I came to a hot spring inn together with Mom. While walking down the hallway, I met a beautiful woman who showed off her big tits and a slightly lewd pair of panties. When I was soaking in the hot spring, the same woman appeared and gently washed my body with her breasts. Later, we moved to the room where Mom was sleeping right beside us. In the meantime, the woman kept touching my body in a sexy manner, making it an intensely thrilling experience.
