Suzanne is just six months old. Tanya's tits aren't just enormous, they're absolutely gigantic! Having gallons of milk certainly helps. But she's four...een now, and her titties have been growing more or less steadily since she was nine, so she's well used to having them by now.That's one reason I don't always think of Tanya as a younger sister, more as a big little sister. She's not as tall as me: I'm around five feet four, she's five one, but her build is more... well, robust. It needs to be,. It was also laundry day and I was totally out of boy-shorts. So I had decided to go to work with no panties on. Unfortunately the women were required to wear skirts. Well I would just have to make sure I wasn't flashing everyone. I was in Cory's office putting away a few books back on the shelf when I dropped one. I bent over not thinking about me being in my skirt and picked it up flashing towards the closed door. Well I thought it was closed. "Sara!" Cory yelled. I dropped the book that I had. Rachel and Jo had heard the girl's screams and had come out of their changing rooms. Rachel didn't have a bra on and has great, big tits, hot legs and a nice taste in bikinis.Jo followed Rachel. Jo has large firm tits, nice bum, chubby legs and looks great in a bikini. Tina turned to Jo and Rachel and said "I found these two having sex, I thought we could join in."Tina bent down and pulled off Jo's bikini then unclasped her bra. At the same time, I had pulled Rachel's bikini off and started to. Has N’s cock got longer? How much longer than mine now? Will he tell me about putting his cock up a friends arse, did it hurt and did they use a lube. Was N also arse fucked? It didn’t appeal to me. I bet M’s cock has thickened up and even if he is 4 years younger than me is his cock now longer than mine. The last time we mutually wanked we were both about the same length and thickness, with me being 14. I had another friend in our rural village “R” the doctor’s son. We were not wanking mates.
