Prompt: Daddy/Mommy Kink
Swapfell!Undyne & Reader
“...Wait a minute. You’re. Serious?” You stare out at Undyne from your sleeping bag on the floor of her cramped little living room.
The bipedal fish in question, with her severe hair bun and scarred eye was blushing a ruddy purple down to her gills. Amazing. This woman was 6 feet of teeth and scalpels for elbows and had the visage of a blushing schoolgirl.
You could hear the seams popping on the pillow she was clutching in her arms.
“Both the Queen and the Captain of the Royal Guard? Wow, you got high standards.” You say. Your eyebrows are so high right now.
“S-shut the fuck up.” She hisses at you, but oh hey look at that, she didn’t deny it at all.
You sit up, a shit eating grin spreading across your face.
“Wait, but Alphys told me that, like, she used to go up against the Queen when she was a runt to challenge her in a fight, and and, that she was personally trained by her. Oh my god. You’re in love with a mom and her daughter combo.”
She throws the pillow at you and you duck. It hits your shoulder with a hard thwack, but it's worth it.
“So, would this count as a mommy kink?”
“Oh my god!!! I’m gonna stab you with a scalpel!!!”
