King Dominius' Great Baths　Fullsize (Patreon)

The body of Dominius, a half-giant, cannot be washed by one person, so he must be washed by a large number of men.

Although you can't see them, there are several on his backside as well, and the one in charge of his buttocks has half of his body under his buttocks to wash his anus (lol).

The fact that they are all skinheads is a hobby of Dominius.
