Fantasies
Natsu's light snoring filled the otherwise silent room.
Gray was lying beside the fire mage, still, observing. By the corner of his eye he could see the small glass vial that stood on the bedside table. Gray gulped. Scooted slightly closer to Natsu.
The fire mage remained oblivious.
Gray sighed. His thoughts took him to the conversation that had started the whole situation.
"I wouldn't mind trying it." Natsu told a flabbergasted Gray. He shrugged. "I trust that you wouldn't do anything too over the top, no?"
"Of course not." Gray cut in sharply. "But… are you sure? I didn't mean that we had to try it. It's just a dumb fantasy I have anyway."
"I don't mind. Really." Natsu said seriously. "The way I see it, I help you with this one," Natsu winked cheekily, "and you help me next time."
"Do you mean…?"
"Of course. Next time we try out a fantasy of mine!" Natsu laughed. "Now… I think that we might need some help with this, I'm a bit of a light sleeper – as you know."
"I think that we can take care of that." Gray conceded.
And they did.
Natsu had drank the sea-green draught they'd gotten from the guild and here they were.
Almost one hour had passed since Natsu had drank the draught and fallen asleep and Gray stood still and unmoving beside him.
Finally Gray was only separated from Natsu by scant centimetres and curiosity had the best of him. With his hand he reached towards Natsu's chest, placing it right above the fire mage's heart. The rise and fall of the chest as well as the steady beat of Natsu's heart reassured Gray.
And suddenly, as if a switch had been lit, it was time to have fun.
Gray threw the blankets off Natsu, his eyes feasting on the delectable body of the dragonslayer. It was beckoning, calling for Gray to do as he pleased on the golden skin. Gray began by brushing his lips against the slightly bruised knuckles of Natsu's hand, manoeuvring the hand so that he could lay a kiss on the palm. He licked and suckled at the inside of the wrist, taking his time to leave a bruise – a mark – there. Then he followed the path to the arm, reaching the shoulder and stopping at the collarbone. There he laid a series of more marks, though they were smaller.
