You Filthy, DIRTY Boy (Patreon)

Hello Patrons! I am trying to decide on the next animation, which hopefully I can voice myself. Here is some concept art. 

Raunch. Filth. Stink. This guy gets off on his friend's dirty underwear. He wears it and imagines his friend, wanting to be closer, adding his own dirtiness to the garments. Or maybe, it is his own underwear that he gets off on. Humping hands free into the stained undies and getting them filthier. What do you think should happen? This is still in concept, so I am curious what you think.

This is a bonus artwork for the month. Sadly there are no nsfw variations, but it's a test to see the interest in the content. Is it too dirty, or is it not raunchy enough?
