Newly appointed female teacher Rika-sensei engages in intimate interactions with her students during a sex education class. The charming Rika-sensei, with her tight and adorable appearance, begins measuring male students' bodies, quickly escalating into increasingly erotic situations. Suddenly asking, "I need to measure your penis, so could you please get an erection?" her bold request leaves the students flustered but compliant. As students crouch down for measurement, Rika-sensei carefully proceeds, ensuring clear visibility of their cocks. In between measurements, she collects leaked semen as samples—an unusual part of the curriculum. Encouraged by a student saying, "Don't be shy, show us! That's what education is about!" Rika-sensei grows even more enthusiastic, using a glass rod to measure her own slippery pussy opening. As students exclaim, "H-hey, the teacher's pussy is getting wet!" she becomes increasingly aroused. Her body thoroughly touched and examined by the students, Rika-sensei's sensitivity heightens. During practical intercourse training for gender selection, she actively grinds her hips in doggystyle, craving deeper penetration—an intensely erotic sight. Her moans of "N-no, no, no, nooo!" only intensify as mouths cover hers, amplifying her sensitivity, matching the rough play favored by the students, who flood her with hot, youthful creampie after creampie. Finally, as the students cheer, "Thank you, Rika-sensei!" she ends the session looking deeply satisfied.
