Caught In An Awkward Position

In high school I became obsessed with masterbating and would do it any chance I had. I would usually wait until I was home alone. One day my mom was outside working so I went to my room and stripped down. I started jacking out while laying on my bed. I decided to prop my legs up on the head board and saw how close I was to my cock. I rolled back and flung my feet past my head so my cock was about 3 inches from my face and mouth. I kept rubbing and was about to bust when the door opened. I turned to see my mom. Her mouth dropped and I heard her say “what are you doing?” I tried to stop myself but it was too late. I started to cum and shot all over my face. It got in my eyes, nose, and mouth. I heard her footsteps leave my room. I flipped over and tried wiping the cum from my eyes. Then I heard her say here. She helped clean the cum off of me while I was completely nude. We never talked about it again.
