The remix of the classic blumpkin. This take is when the girl is taking a shit (which is rumored to happen occasionally, believe it or not) and is giving a guy a blowjob at the same time.
Sally is very efficient with her time. She gives inverse blumpkins every morning to her boyfriend while planning out the rest of her day.
