Summary: Gil is a man with a mission.


The blindfold was the hardest to take. It wasn't that Nick didn't trust his Master, because he did. It was more that he could never tell what the devious man would do next and that made it all the harder for him to control his own body. Since coming through his surgery with flying colors, Gil had been a man of renewed energy. Every part of his life had exploded into overdrive and for the week directly following the recovery, Nick had barely been able to sit, thanks to the constant Claiming and the spankings.

The Claimings had slowed down to only once every couple of days, though Gil kept him busy in other ways. He could now make his Master come in a matter of minutes using just his mouth. Given the other man's strength of will, that was a feat Nick was very proud of. He could also dress and undress his Master with only his mouth. And just watching his Master take out the crop now stirred his arousal, dropping him to his knees in anticipation. They'd graduated from hand, to crop and Nick had enjoyed every encounter. It was as though something drove Gil to impart these lessons to him on a timetable of which he had no details.

Not that he minded in the least.

"Ready, Nicky?"

Nick cleared his throat and answered clearly, "Ready, Master."

A faint whistle echoed in the air a split second before fire laced across his ass. Nick yelped in shock, stumbling forward and losing his position completely. Immediately stepping back, Nick apologized, "I'm sorry, Master."

"It's all right, Nicky. I didn't give you much warning," Gil soothed, kissing his bare shoulder. "I wanted to see your reaction."

"And?"

"Beautiful, as always."

Nick flushed happily, took a breath and spreading his legs a bit for a firmer stance. "I'm ready, Master."

Gil made an approving noise and the whip hurtled through the air again, slicing the opposite way across Nick's ass. He grunted with the pain, but breathed deeply, knowing that it would go on as long as his Master wished it. And because his Master wished it, so did Nick. By the time it was over, Nick's body shook with fatigue and endorphins and he felt absolutely high on drugs, even though he'd never taken any.

Rubbing his shoulder, soothing, Gil praised, "So perfect, so good my boy. You did absolutely wonderfully."

Nick leaned into the other man's arms, which had wrapped around him, and sighed happily as he asked, "Do we have to stop, Master?"

Chuckling, Gil replied, "We do. I've got a lovely star pattern across your ass and I bet you can guess what lies at the center."

"Will you Claim me now? Please?" Nick begged. "It'll feel so good. I bet you just slide right into me."

Voice rougher, Gil bit sharply at his throat and answered, "Not tonight, baby boy. I have something else in mind. I'm going to bring you to the bedroom now."

Nick went readily, even as his body started to come down from the natural high. When they got to the bedroom, he could barely drag his feet forward, though he did so until Gil told him to stop. He was lain gently over the bed, face first, feet on the floor, and gratefully sank into its comforting softness. While he could hear his Master puttering around the room, Nick didn't bother to try and nudge off the blindfold to see what was going on. It was therefore a complete surprise when something hard and cool and big pushed inside his ass. It was easily wider around than his Master's cock. Startled and a little apprehensive at the serious stretch, he questioned, "Master?"

"It's okay, Nicky, just relax. Let it inside you, baby."

Nick took a few deep breaths, relaxing as much as he could while the dildo entered his body inch by incredibly long inch. When it finally bottomed out, Nick felt painfully full and panted in short, sharp breaths to try and relax.

"So good, Nicky, so good. That's it, relax for me. I know it's uncomfortable, baby, but just take your time and get used to it," Gil soothed. "You're doing great."

It had certainly taken his attention off the throbbing welts left in place by the whip. Moments after the dildo was in place, cold lotion dripped onto his hot ass and was rubbed carefully into the raised flesh. Nick moaned at the multitude of sensations and shifted under the steady touch, unable to take the split-apart feeling anymore. "Master, it's too much, please, I can't, I can't take it all."

Right away, the dildo was slowly and carefully removed. When it was out, Nick breathed a long sigh of relief and then bit his lip in shame as he apologized, "I'm sorry, Master. I'm sorry."

Gil took off the blindfold and immediately cupped his face, kissing him sweetly before saying firmly, "You have nothing to be sorry about, Nick. You did really, really well."

"But I couldn't take it," Nick protested.

Kissing him again, Gil told him, "I'm testing your limits, Nick. There's no right or wrong here. Just be honest with how you feel and what you can't do. Promise?"

Relieved, Nick nodded and offered a smile. "Promise."

"Good. Now let's get you into bed."

"Um, I really have to pee first."

Gil chuckled. "I'm not surprised, having all of that inside you."

Pushing upright, Nick glanced at the large, flesh-colored dildo and gaped at its size. "You got that inside me?"

"And some day soon, you'll be able to keep it inside you," Gil replied, a gleam in his pale eyes.

Nick gulped, giving the silicone cock a wary look on his way to the bathroom.

Greg whistled as he walked down the lab hallway, patting his rounded belly now and again. He was officially over the first trimester and back to normal, aside from the weight gain. Warrick had been reluctant to let him go back to work, but he'd begged shamelessly and sucked him off every chance he got. The combination had worked, but barely. As it was, he had to check in with Warrick every two hours or he wouldn't be allowed to keep going to work.

Catching sight of Nick as the other slave moved gingerly down the hall, Greg's eyebrows rose at the obvious discomfort. "Yo Nick!"

Nick jumped, then groaned as he turned around. He gave Greg a half-hearted glare and asked, "Could you not do that please?"

Greg smirked. "Someone's been ridden hard and put away wet. Ah, how I long for the days."

Instead of joining in, Nick grimaced and sighed as he complained, "Not even, man. I mean, I love my Master, but I don't know what is going on in his head these days."

Surprised, Greg looked around the mostly empty hall and decided it wouldn't be good to talk about whatever it was right there in public. Putting his hand to Nick's hip, he guided the slave to a supply closet and closed the door.

"Greg, what are we doing here?" Nick questioned, frowning.

Greg put his arms out and assumed a Norwegian accent as he ordered, "Tell Papa Greg what's troubling you, little Nicky."

Nick looked at him like he was nuts and demanded, "Are you off your nut?"

Laughing, Greg wagged a finger at him. "If Grissom could hear you now."

"This is stupid. I'm leaving."

"Nick, wait," Greg relented. "I'm sorry. Come on, tell me what's wrong."

Nick sighed, then admitted, "I don't know. Gil hasn't Claimed me in over a week, but he's taken to...ah...he's got this, well, fixation I guess..."

Greg's intrigue jumped sevenfold at the hot blush that suffused Nick's face as the other slave tried to say what Grissom was doing to him.

In a low rush of words, Nick exclaimed, "He keeps putting this huge dildo up my ass and making me keep it in for as long as I can, but he won't, he won't you know, fuck me anymore."

Before Greg could even think of a response, the closet door opened and Grissom himself stood on the other side of it. Greg instantly ducked his head, embarrassed at being caught gossiping by the man himself.

"To what do I owe this little cabal?" Grissom questioned, amusement plain in his voice.

Nick cleared his throat and answered, "Ah, Greg was just talking to me about something private."

Nice evasion, Greg thought in admiration. Completely true, but also a complete misdirection.

Grissom's eyebrows rose askance, but he only said, "Time to go, Nicky. My meeting's over."

As Nick walked carefully down the hall, it suddenly occurred to Greg what Master Grissom was up to. He sighed jealously and muttered, "You lucky dog, you," before ambling back towards the DNA lab.

* * * *

"That's it, Nicky, just listen to the sound of my voice and relax."

Nick sighed deeply again, breathing in and out in meditative rhythms as he let himself sink into the soft cushions. Stretched out on the living room floor, surrounded by aromatherapy candles, eyes closed, body naked and his ass filled with that dildo which had seemed so very big and impossible before, Nick listened.

"There is only me right now. I am the center of your universe when I say...what?"

It was a struggle to make himself answer, "Rollercoaster."

"Good boy. When I say rollercoaster, you will count backwards from ten and with each number, find yourself in this relaxed, contented state. You'll remember how you feel right now and return to this place and time. Nothing can hurt you, nothing can upset you, and you'll follow my direction to the letter."

Nick nodded dreamily. "Yes, Master."

"Such a good boy, Nicky. I love you so much. Now, what do you say if you get scared or need to stop what's going on for any reason?"

That word came easier, since it had been drilled into him far longer. "Crane."

"Excellent. That's perfect, Nicky."

Nick wanted to arch into the hands on his body as his Master caressed his chest in slow, languid strokes, but couldn't. He'd been told to stay perfectly still. Soft kisses touched his skin and then his hard cock was taken into his Master's mouth and he moaned, eager for more. It was so hard not to move, but he did so to please his Master. His cock throbbed even more as Gil licked and sucked on it like a piece of candy.

Gentle fingers rolled his balls and then rubbed behind them and he gasped, aching to come. Nick kept a tight rein on himself, though it was so difficult. He wanted to do this right. Wanted to be perfect for his Master.

The suction increased and teeth edged playfully along his length, provoking a cry of need he couldn't stop. He struggled desperately to stay still, not to move as his balls were massaged and squeezed. Nick managed to keep control even when his Master went all the way down on him, throat enveloping his dick in wet heat. It wasn't until his Master swallowed rapidly around his cock that Nick lost it and came with a shout of release.

He didn't, however, move a muscle.

* * * *

Nick groaned and sweated as Gil slowly worked the large dildo into his ass. The young slave was panting softly, straining to take the next size up, now that Gil had adapted him to the first. Three and a half inches in diameter and ten inches in length, it was an inch wider and two inches longer than the first. Gil's cock throbbed with the need to pull it out and take its place, but he restrained himself ruthlessly. They had another week to get Nick accustomed to the bigger size and then it would be time for the main event.

He'd debated on telling Nick or not, but decided ultimately that telling the slave would only lead to an inordinate amount of stress and worry. Keeping it simply as an odd desire of his own had Nick eager to please, if baffled by the change in their sex life.

When he finally got the silicone cock all the way in, Nick collapsed onto the bed completely, moaning. Gil had left the last dildo inside him overnight, so this actually wasn't too bad despite the difference in size. "Nicky? Are you all right?"

"If I move, I'll come," came the muffled response.

Grinning in delight, Gil deliberated pressed in on the dildo.

"Master!"

He did it again and Nick jerked violently, crying out in wordless pleasure as he arched back in beautiful orgasm, muscles straining. Unable to help himself, Gil shoved his pants partially down and masturbated until he came over Nick's upturned ass and the fake cock pushed so deep inside his slave.

Panting harshly as he leaned on the bed for support, Gil murmured, "So perfect, baby."

* * * *

The club parking lot was moderately crowded as Gil pulled into a parking spot outside the respectable looking building just outside the city. Looking like not much more than an average, if expensive seeming restaurant, the club actually housed much darker activities and entertainment for the elite Masters of the city. Run by a stunning woman known only as Lady Heather, though Gil didn't know if that was an actual or an assumed title, the club had no name and entry was only gained if someone vouched for the petitioner.

Turning to Nicky, who looked curiously at the building before them, Gil said, "I'm introducing you to society tonight, Nicky. What you do in there, reflects on me personally."

Nick swallowed nervously.

"Do you trust me?" Gil questioned softly.

Nick nodded and answered, "With my life, Master."

Smiling, Gil promised, "Nothing nearly so dire, baby. Just trust in me and your lessons and everything will be fine. You'll be the belle of the ball."

Gil took a slow, lingering kiss from his slave, leaving Nicky dazed and heavy-lidded. Smiling, he murmured, "Rollercoaster."

The change was almost instantaneous and incredible to witness. Nick's eyes closed and his mouth opened, just a little. After the span of ten seconds, those hazel eyes reopened and Gil's breath caught in his throat at the heat therein. Shivering, Gil leaned in and kissed him again, hungrily this time. It was only the knowledge that people were waiting on them that prompted him to pull back. He growled possessively at the submissive look in Nick's eyes and ordered, "Out of the car and take off your pants."

Nick obeyed immediately and Gil took a few seconds to get himself under control. It wouldn't do to arrived all hot and bothered. Not with the night he had planned for them. Climbing out of the car, he walked around to the other side and found Nick naked, save for the leather chastity belt he'd purchased.

Taking the pants from his slave, he tossed them in the car and said, "Two steps behind me at all times. If someone touches you, it's all right. Let them. If they try to do more than that, draw my attention respectfully to the situation. Eyes down at all times. You do not speak unless I tell you it is all right to do so. Kneel when I stop to speak to someone. If you need to relieve yourself, or need a quiet moment with just the two of us, tap me twice on the right shoulder. Do you understand your instructions, Nicky?"

"Yes, Master," Nick murmured respectfully.

Gil smiled. "Good boy. Let's go inside, then."

The interior of the club was just as tasteful as the exterior and reminiscent of Rome herself. Opulence was the key word and Gil took in the familiar trappings at a glance just to see if anything had changed. The color scheme was a little more muted, but otherwise, it was the same as the last time he'd visited.

"Master Grissom, there you are!"

Looking over at Lady Heather, resplendent in a form-fitting silk gown that teased in what it hid, and what it showed, Gil smiled and held out a hand. "It's good to see you again, Lady Heather. You look amazing, as always."

She smiled brilliantly and kissed his cheek. "And you. Look at you now. I told you all you needed was someone to put all that incredible focus on and you would find out what living really means. You're practically glowing."

Gil chuckled. "Thank you."

"And this must be the famous Nick about whom I've heard so much," she murmured, looked down.

Stepping to the side, Gil let her look her fill and said, "You can pet him, if you like. I've been giving him some intense training over the last month."

"Mmm. So I see."

Gil watched closely as she gently brushed her palm over Nick's soft, short hair.

"He is lovely," she praised. "And so obedient. Maybe you should have Jackie's job."

Shaking his head, Gil replied dryly, "I'm fine where I am, thank you, Lady Heather."

"A pity. Will you be showing him later?"

"I will."

"Supplies?"

"I'll need to use your horse."

"Ooh. I am intrigued. It's in the gray room, now. Shall we say one hour?"

Gil nodded. "That sounds perfect. I'll have time to mingle."

She smiled in return and nodded, before commenting sotto voce, "Not that you enjoy mingling, but at least you're finally making an effort. Good boy."

Chuckling, Gil headed for a small cluster of men he knew from his brief time on the local Council. He didn't look to see how Nick did with his instructions, instead trusting the slave to make him look good. From the covetous glances he received on the way over, Gil knew his trust had not been misplaced.

The hour went by quickly, to Gil's surprise. He kept a careful eye on Nick as strangers touched and admired him. He had a lively philosophical debate with a visiting professor and talked in depth to a local carpenter who had red ant problems on his homestead. When the time came, he excused himself and headed for the grey room, by way of a restroom. In the privacy of the small, single toileted room, Gil pushed Nick against a wall and kissed him fervently, passionately, and felt his slave's cock rise to the attention. Smiling caused their teeth to click together and he pulled back to find a pleasant flush all along Nick's neck and face.

Caressing the young man's face, Gil told him, "We're going to do two things tonight that we've never done before, Nicky, and I'm giving you the opportunity to say no right now. Do you understand me?"

Nick nodded, some of the heat replaced by a firmer reason.

"The first thing is I'm going to take off the chastity belt and you will walk out there completely nude and hard. People will touch you because they have implicit permission to do so, due to your nudity. Are you comfortable with that?"

Frowning, Nick hesitated a long moment, but then nodded and agreed, "Yes, Master."

"Good boy," Gil praised, smiling. "Now, the second will be harder. Have you heard of fisting, Nicky?"

From the sharp intake of breath and shocked widening of his eyes, it was obvious that Nick had.

"We're going to go out there and I'm going to bend you over a leather cushioned gymnastic horse and I'm going to put my fist inside you. I'm going to fuck you right here in front of those people, with my fist, and make you come. Are you comfortable with that?"

Nick cleared his throat and asked, "Is this, is this really something you want, Master?"

"It is," Gil told him. "I love having control of you, you know that. I want to show my peers just how much I own you, simply because you're willing to let me have my way with you. That you love me and wish to give me whatever I want."

Closing his eyes, Nick didn't say anything for a long moment and Gil let him think it over. This was a big thing he asked, and he wouldn't pressure the slave in any way.

Finally, Nick's eyes opened again and he offered a hesitant smile as he said, "If this is what you want, Master, then I want it too."

Hissing in a combination of pleasure, gratitude, and arousal, Gil kissed him again, devouring him as fully as possible in the short time they had left. A discreet knock at the door alerted him that all was ready and he pulled back, calling out hoarsely, "We're almost ready."

With reverent fingers, he pulled out the golden lock to the chastity belt and unlocked it. Gil carefully pushed the leather down, pulling the dildo gently from Nick's ass and then setting the apparatus on the nearby table. While the silicone shaft in the chastity belt wasn't nearly as big as the ones they'd been using, it had been enough to keep Nick slick and nominally ready. Gil stroked his hand along his slave's dick, making it good and hard, and then stepped back. Staring into now dark eyes, he murmured again, "Rollercoaster."

Nick's eyes closed and he sighed deeply, tension visibly leaving him, though his cock remained hard. They opened only slightly, giving Gil such a hot invitation that he seriously had to stop himself from simply bending Nick over the table and Claiming him then and there. Shaking off the need as best he could, Gil turned sharply and walked out of the bathroom.

He heard the excited conversation around them as they headed for the gray room a short distance away, but ignored it. The horse had been adjusted to the right height and he gave Lady Heather a thankful glance before ushering Nick onto the dais. He gently bent Nick into position, his backside facing the crowd that had gathered, slaves, Masters, and Mistresses alike eager to see this new exhibition. Not only had Gil never participated in one before, he'd never even owned a slave. They were all curious, he knew, to see how a reputed abolitionist would have handled acquiring and training a slave.

Rubbing his hand over Nick's rump, he turned to the table that was mere inches away, selected a latex glove that went to the elbow and pulled it on. Dipping two fingers into the jar of lube, Gil returned to Nick and gently pushed two fingers inside the small, defenseless hole. They went in easily and he twisted and turned them inside, smearing the lube everywhere he could. Re-supplying with more lube, Gil pushed three fingers in and smiled when Nick merely sighed and wiggled his ass, causing an amused wave of chuckles to run through the crowd.

"Good boy," Gil told him, still smiling.

Four fingers was more difficult and he took his time to twist and turn his hand, keeping an eye on his slave as he opened the young man more fully. Sweat broke out along Nick's back, but he only grunted a couple of times in discomfort. The training had, it seemed, paid off. Withdrawing his hand, this time he dipped the hole thing in the jar, including his thumb, and rubbed it up over the wrist and forearm. Gil pushed the four fingers back inside and leaned forward to ask, "You all right, Nicky?"

Nick nodded firmly and replied, "Yes, Master. Please take me."

Arousal surged through him, but Gil kept to the slow and stead pace as he folded his thumb and introduced his entire hand to Nick's hole, oh-so-carefully pushing passed the guarding muscle. A sigh of approval went through the gathered people, but Gil ignored that, too. The sensation of having his entire hand surrounded by Nick was...mind-blowing. He felt their pulses throbbing together, slightly out of synch and had to close his eyes to keep control.

Gil pumped his arm forward and back with the utmost attention to his slave. His eyes burned from lack of blinking as he watched Nick's back strain and felt he rectal muscles tighten involuntarily around his wrist and then his forearm.

"OhGod..." Nick sighed, shuddering suddenly.

Fierce elation lit through Gil when Nick came so unexpectedly and he deftly fucked his slave with his hand to draw out the sensations. He didn't go any deeper than the middle of his forearm, exactly the length of the last dildo, but twisted and turned his arm in slow circles. Nick cried out and came again, semen spurting onto the floor. And still, Gil didn't stop, driven to pull one more orgasm from his slave. Driven to possess him utterly.

Bending forward, he bit Nick's shoulder hard and then ordered harshly, "Come, Nicky!"

Shouting loudly this time, Nick spasmed back onto his arm, fucking himself on Gil in a dry orgasm. His hole bore down on Gil's arm painfully tight until Nick simply collapsed, relaxing forward onto the horse in a faint.

Gil cautiously pulled his arm from Nick bit by bit, withdrawing completely with a sigh. It's just as well he passed out, Gil thought, giddy. I'm in no shape to take care of him right away.

Despite the high that lifted him, Gil did take care of his slave right away. After disposing of the latex glove, he checked Nick for any injury that might've occurred during the fisting and breathed a sigh of relief on finding none. Assisted by two of Lady Heather's larger slaves, he got Nick down from the horse and into the nearest bedroom. It wasn't until he'd stretched out beside his slave that Gil realized he'd come in his own pants like an undisciplined teenager.

Gil held Nick tight, his slave still out of it and draped over his chest, and thought that it couldn't get any better.

* * * *

Waking up turned out to be a mistake. Nick groaned as pain instantly assaulted his entire ass without him even moving.

"Nicky? Are you all right, baby?"

Nick opened his eyes and squinted blearily at his master. "I hurt."

"I know, Nicky. I've got a nice hot bath waiting for you and that'll help," Gil promised.

"I can't move, Master, it hurts too much."

He winced and hoped that didn't sound so much like a whine to his Master, as it did to him. Even though he really didn't want to move, Nick allowed himself to be cajoled and helped from the bed to the large, sunken tub in the attached bathroom. Sinking into the bubbling water, Nick hissed as the heat immediately sank into his body. Gil lowered down with him, directly behind him, and in a few minutes, they were both mostly underwater.

Laying back in his Master's arms, buoyed by the water, Nick slowly relaxed. Letting his head loll to the side, he asked, "Did it turn out how you wanted, Master?"

"Oh yes, Nicky. It was so much more," Gil replied, nuzzling at his throat. "What about you? Is that something you might want to do again?"

Thinking about the feel of his Master's arm inside him, their pulses almost completely in synch, Nick had to smile and nod. "I would, Master, but..."

"But?"

"Can we wait for a while? My ass really hurts."

Gil laughed, a warm, deep belly laugh and then nipped playfully at Nick's ear as he agreed, "We'll let you decide the next time we do it, how's that?"

Smiling in contentment, Nick nodded sleepily and pulled Gil's arm over his shoulder and curled into it thinking, It just can't get any better than this.
