"Okay, okay," Bud said, rolling onto his stomach and wiggling between her parted thighs. Julie bent her knees sharply and her plump cunt-lips parted. Between the blonde curls, Robyn saw the glistening pink flesh. Bud held her pussy-lips even wider with his thumbs and pushed his mouth between them.
"Ohh!" Julie sighed, her slim hips rocking. "Ohhhh, do it just like that! You know how I love you to lick me, Bud!"
Robyn was in shock. Her mouth was dry and she was breathing harder than ever. Was this really happening? Was she watching her best friend doing the same thing she'd done just a while before with Doug? Robyn tried to leave, but she was frozen to the spot. She was enjoying it!
"You're wet enough," Bud said, lifting himself up over his blonde sister's body. "You're wet enough to fuck."
CHAPTER THREE
Julie opened her knees wider, exposing all of the pink flesh between the plump glistening lips of her pussy. Bud's cock swung heavily as he crawled forward. He bent his head to lick each of his sister's nipples while she arched her back and tried to press them upward for him.
"Don't forget the rubber," she moaned.
"Oh, yeah. That damned thing!"
Reaching over to the table beside the bed, Bud grabbed a small foil packet and tore it in half. Robyn could see the doughnut-shaped rubber as he pushed it over the head of his cock and unrolled it down the full length of his rigid shaft. The membrane was so thin that Robyn could see his cock easily through it. Julie worked her ass around on the bed like she could hardly wait for the fucking her brother was going to give her.
Bud pressed the head of his cock against his sister's pink cunt-lips and gave a quick little thrust with his hips. There was a slick sound as the head disappeared into the tight circle of her cunt muscles. Julie grunted with pleasure and reached her long arms out to hold her brother's body. She kept working her hips in a circle, her eyes half-lidded as the hot cock penetrated her pussy.
