Newtons Cradle

A threesome consisting of at least two males, where one male is in the middle penetrating the third party and being penetrated by the other male, the middle male will thrust in and out to deliver pleasure to all parties like a Newton’s cradle.

Woman: “What’d you do last night?”
Man: “I was in the middle of a newtons cradle, talk about double trouble!!”
Woman: “man or woman?”

Man: “MEN.”
