Boy was I wrong, and I was about to find out just how far off base my pristine perception of Colleen McGinny really was when it came to sexual antics.... scooted down some so her lovely creamy white breasts were at my head level. I extended my tongue out and very lightly flicked her left, non-pierced nipple, which again caused Colleen to moan out. I then rounded my tongue and sucked that hard little nubbin into my mouth and pressed her sensitive tissue against my upper teeth.“Oooh yeah! I like. Kate I dont understand. That bikini is not for me is it? I nervously said with a half hearted laugh, but I was dying inside and my cock wanted to break free of my pants. No silly, she said and got onto her knees. She ran her hands up my thighs and began to unzip my jeans. The bikini was just something to get you ready. She leaned against my legs so that her breasts rested on my parted thighs. My sister then reached in my pants and pulled out my cock. I jumped when I felt her hand go around. Andy came over and laid the other side of her and his hands started caressing her breasts as he did she moaned aloud again and bucked up squirting "Grab a towel she said cos im going to soak this bed tonight".I grabbed a towel and as i came back i saw Andy inserting 2 fingers up my wifes cunt,it was amazing the first time in 25 yrs of marriage i saw someone else penetrating my wifes cunt as he did so she looked at me as if for approval i just grinned from ear to ear , he started fingering her. He kept good on his promise. I received letters from him at least once a week. He would tell me what he was up to, - within reason anyway as we both knew our letters were read by the screws before we got them.- I missed him a lot.My father died a couple of years after I had been locked up, taken by a surprise heart attack. It really was a surprise. He had always been a fit, strong bloke, but the stress of his only son being locked up for 20 years took its toll on him. My mother then died within.
