My new stepsister from my parents' remarriage is a beauty with a great body, but she's a high-maintenance girl who always looks down on a loser like me! Unable to contain my anger, I secretly started dosing her drinks with aphrodisiacs! As I observed her sensitivity going crazy day by day and played with her body, she started twitching and climaxing with extreme sensitivity! Furthermore, when I slammed my cock inside her, she became drenched in sweat and went crazy cumming, so as a reward for forgiving her, I gave her creampie after creampie!!
