I did it with this girl, whose ex was a singer in some band.
We were fooling around, she puts on his cd. I'm thinking, whatever gets her in the mood...
We start having sex, she starts humming along to the cd first. Then she starts singing along to the lyrics.
I'm a bit uncomfortable at this point. After a while she yells, "Oh, Tom!". Which was that guy's name.
I got up and left.
