朝起きると…隣に裸の同僚のみうが！？「昨日はすごかったね」と微笑むみう。何も思い出せない紗愛に、みうは昨夜のことを語り始める…。昨晩、泥●して記憶がない状態でノリノリでレズ堕ちさせられ、翌朝、お酒も抜けて記憶がないシラフ状態で抵抗しつつもまたレズ堕ちさせられる、ノンケには刺激的過ぎる2段階レズ堕ちセックス！そうして敏感BODYへと性感開発されたいとのカラダは、次第に自分からレズの快感を求め始めてしまう。

When Sae wakes up in the morning… her naked colleague Miu is next to her!? "Yesterday was amazing, wasn't it?" Miu smiles. Sae can't remember anything, so Miu begins to tell her about last night… Last night, she was drunk and had no memory of it when she was excitedly seduced into lesbian sex, and the next morning, sober with no memory of the alcohol, she resists but is seduced into lesbian sex again—a two-stage lesbian sex experience that is too stimulating for a straight person! And so, Sae's body, which has been sexually developed into a sensitive body, gradually begins to crave lesbian pleasure on its own.
