Before Eames, Arthur would have sworn that he was not into public/semi public sex like this. But Eames was his, and Arthur knew who he belonged to. After the life that they've led thus far, he was going to take the intimate moments when they can. After all, who knows when the next moment may be their last. He wasn't going to spend his life filled with regret.

"So you say," he gives him a little smirk before groaning low at the slap. Only wearing his underwear, he's unable to hide the way his body reacts to Eames' hand on him. His nipples felt tight and he was hard, he bites down on his lip as he looks the other man over slowly.

"I want your mouth," he says and slides his hand over Eames' neck. Given the option of waiting and having Eames' mouth on him now, he knew what he would choose. Still, he didn't mind playing Eames' games either.
