" Your soul is so beautiful, Sam." whispers Castiel "And so is your body."
His lips are howling just above Sam's face, his breath hot against his skin, eyes burning with intent. He has Sam just where as he should be - naked and whimpering with need, hands tied by soft rope to the bed.
"Makes me want to worship it."
"Yes, Cas... anything." this broken cry is all that Sam is capable of at this moment.
Castiel smirks and starts to move to the lover parts of Sam's perfect, toned body.
First his mouth moves along his elegant swan-like neck, feeling the movement of larynx and sweet/salt taste of sweat. That's how Sam's desperation and passion tastes like.
He nips at his collarbone, enjoying contrasting sensation of delicate skin and tough bone beneath. His hands smoothes on Sam's sides, applying more pressure on his ribs. Sam's hisses and tenses a little, ticklish but too lost in Castiel's touch and own pleasure to really mind.
Cas hums with contentment, knowing that those ribs bear his own marking. Enochian signs didn't have sexual meaning when he carved them, but now he finds that he likes Sam being permanently stamped. He belongs to Castiel and have to know it. Cas sucks at Sam's chest, hard and with hint of teethes, to leave a mark at the outside of his body as well.
Then he spend considerable amount of time, wondering at Sam's navel. It's a proof of Sam's birth, of the miracle that created this extraordinary, marvelous human being. Cas loves it. He gently teases it with fingers, head laying on Sam's abdomen and finally sticks his tongue in it.
"Cas..." he hears Sam's pleads "Cas, I beg you..."
Cas would like to spend eternity exploring every millimeter of Sam's body, but he can't refuse him anything. Not when Sam's eyes are big and soft and focused on Castiel's face with immeasurable trust.
He takes to hand Sam's aching member and starts with loose grip and slow strokes, enough to bring at the edge of pleasure but not enough to give him relief. Gradually, he faster his movements and increase the pressure.
He looks at Sam's face, at his trembling muscles and catalogs every sound, every whisper, every expression. Even if he have seen this a hundred times, it's still takes his breath away.
Feeling like he could explode with overwhelming emotions, he lowers his mouth to head of Sam's penis and places one loving, tender kiss.
It's all it takes. Sam cries his name and shoots his load at Castiel's face, eyes closed and body in arc.
When he comes to his senses his sees Castiel who takes a little of white mess on his finger and licks it deliberately slow. Sam laugh softly and pull on the ropes that still holds him in one place.
"If you take this off..." he says in low, seducing voice "I'll worship your body too."
And Cas doesn't complain about that plan.
