Newly appointed teacher Yuu, constantly aware of her inexperience, is looked down upon and exposed to the lustful gazes of her students. Her vulnerable state draws out the raw, youthful semen of the boys, who cum inside her 20 times in a row, while fellow teachers smear her face with sperm and spank her relentlessly. Gradually transforming into a complete sex slave, she begins to beg for more, her body writhing in ecstasy as her pussy squirts repeatedly with lewd sounds. Finally, she's forced to drink the accumulated cum from their cocks, pushed further into a new realm of depravity.
