Reiya and Aya are a newly dating couple who work at the same beauty salon. Because of their jobs, it's hard to find time off together, so this is their first overnight date and they've come to a hot spring trip. After changing into yukata and playing a punishment game of cards while drinking in the evening, the mood gradually becomes erotic, perhaps due to the alcohol... Unable to contain themselves, the two head to the inn's private cypress bath. In the changing room, they tie each other's wrists with a sash and play around, and in the bath, they give each other a periscope blowjob with their nipples exposed through a wet towel, and then they squirt with fingering. Unable to stop, the two have sex on the spot and cum inside. Just when they thought they'd washed each other's bodies with foam, they couldn't stop getting horny. They go back to the room and devour each other in their yukatas.
