Of course Duke didn't expect him to actually do any of that. He would never not have fun with other people because he was thinking about someone else...so obviously that would never be fair. And anyway, Marek was fun and good looking, he deserved to have his own bit of fun, and a lot of it. Duke just wasn't sure if he'd gone with any other guys or not since he was his first. Maybe it sparked a special interest? Or turned him off from it forever (though he highly doubted that).
"I'm not surprised." Grinning something wicked, Duke turned a little more and ran a hand over Marek's torso, right along the middle of his chest and stomach, where one might separate the two. Anyone could do something like that without it meaning more, but Duke was teetering on that line without caring. Leaning even more, he found himself another drink, just a shot, and tossed it back quickly.
