Stepson flaunts his large penis while I lie down, arousing me and leading to a mutual handjob

I was lying on my back, basking in the warmth of the sun, when my stepson strutted in, flaunting his massive cock. It was a sight to behold, a thick, throbbing member that seemed to command attention. I couldn't help but be drawn to it, my eyes tracing the length of his shaft. He noticed my gaze and, with a mischievous grin, he began to stroke it right in front of me. The sight of his fat, hairy cock sliding up and down was enough to arouse me. I found myself reaching out to him, my hand mirroring his movements as we engaged in a mutual handjob. The sensation of his skin against mine, the thrill of our shared arousal, was intoxicating. We continued our passionate exchange, our bodies entwined in a dance of desire and pleasure.
