Come on in! Succubus-san ~Hungry Mere Squeezes Out Your Semen Tonight~

Seitoku Gakuen is attracting attention as a model that focuses on sex education in response to the declining birthrate.
However, behind the scenes of sex education at Seitoku Gakuen, there is a rumor that a “forced semen extraction club” has been organized to squeeze the semen from male students.
In the “Forced Semen Squeezing Club,” sex-starved female students do as they please and squeeze the target’s semen until it dries up.
Takashi, who entered without knowing such rumors, was spending his days as usual.
One day, while Takashi was sorting out the handouts that her homeroom teacher had asked her to do in her classroom, a female student approached her from behind.
