When fucking a girl that is so fat, you cant kiss her and bang her at the same time. Therefore you act as a seasaw, creating a back and fourth motion between kissing and fucking.

Chinese Seasaw is the newest and coolest sexual game. It's when one guy is in front of the girl with his "" down her throat and the guy's friend is behind the girl with his "" inside her backside throat. The purpose of the game is to jam the penis into the respective opening thereby causing the other side's penis to fall off the ride. The great thing is that you can always get back on. The guy that finishes first loses the game. Chick always wins.
Dude..let's London Bridge it and Chinese Seasaw this chick!
