Ain't nothing like a motorbooty after a rough night working the streets for my daddy and his bbw. I just wiped!
Hoe, after you finish making that dolla for making those pigs squalla, get your fine ass over here and let me give you a nice motorbooty. Don't make big daddy pop off! My face + your plump ass = dynomite!
