Truth be told, the first four days of my four weeks of denial were pretty uneventful. I was allowed to worship my beautiful Mistress's pussy on the third day and gave her a very nice orgasm. Afterwards we cuddled until she fell asleep, leaving me to lay awake for some time with a rock hard cock that I wasn't permitted to touch.
I was just starting to wonder whether I should enquire of my Mistress if she was still planning to go ahead with what we'd discussed, but I soon discovered that she was merely toying with me...
On the fifth day, a Friday as it happened, Mistress greeted me at the door with a kiss. We enquired after each other's day and she told me she had booked a local restaurant for 8:00pm. That was just over two and a half hours away. She told me she wanted me to go upstairs, shave and shower quickly and then come to the bedroom.
I was shaved and showered and was through the bedroom door within seven or eight minutes, and when I walked in I was greeted by the most glorious sight. Mistress was laying on the bed, on top of the duvet, completely naked except for her black lacey bra. Her legs were spread wide open and she was fucking herself with her favourite glass dildo.
She told me to kneel on the floor at the foot of the bed and I complied with her instructions immediately. She told me to slowly stroke my hardening cock as I watched her and added that under no circumstances was I to cum or to stop stroking. She said I could slow down if necessary, or loosen my grip, but I must not stop stroking. She paused for a moment and then added, "If you absolutely must stop stroking your cock then you will be punished, but that will be nothing compared to what will happen if you make yourself cum!"
I assured her that I would do as she instructed and curled my fingers around my cock and began a slow, rhythmic wanking motion. Mistress couldn't actually see my cock from where she lay on the bed, but it didn't really matter because as soon as she finished speaking she closed her eyes and concentrated on the glass dildo that was working it's magic inside her pussy. I have always thought watching a woman pleasure herself was one of the most amazing things you could ever see and having been ordered to kneel at the foot of the bed and allowed to watch, made it even hotter.
Mistress pulled the glass dildo out of her pussy and rubbed the deeply ridged toy up and down her lips, groaning as the peaks stimulated her clit. Abruptly she pushed the clear glass cock back inside herself and fucked herself hard with it for a few seconds. Then she pulled it clear once more and held it up so I could see it, her juices glistening on it's super-smooth surface.
"You'd like to taste that wouldn't you slave?"
"Yes Mistress."
"Say please...."
"Please may I taste your beautiful juices from your dildo Mistress?"
She did not answer but tossed the dildo onto the duvet between her feet. I reached out with my left hand to retrieve it, but she stopped me.
"I don't remember giving you permission to do that," she snapped.
"I'm...I'm sorry Mistress."
She watched me suspiciously as her fingers manipulated her clit.
"I hope you're still rubbing that cock, slave."
"Yes Mistress."
"You know better than to disobey me don't you slave?"
"Yes Mistress."
"Have you had to slow down yet?"
"Not yet Mistress."
"Good slave, because you've a way to go yet."
"Thank you Mistress..."
She rubbed her clit for a while as I watched intently, my desperation to taste her juices growing stronger by the second.
"You may suck the dildo slave," she announced finally.
"Thank you Mistress," I said as my hand once more reached to retrieve the glass cock from the duvet, where it still lay between her feet.
"No, don't use your hand...pick it up with your mouth."
"Yes Mistress. Thank you Mistress."
I leaned forward until I could get my lips around the head of the glass dildo and then sucked it into mouth and pulled it back so I could straighten up again. As she had told me not to use my hand, I daren't do anything but hold the toy in my mouth as I continued slowly stroking my cock.
She watched amused, as it became harder and harder for me to hold the dildo in my mouth.
"I hope you're not going to drop my dildo slave?"
I shook my head, knowing that to try and talk would be foolish in the extreme. She smiled.
"That's the best dildo I've ever had slave, but I don't need to tell you do I? I'm sure you remember that time I fucked you with it... you liked that didn't you slave?"
I nodded my agreement, slowing my hand as the memory of that occasion made my cock a little bit harder than it had been previously.
Eventually she allowed me to use my free hand to remove the dildo from my mouth. She told me to spit on it and get it nice and wet, it was fairly obvious where this was leading.
"When you've made it nice and wet I want you to sit on it."
I obediently pushed the dildo back between my legs and eased myself down on the slippery toy. Unlike plastic or rubber, glass is so smooth that even with hardly any lubrication it slips inside and it doesn't drag or hurt at all. Within a half-minute the cock was fully inside me and I knelt back up to continue watching my Mistress pleasure herself.
"Is it fully inside you slave?"
"Yes Mistress."
"Good slave, don't let it fall out, will you..."
"No Mistress."
Hearing this made me thankful for the lack of any artificial lubrication as that would have made that task a lot more difficult.
"I bet your cock is like an iron bar now isn't it slave?"
"Yes Mistress."
"Five days since you came already, but only two for me of course...you did a wonderful job on Wednesday night, as ever... but tonight I fancied a change. So, that's why you're down there and I'm playing with my own pussy for once. Tell me slave... have you ever seen me make myself cum before?"
"No Mistress..."
She knew damn well I hadn't, she just liked asking me these questions for the sake of it.
"No...but you'd like to wouldn't you slave?"
"Yes Mistress," I sighed, somehow sensing this wasn't going to work out quite as I might have hoped..
"Of course you would... keep stroking that cock slave..."
"Yes Mistress."
"Is watching me make myself cum another one of your secret fantasies slave?"
"Yes Mistress," I gulped, quite loudly.
"I see. Well... you've already had one of your fantasies fulfilled this week so I think maybe we should save it for another time. Don't you slave?"
"Whatever pleases you Mistress," I said, trying to hide my disappointment.
She let out a small moan as her fingers worked her clit and she felt herself moving a little closer towards orgasm.
"Hmm, reach under the bed slave, and pull out what you find there."
I reached under the bed and my fingers touched something cold and rubbery. I realised immediately what it was and pulled it out.
"Put it on," she said.
I obediently slid the blindfold over my head and adjusted it so that I couldn't see out of the sides.
"Is it effective slave?"
"Yes Mistress."
"Good."
She fell silent for a while and as my sense of sight was removed I found my hearing becoming slightly more acute. I could hear the sound of my own fingers slowly pumping my cock back and forth and more excitingly I could hear her fingers manipulating her sodden cunt.
As I knelt there slowly pumping my cock, every sound that came from the bed made me want to pump my cock hard until my cum burst from the tip in a glorious stream. But I knew what was expected of me and kept myself under control.
We must have stayed like that for a good ten minutes or so, until I heard a small grunt escape her lips and then the sound of her body convulsing violently on the bed. After she had cum I felt my own orgasm approaching and had to slow my strokes right down. The dildo buried in my ass didn't make it any easier as it's deep ridges rested against my prostate, stimulating it and urging me to stroke faster so that my balls could release their load.
I heard her moving on the bed and thought I could feel her closer to me than before. Then she spoke, and I realised she was right at the foot of the bed, looking down at me stroking my cock.
"Good slave, I am pleased with you."
"Thank you Mistress," I said, hoping that she might tell me to stop sooner rather than later.
Instead she pushed her fingers into my mouth and I licked them clean of her gorgeous juices, slowing my hand even more as I licked between her fingers until every drop was gone.
