Merlin had his head already buried under Dean's shirt and he was doing his best to alternate between kisses and teasing bites and blowing hot tickling air on Dean's skin in as unpredictable intervals as possible.

If it was possible, the fact that Dean would giggle and squirm like a little girl when tickled, made him all the more endearing to Merlin. Just ridiculously adorable.

Finally he popped his head up and leaned over Dean, looming over him with a small smile. "Oh man, I know," he murmured while lowering himself carefully to kiss Dean's neck. "Maybe there's something fundamentally wrong with me." Another kiss. "Because I don't feel ashamed at all." More kisses. "In my pitch black soul."
