名門ウィンホール聖桜学園、仙夏朔夜。
学生会長で、全学生が憧れの眼差しを送る高貴な白百合のような存在。
しかし、彼女には秘密があった。
それは露出癖、見せること、見られることで快感を得てしまう性癖。
肉体の疼きに掻き立てられて、バレるかバレないかの瀬戸際を攻める淫靡な露出プレイは日毎にエスカレート。
学園内での自慰、深夜の露出散歩、ついには自分を慕う後輩を巻き込んでの性行為へ。
周囲の人々の驚嘆と侮蔑の声さえ、媚肉を火照らす刺激へと変わり、羞恥による享楽の底なし沼へと沈んでゆく。
「さぁ、参りましょう。淫楽の深淵へ！」
Senka Sakuya from the prestigious Winhall Seio Academy.
She is the student council president and is like a noble white lily that all students look up to with admiration.
But she had her secret.
It's her exhibitionism, her tendency to get pleasure from showing off and being seen.
Aroused by the aching sensation in her body, her lewd exhibitionist play escalates day by day as she approaches the brink of being found out or not found out.
He masturbates at her school, takes a late-night walk exposing himself, and finally engages in sexual activity with his junior, who admires him.
Even the voices of surprise and contempt from the people around her turn into stimulation that lights up her aphrodisiacs, and she sinks into a bottomless pit of pleasure caused by shame.
"Now, let's go. To the abyss of lewd pleasure!"
