優等生の「ひなた」には誰にも言えない秘密があった。帰り道にある鉄塔でおじさんを待つ事から「ひなた」の淫らな放課後が始まる。男根をしゃぶりつくし、痴態を晒す事でしか自分の存在価値を確かめられない。純朴な顔立ちだが、脱ぐと見事な若さ溢れるピチピチボディ。学校では決して見せれない優等生の裏の顔。Hinata, an honors student, has a secret she can't tell anyone. On her way home, she waits for her uncle at a street pole, and that's when Hinata's lewd after-school activities begin. Her only way of feeling alive is by sucking on a man's cock and exposing her slutty-ness. She has a simple face, but when she takes off her clothes, her body is full of youth. This is the face of an honor student who can never be shown at school.
