Former celebrity Koiki Nagisa takes on "Arousal Liquids" for the first time. She seems uneasy at the sight of the potent liquids. However, she's a determined girl. With the courage honed from years of performing, she gulps them all down in one go. Her body gradually heats up, leading to arousal and sweating. This time, she experimented with three different methods of ingestion: oral ingestion, steam inhalation, and applying oil to her skin.
