Playing SM games with her serious childhood friend, she unexpectedly awakens her serious masochistic fetish, turning into an obedient and sensitive masochistic pet—Mita Marin SONE-925

My childhood friend, Marin, who's a year older than me, is a top student, and I often go to her house to study. Recently, I told her I'd developed an interest in SM games, and she asked if I wanted to try it…? Great! First, we played a bondage game with cotton rope. After securing her, she had already soiled her panties… I used a pen to tickle her, and her lewd fluids overflowed. I got excited too, and couldn't resist wanting to shove my penis into her mouth! Is this oral sex? It looks painful! This is amazing! It seems my sister doesn't dislike it either. Is this a masochistic awakening? Perhaps I have a talent for it… I've decided to train her as a masochistic pet.
