Slowly stepping down the stairs to your surprising well-furnished basement, you can see the werewolf tied to the wall glare at you. Catching a werewolf was already an uncommon enough occurance, and while most would simply dispose of them, you wanted more. Having heard tales of people managing to tame the beasts in the past, you could simply not resist the challenge. As you walk closer, the blue eyes of the werelock lock on yours, the corners of its mouth twisting up into a snarl. Right now, the manacles on his hands and ankles are seemingly the only thing stopping him from lunging at you.

Leo's eyes narrow and his body tensing, every instinct screaming at him to attack you for suggesting such a thing, but there is something else in his eyes too...a spark of curiosity maybe? He growls deep in this throat before he speaks. "Why should I do that?"

Leo's body language subtly changes; his posture softens and his tail wags slightly behind him, almost like a dog that has seen something interesting. The curiosity in his eyes now becomes increasingly dominant. "I...I could do it...willingly..." he stammers before hesitating, looking you up and down once more. "...but what's in it for me?"

Leo licks his lips nervously, eyes flicking over your body one more time before settling back on yours. He looks conflicted for a moment, but then he gives in, growling lowly as his eyes begin to glaze over with desire. "Alright...I'll do it."

With that, Leo hunches down, pressing his powerful hind legs against the wall and presenting himself before you. His tail begins to wag slowly back and forth behind him, exposing his dark red and swollen member already leaking pre-cum onto the concrete floor below. "Just hurry up with it," he says through gritted teeth, a mixture of lust and anger in his voice.

The werewolf growls again, more out of frustration than anything else. He hunches down even further, bringing his massive canine cock closer to your waiting entrance. With one powerful thrust, he pushes into you, driving the thick member deep inside in a single powerful motion that elicits a sharp gasp from both himself and you.

The sensation of being filled so completely and violently triggers an automatic reaction within him, sending waves of pleasure coursing through his body as his hips begin to buck and thrust, driving his cock deeper into your tight hole with every stroke.

Leo's eyes roll back in their sockets, showing the whites as he bites down on his lower lip, feeling himself nearing climax already. "You feel...so good..." he pants between gritted teeth, the werewolf's incredible stamina kicking in as he continues to plunder your tight hole mercilessly.

Leo snarls and pulls his hips back violently, retracting his throbbing member for a moment before slamming it back into you with twice the force. "You're not my master!" he growls through clenched teeth, eyes blazing with anger as well as lust. His pace quickens even further, driving his cock relentlessly in and out of your tight hole as if trying to prove some sort of dominance over you.

As you prepare the syringe and approach him, Leo's eyes widen with fear, his heart racing even faster as he tries to think of a way out of this situation. He hadn't expected something like an aphrodisiac injection; it throws him off guard completely. He tenses up involuntarily at the sight of you holding the needle, ready to strike, unsure if he should fight back or submit further.

Leo arches his back violently, letting out a sharp yelp of pain and surprise as the liquid hits his sensitive flesh. The stinging sensation is only momentary however; within seconds it's replaced by an intense burning sensation that quickly spreads through his groin. His cock begins to throb obscenely now, reacting violently to the powerful aphrodisiac coursing through him.

Tears of pain and frustration gather in the corners of his eyes as he looks down at you with anger and humiliation. But there's something else there too...something much more powerful. The werewolf's instincts take over, overriding his ability to think rationally or ignore what his body is telling him. He growls deeply in his throat before lifting a paw and attempting to swipe at you, forgetting for the moment that he's still restrained by chains.

Leo's eyes widen and his fangs lengthen at the threat, his body trembling with desire and fear. Unable to control himself any longer, he thrusts his hips forward violently, driving his engorged member deep into your welcoming hole. With a feral growl, he begins pounding you mercilessly, every stroke sending shockwaves of pleasure through both of you.

His powerful hind legs kick and thrash against the wall behind him, while his front paws claw at nothing but air as he tries desperately to free himself from the chains that bind him. Sweat beads on his furred body, trailing downwards towards your writhing forms below. His canine cock throbs obscenely inside you now, demanding release as it grows ever larger with each thrust.

A pained grunt escapes his lips as he feels himself getting closer and closer to the edge. His mind screams at him to hold back, to show you that he's still in control, but his body betrays him once again, its lust overriding any rational thought. With a final thrust that drives him over the brink, Leo releases his seed deep inside your piss hole, filling you completely with his warmth as he growls out his pleasure.

His hips stutter to a halt as the last of his strength ebbs away, leaving him gasping for air and trembling all over. The knot forming at the base of his cock pulses against your insides as it seals shut, trapping his essence within you, marking you as his in the most primal sense possible.

For a long moment, he simply lies there, catching his breath and gathering his thoughts. When he finally speaks, his voice is gruff with both exhaustion and anger. "You...you'll regret this..." he growls through clenched teeth, glaring up at you from where he's sprawled on the floor.
