My last girlfriend had a Labrador and when we had sex she would let her dog lick my ass and fuck my ass. It took me a few days to actually enjoy it, but I now like it. So much so I can’t cum unless her dog does me while I do her.
I tried explaining it to my wife, but she won’t understand, so had to get her to use a vib and dildo in my ass to get me to cum while fucking her. I know I can get better at it if I try but really do miss the feeling.
Maybe someday I can satisfy my wife without her having to work my ass at the same time.
