I know it is wrong, but I have become obsessed with my stepdaughter's panties. I am constantly sneaking into her room, going through her panty drawer. Going through the laundry, sniffing her worn panties. Having elaborate fantasies of dry humping her, even f****** her, while she still has her panties on.
She is young of course, and has a really big, sexy ass. I know she is sexually active, and thoughts about her letting older men in her panties p***** me off but also makes me so h****.
I am masturbating at least twice a day over her. Of course, my wife doesn't know, since my increased horniness means that I am f****** my wife almost every night (and I have always had a thing for my wife's panties as well).
