Ineffable reunion

Really?

You guessed wrong.

That was Aziraphale's intention. He pushed Crowley onto the bed, climbing on top of him. Crowley was about to speak when Aziraphale silenced him with a kiss, Crowley giving into it. The angel dragged his tongue along the serpent's sharp fang, just light enough not to bleed. He broke the kiss, "what were you saying, my dear?"

Crowley was stunned, his arms still spread out on the bed. "Angel, I-..."
"It's ok if you don't want to, Crowley."
"No! No, I want to. I'm just not sure if we should right now... you're still healing, Angel. I don't want you to get hurt. I want it to be such an amazing experience for the both of us, especially since I fucked up our first kiss like that, and it won't be so amazing for you if you're in pain." Crowley draped his arms around Aziraphale's neck, awaiting his response. "You're probably right. I suppose I'm just a tad ambitious after 6,000 years..." the angel smiled at the demon, a little embarrassed at his lack of self control. "We can most certainly kiss, and dare I mention that my tongue isn't actually fully revealed?" He smiled, his tongue sliding out, forked at the end and twice the length. "Oh, you shouldn't have done that." Aziraphale leaned in, kissing his demon again.

Crowley decided that the strain was too much on the angel's shoulders, so he rolled them over, sliding Aziraphale up against the headboard of the bed so that he was sitting. He sat on the angel's lap, hands on his shoulders. "I like this, Crow."
"..Crow?"
"You like it? I think it's cute."
"Only you get to call me that. Also, don't let anyone else hear you call me that."
"That can't hear me call you anything if your lips are on mine." Aziraphale held Crowley's hips. "Is that so?" Crowley leaned in, biting the angel's bottom lip lightly with one of his fangs. "Tease."
"Yeah, maybe."

Crowley kissed his Angel, passionately and roughly. He couldn't get close enough to him, even with their tongues twisted around each other. Slowly, the demon moved from his angel's mouth to his jawline, and down to his neck. "Can I... can I leave a mark?" He said in between kisses. "Make me bleed, dear. I want you to bite me. I want your fangs to leave your mark on my skin."
"You're sure?"
"Please."
Crowley sunk his fangs into the space where his neck and shoulder met. He tasted the warm blood, it wasn't like any blood he'd tasted before (mostly accidentally). It was unique, barely even tasting like blood. It tasted good? The bleeding stopped and Crowley sat up. Aziraphale was blushing hard, a hand covering his mouth. He looked up at the demon on top of him in awe. Crowley lifted the hand covering the angel's mouth. "Woah- no idea you'd be so into that." Crowley smirked, "what else aren't you telling me?"
"You'll have to figure that out yourself."
"You little shit."

Crowley rolled off of Aziraphale and sat next to him, admiring the mark he'd left. Aziraphale lifted his arm, inviting Crowley in. Crowley, of course, took that offer. He scooted in, resting his head on Aziraphale's chest and wrapping his legs around one of the angel's legs. "You're so warm, Angel." Aziraphale played with Crowley's hair, "is it true? That the humans started using 'Angel' as a term of endearment because of the way you call me 'Angel'?"
"Eh..  m'ybe. Dunno."
"Tired?"
"Yeah. Y'know what? I love you, Angel. And Satan, do I love your belly." Crowley tightened his grip on Aziraphale, completely latched on to him. "Oh dear, I love you too. My favorite part about your appearance, Crow, are your eyes. I love your eyes. They are the same eyes I fell in love with in Eden. I may have fallen in love with your eyes before I even fell in love with you." Aziraphale chuckled.

Crowley's voice barely above a whisper "... really?"
