Oh Merlin, Duke was already thinking of that and all the other positions they could be in throughout his flat. Obviously right there on the balcony would be most convenient. Knowing that wasn't probably, however, meant he needed to stop thinking about it.

A sloppy grin echoed Marek's and Duke shrugged, resting his forearm on Marek's shoulder so that his fingers could play with the hair on the back of his head. "Hn. I'd like to say yes, but I have no idea. I think I'll at least remember you in some sense," he shrugged. It was true that he wanted Marek. He wanted to shag him, to kiss him, lie in bed with him.
There were definitely more than just sexual feelings; Duke genuinely liked Marek. He was charming in a dorky way, charismatic, open to a lot of things. What wasn't there to like? In a lot of ways, Duke realized, Marek reminded him of himself.
