Thinking that it must be her lover, Masaru immediately rushed into the fuck again. But he was wrong again, this was still Himari who had just finished taking a bath! Even so, Masaru couldn't stop and poured all the sperm he had accumulated into Himari. While thinking about how to solve this matter, Himari approached you, seducing you, wanting you to come inside her more and more...
