I could see he was watching me the entire time as he got dressed; he couldn't take his eyes off of me. This made me very horny.A few minutes later we ...ere both outside my house, ready to race. The park was close to my house, only a few minutes' walk, and was only a few streets away. I told him how to get there and said, "Ready? Go!"We both took off running. My boy toy doesn't run as often as I do, so I knew I had an advantage. But I also knew how motivated he was, which could make up for it.I. After about half an hour Katie sat up shyly and putting her bikini bra back on said she was going for a swim and did Dave want to come which he didn’t of course so off she went on her own.‘Beer?’ Offered Mark, why don’t you bring your towels over here and have a drink with me, so Dave grabbed them and joined Mark on his side of the hollow. They spent the next thirty minutes discussing life, Marks recent divorce and generally putting the world to rights until Katie returned, and Dave moved over. But he would have nothing of it. He urged me to get over my abashment, but there was precious little I could come up with. Thankfully he knew a better way. Leaving me in my own world he took recourse to a different route.

She pulled her shirt off and I was shocked because she wasn't wearing a bra and even more stunned when she slid her sweats off and wasn't wearing any panties underneath either! She basically stripped naked right in.
