They began tearing at their clothes. Pam was naked first and she tried throwing herself at her brother, but he held her back.

"Let me look at you, Sis," he said. "My God, you're lovely."

The young blonde trembled as his eyes swept over her. She felt no self-consciousness. She felt proud and happy that her brother, the one man in the world she adored, was drinking in her curves.

As for Bob, he was amazed at his luck. He'd had the hots for his kid sister for years, but their mother was overly protective of Pam and he never thought he had a chance to get in her pants. Now in a few minutes he was going to shove his aching prick into her almost-virginal cunt. Christ, when she comes around my dick I'll go through the ceiling, he thought.

They fell down onto the sofa and embraced. "Jesus, Sis, you feel as good as you taste."

"Thanks, Bob," she said hoarsely. Her hands were all over him. It seemed that after all the years of inhibiting her sexual needs she was finally letting go.

He still wore his shorts. Pam wasn't daring enough to take his cock out, but she stared at the bulge in his crotch and even stroked it briefly.

"Is it hard enough?" she said, with childlike candor.

She cradled his head when he buried his face against her pillowy tits. "Why not find out for yourself?" he said as he nibbled her tits.

"Oh, Bob," she giggled.

He guided her onto her back on the sofa. Her legs were spread to accommodate him and she arched her back to encourage him to resume sucking her tits.

Chills ran up and down her spine as he kissed and licked and sucked her tits. Her nipples were very hard and swollen. They ached with arousal, but even the slight pain was erotic.

Fuck me, Bobby, she thought. Please, fuck me.

She had never felt more aroused. When she was with Chuck she usually had to fantasize because in truth he left her cold. But Bob turned her on completely.
