Almost caught!

This happened in our first year of marriage. I was in bed, the wife on the couch not feeling well. So the urge hit me. I dropped my underwear, and began to play with my soft dick. It did not take long to get a rock hard cock. I had never admitted, or been asked if I masturbated. Anyway i was well into my session and ready to blow my load, when the bedroom door opened. I gripped my cock so hard, to hold my cum in. All that my wife needed was some pajamas. She took the pj's out of the dresser, and was gone. I released my grip on my cock and stroked it just a few more times a blew one of the biggest loads ever. Man the thrill of almost getting caught. We are now well into our marriage, and both know what goes on behind closed doors!
