The first time I met my girlfriend's sister, she was a dedicated athlete beauty. I felt an impulse to give the pure and innocent girl an aphrodisiac and play with her. I tricked her into drinking it, claiming it would improve her athletic performance, and the effect was immediate: she became drenched in sweat, her breathing grew heavy, and her eyes became glazed with pleasure. When I pretended to leave her alone, the innocent student-athlete, not even knowing what was happened, grew horny and began to masturbate with a random object...! After she reached a squirting climax through frantic masturbation, I immediately gave her a cunnilingus and inserted my huge cock into her now sensitive and awakened pussy. I creampied her multiple times in that hairless onahole pussy that squirted juices and reached climax in seconds!
