Get the Ass Motorboatingmug. Placing your mouth in between the butt cheeks and viciously and aggressively shaking your head back and forth while making the sounds of an out board motor (comparable to motorboating tits).

Get the anal motorboatingmug. A practice of shaking your mouth back and forth over the lucky birthday girl's (or boy's) breasts, an equivalent amount of times to their age.
Darn, it took forever to finish Barb' birthday motorboating because she is now 88 years old. My lips are numb.
