Caught in the act and rewarded by wife's sist

One night as I lay wanking away to porn on the TV, I must have dozed off as I was tired and been working all day. It was a Friday night and my wife had her sister staying over for the night.

The next thing I remember was a warm sensation around my cock as I was awakened. I was slightly startled to say the least when I looked down and their was my wife's gorgeous younger sister stroking and spitting on my cock. As I looked down, she looked up, my cock soaked in spit and she started to suck me off so hard.

It was unreal. She was running her tongue up and down my rock-hard shaft and I couldnt get enough of her. It was the best blow job I have ever had !!! She kept sucking and spitting on my cock before eventually asking " would u like to cum all over my face? ". I could barely answer her before she kneeled in front of me with her mouth open. Within seconds I had absolutely covered her face and filled her mouth with my warm spunk. The horny gorgeous little slut swallowed the lot and even asked me to spit in her mouth so that she could gargle my spit and clear her throat.

I still wank off thinking about it to this day........infact I think I may just now ?
