Bury your face in those tatas while she spanks your monkey. That's a tugboat...no more, no less.

Tugboat 

Similar to Docking except an uncircumcised man docks with a woman with an oversized clitoris. I wouldn't think it would need to be said, but the man's penis needs to be larger than the woman's clitoris.

Jesus, Donna. Your clit must be 3in! What do you say we tugboat?

The tugboat is my favourite sex position. It’s like doing kegels with your ass.
