"It's fascinating, the effect this can have," the man says, hand drifting back from your hair along your cheek. The nails have lengthened into black claws. "The hunger, the denial. The control. It will feel good, you know. You'll tell yourself it doesn't, you'll tell yourself you hate it. But you're not the first girl I've broken to the collar, and you won't be the last. Mark my words, there will come a day you beg me for this." He pulls his hand away, and then takes a step to the side around you, still holding your collar.
Around her, the hounds close in rapidly. One rolls onto its back and slides itself underneath of you, while another moves in front of you, sniffing at your face. The last two both move behind you. It all happens so swiftly and smoothly you have to assume they've practiced this.
"Cooperation," the man says. "You see? It has its...perks."
Exactly as he finishes talking, all four of the hounds lunge at you. The one in front of you rears up onto his hind legs and takes a half-step forward before falling, the front of his body landing on your back even as his cock is pressing at your mouth. The one underneath you shoves up into your pussy, as does one of the two on your back. The other aims a little higher, pressing in right under your tail and shoving himself inside.
The precise coordination begins to fall apart, after that. The hound in front of you begins to buck rapidly, fucking your face with short, fast strokes. The hound in your ass takes a slower and more measured response, thrusting slowly forward and then backing off, giving your body time to adjust to the intrusion, though it's still spreading you painfully wide. The last two thrust chaotically for a few moments before they find a rapid, hard rhythm. As one thrusts in, the other withdraws, keeping you from ever getting used to just one rhythm.
"I own you, right now," the man says softly, leaning down to whisper in your ear. "Do you realize that? How pure that is? Usually people belong to dozens, to kings and fathers, lovers and rivals. But here, now, you belong only and completely to me." He pulls the collar a notch tighter, letting you feel the pressure more clearly. "Treasure this moment," he whispers. "I will."
The hounds appear to be similarly enthralled, though not for the same reasons. The one in your mouth is bucking hard against you, shoving you back against the collar. Behind, your ass is finally beginning to relax, letting the hound really thrust inside. He and the hound beside him slip and slide against each other, both clawing at your back for stability. What little was left of your clothes before is being pulled away, exposing bare skin to the heat of the hounds' breath.
And underneath, well, the hound there appears the most enthusiastic of all. It paws softly at your belly, and laps at your breasts, running its rough tongue over your nipples. Its back arches more fiercely with each thrust, driving deep inside you and rubbing against the back of your hole. Between the two of them, they're spreading you painfully wide, though it has its upsides, as well: the hound beneath you is pushed far enough up that his shaft is rubbing against your clitoris on each stroke.
Despite his enthusiasm, it's his brother in your mouth that comes first, hammering against your face. The man holds you by the collar and keeps your mouth pressed firmly into the hound as he thrusts harder and harder. His knot swells up, and the man presses you forward to make sure that it locks up inside your mouth. Burning-hot seed shoots down your mouth as the hound pants. After a moment he begins to turn around, shoving his tail in your face at the same time as his knot locks his seed inside you.
The next to shoot his load is in your ass, spraying your insides with his come. He grunts, biting onto your tail and using it as a handle to pull you hard back into him and ensure that his cock is really buried up to the hilt. The hound before you is dragged a step forward by it, his knot forcing him to come with you.
The hound behind you lets go and turns around at the same time as the one beneath you begins panting and whining on each stroke. It's not much longer before he twitches wildly inside you and begins spraying into you, drenching your pussy in canine seed. As his knot swells it begins rubbing even harder against your clit, at the same time as he begins lapping more aggressively at your nipples.
The last of the hounds can barely move, now, between the friction of the knot in your vagina and the other hound beside him. But he does his damndest, biting the base of your tail to hold you steady as he thrusts into you. He's grunting with effort on each stroke, struggling to keep moving, even as his girth and the knot next to him are forcing your entrance open wide.
Its several minutes of this before he, too, begins swelling. The man holds your collar and keeps you steady as the hound strains, and strains, thrusting forward as hard as he can. Finally, with a wet pop, the knot slams home, trapping both cocks in you and forcing you open wide.
"Did you enjoy your treat?" the man says, stroking your hair and cheek gently. "I know your new friends did." With that he chuckles and goes back to lie on the bed again, watching as the lot of you collapse in a tangle of limbs and tails, still thoroughly knotted together.
