Caught In The Act

I have had a secret sexual affair with my teenage step-daughter for several months now, since her mother goes to work early in the morning. We both have been exploring sexual orgasmic experiences together on a regular basis now. She is on birth control now so that we can fuck without a condom. It feels so much better to fuck raw and to cum deep inside of her. We both enjoy it so much better.
Anyways, one day my wife came back early to find me fucking her daughter. To make things worse, I was on the verge of orgasm when she walked in. It was all too much for me, and I exploded inside my step-daughter's pussy and pumped her full of many spurts of cum! I moaned out loud when I cum, and my wife heard it and saw it all. My cum was gushing from her daughter's pussy as soon as I pulled out. She was shocked, but did not say a word. She turned around and let us finish. I cum again inside of her after my wife left!
