Rai, 30 Years Old, Swimming Teacher

Rai struts down the corridor towards the swimming pool.

She's just about to enter the ladies' changing rooms, when she notices one of the weirder male students loitering by the corner. She pauses for a moment, and hears him muttering to himself.

"6699. 6699."

A thought crosses her mind. A suspicion. Nothing certain, but... Hmm.

Stepping into the the room with the female students, she casually walks around the permiter of the room, pretending to just be slowly unzipping and removing her jacket. She's already wearing her swimsuit underneath.

She takes careful note of each girl, and the locker she appears to be using, or just finished using.

That leaves... an extra locked locker. With a combination lock.

Surely not.

Casually, she steps towards the far side of the room, and goes to her own private locker. Without saying a word, she unlocks it, and removes the self-defence item she keeps inside.

An item reserved for any perverts or molesters that try it on with her when they think she's likely to be at her most ****.

A couple of students notice her holding it, and turn to her, with uncertain expressions.

"Um, Miss Rai, what are you doing with that?" One of her students asks.

"6. 6. 9. 9." Rai speaks the numbers out loud as she turns the combination lock, and clicks it open.

The door of the locker creaks open, revealing the young man inside. The pervert isn't touching himself, but he has a massive tent in his pants. Disgusting.

Angry gasps echo throughout the changing room. One girl shrieks.

"Itachi!" The girl from the broadcasting society says, sounding hurt.

"You know him?" Rai demands, her tone icy.

"We're both in class 1-B." She clarifies.

The cold, calm anger that she's felt so far flares up into a hot rage. This motherfucker was spying on a girl in his own class. What utter disrespect. How was she supposed to ever feel safe in that room with him again?

A little voice appears in her head - the headmistress, giving her most recent instruction. You are all to be much more lenient with the boys.

What ridiculous guidance.

Fine. She thinks to herself, as she raises her bat, covered in hard metal nail heads. I'll stay away from his face, and his balls. This time.
