Ben's quietly murmured yes was all the permission Klaus needed if hew as being honest, but the please made him huff out a soft breath of laughter, "Anything you want." He promised, because it was Ben - because they'd spent years always doing what Klaus wanted and now here he was with Ben real and whole again beside him and Klaus could not resist the chance to show him just how good being alive could be.
He pushed himself up just a little bit more, enough to urge Ben back, to hold himself up over him as he pressed Ben down into the mattress and kissed him once more, hungry and deep before he was pulling back and mouthing his way along Ben's jaw, and down his neck as he fit his body between Ben's legs.
With Bill Klaus liked to watch, to be impressed by little shows of magic and talent, but here with Ben he wanted to take and take and take. And it started just like this.
"I can't believe we haven't done this yet," He said between laying open mouthed kisses along the line of Ben's throat, he should leave a mark there, purely because he could - to see it later and know that he'd put it there. That Ben was his and the lingering mark would be proof of it. As if the way they moved through the world side by side was not proof enough.
But it was never enough, not since Ben had found his way back to the land of the living and Klaus intended to show him how much more they could have now.
