My mother, Kate, is in her fifties. She is just a little shorter than five foot five, has medium-length blonde hair, a very pretty face that could pass for forty, and a lovely voluptuous figure. She knows that men admire her figure and I see it at our work, with several regularly flirting with her. I'm not sure if she would ever do anything with any of them, but it's clear she could if she wanted to. She has large, sexy boobs that have always been one of her most striking features. She loves to dress sexily, especially in a dress or skirt. Her legs are thick and shapely, and her bum is just on the large side but perfect-- full, firm and rounded.
I'm her twenty-year-old son, Greg. I'm six feet tall and toned, as I am regularly at the gym working on my six-pack and arms that I need for my swimming. Mum regularly takes me to my meets, so has seen me in my Speedos many times, but has never thought anything of it. I have always appreciated my mum as a bit of a MILF, but one that someone else would fantasize over; however, over the last couple of years, things have become different between us.
A mother-son relationship that I have never thought of being sexually, but now, I cannot think of anything else. Even though I have several friends who are girls, I have never had a proper girlfriend, and I am still the only person to make me cum. I have dreamed of fucking lots of women, but I never had the opportunity. However, now, the one woman that is my fantasy is-- my mother, Kate.

I have always loved masturbating from a young age, and as I am usually playing with myself several times a day, it was only a matter of time until someone caught me. I had always tried to be subtle and to hide it, but on this occasion, I nearly didn't. I was lying in bed with my stiff cock in my hands, furiously jacking off, watching some BBW porn on my phone, when I heard the stairs creaking as someone was coming up. Within seconds, my mum was standing at the door with an armful of clean washing. I covered up and quickly got a book out, but I think she might have guessed.
"Greg, it's the middle of the day and you are back in bed, everything okay?" she asked.
I replied that I had just fancied a power nap, but she didn't seem to believe me.
She put the washing down at the end of my bed, and picked up a sock that was on the floor. "Is this dirty?" she asked, as she held it in her hand.
My heart sank-- that was the sock that I had cum in the night before, and forgot to put in the wash.
She squeezed the sock, feeling the crispy dry cum inside, and looked me in the eye. "Ah, I think this needs a wash," she said, as she quickly made her way outside of the room.
Although I was embarrassed, I was also really turned on by the incident; the thought of her touching my dried cum in her hand. How weird, but how horny? As soon as she left, I was straight back onto my cock until I exploded into the matching sock.
This was the first time that anything to do with my mum had turned me on, but I liked it... I liked it a lot.
I had two main places that I would masturbate; of course, in my bed, and the other was under my a blanket in the spare TV room. The room wasn't often used by my parents, so it was reasonably safe to pleasure myself there. I had a big, blue blanket that I would get under when watching TV, or porn on my phone, and jerk off.
On this day, I thought everyone was occupied elsewhere around the house, so I had some MILF porn on my phone, and had hidden myself fully under my blanket. With my boxers around my ankles, I was furiously wanking, when I heard a noise. I popped my head out, and looked down towards the foot of the sofa. Half blocked from view by my hard dick was... my mother.
She stood at the doorway of my sitting room, holding a cup of tea for me. She looked at it me, inquisitively. "What are you up to under there?" she asked smiling.
I froze. "Nothing," I replied, quickly.
"Yes, you are. Stand up and show me what you are up to," she demanded.
I couldn't say nothing anything; I tried, but nothing would come out. I just looked her in the eyes and held onto my still-hard cock.
She looked down at my feet, where my boxers shorts were, and then it all made sense to her.
"Oh sorry, sweetheart. Think you might be having a bit of 'you' time," she apologised, as she put the tea down and backed out of the room.
I was so embarrassed, but again, so turned on by being caught by her. What was going on? I had never thought about this, but the more I did, the more I wanted to one day masturbate in front of her-- in front of my mother. Looking her in the eyes as I was cumming was a fantasy that I desperately wanted to fulfil one day, but one that I knew she would never let happen.

Over the next few months, I would try to catch a glimpse of Mum, looking at her beautiful, round bum and had regularly started wanking while thinking of her. There was part of me that knew it was wrong, but a larger part that was so turned on by it. In the morning, I came downstairs into the kitchen, mum was alone tidying up from last night. It was clear from all the bottles out, that they had had a boozy night with friends.
"Would you like me to help you?" I asked, as I picked up some empty glasses.
