As it turned out, Jess had very good reason to keep people (Morgan in particular) far away from her computer. She had a porn collection a hormone addled teenager could only dream about. From amature first timers to hardcore bdsm lifestyle practicers like the Panda and Cobra women.


Delving into that series in particular was quite the journey. Apparently the Panda girl was her parents' willing submissive, hoping to make her father happy after the death of her mother. It seems the girls father got really into it, going so far as hiring a professional dominatrix to train the malleable young teen, the Cobra lady from the first video. The videos claimed that the girl (her name was Lin) started her training at age 14, 2 years ago, with hopes of making her into a full fledged submissive to her father by the time she was 18. Judging by the extremity of the girls training Morgan wasn’t sure how much of her would be left by the end, eyeing the segments labeled “brainwashing.”


Digging deeper he came across a file simply entitled “cub.” Raising a questioning eyebrow to Jess only caused her to blush and look away, probably wishing she could just disappear into her chair.


“You know, I always knew you were a freak, but I never thought you were this bad.” He sighed in mock disappointment and shook his head, but in the back of his mind he was thinking of just what the file contained. He’d have to look through it alone. His cock throbbed at the prospect.


He spent several more hours sorting through the mountains of porn his step-sister owned, often commenting on Jess’ rather extreme tastes and playing with her caged tool and the chastity app. Finally he felt his cock bothering him too much to continue concentrating. He needed relief. His eyes fell on Jess, her own gaze fixated on the tent in his pajamas and looking bewildered.


“See something you like?” He mimicked her mocking tone from earlier, slipping his engorged cock out for her to see. “Bigger than you thought, huh? Though judging by those dildos in your closet nothing you can’t handle, right?”


Eyes widening the bound Dobie struggled uselessly in her bindings, her chair rattling but otherwise getting nowhere. Coming to a stop when the powerful electric shock on par with a taser coursed through her balls and drew a muffled screech from her as she tensed and writhed uncontrollably.


“Now now, remember who’s wearing the pants right now Maggot.” Morgan held his thumb over the punishment button threateningly. “Your keys are locked up in MY safe, meaning your MY bitch until I say otherwise. You get that through your thick skull?”


Jess was terrified by the growing edge in Morgan’s voice. She had never seen this side of him before. Where was the little pussy who used to cry to his mom when she stole his ice cream? Who sobbed like a bitch when she dissected his teddy bear playing “surgeon?” What scared her the most though was the tingle in her crotch when he insulted her, ultimately useless with the cage locked on but unsettling nonetheless.


Standing up and removing his pajama bottoms the fox moved behind her out of Jess’ sight. She watched his hands encircle her and begin to roughly grope her breasts. Despite herself she began to breath raggedly, his pinches and twists to her nipple studs sending unwanted jolts of pleasure through her body. Resting his chin on her shoulder he watched with interest as a bead of pre cum formed at the tip of her cage and slowly dribbling out. Gathering it up he rubbed the fluid into the dog's nose forcing her to smell her own arousal, something that alternately humiliated and turned her on immensely.


“I’m going to release your wrists now. If you know what’s good for you you’ll keep them on your arm rests until I say otherwise. You know how high this thing can go and I’m not afraid to use it. Understand Maggot?”


Jess nodded submissively, feeling the lock connecting her arms behind the chair come loose. Slowly she moved her sore limbs back to her front and assumed the instructed position, her nails digging into the faux leather. Circling back around Morgan releases her legs one at a time, letting her stretch and work the kinks out of her muscles. She debated kicking him but with the keys locked up there would be no easy way out of her predicament. Not to mention who he had already sent that video to.


“Stand up and put your hands behind your back,” Morgan commanded and she followed, shifting from one foot to another anxiously as he moved the chair out of the way and used the padlock to once again bind Jess’ wrists.


Taking a firm hold of her nipple he guided the gimped Pinscher over to her queen sized four post bed.


“On the bed. Knees, head down and your ass on the air,” he said curtly with his phone never leaving his grasp.


Standing back Morgan slowly stroked his cock while watching his step-sister struggle on to the bed, taking special pleasure in her pained whimpers when the straps pinched her sensitive balls. Finally settling into position, breathing heavily and clearly turned on looking at her drooling cock. What a slut, he thought to himself.


She deserved punishment.


Leaving Jess to catch her breath and contemplate the coming ass fucking from her little brother he ventured back to the closet of goodies. Selecting a leather blindfold and a scuffed wooden paddle he stalked back over to his unsuspecting victim. With her front pressed into the covers she had her head turned away from him, almost like she predicted him slipping the leather material over her eyes and tightening it. Regardless she didn’t fight it. Nor did she fight his spreading her legs and using the leftover straps to secure her ankles to the bedposts, leaving her open and vulnerable.


“Good girl,” he cooed into her flattened ear.


He took some time to let her stew, sitting back and watching her test the bindings only to find no give. Pulling up his camera again he took several snaps of her puckered tailhole; maybe he would make a “before and after” set out of it to show his friends. Any guilt he felt at taking advantage of her was easily overcome by the countless memories of her incessant harassment.


Rising he took up position behind her, holding the paddle like a batter at the plate. He took a few practice swings first to try and familiarize himself with the weight and feel of it, finding it surprisingly easily to handle. Cocking his arm back he let loose with a hard smack square on Jess’s ass.


*Smack*


For a moment Jess gave no indication that she had even felt the strike—her brain took a second to even register what happened. Then the pain flooded in and despite herself she threw her head back and howled in pain, shaking her reddening ass in a useless attempt to avoid his blows but only succeeding in making the target all the more appealing. Licking his lips Morgan swung again, catching the underside of Jess’ ass and clipping her balls in the process.


To Jess the blow felt like a kick to the stomach, knocking the breath out of her. Drawing in a pained breath she let loose a feral screech, clearly audible even through the pump gag.


“That one had to hurt,” Morgan taunted before landing another strike to her butt that made his cock throb. Jess’ cock too, judging by the incessant dribble of cum leaking from her cage. The bitch loves it, he thought gleefully.


He landed a couple more to really drive her into a frenzy before dropping the paddle, jumping onto the bed behind her and spreading her ass. Unconsciously he stretched his tongue out and gave Jess’ pucker a long slow lick, sending a shiver down her spine. He loved the way it winked at him. Sucking on a finger he drove it in, feeling her stiffen but rather quickly relax as he felt around. Obviously not a virgin, but still tight considering the size of toys she played with.


Withdrawing he spent a little more time teasing her ass with his tongue until he felt she was suitably lubed for him. Placing his cock head at her entrance she stiffened again and he waited until she finally relaxed before thrusting, burying himself halfway as he hissed in pleasure and Jess groaned.


“That’s it you fucking cunt. You’ve had this coming for a long time.”


With one hand holding her hip steady and another squeezing a tit so hard it bulged between his fingers he pulled back and thrust again, quickly building up a rhythm as his knot began to form. With a degree of narcissistic sadism unheard of by him he began trying to fit it all the way up the protesting Doberman’s ass, growling in pleasure and when it finally slipped in with an audible groan from Jess.


The feeling was too much for the horny young fox and he howled as he let loose, his seed filling Jess’s backside and leaking around his cock. Drained he collapsed onto her back, panting heavily and drifting off to sleep. His knot kept them tied together for several more minutes before finally wilting enough to slip out (to Jess’ great frustration—she was THIS close to actually getting off!)


Huffing in disappointment she felt exhaustion overwhelm her from the ordeal and she fell into a light slumber herself.


The bleep of Morgan’s phone notifying him of various Discord messages woke him several hours later. Looking down he smiled at his still bound step sister. The slow even rising and falling of her shoulders told him she was asleep.


“Right where I left you,” he whispered, slipping off the bed and checking his phone. Just the usual bullshit; his friends sharing videos or shitposts or pet photos. Nothing directly involving him.


His stomach rumbling brought back to attention that he was hungry, having only taken a bite of his breakfast before this walking whole thing started this morning. Jess would probably be hungry too, he thought as he looked over to the dog herm. His mind began to turn at the possible ways he could make the process degrading and humiliating for his new slave.


But first he had to wake her up. Pulling up the app on his phone he chose “attention” and pressed the middle button. Electricity courses across the bound Doberman’s cock and balls, quickly jolting Jess out of her sleep and sending her jerking in her bindings as the current continued for a full 30 seconds—designed to ensure the sub was fully alert and awake.


“Wakey wakey, eggs and bacey,” he teased over Jess' muffled squeals. “What do you say to a little lunch? That’s the spirit!”


Releasing her thighs but leaving her wrists bound and the gag and blindfold in place he hauled Jess to her feet. Once again taking cruel hold of her nipple he led his new slave carefully down the stairs into the kitchen, having her kneel down next to the counter with her knees spread. The window led out to their backyard so there was no risk of somebody happening to glance in and see them, but he went about drawing the blinds in the living room nonetheless in case he wanted to bring her there.


Checking the time he gauged that he had around 4 hours before anyone got would possibly be home; plenty of time for some fun during lunch. Making himself a turkey sandwich he looked through the cupboards looking for something suiting Jess’ new station at his feet. Pulling down a can of oatmeal he decided it would suffice until he could think of something better. Without seasoning it would be a tasteless gruel, nutritious but wholly unpleasant to eat. Boiling some water he filled a bowl about halfway with the mixture and set it in front of Jess. Watched her sensitive nose twitch as she smelled it followed by a low growl from her stomach.


“Hungry?” He asked rhetorically but she nodded anyway. “Alright, I’m going to take the gag and blindfold off. No talking unless I give you permission, understand?” Another blind nod.


With the gag finally off Jess could finally rest her sore jaws, forced open for so long around the huge rubber bulb filling her muzzle. Looking down distastefully at the meal set before her she glared at her brother sitting in one of the dining room chairs about to dig into his sandwich.


“You don’t expect me to actually eat this shit, do you?” She asked incredulously, immediately regretting it when she saw the look of anger on Morgan’s face as he picked up his phone. Before she could even think of apologizing her crotch exploded in agony, like someone had kicked her with a steel toed boot. He waited until she calmed down to speak again.


“That’s medium high, by the way. There’s three more levels above that. Now what the fuck did I just say about speaking without permission?”


Jess opened her mouth to speak but he cut her off. “I said don’t fucking do it, didn’t I? But you seem to think that means say whatever you want, even swear. You’ve got a lot to learn it seems.”


He smiled at her. “I’m going to have so much fun teaching you. Now shut the fuck up and eat. Next word I’m having you piss all over that oatmeal. Don’t test me.”


Faced with the option of either swallowing her pride and eating something unpleasant or punishment followed by eating something even more unpleasant she decided on the lesser of two evils. With her wrists bound the way they were she was forced to bend down and eat with only her mouth, her ass sticking up and bobbing as she struggled to get the watery gruel into her mouth.


For his part Morgan found the whole ordeal hilarious. He would have to make this a regular thing it was so entertaining watching her lick the bowl clean. He would have to get a dog bowl, too.


Finishing the tasteless slop and unsure of what to do she resumed the kneeling position he had originally put her in, back straight to try and alleviate the growing pain in her shoulders. Silently Morgan collected their dishes and washed them, setting them on the rack to dry.


“That’s the last dish I’m ever washing, by the way. From now on my chores are your chores. You do the dishes, you take out the trash, you clean the bathroom. Understand?”


Since he hadn’t given her permission to speak she simply nodded, her blood freezing at his exasperated sigh.


“Okay I’ll let that one slide because I’m starting to realize you’re a lot stupider than I thought. When I say do you understand, that means you say ‘yes Master,’ or ‘no Master.’ Now, understand?”


“Yes Master,” Jess whispered, letting out a cry as a low jolt jabbed her cock head.


“Louder, bitch. I can’t hear you.”


“Yes Master!” She yelled, her face growing hot as she wondered if the neighbors heard her.


“Good, now I want to see you crawl back up to your room. Then you’re going to put on a little show for me with those dildos I saw. It’s gonna be fun watching you deep throat that horse cock.”


Humbled by the meal she silently obeyed when Morgan released her wrists, slowly crawling across the rough carpet and up the stairs to her bedroom, now more like a prison.

Sunday Morning:


Back on the bed Morgan began jerking his morning wood with one hand while his other played with Jess’ caged package. Her whimpers were a potent aphrodisiac to the horny fox boy.


Straddling her stomach he slipped his dick between her tits, grabbing each one like a handle and squeezing them around his throbbing pole. Jerking his hips in an uneven timing he groaned, tongue lolling in pleasure while Jess glared at him, her own neglected cock crying out to be played with.


All too soon he felt his climax engulf him and he howled as he came, shooting his load across the Doberman’s face and getting some in her eye. Slipping off her he laughed as she tried in vain to get the sticky, salty load off her.


“That was fun but we gotta get ready for the day now, Maggot. Let’s grab a shower then we’re going to the mall. I’ve been looking through your clothes and I don’t see anything suiting a fresh slave girl. No skirts, stockings, even halter tops, for shame! So we’re gonna spend today getting you properly fit for the role. What do ya say? That’s what I like to hear,” he said to the gagged herm. “You’re gonna look perfect when I’m done with you. My personal little bimbo slut.”


Jess could only lay in her bondage while she listened to Morgan’s one-sided conversation with growing horror and arousal. Part of her wanted to break free and escape this situation, and another (the self-loathing, masochistic part) wanted to see just where her step-brother would take her.
