This time, we're getting up close and personal with Ayase-san, a sauna mistress in her second year, and Morisawa-san, a sauna mistress in her fourth year, who make the already scorching sauna even hotter. A sauna mistress is someone who skillfully uses towels to deliver the steam that builds up inside the sauna to the customers. But this sauna is a little different. While drenched in sweat and being relentlessly fucked, she sends out heat waves while shaking her large breasts. Always fucking, always smiling! The humidity is sky-high thanks to her squirting! This sauna was a popular spot frequented by repeat customers thanks to its popular sauna mistresses.
