Sam's been a member of the club for a while, having joined when he landed his first job with a firm after law school. Something he'd only been able to do because one of the other lawyers knew what somebody like him would be able to make. Sam's always been grateful to Gabriel for that, because the club allows him an outlet that he wouldn't normally have. Something he desperately needs sometimes.

It doesn't matter here that he doesn't have a regular sub. There are plenty of subs who have never had a regular dom, either, and are happy to have a chance to play with somebody who knows what they're doing. Though he'd be lying if he said he'd never watched Castiel in the club and wondered. He doubts there's a dom in the building who hasn't wondered.

Sam takes the offered hand, shaking it firmly. To be honest, he's a bit surprised to be approached, all things considered. "Mr. Milton." He's not entirely certain how to react. "I suppose...well. A private room might be best right now."
