The first time I met her younger sister, she was a beautiful athlete who dedicated herself wholeheartedly to her club activities. I was seized by the urge to play a prank on her innocent sister by giving her an aphrodisiac with aphrodisiac effects. I tricked her into drinking the aphrodisiac by telling her it would improve her athletic performance, and the effect was immediate. She quickly became drenched in sweat, her breathing became heavy, and her eyes became hazy and glazed over. I pretended to go home and left her alone, and the innocent club girl, unaware of what was happening to her, became aroused and slowly began to masturbate with a foreign object...! As the little sister masturbated frantically and came squirting, I immediately gave her a cunnilingus and inserted my big dick into her sensitive, awakened pussy! I cummed inside her shaved pussy multiple times, and she came instantly, squirting profusely!
