SNOS-403 Even during class, I’m secretly getting involved with a classmate who can’t hide her teenage hormones and keeps sneaking off for private moments at school every day. Sakika Shiragami

Shirakami-san! We’ll get caught!!

It’s fine. …Hurry up and come in?

I never imagined that days this out of the ordinary would come to me…

One day during class, I was absentmindedly watching the quiet, gentle, and cute Shirakami-san from the seat behind her.

I was thinking how cute her back looked, when she started acting strangely.

She was touching herself! Her hand was moving between her legs!!

And on top of her desk was a smartphone hidden under a textbook, with a large image of a man’s private parts filling the screen!

The serious Shirakami-san was touching herself during class…

Before I knew it, I was getting excited too and starting to use her as inspiration.

I got carried away and climaxed. My underwear got dirty.

When I looked up, Shirakami-san was looking at me. Our eyes met.

This is bad… Did she notice…?

The end-of-class bell rang, and Shirakami-san came over to me.

Come to an empty classroom on the third floor later?

My heart pounding at the unexpected turn of events, I went there…

And waiting for me was Shirakami-san, wearing sheer, revealing lingerie.

I forgot we were at school and got completely swept up in the moment.

That’s how the thrilling school life of Shirakami-san and me began.
