NHDTC-199 - This time! A woman with smooth skin challenges a men's bath. At a hot spring inn, she is discovered as a woman by a large man and is penetrated again... It's really the worst!

Those women with smooth skin who challenged the male swimsuit challenge are now challenging the men's bath! They check into a hot spring inn disguised as men! With a 'secret weapon' learned from their failure at the pool, they head to the men's bath! A boyish girl tests her courage with only a towel wrapped around her waist! They are told not to dip the towel in the bath... it might be more dangerous than at the pool (sweat). A shameful mission that becomes more intense! In the end, they are discovered as women again!?
