Sam arrived home from work an hour before his girlfriend, as he did every day. Just as he had been hoping all day there was a package waiting for him on the front door.
A wicked smile crossed Sam's face. Excitedly he grabbed the small white box and brought it inside. Once he was away from prying eyes he tore into the package.
Inside was a fairly ordinary looking dog collar. Sam took it out and turned it around, examining it from various angles. The inside was covered in tiny metal contact points, and there was a little bulge near the collar's ring. Cute. At least they made the effort.
The collar was a very special BDSM toy: allegedly it would limit the behaviors of the wearer to those of a dog. Sam didn't really believe any of that, he figured the claims were on the same level as the ads for X-Ray Specs in the back page of old comic books, but the idea turned him on so much he had to order it.
He couldn't wait to surprise Allison with it. They would have fun roleplaying that the collar really worked. This was exactly the sort of scenario Allison liked.
Sam's intention was to wait for Allison so he could make a big dramatic show of the collar working, but first he just wanted to try it on and make sure it fit. It would be a pretty big letdown if he hyped this thing up and then he couldn't actually wear it. He didn't need another repeat of the Great Catsuit Disappointment.
Sam wrapped the collar around his neck and fastened it, making sure the latch could close without choking himself. It closed with a satisfying snap.
Sam felt an electric tingle coming from the contact points in the collar. Not painful, just tingly.
Without warning Sam lost his footing and fell. He braced his fall with his palms, landing hard on all fours.
That was weird. The blood must have rushed from his head. Sam went to stand back up.
Except he couldn't.
It wasn't like he was being physically stopped from standing, more than he couldn't properly form the thought to do so. He brain simply refused to send the signal to his arms and legs.
No way. No fucking way. The collar worked! It actually worked! Maybe he should order those X-Ray Specs after all.
Sam figured he would experiment with the limits of the collar until Allison got home. He didn't really have much of a choice; it was supposed to be impossible for the wearer to remove the collar themselves. Allison would have to do it.
Sam was still curious about the other supposed features of the collar. First he tried to speak. "I can still talk," he tried to say.
"Bark bark bark!" was what came out of his mouth.
Sam was pleased with himself, but he really wanted to test this thing. Summoning all his strength of will he focused intently on speaking. On the sentence "I can still talk."
"Bark bark bark!" Sam said.
Sam was really starting to get aroused now. This collar was the most amazing thing he had ever experienced. It had easily become his new favorite toy. His new favorite fantasy.
Sam decided he'd climb up on the couch while he waited for Allison. His brain, however, refused to cooperate.
*I need permission to go up on the furniture,* Sam realized.
That was too much. Sam dick was a white hot stone in his pants. He really should wait for Allison but he was sure he'd have plenty of sexual energy left for her. If anything he was doing her a favor rubbing out the easy one now.
Sam went to undo his pants, but found that he couldn't unball his hands from a flat, fingers-curled-palms-out position. Like a paw.
Wonderful!
That only aroused Sam all the further, but there wasn't anything he could do about it. Of course he could always rub himself through his pants but that would leave incriminating evidence that would be difficult to hide from Allison.
He would have to wait. He could live with that. Anticipation would only make the eventual moment of release all the more satisfying.
Sam went over to the front door, sat down in the manner of a dog, the only manner the collar would allow him to, and waited for Allison to come home. He wasn't deliberately imitating a dog's behavior here; it was simply the natural outcome of his excitement to see Allison and his behavioral limitations.
Sam sat staring at the door, waiting for Allison to arrive, for what seemed like forever. Finally Sam heard her key click in the lock and the door was pushed open.
Sam's throbbing, neglected erection had finally gone down, but the second he heard the key in the lock it sprang back to life even more powerful than before.
"Hey Sam, I'm home," she yelled, then almost tripped over him.
Allison looked down at Sam, sitting out of her line of sight right in front of the door where he would definitely be tripped over.
"What the heck are you doing?" she asked.
Sam raised his butt off his knees and held in "paws" in front of him in a begging position. He started panting. Allison also noticed for the first time that he was wearing a dog's collar.
"Oh," she said, with a sly smile. "Hello puppy! I had you confused with my boyfriend for a second. It must be those silly clothes you're wearing. Clothes aren't for doggies. Lets get you out of those right away."
She pushed Sam gently, not enough for him to fall over but enough for him to know she wanted him on his back. He deliberately fell backwards.
Allison undid the button on Sam's fly. That's when she noticed the painful erection he was sporting.
"Are you being a naughty doggy?" Allison asked.
She pulled Sam's pants off the rest of the way and threw them on the couch. Then she carefully removed his underwear.
"No!" said Allison, as she gave the head of Sam's penis a flick. "Bad dog. You haven't earned a treat yet."
Allison pulled Sam's shirt off over his head then quickly snatched off each of his socks. Sam was left completely nude save for his collar.
"You. Look. Adorable," said Allison. "Now what am I going to do with my cute new puppy?"
She got a mischievous smile.
"Oh I know exactly what I'm going to do. Let's see how good of a puppy you really are shall we? You stay here, I'll be right back."
The word "stay" resonated in Sam's mind. It became an absolute imperative. He was glued in place as surely as if he had been physically restrained.
Allison went into the washroom and shut the door. Sam could hear the shower running.
Sam really tested the power of the collar, trying his best to move, but he just couldn't properly form the thought. He just sat in front of the front door like a dog.
About twenty minutes later Allison emerged, dressed only in a towel. She smiled widely when she saw him.
"Aaaw, you didn't move because I told you to stay! You're so cute."
She leaned over and ruffled the hair on his head.
Sam was starting to get worried now. As hot as all this is he didn't think Allison realized the power she had over him. She thought this was another of their games and he was just playing along.
"You've been a very good boy so far puppy. And I know you want to keep being a good boy. There's something I've been asking my boyfriend to do for a long time now that he keeps refusing. But I think tonight is finally the night. You want to be a good boy right puppy? Good doggies do as they're told."
*Oh no,* thought Sam.
He tried to say no. To tell Allison that the collar was controlling him. It just came out as "Bark bark bark."
"I'm glad you agree," said Allison. "I know how much puppies like licking things."
Allison turned around, so her back faced Sam, and unwrapped the towel. She spread it wide so that it blocked the view of her naked body, teasing him a little, before dropping it. She was still wet from the shower and her firm ass had beaded up like a new car.
Sam's mind was so completely suffused with lust that he almost couldn't feel the fear.
Allison knelled down on the couch and stuck her ass out.
"Come here puppy," she cooed, "come lick my ass."
Before the collar had only ever blocked Sam from engaging in specific behaviors. Now it created an emptiness inside of him. A deep primal need akin to hunger or thirst. Sam instinctively knew that the only way to satisfy this need was to do as he had been commanded and lick Allison's ass.
He couldn't resist. His fear didn't matter, his disgust didn't matter, only this new hunger.
He crawled over to the couch on his hands and knees, stuck his face right into her ass, and began to lick it ravenously.
