The younger sister I met at her house is a boyish club athlete. His healthy, toned body and handsome face were very attractive. I had an aphrodisiac on hand that I wanted to try on my girlfriend, but she refused and I had nowhere to go, so I mixed it with protein and gave it to my girlfriend's younger sister. The effects of the aphrodisiac were so strong that I quickly became sweaty, breathing heavily, and my eyes became sharp. An unsuspecting, innocent club girl becomes lustful without even knowing what's happening to her. He placed his erect penis into her slimy pussy and inserted just 1cm of the tip, teasing her until she had a headache. Then, "Oh, please insert it all the way...!" Okay! Said! Let's continue to pickle her sister and turn her into a meat urinal! It's not cheating because it's a plea from my sister! When I insert a big dick deep into my sensitive and aroused athlete sister, she cums in seconds! I was cumming so much that my stomach muscles were cracking and the whites of my eyes were exposed, so I couldn't hold back and cum over and over again!
