A hidden camera captures the entirety of an adulterous massage that took place behind closed doors... "Teacher... I want to swim faster and get my best time!" In order to meet the expectations of the athlete, the cute female competitive swimmer's well-trained body is massaged and her vagina is gently massaged. The nipples that stand out in her competitive swimsuit are kneaded and twisted, and her pussy becomes sensitive and dripping wet at the end... Dozens of cameras are set up to secretly film her changing, going to the bathroom, and even her anus. The moment when the female athlete has a brain-bug vaginal orgasm.
