SONE-951 | I played around with my childhood friend and tried some SM play... She woke up to her masochistic side and became a submissive, lustful, erotic masochist pet. Ruka Itoi

Ruka and I have been childhood friends. We may be practically family now. And yet, I wonder why. Lately, I've been overcome by a strange feeling. <br><br>"I want to destroy Ruka." <br><br>I wonder if it's the influence of an adult video I watched recently. I don't know what's causing this feeling. The next thing I knew, I was saying strange things. <br><br>"Do you want to try some pretend S&M play?" <br><br>Ruka was hesitant, but went along with it. And so we became master and slave. <br><br>At first, it was just a casual thing. Just a trial. I never thought it would turn out like this. <br><br>I never thought I would destroy Ruka. <br>I never thought she would become a masochistic pet, shaking her legs obscenely and begging to be trained.
