I introduce my anal-loving friend to my stepsister and guide her through the dating process

As a seasoned lover of all things taboo, I've always been drawn to the thrill of anal sex. When my friend expressed his interest in joining me, I knew I had to introduce him to my stepsister, a slender 18-year-old with a tantalizing ass just begging for some action. Upon meeting her, I sensed a kindred spirit in my friend, and I knew he was the perfect match for her. I guided him through the dating process, helping him win her over with his charm and raw sexuality. The moment finally arrived when they were alone, and he wasted no time in showing her his true intentions. As he undressed her, I couldn't help but be captivated by the sight of her petite body and inviting ass. I decided to join in, taking turns with my friend in exploring her tight, round ass. The sight of her getting pounded from behind by my friend was a sight to behold, and I found myself lost in the moment, enjoying every second of it.
