furnace filter

While performing sexual relations in the ever popular doggy-style position, said male retreives his dirty underwear and at the perfect interval, stuffs them unexecpectedly in her mouth as she moans. Timing is crucial in this act. A quick getaway is sometimes needed. It is required by man-law to tell all friends when this has been properly executed. Thanks JP

"Cody told me he pulled off a furnace filter last night after bar time with that milf from next door. Awesome"

"You're my personal human furnace."
