A complex and strenuous sex position. Few people have done it and few know what it is. The girl lies flat on her back and puts her arms over her head and balances on her palms (and fingers only if possible) with heels on the ground so that her back is elevated from the ground. The guy does her missionary style but his heels and palms are on the ground as well. All this is taking place in the dirt.
Showtime: Dude i just pulled the dusty spider with my girlfriend last night!
Executive: Wow you could do it?! My girlfriend and I couldn't. Thats crazy! And mind boggling!
