Where were we?

Montague never rounded the corner. His calls grew fainter, and eventually they were too distant to be a problem. Hermione's heart slowed down to a steady beat, and she let out a silent sigh of relief. She waited for a few more moments, making sure he was truly gone before she released Tracey's mouth.

"Good girl," she murmured, stroking Tracey's hair. "You can scream all you want now."

The pureblood's whimpers grew louder as she threw her head back, the pheromones making her pussy clench around the invading cock. Hermione's own pleasure grew, her moans mixing with Tracey's. The tightness of the girl's virgin cunt was heavenly, each movement sending shockwaves of pleasure up her shaft.

With a sudden burst of strength, Tracey raised herself up on her shaky legs, the cock sliding almost all the way out of her. She paused there for a moment, the tip of the cock teasing her stretched hole, before she slammed back down onto it. The sound of her pussy smacking against the knot was loud and obscene, echoing through the hidden nook.

Hermione's eyes rolled back in her head, a moan of pure pleasure escaping her lips. The tightness of Tracey's cunt, the way she clamped down on her cock with every movement, it was like nothing she had ever felt before. Pureblood pussy was great, and Hermione enjoyed the desecration of them as much as she did the physical pleasure.

The two of them moved in a frenzied dance, their bodies slapping together with a rhythm that seemed to resonate through the very stones of the library. Tracey's breasts bounced with every thrust, her nipples hard and sensitive, begging for attention. Hermione leaned forward and took one in her mouth, suckling and biting gently, her other hand stayed clawing and groping Tracey's butt.

The raven-haired girl's eyes rolled back in her head, her hips bucking wildly as she rode the cock that had invaded her very soul. Her cries grew louder, her movements more frantic, as she chased the elusive orgasm that hovered just out of reach.

Hermione watched with a mix of fascination and satisfaction, her own body tightening with every gasp and whine that Tracey gave. She knew that the Slytherin's climax was approaching, the wet cunt smell in the air growing stronger with every passing moment. It was a heady scent, one that seemed to fuel her own arousal as much as it did Tracey's.

"You're going to come for me," Hermione whispered, her voice thick with lust. "You're going to know that you're being bred by a Mudblood."

Tracey's eyes snapped open, a trace of reality leaking out her musk-induced stupor. But it was too late. The pheromones had her in their grip, and she could feel her orgasm building, a crescendo of pleasure that she couldn't resist. Her pussy clamped down on the thick cock, her walls spasming as she reached the peak.

"Ahh...yes," Hermione growled, feeling the warmth of Tracey's orgasm around her cock. "Soak the cock of the dirty blood. Show vulnerability to your so-called inferior."

Tracey's body convulsed, her pussy pulsing around Hermione's cock as she came. It was a powerful orgasm, one that seemed to shake her to her very core. Hermione could feel juices washing over her great fat knot, making its entry in a little while that little bit easier. The juices ran as far down as Hermione's balls, pristine and round and full of kin to dump into pureblood witches.

With a grunt, Hermione stood, taking Tracey with her, their bodies still joined. She turned and carried the blonde to the floor, laying her down on the cold stone with surprising gentleness. She hovered over her, her cock still buried deep inside, and stared into her eyes with a hunger that was almost feral. Her hips settled atop Tracey's thighs, their arses meeting in this new breeding position.

The Slytherin's legs wrapped around her waist, her heels digging into the small of Hermione's back as the brunette began to thrust in earnest.

Tracey's eyes never left hers, the glazed look of lust mixed with something darker, something that hinted at the knowledge of what was happening to her. But the pheromones had her, and she couldn't fight it anymore. Her pussy clenched around the invading cock with every stroke, the wet sounds of their union echoing through the empty library.

Hermione leaned down and claimed Tracey's mouth in a deep, hungry kiss, her tongue probing and conquering the Slytherin's mouth with the same intensity as her cock was conquering her pussy. The taste of Tracey's fear and arousal was intoxicating, making her thrusts grow more urgent.

The two of them moved together, their bodies a tapestry of sweat and desire. The candles flickered, casting shadows that danced across their skin, painting them in a palette of dark and light. The world outside the library had ceased to exist for them, the only reality was the primal need that had overtaken them both. But it was about to get even more beastial.
