Alaskan Cowbell
When you have a girl hanging, naked, head down via harness. You then have a male do a hand stand, naked, with his ankles locked with the girls ankles. Then the man does arm squats down and up (speed depends on the males strength) thrusting his penis in and out of the girls vagina while squatting.
