A re-post of 7 letters one of my stories, looks like I never finished it maybe I will now.

Seven letters.
I've been watching you from the shadows for hours now, even though you still think your alone, still think I abandoned you. Sure there were a couple of times I was sure you were going to catch me following you but I guess I got lucky.
I still remember the look on your face when you woke up this morning. Shocked and dismayed at what I had done, OK so maybe it was a little underhanded to slip you a sleeping pill before we went to bed, but I had to make sure you didn't wake up when I put it on.
"Master?...what?...why?...what is this Master?" was all you could manage to stammer out when you saw the chastity belt, felt the buzzing eggs inside you.
"It's your project for the day little one. You see little one I thought because you can't seem to stop cumming without asking permission you could come all day today."
"Please Master take it off I'm sorry don't....don't make me...don't make me spend the day like this." I couldn't help but chuckle as you pleaded with me. No this time I was going to make sure you remembered to ask permission.
"I'm sorry little one you have to wear it, I couldn't take it off if I wanted, I don't have the keys."
I wish I had a camera then, the look on your face was too much, horror, terror, anger and pleasure all mixed with utter shock and bewilderment, it was all I could do to keep from laughing myself silly as you screamed.
"YOU WHAT!"
"Careful, remember who your talking to." I replied calmly, or as calmly as I could while trying to hold back my laughter.
"I'm so sorry Master, I didn't mean to, its just, I thought you said you didn't have the keys for my belt and I..."
"I don't. You see I have to work today so I can't be sitting here waiting for you to learn your lesson and unlock you and I can't take you to work so I found another solution, you can unlock yourself." I couldn't help grinning as I told you this, I had booked today off as a personal day, just for this.
"I don't understand if you don't have the keys, how do I unlock myself?" I could tell you were getting worried especially because you had finally noticed that the closure of the belt was not closed with just a lock but a clamp which was in turn locked with 6 individual locks, meaning you would need keys for all 6 locks to open it.
"Well that's where this comes in." I told you holding up a small blue envelope marked with a gold and blue "1" on a small white panel on the front. "You see little one, this is the first of seven like it. Each envelope holds a riddle and a key. Except this one which just has a riddle and the last one which just has a key. If you solve all six riddles you can take the belt off, if not, well...I guess we'll have to start all over again tomorrow." I grinned again at the last comment, I knew after a day of constant buzzing in you ass and pussy you would hardly be able to walk let alone try again but it was fun to watch you squirm as you realized there was only one way out.
"Please Master just take it off I promise I'll be good, please please please".Now I did laugh at you as you crawled out of bed and across the room to me begging me to release you.
"Suck me well enough and I might consider it." That was all the provocation you needed, to practically rip my pants open and begin devouring my cock and devour it you did! Your tongue dancing around the shaft twirling at the head, again and again pushing it all the way back into your throat and clenching on the head as you forced yourself to try and swallow for just such an effect. All till I couldn't hold back any longer and shot my load in your mouth, which too you greedily devoured. Truth be told I almost did release you then just so I could fuck your tight little pussy, but no, I have more self control than that.
"So will you take it of now Master?" you asked coyly after swallowing.
"Nope, sorry little one like I said I don't have the keys, and I have to get to work, I should be back by five that's about nine hours from now and I expect you home by then keys or no keys, don't worry though the batteries should last at least 12 or 13 hours yet so you'll have plenty of orgasms before you get home. Actually you better get dressed too or you'll miss your Bus." I said as I did my pants back up and walk toward the bedroom door.
"Bus? Wait why do I have to take a Bus Master?"
"Oh shoot I think I ruined the first riddle oh well that should get you started"
"Wait Master PLEASE why do I need to take a Bus?"
"Because I'll have the car and you need to find the next 6 envelopes. You didn't think I would hide them here, did you? That would be far to easy. No I hid them all over the city, and like I said you may want to hurry you have just enough time to get dresses and catch the seven o'clock bus. If you miss it you'll have to take the next one and by the time you get to where the other envelopes are someone else may have already found them."
The look of horror on your face then was truly amazing I didn't think anyone could ever look so shocked and horrified. Personally I couldn't tell which had shocked you more that I had hid them so you had to go out in public or the thought one of the keys might go missing. Honestly I still can't fathom how you could even think I wouldn't have a spare set of keys. Though admittedly I had hid them at work so I could say I didn't have the keys without lieing.
"But...But...that means...you couldn't...you wouldn't...oh please Master don't make me do this." Was all you had said, at least that's what I think you said I could barely hear you you were so quiet.
"Sorry little one and like I said you need to hurry its a quarter to seven, I can drop you off at the bus stop but after that your on your own." It took you a minute to register before you started moving. I headed out to the car to wait, smiling to myself as I did. being a ten minute drive to the bus stop you had a little less than five minutes to get dressed and get to the car, just enough time for you to get out of bed, and get some clothes on, no time to shower the sweat from the night off or brush the taste of cum out, honestly I wasn't sure if you had time to put on underwear.
I had just started the car and lit a smoke when you emerged from the house pulling mist of your hair into a pony tail leaving only the dark curled bangs in front. Since moving in with me as my full time slave you had been working on building a new wardrobe to suit my liking, as such your selection of clothes had been limited at best, but what you had chosen was obviously been simply whatever was readily available. You were wearing black knee-high hooker boots with a four inch heel, a short pleated schoolgirls, what looked to be a tank top in bright pink and your short black leather jacket, neither of which did much to hid your breasts or their erect nipples. Apparently you didn't have time for underwear after all.
"Are you sure you want to wear that little one? I could wait? There's other buses, of course not for another half hour." I grinned, rather than respond you simply glared at me sinking lower in you seat with your arms folded across your chest, like some child not getting what they wanted. "Oh come on now I'll tell you what I'll help you with the first riddle, you brought it didn't you?"
"Yes Master" was your reply as you pulled the blue envelope out and tore it open. Inside was a simple white card with a riddle written on it:

Up and down,
round and round
we count and count
but never count down.

We sing and ring
yet don't have wings
but faces mount
for us to count.

"I don't get it. Counting? Sings but no wings? Faces mount? It makes no sense Master Please can't you just take me to the keys? Please Master?" You begged again I could tell from the way you were rubbing your legs together constantly and the sheen on your thighs that the buzzing eggs were having a serious effect, I wonder if you came when you were getting dressed?
"No little one but its easy think about it, what has a face, rings, and counts?" I asked, still enjoying the little game.
"I don't know that's what I'm saying if I could just turn off the vibes, maybe just for a little while just a couple of minutes...wait that's it its a clock Master?!"
"That's right, see you can do this!"
"But that doesn't help me what clock there's clocks everywhere." I put an arm around you and pulled you towards me.
"Its OK, just read it again little one, maybe there's something you missed, you'll get it I'm sure." I had told you.
