I entered the house quietly wanting to surprise her. I hoped that she would put on this new outfit and we could have passionate midday sex!I heard noi...es from upstairs so I quietly went up to investigate. Peeking around the open door to our bedroom…I froze! There was Susan, naked, her eyes closed in passion, straddling the hips of a man lying on the bed, impaled on his cock! He was guiding her hips as she bounced up and down on his cock.“Oh! Yes!” Susan said as she continued to fuck unaware. I’ll cum with your cock in me. Just go slow and make me cum, Okay?” Sounded like a pretty good proposition, so I entered her slowly. She was so hot and wet. As the length of my cock slid into her hot pussy, I thought I would cum right then and there. As I started thrusting, she started moaning. I had to stop. I told her that if I didn’t stop, I would cum. She looked frustrated with my explanation. I started thrusting again. I raised her leg up and put her foot by my mouth. I love her feet and. Then mum & dad met a couple and got quite friendly. One night they said they were going into Minehead with the couple and would be back about 10. Action stations I thought and sure enough once they were out of the way, big sis said the magic words. I started to head for our bedroom but Pam said "no, we are going to use mum & dads bed and took my hand. Once inside we both striped naked and the first thing I thought was how her tits seemed to be growing from the last time I squeezed them. I ask. Lisa hadn't cooled things down either and had, in fact, taken off her blouse the last half hour and kept playing with Dan's cock, first through his pants and then opening them to reach inside. Fortunately the road had been completely deserted the last hour and Dan was familiar with the way.When they pulled up beside the large, dark house, Lisa quickly opened her door and got out. When Dan emerged and looked around, he couldn't see where she had gone, but saw she had dropped her blouse a couple.
