Hi!! I was wondering, since it's pretty common for US!Pap, UF!Sans and SF!Pap to call their S/O's by cute pet names and such, how would they react if their S/O did the same for the first time? And they've never known S/O to use pet names for anyone, so it's just with them?
US!Papyrus: He’s taken by surprise at first, but you can tell that he enjoys it. The fact that you feel comfortable enough to use petnames with him, and with him of all people is really sweet. He especially likes to be called Dear, Hun and Hon/Honey. He’s not really about over the top petnames, he likes the simple ones. (If you searched for ‘’cute things to call your boyfriend’’ and just started listing off every name on there he’d probably die of laughter because he thinks most of them are stupid, but he appreciates irony. If you find the most ridiculous one there and keep using it on him he’ll never be able to stay mad at you)
UF!Sans: ‘‘ ’m sorry what didja just call me??’’ He acts like he doesn’t like it at first, but it’s just to cover up his shock. It’s always him throwing those words around left and right whenever he flirts with someone, and to him they don’t hold a lot of meaning. Until he started saying them to you. And now you’re the one making him blush and stutter from sweet words. But when they’re from you, he can tell that they mean something. They’re not empty, they’re full of love (as cliché as it sounds) He falls in love with you a little more, and he keeps his head in the crook of your neck to hide his goofy smile.
SF!Papyrus: Marry him. Please, he can’t even deal with how much he loves you right now. You’re so genuine and sweet and he just loves you so goddamn much. Call him whatever you want, he doesn’t care what it is. Everything sounds good coming from you and he has never felt so loved or loved someone as much as he loves you. He feels special and unique and he’ll do anything to make you feel the same way.
