Climax

Tracey thought the stretching was over....but it wasn't. Because apparently when Hermione s building up to cum, that glorious knot only swells even more. Like a lead balloon, the knot grew larger inside her, stretching her to her limits. It was a miracle she didn't rupture the cavity altogether. The pressure was unbearable but the pleasure was so intense she didn't know whether to scream or moan.

"Oh, gods!" Tracey gasped, her voice hoarse from the muffled cries she had been holding in. "It's so big! So... much..."

"Yeah. You know it's coming" Hermione whispered in Tracey's ear, her teeth grazing the lobe. The knot had swollen so much, Tracey felt like she was being split in two, but she didn't want it to stop. The pain was a part of the pleasure now, a constant reminder of the power dynamics at play. The very idea of being bred by a Mudblood sent shivers down her spine and yet she found herself begging for more.

"You smell fertile" Hermione murmured, her breath hot and ragged against Tracey's neck. "I can feel your womb begging for my seed." The knot grew even larger, pressing against the limits of Tracey's body. It was a feeling of fullness that seemed to reach down to her very soul.

The Purebloods' eyes rolled back in her head, her cries growing more feral with each passing moment. Her pussy tightened around the knot, milking the cock that filled her so completely. It was a dance of dominance and submission, and Tracey had never felt more alive. The clap of Hermione's balls was the metronome building up to the encore, the faster the claps got the closer Hermione was to blasting her uterus full of Mudblood cum.

The brunette's thrusts grew erratic, her breathing ragged as she felt her climax approaching. The knot swelled even more, her head battering against Tracey's cervix with a **** that was almost painful. "Here it comes," Hermione groaned, her voice low and guttural.

The pureblood could feel the heat building inside her, the pressure of the knot growing almost unbearable. And then, with a roar that seemed to shake the very foundations of the library, Hermione came. Her seed shot into Tracey in thick, hot spurts, filling her completely. The knot pulsed with every release, sending waves of pleasure through her body that made her toes curl and her eyes water.

"Don't you move" Hermione's voice was a hiss, her eyes wild with passion. "I've got so much of my seed to give you."

Tracey's body was trembling beneath her, her pussy clenching around the knot that had swollen to a ridiculous size. The feeling of being so full, so completely claimed by Hermione was a head-blowing one. She could feel the brunette's hot cum filling her up, the knot ensuring that not a single drop would escape. It was a feeling that was both terrifying and exhilarating.

The warmth of Hermione's seed spread through her, a testament to the potency of the Mudblood's lust. She could feel the sticky wetness of it pooling behind the base of the knot, the angle of her own hips ensuring it all dribbled back down towards the waiting womb.

Tracey's eyes went wide as she felt the knot pulse inside her, releasing more and more of Hermione's seed. It was like nothing she had ever felt before, a feeling of being filled and claimed that went beyond the physical. She had read about the breeding rituals of in-form werewolves in ancient texts, perhaps that's got something to do with how Hermione accomplished all this, but she had certainly never thought she would experience it firsthand.

The brunette's hips slowed, her thrusts becoming more deliberate as she savored the feeling of her cum spilling into the Slytherin's womb.

Tracey could smell how Hermione's scent had gone up another gear, encompassing Tracey's own essence. It would do that for days to come, without Hermione even being around. It's a natural thing, the male wants every other male to know this female is off-limits, carrying their off-spring. Having Tracey smell strongly of Hermione's dominance for long periods, is the desired effect Hermione wanted. Montague literally couldn't call his former girl his own, with her body reeking of some other dominant sex partner.

The two of them lay there, panting, their bodies slick with sweat and sex. Hermione's knot remained lodged inside Tracey, a constant reminder of what had just transpired. The brunette leaned down and kissed her, a gentle kiss filled with the promise of more to come. "You're mine now," she whispered, her voice a soft purr. "My little Pureblood baby mumma."

Tracey could feel the weight of the knot, the way it stretched her and filled her so completely. Her pussy was sore, but it was a delicious ache that she knew would only serve to remind her of this moment for days to come.
