He continued to moan and murmur, nothing coherent yet. But whatever had his brain ticking was influencing his penis. It began to visibly twitch. Then it began to swell considerably, with more frequent twitching and pulsing. It wasn't long before he was fully erect. His knob reached past his belly button as he lay there, legs spread, on his back. He was so hard that his cock wasn't even resting on his tanned smooth stomach, he was rigid hovering in the air. He continued to murmur and his cock was twitching even more now, I could see the precum oozing from his knob, forming a cobweb attached to his stomach, getting longer and thicker the more precum oozed out.
I realized that my finger was tracing my pussy lips in my panties. I was still salivating as I watched the thickest, most muscular cock I'd ever seen bouncing up and down over my son's muscular body. I pulled my panties to the side and let my fingers slide effortlessly between my wet lips to find my clit and begin massaging it greedily. I was oblivious to anything around me as his cock began to throb more aggressively and more frequently, my son was murmuring louder now, his muscular legs began to flex as did his butt, forcing his balls to raise and lower in time with his muscular contractions.
Just as my fingers entered my pussy, his cock twitched hard and high off his body and exploded! A big thick streak of cum shot from his glistening knob and landed on his strong smooth chest, then another, and another. His cock continued to throb and spurt thick creamy cum all over his chest and abs. Eventually, his orgasm dissipated, his cock going still and noticeably softer but still long and thick, it came to rest on his thigh again, cum oozing from the tip over his hip and onto the bed.
His murmurings went silent, his body looked relaxed and calm now, but my fingers were anything but. They were feverishly fucking my tight wet pussy hole. I was so disgustingly horny, I didn't care what I had to do to orgasm, I was going to do it right there. Watching my sons cum covered body and cum oozing cock get me there, I had to bite my lip hard as my body convulsed so violently my knees slammed into his door as I leaned against it. In a panic, I slammed the door shut and ran back to my room. I have no idea if my son woke up or not and saw me, but I didn't care, as soon as I was safely in my room, I retrieved my biggest dildo and fucked myself to orgasm over and over, still salivating at the thought of all that cum, the thickness of his immense meat. Craving it, wanting to taste his creamy cum and feel his thickness inside me.
