I came to stay at a hot spring inn. When I entered the open-air bath that the inn boasts, I found that it was a mixed bath, and female guests were bathing one after another! I couldn't help but take a peek, and I was very excited to see that they all had beautiful, natural big breasts! When they noticed my cock that had been erected, they started to get horny, and they came to me in the bathroom and the guest room without caring about the people around them!
