My stepsister's disbelief of my size leads to a steamy encounter

As a young lad, I've always found my stepsister's disbelief in the size of my package quite amusing. She would often tease me about it, but deep down, I knew she was secretly yearning for more. One fateful day, after a heated argument with her, I decided to prove her wrong. I unzipped my pants, revealing my monster cock to her awe. Her eyes widened in shock and arousal as she saw my impressive member. Despite her initial shock, she couldn't resist the urge to suck on it. The sight of her small tits and big ass, coupled with her petite frame, was a sight to behold. As she eagerly took me into her mouth, I knew I had to have her. I lifted her up and slammed her on the couch, her moans echoing throughout the room. The taste of her hairy pussy still lingers in my mind, making me crave for more.
