I was 15 and I was spending the night at my friend's house. My friend's mom would get up early and jog and then shower in the basement as not to wake up my friend's dad. I had gotten up early, before my friend, and was in the kitchen. She walked up from the basement wearing a towel. She was walking through the kitchen, when she saw me and was startled. She jumped a little and her towel fell off giving me a full frontal. She quickly picked it up and held it in front of her. She then quickly walked down the hallway to the bedroom, exposing her lovely hot naked butt the whole way. My friend never found out and things were very awkward whenever I saw his mom.
