They lay together on the bare tile floor. Somewhere along the way the bath mat had become wadded up. Penny's skirt was bunched up around her waist and her blouse was open. Her tits were out, heaving up and down as she struggled for breath.

Billy's weight was heavy on her, but she wanted him to stay inside her. Even though his prick was limp it still felt good to the horny teenager.

Penny was the first to recover her breath. She hugged her brother to her breast. "Can we do it again?" she said.

He lifted his head, groaned and dropped his face down to her tits. "Jesus, Sis, a guy can't do it again right away. A guy's got to rest before his cock gets hard."

"Is there anything I can do to help?"

Billy raised his head and grinned. "Jesus, Sis, you're too much."

Dropping down, he nuzzled her tits with his lips. She felt his cock stir inside her and hugged him.

"Well, I guess I'm not a virgin any more," she trilled.

He sucked her nipple into his mouth. Me either, he thought. Jesus, we're neither of us cherries any more.

CHAPTER FOUR

The next few weeks passed slowly for Pam. She lived in a permanent state of horniness. Chuck bored her and her pussy ached for new adventures. But her mother kept admonishing her to be chaste even while she brought her own lovers to the house.

Then one day when Pam dropped in at her brother's house she found him home alone. Judy and the children were out for the day. This was her perfect opportunity to talk to Bob about her problems with their mother.

As they sat in the den and chatted, Bob made them both drinks. They spoke openly and honestly about Pam's troubles. Bob advised her to move out and get her own apartment. Pam promised she'd think about it.
