Ass play for man in relationship

I dont know what I thought the first time my DH asked me to play with his ass. I did it. It was something new and different for us but i just was unsure. Being the one that takes on a much less dominent role in the bedroom i struggled with the role reversal in terms of me having "more controle" than i was used to... However when I started really paying attention to how he was feeling and hearing his reactions to what i was doing, it got me more and more excited and turned on every time. I would just talk to her about it. Just because she isnt a fan of the recieving end of anal doesnt mean she wouldnt enjoy being on the giving end!
