At some point he goes in the kitchen to take something to drink along with a break from the overload of feelings; if his eyes get a little watery from seeing all those people he loves there just for his birthday well, blame it on the spicy food.
He feels a pair of arms slide around his waist and Cas' voice against his ear, sending shivers down his back.
"Overwhelmed?" he asks gently.
Dean turns a little to lock eyes with the angel.
"I'm becoming sentimental in my old age" he answers softly, half joking.
Cas laughs, eyes crinkling.
There's no reason to pretend with Cas, the angel knows him inside out after all. Dean knows he would never judge him.
"Is that so? that's okay" the angel presses his lips against his hard, taking his breath away.
Their tongues meet and Dean relaxes against him.
