So many things are wrong at this moment, he's not sure where to start, but the fact he's just kissed his brother would possibly be a good one. Fortunately(?), it's not what he concentrates on.

What he does focus on: Ben's lips against his own, warm and soft and welcoming in a way he can't quite describe. It's nice, he thinks, sharing such an intimate moment with someone he cares so much about, and yet, his stomach and heart are simultaneously leaping for joy while freefalling into his stomach. This is only Ben's second kiss (his first with another male!) and here his lucky junkie ass is, getting to be the one to share it.

When Ben leans closer, the motion somewhat draws Klaus back to reality, makes him second-guess his initial decision to deepen the kiss further, so instead, he holds steady with the tentative, but sincere lip-lock before his brother fists his jacket. Hence why – despite his blatant reluctance – he breaks away after a moment, eyelids flickering like he's trying to blink through a daze, then focusing on Ben's face. He isn't certain what to say now, doesn't know if he could even manage the words if he did, though his thumbs do rub reassuring circles over the other male's cheeks.
