What she saw made her bite her bottom lip hard and hold her breath.

Julie's brother was a college boy who'd played high school football and was doing pretty well on his college team. He was big and broad-shouldered and his blond hair hung long over his ears. He was on his back, his big chest heaving. What shocked Robyn most was that he was stark naked and so was his sister Julie. She was kneeling between his parted legs, both hands holding his big cock, her small red mouth sucked tightly around the swollen tip. Julie was a blonde, like her brother and for Robyn to see her lank hair hanging over the light curls around Bud's cock made Robyn feel strange.

For a second, she didn't believe what she was seeing. Julie had always been such a quiet, shy girl. And here she was, sucking her older brother's wick! When Robyn realized this really was happening, she thought of running, of getting out of that house as quickly as she possibly could. She didn't move, though. She was fascinated by the way Julie's small pink tongue teased the head of Bud's cock. It made soft, wet sounds as it curled around the throbbing prick-tip. Julie's lips opened and her head bobbed down.

"Yeah, Julie!" Bud gasped.

Julie let his cock-shaft slide deep into her mouth, then pulled her lips back up his length and finally took her lips away.

"You sure are hard, Bud. You're gonna tell me before you come, aren't you?"

"Can't you swallow it this time?" Bud asked.

"I don't know," Julie whined, making a face, her short nose wrinkled up.

"It doesn't taste that bad, does it?"

"It's weird. I'm just not used to it yet."

Buddy pushed himself up on his elbows. "How in the hell are you ever going to get used to it if you don't start swallowing some?"

Julie shrugged. "I guess you're right. I just feel a little funny about it. That stuff won't make you sick, will it?"
