Summary

Tadaaki is having a conversation with his wife Shouko, the school's infirmary doctor on the other side of the curtain. Meanwhile, Chika, Shouko's sister, is on her knees, servicing Tadaaki with her mouth and breasts. "No, no. My wife is on the other side of the curtain. I have to stop her before my wife notices...!" In such a situation, can Tadaaki refuse Chika's sexual advances? [Edited from DLsite]
