Can I take off my shirt and work naked?

The janitor looks him up and down and then bursts out laughing.

-Do as you wish, but you really must be one of those compulsive exhibitionists if you find a torn t-shirt that leaves your butt exposed suffocating. Anyway, make yourself at home.

K-T grabs the bottom edge of the T-shirt and as he starts to lift it, slowly revealing first the knees, then the thighs. He explains.

-My nudity is always or almost always the result of various accidents, and that's precisely why I've learned to prevent them. For example, I realized that one of the nails on the grate is slightly out of place. I'm absolutely sure that if i had gone down with the t-shirt, it would have gotten caught on that and in the end, i would have torn it, making it unusable.

He says in one breath with the fabric lifted above the navel and the penis, no longer restrained, has resumed its erect position. Taking off his t-shirt completely under the scrutinizing gaze of the janitor, K-T carefully places it in a spot that seems to pose no threats to that fabric so precious to him. He returns to the grate and slips into the duct. Below, he finds a sense of security and protection. He manages to sweep up the dust and dirt, collect it with the dustpan while bending down through the grate, and there he is, with only his head and bare shoulders sticking out, putting it all into the first bag. After a while, even the dust on him, against the soles of his feet and on his body, no longer bothers him, and the only inconvenience for the movements he has to make is his erection. Now even the chapel has been revealed, and its vivid red is streaked with the thin white of a drop of sperm. K-T try to think of something else, something that won't worsen his condition, because as much as he struggles to admit it, he finds himself excited by situations where he is humiliated. In this case, a true first time, he undressed himself. It was his choice. He reflects on the fact that the principal has proven to be more fair than expected, even though he is under the threat of expulsion, which would mean failing and no more college, but a job somewhere probably as menial as the one he is doing now. Try to sweep away the bad thoughts like K-T do with dirt. Without realizing it, between trying to dispel the erection (with little success, also because it's difficult to reduce the trunk he has between his legs) and imagining a grim future, he collected almost everything into the bags. Finished filling it, he puts it outside and then reaches it by pushing himself with his dirty arms, and after a short crawl that reveals a butt as black as coal, he gets back on his feet. The janitor got up from the deck chair and after looking through the grate to compliment him, he brushed his penis.

"Oops, sorry," says the janitor, realizing the gesture.

K-T does nothing to cover or move. On the contrary, from that friendly gesture, a bit like men in a locker room, he became convinced that the janitor has no ulterior motives.

-Seeing as you're in such a state i'd say you can only do one thing.
