SansxAlphys or Swap PapyrusxUndyne, maybe? Their dynamic as lab partners could be interesting!
Underswap Papdyne
I’m normally not really into Alphys or Undyne shipped with anyone else (except pre-game as at least one of them ought to have had a partner before). But let’s do this anyway. It was still fun. I’ll do Stretch X Swap Undyne.
Papyrus grinned as he took up his ID-card,scanning it to get access to the True Lab. He went down the elevator, happy he fixedit just the day before so it went quietly. Well down, he sneaked through therooms until he came to the laboratory. Undyne was there, watching infascination as the chemicals reacted to one another.
He stepped into the Void, shortcutting tostraight behind her. Papyrus wrapped his arms around her waist without making asound. She jumped in surprise.
“hello, beautiful,” he whispered into her earfin,and she blushed slightly.
“P-Papyrus!” She broke free – Undyne wassurprisingly strong for someone who got so little physical exercise – andswatted his arm. “I-I’ve told you n-not to sneak up on m-me in the L-Lab. Or ata-all.”
“aw, c’mon,” He turned to the table, watchingthe equipment in curiosity. Pulling out his lab coat from his inventory, hepressed a kiss to her cheek. “what’re we doing today, boss?”
As Undyne explained, he watched her. It wasintriguing how she completely forgot to stutter when she got excited like this.In difference to Alphys’ chronic stuttering, Undyne’s was pure nervousness and habit and thereforenot always there.
“well then,” he nodded when she hadfinished. He put on his glasses – he had learnt the lesson to use them the hardway. Just because he didn’t have eyes that could get damaged didn’t mean itwouldn’t hurt like hell if he got any chemicals in his sockets – and smiled.“let’s get started.”
She gave Papyrus a grin, and bowed down. Undynewas roughly a head taller than him. Pressing a kiss to his teeth she nodded,something almost wild in her eyes.
He loved the fire in her eyes when she gotexcited about science or anime or something else.
It was fierce and passionate, and it was sheerbeauty.
He didn’t tell her this, though. Papyrus justkissed back before they started their work.
