Dean thought he'd gone mad, really. Seamus took him by the shoulders - odd since he was taller, really - an then he was kissing him and it was... well, it was strange. And it was also like things were clicking and exploding behind his eyes, and before he could even respond, Seamus was pulling away.
Wasn't so bad. Dean felt like laughing, and that shrug was somehow like a challenge, and before he knew what he was doing his hand was strong on the back of Seamus' neck. "Not so bad..." he said, then pulled Seamus in against him, and said, "I can do better." Like a promise before he caught his best mate's mouth in a real kiss.
