Sixteen year old and adopted mommy.
Mom never shut bathroom door when we were alone. I regularly saw her semi nude from behind for years. She was 54 with a nice plumpish figure. Obviously i masturbated for years watching her. One day being so frustrated i walked in on her suggesting i talc her back. She said oh son that would be lovely. My cock was so hard as i brushed against her bare buttocks.Couldnt stand it so i slipped off shorts and started to rub my bare cock up between her hips. She said oh son do you like that. I apologized but then she said dont be silly, you are normal and this is what a man does. She then to my amazement reached round, spread her buttocks and bent over the sink. Mom guided me in to her wet warm pussy saying isnt that good son. I said yes mom as i lifted up her slip and started to fuck her. Soon we were both cumming like a train. Mom then turned round and said you and i need to go to bed and we did and did for years after that. She taught me everything. We simply were both sexually frustrated.
Good for you
