He very nearly told him he wasn't about to coddle him for being a virgin, but it was the wrong thing to say to reach his goals. If this had just been about tonight he would have, but he wanted Louis coming back. For that to happen, he could play nice for an evening.
"Of course," he said, taking his hand and bringing him to the bed. "You have nothing to worry about." Tonight at least. In the future... well then he'd like that too.
Pushing Louis back on the bed, Julius kissed him again, once more rubbing their cocks together. With his hand on Louis, he guided him, made him stroke the both of them together as he silently cast a lubrication spell.
He didn't need words, the sounds Louis were making was quite enough to tell him what he needed to know. Pulling back, he used his fingers to prep him, only as long as he had to, before slowly starting to thrust into him. "Keep stroking yourself," he ordered hoarsely. Partly because it would help, partly because it was hot to watch and partly because he didn't want Louis getting used to him doing things for him. He would know to be grateful for the times he did.
He moved slower than he wanted to, taking his time before he was finally sheeted completely inside him. With a deep satisfying groan, he pulled out and sank back in, taking pleasure with every inch.
