Dean found his new favourite position; he really liked straddling my chest with my tits cradling his balls and his dick in my mouth while Ben pounded ...y pussy behind him.I think it was because I really really loved slavering over his cock as my orgasm built up. "I guess you have realised that with what I have done to you while Rocky was doing me" she said to me.A couple of weeks later Dean and I went to a party without Ben and I had a fair bit to drink.Dean and I ended up in a bedroom, I was. Jessica had clearly let Dan frig her raw last night!Deceitful little Jessica! I thought; they were just bad as each other!Closing my eyes, I savour the power I’m getting from their misbehaviour. My climax comes quick and clean with an image of the pair frantically fucking together.I lie back ... fully spent and contemplating why I was so turned on by my daughter’s affair with Dan.That evening I entered her bedroom as she dried off from her shower; just before she’d pulled on her. I could watch them from my second floor office at our house, and found her very sexy.My daughter was short, about 5' tall, petite, had small, "barely budding" breasts, and had been sexually active from an early age. Marie was much different. She was about 5'9", a few pounds over weight, "voluptuous" is the word I would use about her, and had full, heavy breasts . Janine had very light colored fuzz on her pussy, Marie had a thick patch of dark hair on hers.One night Paul and I went to the area. The fantasy would always stop there. Mostly because that would be enough to make him come, the hormones racing at the speed of light through his teenage body. But also because any additional mental picture would break the magic. Like this, the fantasy was complete. Less is sometimes more. His highschool years weren't the best of times when it came to sex, in spite of being quite popular. There were some fleeting encouters, kissing and feeling and fingering and a few blowjobs, but nothing more..
