We all know what motorboating is, right? Boobs…put your face between them…bbbbbbbbb!

So, I’ve invented the advanced motorboat. You get two girls to stand close (shoulder-to-shoulder) so that they form cleavage with their boobs closest to each other (the girl on the left’s right boob and the girl on the right’s left boob).

I think you see where I’m going with this.

Motorboat away in the newly formed dual-girl cleavage. You sir, are a master.

You’re welcome.
