Steamy Love

This is a yuri-flavored hot spring tour manga about an office worker and a junior high school girl.

Shiine and Ichika have just confessed their feelings to each other and became lovers. They go to an open-air bath together, only to see an H scene playing out between two women (from *Torokeru Joshiyu*). The naked girls find themselves in an awkward situation! (Source: Melonbooks, translated)
