Mark sat down first, Alex sat in between his legs. Meggie sat across from them and spread her legs wide and wrapped them around her mothers. Her slick... skin looked gorgeous in the water, Mark thought. Her little nipples were soft and puffy now, they floated just above the water. Mark reached around and took Alexs breasts in his hand. Alex took a hand towel and helped clean the cum off her and her daughters face. When she was done she kissed her on the forehead. The three of them sat in silence,. We'd walk hand in hand, even kiss from time to time. Weacted every bit the dating couple. In places we visited regularly peopletook it for granted that we were a couple. My mental fog was lifting andI screwed up the courage once to ask about the incident back home. Andykissed me and told me things were going fine, "just as planned," and Iwasn't to worry. I didn't. I was safe and went on to enjoy myself.What I noticed most during that time was that I now filled out my brasand panties. My chest. Eventually we went to bed. He went to his room and i went to the empty guest room. It was still kinda early so i wasn't that tired, but the booze always makes me horny. So i started playing with myself a bit until i was stiff as a rock. I slowly rub my cock, closing my eyes and letting my imagination wander. All of a sudden i hear the door creak open. I quickly stuff my dick back in my pants and pretend to be asleep. Then i realized it was Derick's sister who had come in, she must have been at. I slowly eased more in pushing my dick deeper and deeper inside. Half way his ass started to resist as the thickest part of my cock tried to enter him. He let out a wince and pulled away from me. I eased back letting my cock slide out till just the cock head was buried inside, then I thrust in again till the thick part of my shaft. I repeated this motion several more times, each time his ass became more accommodating, until I could push past the thick middle. Soon my cock was buried deep inside.
