I want it too...

My hand dug into Kaila's hip, my fingers, curling into the hard edge of her hipbone and teasing there. Kaila groaned deeply at the pressure.

"Oh fucking... take it..." She gasped, her cheek now pressed against the stone. I slipped one hand to the small of her back and pressed hard, angling her just a little more comfortably as I continued to shove into her over and over, pressing her between me and the hard surface.

My wife felt so good, so ready, so... I couldn't believe she was willing to do this for me. Ever since I had moved in with her and her sister, the understanding had been that even mentioning this was... fucking Carla... oh shit...

I felt my self unable to contain the idea that it wasn't my wife on the end of my cock, but my wife's sister. The thought of sisters naturally brought Imogene's face to my mind, and as my wife moaned ardently, I couldn't help but picture Imogene under me the same way that Carla...

The thought of fucking Carla, another forbidden but so eagerly wanted fantasy was the final spark that caused the flow of come to begin. I felt myself tensing as I rammed into Kaila hard and as deep as I could. The first pulse through my rampant cock almost caught me unawares with its intensity, and I felt the soothing ache as everything I had emptied into the woman gasping on the boulder. My wife... her sister... my sister... they all seemed to flow into one as I pumped again and again into Kaila...

I felt rivulets of sweat running down my face as I came back to reality and realized that I had just been loudly fucking my wife in the open. I panted, slowly sliding back from my wife, my cock flopping free of her. It was followed by a small dollop of my come running down between the lips that concealed her incredibly pleasurable and welcoming vagina.

"We... oh shit... we shouldn't have done that." Kaila giggled against the boulder. "Fuck... my face is gonna be totally scratched up... ack. How bad does it look?" She rolled to the side, her bare lower body an instant draw to my attention. She pulled her feet up as she did, pulling her jeans and panties up her legs with a quick motion. Her face... well, there was definitely some pressure there. Looks like she had done a faceplant, but no scratches or anything permanent. Just looked like she had pressed her face against a wall for a while.

"Not too bad, Kaila" I smiled at her, my hands tucking myself away. I loved the feel of a woman on my cock. Even if it was only for a little while, the last thing I wanted to do was get rid of the sensation of her on me. Course it didn't hurt that it was my wife, and... I loved her. No, our marriage wasn't perfect, and we had our issues, but Charlotte had been absolutely right. We both needed to ask for what we wanted.

"You..." Kaila opened her mouth softly. "Okay, you were just playing. Almost... well, almost thought you were serious there for a second."

Kaila adjusted her hips, pulling her panties and jeans up one at a time, and once again concealing herself from the world at large's gaze. It almost made her even sexier as she did the final adjustments, turning once again into the gorgeous woman I fell in love with. Knowing what had just transpired between the two of us... yep, we had just had our make up sex session...
