She was a year younger, but she'd skipped one grade and they were now both in the tenth grade. She'd met new friends, girls a little older and they were always talking about their sexual experiences. She couldn't very well do much talking even if she wasn't ashamed of her incestuous relationship with Rod. Besides, she wanted to try all the sexual pleasure with a few of the fellows at school.

It would be wonderful if it were possible to be included in the swapping parties, but she'd settle for one or two or maybe even three of the boys she'd met. She would like Rod to agree to them trying to form a swap club at school. She was sure that a couple of her girl friends would go for the idea, as they liked Rod's body, and she was positive that many of the guys wanted to fuck her – along with performing other exciting erotic acts.

Would Rod be jealous if he saw her being fucked? Would he be jealous if he even knew that she'd let another fellow touch her? And there was the possibility that she might be jealous if she saw him putting the blocks to some other girl. Would it bother her to see him going down on Peggy or Julie? They put out, she knew that, and she had a hunch that they also had something going between themselves, so to speak.

Already naked, Rod waited and watched as his sister finished undressing and started putting on the dark nylons that he liked her to wear. The almost black material concealing most of her legs made the soft white of her upper thighs seem even more naked and caused his already erect prick to begin twitching.

Rod couldn't believe how lucky he was. While most of the guys in school were still jerking off and dreaming about getting their first piece of ass he'd already been fucking his beautiful sister for almost a year.

He couldn't predict her moods. Sometimes she just wanted to cuddle and kiss and only reluctantly allowed him a quick fuck. Sometimes he even had to settle for a quick suck and a hand-job. Other times, for no reason that he could deduce, she was so hot and eager that she wore him out.
