Greg's voice was doubtful, hesitant as his hand paused. But his fingers reflexively squeezed at the warm space there, his own mind going back to their countless times at school. And it had been a long, long time since Greg had been intimate with anyone; he'd never fallen victim to his own weaknesses like others had who were locked up in prison. He'd made use of his own hands and that was it, no matter the mild temptations he had felt at times.
His physical need was there, but he didn't like the idea of fucking him; it just felt wrong on so many levels. It was like he was going to use Theo; and what if in the middle, he came to? Or worse yet, went babbly mad again?
Greg looked at the door, and lifted his wand, flicking a locking spell on it securely before he bent his head down to Theo's and kissed that devilish smile with a deep wet pull, "Roll over and I could show you, lover," he purred, wondering how he would be satisfied with just sucking Theo off. Greg worried a bit that once he started, he'd have a difficult time stopping but a blow job.....and his mind snapped back to the moment at hand.
"You know my mind, love. Let's get them out and play?" he said quietly, almost shaking himself now as he touched Theo's back end.
