It always hurt at first like this, but Stefan was used to the pain by now--he'd had it a hell of a lot worse and more rough in his century and a half of living. The pain of the first push and thrusts only added to the pleasure for him and caused his body to hug Arik even tighter for a moment while he adjusted to being stretched open around his master's cock. His face twisted up, mouth hanging open with a gasp, eyes falling shut tight.
"Fuck," he groaned, hands wrapping around Arik's torso to dig short nails into his back. The doctor's thrusts were slow and even, and once Stefan had fully adjusted, he was moaning softly from underneath the man. Green eyes flickered open and glanced up at Arik, wanting to see the way the pleasure came over his features like it had earlier. But at the same time, he wanted another kiss--as many as he could get--so the older vampire relented, pulling his master down into another and parting his lips to find his tongue once again.
