Is it normal to use girlfriend's sister's pants?
From a young age I've been very sexual, ever since I found a Porn tape when I was 6 years old. Even before this I always found myself playing with my Penis, using anything I could find. I didn't masturbate as I didn't know how at that age, but when I reached 13 years old I finally did it, I finished and orgasmed; this led to an addiction of masturbation. 3-6 times a day. It wasn't until I reached the age of 18 that I finally lost it to a girl, then my cravings became more intense.
Cut a long story short; I'm 25 this year and I've slept with 10 woman so far, which isn't a lot really compared to my mates etc.
So I'm with a lovely girl right now, in a relationship; she has a sister who I am not attracted to relationship wise, but the fantasy of having sex with her really turns me on. Now I wouldn't actually do it... Unless she came onto me, which she wouldn't.
But a few times now I've found myself going into the bathroom at my GF's house, and taking a pair of her Sister's Dirty pants from the wash pile and sniffing them/ licking them and masturbating with them... I love the smell, the taste, but after I cum, I regret it, everytime. It is only when I am horny that I do strange and dirty things. In the past I've done a lot of weird things on this level, and I've watched some pretty strange and sick porn in the past. I'm always horny and I can't stop it, it's like an instinct, a craving.
Her sister is twenty-something, so legal and all, just to clarify.
Is this panty thing normal? Am I normal?
