Dean~
He kisses it slow, but passionate. Who knows, any day could be his last. He makes it meaning for you, savoring every piece of it.
Sam--
He kisses when he needs some loving, and if he feels out of it or you do. It always makes you or him laugh, knowing if makes either you feel better to know someones there.
Castiel
He loves kissing you, as he says 'you taste like honey'. Being the bee lover you both are, sometimes put lips of either of you lips and kiss the other.
Gabriel
He is a perverted angel, but he is you perverted angel. He likes teasing you through your kisses, like leaving half way. Then, when he isn't it usually gets heated, if your in the mood. Sometimes, it is just a make out.
Lucifer
He's Lucifer, what had you expected. But then again, you love it. He's the dominate one. It's the perfect mixture of Rough, but soft, and it isn't too passionate, to the point it gets heated. Although if he is in the mood, it will totally get heated.
Michael
It is usually him who starts the kiss. Its a slow kiss and loving. He loves you, and he's really a gentle being when it comes to you. He's has a soft spot for you. He only shows he sweetness with you, and most the sweet comes from kisses. Sometimes you kiss him the same way too.
