大学パンフレットにも載った有名私大チアリーディング部所属の美少女、杉山ちひろさん。キュートな笑顔＆チアガールならではの引き締まった体、下ネタの付き合いも良く、学内でもモテモテ。そんな彼女をAV出演させるべく、スタッフがじっくり時間をかけて彼女に接近。彼女が脱ぐまでの日々を追ったがちんこドキュメント！Chihiro Sugiyama, a beautiful girl on the cheerleading squad of a famous private university. You could even find her in the college pamphlet! She has a cute smile and a body befitting a cheerleader, and she's very popular on campus for her down-to-earth attitude. Our staff took their time to really get to know her and get close to her, all in the effort to get her in the porn shoot. This is a genuine documentary of the events leading up to the day when she finally agreed to take it all off!
