Skewered Ox

Sexual position in which two guys kneeling, facing each other, girl between them: one cock in mouth, and the other in the vag. The trick is, that the girl must be curled up in fetal position, and the two guys must hold her whole weight by the sheer force of their erected penis.

For added difficulty - set a campfire under the bitch, and turn her around slowly, as a skewered ox on a barbecue party.
