SFW Grink's Cleaning Service part 3! (Patreon)

This one is a bit of a longer one and the last of the costumers for a while.  There are gonna be around 2 or three chapters dedicated to 'dates' between Grink and previous costumers.  This way, you can still get a taste of the character while not still going along with the formula for service that this and the other chapters follow. :)
