In honor of KittyKat757's request, I am doing a sequel to the Neko chapter. It's a little long, I know, but it just kind of happened.

Enjoy!

"Don't."

Charlie gave Dean an innocent look, ears as red as her hair pricked forward intently. "Don't what?" she asked brightly.

"Say I told you so."

"I wasn't going to." Her wagging tail told a different story, but Castiel decided to intervene before they could get too far into their bickering. He'd never understand a Canine's penchant for it, even if it was done with a sense of sibling fondness.

"Come on, it's late," he urged, standing and tugging Dean up from his seat. "We have an early flight, remember?"

"Go on. I've got the red-eye. My lady misses me when I'm away."

"Why don't you just bring Fay with you?"

"She does the LARPing with me. My going to Comic Cons gives her some Fay time. It's a win-win."

Ah. Castiel filed that away for later pondering. While he'd enjoyed himself this was more Dean's thing than his. Perhaps he would simply send his mate next time.

They said their goodbyes and left the hotel's restaurant, taking an elevator up to their room. It really wasn't too late, but he was tired. They'd spent the last several days getting up early so they could get to an event or lecture or autograph signing on time. Even then the lines had seemed to have taken far too long. While Castiel didn't regret his experience, he'd decided this was something he'd let Dean have in the future. The Canine had been able to let loose and geek out at every turn, feigning calm as he got Dr. Sexy's autograph, making Castiel take his and Charlie's picture inside a Tardis replica, geeking out over highly detailed cosplay. There was even a booth that sold the more elusive editions of Busty Asian Beauties, where Castiel had obtained his Christmas present.

As they finally reached their hotel room, closing and locking the door, Dean dropped into one of the chairs. He looked tired, but a wide grin was on his face. "That was awesome."

Castiel frowned slightly, shrugging off his trench coat and perching on the foot of their bed to pry shoes off his sore feet. "The meal was good, but I didn't think- "

"No, this whole thing, Cas. You set all this up and it's been awesome. Well, except for the plane ride, but I honestly don't care I'll be getting on a flying deathtrap tomorrow."

This alone was a significant statement from his mate. Considering he'd white-knuckled his way through their flights from Sioux Falls to LAX by way of Denver, when he wasn't actually on the plane he'd still been excited. In the time leading up to the flight and as soon as he could scramble off the plane. Even if they'd been able to afford first class, he knew it wouldn't have changed anything.

"I was hoping you would enjoy it. I didn't realize how much, but that's hardly a bad thing."

"Do you have any idea how high you set the bar? I can't top this."

"I don't want you to top it." Castiel leaned back on his elbows, wiggling his toes with a low groan.

"I'm still gonna try."

"Just don't try too soon. I don't think our bank account would appreciate a hurried attempt."

Dean chuckled, tail wagging slowly through the chair's gap. "Fair enough. You, uh, didn't poke through my checked bag, did you?"

Castiel gave him an odd look. After some debate they'd decided it was simpler to each take their own bag rather than cram everything into one large one. There was also more space for souvenirs this way. Apparently Dean had taken advantage of it in another way.

"No. I haven't had a need. Why?"

"You wanna get a shower? Maybe a bath?"

"I was going to get a shower anyway."

"Awesome. Why don't you go do that?"

The Feline gave his mate an odd look, but lurched off the bed anyway. He liked being clean, especially after a long day. He pulled a clean pair of underwear and his night clothes from his suitcase, trudging into the bathroom. While he was at it he shaved and brushed his teeth once he'd stepped out of the steamy shower.

Ready to spend what remained of his early night relaxing, Castiel stepped out of the steamy bathroom. He meant to set his dirty clothes in the suitcase, but he didn't get that far. Now he stared, head tilting, ears pricked forward curiously, at what had become of their small hotel room. The lamps had been turned on, the overhead light turned off, the bed turned down. The Feline caught sight of several items from their bedroom stash, things he hadn't known Dean had brought, right before his mate stepped into his line of sight.

"Feeling better?"

"Yes, but what is this?"

"A surprise."

Castiel glanced at the bed, then down at himself. He hadn't packed for this sort of thing. At current he was wearing old boxers, a pair of well worn sweatpants, and a ratty t-shirt from his own college days. "I, um...didn't anticipate this."

A crooked finger tipped his chin upward, until he met his mate's gaze again. "You weren't supposed to. I don't care what you're wearing. It all gets in the way anyhow. What color are you?"

"Green," breathed the Feline, excitement pushing away the weariness.

Dean pecked his lips tenderly, then drew Castiel towards their bed.

The Omega let himself be guided over, not putting up a fuss as Dean had him lay down on his back atop the sheets, his shirt peeled over his head and set aside. The Canine braced a knee on the bed, leaning over to use a pair of padded cuffs to bind his left wrist to the headboard. Then he went around, doing the same for his right side. Satisfied, fingers gripped the Omega's chin, turning his head and holding him steady for another kiss.

"Gonna have to wait a few minutes, Angel. Okay?"

"Okay."

A strip of black silk was laid over his eyes, tied gently behind his head. With one more, lingering kiss Dean slipped away. He went into the bathroom, leaving the door cracked by the sound of it. Technically leaving someone bound in this fashion alone wasn't considered safe, but Dean hadn't shut the door and Castiel knew which cuffs he'd brought. This particular set had safety releases he could tug open with ease. If the need arose, he could free himself. That wasn't what worried him.

Dean, unlike many of the Canine's he'd known over the years, enjoyed being clean as much as Castiel himself did. Meaning if he was in the mood he could take very long showers. The Omega tugged uneasily at the cuffs as he heard the shower turn on, ears flicking forward then back then forward again, tail twitching on the bed. He tried to distract himself, consider other things, but his mind always came back to the here and now. As mad as it drove him, the anticipation, the waiting, always got him tensed up. Made whatever Dean eventually did do to him seem more heightened, made the eventual climax more intense.

Eventually Castiel gave up and began running through a mental list of everything they had at home. He removed things that wouldn't fit in a suitcase first, then the things that might get flagged or removed. This soon got difficult, as he wasn't sure if candles would be allowed or if they'd melt in transport. Would a whip or crop be confiscated? Oh gods what would happen if Dean had packed any of their vibrators or insertion toys?

Castiel almost moaned in relief as the door swung wide again, ears pricked and straining to hear his mate. Dean was barefoot and going out of his way to move quietly, but the Omega was just able to make out his movements. By his suitcase, then coming around the bed. He heard his mate shifting a few things around, but couldn't make out enough to tell exactly what those things were. Worse, he'd let himself get too worked up. His chest was rising and falling too fast to be considered calm, roaring blood and his own breath filling his ears.

When fingers finally brushed his jaw the Omega gave a start, grimacing when he heard his mate chuckle. "You're cute when you're all excited," the Canine hummed, thumb brushing his lips. "All keyed up and responsive."

Castiel was never sure what to say to such things, so he kept his peace. The fingers left his face, moving to his bare chest. They stroked and plucked and tugged at his nipples, getting them hard. They were also a bit sensitive when clamps capped in rubber slowly closed down over them, but he managed to maintain a grip on control this time. He didn't twitch, his breath didn't hitch, even as the Alpha pulled the connecting chain taunt. Though he did shiver slightly as the inside of one of his ears was nuzzled with smiling lips

"TSA's a bitch, but I slipped enough through for us to have some fun. Gonna make you cum for me, Angel."

The Feline was both thrilled and frightened by the prospect, though he tried not to show as much. Frightened in a good way, not unlike what he felt when he knew his mate was about to use a whip or paddle on him. It also crossed his mind that if Dean pushed him he wouldn't be able to keep quiet, and he didn't fancy their neighbors hearing him beg for release or cry out in ecstasy.

What he recognized as a feather brushed his side, making him twitch. He managed to contain most of his movements, if barely, as it trailed over his body. Lightly tracing his fingers then drifting up the length of his arm, sending chills through him, brushing his chest and stomach. His head tilted back on the pillows when it came up to trace a line down the center of his face, brushing down his nose and over his lips.

The shivers had migrated south in a heated form when his mate slid off him, setting aside the feather to pull off his pants. Digits hooked under the waistband of both his pants and underwear, peeling them from his legs. He half expected the Canine to start with the feather again. He was mistaken. As soon as Dean had settled again he heard a lube bottle pop open. Unfortunately he doubted this would be a true indication of what he was in for. While different sounds of different bottles would be significant at home, he was guessing Dean had had to put lube in travel bottles for this, which all sounded the same to him.

It was a long minute before a hand came under his cock, cupping it in a warm palm. He'd stirred a little when his mate had used the feather, but he tended to get wet before he got hard. He felt his hole twitch, his slick production jumping up a notch as it hit home just what his Alpha was about to do to him, his breath catching.

A thumb lightly brushed his slit, a warning before something cold and hard began to slowly press inward. Castiel's head fell back, though he made every effort to hold as still as possible for all his chest began to rise and fall rapidly. Dean pressed the urethral sound in a very slow, very continuous movement, letting the slightly curved length of sterilized metal slip gradually deeper and deeper inside his cock.

What had started as an experiment had become something of a personal favorite. Considering it had been Dean's idea, brought up during his search to find more exotic ways to make his Omega wail in pleasure, it had become something of a treat for both of them. They'd tinkered and practiced with it, enough to figure out what was too big, what was uncomfortable, and what made the Feline shed tears of ecstasy. The Omega's personal favorite was a slightly curved rod a size below the one he found painfully uncomfortable. Covered heavily in the special lube they bought for just this use, of course.

When the movement finally stopped, a hand ran slowly up his thigh, stroking his hip. Castiel gave in, whimpering as his tail lashed up and down on the bed, the only body part he allowed to move wildly at this point. He gasped outright when a titanium cage of thin bars slid over his member, settling into place, the ring at its end tightened to fit snuggly at the base of his cock. He heard, and felt, something screw into place at the sound's end. The ball that would attach it to the cage, keeping it in place.

"Feel good, Angel?" the Alpha rasped, tone husky with lust. He tugged lightly at the chain between his nipple clamps, pressing a kiss to his jaw.

"Yes-yes mate," the Feline whimpered, shoulders writhing on the bed. His legs shifted over the sheets as much as they were able, confirming Dean's position between his knees.

"Say ah."

Obediently Castiel's mouth fell open. A bit settled between his teeth, an alternative to the ball gag, but Dean didn't bother strapping it into place. Instead he petted the Omega's hair, stroking his twitching ears.

"Don't matter if it feels good," the Canine rasped in his ear. "Now be a good little bitch and do as I say."

Castiel nodded rapidly, his hole twitching around empty air, his cock hardening in its cage. It was one of the oddest, but most tantalizing sensations he'd ever endured, getting hard with a sound in his cock. Naturally his mate was aware of this. He was also very aware of what could make him hard in a short period of time.

Leather straps were secured to his ankles, and briefly Castiel wondered just how Dean had managed to fit so many things in his suitcase. It hadn't seemed that full, yet it seemed his mate had smuggled at least half a dozen fun things on their trip. Though considering this adjustable spreader bar was the largest yet...

The Omega revised that last observation as his legs were lifted at a ninety degree angle, knees bent towards his chest. His crotch's center of gravity shifted, wringing a hitching whine from his throat. It was followed by a squeak when he felt something very familiar trace up the back of one thigh and down the other. It was a warning that had him tensed up just in time for the first blow on his ass with the crop. The one with a broad head, meant to sting, and boy did it.

"Wonder how much it'll take to make tomorrow...uncomfortable," the Alpha mused aloud.

Even if he'd been allowed to answer Castiel didn't know if he could have. He was at his limit. Among their multitude of experiments in the bedroom had been just how much he could take at once. At the moment the bondage, blindfold, gag, clamps, sound, and now the crop made for six. Depending on the stimulus he could handle more, but the urethral sound always counted for double. If simply left this way without the crop for long enough he could cum with just a touch. With the crop...his head was starting to swim. Not much, but enough to boarder on his yellow zone.

Strike after strike was laid down over his ass, an irregular pattern between cheeks, plus the occasional sting on his thighs. His chest heaved, his entrance dripping slick, his cock throbbing inside its already tantalizing confines. If he didn't have the bit to sink his teeth into, he really would be making noise. At least Dean had given him that small mercy, knowing he wouldn't like disturbing their neighbors.

Castiel lost count somewhere around twenty, fingers starting to scrabble at his bonds, head jerking back and forth, chest heaving in whimpering pants, his eyes watering beneath the blindfold. He slumped in the Alpha's hold when the crop finally ceased its abuse, instead reaching around to lightly pat his belly after tugging out the bit. He was aware of Dean talking, but he didn't quite catch the question.

The crop stilled, and in a louder voice the Canine asked, "Cas, what color are you?"

"Mmm...yell...no, green." His slurring statement was followed by a yelp as a hand smacked his ass.

"You really wanna go through thirty spankings right now? You know better than to lie to me, Angel. I'm gonna ask you a third time, what color are you?"

A pitiful whimper preceded his answer. "Yellow, Alpha. Good yellow."

He twitched when a hand brushed his temple, but relaxed when it only stroked his face. "Thank you. Think you can hold out a little longer if the crop goes away?"

"Yes, mate."

His legs were lowered back down to the bed, the spreader bar removed and set aside along with the crop. The bed shifted as the Canine crawled over his body, knees bracing on either side of his chest just below his arms. A hand tangled in his hair, right between his ears.

"Open your mouth," the Alpha growled, the husky tone of lust back in full force.

This time Castiel opened his mouth wide, knowing what his mate wanted of him. A cock that was no doubt painfully hard and leaking precum slid passed his lips, thrusting all the way to the back of his mouth. He relaxed his throat, offering no resistance as his mate began to fuck his mouth, gasping air when he could. He heard the bed frame creak, this time as the Canine gripped it tight with his free hand, a growl of pleasure rumbling in his throat. He heard it give an extra bit of protest with each thrust, particularly the deep ones that made him glad he had virtually no gag reflex.

He knew his mate was close when, after being allowed a few seconds to breathe, the Canine's throbbing cock was shoved down his throat. His head was tilted back by the hand still in his hair, his eyes watering as even more droll rolled down his jaw. Blow jobs were so messy, especially when he was bound, as some comedic deity had seen fit to substitute his gag reflex with abundant saliva production. But he liked the sense of being used, a bitch to be fucked as his mate saw fit, and Dean obviously enjoyed them.

Fingers left his hair in favor of massaging the Alpha's own cock through his throat, toeing the line between pleasure and pain. When Dean dragged his cock out the Feline was allowed only a few seconds to cough and wheeze, right before the process was repeated. Only this time, as tears overflowed from the Omega's eyes, they also rolled back behind his blindfold as he felt hot cum spurt from a pulsing member.

Just when he was starting to see black spots from oxygen deprivation, Dean withdrew his spent cock, breath rasping in raged pants. Castiel swallowed rapidly, coughing and retching as he caught his breath. Ignoring the mess he'd become, fingers gripped his chin and a mouth dominated his own, robbing what little breath he'd managed to regain.

When at last he was allowed to gasp freely for air, he felt gentle fingers trailing down his thighs, a wagging tail brushing his calves.

"So fucking good for me, Angel." It was as much growl as not, making the Feline whimper and shiver under his touch. "You ready to cum for me?"

Castiel couldn't nod fast enough. "Yes, please mate. Please let me cum, please make me cum."

His babbling was cut off in a soft, choked cry as one nipple clamp was slowly removed, then the other. Numbed flesh suddenly became hypersensitive, blood rushing back with a surge of pain quickly overwhelmed by a hot throbbing. His chest was still heaving when the screw at the sound's end was unwound, the cage eased off his aching cock. At first the sound began to follow, but when only the tip remained inside him it was pushed back in again. His back arched, mouth falling open in a blatant cry of ecstasy.

Smiling lips pressed to his lower belly, a hand pressing his chest back down to the bed. "Shh, steady Angel. Don't move. I'm gonna do that again, and if you're good and still for me I'll finish you. Okay?"

"Yes Alpha," Castiel gasped. His hands fumbled, searching desperately for something to hang onto.

Again the sound was sluggishly withdrawn, and Castiel barely managed to restrain himself. It was lost in a flash of white beneath his lids, his body a hair's breadth away from a disobedient climax, as the sound was once more pushed back within his member. Oh gods, as much as it made him see stars of pleasure this much movement made him so sensitive pain was never far behind.

"Yes what?" the Canine murmured, pressing a kiss just below his navel.

"Yes master," Castiel sobbed.

Lips lingering near his hipbone turned back up into a smile. "Atta boy. One more."

Castiel managed, barely. He was a tearful, whimpering mess when the sound was finally withdrawn in full, panting and desperate. He cried out when two fingers slid inside his gushing entrance, wishing for the bit gag again as they stroked his inner walls.

"Now be good, Angel. Cum for me."

Even as the order was given those two fingers began massaging his prostate. They kept at it, Dean's free arm holding his hips to the bed as the Feline outright screamed in ecstasy, his entire body convulsing and bucking as much as the restraints would allow. It had been a long time since Dean had toyed with him so long and so hard, since he'd climaxed with such intensity.

When at last he lay limp on the bed those fingers withdrew from his prostate, which was now just as oversensitive as just about everything else. He lay limp and unmoving as his bonds were removed, along with his blindfold. He was vaguely aware of his mate moving around, cleaning things and stowing them once more. If he'd been tired before he was now as drained as it was possible to be, a purr thrumming in his throat.

The Feline was almost asleep when he was pulled into an upright position, stirring unwillingly.

"Come on, Cas. One quick trip then you can sleep."

Too out of it to disobey, Castiel swung his legs sluggishly over the bed's edge and lurched upright. Dean kept an arm around his waist, draping one of the Omega's over his shoulders, keeping him steady as they walked to the bathroom. His legs were too unsteady for him to stand, so the Canine lowered him to sit on the toilet. The purring was cut off as he reluctantly let his bladder go, not enjoying the sting of urine on sensitive skin. He turned, burying his face in Dean's shoulder as his mate petted his hair soothingly. Depending on the day the endurable downside was part of the play, but right now it was something to get over with.

Dean took the liberty of cleaning him up a little before helping him back into the bed. As soon as they were both under the covers, the lights turned off, Castiel sluggishly moved to cuddle against his Alpha's side. Arms wrapped around him, and he buried his face in Dean's shoulder as he sank into an exhausted sleep, a purr thrumming in his throat once more.
