For the past couple of weeks, Sir has been doing one of these 'Social Media challenges' along with some of the guys he works with. Its called "no nut november" and its to raise awareness of some sort of cancer apparently.

I was a bit put out that he decided to do it without talking with me first, and told him that it was silly, and that the people he works with probably weren't even really following through, but he stuck to his guns, so we're not having sex at all this month. Let's just say I made my feelings clear about that!

The day after Sir announced his intentions, he came to me with an idea to help me deal with my frustrations. He sent me a link to a 'Spin The Wheel' app, with a wheel he'd created especially for me. It was divided into 10 sections - 8 of them labelled as "Edge", 1 labelled "No touch" and the last "Orgasm".

The rules as he explained them were simple. Whenever I got in the mood, I could spin the wheel as many times as I liked. If I rolled "Edge", I had to bring myself to the brink of orgasm before I could spin again. If I got Orgasm, then I had 10 minutes to make myself cum. However, if I spun "No touch", that was game over. I wouldn't be allowed to do anything with myself until the following morning, when I'd be allowed to use the app again.

Of course, I pressed the button to spin the wheel as soon as Sir finished explaining. I got edge.

"Well? Off you go then" he said.

I protested that I was just testing it out, and that I didn't really have time before leaving for work, but Sir wasn't letting me get away with that.

"You pressed the button, now you have to do what it says!" He was smiling as he said it, but I knew he was deadly serious.

I was still pretty angry, so instead of going into the bedroom and getting comfortable, I lifted the front of my skirt and put my hand inside my panties right there standing in the kitchen and with my eyes locked to his.

I wasn't actually intending to pleasure myself for him, but having Sir stood right in front of me calmly commanding my obedience with his eyes, my resolve wavered. Instead of holding my hand there inside my panties, I let my fingertips drift lightly over my clit. I had to admit it felt good.

My fingers started moving faster and pressing harder as I felt my arousal rising. A finger dropped down to my entrance, surprising myself with how wet I was. I moved back to my clit, using my juices as lubrication as I rubbed faster and faster, using the up and down motion I enjoy so much.

I could feel the pressure building in my stomach as I neared orgasm. It would be so easy to keep going and let it wash over me. I was sorely tempted. It would feel so good and be a fitting payback for Sir depriving me of his cock. Just a few more seconds and there would be no turning back.

I don't know if it was the rising pitch of my gasps or the look on my face. Maybe it was just because he knows me so well, but something told Sir what I was thinking.

"You're a good girl, Emily" he said. On the surface, it may have sounded like praise, but I knew it was a warning. Yes, I was a good girl, but if I kept going I'd be a bad girl. And bad girls get punished.

Even so, I was tempted. The joy of the orgasm and the chance to defy him might even be worth the price of being spanked by Sir.

I managed to stop myself before I got too carried away, pulled my wet fingers free and held them to Sir's lips. He wasted no time in licking and sucking them clean. As I kissed him goodbye, I could still faintly taste myself on his lips.

The day at work dragged on. I kept thinking about the wheel app. I even toyed with the idea of giving it a spin during my lunch break but I couldn't even decide what result I wanted. Another edge would be good, but ultimately unsatisfying, and if I did manage to hit the jackpot, I wanted to savour the orgasm, not rush through it in a toilet cubicle, trying not to be too loud. I waited.

When I got home that evening, I had my phone out before I even took off my coat and shoes. Edge again. This time I made myself comfortable on the bed and picked out a silver bullet vibrator.

I knew it wouldn't take long, but as soon as the toy touched my clit, I could feel my orgasm waiting to pounce. I turned down the power as much as I could and teased myself, running the tip of the bullet lightly over my wet pussy lips, circling around my clit, coming as close as I could without making contact.

Even that small amount of stimulation was too much. I caught myself thinking "It wouldn't be that bad, he wouldn't know". I wanted to give in to that voice so badly, but I'd accepted the game, so I had to play by the rules.

That didn't mean I couldn't bend them a little though. Sir had said I could spin as many times as I liked after all. While still lightly teasing myself, I reached for my phone and presses the button again.

Another edge. Since I was already there, I wasn't sure what that meant I should do. It was hard to think clearly. My pussy kept demanding my attention, telling me how much she wanted to cum, how much I wanted to let her.

I decided that I would count to 50 while keeping myself on the brink of orgasm and then I could spin again. I thought that would be easy enough, but each time the bullet grazed a little too close to my clit I felt an almost painful burst of pleasure and lost track.

After reaching 20 for what must have been the third time, I spun the app again. I was almost scared to look at the screen to see the result. Could I pretend I got the answer I wanted? Of course I couldn't really convince myself to do that, so I took a quick peek.

It was another edge. I screamed in frustration and threw the bullet across the room. I didn't think I could take the torture of teasing myself like that again, and not having the blissful release at the end.

I took a few deep breaths to calm myself. My orgasm was still there. Still waiting for me to slip up and push too far. I pinched my nipples hard, thinking the pain might help to alleviate my suffering, but even that only made my pussy clench with longing. It felt so good in fact that I started to wonder. Was my body so needy that I could cum without touching my pussy at all?

I rolled my nipples between thumb and forefinger, imagining Sir touching me just like that. His lips on me, sucking, biting, licking. The fantasy felt so real, it was almost like I could feel his fingers inside me, thrusting deep into my pussy, driving me closer and closer...

With a gasp I opened my eyes and pulled my hands away, laying spread-eagled, naked and covered in sweat on my bed as I struggled to control myself.

My eyes fell back to my phone and I shivered. I didn't dare press that button again. At least not until after I'd had a long cold shower and got a grip on myself. I decided in that moment that I needed to make a rule of my own. In future I was only allowed two spins in a row, whatever the results may be.

These past two weeks have been tough. I've had more edges than I care to count, and one full day of not touching myself at all, but I've also had two delicious orgasms and I'm no longer upset about Sir and his stupid challenge. Well, at least not as upset.
