George Spencer and I have been friends since we met at primary school. In fact, it was because of school that we met, as our homes are at opposite ends of the town where we live.

Over the years, we have just turned up at each other's place. We took to cycling the same route so we would meet each other if we chanced to try and visit at the same time.

On the last Saturday before the summer holidays, I bicycled over to see George. I went through the side gate, as usual, and parked my bike on the garage wall, then went to the kitchen door where I knocked, expecting to be invited in. No response, so I knocked again. At this, I heard George's mum say, "Oh, Richard, George is not at home."

I turned to see Mrs. S, as I called her, down the garden, kneeling on a blanket where she was sunbathing topless. I was stunned to see her bare breasts in full view. The image embarrassed me but also excited me, and caused my cock to stiffen.

"Go in, and pour yourself an orange juice. I'll join you in a moment."

I did as told and took the opportunity to sort out my stiffening cock that the sight of her naked breasts had caused.

A few moments later, George's mum appeared, wrapped in a short beach robe, poured herself an orange juice, and then ushered me into the sitting room, where she told me to sit on the large settee.

"Let's give these a bit of a kick," she said, indicating the orange juices, and giving each of them a shot of vodka. She then sat down next to me.

"George has gone fishing with his father, and won't be back 'till late this evening," she said.

"Did seeing my naked tits embarrass you?" she asked. I was surprised by the way she phrased the question, as I had always thought of her as a straight mum, although something of a MILF. Not knowing what to say, I nodded.

"Can I ask you some questions?" Again, I nodded.

"Has George got a girlfriend?"

"Not that I'm aware of," I replied.

"And you?"

"No, not at the moment."

"So, are my tits the first naked tits you have seen?" The question was so unexpected that I did not know what to say, and before I could respond, she added, "Would you like to see them again?"

Again, I was caught by surprise, so I simply nodded yes.

She immediately undid the tie to her bathrobe and let it fall open. Her breasts were now only inches away from me.

"Go on, feel them, they like being fondled.” As she said this, she grasped one of my hands and placed it on her breast.

"Squeeze the nipple.” I did as instructed, and she let out a soft sigh.

"I see you like what you are doing," she said, while indicating at the growing bulge in my shorts.

"I'm showing you mine, so you should show me yours," she added as she undid my shorts and pulled down the zip.

Released from the constraint of my shorts, my cock, poking above the waistband of my briefs, stood stiff and proud even as George's mum grasped it.

"Oh, Mrs. S, I …."

"I think you should call me Marie," she said, "in the light of what we are doing. Push your shorts and briefs off."

"Yes, Marie," I replied, and did as I was told.

"Kneel in front of me and pull my bikini bottom off."

I did as instructed and discovered that they were very wet, which I later learned indicated how excited she was. I also became excited as she slowly spread her legs and gave me a delightful view of her soaking wet cunt with her clit peeking out below her neatly trimmed pubes.

"Kiss it. Lick it dry, if you can."

I began with trepidation, but soon found that I liked the taste and, hearing her moans of satisfaction, I began to lick even more enthusiastically.

"That's right," she said. "Suck my clit, tease my cunt, tickle my bum hole. More, more."

All her dirty talk was getting me more excited. I got really turned on by her horny language, and she was obviously turned on by my sucking her clit and thrusting, first one, then two, fingers in her cunt.

She pulled my head and mouth hard against her spread legs, and a delighted squeal was followed by my face being soaked as she climaxed over me.

"Lovely boy, come here," she said as she pulled me up so that we were face to face. I was just conscious of the tip of my cock at the entrance of her cunt as her hands grabbed my bum and pulled me forward.

"Kiss me," she said. "I want to taste myself on your face."

Even as we kissed, I felt her cunt slowly engulf my erection. I became so excited that I did not last long, but Marie did not seem to mind, she only held me closer, and her cunt clamped around my cock, refusing to let it slide away. The result was that I became hard again very quickly.

Marie rearranged us so that we were lying full length on the settee, with me on top and her legs wrapped around my back.

"Fuck me again," she said. "I want to feel that big cock of yours give my cunt a good long pounding."

I began to do as instructed, but, now that the first excitement was over, I took a little more time and thought a little bit about trying to give pleasure to Marie.

"I do love horny boys like you," she said. "Every MILF's dream. A big stiff cock fucking my slutty cunt."

I was surprised by Marie's language, whilst at the same time being turned on by the bluntness of it.

"Do you like fucking my slutty cunt?" She told me openly what she wanted. "I want to feel your big hard cock make me cum," she said. Her talk encouraged me to respond in kind.

"I want to fuck you silly."

"I want to feel your cock give me a good shagging. I want to feel your cum soaking my cunt. Wreck me. Wreck me," she urged. This encouraged me even more, for I wanted to please her, and the way her cunt was gripping my prick and causing excited tingles in my balls pushed me to greater efforts.

"Is this what you want my cock to do?" I grunted as I thrust faster and faster.

"Yes, yes, I want to be your horny slut, play with my tits, suck my nipples.”

With her dirty talk, it did not take long before I was climaxing, and shooting my spunk into her welcoming cunt, as she came a moment later. I collapsed on her, and she hugged me close.

"You lovely boy," she said as we recovered. "We must do this again soon.”

The realisation that this was not going to be a one-off excited me, and Marie noticed.

"I see someone likes the idea," she said as she viewed my stiffening cock.

"How about coming for a sleepover with George the next time he and his dad are away on a fishing expedition?”

"I'd really like that," I replied.

"Good, I'll ring your mum about that. Now, lovey boy, I think you need to get dressed and pop home, and I will dream of your big cock giving me a good fucking.”

So that is what happened, and now I am waiting, impatiently, for Marie to ring Mum.
