Two Masters
By Xanthe
Part Seven

He was lying in Gibbs's arms, in Gibbs's bed. His dom was kissing the back of his neck and slowly petting him, running his flat, purposeful hands all over his naked body. It felt SO damn good.

"Get up." A voice penetrated his dreams, demanding obedience.

"Hmm?" he muttered, burrowing under the blankets. He didn't want to get up. He wanted to stay here, in the warm cocoon of Gibbs's arms.

"Up." The voice was speaking directly into his ear, tickling him. He batted it away.

"In a minute, Boss," he mumbled. "Busy right now."

A second later the blanket disappeared, he was pushed onto his front by a pair of strong hands, and his bottom was slapped – hard. Once, twice, three times…

"I'm up, I'm up!" he yelped, immediately snapping into wakefulness.

He was lying on the mattress on the floor – he hadn't slept in Gibbs's bed except in his dreams. He had been hopeful that Gibbs would allow him to sleep in the bed after the intimacy of their time on the couch last night, but no. Gibbs had just raised an eyebrow when Tony had tried to get into the bed and had jerked his thumb in the direction of the mattress on the floor instead.

And that was where he'd spent the night, right up until he'd experienced Gibbs's unpleasant morning alarm call. Those slaps continued to rain down on his naked butt, and Tony rolled sideways to escape them. He ended up on his ass and remembered – too late - the butt plug Gibbs had inserted there. He gave another yelp and quickly scrambled to his knees. He looked up and glared at his top. Gibbs was standing over the mattress, fully dressed and ready for work.

"What's rule number one?" Gibbs demanded.

Tony continued glaring at him. "Obey you?" he muttered gracelessly.

Gibbs raised an ominous eyebrow. "And rule number three?"

"Instantly," Tony sighed. "Even in my damn sleep," he muttered under his breath.

"So, that's three for the chalkboard," Gibbs told him. "And it isn't even 6 a.m. yet. Good going, Tony." He held out his hand. Tony glanced at it sourly but eventually took it and allowed Gibbs to pull him to his feet.

"Three? How d'you figure that out?" he complained as he got up.

"One for disobedience, one for slowness, and one for attitude," Gibbs reeled off flatly.

"You already spanked me for the first two," Tony argued, knowing that he should really be keeping his mouth shut at this point, but damn it, that was a really lousy way to wake up. Especially when he’d had to sleep on a mattress on the floor all night instead of in a warm, cosy bed - and with a goddamn butt plug stuck up his ass too. He wondered if Gibbs had treated Stan like this and felt a surge of anger.

"No – I spanked you to wake you up. Punishment is separate," Gibbs told him. "Now, come here."

"Why?" Tony asked cautiously, suddenly aware that he was stark naked and every inch of his naked flesh was available for Gibbs to do something to. He wasn't sure if that was a good thought or a bad one.

Gibbs raised an eyebrow again. Tony hopped over to him immediately.

"You're not a morning person, are you?" Gibbs said, with a wry little shake of his head.

Tony sighed. "No, Boss. I'm really not."

"Wanna start again?"

"I'd really like that," Tony admitted miserably.

"Good."

Gibbs pulled Tony close and kissed him firmly on the mouth. Tony sighed. This was definitely a better start to the day than the previous one. Gibbs kissed him until he relaxed, and then he released him and pushed him in the direction of the bathroom.

"Go take a shower. You can remove the plug. Then come downstairs – naked – you've got fifteen minutes."

Tony made sure to glance at his watch and note the time, and then he ran for the bathroom, throwing a hurried "Yes, Boss!" over his shoulder.

He took a shower and then stared at himself in the bathroom mirror as he shaved and cleaned his teeth. He remembered how it had felt to have Gibbs hold him like he actually cared about him last night. That hadn't been about sex – it had felt like something deeper and more affectionate. That wasn't anything he'd expected from Gibbs – and now he couldn't get it out of his mind.

He knew Gibbs would laugh at him, tell him he'd gone soft, and possibly even slap the back of his head for it, but he couldn't help wanting more of whatever it was they'd shared on the couch last night.

Had Gibbs ever held Stan like that? He felt that surge of anger again. He knew he was jealous of his predecessor in every single way, but he couldn't seem to help himself. He had met Stan – he knew what the guy was like. He was good looking, smart, witty, great at his job, and no doubt as good a sub as he was as an agent. He probably hadn't made any unreasonable demands for intimacy on Gibbs. He had probably just taken what he was given and never once been needy.

Tony fought down that sense of neediness in himself. Gibbs had made it damn clear that he was a sub and nothing more. Not a boyfriend or even a lover – just a submissive.

That thought made his cock ache, and he considered wrapping his hand around it and bringing himself off. He wanted to – God knows he wanted to – but he didn't have much time, and besides…he didn't know what Gibbs had in store for him in the next hour. If he jacked off, and then Gibbs touched him, and he couldn't get hard again, then Gibbs would know for sure. But fuck it, he wanted some sexual release after all the excitement of yesterday. Gibbs had got off – it wasn’t fair that all Tony got was a bad case of blue balls.

He wrestled with himself and then finally decided against it. Gibbs couldn't watch him every second of the day. There had to be a moment when he could sneak off to the men's room and spend some quality time with his cock, just the two of them.

He finished up and ran down the stairs, reaching the kitchen on the dot of the fifteen minutes Gibbs had given him. There was a cup of coffee and a plate of food waiting for him. Gibbs had already eaten his, judging by the empty plate in front of him. Tony looked at the food and then at Gibbs.

"Problem?" Gibbs asked.

"Just not hungry this early, Boss."

"Okay." Gibbs shrugged. "That saves time. Eat later. Now, listen up, Tony. Just because we're gonna be at work all day, doesn't mean you're not my sub. Are we clear?"

"Clear, Boss," Tony nodded. "Are there any more special rules I need to be aware of?"

Gibbs gave an impatient little jerk of his head. "Nope. But I'll be sure to let you know if you do anything wrong."

"Yeah. Like always," Tony muttered.

He watched as Gibbs opened up a bag lying on the table and drew out two items that made Tony's heart skip a beat. One was a butt plug, slightly bigger than the one he'd worn all night. The other…was some unidentifiable contraption made of strips of leather.

"Uh – what's that, Boss?" Tony pointed.

"This?" Gibbs held it up, a malicious grin on his face. Tony had a feeling he wasn't going to like this. "This is a chastity device, Tony."

Tony held onto the back of the chair as the room seemed to lurch around him.

"You sure you don't want any breakfast?" Gibbs asked. "You look pale. Low blood sugar?"

"Uh no…just…chastity device?" Tony squeaked.

"Yeah – you didn't think I'd just trust you not to disappear into the men's room during the day and jack off, did you?" Gibbs chuckled.

"Well, yeah, I did, as a matter of fact," Tony retorted, with an air of wounded pride. Damnit – how had Gibbs *known*. "Isn't this whole thing about trust?"

"Yup." Gibbs nodded pleasantly. "And when you trust yourself then I'll trust you. Do you trust yourself to obey me on this?"

Tony thought about it and then gave in with a sigh. "No, Boss," he admitted finally.

"Yeah. That’s what I thought. Now get your ass over here." Gibbs beckoned, and Tony walked slowly over to him. When he got there, Gibbs reached out and put his hand on Tony's naked shoulder. Tony stood there, fighting to stay still, his muscles tense.

Gibbs frowned. "Who do you belong to, Tony?"

"You, Boss," Tony said automatically.

"When?" Gibbs was looking at him intently. Tony wondered what the hell that question meant.

"Uh…24 hours a day, seven days a week?" he hazarded.

"Exactly. So why…" Gibbs moved his hand suddenly, and Tony flinched. "…What's going on, Tony?" Gibbs demanded.

"Nothing," Tony shrugged.

"That's another one for the chalkboard. What's rule number two?"

"Don't lie to you," Tony sighed, wondering whether he was ever going to catch a break this morning.

"Then tell me what the hell is going on," Gibbs growled.

"Is this what you did with Stan?" Tony asked, unexpectedly. "Is this how you played it with him? The chalkboard, the not coming thing, the buttplug, the whole weird chastity device – hell, even the fucking mattress on the floor? Is this just a new dog – old tricks kind of thing for you?"

Gibbs went very still, and he suddenly seemed far too close. Tony bit on his lip.

"You done?" Gibbs asked quietly.

"No." Tony decided that he'd already screwed up badly, so he might as well go the whole distance. "Why can't I sleep in the goddamn bed with you? Last night…" he broke off, annoyed with himself.

"Go on," Gibbs ordered.

"Last night on the couch…" Tony felt himself flushing. "That was good. Then you made me sleep on the floor again."

"Anything else?" Gibbs asked, in that same deceptively quiet tone of voice.

"Nope. Now I'm done."

Tony thought his outburst might have lost a little impact in view of the fact that he was standing stark naked in his boss's kitchen while Gibbs was fully clothed and dressed for work. He gazed at his own bare feet, feeling vulnerable and exposed in every way possible.

"Okay. In answer to your question – no, this isn't how I treated Stan. You and Stan are about as different as can be. For a start – Stan didn't stay over. Ever."

Tony's head jerked up in surprise.

"Stan and I played – at a club, and occasionally at Stan's apartment, and sometimes here, but that's it. We played, but Stan never stayed over, and I never stayed over with him, either. It wasn't like that between me and Stan. That was partly the problem."

"Why was it a problem?"

"Because I knew that to work for me it had to be 24/7, and Stan – he actually wanted that, but I wasn't ready for it – at least not with him. That's why it didn't work out between us."

Tony bit on his lip some more. "You ever play with Stan at work?"

"Nope." Gibbs shook his head. "We only ever played in sessions of a couple of hours or so outside work. I won't play with you at work, either, but that's ‘cause I expect the same things from you at work as I do at home. So it's not play."

"Okay." Tony nodded. "You want me to add something to the chalkboard for me being an ass?"

"I'm not done yet. You need to figure out if this is what you really want, Tony. You're in charge of that decision – not me. That's what this week is about. I’m trying to give you a good idea of what it’s gonna be like. Any time you want it to end, you just tell me, and it ends. Or any time something is too hard for you, you use your safe word, and you know I'll stop whatever I'm doing. You do know that, right?"

"Yes, I know that.”

"Good. *Now* you can add one to the board for attitude."

"Just one?" Tony raised an eyebrow.

"Yeah – the rest was being honest which is actually a rule, so I'm not gonna punish you for that," Gibbs told him firmly. "Are we done with this now, DiNozzo?"

“Uh – almost. What about the sleeping in your bed thing?”

“You can sleep in my bed when you’re collared and not before,” Gibbs replied. “And you should be careful what you wish for, Tony.”

“What does that mean?” Tony asked, intrigued.

“You’ll see,” Gibbs grinned. “*Now* are we done?”

"Sure." Tony grinned brightly. Gibbs tousled his hair, and Tony leaned into the caress happily, feeling better than he had since he'd woken up. "And, uh, sorry, Boss. I'm *really* not a morning person."

Gibbs chuckled. "Ya think, DiNozzo?"

He sat down at the kitchen table, pulled Tony close, and then placed a hand on his cock – which sprang immediately to life.

"I really hate the whole not coming thing," Tony sighed.

"I know." Gibbs sounded smug as he said that, and Tony wished he could smack *him* on the back of the head occasionally.

Gibbs threaded Tony's cock into the leather contraption and then fastened it around his balls. Tony's cock strained eagerly at the leather confines, but it wasn't going anywhere – it was completely imprisoned. Gibbs added a tiny padlock and locked it in place.

"Just in case you had one of those not being able to trust yourself moments," he told Tony with a grin as he snapped the padlock shut. Tony just glared at him. "You can piss through the end of it, but there's no way you're gonna get an erection until I take this off," Gibbs informed him, tapping his imprisoned cock firmly.

Tony glanced down at himself. His cock was well and truly encased in the tight leather confines of the device. The only way out, other than using the key, was to hack at it with a knife or pair of scissors, and there was no way Tony was going to allow anything sharp that close to his nether regions. So, he had to resign himself to the fact that when Gibbs said he couldn't come, he really meant it.

He felt a wave of sweat break out over his body as the reality of that thought struck home. His body really did belong to his dom. Gibbs had control over when – and if – he got to come. It wasn't his choice any more. There was something about that idea that turned him on mentally as much as physically. Once he'd fought – and won – that battle with himself, he felt much happier. At least Gibbs had never demanded that degree of control over Stan's body. He'd never strapped Stan into a device like this, or allowed him to sleep on his bedroom floor.

"You and Stan ever…" he began, before he could stop himself. "Uh…you know, just sit on the couch together, like we did last night?"

Gibbs exhaled loudly, sounding exasperated. Tony made another little face.

"No, Tony," Gibbs said, standing up and pulling Tony so close that their noses were almost touching. "I played with Stan, and he was good – the perfect sub – very well trained, but we never cuddled, snuggled, or whatever the hell it was you and I did last night. Now bend over the table."

He pulled on Tony's wrist and flipped him down over the kitchen table, and then he parted Tony's legs with his knee. Next thing Tony knew, another slippery butt plug was being pressed against his hole. He willed himself to relax and allow the damn thing in. It wasn't big, and he was already stretched from wearing one all night. Besides, Stan was the *perfect* sub, and there was no way Tony was going to be the crappy sub by comparison. If Gibbs wanted the perfect damn sub, then that was what he was going to get.

The butt plug slid home neatly, and Gibbs patted Tony's ass.

"Okay. We're done. You're ready. Get dressed – I don't want to be late," he ordered.

"Get dressed in what?" Tony asked blankly. "I don't have any work clothes here."

Gibbs pointed at the clean sweatpants and tee shirt on the chair. "Wear those. I'll drop you off at your apartment on my way to work. You have one hour to get dressed and pack enough work clothes to see you through the week – and any other things you might need. Put them in your car and bring them to work. You won't be going home again this week unless you want out."

Tony nodded. He'd been wondering how this would work, but it seemed that when Gibbs said 24/7, he really did mean it – he wanted Tony with him at all times. That was a good thought. Tony had always flourished with attention – it was being ignored that drove him crazy.

Half an hour later, Gibbs dropped him off at his apartment with a strict injunction that he be at his desk in one hour's time. Tony rushed into his apartment and quickly packed everything he thought he'd need for the week. Then he got dressed in a steel grey suit with a white shirt and a wide, purple tie.

When he was done, he looked at himself in the mirror. Last time he'd gone to work he'd just been a regular guy, but now he was owned by Gibbs. He gazed at himself thoughtfully. He looked the same as ever. Nobody would know that beneath this suit he was wearing a leather chastity device strapped over his cock and balls, neatly padlocked at the front, and completely irremovable except by Gibbs. And nobody could possibly guess that there was a rubber butt plug inserted into his hole.

Nobody else knew, but it was impossible for Tony to forget either of those things. They were so alien, so strange, so intrusive and so different that they kept his new status constantly at the forefront of his mind.

Tony was determined that he was going to do this. He wasn’t going to walk out before the end of the week, and he sure as hell wasn’t going to say his safe word. He was going to earn that collar, take his rightful place in Gibbs’s bed - and do his best to make Gibbs forget all about Stan Burley.

~*~

Gibbs glanced at his watch and then back at the report he was reading. Tony was cutting it fine; he only had another couple of minutes if he was going to… Gibbs glanced up to see that a cup of coffee had appeared mysteriously on the side of his desk. He looked around and saw that Tony was sitting at his own desk, typing assiduously, eyes fixed on the screen. Gibbs gave a little grin; he knew that his sub was a fast learner, but even so, he was impressed.

He took a sip of the coffee to find that it was exactly as he liked it – not that he’d expected anything less. After eight years working together, Tony knew how he liked his coffee. Gibbs glanced across the room again to find Tony looking at him. Gibbs gave him an approving nod, and Tony turned back to his work with a small, satisfied smile.

They were quiet all morning – the entire team was busy finishing up the paperwork from a case they had completed the previous week. Gibbs noticed Tony shift in his seat every so often, no doubt feeling the butt plug he’d put there. Gibbs wanted him to feel it. He wanted him to be in no doubt that his status had changed, and he had new responsibilities now.

Three hours later, Tony approached his desk holding the file containing his report. Instead of placing it on the desk, Tony crouched down beside him submissively.

“Here’s my report, Boss. Want me to wait here while you read it?” he asked. Gibbs liked the idea of Tony kneeling beside him while he read his report, but he decided it was too conspicuous.

“No – you can go back to your desk and round up all the ancillary reports I asked for.”

Tony nodded and got to his feet briskly. “On it, Boss!”

Gibbs read through Tony’s report slowly, noting that it was the best report Tony had ever presented to him. Clearly, Tony had taken onboard his message about the 24/7 nature of his submission – and he’d probably had the chalkboard in his mind’s eye while he’d been typing up the report.

Gibbs finished reading, got up, and walked towards the elevator. “DiNozzo – with me,” he barked, as he passed Tony’s desk. He saw Ziva and McGee exchange glances.

“I do not think Gibbs was very impressed with your report, Tony,” he overheard Ziva say as Tony got up from his chair.

“When is he ever?” McGee cracked. “Must be really bad if he’s taking you into the elevator to yell at you, Tony.”

“Why thank you, Probie dearest. Your concern for my welfare is duly noted,” Tony threw back at him. Then Gibbs heard him running up behind him.

The elevator doors opened, and they both stepped inside. No sooner had the doors shut than Gibbs turned, took hold of Tony, and pushed him back against the mirrored wall. Then he snapped his hand onto the emergency button, bringing the elevator to a creaking halt and plunging them into semi-darkness.

Gibbs kicked Tony’s legs apart and kept him pinned back against the elevator wall with his body, their groins pressed so close that he could feel the leather strapping around Tony’s cock through his pants.

“Uh…Boss – did I do something wrong?” Tony croaked. “I tried really hard on the report. Was the coffee cold?”

“No. The coffee and the report were both good. This is by way of a reward,” Gibbs purred in Tony’s ear.

He undid Tony’s tie, ripped his fingers through the top buttons of his shirt, and opened it. He put his hand in Tony’s hair, gripping it firmly, and pulled Tony’s head to one side, exposing his neck. Then he leaned in and kissed the soft skin. Tony gave a helpless moan. Gibbs held him in place and sucked down harder. Tony gasped, and his hands came up and grabbed hold of Gibbs’s hips. Gibbs nipped down gently on Tony’s neck, grazing the skin, getting Tony used to the sensation – and then, without warning, he bit down hard. Tony gave a squawk and convulsed beneath him, but Gibbs held him in place while he marked him.

Then he eased off. He sucked gently at the tortured piece of skin, and then licked at it tenderly, before finally releasing his grasp on Tony’s hair. He took a step back and looked at his handiwork. There was a perfect red bite mark on Tony’s neck. It marked him as Gibbs’s property, and Gibbs felt his cock swell at the thought of his sub bearing such a clear symbol of his ownership.

“Look.”

He swung Tony around so that he could look at himself in the mirror. Tony put up his hand to touch the mark, but Gibbs batted it away.

“Don’t touch – just look.” He traced the mark with his fingertips, watching Tony’s face in the mirror the entire time. “You're marked now,” Gibbs purred into Tony’s ear. "That's my mark on my sub."

The look of pleasure on Tony’s face made Gibbs’s cock harden even more. He leaned in and kissed Tony’s neck, sliding his hand down the back of Tony’s pants as he did so. He found the butt plug and pushed on it, watching in the mirror as Tony’s skin flushed a deep pink colour.

“One day, I’ll bring you in here and fuck this tight hole,” Gibbs promised, and he thought he would come from the expression on Tony’s face alone. “But for now…this will have to do.”

He turned Tony around again and pushed him onto his knees in front of him. Then he pulled Tony’s undone tie away from his shirt.

“Close your eyes,” he commanded. Tony obeyed instantly, and Gibbs fastened the tie over his sub’s eyes. Tony looked so good on his knees, with his dom’s bite mark on the side of his neck, blindfolded with his own tie, his hair dishevelled from where Gibbs had grasped it earlier.

“Open your mouth,” Gibbs ordered. Tony did as he was told with a little grin, clearly anticipating what was coming next.

Gibbs opened his fly and pulled his hard cock out of his boxers. He slid it between Tony’s open lips and sank himself deep into that warm, welcoming heat.

Gibbs used him as fast and hard as he had the previous day. Now was not the time to teach Tony the finer points of giving oral sex – now was just about reminding him who he was and rewarding him for his behaviour this morning.

He came with a low growl of pleasure and pumped down Tony’s throat. Tony swallowed gratefully and then licked his cock clean with little darts of his tongue, just as he had the previous day, without needing to be told. Gibbs allowed him this service and then withdrew and tucked his cock away in his pants again.

Then he leaned down and kissed Tony on the lips he’d just so comprehensively fucked. Tony moaned and pressed against him. He was so incredibly and pleasingly submissive. It was all Gibbs could do to tear himself away, but he forced himself to do it. He undid the tie from around Tony’s eyes, and Tony blinked up at him from happy, dreamy eyes.

“Enjoy your reward?” Gibbs asked.

“Yes, Boss,” Tony replied with a wide grin.

“Good. Now go get lunch for the team.” Gibbs pulled some bills out of his wallet and stuffed them into Tony’s jacket pocket. He saw Tony’s eyes flash. “What was that?” he asked.

“What was what?”

“That look when I gave you the money. Oh…” Realisation hit Gibbs, and he grinned. “You got a rent boy fantasy, Tony?”

Tony flushed. “Well I didn’t think I did until just now, Boss!” he complained. “But yeah, now you mention it, I think I do.”

“Good. We’ll play with that another time.” Gibbs patted his cheek affectionately.

He pulled Tony to his feet and hit the elevator switch to get them moving again. Tony started to button up his shirt, but Gibbs stopped him.

“Leave it. I want to see my mark on you whenever I look at you.”

“Boss!” Tony protested. “Ziva and McGee will give me hell if I come back from lunch looking like I just got laid!”

Gibbs grinned and patted his cheek again. “I’m sure you can handle Ziva and McGee, Tony.” He wrapped Tony’s tie around his hand and stuffed it into Tony’s pocket. “No tie. Shirt open so I can see that mark all day. And whenever I do, I’m gonna remember just how good you looked on your knees, blindfolded, marked, and with my cock in your mouth.”

The elevator doors opened, and Gibbs got out. He turned to see Tony standing there, mouth open, looking almost speechless.

“Problem, Tony?”

Tony shook his head. “No, Boss. Shirt open so you can remember what we did just then. I got it. You really are a bastard,” he muttered under his breath.

Gibbs grinned at him and was about to reply when Tony held up his hand.

“Yeah, yeah, I know, one more on the board ‘cause you really hate being called names – even when they’re true,” he added, just as the elevator doors closed on him.

Gibbs was chuckling away to himself as he walked the few steps to Abby’s lab. He felt relaxed and sexually satisfied; having a 24/7 sub definitely had its perks.

~*~

Tony returned to the squad room half an hour later bearing a bag of deli sandwiches. The top three buttons of his shirt were undone, and he could *feel* the bite mark on his neck, bright red and so very conspicuous. It might as well have been a neon sign. He was acutely aware of it, and his fingers twitched with the desire to pull his shirt over it. At the same time he liked how it felt – he got a surge of pride every time he thought about how Gibbs had "rewarded" him in the elevator. It had been hot, rough and exciting, and he loved having Gibbs's mark on his skin.

He quietly deposited Ziva's lunch on her desk and did the same for McGee without making his usual jokes. Then he approached Gibbs's desk. His top glanced up, and his gaze went immediately to the mark on Tony's neck. Tony was about to glare at him when he noticed that Gibbs wasn’t amused by his discomfort. Instead, he was looking at the mark with an expression of proud ownership. Tony realised that Gibbs had meant what he said back in the elevator – he really *did* want to look at the mark on Tony's neck and remember how he'd put it there. Tony placed Gibbs's lunch on his desk, and then he slipped silently back to his own desk and unwrapped his sandwich.

Ziva glanced up, looking surprised by the uncharacteristic silence in which lunch had been delivered.

"Thank you, Tony," she said politely, reaching for her sandwich. "I hope it is something edible this time."

"Hey – I thought you liked the peanut butter, chicken and mango combo I bought you last time!"

Her eyes narrowed. "I thought I made my feelings perfectly clear when I spat it out in your waste basket."

Tony took a mouthful of his sandwich and munched on it happily, grinning at her.

"How much do I owe you, Tony?" McGee asked, glancing up from his own work.

"Nothing – lunch was on Gibbs today," Tony said cheerfully.

"Uh, thank you, Boss," McGee said, his eyes wide with surprise in response to Gibbs's rare generosity.

"You all did a good job on the case – and I want the paperwork wrapped up by the end of today," Gibbs replied, barely glancing up from his work.

Tony clicked onto his emails and began reading, munching on his sandwich as he worked. He was so engrossed that he was oblivious to what was going on around him – until he looked up to find Ziva and McGee standing in front of his desk, arms folded across their chests, with dual raised eyebrows.

"What?" Tony demanded around his mouthful of sandwich.

"Is there something you would like to tell us, DiNozzo?" Ziva asked, her gaze fixed, none-too-subtly, on the bite mark on his neck.

"That's quick work even for you, Tony," McGee added, a smug smile on his face. "You were only gone for half an hour."

"Does your new girlfriend work in the deli, Tony?" Ziva asked.

"What makes you think I didn't have it when I came in this morning?" Tony asked, smiling at them pleasantly.

"It is possible – your shirt was buttoned then," Ziva mused. "But I think not. It looks too fresh for that."

"You know, Ziva – I think his new girlfriend is probably a vampire," McGee said, putting his finger up to his own neck and fingering it thoughtfully.

"You might be right, McGee," Ziva nodded. She leaned in close and examined the mark on Tony's neck. "Looks painful," she commented. "I hope she did not suck all your blood, Tony."

"We wouldn't want you fainting at your desk this afternoon," McGee added.

Tony glanced across the room to where Gibbs was sitting, reading through McGee's report. To all intents and purposes, he looked completely disinterested in the conversation currently going on around Tony's desk, but Tony saw the little glimmer of a grin on his lips. Well two could play at that game. If Gibbs was going to have some fun with this, then Tony sure as hell was too.

"Aw, I think the 'all-my-girlfriends-are-virtual’ probie and the 'never-gets-out-much’ Mossad officer are jealous," Tony said, sitting back in his chair and flicking open his shirt even more to completely display the mark. "I'm guessing it's been a while since either of you got laid," he added in his most patronising tone. He put his hands behind his head and grinned at them.

"You know, some of us manage to keep the details of our private lives to ourselves," McGee retorted. "That's why they're called *private* lives, Tony."

"Was she hungry, Tony?" Ziva asked, pointing at the bite mark. "That is a very deep bite. I think she must have been starving."

"Ravenous," McGee agreed.

"Well, it is lunchtime," Tony pointed out.

"And it looks as if *you* were on the menu," Ziva said archly.

Tony laughed. "Can I help it if I'm irresistible? Or if someone found me good enough to eat?" he purred, waggling his eyebrows suggestively.

"That is disgusting." Ziva made a face.

"Aw – you *say* that, but really you want all the juicy details," Tony grinned.

"I do not!" Ziva protested.

"I do," McGee said eagerly.

"McGee! Do not encourage him!" Ziva said reprovingly. Then she perched on the side of Tony's desk, her head on one side, her gaze fixed on the bite mark. "Okay," she sighed. "Tell us everything. Now!"

"Don't leave anything out." McGee sat down on the side of the filing cabinet behind Tony's desk. "What's she like? How old is she? Please tell me she's at least thirty this time, Tony."

"Definitely at least thirty," Tony replied, still grinning. "In fact, she's older than me."

"You're having an affair with an older woman?" Ziva looked astounded. "Wonders will never decease."

"It's cease, Ziva, and hey – I'm not that shallow!" Tony protested.

Ziva and McGee glanced at each other and then burst out laughing.

"Yeah, you really are, Tony," McGee said. "Come on – details."

"Hmmm." Tony steepled his fingers together and glanced over at Gibbs, who had given up any pretence at working and was sitting back in his chair, watching the proceedings with an amused gleam in his eye. That was like a challenge to Tony – and one he accepted with relish. "Well, she's hot," he told his eager audience. "Tall – almost as tall as me. Deep blue eyes – really deep, really blue. Fantastic figure." He shot a little smirk in Gibbs's direction and got a raised eyebrow in return. "And she has these really, really big – and I mean enormous, huge…" He made an extravagant shape in the air. "…hands," he finished with a sly wink. Ziva snorted, and McGee rolled his eyes. "And great legs. Long – very long, leading up to an extremely fine ass."

"Forget about her ass! Does she also have a personality, Tony?" Ziva demanded.

"Sure. I think you'd call it…explosive," Tony grinned, glancing at Gibbs mischievously out of the corner of his eye. "To be honest, she's kind of moody, but I forgive her because she's so incredibly hot."

"Moody?" McGee queried.

"Yeah – expects me to cater to her every whim and gets kind of grouchy if I don't jump to it every time she wants something."

Ziva frowned. "She does not sound very nice."

"She can be." Tony fingered the mark on his neck again. "She's surprising."

"Does she have a name, Tony?" McGee asked.

"Sure," Tony shrugged. "But I like to call her my little snugglebuns." He thought he heard a strangled sound coming from Gibbs's desk. "Or honeybreath. Or sweetiepie."

Ziva arched an eyebrow. "I am surprised you are still alive then," she commented. "If you were my boyfriend, you would be dead before your body hit the floor if you called me any of those things."

"And that, my dear Ziva, is why you and I must never date," Tony told her with a cheerful smile. "That and the fact that we are completely incompatible and have absolutely nothing in common."

Ziva glared at him. "I would rather date McGee than you!" she snapped, and then she turned on her heel and returned to her desk.

"Hey!" McGee said, and then he thought about it. "Was that a compliment or an insult?"

"I think she said she liked you," Tony told him. "You could be in with a chance there, Probie."

"You really think so?" McGee's eyes lit up.

Tony snorted. "Don't be an idiot, Probie. Besides…" He pulled McGee’s head down so that he could speak directly into his ear. "She's Mossad, Probie. They're like praying mantises – they have to kill each other after sex. It's in the Mossad rule book. Something about keeping them combat-ready at all times."

"Really?" McGee looked startled.

Tony gave him a look of disbelief. "No, not really, Probie! C'mon! How can I ever stop treating you like you were born yesterday when you keep behaving like you were born yesterday?"

McGee glared at him and slunk back off to his desk. Tony finished his sandwich and then got up and went to the men's room. He was about to use the urinals when he remembered the chastity device on his cock. He really didn’t want any nosy co-worker catching sight of it, so he went into a stall instead.

He finished up and was washing his hands when someone came in – and next thing he knew, he was being pulled around and then pushed into the stall he’d just vacated. The door was slammed behind him, and he found himself face to face with those very deep, very blue eyes he'd mentioned earlier.

"Snugglebuns?" Gibbs queried. "Honeybreath? *Sweetiepie*?"

"You wouldn't like me calling you any of those things?" Tony asked innocently. "You shoulda said! You never mentioned a rule against terms of endearments, and if it isn't a rule you can't punish me for it."

Gibbs grinned at him and pushed him back against the wall. "Newsflash, Tony; I can punish you for anything I like, any time I like. Now tell me, were you having fun back there?"

Tony gave a wide grin. "Oh yeah!"

"I thought so. So I'm gonna give you the chance to do it all over again."

Gibbs grinned dangerously, and then he pushed Tony's head over in the opposite direction to before, and next thing Tony knew Gibbs's mouth was clamped down hard on his neck again.

"Oh shit," he hissed, putting his hands on Gibbs's hips to steady himself.

Gibbs sucked for a little while, and Tony braced himself for what was coming next. Sure enough, Gibbs bit down, gently at first, and then he sank his teeth in with more force, making Tony squeak. His stupid cock seemed aroused by the whole thing and made a desperate and pointless bid for freedom while Gibbs marked him for the second time in one day.

It was hard to stay still and in place while his top bit him, but Tony managed it somehow. There was something about surrendering to Gibbs that was totally addictive. A dozen vampire movies flashed through his mind, but none of them were as darkly sexual and possessive as what Gibbs was doing to him right now. Then Gibbs released him. He examined the new mark on Tony's neck and then leaned in and licked it in a strangely intimate and affectionate gesture.

Gibbs drew back. "Twice in one day. You're a lucky boy, Tony."

"Yeah. Lucky. I knew there was a word for it," Tony groused.

"Come here."

Gibbs opened the stall door and pushed Tony over to the mirror. He stood behind Tony again and pulled his shirt open at the top so that both marks were fully visible. The new one was the mirror of the first – and they were on either side of his neck, the perfect matching pair. Tony liked the way his top was looking at them – as if he couldn't wait to strip Tony naked and bestow more marks on his bare skin. Tony shivered with arousal. Gibbs raised an eyebrow.

"Just thinking…you could mark me someplace else," Tony admitted.

"Yeah." Gibbs's right hand moved down and patted his ass. "I could."

“Boss – please tell me I don’t have to go back out there and face Ziva and McGee again,” Tony sighed. “They’re never gonna let this drop.”

“You finish all the reports I asked for?”

“Yes.”

“Then you don’t have to go back out there and face Ziva and McGee again.”

“I don’t?” Tony grinned at his top in the mirror.

“Hell no. You can spend the rest of the afternoon helping Abby out downstairs.”

“Thank you,” Tony said in a heartfelt tone.

“Of course it’ll cost you,” Gibbs said, a little smirk playing at the corners of his mouth. Tony glared at him.

“How much?” he asked warily.

Gibbs ran his fingertips lightly over the bite marks on Tony’s neck, with a territorial pride that made Tony shiver. “For depriving me of the sight of these all afternoon? Ten on the chalkboard.”

“Ten?” Tony glared at him some more. He hadn’t earned many so far today but his ass was still sore from yesterday, and he had been hoping to get by without adding to the day’s tally too much.

“Ten,” Gibbs repeated firmly. “Your choice, Tony.”

Gibbs pressed a quick kiss to the back of Tony's neck and left the room. Tony stared at himself in the mirror. It was very irritating being Gibbs’s sub, he decided, but he had to admit he was enjoying himself enormously, despite the difficulties. He trailed his fingers along the edge of one of the bite marks. Gibbs was right – they were too damn good to cover up.

In the end, he decided to take the extra swats and went down to Abby's lab for the rest of the afternoon. She took one look at his matching bite marks and gave him a massive smirk.

"Someone got lucky!"

"Yeah. Someone did." He winked at her happily.

She did a double take, staring at him intently.

"What?" he demanded.

"You – you look like I haven't seen you look in ages. You used to look this way after Gibbs head-slapped you. Hey – did Gibbs start head-slapping you again?"

"Kinda," Tony shrugged.

"Good," Abby said, turning back to her computer screen. "Because that whole weird not head-slapping you thing was freaking me out."

"Yeah. And me," Tony grinned.

Abby glanced at him with a big smile. "The bite marks suit you, Tony. It's a good look for you. Hey – did you hook up with a vampire?"

Tony sighed and rolled his eyes. "Not you too, Abs. No, I didn’t hook up with a vampire."

"But you're being topped by someone, right?" she asked. "Someone who knows what they're doing too."

"What?" Tony stared at her.

"Hey – I've played, I've tied guys up, I've topped. I know the signs!" Abby laughed. "I bet if you roll back your sleeves there are cuff marks on your wrists."

Tony peeked surreptitiously under his shirt sleeves. "Nope," he said. Then again, Gibbs hadn't actually tied him up yet.

"Okay – but you definitely have marks on your ass from being spanked," she said cheerfully.

Tony nearly choked. "I do not!" he protested too loudly and too fast, feeling his face flush. Maybe hanging out down here hadn't been such a good idea after all.

"Sure you do!" Abby laughed. "I'm so pleased for you, Tony! I knew that if you could just find the right top you'd be happy."

"What makes you so sure I'm a sub?" Tony asked. Abby laughed uproariously. Tony glared at her. She stopped laughing.

"Oh – sorry – you meant that seriously?"

"I did," he said stiffly.

"Uh. Okay. Well, just that you're about the subbiest guy I ever met, Tony. Not in the sense of being weak – uh-uh - but then the best subs are strong guys, like you. No, in the sense of you always seeming like a guy who needed to find the right kind of top to balance you out and make you feel like you have someone to belong to. When Gibbs was slapping you around it really helped you, but I noticed you've looked kind of like a lost puppy ever since he stopped."

"Well, now he's started again, so that's okay," Tony said swiftly. He glanced around the lab, trying to think of a way to change the subject. "So – can I help you with anything?" he asked eventually.

Abby rolled her eyes. "You hiding, Tony?"

"Yes," he replied bluntly. "It's Ziva and McGee – I don't want them to see…" He pointed his finger in the direction of his marked neck.

"You could just do up your shirt," Abby commented helpfully.

Tony made a face. "No. I really couldn't," he sighed.

Abby stared at him some more. "Oh!" she said eventually. "Your top is totally evil! I like it! Okay – you can help me with this. But don't touch anything unless I say so."

Tony gave her a grateful smile. He’d just earned himself another ten swats with whatever devilish implement Gibbs intended to use on his poor ass this evening, but he thought it was worth it if it meant avoiding McGee and Ziva for the rest of the day.
