Renya and Aya are a newly dating couple who work at the same beauty salon. Because of work, they don't often have the same days off, so they came on their first overnight date to a hot spring trip. After changing into yukatas and playing a penalty game of cards while drinking, perhaps because of the alcohol, the atmosphere gradually becomes erotic... The two who couldn't stand it went to the inn's private hinoki bath. In the changing room, they play pranks with their wrists tied with obi belts, and in the bath, they perform a periscope blowjob on their nipples that are visible through a wet towel, followed by a handjob that leads to squirting. The two who couldn't stop had sex right there, and then creampied. Thinking they were washing each other's bodies with bubbles, the uncontrollable horniness continued. They returned to the room and devoured each other in their yukatas.
