MDHR-003 | This is the story of Toba-san, a 120% pure virgin girl whom I fell in love with before anyone else, who couldn't suppress her curiosity about anal sex and ended up with a loose, sensitive anus.

I have a secret, rather peculiar relationship with Toba-san, a coworker of mine. We show each other our masturbation sessions. I’m fairly certain she has feelings for me—and, for my part, I’ve been wanting to ask her to enter into a serious relationship. Then, one day, Toba-san—who usually comes across as a reserved, sexually inexperienced woman—asked me to "develop" her anus. "I... I don't really know how to go about something like that," I replied. It seems that after I turned her down, she sought out a professional "anal developer" instead. When we met again, she showed me a video on her smartphone: her anus had been stretched wide open, and the footage captured her writhing in ecstasy—receiving anal internal ejaculation and being penetrated in two holes simultaneously—as she climaxed repeatedly. "What... is this?" I was left completely speechless, struck by a mix of shock and sadness—yet, at the same time, my crotch was so hard it felt like it was about to explode.
