Natsuki Minami"First Teacher" full-length work!! Students in the photography club ask Minami sensei to be a model. Pushed by the students' enthusiasm, she models, but she is gradually made to pose in obscene ways and photographed with a vibrator and a dick in her mouth. A male teacher sees her and, under the pretext of educational instruction, he thrusts his dick into her at the store where she works at night, raping her while she cannot make a sound and leaks milky fluid. The next day, she falls into the trap of the principal and a male teacher and is forced to model in front of the students for a sex education class. She squirts a lot from the shame and pleasure, and the male teacher and student have a threesome while giving educational instruction.
