Placing your testicals on a persons face who is lying down and placing your hands on their needs behind you, then proceeding to deficate whilst dragging your testicals down their face and body with a rowingmotion
I was with a girl/guy last night and they let me go dragon boating on them
An act similar to motorboating, in which one uses one's penis instead of one's face. Similar to tit fuck, however the key difference being that the penis is wiggled in a side-to-side motion.
Bro, did you motorboat that Rachel chick yesterday?
Totally! But afterwards I was totally dragonboating her!
Seriously? Dude! High-five!
