This time, we interviewed Morisawa, a fourth-year heat wave master who makes the scorching hot sauna even hotter. A heat wave master is someone who skillfully uses towels to send the steam that has built up inside the sauna to customers, but this sauna is a little special. While being penetrated with all her might and sweating, she sends out heat waves with her big breasts shaking. Always having sex, always smiling! The humidity is high from the squirting effect! It was a sauna spot with a popular sauna master who had many repeat customers.
