"Take your stupid pants off," she chided as he stood there, staring at her.

A tingle of excitement rippled through her body when he dropped his pants and shorts. Earlier in the evening, she'd only been able to see his prick, but now she was staring at a boy's balls for the first time in her young life. Her startled gaze focused on his hairy sac, which swung lewdly between his muscular legs. The sight of his long, hard prick thrusting up from the mass of curly pubic hair made the juices flow hotly from between her cuntlips.

Crawling into bed, Bob drew her soft, warm body up against him. He covered her moistly parted lips with his mouth as they rubbed their naked bodies against each other. He slowly moved his hand down over the smooth flesh of her back until he had her soft asscheeks gripped in his palm. As Bob pulled her naked body closer to him, Terri could feel his throbbing prick burning against her quivering belly.

Finally releasing her ass, Bob trailed his hand around her body until it was resting between her inner thighs. Trembling with lust, he let his fingers slowly wander up until they brushed against the hot, juicy opening of her virginal pussy.

"Mmmmmmmm!" Terri excitedly moaned when his finger gently moved up and down along the edges of her soft, wet cuntlips. Dipping his finger into her creaming fuck slit, he slowly moved his fingertip up toward her erect clit. "Oooooooh, Bob! That feels so neat, honey!"

Bob had fucked his share of girls, and he expertly massaged his sister's clit until she was squealing with joy. He began plunging his thick middle finger in and out of her juice drenched pussy, brushing against her clit with each thrust. The ecstasy was almost more than she could stand. With every thrust of his plunging finger, he was carrying the squealing girl to new heights of blissful excitement.

"Oh, Bob!" she squealed, wildly rotating her slippery cunt around his thrusting finger. "Go faster, honey! Don't stop! I'm gonna come! I'm almost there!"
