I've been fantasizing about my stepsister's boyfriend for a long time. His cock is a behemoth, and I've been dying to see it in action. When my step-sis went out for the day, I couldn't resist the temptation any longer. I found myself in her bedroom, admiring her boyfriend's impressive member. But that's not all he had to offer. He was more than willing to help me satisfy my curiosity. The sight of his big, fat cock made me weak in the knees. I eagerly took him into my mouth, savoring every inch of him. But that wasn't enough. I wanted to feel his hard cock inside me, and he was more than happy to oblige. He took me from behind, fucking me hard and deep. It was an experience I won't soon forget.
