“Man, Sally’s such a slut.”
“Yeah, she let Tom and I give her a Newton’s Cradle last night.”

Newton's Cradle

2 guys, 1 chick in the middle. One guy puts his balls next to her left ear, and the other on the opposite ear. The two guys rock, paper, scissors on who goes first. The guy who goes first lets his balls hang then lets go, hitting the chicks ear. Then the energy is transferred due to elastic collision.

Bruh, me and my homeboy Tony fucked this chic. We did the Newton's cradle and she ended up with a concussions.
