「柴崎はるちゃんに男性専用サウナに潜入してもらいます！バレなければ旅行券10万円と休暇をプレゼント！」そんな誘い文句とPの勢いに流され、渋々突入！脱衣所で生着替え！客の隣で洗体、サウナ体験！ボーイッシュなはるちゃんですが流石に体がエロ過ぎて即バレ！湯舟で、サウナで、脱衣所でハメられちゃいました！

“We’re sending Haru Shibasaki undercover into a men-only sauna! If she doesn’t get caught, she’ll win a 100,000-yen travel voucher and a vacation!” Swept up by that pitch and P’s enthusiasm, she reluctantly goes in! She changes right there in the changing room! She washes up next to a customer and experiences the sauna! Haru may have a boyish look, but her body is just too sexy—she was found out immediately! She got fucked in the bath, in the sauna, and in the changing room!
