His balls were already starting to swell again. What was a single cumming to a potent young man under these circumstances.

But then Bunny got to her feet on shaky legs. She grinned at her brother, showing him that she had no regrets or misgivings. But then she stepped back. Bunny was seething with desire and she was afraid that if she stayed in the room with him she was not going to be able to control her unholy urges.

The girl was yearning to suck his prick and let him shove it up her cunt – but her inhibitions were still clinging in her conscience, telling her it was taboo.

She knew that she had better leave before she succumbed to her raging lust – to give herself another hand-job in privacy and relieve the desperate pressure.

"That was fun," she said, giving him a wink – trying to make light of the situation and conceal the raging turmoil of her emotions.

"Anytime you wanna do it again!" he rasped.

She was backing away step by step. "Yeah – well, you can cream my tits again, sometime – but now I better take a shower," she said. She grinned. "We don't want Mom and Dad to see me with spunky tits."

She hesitated, then turned and left the room, her ass swinging provocatively in her sheer nightie.

Jack watched her go, grinning.

He had often had naughty fantasies about his sexy kid sister while he was beating his meat but he had never expected anything to happen between them.

Now the horny boy was wondering just how hot Bunny was – and if she would be game for more than a tit splashing.

He sure hoped so.

He didn't suppose that she would let him actually fuck her, but maybe the next time she would jerk him off and let him give her a fingerfucking, at least.

His cock was hard as a stone again and he could feel another cum load seeping, drop by drop, into his balls.

Bunny was going to take a shower.
