After we ate our breakfast, we sat and talked to Granny for a while. I loved spending some time with her, but it was quickly becoming obvious that Mum wanted to talk to her about something and that I was the spare wheel, so I left them to it while I put our washing through the machine. I had a bit of a chuckle as I thought this poor washing machine has probably seen more cum in this load of washing than it had in decades prior.
When Chilton returned from his morning errands, he informed us that he would need time and privacy to do the physio Granny required each morning. Mum had already told me she intended to go into town to talk to a solicitor she had found locally. She wanted to do this alone, and I was feeling a bit at a loss as to what to do. As it was a nice day, I decided to look around the yard to see what needed to be done out there.
I pretty quickly discovered that there had been a lot of jobs that had gone by the wayside since Granny couldn't do them anymore. Gardens needed weeding; the lawns, although not overgrown, still needed mowing and edging. In fact, the more I looked, the more I saw that needed doing. I made a mental list and started by checking the shed for the tools required. I found the mower and a can of fuel pretty quickly, so I started with that.
By the time I had done the lawns, it had warmed up quite a bit, and I was sweating. I cleaned the mower and pushed it back into the shed and found some rubbish bags. I spent the rest of the morning cleaning up around the yard. I decided that the next big job to tackle would be to weed the gardens, but that could wait for now because I was hungry, hot, and thirsty. I went inside and cleaned up and was about to make myself something for lunch when my phone began to ring.
Seeing Mum's number made my heart rate increase, and I felt a smile spread across my face. Instantly I was transported in my mind back to this morning in bed. I felt my cock begin to swell at the memory, and I stepped back out into the yard just in case anyone from inside happened to walk into the kitchen.
"Hello?"
The voice that purred back down the line at me sent a shiver through me.
"Hello, my sexy, young stud."
She giggled like she had several times yesterday, and I realised that it was a sound that I had heard as a kid, but it never affected me the way it did now. Whenever I had heard it in the past, it was a sound of delight; now it had taken on a completely different and distinctly naughty tone. I wasn't going to let her have all the fun, though.
"Well, hello there, my sexy MILF."
"Oh, fuck, I love the sound of that."
"So do I."
There was a pause as we both thought about what exactly that meant, and I felt my cock harden even more.
"I was just walking around the supermarket trying to decide what to get for lunch when I had the very naughty thought of what I would really like to nibble on."
Oh god, this was so hot. I could hear the beeping of the registers in the background as well as the usual sounds of trolleys, people talking, and '80s music on the P.A. system. The fact that she was talking dirty to me while people moved around her in public was so outrageous and naughty that it made my cock ache for her.
"I can certainly think of something I would like to nibble on too."
"Mmm, good. I'm glad to hear that you're not the "take but not give" kind of guy. So, as I was saying, I was walking around the supermarket here, trying to think of food, and all I could think about was just how dangerously close we came to fucking this morning and just how much I enjoyed feeling your hard cock and your cum on me. Now I am so wet that my panties are absolutely soaked. What I want to do is take them off and play with my pussy, but even your slutty old Mum is averse to being arrested, so it might just have to wait until I am back in the car. I doubt I will make it out of the car park, though. Do you think that's too outrageous for your slutty old Mum?"
I smiled and practically groaned down the phone. I couldn't resist giving my cock a squeeze as I thought about it.
"First of all, you're not old. My cock is absolutely throbbing right now thinking about you doing that. I just wish I was there to enjoy it."
"Hmm, I bet you do. I want you to watch me too. I like the way you told me I'm not old but didn't say anything about me being slutty."
"I thought you were proud of being a bit slutty. I bet you want more than just me to watch you, don't you? I know you love an audience. I bet you want everyone there to see your wet pussy. You want them to watch as you slip your fingers inside your hot pussy and make yourself cum, don't you?"
"Oh, fuck. How is it that you know so well what turns me on and the man I married hasn't got a clue? I am so fucking wet right now."
"Show me."
"What do you mean?"
"You know damn well what I mean. I want to see how wet you are."
There was a long pause, and I worried that maybe I had pushed it too far. My cock was so hard, though, and I was glad I was out in the yard where no one could see me unless they came looking for me. I would hear the door open if they did, though, because the old timber screen door had a very squeaky spring hinge. Besides, being around this side of the house, I could hear the murmurings of Chilton and Granny talking in the room where they were doing the physio. I glanced around and realised that the neighbours could probably see me if they walked out onto their back patio, but at the moment there was no one there.
Then she whispered down the phone.
"You are so naughty, and I fucking love it. I have to go through the register now, though. I'll talk to you soon."
I reached down and slid my fly down, flicked the top of my underwear down over the head of my cock, and set myself free. It felt amazing to once again have the air caressing the bare skin of my cock.
A few minutes went by before I felt my phone buzz, and I opened the message.
"I know that you know this, but just a reminder that this absolutely has to stay between us. This is so wrong, but it's so exciting."
Attached to the message was a photo. It showed her standing next to the car with the door open. The open door of the car sheltered her from view in one direction and the car itself in the other direction, but directly behind her it was open to the back of the car park. There were several cars there, but I couldn't tell if there were any people in them. Most amazingly, she hadn't just lifted her skirt to flash her panties; she had removed both her panties and her skirt. She was completely naked from the waist down, and she was tilting her hips so that I could see her pussy. It did indeed look deliciously wet, and I was reminded immediately of how wonderful it felt to slide my cock along her wet slit this morning.
I had to be careful not to even touch myself for a few moments; I was that turned on. I took a quick photo to show her just how turned on I was. I sent it with the following text.
"Oh my God. It's so incredibly hot to see you doing that. I wonder if anyone was lucky enough to see you. You look good enough to eat right there where you are standing."
I gently stroked my cock as I waited for a response. Standing outside wanking was a big turn-on, knowing that the neighbours could potentially see, hearing the voices of Granny and Chilton from in the house, just a wall's thickness away, and seeing my mother's wet pussy was almost too much to endure.
Another message, but this time there were no words, just a short video. She was now sitting in the driver's seat, and I could hear the wet sounds of her fingers in her pussy. The phone jiggled about, and suddenly there it was, right in front of me. Her two middle fingers deep in her pussy as her thumb strummed her clit. The phone panned up, and I realised she had also freed her breasts from their confines. Her nipples were both rock hard, and she was smiling down into the camera. Her wet fingers came into view and began caressing one of her nipples, smearing her cum all over it. She then spoke directly into the camera.
