Imagining my girl has a clitty

I was reading some posts from https://xhamster.com/users/kevinj631 which are amazing. i recently started to have a tough time getting hard with her. I learned I have to imagine she has a little cock swinging between her legs when we fuck doggy style which is every time now. she's a tranny in my mind, and luckily loves feeling tranced so I whisper in her ear to do as shes told. shes even walked outside naked and back up to my cock to get fucked doggie style. she's a good girl that i'm slowly corrupting and recently fucked her ass for the first time, which she hated that she loved it so much.
I'm happy to write some more? Thanks for reading my post xoxo
