taint

It's the small area between your balls and asshole. It's usually extremely hairy.

Hey Schrief, you lick a lot of taint.

fuel-tank

After having anal sex and ejaculating, the male keeps his penis inside the female's rectum until it gets flacid, then he proceeds to fill the ass with urine.

She said, "Fill me up!" so I fuel-tanked the bitch.

Since it's hard to pee when your dick's hard, you'll have to give it a moment to soften up before a good fuel-tanking session can take place.
