[NNPJ-323] Just turned 18! My slender girlfriend's little sister, Mika-chan, was too cute, so I secretly had her do an AV appearance for me. Nampa JAPAN EXPRESS Vol.94.
A pick-up artist who has been repeatedly rejected by his girlfriend (fuck buddy) for an AV appearance. At such a time, she introduced him to her 18-year-old sister. Because she was so cute, he secretly courted her and successfully had sex with her without her sister knowing. After that, he continued to secretly film himself having sex with her at her sister's house every day. When he became used to being filmed, he asked her to appear in an AV and she agreed to a 3P sex scene on the condition that her sister would never know.
