Steamy Love 3

Chidori and her boss make a magazine research trip to a hot spring amusement park, and Ume (the girl of Chidori's bathhouse trysts, who she now knows is actually her boss's younger sister) decides to come along. The park is everything a hot spring enthusiast could dream of (who knew coffee baths were a thing?) but Chidori can't help feeling nervous as two very separate parts of her life collide. But there's also something else that's different on this trip, as Chidori's feelings towards Ume might be changing...
