Quentin's obvious eagerness works to soothe any nerves Kyle has about this (at least to him) rather significant first. He moves as slow as he can, stopping when he feels Quentin exhale against his neck.

"Okay," he murmurs aloud in response to that mental request. "Just... a second. Give our bodies a second."

Partially this is because he doesn't want to cum too soon, and partially because his own memory is of wanting time to adjust.

Slowly, he rolls his hips forward, mouth hanging open slightly, until he's buried as deep as he can be.

"Oh, Quentin. You feel amazing. Can I move?"
