MUGON-065 I accidentally saw a girl secretly lustful at school

In an empty classroom, I saw a girl secretly groping her body. Unintentionally surprised and unable to move. I can’t hold my breath, but I can’t control my excitement. When I was engrossed in looking at her, my eyes suddenly met. She comes back to me with a hah. A stiff expression, a disheveled uniform, an unstoppable sigh, and a faintly trembling body. A long silence and an awkward atmosphere. I couldn’t help but see her looking down and not moving.
