A threesome where the girl is suspended from the ceiling by wrists and ankles. then one man swings her and another guy stands in front of her and lands his dick in her mouth. The switch on and off swinging, and doing.
dude, we gave that girl a mean swing set last night.
A sexual position, similar to the Bonesaw, in which two women and one man is involved. The man, wearing a strap-on on his ass, stands between two tables with women lying on them, face up. With the women's legs on the man's shoulders, he proceeds to penetrate forwards, and backwards, therefore boning both women simultaneously.
Dude! I ran the swingset on those two hoes last night!!
