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. But why? Lately, I've been overcome by a strange feeling. "I want to destroy Ruka." Perhaps it's the influence of an adult video I recently watched. I don't know what's causing this feeling. Before I knew it, I was saying strange things. "Do you want to try some SM play?" Ruka was hesitant, but she went along with it. And so we became master and slave. At first, it was just a casual feeling. Just a trial run. I never thought it would end up like this. I never thought it would end up destroying Ruka. That she would become a masochistic pet, shaking her legs obscenely and begging to be trained.
