IPX-438 Back home, the beautiful manager doesn't like to wear underwear

Because I was slow, I had to stay and work overtime to keep up with the schedule. Luckily my department head helped me complete the work earlier than expected. Then I invited her out for a drink to thank her. But I lost track of time and missed the last train. The department head invited me to stay the night at her house. Not wearing underwear at home is her habit, it was like she was inviting me. In a space with only two people like that, I can't control my desires anymore...
