After our regular evening sessions with Robert, Mags and I would always discuss what we had done and how much we had all enjoyed it. Roberts mum Jean would often come into the conversation and we often discussed how we would love a foursome with her. We discussed it with Robert and he was all for it. Mags and I discussed a plan. This is what happened as told by Roberts Mum.
My name is Jean and I have an 18 year old son called Robert. My husband has been unwell and is incapable of fulfilling my sexual needs. As Robert grew up I noticed he was rather well endowed. Shortly after his 18th birthday I went in his bedroom to wake him. The bedclothes were off him and sticking out of his pyjama trousers was the largest erect cock I had ever seen. Although he was my son I was very turned on by what I saw. I couldn't take my eyes off it. I wanted to take it in my mouth and suck his spunk out of him. I felt disgusted with myself. How could I possibly have these thoughts about my own son. I quickly left the room and let him wake up naturally.
I went about my normal chores but couldn't get my earlier thoughts out of my head. I went to the local supermarket and found myself looking for the largest banana I could find. I had never done anything like this before. Then I'm in the next aisle and holding a cucumber in a very obscene manner. I couldn't believe what I was doing. I carried on with my shopping, having bought the cucumber and when I found myself looking at condoms I nearly went into a panic attack. I hurried to the checkout, paid for my goods and went to the car. Instead of putting everything in the boot of the car I put it on the seat beside me. I had a very strange tingling feeling between my legs and I could feel the wetness soaking into my knickers.
I fumbled through my shopping and found the large banana and the condoms. I knew had to abuse myself with it. I drove to a secluded corner of the car park and slipped my knickers off. They were soaking wet. I held them to my nose and took in the wonderful aroma of my pussy juices. I had just had to cum. Somehow I managed to drive home, all the while I had one hand in between my legs, slowly playing with my clit. I knew I couldn't cum until I got home as it would have been dangerous while I was driving. I dashed indoors. I knew I was going to be alone. I went to my bedroom and took the large banana and the cucumber and the condoms. I couldn't believe what I was going to do. This was not me. I do not do this. I occasionally play with myself but only use my fingers on my clit. I do not fuck myself with cucumbers and bananas.
But today was different. Today was the first time I had seen Roberts huge cock. Today was the day I was going to fuck myself and imagine it was my sons big fat cock that was fucking my cunt and making me cum. I quickly undressed. My nipples were automatically hard. I ripped open the condom packet and took out 2 of them. I slipped one over the banana and opened my legs. My cunt was awash with my cunt juices. It wasn't the time for being gentle and taking it steady. I needed a good hard fucking. I slid the banana inside as far as it would go. I started a frantic fucking motion. In and out as far as it would go. My nipples were hard. I wanted to play with them but I needed two hands to thrust my imaginary cock in and out of my cunt. I imagined it was Robert. I found myself saying, 'Fuck mummy's cunt, fuck your cock in and out of mummy's cunt, make mummy cum'. I lasted only about 4 minutes and suddenly I was cumming.
My juices flowed out of my cunt and how I wished it was Roberts cock and that he was shooting his spunk deep into his mummy's cunt at the same time. As my orgasm subsided I realised I was not totally satisfied. I needed more. I had left the banana embedded deep inside my cunt. I reached over for another condom and the cucumber. This time I was going to fuck myself senseless. This time the size resembled Roberts cock. If I could take the cucumber, I could take Roberts cock. I slipped the banana out of my slippery cunt and replaced it with the cucumber. I sighed with immense pleasure as the cucumber filled my cunt. I adored the feeling. It was so wide and so long. I was sure it was as large as Roberts cock. Again I wasn't gentle, I needed a good fucking. This time I called out as I imagined Robert was fucking his mothers cunt, fuck me Robert, fuck mummy's cunt, make mummy cum, shoot your spunk deep into mummy's cunt, oh yes Robert, you're making mummy cum, oh Robert, yes your making mummy cum.
My second orgasm was even more intense, and even after I had cum I carried on fucking myself and gave myself another 2 mighty orgasms. I collapsed on the bed. I picked up the banana with the condom still on it and slipped it into my mouth. How I longed it to be Roberts cock in my mouth. I wondered if I could fit it all the way in. I eventually recovered and had a shower. I decided to keep the banana and cucumber for further use and hid them carefully in my underwear drawer. The rest of the day I felt terribly guilty about what I had done. I tried to excuse myself by saying that if I hadn't imagined it was my own son fucking me it would have been alright. Robert and my husband Dave came home at the usual time and we had a normal evening. I awoke early already thinking about Robert. Dave got up and went to work. I dressed and then went to wake Robert.
I hoped I would see his cock again. I crept into his room. He was still asleep, but worse than that he was fully covered by his bedclothes. I felt the wetness between my legs. I silently went over to the bed and uncovered him. His erection was enormous. I sat on the edge of the bed and just looked at it. Suddenly Robert woke and saw me looking at him. I asked Robert if he knew why his cock was so large. He told me it was always like this first thing in the morning and didn't go down until he had a pee. I said there is another way to make it go back to its normal size and it feels good, would you like me to show you. He said he would. I reached out a grabbed his cock. I could only just get my hand round it. I loved the feel of it. He only needed a couple of rubs and I could feel the tell tale twitching as his orgasm approached. I put my hand over the top and soon it was covered in my sons wonderful cum. I told Robert he had had his first orgasm.
