When no swimsuit model is arranged for the shoot, project manager Sayaka is forced to take responsibility by wearing the suit herself—but it is all a vile trap set by her department head. He exploits her mistake to pressure her into sex, while an aphrodisiac secretly slipped to her turns the humiliation into pleasure. Her huge breasts spill from the swimsuit, her thick ass strains the fabric, and the painfully tight crotch grows hotter by the minute. Eventually she embraces the obscenely revealing outfit and becomes a depraved model who actively begs for cock, conquered into complete submission by the stimulation.
