Shoto going to one of those sketchy af massage parlors, since his back has been killing him lately, and pays for 1 session. He's then led to a dark lit room, was instructed to take off all of his clothes, then was given a tiny ass thin towel to cover himself.

He sits awkwardly on the massage bed and waits for his masseuse.

After a few minutes, a blond man walks in, a scowl on his face. "Lie face down half and half." The mans rough voice tells him while he looks for the massage oils he needs for this session.

Not wanting to deepen the scowl on the masseuse's face, Shoto immediately follows, almost forgetting to cover his rear with the small towel. He lies down and slots his face into the face hole, waiting silently.

The masseuse, Katsuki, takes out a few bottles of oil, sets it to the side and turns to face his customer, whistling when he sees that the tiny towel their establishment provides barely covers the other's ass.

Lets be real here, the establishment that Katsuki works at? Its practically a brothel, they offer sex in disguise as "massages", and hes 1000% sure, that this half and half infront of him is completely unaware of the true nature of their services.

Poor dude probably hes gonna get his back ache fixed.

Heh, after Katsuki's done with him, his back's gonna be broken (figuratively, hes here to make customers feel good, not make them sue him)
