The sight of tears on Dean's face nearly broke Seamus's heart and for a breathless moment, he thought this was it - that they was over. But suddenly, he was in Dean's arms, Dean's mouth so insistent on his and Seamus letting out a shuddering sound of relief. Seamus responded immediately, hands curled in the front of Dean's shirt as he let Dean pour everything into that kiss.
Seamus felt bereft when the kiss ended, and had never felt so inconvenienced by the need to breathe than he did just then. It was worth it, though, so very worth it to hear what Dean had to say. He'd waited such a long time to hear those words and his breath left him in a rush, the threat of tears making his voice thick. "God, I love you, too, Dean. So much I didn't even know until I almost lost you."
