One night when we thought our first son was asleep we started out having a great night...my wife ended up on top and just as we were both close to climax I heard my 2 1/2 year old son say "Yay! Ride em cowboy, Mommy!" He had snuck into the room, climbed on the bed, and jumped on my wife and played cowboy! We were both died! I put him back to bed, read him a story, and went back to my room...we then got the giggles and that ended our night...we now lock the door...
