I was hard and Diane got up and the chair and her tits hung over the chair and she spread her ass cheeks and said "fuck me in the ass you Peeping Buck..." I smiled and spat in my hand and gestured her sister to start licking Diane ass and to get it wet. Darla reached over and guided my dick into her sister ass and it was tight as my cock head just past her anus and a loud smacking sound was heard. I started to get into a good rhythm and her sister went around the front of the chair and they were. Mum gave me a little smile as she left the study and mouthed I love you be brave darling. Miss Wray told us she was sorry it had come to this but being thrashed was the minimum we deserved. She told us we would receive three strokes on each hand with the senior cane and she added we deserved the severest punishment possible.She ordered me to stand up first and stand in front of her with my arm out straight and my palm face up. I looked at my delicate hand about to be caned and thought this time. I only met her an hour ago. But that means my stupid brother doesn't know what he's missing. Well, at least one boy in the family was going to take full advantage of what this girl was offering. I began fucking her as hard as I could, not trying to pretend I was Sal or me. Not trying to pretend anything. This was real, the best fuck since they invented bisexual species! I was wrong, of course. No man could take full advantage of what Mona has to offer in one session. Sal's been fucking. Ken's lesson was always right before mine, so I could hear him playing when I walked in. He was really good. Much better than me actually, but that didn't bother me. Lots of people were better than me at playing the guitar. Ken and I had talked a few times about getting together to play and see if we couldn't learn something from playing with another player.I knew from my brief conversations with him that he didn't have a girlfriend and I though he might be the kind of guy my sister would like..
