I start off as a mommy. I am changing my son wet diaper. But seems that he doesn`t like it at all, so  I try to convince him it is ok to wear a diaper by showing him this diaper on myself.  I show off how it fits me and act babyish. But suddenly this diaper starts to turn me on, my nipples get hard and I start to touch myself,  then I masturbate until I cum.
