Sans blew a ring of smoke into the icy Snowdin air. The lights in his eyes flickered out for a moment, and he leant back against Papyrus' shed. God, he was so tired. His letterbox was overflowing with bills and complaints from various citizens; it was a chore keeping it from Papyrus.

Speaking of his brother...

"SANS! WHY ARE YOU SMOKING OUTSIDE INSTEAD OF APOLOGISING TO ME?!"

"hey, bro."

"EUGH, YOU KNOW WHAT? FUCK YOU SANS! FUCK YOU AND YOUR LAZY WAYS!"

"hey, hey!"

"I WAS BEGGING YOU, ON MY KNEES, AND YOU LEFT ME! YOU LEFT ME WHEN I NEEDED YOU THE MOST!"

"jesus fucking christ. whatever. i thought you were into that kinda thing."

"I MOST DEFINITELY AM NOT!"

"fuck you, papyrus."

"FINALLY."

"what?"

"GO ON. SUCK IT."

Sans was so peeved. He couldn't believe he was doing this. But one short glance at his brother's face, commanding and full of anger, made his cheeks flush blue, and suddenly he fell onto Papyrus and started tearing off his shorts.

Papyrus's cock was huge, throbbing and orange. The very sight of it made Sans' mouth water, and his eyes widened as it thrust towards him.

"c-can i..."

"GO AHEAD," smiled Papyrus, his expression softening as Sans leant forward to plant a gentle kiss on the now-moist dick.

Suddenly it was crammed into his mouth, and Papyrus tilted his head back and let out a "NYEH!" of pleasure.

He began to skullfuck the smaller skeleton, making him choke as a light blue tongue formed and wrapped itself around the intrusion.

Somehow, the couple waddled behind the shed and out of plain sight, where they continued to fuck until the streets were empty.

It was well past midnight by the time Sans pulled back with a lewd "pop."

"WOWIE..." whispered Papyrus, as childlike as Sans thought of him.

"THAT WAS... AMAZING..."

"heh." Sans was blushing deeper than a blueberry. "you're welcome."
