This is story I recently told to a friend about a sadistic scene with a previous partner that sticks out in my mind:

She was being clingy and desperate for attention on a day where I really had to focus on work. I needed some quiet time, and my sadistic brain saw this as an opportunity.

She was already naked, since clothes at home with no guests around were banned for her, but I made her stand, legs spread, arms over her head. I went over to our toy chest and grabbed a butt plug bigger than what she'd recently been training with, nipple clamps, a urinal gag, and a full blackout hood.

When she saw the hood and the gag, I could see the fear in her eyes. She wasn't the biggest fan of the dark. That look of fear instantly got me hard.

I told her to put the plug in for me, and the only lube she could use was her own spit. I watched her suck and drool on it, telling her how pathetic she looked before she tried to work it into her ass for me. It hurt, that was the intention, but eventually she got it in.

I put the clamps on her nipples. This was fairly mild, but I knew I was putting her away for hours so I wanted to take it somewhat easy on her.

Without saying a word, I grabbed her by the throat and dragged her to the bathroom. I shoved her down on to her knees, next to the toilet and looked her in the eyes. "So you want attention, cunt? You got it. You can be my toilet for the day." She started pleading no, and that made it all the hotter. I knew she had such a love hate relationship with piss play. "Shut the fuck up, cunt. This is what you wanted, isn't it? To be useful? To serve me? Then look me in the eyes and say 'I will be a good toilet, Sir.' "

She started crying, but hesitated. I grabbed the chain between the clamps and I yanked hard. She screamed and then, through sobs, told me what a good toilet she'd be for me. "That's a good whore."

I then affixed the hood, blacking out all light for her but leaving her mouth exposed. Next came the gag. Then, without saying a word, I turned off the lights, shut the door, and left her on the floor of the bathroom.

Over the course of the day I made sure to stay very hydrated. When I had to piss, I'd go into the bathroom, turn on the lights, say nothing and piss into her gag. I'd laugh to myself as she sputtered and struggled to swallow, and then wipe my cock off on a part of her before leaving again.

I did this a couple of times over the next few hours while I got my work done in peace. Finally, when I was done, I went back into the bathroom, took her gag off, and saying nothing I fucked her throat until I came.

She was whimpering, but she still thanked me for my cum like a good slut. I then took off her hood, helped her up, removed the clamps and took her over to the bed. I relished a bit more of her pain as I pulled the unlubed plug from her ass and then made her lick it clean, before I rewarded her with a nice hard fuck for behaving so well.

After that it was all after care and vanilla fun.
