Characters: US Sans, US Grillby
It was a lovely evening. It was no wind, relatively warm – even though cold would not be of any issue this time – and the night sky was completely cloudless. It stretched endlessly, past the horizon, stars splattered over it. Sans marvelled in how gorgeous it was. The moon was not out tonight, which was making the stars shine brighter than ever. The stars in his own eyes grew bigger as he counted the constellations he could find whilst they walked toward the hill they were going to spend the coming hours.
”I see your amazement over them haven’t shrunk, my sweet.”
The warm voice woke Sans out of his haze, and he turned to the fire elemental who accompanied him here tonight. Grillby’s flames was dimmed so they wouldn’t make their night vision worse than necessary, just for Sans’ sake. The thought made him smile even more. Grillby did not much like to dim his glowing flare, and normally there was few things he adored more than the beaming light and warmth they gave away, but when watching the stars it was bound to get difficult if they were as bright as they usual were.
”Of course not.” He breathed, voice much quieter than normal. Looking up at the sky once more his eyelights looked more like explosions than stars. ”How could it? The stars are infinite, there are so many more than even I can count. Who knows what could be up there? Perhaps someone lives out there, watching us like we are watching them. And even if not, they’re so beautiful.”
”Not half as beautiful as you, firefly.”
The line was delivered quickly, smoothly, and with what sounded like completely sincerity. Sans fought the blue blush lightning up his face, making his boyfriend chuckle. Grillby couldn’t just say things like that, and Sans told him that.
The elemental laughed and kissed his skull. It was a warm sound – like all his sounds around the skeleton – and he straightened out his turqoise suit. Not even stargazing on the grass had been enough to get him to change from suits to something more comfortable.
Nothing more was said, or needed to be said, as they in comfortable silence came to the place they had decided on earlier the same day. Sans put out the picnic blanket and his boyfriend pulled out the food basket from his inventory. Together they unpacked and put out everything on its correct places before taking place on it, close together.
The basket had all of both their favourite things – except mexican, as Grillby had decided they could not eat mexican every single day. Greasy burgers, fruity drinks, onion rings, deep-fried fruits of different kinds. None of that sugary stuff Papy liked. Sans couldn’t stand the sweet (and Papy couldn’t stand the grease, which was one of the reasons they mostly ate tacos and other mexican foods at home).
Sans sipped at his drink; some might think it an odd mix with all this greasy bar food and then these luxurious drinks, but it worked well and Sans didn’t really get the chance to drink alcoholic beverages too often since Grillby more or less was the only one who remembered that he most certainly was old enough to drink – not even Papy seemed to do that, and Sans raised him on his own. It was very frustrating, but anything for Papyrus’ mental health. So he had to take the chance when with his boyfriend.
”IT’S DELICIOUS AS ALWAYS, GRILLBZ,” he commented, pressing a skeleton kiss to the other’s cheek. ”STARS, I LOVE YOU.”
”I love you as well, Sans.” Grillby’s flames burned a little hotter, even though they did not get brighter. Sans laughed quietly. He knew the other well enough to know that the other was blushing, and he loved it. Grillby almost never lost his calm, the flame was extremely smooth and graceful, but whenever Sans said those three words he always grew hotter. In both senses. He chuckled at the pun. And then there was one more way he knew of to make the other blush.
”HEY, GRILLBY.” He waited for the other to turn to look at him before he let his grin grow wider. ”IS IT HOT OUT HERE, OR IS IT JUST YOU?”
”I REALLY LIKE YOUR FLAMEBOYANT CLOTHES.”
”WE ALWAYS TELL CHILDREN NOT TO PLAY WITH FIRE, BUT I THINK I’D LIKE TO DO THAT ONCE WE GET HOME.”
Especially the last one had the other hiding his face in his hands, in both embarrassment and annoyance, and Sans was almost rolling on the ground with laughter. Complimenting with puns always worked.
Half an hour later they had almost finished their food, and Sans had showed the other all his favourite constellations when light dots showed up at the foot of the hill.
”LOOK!” he said excitedly. ”I THINK IT’S STARTING!”
True enough, within a minute the first one was heard, and soon the sky was filled with explosions of light in different colours.
”I love fireworks.” Grillby sighed. Sans had to agree. These light shows were one of the best things about the Surface.
”YEAH,” he sighed, smiling. ”THEY’RE VERY PRETTY, AREN’T THEY? ALMOST AS RADIANT AS YOU.”
”Oh, firefly.” He could hear the other’s affection and it made his soul glow in pure happiness.
They cuddled close together while watching the splendid display in front of them, not saying much. Sans pressed himself closer to the other, basking in the comfortable heat. After what felt like both hours and minutes at the same time the fireworks eventually stopped, but neither of them felt like moving.
”I COULD TELEPORT US HOME,” Sans noted hesitantly, sitting up, but Grillby broke him off before he could continue.
”I say we stay here tonight. No one would dare to rob us, and I can have some firelings take on guard duty for safety’s sake, if you want. What do you say, beloved?”
Sans sighed happily and leaned down on the fire elemental once more. He couldn’t help but smile, and the stars in his eyes changed to hearts.
