They had mated for a long and glorious time, Sin's efforts were not wasted with this one. He'd continue his motions for quite a while, his inner desires beginning to satiate, though he was always up for more if the opportunity presented itself. After several long moments, he'd utter a final grunt through fur filled teeth, his form lying still atop hers as he released himself within. He knew by this time, she had been truthful in her words. So he had not held back as he had the first time they'd met. They'd remain like this for a moment, before finally he decided to release her scruff and extract himself from her form.
Returning to all four paws, he shook himself out as his loins calmed. Though the heat remained, he was satisfied for the moment. But he would not deny her another go if she so wished it. Padding to line himself with her shoulder, he half buried his nose within her neck fur as he inhaled her perfume. "You leave a man rather satisfied, and coming back for more I'm sure." He knew she would be a good mother, teaching his spawn the darker side of the world. The side that knew power, and dominance.
