Alone together in the outdoor hot spring, the atmosphere feels different from our usual routine. She seems a bit shy at first, but her body gradually responds naturally, and before long, things turn erotic. Since making noise might alert others nearby, she stifles her moans while growing increasingly aroused. Perhaps because of this, her lubrication steadily increases, heightening her sensitivity. Responding to her reactions, my excitement builds rapidly, until finally I thrust deeply and finish with a creampie. Somehow, having sex in such a special place feels even more intense than usual.
