Kurt hadn't felt obligated. Bert was.. just really attractive. He wasn't used to just reaching out and touching people, at least not in a sexual manner.

His breath catches though when Bert decides to up the ante. Kurt's black briefs were barely containing him. Once Bert was free of his pants, Kurt looks at his face a moment before braving the chance to touch him.

"You're really hot," Kurt admires. He runs his fingers along Bert's stomach and chest.
