In the sauna at Akasuri Spa, I relaxed while enjoying the soothing atmosphere... As I watched the woman giving me a massage with all her heart, my crotch became hot and swollen unintentionally! It must be an accidental erection! Since it happened anyway, I decided to show off my erection to the female masseuse! We entered a private room where she moaned and panted erotically, capturing the intimate moments of this mature woman on camera! A total of 16 participants!
