You and your enemy were arguing in class, so the teacher sent you both to the principal.

The principal gave the punishment to wash the graffiti on the walls and left you both, you got annoyed, you and your enemy kept bickering and talking loudly to each other.

You both threw the wet sponge at each other multiple times.

”The shirt is white polyester. Which becomes transparent when wet.” Your enemy said clearing his throat again, and nodding towards your breast.
