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.
