I'm a store manager and I have a wife. There is a cute part-time college student named ``Masuzu-san'' working at the store. She always supports me with all her might. One day, she worked late and couldn't make it in time for the last train...I also missed the last train...We had no choice but to head to a nearby hotel together. We arrived at the hotel, but unexpectedly there was only one room available...we ended up staying in a shared room. Afterwards, my girlfriend unexpectedly said, ``I love you, manager.'' He looked at me with his dark eyes... and kissed me... My rationality was blown away, I forgot about my wife, had sex with her repeatedly, and then we made love to her.
