[F] ask i crazy?

21F I made a throwaway account to post this, i had to get this off my mind. i’ve been with my boyfriend for a few years and this past year for some reason every time i have sex with him i can’t quit thinking about his dad. He lives with his parents and i spend a few nights a week there, his dad is a business professional and his work ethic is so sexy to me. a few years years ago my boyfriend found out his dad was having an affair for 7 years. his mom stayed with his dad due to her self esteem i guess? Or he will smile at me way differently than he does to anybody. When we make eye contact it just feels like there’s so much sexual tension. So tonight i convinced my boyfriend to have sex in his dads room and i’ve never been so wet and he noticed that i just pictured it was his dad fucking me, am i crazy for always thinking about his dad? It just turns me on sooo much. Side note, sometimes his dad will go out of the way for me and not others.
