He meets a female boss Kuno Hinano on a business trip and gets drunk and gets fucked raw while he's in a lodging place.

I was drinking with a female boss (Kunino Hinano) from a business partner I met on a business trip, but when I missed the last train, I ended up having an after-party at the hotel where I was staying! She gets drunk and gets fucked hard by kissing and giving him a blowjob and having raw sex!
