Reverse Mongolian Butterfly

A Reverse Mongolian Butterfly is an incredibly complex sex position, which multiple steps are needed to preform said position.

Step 1: You must jelq your way to 12 inches first, 10 being the least, or whatever tool you use to make it bigger
Step 2: Your partner and you will go on each others backs (hence the "reverse part")
Step 3: The one facing the ceiling (top) will put his legs into a C position and a T arm structure, as the bottom (the one facing the ground) will do the same except the bottoms arm structure will be like a 3.
Step 4: You both will consume healthy amounts (but alot) of sulfur hexafluoride, so your voice is at a deep tone
Step 5: Sex

Woman: Ehh, maybe, but not anything boring like doggystyle

Man: Perchance, a RMB?

Woman: A Reverse Mongolian Butterfly? YES!
