‘びくっ！！’（今…お尻に何か…。電車混んでるし、ただぶつかっちゃっただけだよね…？）平穏な日々を脅かす突然の非日常。美少女で押しに弱い学生は痴●され放題。‘ビクッ！！’（私ってもしかして変態なのかな…？）未経験の快楽に声が漏れないようにするだけで必死。敏感で無言のまま感じてしまう学生は狙われ放題。‘ジョロジョロジョロ…’（お漏らしなんて恥ずかしい…見ないでっ…）’痴●’という言葉すら知らなさそうな美少女は電車内での快楽行為に純粋な気持ちでのめり込んでいくー。

'Gasp!' (Something just touched my butt… The train's crowded, so it must have just been an accident, right…?) A sudden, extraordinary event threatens her peaceful days. A beautiful, easily swayed student becomes a target for sexual assault. 'Gasp!' (Am I a pervert…?) Desperate to keep a sound out of her mouth as she experiences unprecedented pleasure. A sensitive student who feels everything silently becomes an easy target. 'Drip, drip, drip…' (It's so embarrassing to wet myself… Don't look…) A beautiful girl who seems to know nothing about sexual assault becomes innocently engrossed in the pleasurable acts on the train.
