This video captures a hot spring trip taken with Reira, a college student. Being her first trip, we were both nervous at first, but gradually grew closer. The scene where she undresses for me in front of the outdoor bath becomes a special moment filled with both shyness and eroticism. Surrounded by the warmth of the hot spring, the act of entering her bareback feels intensely erotic and captivating. Included is an episode where, in our private setting and under the open atmosphere, I get carried away and end up creampieing her. This work conveys genuine, natural emotions that unfold effortlessly between us.
