IENE-266 A man loses his virginity during a solo hot spring family trip! During my first mixed bath in 10 years, I desperately hid my foreskin penis, but my mother and sister's pranks turned into forbidden sex education! Sorry, Dad! ～

A family trip where my father couldn't come along. My mother and sister don't seem to think of me as a man, changing clothes casually in the same room… And then we went to an open-air bath and it was mixed bathing! But usually, I'm surrounded by women and feel like I don't belong, so maybe because it's a trip, everyone suddenly seems really familiar. What? That body contact is inappropriate, isn't it! I'll get an erection! Because I'm still a virgin!
