My Mum is a Slut Pt. 01 by rruk69..,

Everyone involved is over 18.

Thank you Dee for the rereads and editing.

****************************

Let me tell you about my mum. She is very nice, very friendly and very normal. She’s is pretty, keeps herself slim and she always dresses respectably. There’ll never be any cleavage on show or short skirts, and never wears anything you would call slutty or tarty.

She also has no sexy underwear, no stockings, no toys etc secretly hidden away. Believe me, I’ve searched. Every hiding place possible!

The one exception to this is her bikini’s. She has always worn bikinis, not swimsuits. I love seeing her in them sunbathing, wondering is she trimmed, hairy or shaven, although I very much doubt shaven. I would watch hoping for a glimpse of her tits or nipples whenever she turned over, or pulls the straps down for a better tan. The odd glimpse was all i got.

She’s doesn’t often go out; she doesn’t smoke and has never been a big drinker, maybe the odd one every now and then, but that’s it.

She’s never been wild or flirty or anything like that. I have never heard any of my friends say they fancied her, or wanted to fuck her, or she’s a milf, simply because she didn’t show off or expose her tits, flirt or anything else like some of the other mums do.

She’s just a quiet, normal everyday mum, or so I thought; but I was in for a rude awakening.

Oh, and she’s married to my dad.

She works hard and her work attire is normally a skirt and jacket or trouser suit, again all very covered up, normal almost prudish in the lack of flesh showing.

Recently, I learned to drive in her car. So, whenever possible I’d offer to drive her to work, then collect her at home time, giving me the use of her car in-between.

Lately, after dropping her off at work, she has told me not to collect her till later than normal as she had so much work to catch-up on, and the later, was well after her normal time and by the time I collect her, the other staff would be long gone. I never thought anything of it, and accepted what she said, as she’s often had to stay late over the years.

As the building is occupied by different companies, there’s all sorts of people coming and going. So, at the end of the normal day, the outer door to her area is locked. So, when I go to collect her, I must knock and wait.

A few times it’s taken lots of banging and even longer waiting around to be let in. She’s always apologised for the delay by saying, ‘sorry, I had some music on, or I was in the toilet’ etc; always something to excuse herself for not answering sooner. More than once she appeared to be very flustered, her breathing quite erratic, which was very unlike my mum. Once she even answered the door with her clothes a bit untidy, but it was the end of the day and you dont pay any heed.

Then one day my football training had been cancelled, so rather than go home, I headed to collect my mum. I knew I was early, but I didn’t mind hanging around waiting for her, maybe get her to finish a little quicker if I could.

Another reason was Joy, one her work friends who hopefully might still be there with her big tits and her tightly fitting and slightly too short dresses.

I fancied the arse off Joy, she wasn’t skinny, but wasnt fat either, so the tight snug dresses showed off every inch of her. The dresses were always above the knee. Not short, yet short enough for your mind to start thinking, mmmmmm. I wonder, does she realise what she’s doing, what a tease she is, especially to me!

Joy was my fantasy of fantasies, and many untold wanks. I fantasised about playing with those big tits, suckling her hard nipples, and fucking her senseless everyday.

But on this particular day, after what seemed like forever of waiting to get in, I knew I was extra early so I just gave up trying and was about to head back to the car and wait until nearer the agreed time, when I remembered the new raised flower and plant beds around the side of the building.

One side of the building has the offices, meeting rooms etc, and the other a long corridor.

Unlike before, maybe with the new raised beds meant I could jump up and see where she was and get let in.

So, I walked around to the side of the building where my mums’ offices were. I jumped up onto the raised planted edge and looked through the windows, trying to see her.

Finally, she walked out of a side room followed a few yards behind by a guy I didnt know.

I was about to knock on the glass and shout through the open window and point to the main door, when out of nowhere she bends over lifts up her skirt, flashing and wriggling her arse at the guy.

As she wiggles her arse, she pulls down her knickers, letting them drop to her ankles, then kicks them off. She then turns and drops her skirt just as quick to the floor and sits up on a nearby table.

I am horrified, dumbstruck and mesmerised.

My Mum then spreads her legs, holds her pussy lips wide open and slips a finger inside. She pulls it out, takes it too her lips and sucks it dry. She then just smiles at the guy as she watches him walk towards her. ‘You dirty bitch,’ I hear him say, smiling.

I can’t move! My mouth is hanging open. I stagger with the shock of what I’m seeing. It was the sluttiest thing I’d ever seen in my life, and it was my mum doing it.

Jesus Christ, my head wants to explode. I’m watching my mum offering herself on a plate to a guy in her office. She was behaving like some slut or whore. What the fuck is she doing? I’m shouting outside the window. But then realised I wasn’t banging on the glass, or shouting out loud, it’s all in my head and I’m just watching with my mouth open.

My cock is getting harder by the second as I start rubbing it. Without thinking I get my cock out and begin wanking.

What I really should be doing is banging on the glass, shouting at her to stop, but no, I am watching while my mum is about to let this guy fuck her and the sluttiness of it all clearly wins out.

The guy drops his trousers bringing his hard cock to my mother’s open cunt. Even I can see she’s ready. You can see how wet she was even from where I was standing and her lips are wide open, which made me wank all the harder.

I want to get closer, but I know, if I lean against the window, they’ll see me. So, I stay back a little in the early evening darkness, the reflection saves me. I am about watch my mum get fucked; and not by my dad! And i have the hardest cock I have ever had in my life. What the fuck does that make me?

He wants her to suck his cock, but she tells him they don’t have time, as I am coming to collect her soon.

He tells her he wants to fuck her mouth, to watch his cock disappear down her horny throat. I can’t believe what I am hearing being said to my mum.

Instead, she pulls at his cock, aiming it at her needy cunt. Clearly, wanting it up inside her. She tells him she’s going to suck his cock clean once he’s fucked her. This had the desired effect and he starts to slowly rub his cock up and down her pussy lips.

She is begging him to fuck her, that the teasing is too much. He places the end of his cock just inside her cunt, but then only very slowly pushes in. My mum wraps her legs around his waist using them to pull him deeper into her pussy. Pulling him more and more towards her, desperate to get his cock deep in her cunt.
