He's naked and you are not, so it seems you are off to a good start. Now he needs a challenge. How about challenging him to please you without using his hands? (Hmmm.... I wonder how you will make sure he doesn't cheat.)

How about something like:
"undress yourself while I look at what you've got"
As he nervously continues where she left off, she struts around him
lightly touching his skin but not allowing a response from him. Finally he
is naked. She tells him to bend over the table and ties his hands............

*Both really good suggestions....so here goes nothing*

I look him over, smiling, and slowly stroke my nails over his chest. "Tonight, my word is law. The only words I want to hear out of your mouth are "Yes, Mistress, more Mistress, please Mistress…or peaches if you want things to end. Do you understand?"

His eyes flickered uncertainly. "Maybe."

My nails stroke him again, this time just short of pain. "Try again, baby."

"Yes, Mistress."

I smile, cup him in my palm, run my hands over him just the way he likes. "Good boy." I turn and saunter over to the long coffee table, pulling out two table runners from the storage drawer underneath. "Come here."

With only the slightest of hesitations, he does. I can see both desire and wariness in his eyes, but there's no doubt at all about his erection. He was already fully hard. Gently I stroked over him with the satin runners, rubbing over him until he had to brace himself against the table to hold himself upright. "Do you want more?"

"Yessss, Mistress.” He groaned, arching into my hands, grinding himself against the runners.

“Want to come?” I changed the angle, stroking just a little faster, a little harder.

“Yes, Mistress! Please!”

I removed my hands, taking the runners with me. “Please me, and you might get your wish.” I ran my hands over his shuddering back, listening to his labored breathing as I whispered in his ear, “You haven’t done anything yet to merit that reward. If you want me to let you come, you’ll have to earn it.”

“Yes, Mistress.”

I gestured to the coffee table. “Lie down. I want to see what there is to work with.” He shakily righted himself, then lay down, sprawled across the coffee table; my own personal brawny, handsome, and horny as hell buffet. I tossed one of the runners to him. “Use that to tie one of your wrists to the legs of the table.”

He looked at me, then at the runner. “Yes, Mistress.”

I waited until he finished securely tying the knot, then slowly stroked my way up the length of his body with the other runner. “Well done. Give me your other wrist.”

“Yes, Mistress.” He gave it to me with charming speed, and I tied it to the other leg, then stood back to admire our handiwork. He truly was beautiful to look at; so handsome, so helpless…oh, the things I longed to do to him…I ran my nails down the length of him, to curl possessively around his shaft. “Who does this belong to?”

“You, Mistress!”

“And who do you belong to?”

“Only you, Mistress!”

“Very good,” I purred, taking a swallow of wine as I stepped to the head of the table. “Time for your first challenge.” I swung one the leg over the side so that I straddled his head. “Let’s see if you can get me off with just your mouth.”

“Yes, Mistress.” And with gratifying devotion and skill, he applied himself to the task. God I loved the feel of his lips, his tongue. He licked me, sucked me, tasted me while I rocked languidly on top of him, riding his voracious tongue while he drank me in. Teasingly, I lifted my hips, rising just out of reach of that wonderful mouth. “What do you want?”

“More, Mistress!”

I eased even further away, so that he lay tied beneath me as I stood above his ribcage, I wanted him to see this. I cupped myself with one hand, then slowly eased a finger in and began to pump. “More of this?”

“Yes, Mistress!”

A second finger joined the first, easing in and out while he watched me with glazed eyes. “That’s a start, but you can do better.” I stared down at him, adding a third finger, riding my hand as I drew it in and out. “Beg.”

“More, Mistress! Please, Mistress. Please, please, more!”

I smiled, drawing my fingers slowly out, then held them against his lips. “Lick them. Suck every bit of them clean.”

He drew my fingers in and began sucking enthusiastically. After a few moments, he raised his head.

“All done?”

“Yes, Mistress.”

I lightly sucked on one of my fingers, then dropped my hand to my side. “I can still taste myself. You failed me.” I dismounted, glaring down at him, “I expect absolute obedience, is that clear?”

“Yes, Mistress.”

“Good. Unfortunately, you didn’t obey my wishes. Disobedient little boys should get punished, don’t you agree?”

“Y-Yes, Mistress.” His eyes flickered nervously as I stepped away, returning with the pitcher of ice water in one hand, a single ice cube held between thumb and forefinger in the other.
