How is this different than Mother/son roleplay? I find it's what I get requested most often. it has NOTHING to do with one's feelings towards one's biological family/family of origin: it is sexual psychodrama! When I am participating in Mommy/son play, I am not committing an act of incest, nor is the gentleman, because we're not related by blood, or by marriage. I also do Daddy/daughter play...but for older Daddies, mostly! I don't judge; I embrace diversity.
