A three-some consisting of two girls and a guy. The guy lays on his back while one girls rides him and the other sits on his face. The two girls face each other holdings hands, creating a triangle or "Sail".
The same thing as Eiffel tower but for 2 girls, 1 guy.
ddannnggggg! Dina and Snooks really know how to go sailboating!!
The acting of rocking a mans member (aka sailboat) back and forth inside a womans vagina (aka cum-boat), this process is refered to as surfing her seas, after which the man finishes within her, this process is refered to as "unloading cargo"
*all aspects must be followed to be considered sailboating
Friend 1: "Dude, what'd you do last night?"
Friend 2: "Not much, just some sailboating."
Friend 1: "Idiot! Think she'll get pregnant?"
Friend 2: "I dont care, not my bitch."
