In this dark adult school role-play, Yui’s uniformed adult student character is trapped inside a sweltering train after an emergency stop, blackout, and door lock failure leave no way out. Even the teacher meant to protect her loses control after seeing her wet herself. He kisses her trembling lips, grabs her, and assaults her, inciting the surrounding men to join in. She is gang-raped, forced to suck multiple cocks, and creampied again and again until her body is covered in semen and overwhelmed by twelve frantic orgasms, leaving her completely conquered by the abuse.
