My boss is Matsu-san, who is like an older sister.He always smiles and treats me kindly.He was my idol.I was busy with work today, and I ended up working overtime with Matsu-san.I'm glad I finished work, but the time for the last train had passed.Then Mr. Matsu said he couldn't help it, so he asked me to buy some alcohol, and I went to the convenience store.As the drinking progressed, the conversation turned to my girlfriend.Actually, I broke up with my girlfriend a while ago, and my girlfriend Matsu-san asked me why she broke up with me.Embarrassed about her reasons, she hesitated to answer, but she was overwhelmed and she replied that it was because of my libido.I asked her many times, and she was exhausted by her girlfriend.While saying that, Mr. Matsu got drunk and fell asleep.When I came back from my seat to drink water, Mr. Matsu was sleeping with his skirt open.I kissed her out of curiosity.Excited by her good smell, I repeatedly caressed her over her clothes.But suddenly she came to her senses and hung her coat over her.The next day, I couldn't look straight at Mr. Matsu's face.A few days later, Matsu-san and I have to work overtime again...
