★SODstar graduation commemorative work★ Looks, sexiness, spirit, everything is the best with Koharu Shiina, a day trip to the hot springs. As soon as we arrive at the inn, we tease her with toys until her panties are soaked, and we have her body all to ourselves for the day. A private documentary of their bare instincts, as they clash with each other's bottomless sexual desires and repeatedly mate like beasts.
