When a girl is on her stomach, tying her both arms and legs together behind her into one large knot. Then hanging her from the ceiling. Preferably done so a bed is underneath (in case the roof caves in)
Then, swinging her back and forth so that as she swings forward, her mouth goes onto one guys penis. The guy thrusts with his dick and "passes her to the other guy and as she swings back the other guy is there and he puts his penis into her vagina or into her ass.
"Let's give her the swinging chandelier"
"Alright, make sure this time you pass her to me, though"
