My sister, at the age when she began to yearn for adulthood, was coaxed by her brother who, after putting a love potion in his mouth, gave her a thick kiss! Unaware, she swallowed the love potion, her body heated up and her sensitivity skyrocketed! Then, reaching for her soaked vagina, she made her feel it over and over. With the effects of the love potion, her sister completely lost her reason and when inserted... she surrendered to pleasure, shaking her hips wildly, transforming into a highly lewd and eager to climax!
