Yuki, a 20-year-old man, begins masturbating with Mitsuki, who gradually leads him into heightened pleasure. Eventually, Yuki tastes Mitsuki's cock, fully accepting it until Mitsuki's dick penetrates Yuki's anus. Yuki moans passionately, eagerly sucking Mitsuki's cock with his mouth. Yuki finishes with a seated piston-style climax, while Mitsuki shoots a generous load into the condom. Afterward, the two collapse, completely exhausted.
