A pure and immature female student's body is pierced by twisted affection. Her innocent appearance—defined by undeveloped small breasts, firm buttocks, and a hairless pubic mound—loses its purity, transformed by distorted desires. Unable to endure the first sensations, she involuntarily urinates, even squirting streams of urine high into the air, losing her sanity as she drowns in pleasure. This depicts how an incomplete body is utterly dominated by perverse love.
