At a hot spring inn, I ended up sharing a room with a cheeky junior female employee from the Yutori generation who had huge breasts... I had no choice but to sleep in a river-like position, but her sleeping posture was so bad that her big breasts slipped out! You could see her panties! Of course, there was no way I could resist the female employee whose yukata was open in front of me, so I started touching her timidly, but she woke up, and she was in a state of horniness! We were having sex without being noticed... The female employee woke up in the middle of our sex and joined in, in a state of horniness! It ended up being a threesome!
