Punishing the Brats

Zach looked downwards, as if he were sheepish and she totally had him pegged. He nodded, and remembered the day before when he’d seen Sylvia on the gymnastic floor, moving with such fluid grace.

Just like how she should be moving atop his cock before their aunt stopped by, unannounced.

“Just keep that in mind, okay?” she said as he escorted her back to the front door, with one final inspection around the place. “And make sure you call your parents, I don’t want to hear from them all worried again. They’re supposed to be relaxing. And I’ve got work to do,” she added on wryly, reaching out to give him a pat on the chest.

“Look after Sylvia now, like a good big brother,” she said.

“I will,” he promised, and he was worried for a second she’d find another reason to linger. The soft scent of sex in the air was still strong to him, and his nostrils flared, needing it more than anything else in the world. How long had Aunt Betty been there? Half hour? Longer?

What the fuck was Sylvia doing upstairs?

Aunt Betty left and got in her car, and Zach forced himself to wait to make sure she was gone completely as he locked the door and felt his mind wander back to Sylvia. Hell, it’d hardly ever been torn away for more than a second. The whole time his aunt was there, his dick had been throbbing in his pants dangerously, at the thought of his little sister and all they’d do. Would do.

When at last, she pulled out of the driveway he turned and made his way back to the stairs. He didn’t mean to run, just hurry, but run was the only way to describe the bounds he made up those stairs, barreling towards Sylvia’s room.

It was quiet, though the light was on. Zach stood there for a few moments, listening, but there was only silence on the other end.

His heart was pounding, and he didn’t know what he was expecting to hear. The sound of her pleasuring herself?

What else could she have been doing up here as he had to deal with their aunt?

He placed his hand on the doorknob, turning it slowly. He held his breath as he pushed the door inwards a crack and looked to her bed.

There was his step-sister, still half undressed, her hand cupping her sex. Her breath rose in an even cadence, and his brows furrowed.

Was she asleep?

Zach looked her over, her top still pulled up and her breasts exposed from beneath her turtleneck. It didn’t seem like she’d even bothered to pull on her pants, and they lay on the floor at the foot of her bed.

He crept in, closing the door softly behind him, but she didn’t jolt or startle at all.

His breathing increased. She looked so vulnerable. His eyes trailed her lean body, over her toned thighs and along the flat of her belly. She had a gymnast’s body, of course, and he never really took the time to appreciate just what that meant.

He’d always teased her for her flat chest, but looking at the sweet, perky things topped with those stiff little nipples was making his cock throb in his pants. She always looked like her nips were a little hard, even as she slumbered.

She made a soft moan and shifted, and for a second he thought she might’ve woken up, but she simply adjusted herself and pet her little pussy before stilling once more.

He walked in a few steps, watching her intently. The way her ribs poked through a little, and he w

atched as they rose and fell with her slumbering breath. He was throbbing harder as he neared her.

She was totally at his mercy.

Even more than when she’d been begging for him to spear her and take her virginity. He’d been so damn close.

But he knew that if he touched her, she’d wake up. And if she woke up, maybe she’d change her mind.

Unless she woke up in the right mood, he reasoned. So he started to strip off his clothes again, tearing away that shirt to reveal his rock hard pecs and abs, those thick muscles bulging hard and delightfully tanned. He tossed his top to the floor of her bedroom, then hooked his thumb into his jeans as he undid the zipper. They were gone in a couple swift motions, letting that thick, veiny shaft spring out, standing out at attention before him as his heavy sac dangled beneath him.

He closed the distance between them and could smell her scent so heavy in the air. She smelled so damn sweet. He leaned down, settling his heavy body on the foot of the bed, waiting in stillness for her to readjust.

And just as she did, her legs parted and he could smell her even more, and he leaned in, inhaling that scent.

He’d watched her get off, she’d given him a blow job, and he’d made her cum. But now, sitting there and watching her sleep, all he wanted to do was taste her. To make her wake up, feeling so pleasured and horny that she couldn’t do anything but jump his bone and ride him raw.

After all, there was a chance she’d changed her mind. That she’d gotten frightened off by almost getting caught and now wouldn’t want to go all the way. But with his face in her pussy?
