When her brother kissed her on the mouth, Robyn was so shocked that she didn't even try to make him stop. Her green eyes went wide and she made a soft, weak sound in her throat. The second time her, brother kissed her, a rippling wave of thrills went through her belly and seemed to spread along the exposed, swollen flesh of her pussy.

Kissing her very own brother? It was unheard of. She'd never even thought of doing it. But, now that it had happened, the soft, wetness of his caress was making her tremble. When he kissed her the third time, she went all buttery inside and her lips parted. Doug pushed his tongue between her teeth.

"Mmmmmhhhuuhhh!" she gasped, feeling his cock against her thigh. He rubbed it there, his hands touching her small waist, sliding toward her tits. She struggled weakly, but couldn't seem to make herself react in time. She couldn't think clearly. The swirling pleasure was taking her breath away.

"You're soft!" Doug breathed. "And so warm."

"Doug, don't do anything else. Let me up now."

He was kissing her ear and the thrills went down her back like high voltage. Robyn babbled something and tried to push her brother away. His cock had slipped upward until she could feel the head throbbing against one lip of her cunt. Doug squirmed around until her pussy-lips parted and the slick head brushed against her smooth, inner flesh. It was a silky, sexy feeling and for a moment, Robyn forgot what was happening.

"Ohhhhh!"

Even though she knew it was wrong, she couldn't help but squirm. The squirming made her folds open even wider, letting the head of her brother's cock slide between her silken cunt-lips. Robyn dug her nails into his back and panted.
