"But leave that little dick alone. We don't have time to play with your little toy right now."

Mr Loverman looked slightly crestfallen, but lay obediently with his hands by his sides. He could do with losing a few pounds, I reflected, as I looked at his slightly lardy body. I'd put him on a lettuce diet for the next week, I decided: nothing but lettuce and water for seven days, which ought to lose a good half stone. He didn't seem appreciative when I told him. Damned ingrate.

"Now, as a special treat, I want you to feel my pussy, Mr Loverman. You'll have to close your eyes, because I don't feel like letting you look at me." He did as he was told and I took his hand, guiding it between the flaps of my dressing gown, towards my still hot and throbbing pussy. I took his first two fingers and extended them, then pressed them against my swollen lips.

"Now, get them nice and coated with my juices, Mr Loverman. Get them covered." He complied, rolling his fingers against my inner lips, sliding them inside me, ensuring they were slick with my juice. "Excellent," I cooed patronisingly. "Now rub them against your arse."

He stopped dead and was on the verge of saying something, but bit his tongue. I slapped his head. "Do it!" I roared. Reluctantly, he withdrew his hand and, raising his knees and spreading them, moved it in the direction of his backside. He smeared the fingers against it, transferring my juices to it.

"Better do a good job, Mr Loverman," I chided, "because you're going to need the lubrication." Mr Loverman looked confused. He clearly had some notion of what was going to happen next, but not the full picture. "Want some more?" I asked and he nodded.

I grabbed his hand again and led it to my pussy. Once more he charged his fingers with my fluids and transferred them to his arse.

"There," I said. "Is that it nicely lubricated?"

"Yes," he replied morosely.

"Better check first. Stick a finger in for me, Mr Loverman." I thought he was going to refuse. He made no move, sitting there like a stricken animal. The humiliation of this situation, blindfolded, with his arse on view for his mistress, was clearly getting through to him. Finally, though, he did as I had commanded and probed at his rear end with his index finger. He made little progress.

"For god's sake, Mr Loverman," I scolded, "you're going to have to relax those muscles a bit or your arse is going to get ripped apart." He tried again and eventually the tip of his finger slipped into place. "Wiggle it about a bit," I told him, and he pushed harder, sliding it in as far as his knuckle, before moving it about gingerly inside him. He looked distinctly uncomfortable.

"Well done, little man," I said. "Now keep that finger there." I peeled the blindfold from him again and went to fetch my new toy for the day. Returning with it proudly, I flourished it before him. "Here we are, Mr Loverman," I said. "This is your new companion."

A gratifying wave of shock flitted across his face as he saw the five inch butt plug I brandished in front of him.

"Now, do you want to put it in, or shall I?" I do like to ask him things, make him complicit in his own humiliation.

"You, please," he replied.

"You please, what?" I scolded.

"You please, Miss."

"That's better. Just for that I'm going to make you do it yourself." I handed him the plug and sat cross-legged on the bed inches away from him. I lowered my head so that it was almost next to his backside, affording myself a grandstand view. The bright blue plug was tapered so that it was narrow at the tip, giving easy access, but expanded satisfyingly in the middle. At the base there was a lip to prevent it sliding all the way in: once that happens, only a trip to casualty will get it out again. Which I fully intended to inflict on Mr Loverman at some stage, but not today.

"Well?" I asked.

Reluctantly, he pressed the plug against his anus and pushed ineffectively. He twisted it round and round, before discovering that was unwise before it had embedded itself properly. His grimace of self-induced pain was a joy to behold.

"Relax the muscles," I told him. He pressed again, tears in his eyes, tears of pain and of humiliation, and finally the slim end found a passage and slid a fraction inside him. "Well done," I said, clapping my hands. "Now the rest."

"Is that not enough, Miss?" he said pathetically. He didn't understand.

"Stupid Mr Loverman," I said. "Haven't you worked it out yet?"

"No, Miss."

"That thing is going all the way inside you, and you will keep it there all day, while we're at the conference."

A look of horror crossed his face. I decided to seize the moment and gripped the plug. Pushing hard, I rammed it into place, forcing it up his arse all the way to the rubber lip. He let out an anguished yell as this invader impressed itself on his psyche.

"Okay?" I grinned. I gripped the base of the plug and began to shake it from side to side, pulling it out a fraction and slamming it back in again. Mr Loverman looked panic stricken as I assaulted his rear-end with the plug.

"Never had anything up your arse before, Mr Loverman?"

"No, Miss," he croaked.

"Good, isn't it?" I continued to waggle the plug, pressing it against his prostate. His cock had been hard all morning, but now it was completely solid, the head taut and shining. I pulled the plug back until it was almost completely out of him, then thrust it forward again and Mr Loverman groaned, his body tensing. A jet of come flew out of his cock and landed on his cheek. I repeated the action over and over, and Mr Loverman's spunk leaped out of him, landing on his eye, his mouth and chin, before the last few drops spurted helplessly onto his flaccid stomach. Satisfied, I pressed the plug back into its refuge for the day.

"There you go again, Mr Loverman, making a mess. Get back to your room and get cleaned up, then get dressed. Just hope there's no-one in the corridor. Could be difficult to explain. And make sure that plug stays in place. I'll be checking through the day. Now get out."
