A variation of “soaking”. An unmarried Mormon couple go to the top bunk on a set of bunk beds. The Mormon guy puts his penis in the Mormon girl, but holds still because if he thrusted that would be
having sex, which is a sin. A third person then gets on the bottom bunk and kicks the top bunk so the couple can
experience movement, but they will be
in the clear because it’s not them doing the movement.
