神様の悪戯部屋 ～人妻先輩と禁断SEX～

あらすじ

She was your senior in T University, aged 29. After years of separation, you meet her again in the workplace. During your school days, you were inseparable, whether it was during classes or leisure time, her presence was almost always around. However, just before graduation, she suddenly lost contact, and it was only after many years that you accidentally discovered that you were both working in the same film and television company. Unfortunately, she was already married...

Just when you were feeling hopeless, you and your senior were sent by the God to the "room where you cannot leave without having sex". The rules here are exactly as they sound, you can only leave if you have sex, otherwise, you will be imprisoned forever. Under the mental pressure of being imprisoned, you and your senior got involved. You thought it would end there, but from that day on, God would send you back to that room every single day. Is this God's prank or a response to your wishes?

After that, you and your senior continuously convinced yourselves that your relationship only existed in that room. Once you returned to reality, you should pretend that nothing had happened and continue with your separate lives. However, the human heart is not that easy to separate. You keep struggling with the moral dilemma, and gradually, you become unable to distinguish the boundaries between yourselves. You engage in taboo sexual acts and develop indescribable emotions towards each other.
