GDHH-010 JK with sensitive nipples before her period gets groped

I asked an acquaintance who is a doctor to infiltrate a girls' school physical examination! Pretending to measure with a major device, I stimulated the cute nipples visible through her underwear and tormented her with a stethoscope! Although confused, the pure schoolgirl, sensitive due to being pre-menstrual or menstruating, gradually started to feel it. When I palpated her bare breasts, she created a stain on her panties! Furthermore, using the excuse of machine examination, I relentlessly tormented her vagina with a vibrator! Then, believing he was a doctor and unable to strongly resist, the pure schoolgirl ended up being penetrated!
