父の再婚で出来た義理の妹‘陽葵‘。第一印象は生意気だし最悪で絶対に仲良くなれないと思ったのだが、あることをきっかけに2人の関係は親密になっていく。そして妹に僕の彼女の存在がバレると「アンタ、陰キャのくせに彼女出来たんだ？どうせ経験ないんだし、挿れないって約束できるならSEXの練習相手になってあげる」とまさかのお誘い。そこからは性器同士を擦るだけ、1cmだけ挿入、先っぽだけ挿入とドンドン本番行為になっていき、遂にはモノ凄い肉体を練習台にしてガチ本番、セックスの快感に溺れていく！
My step-sister ‘Yo Aoi’ was born to my father’s remarriage. Her first impression was that she was cheeky, and she thought that she was the worst and that they would never get along, but after something happened, their relationship became closer. When my girlfriend’s younger sister found out that I had a girlfriend, she said, “You’re a secret guy, yet you managed to get a girlfriend?I don’t have any experience anyway, so if you promise not to penetrate me, I’ll let you practice sex with me.” ” and an unexpected invitation. From there, she just rubs her genitals together, inserts just 1cm, then just the tip, and the real action begins, and finally she uses her amazing body as a practice platform for real sex, drowning in the pleasure of sex!
