Jennifer was hanging up her coat in the hall closet when it happened. One large paw snaked around her body from behind, holding her tight, while another clamped around her muzzle holding it closed and stifling her yelp of surprise. The petite collie girl shivered as a low voice growled in her ear.

"You're late. And you left the back door unlocked so I let myself in. Lucky, that. I could have been sitting around in the snow freezing my tail off wondering where the hell you were. You didn't call, you didn't text. But you should have locked the door. Aren't you lucky it was me that let myself in and not somebody else?"

The paw relaxed around her muzzle and she drew a deep breath before replying quietly.

"Yes. Lucky twice. That it was you and that it was open so you could come in. I'm sorry, the store was packed with the sales on and everything took so much long..." The paw closed around her muzzle again.

"What have I told you about excuses? Next time stop at the apology. You know you're wasting time trying to excuse yourself from not contacting me anyway."

As soon as the paw came away from her muzzle the second time, Jennifer gasped "I'm sorry, Marcus. I should have called you. And I should have locked the door."

"Better. I think you need a few reminders, so I'm giving you fair warning that should you choose to play, I'm going to be a stickler for the rules. All the little rules including the ones I sometimes relax because of our agreement. Now go put those things away." Abruptly she was released and heard soft footsteps receding into the living room of her small apartment. 

Bending to pick up the three bags on the floor by her feet, Jennifer hurried through her kitchen and bedroom, quickly distributing the bags contents through cupboards, draws and closets. She stood in front of her dressing table mirror, staring herself in the eyes. She'd never seen herself as particularly beautiful, maybe attractive in the sort of girl next door way but never beautiful. She had pale blue eyes, shoulder length blonde hair that she'd never been bothered to do more with than tie it back in a pony-tail and nothing much to speak of in the way of curves, being a very trimly built young woman. As she watched herself, it was like the girl in the mirror was undressing her rather than she doing it herself as she unbuttoned her blouse and dropped it over the back of the chair, exposing the modest B-cup breasts topped with deep pink nipples, firm enough that she never needed to wear a bra, which suited her just fine because she hated them.

She'd left her snow-boots at the door so there was nothing in the way as she unbuckled her jeans and unzipped them, sliding pants and panties smoothly over her slender hips and bending to make sure that she collected her socks on the way. Catching sight of herself again in the mirror, she smiled. 'Yeah' she thought to herself, 'Whatever else may be lacking, I've got nice legs.' 

Looking down from the mirror, she picked up and opened a slim, polished mahogany box from the dresser and smiled slowly, thinking to herself 'Marcus calls me beautiful all the time. So long as he thinks so it doesn't matter if he's wrong.' Her other hand strayed to the drawer where she kept her underwear but then froze. 'No,' she thought. 'Not this time. He said all the little rules didnt he? So I do this in front of him, naked.' She closed the lid on the box and refastened its latch.

Carrying the polished wooden box, she slipped out of her bedroom and padded into the living room. She kept her eyes down but still noted the throw cushion seemingly casually discarded in front of the sofa, in front of a pair of large hindpaws belonging to the person sitting there. Gracefully, she sank to her knees on that cushion, feeling a little tingle between her thighs as she wondered 'What has he in store for me this time?' She straightened her back, demurely flipped her tail into her lap and only then looked up at the muscular grey wolf in the sofa, immaculate in his shirt and slacks, his grey eyes pale against his brindled fur watching her as she extended her paws, offering him the wooden box, watching his eyes watching her as he reached forward and lifted it out of her hands. 

"Before I open this, tell me the rule about what's inside it."

"That once I put it on, it stays on until you release me from it."

"And while you wear it?"

"I am yours to use as you wish."

Smiling, he opened the box and reached into it, laying a polished leather collar across his paw. 

"So, my beautiful collie-lass. If it's truly what you want, that and all that comes with it, wear it for me."

He extended his paw with the collar draped over it. With an eagerness she could almost not believe, no matter how many times she felt it, she lifted it from his paw and fastened it around her neck. Turning on the cushion, to face away from her lover, she lowered her muzzle to look at her knees then reached behind herself to lift her hair away from the collar and give him an unrestricted view of the buckle. She felt his paws on it and then heard the soft click of the lock, its small weight let fall to  dangle against her neck.

"How may I serve you, Marcus?"

"Turn to face me, Jennifer." He stood up as she obeyed. "Now you may remove my clothing and while you are doing so, tell me the real reason you were late."

"I just lost track of time. I was late leaving in the first place..." As she spoke she was standing and beginning to unbutton his shirt. His paws steadied her as she rose to her feet. "... It took me longer to tidy and clean the place than I expected, but I knew you were coming so I had to finish it."

"If you had known I intended to be here as your vanilla lover tonight, would that have mattered so much?" The last button came undone on his shirt front and he extended his paws to her so she could unbutton his cuffs.

"Not so much, no, but I don't like you seeing the place in a mess even when you do come here that way. Besides, I didn't know. I really didn't want you to see it like that if you were going to be like this."

He smiled as her delicate paws brushed the shirt off his shoulders, dropping his arms so it could fall. As it fell she caught it and laid it over the arm of the sofa rather than letting it crumple on the floor.

"Like what?"

"As a dominant alpha, requiring me to submit." Back on her knees, she worked on first his belt, then the button of his pants.

"But you chose that. You could have put your shopping away, walked down here in your usual comfortable clothes and just snuggled up with me on the couch. You know I'd have respected that and not insisted on you wearing the collar. " That drew a giggle as she carefully drew off his pants.

"Marcus, with the way you greeted me today, how could I not choose to play and submit to you?"

"But it was still your choice. I want you to confirm that for me."

Jennifer froze. He'd never offered that before, once she chose to play, once she wore the collar, it was decided, she would submit to her dominant lover and refuse him nothing until he chose to hand her the key to release it. Her breath caught and she felt herself warm a little more as she found her voice to answer him.

"Yes, Marcus. This is exactly what I want."

"You remember how I react to you lieing to me, don't you? You have to be really sure tonight."

She did remember. She remembered the one time she'd tried to fake an orgasm for him. The anger in his eyes, the way he'd immediately stopped and bent her over his knee and soundly spanked her, only to recognize that she was enjoying it and move on. Move on to binding her over a chair and bringing out the cane.

The cane.

The memory wasn't entirely unpleasant. Of course she remembered how it bit into her skin as he held her tail firmly out of his way, how the pain flared throughout her body from each stroke, how she had screamed and slobbered into the gag tied tightly into her muzzle, how tentatively touching her rear after it was over made her wince as her fingertips ran over each raised and swollen welt he'd left, how the dull ache reminded her of the punishment whenever she bent over or sat down for three days afterwards. But she also remembered how he'd unbound her and gathered her into his arms when he was done, whispered gently into her ear 'You are forgiven' and softly, tenderly made love to her, stroking and teasing her to such heights of pleasure. She was certain. She wasn't going to lie to him tonight.

"Marcus, I am completely certain."

But why was he so insistent on the confirmation that she freely chose to submit tonight? What was different about this night compared to all the others she had worn her collar and let herself fall, confident her lover would be there to catch her?

"Very well."

She looked up from her knees to gaze at the now-naked wolf standing before her and smiled, her eyes soft as she gazed up at the man who had been her lover for over a year. She felt warm and safe, the feel of the collar around her slender neck and the slight weight of the lock hanging from it like a perpetual embrace, even though he wasn't touching her at all. She'd loved it the first time she'd felt it, even though she had been nervous about asking him to explore her kinkier side. It wasn't like there was any serious committment involved anyway, they were "friends with benefits" and if those benefits had become steadily kinkier over time that was no ones business but their own.

She stopped wondering about why tonight was different, drawing a deep breath and letting herself relax into the welcoming softness of ceasing to be her own creature, giving herself completely to a lover she knew would care for her and attend to both her pleasure and pain as they were required, freeing her to concentrate solely on his enjoyment of their time together, even as he bound her, releasing her to discard all the pretended limitations that people outside this place put upon her. It didn't matter why tonight was different. She knew she was about to find out.

------------------------------------

"Please! I need to cum!"

"No."

In spite of the sensations coursing through her, Jennifer felt her body back off from the impending peak, only for her sensitivity to ramp up yet another notch, desperately needing release but unable to find it. Her eyes were glazed, her tongue lolling from her muzzle as she panted, a small pool of drool collecting on the pillow beneath her head and soaking into the short fur on the side of her face.

She was totally immobile, wrists and ankles pulling against the cuffs secured to a metal frame. She'd watched as right after she had put on her collar and undressed Marcus, he'd pulled the various parts of it out of a duffel bag and fitted them together. She couldn't even buck her hips because he'd braided a long ribbon into her hair and then pulled the long ends of the ribbon tight to tie it to her tail, forcing her to arch her back and present herself.

That, on its own, was enough for her body to betray her, it knew what was coming and uncomfortable as the position was, she felt the arousal, the growing need. At the back of her mind was the question 'Is it going to be pleasure or pain this time?' although she didn't much care. He was good at blurring the line between them. She could feel the damp warmth growing on the lower lips she was forced to so brazenly display.

He'd started by gently caressing her, fingertips drifting down her back, over her rump. across her thighs, drifting close to but never touching her warming feminine center. Gently stroking across her breasts, but never touching her nipples. He didn't say a word, only touched her - incredibly softly and gently for such large paws - quietly encouraging her body as it warmed and prepared itself to be loved, softly fanning the beginning flames of her desire and need but not building them into a blaze - at least not at first.

Then he leaned down, his breath stirring the fur on her ears and whispered softly "I'm going to test your limits tonight. Do you remember your safeword?"

"Yes." Then she yelped softly as he lightly nipped her ear.

"So? Prove it. What is it?"

"Popsicle. It's popsicle."

"And you promise to use it if you have to, right?"

"Yes, I promise."

A gasp turned into a moan as she felt his teeth taking a firm grip of her scruff. Although she couldn't she tried to raise her rump higher to give him easier access, but then the soft bite was gone.

"Oh no, you thought I'd mount you and mate you right now? That would hardly be testing your limits now, would it?" As he continued, she whimpered quietly "Although, it does please me that you are so eager. That will make the next part much more enjoyable."

His footsteps were quiet on the thick carpet as he stepped around her and into her view for the first time since she'd been tied down. Her eyes locked on his ass and waving tail as he stepped over to the small closet where she kept her music gear. Reaching in, he brought out one of her mic stands, adjusting it to its lowest height as he unfolded its legs. Carefully he unscrewed the standard mic clip from the end of the boom and replaced it with something similar in appearance but much larger. Way too large for any mic she'd ever seen. Then she saw what he was fitting into it. It did sort of look like a mic, in a way. She'd seen them before but only on internet videos. This was her first in-person view of a wand vibe.

Now it was pulsing insistently between her legs, its electrical endurance giving her no respite, no mercy. She shuddered again, desperately reaching for the peak she was being denied.

It had taken less than five minutes before she had first asked for permission to cum. He'd smiled.

"Way too soon. Let me take your mind off it."

He'd held up a pair of clover clamps in front of her suddenly-wide eyes for a second, before reaching under her body and firmly attaching them to her nipples, first left and then right, each one making her breath hitch in her throat and focusing her attention entirely on their tight clasp on her sensitive flesh rather than the intense waves of pleasure radiating from lower down her body.

"Now that I have your attention... You remember the rules about cumming don't you?"

"If you're in me, any way, I can. Otherwise I have to ask first."

"Very good. I advise you not to even dream of breaking that rule tonight."

A few minutes later, she had thought she was being clever. After all, all guys were complete suckers for blow jobs, right?

"Please may I suck you?" He laughed quietly before replying.

"So that you have permission to cum because I'm in your mouth? No. Not yet. Let me help your discipline a bit."

A loud and high pitched yip resounded off the walls as he pulled gently on the chain between the nipple clamps, the tension causing them to momentarily bite harder.

"All properly focused again?"

She tried to nod and catch her breath, only to yip again as she pulled her own tail thanks to the ribbon binding it to her hair. His eyebrows went up and she knew he wated her to reply but it was only when he started reaching for the chain again that she found her voice.

"Yes! I'm properly focused again!"

"Good girl. I'm glad I don't have to put a pair of these anywhere a little more sensitive at this stage in our relationship."

That made her gasp again, but at the same time refocused her attention on the sensations between her thighs. She could almost imagine how it would feel to have that pressure on her nipples transferred to swollen lower lips and while she didn't want that, she moaned quietly as she realized that she didn't exactly not want it either. 

"Now, remember Jennifer. Do. Not. Cum." And then he'd stepped behind her and switched the vibe to its highest setting,

She had quickly lost track of time after that. Was it three or four times she had desperately begged to be allowed release? Every time she was answered with the same single syllable. Screw this! She needed it and she was going to take it anyway! Instead of trying to writhe away from the device tormenting her she reversed her efforts and pushed back into it as hard as her limited mobility allowed. The sensations quickly built to an almost unbearable level. Pain or pleasure, she couldn't tell. All she knew was wanting more, needing that last little bit to push her over the edge.

It didn't happen. She could see him sitting there, watching her try to disobey him and fail. He got to his feet and stepped behind her again. Would he finally take her, finally give her the release she craved? 

No. The vibrations between her quivering thighs abruptly ceased and the wand was carefully moved aside. She would have screamed as the nipple clamps were abruptly removed, but she didn't have the breath. She tensed, hoping to feel her lover pressing into her, but instead she felt a gentle touch on her ankles as the cuffs there were unfastened, followed by the same at her wrists and a soft tug on both her hair and tail as the ribbon connecting them was sliced cleanly through. She tried to keep her position, desperately wanting to feel him claim her but again her body betrayed her, her arms and legs collapsing under her and her body slumping to the ground.

No. Not to the ground. Into a pair of strong arms. She was lifted and settled against a body she knew. Oh, how she knew it. She knew its scent, she knew the feel of its fur against hers, the feel of its arms around her. She was part of this body as much as his arms or legs.. She could relax here. It didn't matter that she hadn't found release. She was safe, she was in her lovers arms and it was exactly where she wanted to be.

"Jennifer."

She drew a shaky breath, raising her muzzle from where it rested against his chest to look into his eyes.

"Yes?"

"Cum for me."

That was all it took. All the sensations from the last who-knows-how-long came roaring back and she arched like she'd been stuck with a cattle prod. Her eyes closed and her head flung back, she lost herself in the feeling that gripped her between the legs and squeezed her entire being, a tiny fraction of her being regretting that there was nothing inside her to respond to her pleasure. Thrashing in his arms she let out one loud sobbing howl before collapsing bonelessly against him. It was a long time before she was able to speak.

"Th.. Thank you...."

"I love you, Jennifer."

"I love you, Marcus. But you weren't kidding about testing my limits were you? That was fucking intense."

"Was it too intense? You could have..." She silenced him with a kiss.

"No, it was wonderful, you silly wolf. You take such good care of me. I thought wolves were supposed to be ravening predators or something?"

"Well, I might be. Got any ideas how to soothe the predatory instincts that having a beautiful naked collie writhing in my arms is likely to have aroused?"

Still drifting in the afterglow of the most intense orgasm of her life and feeling the evidence of those "predatory instincts" poking her in the back, Jennifer smiled.

"Mhmm... "

Scootching out of his lap, she lowered her muzzle down to him, licking and tasting his entire length before enthusiastically engulfing him in her maw. She was reaching her paw towards his balls when her wrists were both caught in his larger paws,

"No paws. Not on me, not on you. Clasp them behind your back and don't let go. All I want is your pretty muzzle."

"Mmmmmm....."

Bobbing her head up and down as her lovers hips twitched, Jennifer felt herself getting warm and wet again. She wanted to reach between her legs and try to bring herself off at the same time as she made him unload into her muzzle, but that was forbidden to her. Without the use of at least one paw this was going to take a few minutes anyway. She relaxed and concentrated on enjoying pleasing her mate. Hopefully her earlier display had turned him on enough that he wouldn't outlast her jaw muscles.

She felt him twitch within her mouth as her lips kissed the top of his slowly swelling knot. It didn't feel any larger than the ball gag he used on her sometimes, she could handle this. This was it, she'd got this. On the next slow stroke down his length, she gaped slightly, letting her lips slide over his knot and lock against the base, Marcus deeper in her throat than he'd ever been before.

It pushed him over the edge. Her mouth was flooded with his musky salty taste. She'd tasted it before, but this time was different. 

As he emptied his balls into her muzzle she felt her nethers clench like a closing fist. She moaned with her lips still clamped around the base of his knot as her second orgasm of the evening washed over her. While falling through the pleasure some corner of her mind had time to wonder how she got to cum even though nothing had touched her at all.

--------------------------------------

Long minutes later they were still naked, snuggling in front of the fire.

"Do you recall about 11 months ago you made a rather foolish wager with me? Can you remember?"

Her breath caught in her throat, because suddenly she did remember.

"You told me that you could train me, could condition me, so thoroughly that when you told me not to cum, I couldn't, that when you told me to I wouldn't be able to help it, that you could train me to cum just from the taste of you in my mouth"

"Yes. And what was your reply?"

"I told you that you were full of it, that it wasn't going to happen."

"Correct. We made a bet. My stake was that if I couldn't do it within two years that I'd never seek more out of this relationship than the 'friends with kinky benefits' that you said you wanted. What was yours?"

She reached up and touched her collar. "That if you succeeded, this would never come off and I would be completely yours forever."

He placed a small key on the ground in front of her as he had so many times before. Every time he'd done it in the past, she'd picked it up and used it to unlock and remove her collar. Trembling, Jennifer reached for it and stared at it for a minute before bracing it against the side of the hearthstone and leaning on it with all her weight until it bent, then snapped.

"Get dressed and pack your things. We're leaving."

"Yes, Master."
