Mike and Brad's cocks are both about half hard. But it's obvious that all four men are similarly equipped. David's cock is noticeably fatter than the ...thers. But they all seem to be about the same length.Nothing much changed once we were all naked. Not at first anyway. But soon the girls started flirting and teasing, both with the men and with each other. It wasn't long before people began to get together in twos and threes and start fooling around.I returned to Gregg's side when David and. Then when he saw two men coming our way, he grabbed me and started kissing me. He pulled my dress up exposing my ass to them. He saw it and came right towards us. They were talking to John about me. John asked them if they liked what they saw. A man grabbed my dress and pulled it up exposing my ass again. He put his hand in my dress and grabbed cock. He said "Is he a sissy?" John told him he was training me. John asked them if they fancied a handjob from me. They agreed. John followed me behind. I feared how to start. Slowly, I kept my hand in her neck and slowly moved downwards over her nighty and stopped at the breasts. I could not feel happy and once again starting from her neck, I slowly moved ,now this time inside her nighty an over her bra and kept my hands on her breasts. I could feel the stitches on her bra. Suddenly I moved my hands inside her bra and kept my fingers on her nipple.At that instant, my sister hold my hands in that position and she woke up and asked me what I was. His legs were waxed so my hands slid easily over his hot skin. I ran my hands up and down his thighs and then over the inside of his thighs. I didn't touch him there but his erect cock was only inches from my face. He was almost quivering as I touched him.We were starting to really get carried away. Maria was now sucking on one of his nipples as Sara sucked on his earlobe. I stood watching them doubled up with laughter. Meri came round next to me and winked at me. She pulled her bikini cup.
