elk situation
A naked woman gets on her hands and knees. Naked guy #1 kneels in front of her, receiving fellatio. Naked guy #2 kneels behind her, performing anal intercourse. Meanwhile, guys #1 & #2 proceed to play cards ( blackjack, usually) on the womans back, being sure to throw down the cards vigorously at the end of each hand.
Yo, last night we were in an Elk Situation with this chick, and she kept complaining that we were hurting her back with the cards!!
