Prompt: Ymir finds Historia's fanfiction collection and is very surprised at the content of them.
"Her body was on fire."
Historia stepped through the threshold of her and Ymir's apartment, setting the keys onto the table and sighing. It had been a long day at college and at her part-time job. All she wanted to do was get home, drink some hot tea, and read the compelling fanfiction she had recently discovered. It had been on her mind all day. She left off on a very se—
"She writhed underneath her lover's hand to only have her flank slapped with the riding crop! It was like a crackle of lightning, searing and stinging with sadistic pleasure!" Ymir called out from some room.
Why was she talking abo—No."Ymir!"
She heard something shift down the hall—a creak and blankets shuffling.
The bedroom!
Historia kicked off her shoes and ran on sore feet, ready to tackle her girlfriend.
"'More!' She screamed, earning her another spank, again and again, like the wicked little girl she was. Soon, her mistress pulled away, smirking something awful, and produced a gag. Oh! Oh my!" Ymir moaned the last words.
Historia barged into the bedroom to see Ymir in her lounge clothes, staring at her laptop, reading it before smiling and looking back down at the fanfiction she had accidentally and stupidly kept on her screen.
"'Mistress, punish me!'" Ymir cried before laughing and leaning back onto the pillows.
"Look at you," Ymir addressed Historia who froze up, embarrassed, "your face is all sorts of fifty shades of red."
"Y-Ymir! Tha-That was my laptop!"
"And that was your little kinky stuff I read, wasn't it? I didn't know you were into doing that. Think you're a bad girl?" Ymir asked, sitting up on her elbows and sizing up her girlfriend with intrigued eyes.
Oh, Ymir was wrong. She liked the idea of being dominant more than submissive, but she wasn't going to admit to that.
"C'mere," Ymir took the laptop off the bed, putting it on the side table and scrolling. She read a section before finally getting off the bed and going to Historia.
"I want to try something…" Ymir sauntered over to her, wrapping her arms around her midsection and carrying her onto the bed.
Oh God.
It was happening.
It was—but there was no bondage? No whips? Historia didn't want to do it unless they had some toys—
"Now," Ymir kept glancing back at the screen as she situated the two of them until they were in a very compromising position, "how the fuck is this pleasurable?!"
"Ymir!?"
"Look! I get you're into kinky shit, but what kind of position is this!? I can't even—"she began grinding her hips against Historia's as if to prove a point.
"Ymir! It's supposed to be erotic to the mind—"
"Yeah! But not if it doesn't make sense! I can see if I had a dick but I don't! It's just… It's just stupid! What is this!? The positions don't make sense!"
"Ymir," Historia rolled her eyes. Her mind and body was shot out of the fever it was about to go into.
"Seriously, if you want to do this sort of thing you got to get better positions. I'm going to break my back like this!"
That was the last time Historia ever left out her fanfiction to the critical eyes of Ymir.
