Undertail Smut [DISCONTINUED]

Fontcest [ Move it down the rhythm ] (1)

Fell Route !
Um.. I love you guys, but this is kind of angst... so... you've been warned I guess?

Papyrus played his favorite tune on his iPod whilst watching his little brother clean the upper part of their kitchen cupboard. Sans was wearing only apron, and he was bending his body onto the kitchen desk.

Papyrus smirks and licked his lips. He drinks his cup of bitter coffee. He doesn't mind. Because damn, watching Sans' ass is enough to make that coffee sweet.

Hey brother what you thinking ?

Leave that old record spinning.

You feel the rhythm going,

They call it lonely digging.

He stood up and spanks his little brother's arse.

"Ah!"

Sans turned around and glared.

"What was that for?"

Papyrus leaned into his ear and whispered.

"Doing this on purpose?"

Sans blushed and stuttered.

Papyrus' hands traveled from Sans' toe to thigh. Sans could feel his magic uncontrollably forming a sexual organ but couldn't do anything.

"N-No! Papyrus."

Let's end your time to lay low.

Your knees a-bending so,

It's time to get up and let go.

Sans was trembling under Papyrus' touch. Huffing every so often. Knees shaking and twitching. Papyrus' hand started to stroke his *whistle*

"Oh!"

Papyrus hummed the tune and licked Sans' shoulder. Leaving territorial marks all over his body.

Hey mama how's it going?

Can't see your body moving

Don't leave the party dying.

They call it lonely digging.

The room was filled with heat. Since it's cold outside. The window started to fog. Make the lights from town blurry.

Sans was drowning in ecstasy. Every inch of Sans was melting under the light of Papyrus' touch.
