Yard work

As i mentioned earlier my name is Jack I am just an average guy, including penis size. I do workout regularly, but im not a hunk by any stretch of the imagination, so if i were to be in a situation where i was naked in front of a woman other than my wife, it would be very humiliating. My mother in law who lives with me and my wife is in her early sixties. She has a slim build and has a good figure for a lady her age. Being an average guy, i do average guy things like work and then come home to work some more, like yard work. I live on 20 acres and have a large garden and lots of grass to cut. Maintaining my property is like a full time job by itself. One saturday while mowing the lawn my worst fear happens, i run over a bees nest in the ground. In an instant, im off the lawn mower and starting to come out of my clothes. Little did i know, the whole thing is being witnessed by my mother in law who is sitting on the back porch smoking. Before i know it i am naked running towards the house, getting stung EVERYWHERE! It takes a second for me to realize where the laughter is coming from, but I look up and realize that my mother in law is laughing hysterically at my butt naked show. I am horrified to say the least. Now I am in a predicament.
