A secretly popular special course at a breast-specialized esthetic salon. A spiral of pleasure as oil is massaged deep into the areolas, nipples, mammary glands, and J-cup breasts! Twitching and throbbing! Drenched and sticky with slippery, glossy oil. Her ultra-sensitive J-cups, which feel pleasure just from friction, are fully developed. Through hand massage, she reaches a massive convulsion, arching her back in a breast orgasm!! "I can't forget that pleasure... I'm addicted to this lewd esthetic..." Only busty women are targeted, and they all fall for it.
