What Was Intended To Be SM Play With A Serious Childhood Friend For Fun... But She Awakens To A Serious Dominatrix And Becomes A Sensitive Masochistic Pet At Her Beck And Call - Masuzu Mita

My one-year-older childhood friend, Marin-nee, is a top student, so I often go to her house to have her teach me. I recently told her I've gotten interested in SM play, and she asked, 'Want to try it...?' Yes! First, we play at tying each other up with cotton rope. Once I'm fixed in a humiliating position, there's already a stain on my panties... When she teases me with a brush, more and more of that lewd liquid spills out. I'm getting excited too, so I couldn't help but shove my dick in her mouth! Is this what they call irrumatio? She looks like she's in so much pain! It's unbearable~! Somehow, my sister doesn't seem entirely unwilling either. Is this what they call a masochist awakening? Maybe I have a talent for this. ...I decided to train her as my masochistic pet.
