Mum Lets Her Slut Loose

All characters are over 18. Lots of incest and piss.

In a single weekend, my life with my mother went from a gentle drunken tease to the dirtiest erotic sex. We explored and learned about each other for some weeks before we settled into regular, still dirty sex.

Here are a few highlights of our explorations.

Mum was swimming in the pool in a slinky yellow one-piece. She got out to accept the cold drink I'd made her. I watched the pool water run down her legs, looked at her pussy stretching against the fabric. We chatted, she dried off, and without any word of warning mum simply sat on my lap and pissed through her swimsuit, all over my thighs. She was giggling like a naughty schoolgirl, and of course I didn't mind one little bit. But it started a new chapter in our incestuous affair. We would do things with, and to each other spontaneously, sometimes in the presence of others, although we were careful that nobody would ever know.

On a near-empty train one day, on the way back from visiting family, I was dozing against the window. I felt soft, warm fabric against my face and a scent I had come to love - my mother's pussy scent. She'd taken her panties off and put them on my face.

I looked at her through one open eye: "Really, mum? Now?"

"Yes now. Get your cock out, I'll sit on it and fuck you. You don't even have to wake up if you don't want."

"As if I could sleep through that!" But I got my cock out, mum sat on it as promised, and rode me for a few minutes until she came. We passed three stops, nobody got on our carriage, but I hadn't cum.

"Let me suck you then, baby."

"Mmmmngh! Shit, I'll never get tired of your mouth on my cock!"

She sucked me, and when I was close, I said: "Give me your tits."

She pulled them out of her top, aimed my cock, and took my load on them.

Just minutes later, two noisy couples got in our carriage. We acted as if nothing had happened. Mum leaned in close, nibbled my ear, and whispered: "Should I tell them I've got my son's cum on my tits?"

"Might not be a good idea."

"OK, it's our secret then."

A crowded department store. I know when mum needs the toilet - apart from a few giveaway gestures and wriggles of her hips, she usually tells me because she knows I love everything about her pissing. And she's smart enough to keep me erotically charged by teasing me, treating her bodily function as a treat to be savoured.

She grabbed my arm and ushered me toward the toilets.

"Hell mum, I can't go in there. We'll get caught!"

"We're not going in there. C'mon."

She led me past the toilets, past the cleaner's room to a heavy steel door with a bar across it. She pushed the bar, opened the door, and pulled me into the bright sunshine. Outside was a little grotto, walled on all four sides, full of broken pallets, an old plastic mannequin, broken displays and such like. After closing the door, mum leaned against it, pulled her dress up to show me her virginal-white panties, and pissed through them. It ran down her thighs into her sandals, pooled on the step beside the door, then ran over the edge onto the dusty ground.

"Mum, stop."

"OK. But why? Oh..."

She knew the answer when I put my hand over her soaked panties and rubbed. The fabric was so wet that I could feel the nub of her clit under my fingertip, and I knew by now how she liked to be masturbated. So I made her hold the rest of her pee inside, until I was ready for her to release it.

"I thought you might just want to watch me wet myself, baby."

"I do. But I want to feel you as well."

She held her dress under her chin, and warned me: "Here it comes, baby. Don't get it on your jeans."

I stood to one side as my mum peed hard all over my hand, down her legs, over my wrists, splashing noisily onto the ground. When she was done, she gestured for me to get my cock out, meaning to blow me, but I had other ideas.

"No, later. Wipe yourself off. I want you to walk around with pissy panties."

I watched in amusement as she indelicately tissued up the worst of it, wringing her panties out before putting them back on, and we went back inside. As we did, she whispered in my ear: "Keep that erection. You're gonna need it."

Another time, in a secluded park next to a near-deserted beach. We were on holiday together. We had our hands inside each other's swimsuits, mum was quite worked up but I needed to piss.

"What's up, baby? Something wrong?"

"I'm wondering if I can piss with a hardon."

"Well, today we find out."

It turned out that I could. I pissed all over my mother's chest, a big dark patch all down her front evidence of the contents of my bladder. This time I put my cock in her mouth, she sucked me, and my jizz joined my piss on her chest.

Same place, another day. We're fully clothed, it's a bit chilly this evening. Mum sits on my lap in her cotton dress, we're idly chatting, then my lap is hot and wet. She giggles, pretends to apologise. I walk the ten minutes back to our cabin with piss still dripping from my pants, mum giggling all the way. Only this time, as soon as we get inside, I peel my clothes off and grab her, pulling at her panties. I press her face-down on the bed. She knows what's coming when my finger, full of lube, invades her rectum to be followed by my cock. "This is what happens to slutty mums who piss on their son's laps."

"Mnfff. Mfff. Then..I..should..piss.. Umfh.. on..you more..ow!.. often."

I'm rough, but she's loving it. I can tell because she's holding her ass cheeks apart while I fuck her bum.

Sometimes, just watching is enough for me. And for her, I guess. If we're outside, or in the garden, we often don't bother with toilets. We just piss in front of each other, because it turns us on.

But this is my favourite memory. Mum was cleaning some jars at the sink. I sidled up behind her and began cupping her breasts, pulling her nipples through her braless cotton dress.

"Are you ever gonna leave me in peace?"

"Hell no."

She pressed her butt on my groin and played her game: "I need to finish this, but if you want to fuck mummy, just go ahead baby."

I pulled her dress over her hips, lowered her panties to her knees, and pressed my cock to her pussy.

"What's the matter, Tommy. Don't you want to? Huh? Don't you want mummy's pussy?"

I think she thought I was teasing and this would go on for a while, so I actually caught her by surprise when I pissed all over her cunt, her clit, inside it, up her ass, her buttocks, her thighs.

"Shit baby, you're making a mess."

"I know."

Fair enough. When in Rome..."

My stream faded as hers began, hot, hissing, hard all over my thighs and down my legs. Still it came, a pool of our piss sploshing on the tiles. I pushed my cock inside her, and each time I withdrew I was rewarded with another spurt of hot pee, then I clamped it off by pressing back in. It was hot dirty heaven and in a minute I was ready to cum. I shot, hard inside the womb that made me, grunting as I did.

And that is how my daughter/sister was conceived.
