Since a swimsuit model could not be arranged, the planning staff member Ayumi was made to take responsibility and wear a swimsuit herself to act as the model. However, this was a despicable trap set by the department head! He took advantage of her mistake to force an unreasonable physical relationship upon her. But before she knew it, she had been slipped an aphrodisiac, causing her large breasts to spill out from her swimsuit and her plump buttocks to be emphasized in a way that couldn't be hidden, while the heat between her legs turned into pleasure... She ends up falling into becoming a perverted model who shamelessly wears obscene swimwear and seeks out penises!
