As I stumbled upon my sister's intimate diary, I was taken aback by the vivid descriptions of intense pleasure. Determined to uncover the truth, I decided to put her words to the test. I confronted her, but she remained evasive, denying any unusual activity. However, I was relentless and eventually, she caved. With a mischievous grin, she led me to a secluded room, where she stripped down to her undergarments, revealing her perfectly hairless figure. She parted her legs, inviting me to explore her hidden desires. I obliged, diving in with my fingers and tongue, driving her to the edge of ecstasy. The sight of her, with her dress hiked up and her blonde locks cascading over the pillow, was a vision of pure pleasure. I continued my exploration, teasing her with my fingers and licking her to the brink of orgasm. The taste of her, the feel of her body beneath mine, was intoxicating. And as she climaxed, her body convulsing in pleasure, I knew that this was just the beginning of our shared secret.
