A pick-up artist who has been repeatedly turned down when asking his girlfriend (fuck buddy) to appear in AV. Then, she introduced him to her just-turned-18-year-old sister. Because the sister is incredibly cute, he secretly hit on her and successfully had sex. After that, he continued to have hidden sex tapes at her house without her knowing. Once the sister got used to being filmed, he asked her to appear in AV, and she agreed with the condition 'Don't tell my sister,' leading to a 3P sex scene in an AV performance.
