During a training camp, the promising athlete "Yukihono Uta" receives personal instruction from her coach. However, he has ulterior motives; his gaze is not on her athletic abilities but rather her feminine form. He drugs her with aphrodisiacs, causing her normally slender body to become aroused.

This leads to an endless orgy involving both men and the sweat-soaked woman, whose breasts are painfully erect as she experiences multiple climaxes due to the intense stimulation.
