They work at the sauna and capsule hotel "SHIGEKI". We interviewed Misono, a second-year thermal therapist, and Aizuki, a first-year thermal therapist, who both calmly go about their work. A thermal therapist is someone who uses a towel or fan to pour water onto sauna stones in the sauna, creating steam that customers are showered with, but the sauna here is a bit special. While being penetrated with total concentration and sweating, she shakes her big breasts to send out heat waves, and even attaches a vibrator to her sensitive nipples to shake them further! This sauna, which has a popular thermal therapist with a large number of repeat customers, uses tide aroma instead of aromatic water. Bathe in tide heat waves!!
