Most of the time I think about coworkers, previous coworkers, and friends! They are usually just fantasies...but they definitely work lol.
I'm a guy, but I have had two women have orgasms while giving them a massage. It wasn't an adult or erotic massage either, just regular.
I definitely remember...it was a cuckold situation. The woman pushed me on the bed and her husband watched. She was dying to blow me since I'm uncut and she had always wanted an uncut man (I wrote a 3-part story about it, most of the story is true).
