START-210 Nagisa Ren-chan (23) visits Nasu Shiobara Onsen. Would you like to try going into the men's bath with just a towel on? HARD

A former celebrity takes on SOD's famous project, "Would you like to try bathing in the men's bath with just a towel on?" It's her first time bathing in the men's bath, and she's so embarrassed about her slender body that she turns bright red! The dicks of the average male customers who don't know anything about it are rock hard! The serious Koi-chan bravely endures this hell of shame! "It's nice to have this kind of thrill every once in a while! Lol."
