Chocolate Motorboat

A cousin of both the motorboat and the cleveland steamer, this difficult maneuver can only be done by a true fecaphile. After releasing one's bowels onto a woman's chest the classic motorboat is performed to the delight of all involved.

After a violent shart onto Gertrudes chest Hector quickly spins around and they relish in a lovely chocolate motorboat.

Puerto Rican motorboat 

(N) Variation of traditional motorboat (loose-lipped shaking of one's face between breasts while making motorboat sound), whereby one motorboats a woman's ass(preferably a Puerto Rican stripper's ass).

I woke up this morning and totally remembered Puerto Rican motorboating 2 strippers at Frenchy's last night.
