The year is 20XX. This is a story set in a slightly bizarre world where bishoujo games—commonly known as “eroge”— are registered as cultural heritage. The “Bishoujo Game Academy” is a special educational agency established with the goal of preserving and passing on bishoujo game culture. As a teacher at this school, you work day and night with the female students on creative projects. The Bishoujo Game Academy’s most distinctive feature is, without a doubt, the “After-School Dick Rental” program! By submitting an application, students can receive hands-on training using real male genitalia. As the school’s only male teacher, you’ve been lending your penis to the female students as a “teaching aid” every day after school to build closer relationships with them—but then— One day, you discover the existence of “troublesome high school girls” who are causing trouble for your cute students. It’s a teacher’s duty to provide disciplinary guidance to sassy and rebellious students. To punish these troublesome high school girls with your cock, you use your authority as a teacher to summon them to the “Cock Rental” room…!
