I took my clothes off and noticed both boys were ogling me in my swimsuit, so I quickly jumped into the water. We larked around in the water as you do...Then for a laugh as Thomas was stood on the steps leaing into the pool, I tugged at his shorts, not realising how loose the were, as his shorts came right down. I could see his willy, which was all shrivelled up. I giggled as I thought it was so funny. Thomas pulled his shorts up and got upset and ran into the house crying. I looked at Daniel,. She told me to stay there as she went into a cupboard and pulled out a mixture of dvds and a vibrator or two. I was happy watching her as she put the TV on and put on a dvd, telling me she loved watching porn as she fucked.Jane looked at me as she freed her tits, probably a good 34DD at least. She straddled me as she told me to suck on her tits. Her nipples were big and brown, which were great for sucking on. I started to nibble then bite lightly on her nipples as my right hand cupped her. "As she got the dress ready I took off my shoes, pants and shirt. She then approached me with the dress, "Here we go, let's just slip this over your head. Oh my, this isn't going to work at all. Your underwear is much too rough to slide this dress over, but I've got an idea." I saw her go to her dresser and open a couple of drawers and she returned with a few things. Oh my god, she had a pair of panties and a shiny nylon slip in her hands. I said no way was I going to wear those things too,. I was a little surprised to see that their pussies were shaven and I asked why. "When my sister and I masturbate each other we prefer not to work our fingers through a mass of hair to put several fingers into each others pussy" Joan answered. My cock had grown somewhat at the sight of the naked sisters and, as on previous occasions, both came to me and each held it as I now, for the first time, put several fingers into each cunt and we all masturbated each other. I was the first to cum but Joan.
