Performing oral sex by not putting the penis inside the mouth, but rather licking it's whole length from the side.

sierra

Destroyer of worlds. Extremely beautiful, smart, funny', but makes some dumbass decisions. Ain't gonna lie. She is super nice, and for some reason becomes friends mostly with fakest people in the world. A lot of guys like her, but most of them won't admit it. She may not have the best reputation, but she still thinks she does. She's everything a guy would want. She still choses the fucked up guys that would hurt her, instead of some good ones. She friendzones A LOT of guys, I mean.. a guy that she actually believes is her best friend who's a guy, has a crush on her, (probably).

Why is Sierra talking with Moses , that guy is cheater?
Sierra destroyed me in FIFA
