Next her top and bra were off. I was kinda shocked, but still carried on. Then my boxers hit my ankles and I was told to lay down, at which point my j...ans n boxers came off.Next, amazingly, her jeans and thong came off, as well as shoes so she was absolutely naked. We were by now kinda hidden in a sunken dip, but only just out of sight. Our foreplay continued with her wanking me and me fingering her now wet swollen blonde pussy. Her lips were always swollen, but today they were full and deep in. Tasty... Was a boner and I'm hungry.- Don't talk like that... Dad... The mother!It happened, I knew it, we kissed, with him peeling his dick... I licked the bottom of my mouth, showed how I liked it, bit his tongue, feeling him jerk off hard. I didn't even look, I let that forbidden kiss roll with my husband's son, it was until I didn't resist. Still kissing... I grabbed the dick and rubbed it hard, squeezed the boy's cock, he moaned tasty at the bottom of my mouth, it even looked like had come. Now here was my own son using the same words, exactly the same words!"Where on earth did you get that phrase from?" I asked looking at my son more sternly than I'd intended."From a friend online," he smiled "sorry if it offended you mum." It was just a surprise." I laughed "Anyway, bed young man, goodnight Paul."In the kitchen sipping my chocolate I cursed myself for a fool for reacting as I had to my son's comment, it wasn't even an offensive phrase, but it was one I had thought was a shared. ”“NO!” I screamed. “I'll do it!”I couldn't believe the words had come out of my mouth. I couldn't believe she was asking me this.“Are you serious?” I asked.She smiled and jumped up on our old table and crossed her legs. She clapped excitedly and waited for me to come over and do it.“I can't wait to see how you do it. I heard that if you wrap something around your balls it will make you last longer. Do you want to try it?” she asked.“Whatever you like,” I said.“Cool, put this around your balls,”.
