My sister surprised me with a visit from her new boyfriend, but it wasn't long before he was teaching her the art of pleasure. I couldn't resist joining in, guiding her through various positions until she was fully satisfied.
My sister has always been a bit of a wild child, and when she brought her boyfriend home for the first time, I couldn't help but notice the size of his impressive cock. As soon as they were alone, I overheard her whispering to him about how she'd never seen anything like it before. It was clear that my sister was struggling to please him, so I decided to step in and teach her a few tricks. After some initial hesitation, my sister was eager to learn and started practicing on me. She took turns riding me in cowgirl, doggystyle, and missionary positions, all the while asking for feedback and adjustments. But the real test came when her boyfriend arrived. With a mix of nerves and excitement, my sister put her new skills to the test, and to my surprise, she managed to please him quite well. It was a thrilling experience to watch as my sister, who had once struggled with his size, now confidently handled him with ease.
