ZUKO-009 We had an orgy during a drinking party.

Let's meet in front of the station and have a drinking party. - Feeling good, we secretly have sex. - It started to feel good, and as I was shaking my hips in a daze, I could hear the moans coming from the other room. - They are surprised when they witness the sexual act of the girl they were drinking with until just a moment ago...but instead, their sexual desire accelerates and they get into an orgy.
