Hey big boy you want a heated thumb warmer?

When you stick your thumb in a female's asshole while you're banging her doggy style. If she complains, you say it was to keep your thumb warm.
Bro, I was banging this chick doggy style behind a dumpster for hours and I gave her a thumb warmer. She was into it.
