A total of 10 female students in gym uniforms are subjected to the insidious harassment of perverted men in white coats. The nipple harassment physical examination begins. The real doctors are tied up, and men disguised as fake examiners appear. Lewd questions are repeatedly asked to the girls struggling with adolescent worries. "When was your last sexual intercourse?" "How often do you masturbate?" The girls can't shake their doubts—"Do you really have to ask that?"—but reluctantly answer, their expressions the very picture of shame.
As a matter of course, their bras are removed, and they undergo 'Nipple-hardening chest measurement,' 'Nipple-kneading diagnosis,' 'Licking-and-erect-nipple measurement,' and 'Boob-squeezing comparison measurement.' Letting out breaths, the girls' weak nipples react sensitively and secretly climax. Their pathetic nipples are toyed with endlessly, leaving them sensitive and aroused. The examination then progresses from 'Pubic hair check' and 'Butt shape & squeeze-feel measurement' to an 'Anal-exposing pinworm test' where they must spread their own anuses. When the 'Vaginal temperature measurement' with official fingering is performed on their pussies, now moistened from forced humiliation play, it's a shock. Even with friends watching nearby—or perhaps because they're watching—the shame, pleasure, and stimulation to the vagina become unbearable, causing them to lose control and urinate. The urine is carefully collected in a specimen cup. Then, when the fingering stimulation is intensified, this time they gush a massive squirt. This too is carefully preserved, and we'll go on to examine the mysterious fluids.
Now the fake doctors are also at maximum arousal and can't hold back any longer. "This is just an examination, so there's no worry about pregnancy or anything!" they say, as they insert themselves one after another into the innocent pussies. "This is wrong... I'm going crazy from the pleasure..." The ultimate shame of being watched by friends eventually flips into exquisite pleasure, their sensitivity skyrocketing, and the girls are unable to resist the onslaught of ecstasy. They're even subjected to re-examinations, progressing from irrumatio to 3P skewer creampie fucks. The total of 10 girls, unaware they're dealing with fakes, are deceived by the lecherous men, their precious nipples toyed with endlessly, and unable to resist, they're fucked over and over and filled with cum. The health check room, the examination venue, transforms into a bizarre space echoing only with the sounds of sex.
