A female teacher with huge buttocks rides on a man, greedily seeking his essence, ejaculating repeatedly and exploiting him sexually. (JUFE-519)

Ms. Mina possesses a bright and energetic personality and beauty, making her popular not only with her students but also with other teachers. She successfully developed a unique learning method: inducing adolescent male students to release their semen, thus focusing their attention on their studies. Moreover, the most effective method was to repeatedly ejaculate into their testicles until they were empty. To confirm the effectiveness, Ms. Mina used her students as experimental subjects, making them sway their large breasts and buttocks while she drained all their semen in one go!
