Mitsuri Nagahama gives her inexperienced adult student a private lesson in kissing. She gently invites him closer, teaches him to extend his tongue, and tangles tongues and saliva in slow, dirty kisses. Using her seductive technique, she guides the virgin student all the way to ejaculation before showing him what an adult kiss truly feels like, leading into saliva-soaked kissing and sex. (adult teacher-student role-play)
