HMN-854 Futanari-style exposed bulge J-girl: The moment a penis appears, her overwhelming libido and oversized erection spill out, and with her shy, unknowing teasing, she distracts a beautiful schoolgirl in uniform who can’t even focus on studying for exams. Perverted teacher Misao Oguri drives her to the limit with a double pleasure trap of climax and internal release.

One day, Misao accidentally drinks a male classmate’s vitality supplement. Whether that was the cause or not, it triggers an incomprehensible chemical reaction, and she ends up growing a large penis. Unable to control her own erections, she starts touching it. The overwhelming pleasure she has never felt before leads to a huge climax. And then, to make matters worse, a perverted teacher finds out. Between classes and after school, the bulge under her skirt and the size pressing out from her underwear make it impossible to focus on exam study, leading to relentless, inappropriate guidance. Overcome by the unknown pleasure of having both sets of genitals, she smiles through repeated climaxes. More than 20 intense releases in total. A runaway, uncontrollable climax hell that drives a beautiful schoolgirl in uniform out of her mind.
