Boom! Us Papyrus, Ut sans, and UF skelebros suddenly switch species with their human S/O. (Example: skelebro is now human and S/O is now a skeleton monster) what are their reactions?
Warning: Will and can get nsfw, but mostly PG-13
Btw, this ask reminds me of this fic. You should give it a read! Quick warning though, it’s explicit.
Woah…this is weird. There’s so much…skin??? Before he goes to test out his new body, Sans clumsily stumbles over to you to make sure you’re okay and……woah. You’re hot. Like seriously fucking hot. You’re flustered and shy about your new body, but all Sans wants to do is jump your bones, and he does. Afterwards, he takes you to Alphys to figure something out. But he’s in no rush, you’re absolutely breathtaking, plus he likes to explore his new body, though to be honest, he prefers being a skeleton. You humans have so much….meat, how do you even deal. After that though, you two are totally boning.
Shit, now that he has lungs, he can’t smoke to ease the edge off this whole situation. Well…maybe one won’t kill him. Just as he is about to light it, you walk in the room, completely naked and panicked, and his cigar just drops. Holy shit. You’re hot. You’re really hot, how is he supposed to handle this? But he pulls himself back together, while making flirtatious jokes and puns, and helps you get dressed. Once you’re presentable, Stretch tries to teleport to Undyne, before realizing that he can’t use magic anymore and gets the car with a pout. After the examination, Papy will spend hours memorizing every single one of your skeletal features.
…..Huh. Yeah, okay you’re panicking, but maybe you can get your human body back if he bones you. A lot. Multiple times. In many different positions. Please. Then again, you’re a skeleton now and might now know how to use magic to form the genitals, but if your skeletal body is anything like his, he can still figure something out. Please smack him in the head to return him to his senses. Red doesn’t want to ask Alphys for any favors, so he tries to figure out what’s going on himself and tries to fix it. It might take a while, but he thinks he can do it. It might help if you get in bed with him though~ You smack him again.
Fell is utterly, devotedly in love….with himself. I mean, check out his hot bod! Yeah he was hot as a skeleton before, but DAMN he’s still hot as a human, you’re going to need a fire extinguisher. Fell doesn’t barely spares a glance at you (yeah you’re beautiful my love, but have you seen my abs? I have abs!) He’s not sure if he wants to change back, but when he discovers the, ahem, bowel movement, and all the maintenance needed to keep a human body, Fell picks you up, rushes to Alphys, and demands her to fix him. It takes a while, but when she does, Fell is glad to have his old body back.
