Professional AV sauna- Yuko Shiraki is in a tent-style outdoor sauna, climaxing like crazy! Sauna → cold bath → outdoor bathing followed by "plus sex" is a godly realm that even Yuko has never experienced! A dick is inserted into her parasympathetic-dominant body, and she is once again drenched in sweat and reaches a massive climax! She is very satisfied with the sex that is brought about by the squirting self-loyly, which gradually raises the temperature in the sauna! Instead of a meal, she takes the virginity of a virgin on her way back from the sauna, completing her indulgence!
