That was it for me, I wanted to fuck her so badly lol. I took my cock out again, crouched just a bit, and pushed it in, between her legs. She shifted ...lightly and my whole cock slid between her plump teen thighs. Her bare thighs were still wet, and a bit sticky, and the feel of naked cool girl-flesh around my cock was incredible.It gave me an idea too - her shorts were so thin and stretchy that I realised i could just pull them up over her buttocks. It took a couple of minutes to slowly push. I picked her up at her house one day at 10AM for a sex/BDSM filled day and her sister was there with her. She was going to come with us and join in. I had no problem with it and found out that she(Lynn) had been gang bang the night before by 20+ guys and was full of cum in her cunt and ass. And Jennifer wanted it. We decided to go to our church's basement for our fun. It was a dirt floor and we had used it in the past. We got there and went downstairs to the basement and stripped. Jennifers'. I walked through the house and looked out back. They were in the pool. I slid the glass door open and stepped out into the sunshine."Hi Daddy!" Tia squealed in excitement. "We were wondering when you would get home." Hello ladies," I replied with a smile.Tia came to the edge of the pool as Vicky tread water in the deep end by the diving board. "Come in the pool, Daddy," Tia invited. "Come and play with us."As I looked down I noticed she was not wearing a swim suit. I looked over by the chairs. Suddenly I realized that Diane was not in the bed with me and I had to go to the bathroom. I reluctantly let go of myself and rolled over to the side of the bed. I sat up, stretched and yawned as my cock flexed itself sticking straight up in the air. I looked around and saw my T-shirt on the floor near the corner and remembered that the rest of my clothes were downstairs. I got up and went to the bathroom. I could here the water running, but the bathroom door was closed. I really had to pee.
