START-337 After closing time, I missed the last train because I was doing inventory, so I decided to stay over at my part-time job's house. I was turned on by her cute refusal to wear makeup

Hoshino works part-time at the same sports shop. One day after closing time, while the two of us were taking inventory, we accidentally missed the last train and ended up staying at Hoshino's house. Hoshino stubbornly refused to go without makeup, which fired me up. "I've always liked you, senpai." I thought it was just a little prank, but instead I ended up being drained until the morning.
