Thapping Sound 

The sound, in the form of a rapid staccato, made by the slapping of a guy’s ball bag against the girl’s ass during sexual intercourse. The sound can also be made by the slapping of thighs. The thapping sound is usually accompanied by other fuck noises like moaning, groaning and heavy breathing.

I heard the thapping sound coming from their bedroom and I knew my parents were having sex again.

They let us out of work because of the approaching storm. Instead of going to the bar with the guys I decided to go home early and be with my wife. When I got to the top of the stairs I heard the thapping sound coming from our bedroom.

When I fuck Gina she gets really turned on when as soon as she hears the thapping sound and then she goes all out until she comes.

thrapping 

Slang; from lesbians in the military who have competitions to see who can last longest, the word comes from the sound made by several ladies masturbating at the same time.

The sound of the cadets thrapping in their bunks could be heard across the base.
