Exorcist partners Takahiro and Yumiko corner a demon only to be sealed inside a school-like dimension. The sole exit requires finishing every sexual trial. Pure intentions shatter as Yumiko takes thick creampies from other men and Ren while the protagonist can only observe the inevitable corruption.
Trapped in the Inescapable Classroom Dimension
1. A final demon struggle locks the engaged couple inside an alternate space that looks exactly like a school.
2. No physical exit exists until every assigned challenge is completed no matter how degrading.
3. The closed environment turns every classroom desk and hallway into a stage for forced public fucking.
Childhood Friends Forced into Open Cuckolding
1. Takahiro and Yumiko kept their relationship pure until studies ended yet the dimension ignores all promises.
2. Challenges demand Yumiko spread her legs for strangers and family while her fiancé remains powerless.
3. Each completed trial leaves her dripping with foreign cum and one step closer to total NTR collapse.
Younger Brother Ren Joins the Corruption
1. Ren wanders into the same sealed space and quickly becomes another cock that must be satisfied.
2. Family ties offer zero protection as the rules force intimate acts between the engaged pair and the younger sibling.
3. Watching his own brother claim Yumiko intensifies the humiliation and seals the cuckold fate.
Perspective Switching and Pure NTR Progression
1. The story alternates between Takahiro’s helpless viewpoint and Yumiko’s increasingly willing body.
2. No combat exists so every advance comes only through completing the next explicit requirement.
3. Gallery access after clearing lets players rewatch every creampie and broken vow in full detail.
