Stiles sighs into the gentle kiss, returning it slowly, languidly, feeling no need to rush anymore. He lets their tongues slide lazily together as he tastes Peter, gingerly deepening the kiss.

When he pulls back he's smiling softly up at him, leaning in to nuzzle at his face, hoping to convey what he's feeling without words. Sometimes they don't need them.
