Quality time with my son

“Take them all the way off,” he said, his voice husky.
I stared at his fat cock, which was sticking straight up at me and throbbing in time with his heartbeat.
I kicked off my loafers and then stepped out of my shorts and panties, then took off my halter-top. My clothes now a pile at my feet, standing in front of my naked son, staring at his throbbing cock that was pointing up at me and seeing the look on his face, I was so excited and so very frightened.
“God, Mom, you’re beautiful,” he said. His voice was soft, and the look in his eyes was gentle, but filled with lust.
“Uh, you’re pretty handsome, yourself…I…” I stopped masturbating as a rush of guilt submerged my arousal.
He shrugged. “I don’t care, Mom.”
He took off his shirt and stepped out of his pants and shorts. He looked at me.
“Suck me,” he said.

I was shocked, crushed. My son shouldn’t have said that to me, it was something that I had caused by my lewd display. But to my shame I wanted to.
I took a few steps toward him and knelt between his legs. His cock was right in front of my face. His big balls hung low, and I reached up and cupped them in my hands, running my fingers over the velvety soft skin. I put my tongue right at that place where his cock met his balls, in those little folds of skin left wrinkled by the cock pulling the skin upward.
“Hey, lick my balls Mom, that’s great, wow,” he gasped. Shamefully I ran my tongue across one veined, hairy part of his sac, feeling the moving, egg-shaped orb beneath my tongue. Then, I did the same to the other half of his fuzzy nuts.
