Parts 1 & 2 are in my recent posts. You’ll find them if you click on my username. You can read this as a standalone, but it’s probably better if you read them in order.
Anyway, the story…
Becky had been on top of me, but after her orgasm courtesy of my mouth, she had slid off me and was lying by my side. I could feel her hair spread across my thigh, could still feel the sensation of her mouth and throat around my now deflating cock.
We lay like that, brother and sister side by side in the darkness, probably like countless other siblings had done before. The only difference was that I doubt many of them would have had the taste of each other’s cum in their mouths. Or maybe they would have. I was finding out a lot of things about my big sister that night that I hadn’t even dreamed would have been true before she told me.
“Becky,” I said, turning on my side and stroking the side of her thigh. “What did you mean by that? What is it I don’t know the half of?”
