buttpounder with cheese 

A well endowed gayer's stonker.
More than just a mouthful and requiring a two handed approach.
Cums with a 'Special sauce' or gentleman's relish and often found between two buns.

Keanu bent over ready to take a hammering from Steve's buttpounder.
Steve got ready to chow down on Keanu's buttpounder with cheese.
