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.
