Let me know now if you enjoyed these I love the aot ladies so much. If you wanna see more of them just let me know MY INBOX IS EMPTY. Feel free to send in some requests
Historia comes from a wealthy family. She LOVES showing you and Ymir with gifts.
Like she once bought you all animal onesie pajamas to wear for your movie night. Historia’s was a sheep, Ymir’s was a cow, and yours was a rat.
Ymir loves to pull the long pink tail attached to yours. Usually followed by a playful ‘Where do you think you’re going?’
When you all sit down for movie night. You and Ymir will both nuzzle into the warm wool like fabric covering Historia.
It’s not uncommon for you two to fall asleep there. Historia will smile at the two of you, running her fingers through your hair. She’ll plant on a small kiss against both of your heads and fall sleep there.
I hope you like nicknames cause Ymir as A LOT. It’s almost like she’s cat calling you whenever you’re within like a 100 meter radius of her.
Ymir was scared to take you to her home one day after school. She lives in a rather small trailer. She always feel a little self conscious when others are there so usually you’ll find her at Historia’s house.
She’ll be so soft for you, in a tender and intimate moment between the two of you when you tell her you don’t care about her being poor. You love her for her, faults and all.
Speaking of Ymir is super paranoid that you and Historia will both leave her someday cause she’s a bit of a shit at times. She’s convinced herself that she’s a horrible person and is dreading the day you two leave her.
Historia pulled you to the side one day and explained this to you, this issue Ymir has.
You then ran to go find Ymir. She was talking to Mikasa and you nearly tackled your tall Gf to the ground.
You grab her by the shoulders and made her look you in the eye.
“Ymir you’re a bitch! And I LOVE you so god damn much!”
You’re like John Mulaney when you talk about her to others.
“My wife is a bitch, and I like her so much”
Historia craves your love and support. She doesn’t get a whole lot of it back at home, she’s kinda just tossed to the side most of the time.
Ask her how her day was, and her eyes light up as she proceeds to go into great detail running her mouth a mile a minute. Your and Ymir will both just have these dumb love struck smiles across your faces as you watch your small blonde start talking with her hands. She does these big exaggerated motions as she gets to the climax of her story.
Most date nights are movie nights. You’ll usually play board games while you gossip every time Ymir suggests playing strip poker...you play it once.
You don’t like playing it, not because you get embarrassed about sitting half naked in Historia’s cold room (she tries to keep it warm but the whole house is just so cold in general) it’s because Ymir fucking cheats at poker.
Historia will get you all in a line while you do one another’s hair while you watch trashy reality TV.
Nicknames are pretty prevalent in this relationship.
Historia is :Princess, Queen, goddess, crystal, Krista(her middle name), Bunny, and Doll
Ymir is: Mommy, Daddy, YamYam, My favorite Bitch, Ms.Tall Dark and Handsome, Peasant, and Sleazy
You are: Baby, love, Honey, dear, darling, cutie, cuddle monster
It’s rare for Ymir to not spend the night with Historia or You.
Shes not vocal about it but Ymir NEEDS to be touching someone else at almost all times. So expect your fingers to be intertwined at all times.
Historia packs you lunch all the time and leaves little encouraging notes that help you get through the day.
Historia despite her small size is the commander of the bedroom. What she says goes and you and Ymir are just a couple of lowly servants dedicated to pamper and worship your goddess.
Ymir is a softy, she’s a rough dom or she’ll be strapped down and have her body explored by her two lovers. While she gazes into your eyes and pleads to cum.
All around it’s a very cute relationship, full of love and support, cherishing one another and devoting all your love to two lovers.
