pendulum effect 

When a man maintains a fast pace of thrusting while having sex with a woman in the Doggystle position so as the man`s balls are swinging forward and knocking against the woman's clitoris making her orgasm even faster.

Normally it takes Heather a long time to come but last night was much faster because she was induced by the pendulum effect.

sperm pendulum 

When a porn actress blows a guy and he cums. She then lets a big glob leak out of her mouth for the camera and instead of dripping off, it swings back and forth from her chin or from the guy's cock.

Man, did you see the sperm pendulum hanging off that girl's chin in that last scene?

Entering a man from behind while he is already balls deep in another man, then proceeding to thrust. Thus creating a testicular penetration pendulum.
