She's insatiable

'Summer got up mid-morning the next day - at least I had a few hours to do some work, cos by this point I could see that my life was gonna become pretty difficult. I either gave into Summer's demands, and kept fucking her, hoping that she'd never tell on me, or that I didn't get found out, or tell her mum, and potentially lose everything. She sauntered into the office wearing her skimpy school uniform outfit: pleated tartan skirt, so short you could see her ass cheeks, no knickers; white shirt, tied up under her boobs, midriff on display, and hair tied back in pigtails. She knew what she was doing. She said - time for my lesson Sir.'

'What did you say or do?'

'I said - I've got work to do, what do you want me to do? You're the one blackmailing me, remember? - and she replied - I want you to do whatever you want to me, the same as you did yesterday but harder, rougher, convince me that you don't give a shit about me, that's what I want today, use me, **** me.'

'And did you?'

'She was blackmailing me, of course I did, and before you ask, yes I enjoyed it, I wanted to hurt her, each time I fucked her I wanted her not to enjoy it, but each time she got off on it even more, it was a lose lose situation.'

'Describe what you did please - we have her report on this encounter, and we need to compare it to yours.'

'Well, first of all I fucked her mouth, and I'm talking face-fucking. I held her head and went at her throat till she was gagging, slobbering all over the place. Then I dragged her over to the sofa and placed her on her knees and plunged into her pussy balls deep. She was so wet, and I couldn't get over how she was getting off on whatever I was doing. So I decided to teach her about delayed gratification. I slowed right down, and just fucked the opening of her pussy gently with the tip of my cock. She started pushing back into me, trying to get more cock inside her, but I pushed back on her ass so she couldn't, and slipped my thumb up her butt for good measure. This went on for about five minutes, and she was telling me she was about to cum. That's when I said - time to learn about the fact that good things come to those who wait young lady - and I withdrew, and tied her hands behind her back with the belt from my trousers. Then I went to her room and found a couple of dildos that had suckers on the end. I put one on the floor and one on the wall. I told her that I needed to work for an hour and her task was to use the dildos in her ass, until I was ready to fuck her again.'

'And did she do that? You just left this 18 year old tied up, and instructed her to fuck herself in the ass?'

'Yep - I was trying to annoy her. I got on with work and she started fucking the dildo on the wall with her ass, following my instructions. Every so often she would stop, I mean it must've been quite difficult with her hands behind her back to balance. I would then stop what I was doing momentarily, give her a spanking and tell her to carry on. she found the one on the floor more difficult, but did manage to lower herself onto it and fuck it, even getting on her knees, keeping it in side her ass, and twisting around so I could see her fucking herself.'

'What happened after the hour?'

'I got her to walk over to me, got my cock out in my office chair and sat her gaping ass down on me. I got her to fuck me for a while, then I decided to finish her off. I decided I was done with her pussy, no more pleasure for her. I carried her over to the sofa, threw her on her back, and then fucked her little ass mercilessly. I hammered it, and it was nicely open after her dildo fucking, really wide. I basically treated it like a pussy. But I just couldn't seem to inconvenience her - she was shouting at me to fuck her harder all the time, and I was balls deep in her ass. I flipped her over and put a cushion over her head just to shut her up, and then accelerated. Despite no pussy action, and being unable to frig her clit, her ass was tightening around my cock, she was cumming no matter how horrible I was to her. I came deep in her ass.'

'what happened next?'

'I got her on her knees and made sure she cleaned my cock with her mouth, then untied her. She then used her fingers, not on her clit, but to search for cum inside her ass and then lick it off. She is depraved, there was nothing I could do. I felt profoundly depressed. She just said - nice work Sir, same time tomorrow?'

'well thank you for that description - her version of events differs in that she alleges it was all against her will. And what happened the next day?'
