This was usually the point where Damon was making some sort of pleased sound like a grunt or a moan, but Arik was quiet. It wasn't something Stefan was used to. He himself was always vocal in bed--which could sometimes be a problem--and he didn't think he'd ever had a lover that didn't display their pleasure with words or noises. He could still tell Arik was enjoying it though. Why wouldn't he?
As Stefan began to swallow down the man's length, he let out a muffled moan that broke the silence of the room for a short moment. He had to peel his eyes away from his master's handsome face and he closed the green orbs to focus on his work. He'd been doing this sort of thing for a century and a half and now he couldn't even remember the days when he used to gag on his brother's cock. It was simple to take Arik into his throat and bury his nose against the man's body while he held him there, another satisfied groan vibrating around his master's erection.
Maybe that would get a bit of sound out of the doctor.
