Stefan felt her nails dig into him, the added strength of a vampire behind the movement, and groaned burying his face into her neck. He realised with a start that even though his fangs were fully extended and he was wound as tight as a spring, he didn't feel any desire to bite her. At least, not for her blood. It was like a weight had lifted inside him. He could just enjoy this without worrying, like had never been able to do before.
Stefan lifted his head again, looking down at her as she ran her fingers over his face. Her own dark eyes clouded to red as he watched and he gave a startled cry of pleasure as he felt her clench around him. "Fuck, Elena..." he moaned, his thrusts becoming jerky for a moment as he tried to compose himself. Even so soon, that had nearly pushed him over the edge. Still, once he had calmed down a bit, he increased his rhythm, pulling her leg up even higher around his waist as he pushed deeper into her, his movements harder, knowing he wouldn't hurt her now. He could let go and just thoroughly enjoy having sex with his girlfriend.
