On some level I wanted to protest. It seems ridiculous that a big, strong guy like me was so powerless in that moment. I could have easily lifted my petite sister right out of the bed if I'd been so inclined. I could probably have carried her on my back for miles. It wasn't as if she was holding me down and forcing me to f**k her.
That instinctual urge to mate was simply too strong.
My c**k was sliding into a wet, tight, receptive little p***y, exactly as it was supposed to. It felt too perfect—too natural—once I was inside her again. We groaned in unison as my fat, throbbing d**k once more stretched her wide open. I stared at her beautiful face and watched her mouth open wide as I filled her p***y with hard c**k.
It was my sister's face, obviously, and that realization made me feel gui
