"You are such a Gryffindor." He laughed as he looked at the woman in his arms.
"What do you mean?" she asked, her voice muffled by his chest as her head rested on his body.
"You're purring like some kind of feline. Only a Gryffindor would curl up against me and purr." He replied.
The woman moved away from him slightly, and propped herself on her elbow, a slight smirk oh her face as she looked down on him in the dim room. "You should be grateful I'm a Gryffindor, my dear snake."
"Oh and why is that?" he asked, meeting her amused eyes.
"Because this relationship of ours would never work if we weren't a Slytherin and a Gryffindor. This requires all of my Gryffindor bravery and all of your Slytherin cunning to be even theoretically possible. Two Slytherins would be too cautious try when it has to be so secret. And two Gryffindors would get caught. Hufflepuffs and Ravenclaws, well, they have no need for secret relationships do they? So, the fact remains that without me being 'such a Gryffindor' we wouldn't be here." She smirked triumphantly at him as she finished, and a wave of love, and lust, flooded through him. In one swift movement he rolled her onto her back and pinned her beneath him in the bed.
"Maybe you're right, I should be grateful. Just how grateful am I?" he whispered in her ear before nibbling on her earlobe.
She shivered in delight beneath him. "Very grateful indeed." She replied, before giving herself over to the sensations he created as he showed her just how grateful he was.
Later, as she once again lay in his arms, curled to his body and purring as his fingers traced patterns on her skin, he smiled softly to himself. He was more grateful than he could say for the witch in his arms, even if she was such a Gryffindor.
