The younger sister I met at her house was a tomboyish club athlete. Her healthy, toned body and handsome features were incredibly attractive. I bought some aphrodisiac wanting to use it on her but she refused, so I mixed it into the protein powder of her younger sister to see what would happen. The aphrodisiac worked like a charm; she quickly became drenched in sweat, her breath grew ragged, and her eyes glazed over. The innocent club girl had no idea what was happening to her and just kept getting more aroused. I rubbed my erect penis against her wet vagina and teased her by inserting only the tip 1cm deep, driving her crazy. Then she said, 'Please, put it all the way in...!' Alright! She said it! Let's make her sister a sex maniac and turn her into a fucktoy! It's not cheating because her sister begged for it! As soon as I inserted my huge cock deep inside the awakened athlete sister, she came instantly! Her abs flexed so hard she arched her back, rolling her eyes back in ecstasy, so I couldn't help but cum inside her multiple times!
