One Man Thumb War

Sexual act involving masturbating a girl, then having hand fall into the vagina without much effort. Man then begins to make thumb war motions inside girl. Works best on a loose girl.

I was totally getting it on with Darcy, and I put my hand down there, but it was a total one man thumb war not even a minute in.
