I'm addicted to my roommate's boyfriend and his hairy body.

Why do i always end up the same when i see my roommate's boyfriend? he is somewhat sick but as soon as i see him and we are alone i cannot control my desire to have his hairy body only for me. the tickling of her hair in my hands drives me crazy when i jerk off his cock, or his hairy chest… i'm sorry but i can't control myself.
