My name is Dita
I'll be your mistress tonight
I'd like to put you in a trance

"Happy Birthday, Mr. Grissom."

He expected the greeting from Lady Heather, the way she pressed her body to his and touched her lips to both his cheeks. The lips were too intimate, would mean there might be more in store for them. And that was simply not in the cards.

Well on this particular evening anyway.

Because her Ladyship had something special in store for Gil's birthday.

Her arm slipped through his and she led him toward the staircase. She was chattering away about this and that, but Gil was too tired to hear quite what she said. He vaguely registered her words over the music playing throughout the main playrooms of the Dominion.

If I take you from behind
Push myself into your mind
When you least expect it
Will you try and reject it

"Lady Heather, I would prefer to spend my evening at home. It's been a long day."

"All the more reason you should be here, Mr. Grissom. I've arranged a special birthday surprise for you."

They stopped outside one of the wooden doors that lined the hallway. Gil knew what was behind that door. It was one of the private rooms. One of the ones reserved only for the highest paying customers. The CSI supervisor tilted his head at the woman, confused.

"I don't understand."

A well-manicured hand slid over the solid wood of the door before she looked his way. "You are one of the few people I can call friend, Mr. Grissom. And beyond that, you're a well paying customer. I reward my frequent visitors." That hand lifted to touch his cheek. "It's your choice if you wish to go in there or not, but aren't you a little curious as to what you'll find."

It was true. She could read him too well. "Very well. Thank you, Lady Heather." He took her hand and kissed it softly before turning to the door. The mistress pushed the door open for him and he took the first step within the room.

The darkness made it difficult to see and the light from the cracked door did nothing to make the room more visible to his eyes. There was movement, the rattle of chains and a muffled groan. His attention shifted and he could make out a faint outline of someone kneeling on the bed, arms above his head and held by chains that came from the ceiling. The body looked familiar. The shape, the muscles...

"Nicky..." Gil breathed.

"Do you approve?" Heather was behind him now, whispering, purring in his ear.

"What is he doing here?" The CSI was torn. He wanted to turn to Heather and demand she release Nick from the chains. The Texan captivated the other part of him, the way he was hanging there, the lines of his body stretched. The chains made more noise as Nick moved again. It seemed as if he were trying to hear who was talking. Gil kept his voice quiet, not wanting the Texan to hear him just yet.

"He came to me and told me his fantasy. Since it seems to fit with one of your own, I made a few arrangements."

His fantasy, Nick Stokes, was right there. Gil's eyes had adjusted enough to the light that he could see every toned line of the man's body. His own body reacted to the sight and Gil let a low moan escape his lips.

"I take it you're not going to let this opportunity pass you by?"

He finally turned to face the redheaded woman and smile found it's way to his lips. He reached for her hand, lifted it so he could press a kiss to her palm. "Thank you, Heather. This is the perfect birthday present."

"I knew it was." Heather pulled her hand away and touched it to Gil's cheek. "Enjoy." With a smirk the woman turned and breezed out of the room, closing the door behind her.

The room sank into darkness and it was going to take a few more moments for his eyes to adjust again. In the meantime, Gil stripped himself of his work clothes till nothing remained. The entire time his eyes were riveted to the outline in the dark.

When he could finally see, he stepped closer and realized there was a length of silk wrapped around Nick's jaw and mouth. Gil reached up, pulling the silk his mouth.

"Lady Heather? I think I changed my mind," were the first panic-laced words out of the younger man's mouth.

Gil stroked work-callused fingers along Nick's cheek, smiling when the Texan's body went rigid. "It's too late to change your mind, Nicky."

If I'm in charge and I treat you like a child
Will you let yourself go wild

"Gris?" Nick started to fight against the bonds that had his arms over his head. "Gris, man, I can explain. What I told Lady Heather - "

"Your fantasy."

"That was supposed to be - "

"Are you afraid, Nicky?" Gil interrupted him. There was a table lined with candles on the one wall. Grissom moved that way and lit the candles one by one. When he was finished, he turned to watch the light flicker off tanned skin and toned muscles. "Are you going to answer me?"

Give it up, do as I say
Give it up and let me have my way

"A little yeah," Nick told him with a short laugh. "I didn't think she would call you."

Gil reached out to stroke his hand up Nick's back, smiling when he got a shiver out of him. He leaned his lips close to Nick's ear, breath whispering over the surface. "Do you want me to let you go? If you want to walk out the door now, you're free."

It was an offer he made solely for Nick's sake. He was giving the man a choice. He could leave now and forget this. Or...see what the older man could do for him.

He seemed to consider it for only a few minutes. Probably working everything through his head. "No fucking way am I going to give this up."

Teeth snagged Nick's ear and he sucked on it before pulling away. "Good." He rubbed his hand over the curve of one ass cheek. Soothing before...

the crack resounded through the room.

Nick let loose a muffled sound of surprise. Surprise that Gil had smacked him. Surprise that sent a shiver of not only pain, but excitement through his body.

Once you put your hand in the flame
You can never be the same
There's a certain satisfaction
In a little bit of pain

Gil reached up and finally untied the silk from Nick's eyes. "Have you had sex with men before, Nicky?"

Nick could finally see the room. He could finally take in his surroundings and reflect on what he was doing and holy FUCK Gil Grissom was naked in front of him. If anyone made fun of Gil for being past middle age, he was going to deck them one.

"Answer me, Nicky."

There was another strike to his ass and Nick muffled a curse. "Yes, sir. Why do you think I left Texas? Good God fearin' boys don't have sex with other good god fearin' boys. I left before mama could find out and disown me."

Gil nuzzled the back of Nick's neck, hearing the pain in his voice. The fear that his parents would disown him if they found out he was gay. Gil didn't know how it felt to live with that kind of fear. His own mother had told him long ago that she respected whatever choices he had made.

And she often pressed him to bring his lovers to meet her.

But this wasn't the time to think of mothers. It was time to forget everything.

It was time for a new lesson.

If you're afraid, well rise above
I only hurt the ones I love

"Do you trust me, Nicky?"

The chained CSI shifted on the bed, trying to turn and look at his boss. "What do you mean? Course I trust you."

One hand slid up Nick's side, along the expanse of his chest. Gil tipped Nick's chin a little more and teased the first kiss out of him. It was soft, light and if they hadn't been in this situation, it might have been innocent. In no time the kiss became demanding. Nick moaned against his lips and Gil felt the shiver run up his spine.

Abruptly he broke the kiss and slid off the bed. On the candle lined table there were two little glass dishes. One filled with condoms, the other with single use packs of lube. Gil plucked one from each bowl and returned to his position on the bed. One hand reached up and flicked the release on the restraints.

Nick lowered his arms and moved them around to get the circulation running properly again. He had to admit he was a little disappointed that he wasn't going to be staying in that position. But ah well. There was always next time, right.

Before Nick could say anything, he was pinned to the bed, his wrists held captive by Gil's hands. He whimpered, arching up to get any bit of friction he could. From the moment he'd seen Gil naked, he'd been painfully hard.

"When I let you go, I want you on your knees. Understand?"

Nick nodded, wondering (though not for the first time) what the hell he was doing. He couldn't possibly be in this situation. Not with Grissom of all people.

His wrists were released and he scrambled to do what Gil had asked him to do. He rolled over and pushed himself up onto his knees. He closed his eyes, tried to keep his breath steady, but it was too difficult. Next to impossible he would say.

From his position behind Nicky, Gil looked him over. His breath caught at the sight. Nick's ass up in the air. Ready and waiting for him. Nick had always been a temptation, a perfect body, a quick mind. The Texan had seemed like the perfect package. And now, here he was.

Gil ripped the packet of lube open and a small drop was applied to his fingers. Carefully he smoothed the lube over the pucker of skin before he slid two fingers inside. Nick squirmed against his fingers, taking them deeper. Gil leaned over, touching his lips to Nick's spine.

"You really want this, don't you?"

Nicky moaned and moved his ass more. "Fuck. Yes, Griss." The hand came down on his ass again, making Nick whimper.

"What do you say, Nicky?"

What was he supposed to say? And then the younger CSI remembered the setting, where they were. "Please, Gil. Please," he begged. Ain't too proud to beg, Nick thought with a laugh in his head.

The fingers in his ass twisted and scissored, stretched him. From what he already saw, Gil Grissom wasn't a small man and Nick knew he might be hurting for the next few days. But fuck, it was all going to be worth it.

Before he knew it, those fingers were gone and he made another whimper, trying to get that sensation back. But in another moment, there was a new sensation. The head of Gil's cock pushing into him. Nicky grit his teeth, forced his body to relax enough to allow the other man entrance. Fingers twisted in the sheets and he wanted to touch, but Gil hadn't told him he could touch.

The thought was absurd. You're supposed to touch your partner during sex, but something in Nick's mind had been triggered from the start. This was what they meant when they talked about submission. Giving yourself over completely to one person and allowing them to have control.

With Grissom, Nick was sure it wasn't such a bad deal.

Another smack came to his ass and he realized he'd been thinking too much. He really needed to stop doing that when he had his boss' cock buried in his ass.

Gil stroked the tender flesh of Nick's ass, marveling at how red it was starting to become. He bent over him, teeth gliding along a shoulder. He shifted the angle of his body and when Nick screamed, he knew he'd hit the jackpot, so to speak. He pounded over and over, pulling more sounds from Nick's throat. The younger man was pushing back against him, trying to take him deeper. Muscles clamped around him and Gil was fairly sure he was going to lose his mind -and control- in the next few minutes. There was no way he could hold on with the way Nicky was moving under him.

He reached under Nick, callused, work-worn fingers wrapping around him. The smaller man bucked against him and moaned deeply. Gil's groans joined in the chorus as he pounded harder, stroking Nicky as he did. Before long, the Texan cried out and spilled into his hand. Gil wasn't far behind. A few more pushes and he poured everything into Nick.

For a few long moments, the two remained still, unmoving as heart rates worked to return to normal. Finally, Gil slid himself from Nick's body and fell to the bed, pulling him against him. He pressed kisses to his neck and shoulders, beard tickling over his skin.

Nick laughed softly and relaxed in the circle of Gil's (his lover's?) arms, eyes sliding shut. "Damn. That was..." He really couldn't find the right words to describe it. "All I know is, I think I wanna be a greedy bastard and demand we do that more often."

"I think I can oblige you on that." Gil looked down at Nick, smiling when he saw he had fallen fast asleep. Gris wasn't too far behind him, sinking into a deep sleep.

He had to admit, it was the best birthday ever.
