Sometimes, just jacking off isn't enough for me. I need something nasty. Even though I would never ever do anything to her in real life, or even try to, sometimes I take my kid sisters panties out of the laundry. I finger them and look at the stains in them. Sometimes I wrap the crotch over the top of my cock and masturbate slowly and gently until I cum in them. Other times I like to smell them and lick them. I imagine Claire on her back in her bed rubbing off into them.
I know it's bad, but sometimes that's what I do.
As I say, I would never try to do anything with her. It isn't like that.
