Ryoujoku Koukan Nikki [Shukuchokushitsu Hen] ~Higaisha no Watashi to Kagaisha no Sensei~

Ayase was kept after by her teacher.
That's the day she started keeping a diary...
His r*pes were many and ongoing.
When her voice gave out, all that was left was to endure...

Today she's here again in the "night duty room",
where she and her r*pist secretly rendezvous...
