Infiltrating a popular beauty spa in Gotanda, I found myself surrounded by stunningly beautiful female estheticians, each more gorgeous than the last. But one day, hidden camera footage from inside the spa leaked online—shocking videos revealing estheticians engaging in sex acts. Could this ordinary-looking beauty salon actually offer such services? To uncover the truth, I went undercover. My assigned therapist was a new girl, incredibly attractive with a flawless slender figure and exceptional skill. Yet everything about the treatment seemed strictly professional. But I wanted more. I aggressively pursued her, pressing until she could no longer resist—slowly stroking my erect cock, then whispering, "This is our secret," as she gently inserted it inside her. The entire experience felt like something truly forbidden.
