge, hard. He bucked up at her instinctively, feeling his cum shoot into her. She fell forward onto him, rubbing her tits across his chest for a second. Not caring that he had just cum, she pushed herself back upright and began to buck up and down on his cock, which had softened not an iota, riding him hard right from the start. "So that must have been some ride," she said conversationally, only her slightly fast breathing to indicate she was thrusting up and down on his hard dick. "I don't think I have ever seen you so tense." As Matt came back from his orgasmic high, he was momentarily embarrassed at having cum immediately, but then the sensation of his sister gripping him with her inner muscles drove all logical thought from his brain and his hips started bucking up to meet her thrusts instinctively. "Too tired to talk? Ok, then let's just get ready for bed," she added when he didn't say anything. She leaned backward, arching herself to show off her firm swaying breasts. She let out a moan and began to really pound him, grunting with each thrust.

The sensation was so good. In that moment he didn't care that she was his sister, didn't care that he had just cum in her, that she was moaning and shrieking like a banshee and screaming out his name loud enough that he was sure all the neighborhood could hear her. The thought of his parents fucking on the couch and of his sisters eating each other out all went away to be replaced with the singular need to fuck her as hard and as long as he could. Never in all of his wandering around the internet and reading and watching porn had he ever thought that sex would feel this good. He was vaguely aware of the pair of them switching to doggy style at some point, the different angle bring a pleasant variation to the feeling as now he controlled the motion, thrusting into and out of her, his hands on her hanging tits kneading and squeezing, her hard nipples two hot points in his hands. He came into her again, hard, pulling her into him and pushing into her as hard as he could before he pulled back and moved to holding her waist, slamming into her again, his mind awash with pleasure as she frantically pushed back at his hard thrusts as he came, her own voice shrieking out as she orgasmed as well. Matt fell back on the bed, and Clair shifted with him, never letting his dick leave her pussy. She lay down on top of him, his dick bending pleasantly up into her cunt from behind, grinding her ass into him as they fucked, slowly this time.

At last they came again, more quietly this time, and Matt drifted off to sleep before he realized it. Clair, laying on top of him, her cunt leaking a copious amount of their combined fluids, joined him in sleep a minute later. Matt's still hard dick remained speared into her pussy as the lights went out.
