MOPP-081 — I've Been Watching From Afar For Years As My Slutty, Devilish Girlfriend, Who Loves Masochistic Men, Plays With My Anus.

She was a classmate of mine, Sato Nonoka. By chance, we met again when she was transferred to my workplace. I have witnessed her "secret" several times. The first time I saw it was when we were in the same class. I still remember that intense incident as clearly as if it were yesterday.
