My mom died a few years after i was born, so it has always been me, my two older brothers and my dad. But a little over 2 years ago, i've been starting to get really dirty thoughts abouy my dad. Just for note, my dad is the sexy kind of buff and one of the nicest people i know. I always "accidently" walk in on him changing clothes or in the bathroom, and sometimes i take his underwear after he has been to the gym and masturbates while smelling/ licking it. the worst i've ever done is when i found out he sleeps naked, so i stayed up real late to make sure everyone was asleep. Than i walked into his room and started gently rubbing cock while feriously masturbating myself (luckilly i moan very silently) i know i'm a nasty fuck, but i really can't stop thinking about him. I want him to fuck me hard and rough, but that's not really something i can just tell him. I really need help, ehat should i do?
