The story follows Takakawa, a perverted teacher with a huge cock, and his two favorite students, Mina and Kyoka, who are both blessed with big asses. Takakawa's daily routine consists mainly of secretly filming them. One day, the two girls realize they're being filmed and decide to turn the tables, using it as leverage to pleasure Takakawa's massive cock at their whim after school. From that day on, they engage in daily double-penetration creampie 3P with Takakawa's cock pounded into their juicy asses.
