Two people, a guy and a girl, missed the last train and ended up in a mixed-bath hot spring experience. Shizuka-chan, with a model-like body and big breasts, and Takuya-kun, a normal-looking nice guy. We knew that male-female friendship wouldn't work, but as they bathed together, they got turned on. It wasn't just a little make-out or holding hands; it escalated to full-on sex. They had no mercy with creampie, and Shizuka-chan had no shame as she came over and over, leading to a long, intense sex session.
