The dungeon was sparsely lit by the various scented candles mounted to the walls, casting a sinister shadow across the back of the mare currently busying herself with dressing for the part. Already decked out in a tight cupless underbust corset and a pair of black silk thong panties that conformed to her camel toe she hummed a tune as she slowly, teasingly slid first one then another pair of fishnet stockings up her thick thighs and clipped them to her garter belt. A snort of frustration to her left made her glance over and smile sadistically.

"You look really pathetic right now, you know that?"

Sitting in the middle of the room was a stallion, a ball gag filling his mouth and sturdy leather straps keeping him firmly seated to his chair.

Her stallion watched her every move, his cock standing at full mast and twitching in pleasure every couple seconds. He was horny, that much was obvious. But not scared. The mare frowned as he met her eyes and cocked an eyebrow, smiling what little he could around his gag.

A silent "this all you got?"

She grit her teeth. She would show him.

Striding up to him slowly she cocked her hip to the side and gave him time to drink her in. His eyes slowly roam over her, from the tips of her ears down her long black hair partially obscuring her face; over her fulsome breasts tipped with thick pink nipples, down her chubby middle and wide hips to focus on the valley between her legs, specifically her panty-clad vagina. She watched with interest as his cock pulsed and a small bead of pre formed at the tip and ran down his shaft.

Goddammit, he was still just horny! How the hell do you act imposing when you're a full foot and a half shorter than your sub!? Her eyes fell to his balls, sitting unprotected on the chair's seat. Perfect.

Matching his cocky gaze she slipped her hands over his muscular shoulders and slowly began raising her leg, as if she were about to mount him. The stallion looked at her, surprised but all too willing if it meant release. Instead of mounting him though, she pressed her knee into his sack and slowly leaned into it, reveling in the way the stallion's face went from surprise to anger to pained agony in a matter of seconds. His erection slowly wilted and retreated back into its sheath.

"Scared now, bitch?" She whispered, and he submissively nodded, wincing. Anything to get away from the unbearable agony of his nuts pressed almost flat. Grinning triumphantly she stepped back, her nipples stiff and cunt wet. "Good. Time to get started."

Strolling over to the various implements she made a show of deliberating, her finger to her mouth like she was a child picking out a sweet at the shop. The stallion tried his damndest to get a look over her shoulder but his bindings held tight, cutting into his wrists as he strained. Defeated and resigned he slumped as much as he could, his head dropped. Quickly shooting back up when the first swing of the leather barbers strap made contact with his sheath and nuts and knocking the breath out of him.

The mare giggled sadistically as she watched his fruitless struggles, his thigh muscles clearly defined as they strained against their straps in an attempt to close his legs and his eyes almost completely white. In response she laid another burning line, centered on the opening of his sheath, his cock head beginning to poke out. His scream sent an oh-so-satisfying shiver down her spine and sent her tail flicking excitedly. Drawing yet another muffled yell from the stallion she snorted and slipped a hand down the front of her panties to begin gently fingering her cunt, her eyes half lidded while she listened to his pitiful whimpering and muffled pleas for mercy. All of which fell on deaf ears.

Looking back up to her toy she grinned at the sight of his thick equine cock again standing at full mast, his nostrils flaring at the smell of her arousal. If not for the restraints he would have already tackled her, wrestled her panties off and pumped a load of foals into her. But she was in control. Thus his needs weren't taken into account.

"Damn, you can get hard with your balls burning like that?" She asked incredulously before her look slowly turned predatory, something that did little to put the stallion at ease. "I have an idea for a little experiment, you up for it?" A muffled denial, emphasized by shaking his head so hard it made his eyes hurt.

"Perfect! I always knew you were a total masochist at heart! Remember how hard you came with the chili oil on your nuts? You'll love this!" Gathering her tools she laid them out on a mobile tray and slowly wheeled it over to the protesting (but still incredibly hard) male, putting some extra sway into her wide hips and pressing her tits together with her elbows. The move had its garnered effect, sending him into near hysterics centered around the need to fuck something, anything.

Normally an erection feels good-but that tends to fade after almost a half an hour of nonstop sensitivity, the slightest breeze over the cock head sending it twitching. The stallion was on the verge of crying now, his need was so great. The perfect state for the mares intended game. Taking a thin leather string she bound his ball sack tight, encircling each egg and wrapping the top of his scrotum tight where it connected to his cock. The stallion tried to keep a poker face about him while she worked, slowly degenerating to anxious sweating as the pressure around his sensitive orbs increased. Finally stepping back to survey her work she reveled in his expressions, watching his balls slowly discolor and the pain beginning to build. Still his cock remained at full mast, a line of pre cum bubbling up from the tip then running down the shaft.

"God you're such a pain slut, look at you! Your little sister is about to torture these worthless balls until you shriek and you're dribbling all over yourself! I know you've been stuck playing bottom for all the guys but have some decency! I let you out of your cage and you nearly slapped me with that thing." She stabbed her finger accusingly at the offending horse cock.

Blushing furiously, he looked away in shame. Of course it was true. He was just a slut. A shameless whore who got off being degraded, used and tortured for the amusement of his betters. In evidence his heart began to race and his cock twitched as he watched his sister select a box of sterilized needles, pulling one out and advancing on him menacingly.

"Time for the real fun, bitch." She said, kneeling between his spread thighs so she was eye-level with his oxygen-deprived balls. Taking a cruel hold of his bound sack she held it steady with one hand while the other lined the needle up between each egg. His terrified snorts almost euphoric to the young mare, mounting squeals as she slowly pushed it in until just the round head was visible.

"Oh shut up, I've barely done anything yet." Selecting another needle she placed the tip against one swollen testicle and looked into his terrified eyes. Using the tip of her finger she pushed it in past the slight resistance, watching his eyes squint shut and a muffled screech very unlike a big, buff stallion escaped him. She gave him a minute to recover, slowly strumming her clit under her panties and twisting a nipple while he panted and whimpered-his hoof tapping in a rhythm only he could seemingly discern.

Finally managing to regain some semblance of composure he pleaded with his eyes, hoof tapping incessantly as she wiped her wet fingers off on his chest and picked another needle. Slowly, agonizingly slid into the other bulging testicle. Not giving him time to catch his breath she pushed one through each of his nipples as he watched in disbelief. Rising she picked up a cat-o-nine-tails.

"Let's see if you keep that boner after this, slut." She twirled the whip above her head, watching the terror build in his eyes. Cocked her arm back, and-

"Enough, Hazel." The command came from their left. Enshrouded in darkness an older mare sat in a leather-covered recliner, dressed in a latex catsuit and smoking a cigar. A large, muscled tigress knelt next to her seat, arms kept in a box binder and legs hobbled. A leather blindfold covered her eyes but her mouth was free. Taking a hold of the Tigress' short blonde hair she wrenched her head back and on reflex she opened her mouth wide to unflinchingly accept the still-red ashes tapped onto her tongue before being released and allowed to swallow.

"What's up, Mom?" the young mare asked quizzically. "I thought I was doing really good, he wasn't safewording or-"

"Present." The older equines deep, commanding tone cut her off and, setting the whip down she meekly assumed the position her mother had so often trained her in. Spreading her legs as wide as she could, thrusting her chest out and crossing her hands behind her neck she kept her eyes forward looking at the wall behind her brother. She heard her mother stand up; the sound of her hooves clopping on the concrete floor as she walked over to Hazel's older brother, her son and released one of his arms and left the rest to him.

Leigh grunted in pain through clenched teeth when he carefully pulled the needles out of his nipples, testicles and scrotum. He stood up and rubbed his sore bits for a minute before assuming the "present" position as well. Arabella looked over the damage herself to make sure her son didn't need to be sent down to Doc for first aid. Satisfied she selected a heavy collar and turned her attention to Hazel.

"You have an observation problem, Hazel. I taught you a dominant needs to be hyper aware of their submissive at all times." While she talked she wrapped the collar around Hazel's neck and padlocked it in place. Hazel kept her composure but her mind was racing. What did she do? She wasn't paying attention? When? How?

Her wrist was seized and hand stuffed into a leather mitt. Her other hand followed suit and they were quickly connected behind her back with another lock.

"You neglected to notice that your brother was safewording after the second needle. How many times have we been over this? If one of you can't speak you tap one foot 3 times in succession. But I watched you play with yourself and keep going. Seems you still have a lot to learn." Hazel tried to respond but the second she opened her mouth it was filled with her own ball gag, its web of straps wrapping around her head and tightened cruelly. She felt her mother begin to unlace her corset.

"You don't deserve to wear these yet." Arabella sighed in visible disappointment while she stripped her daughter to her fur. "I thought you were ready, but I guess that's just wishful thinking on my part. Calling me Mom was a big mistake too, cunt. You can look forward to spending the next couple months at the least on your knees. You have no one to blame but yourself."

Turning she addressed Leigh. "You did well. I'll let you oversee her training for the next couple weeks. You'll be allowed out of your cage during that time, with free access to her holes. Make sure she's belted when you're not using her, you know how much she masturbates otherwise."

Arabella slowly sauntered back to her chair, taking out a strike-anywhere match and lighting it off her Tigress' forehead she lit her cigar again and watched Leigh manhandle his little sister to a kneeling position on the floor, her head pushed to the ground and her ass pushed up as high as she could with her tail raised out of the way, exposing her drooling cunt and tight tailhole. Whimpering as she looked over her shoulder at him in anticipation and fear. The stallion took his time getting himself ready, coating his length in lube and pumping his shaft a few times while he talked to her.

"Man, you really fucked up Sis," he said smugly. "All you had to do was pay a little attention and you had me for a whole month." He knelt down and settled his cock in the valley of her ass cheeks, slowly sawing it back and forth and feeling her shiver. "Now I get you for way more than that! Honestly I should be saying thank you, but my balls still hurt."

She felt him position his head against her inexperienced tailhole and a pang of dread jolted through her spine. "Sooo, since you were a pain in my balls I'm going to be a pain in your ass, literally." Grinning, he thrust his hips forward and buried half his cock into her ass with one stroke. He nearly came from her squeal alone. Taking a hold of her long hair he wrapped it around his hand to keep a good hold as he withdrew then thrust in deeper again.

Stroking herself through the opening in her suit's crotch and puffing at her cigar Arabella watched her children, her slaves, go at it. Leigh snarling any number of degrading things at his little sister. Seizing a breast and squeezing possessively. Oh what the hell, she thought. Grabbing onto her Tigress' hair she dragged the buff girl in front of her and pushed her face into the mare's cunt. Immediately she got to work, running her rough tongue over Arabella's slick folds, tensing it and fucking her with the appendage and occasionally sucking and nipping her hard clit.

Wrapping her legs around the feline's head she panted and moaned, twisting her nipples hard as she watched the young stallion rutting his mare. Grunting in unison, Arabella and Leigh both shouted through their climaxes, flooding Hazel's ass and coating the Tigress' face in love juice. Shoving the Tigress off her, Arabella relaxed in the afterglow while she watched Leigh pull out and his cum slowly leaked out of the mares gaped ass.

Cleaning himself up, the stallion perused the instruments that just a half hour ago were intended for him. Eyes falling on a bottle of chili oil he remembered her use of it. Gears turning in his head he smiled devilishly and advanced on the frightened mare, bottle in hand.

"Let's see, I have a little experiment I want to try, you up for it? Good!"
