A couple who are usually very lovey-dovey and close go on a trip to a hot spring just the two of them. The two are excited to be back on a hot spring trip after a long time, so they go into a mixed outdoor bath and wash each other's bodies. As their skin touches in the hot spring, their excitement reaches its peak. Unable to wait until they return to their room, they end up intertwining in the outdoor bath. Even after returning to their room, their excitement doesn't subside, and they continue to burn with passion until the morning comes.
