Friday afternoon, the day in which, hopefully, I would have some release. I connected the device to my laptop, a square of plastic with slots for several connectors that looked like a hard disk, and the user menu popped up. There was a 50% chance that the program would let me reconfigure randomly the parameters once a week. The “reload” button was enabled. I hesitated a little. The last configuration wasn't particularly hard and the new one could be much worse. Carol, my best friend, and the person who had helped me downloading and configurating the program, and buying the device, wanted me to click the button. She had been always there. She was completely familiar with my fetishes. Because I wouldn't be able to do all that without her I used to adress her as “Mistress” when we were alone.

The “reload” wasn't a requisite. Carol just thought that routine would be more boring. Besides, in general she used to give good advise. She was coming later to pick me up and would take a look at the parameters. I clicked the button.

The new configuration said: intercourse-allowed; requisites-2f+1m; password; total-0; release-Wednesday 21.00; intensity-2/5, 20min. Meaninng that the wednesday at that hour I had to connect the device so I could enjoy 20 minutes of the egg vibrator, that I carried inside me on a regular basis, at less than half its intensity. That function didn't specify a number of orgams. It didn't matter, I doubted that at half intensity I would reach more than one, anyways. Probably I would reach none. The zero on the “total” parameter meant that the chastity belt would remain there. Otherwise I would be allowed to masturbate as I saw fit, including clitoral stimulation, to earn as many osgarms as the number indicated.

The requisites were the most tricky part. In order to get my release, Carol, who was the designer administrator of the program, while I was just an user, and who had configured the parameters, had to type her password before the appointed hour. I didn't know how did the program work exactly, and what were the chances for any of the parameters. Carol had decided all that. “2f+1m” meant that I had to give a woman two orgasms, and one more to a man. In other words, two for Carol and one more for her husband Simon, my usual volunteers. If I did so, she would type the password and I would have my release. For some reason it was rare a week in which I didn't need to pleasure her at least once. She was clever, indeed. One week I gave her six orgasms along three days, just to get ten seconds of max power. Thankfully, after that she changed the parameters to give me a minute as a minimum.

With Simon was easy. Carol decided whether if it would be hand or mouth and I did it. He was perfectly fine with that system, proven that I just needed a penis, not his penis in particular. She used to put more conditions for herself. We had been friends since childhood and she knew my limits perfectly. She never asked for anything hurtful, humilliating, dangerous or too unpleasant. Instead she used that as a leverage for many things. She put me on a diet, she forced me to change my clothing style, cut my hair so my neck was visible, and many other things. She made me keep my apartment perfectly clean, while also helping her cleaning hers. More than a friend she was like a very controlling big sister. I had to admit, though, that many of those requests were beneficial for me. She was a good friend and I owed her a lot.

With that settled I disconnected the device and started to undress to take a shower. I didn't particularly like my clothes. I dressed as if I were ashamed of my body. Always covering as much skin as possible. High collars, long sleeves, long skirts, etc. With them I was sending a message to any possible future lover. That I was not looking for lovers. One of the reasons was under my skirt. I was forced to wear them loose, pleated or flared, knee length, at least. Never hip hugging, because that would reveal the chastity belt.

The belt was mostly black carbon fiber. Strong, light, very thin and quite expensive. The waist band hugged my waist tightly. A plastic cable at each side of my mound led to the crotch plate, an elongated triangle that hung less than two inches below the waist band and ended on the perineum. A bunch of small holes just below my crotch let the body fluids pass. From there two thick bands of plastic went up to the back of the waist band, towards one side each. Some kind of foamy waterproof material lined the inside of the waist band and crotch plate. It felt a bit cold for being honest. A single steel padlock in front of my waist, small but sturdy kept me locked. There were only two keys, one in Carol's keyring, and the other one in a drawer somewhere in her apartment. From each side of the belt another cable went down to two more plastic bands around my thighs, no more than two inches below my crotch. Whenever I was wearing a skirt, I had to fit a last cable between the D shaped rings embedded on the thigh bands, around seven or eight inches ended in two small clasps. I knew that the swing of my ass posed a good view. The strict diet and the mandatory jogging mornings kept me in a good shape. Sadly for those interested, only two persons had touched my buttocks in years, Carol and me, and I needed no more for the moment.

At last I removed the black velvet choker around my neck. Just an inch wide, it closed at my back with two small clip buttons. In front, with red thread was sewn “C&M” inside a heart. Carol and Monique. Difficult to see, perhaps, but it was there. I tried to keep it always visible, even wearing tall collar shirts or sweaters. The last years I had been wearing a golden ring in my finger. Those two elements created a pretense.

No man had touched my pussy ever. Only my friend had. The first time was during her nineteeth birthday, after a few beers, because she wanted to experience some things. Many times after that with and without toys. There was never romance involved, just two friends playing. She was fully straight. I was more nonsexual, so to speak. Maybe in the future a man would open my flower. Not yet, though.

After the shower I put on a robe. I heard sounds coming from the living room, the TV was on. It musted be Carol, she had the keys to my apartment for the same reason that I had hers. I quickly refitted the choker, the symbolism was important.

-Hello, Mistress.- I said in a cheerfull tone. I gave her a light kiss on the lips as we used to do, and sat on the couch next to her.

-Hello, dear. Wednesday, then?- I had texted her the information, earlier. I nodded.- Good, so today you are coming home and eat dinner. We will play Wii, I will put Eric to sleep, and you'll take care of Simon. Hands only today.- Eric was their little boy.

-And what about your part?

-Hey, not so fast. You still have to wash your dishes, and there is a lot of dust is this room.- She tickled me under the armpits.

-Oh, come on.- I grabbed her hands to make her stop.- I've just come from work and took a shower.

-Ok, clearly you have a big interest in pleasuring me..., for your own selfish reasons, I must say.- I laughed sardonically.- I'll let you do the first one today. The second would be the same Wednesday, you are going to be mine the whole afternoon, and better if you make me happy for your own sake.

-Yes, my awesome and lovely Mistress. So,what? Dildo? Hitachi?

-For being honest I was thinking... What about..., your tongue?- That was new. I needed a moment to process the idea.

-What? But... I've never... I don't know how...

-Please, it's me. It doesn't matter if you are not an expert. You just try, please...- Her childish pout made me laugh on the inside.- Please...- I still hesitated a bit more.

-Ok.- I nodded and knelt on the floor. I grabbed both the hem of her jeans and her panties and was about to remove them when she stopped me by holding my hands.

-Of course you know that I can just type the password and we can skip this part.

-No, no, Mistress. The game is the game. I accepted the rules and I'm fine with them. You decide over your pleasure. Errr... I'm going to need a few tips. You know. Faster, slower, up, down... All that.- She looked at me with a quizzical expression. Wasting no more words she slidded her hand over my head towards my nape and, closing her eyes and getting comfortable on the couch she brought me closer to her crotch.

I had watched enough movies and read enough magazines to know the basics. I kissed her softly on the labia several times and then on the clit once, she confirmed that I was doing it right with a soft moan. After a few kisses more I proceeded to short lappings. She brought my head closer which I guessed meant that she wanted more intimacy, so I stuck my tongue inside her and lapped on her g-spot. She rested her legs over my shoulders and pressed on the sides of my head with her thighs. I was doing it great. After a few minutes I started the main function. I rubbed on her g-spot with two fingers while used my mouth and tongue to suck and lap on her clit. No more than twenty seconds later she moaned loudly and immediately after her legs fell to my sides. It was over.

-Wow!- She said after a few moments of silence. She voice sounded exhausted.- You know that I'm having more sex with you than with my husband. Shit, even Simon is having more sex with you than me some weeks.

-That's why people get married, no? Because they are tired of good sex.- She didn't find my joke funny at all.

That same night, as Carol said, we played Wii. Eric fell asleep and Carol took him to his bedroom leaving me alone with Simon.

-We have to do something, yes?- He said coyly. After all this years he still found awkward my games with her wife.

-Yes, we do.- I gave him a warm smile.- Here?- I didn't wait for an answer. I unzipped his trousers and took his penis with one hand. With the other I grabbed a napkin and covered the area in preparation for the shot. I had had that thing in my mouth many times, shyness was utterly unnecesary.

-You aren't going to..., find a boyfriend and... I mean... I'm not comlaining but... You know... Build your own family.- He closed his eyes and gulped. I was increasing slowly the pace as I knew he liked.

-Not for the moment, no. I'm more than fine. Now, dude, shut up and focus on the task at hand.
