Yuki Nee-chan no Kannou Gokko.

A high school freshman named Shin Yuki discovers his childhood friend, Yukino Kurose, a third-year student, performing a reenactment of a sensual novel in an empty classroom. She is nude and using a mannequin for the performance. Yukino used to reenact stories with Yuki's help when they were younger, to better understand the characters' emotions. This time, she asks him to assist her again, as the mannequin is insufficient. After some thought, Yuki agrees to help, not wanting anyone else to see her in that state.
