rug fuck
The guy makes sexual entry into the vagina. Then the couple gets rolled tightly into a rug. Tight enough where you are completely constricted. The girl must use the pussy muscles exclusively to get the guy to come. The only part of the guy sticking out of the rug is his head and he bobs it around wildly while coming.
In the Orient it costs $25 for a rug fuck with an oriental whore.
