I am an only child brought up by a single mom as dad left when I was 10 and has never come to see me at all since. When I was 16 I had left school bought a moped and was working at an apprenticeship. I was also constantly horny. At about this time I started fantasising about my mom and would often wank my cock imagining that I was fucking her my mom was 18 when she had me so was not that old and still had a great body.
My mom is a teacher and so did not go out much really as she would spend her evenings marking but she used to go out on saturday nights and sometimes on sundays too and used to tell me she was visiting some relatives but one day I met my aunt in town and said she had not seen mom in ages so I knew she was lying and decided to see where she went.
That saturday it was a nice evening and at about 8 pm mom went out, as soon as she left I followed her keeping back a bit so she would not see me, she drove away from town to some woods about 2 miles from our house which had a car park. I parked my bike in the trees and crept up to see what was happening. I saw my mom had parked her car and wound the windows down there were 2 other cars there and in one I could see a man and woman were fucking on the back seat while 2 men watched and wanked their cocks. I was amazed and soon had my cock out and was wanking as I watched, then mom did something incredible she got out of the car and took off all her clothes, it was beginning to be a bit dark but I could clearly see that she was naked and standing watching the couple and the other guys. As I watched another guy walked over towards mom with his hard cock in his hand stopped in front of her wanking that cock and mom just knelt down and began sucking on him soon she was leaning back over the car bonnet being fucked by this perfect stranger within minutes he had cum and pulled out of her I could by the light of the cars interior light see his cum dribbling from her c**t. As she lay there one of the guys from earlier came over and turning her round began to fuck her doggy style. I crept a bit closer and could see him banging in and out of her and hear her saying yes yes fuck my slut c**t, I couldnt stop myself I pulled the visor down on my crash helmet and pushed my cock at her mouth, she did not even look up at me just swallowed my cock. It took me only about 2 minutes before I was cumming in her mouth, as soon as I had I walked away and went home.
About 30 minutes after I got home mom came in, I did not say anything to her just walked up to her and kissed her slipping my tongue into her mouth. She was shocked and said what the hell do you think you are doing. I just smiled at her and said just seeing if I could still taste my cum in your mouth. At that point she realised who she had sucked off in the woods.
