SONE-270 After jokingly trying S&M play with a childhood friend… I woke up as a masochist and became an obedient, sensitive maso pet — Nanana Mifu

"Nana, today I'm going to tie your hands and make you my slave●." My childhood friend 'Nana' is cute and pure, like a little sister. Since we've always been close, seeing 'Nana's' panties never excited me... But lately, for some reason, I feel the urge to mess her up badly. I want to make 'Nana's' body all messed up and have her say things like "Please forgive me, master." I might be going crazy... Thinking this, I half-jokingly played SM with 'Nana,' but before I knew it, we started full-blown intense SM sex... [Pure girl becomes a D/M slave]
