Discovery

Hermione's hand guided Tracey's hips in a rocking motion, her own eyes half-lidded with pleasure as she watched the black-haired expression shift from pain to something else. Something pleasant, something more primal. "That's it," she whispered, her voice a siren's call. "Ride this cock. My blood doesn't matter, it's just a big cock. Ride it like you want to."

Tracey's body began to move in response, the pain slowly receding to be replaced by a building pressure, a need that she had never felt before. She had heard the whispers of what happened between a man and a woman, but this was nothing like what she'd read and been told. This was raw, powerful, and utterly overwhelming.

Her movements grew more confident as she found a rhythm that suited her, her pussy stretching and accommodating the thick cock. The knot at the base of Hermione's shaft rubbed against her clit with every thrust, sending waves of pleasure crashing through her body. The pheromones had taken over, turning her into a creature of instinct, her mind a fog of lust and desire.

Hermione heard a call from distant, not thinking much of it. But when it came a second time, closer than before and accompanied by the name "Tracey" she knew that Montague had grown tired of waiting for his girlfriend. Hermione's hand slaps over Tracey's mouth, smothering her cries even as she still bounced the girl on her dick.

"You need to be quiet now," she whispered urgently, her voice a mix of threat and promise. "If you scream, if you alert him, I'll stop."

Tracey's eyes grew wide at the notion this would be taken away, so she nodded frantically, her body still moving of its own accord. The footsteps grew closer, echoing through the library like a warning bell. Hermione's hips bucked faster, the sound of their flesh slapping together muffled by the velvet cushions.

There was a small possibility he could wander into the nook Hermione had found for them to fuck in. It was the very last space you could find and hardly anyone but herself would ever get round to finding a spot here to study. It logically also wouldn't be where a girl would go if they were sourcing ink. Nevertheless the slight chance that he might just check this space, had Hermione with her wand out pointing at the entrance to their section. If he showed his stupid face, he'd be stunned immediately.

The footsteps grew louder, the tension in the room rising with each step. Tracey's movements grew erratic, her muffled whimpers getting quieter, and her eyes darting to the entrance. Hermione gripped her chin and **** her to look back at her, her eyes warning her to not divert her attention away from riding her cock.

Tracey did as commanded, focusing only on bucking and grinding on Granger's dick and ignoring Montague's close proximity. The footsteps grew closer, and it was all she could do to keep her moans in check and her hip movements steady. Hermione watched the entrance with a hawk-like gaze, her hand tightening around Tracey's mouth as the resolve grew in her eyes.
