In the 70s my girlfriend was a professional hooker and dominatrix and took me on as one of her live-in males slaves. She had friends that owned a Hollywood sex shop and was able to obtain her first dildo and harness. Behind our closed bedroom door, I found out what it’s like for a guy to get fucked in the ass by my dominant girlfriend. Whenever I bitched about not getting laid my girlfriend strapped on a dildo, took me to bed and give me a good butt fucking. She knew how to fuck me until I came, and then to my surprise, she would keep fucking me even longer, because the end of the dildo gave her much pleasure stimulating her clitoris.
