I started with some of the girls around my neighborhood who never did anything sexual. Right now I have 4 girls I am teaching 3 times a week. This is what I do each girl gets on there hands and knees naked I get behind them my cock is very hard it points up and is 8 and 1/2 inches long 4 inches around. I put my cock in the first one with and hand on my hips. I don't touch them they have to move back and forth and I don't move at all I stay very still. after about 5 minutes I do the same thing with the next girl. I don't ejaculate. After I do that to each girl 5 times. I stop keep my erection then I stand up and let then rub my cock taking turns I stand very still this goes on for about 20 minuets I don't ejaculate they also do the same thing sucking my cock I just stand there. I don't ejaculate the whole time I am teaching them this stuff. I reason I don't ejaculate is because these lessons or not about me having pleasure I do it just so they can learn. I have been teaching girls now for about a year. I also show them other thing to do with my cock. I get new girl every week. I would like to know what you all think of what I do and let me know your opinion.
