A/N: Just a heads up, most of the prompts written in this book will take place in a modern AU setting. Since in my personal opinion, the canon AOT universe is not a good universe to have relationships in.

Don't worry though, there will still be chapters written in the canon universe. But most of them will take place in a modern setting.

WARNING: Some Semi-NSFW bits in some parts. Though, they are just subtle implications and there's nothing too explicit.

-------------------------------------------

Mikasa Ackerman

-Okay first of all, you're seductive as fuck.

-If you flirt with her in any way, she will blush so hard, she won't even look at you properly.

- "Mikasaaa~" you'd tease, "Are you getting flustered because of me?"

-She's pretty quiet in response to your teasing, but don't let her shyness fool you. She can also be possessive as fuck.

-Since you're quite the piece of eye candy, Mikasa always has an arm around your waist wherever you go. Her eyes piercing through anyone's soul if they dare look at you wrong. 

- "Mikasa...you're crushing my waist."

- "Sorry, I just want people to know what's mine."

-You two are the definition of a sexy power couple dynamic.

-Sometimes when Mikasa get's too jealous over people staring, she breaks her shy mold and shows you just how possessive she could be. Which can lead to some...interesting punishment scenarios.

Annie Leonhart

-Unlike Mikasa, she's quite amused by your flirtatious remarks and teasing. Not shy at all, even when you touch her.

-Plays along with your flirts. Sometimes she even manages to fluster you.

- "Cocky aren't we? I bet I can wipe that smug grin off your face in the bedroom."

-You two are an even match. Even though Annie hardly ever flirts back, she just smirks at your words and drinks them all in. Seeming to take pride in your attempts to fluster her.

-Confidence is key. And with Annie, she's pretty confident in how much she can compose herself with you around.

- "Aww, is that all you have for me?"

- "Shut up Annie."

- "Now now S/O, that's no way to talk to your mistress..."

Ymir

-Has trouble accepting the fact that you top most of the time.

-She just can't comprehend how seductive you are, it's insane.

- "Do you really have to flirt with me? Right here, right now?"

- "You know how I am, Ymir."

-Get's flustered easily by your teasing, but tries not to show it. (Don't burst her ego please)

-Can get a teensy bit jealous if you subconsciously flirt with other people. But she knows that it's just your personality. 

-Ymir is probably one of those "I'll punch you in the face if you look at my girlfriend wrong" types of girlfriends.

-She's not as possessive as Mikasa, but she will show other people that you're taken.

-Hickies.

Historia Reiss

-She get's both flustered and excited whenever you flirt with her. As she finds your sultry comments to be extremely hot.

-May even flirt back if she finds the right comeback. 

- "So what if I'm short? I'm better on my knees anyway...~"

-Note that she only flirts back if you two are alone together in private.

-Can't concentrate if you flirt with her in public. She get's so red, she will be quiet for the remainder of your outing. 

-When you two are alone again, she starts scolding you on how embarrassed she was to have everyone hear in on your conversation.

- "S/O, you can't just ask what kind of panties I'm wearing in front of other people!"

- "...I'm guessing you don't wanna do it tonight then?"

- "I didn't say that."

Hange Zoe

- "You're hot. I'm hot. Let's fuck."

-Embraces your seduction whole-heartedly. Any excuse to touch her girlfriend is good enough for her. 

-Will flirt back if she can. Doesn't matter if you're in public or private.

- "Ehehe, let's test your stamina, S/O. Shall we?"

-I didn't say they were good flirts.

-Can come off as sort of creepy to your other friends, but you love her so you find her attempts at flirting to be rather cute.

- "Hange darling, you need to improve a little bit on your flirtation skills."

- "What? I thought you loved my oral speeches."

-You choked. 

-Okay that was a good one.

Sasha Braus

-A bit shyer when it came to your teasing, but she smiles instead of getting flustered.

- "Yep, that's my girlfriend. That seductive piece of "Iwannafuckher" is my girlfriend!"

-Very proud to have you. She shows you off to all her friends and basks in all their envy.

- "What the hell Sasha. How'd you snag such a hot girl?" Connie would complain.

- "Simple. I just showed her how good I could eat."

- "How does that-- OH."

-She'll blush if you eat a piece of food seductively, and silently wish that she was that piece of food.

- "Sasha, why are you staring at her so intensely..."

- "You don't understand how much I want to be that cherry right now..."

Pieck Finger 

-She tends to blush whenever you flirt with her. But instead of getting too flustered, she just flirts back nonchalantly. 

- "My ass looks hot? Well, darling, you should see yours. Oh wait, you can't. 'Cause only I can see it."

-Will wink at you from across the room if others are present.

-If you respond with a subtle lip bite, she'll quirk up an eyebrow in interest and continue flirting with body language in secret.

-Pieck has a tendency to touch you in suggestive ways if you're okay with it. It's a contrast to your vocal flirting, as her love language is often physical touch.

-She can get a little handsy with you. Especially since she's kind of into PDA.

- "Getting a little frisky there, huh Pieck?" you'd whisper, feeling her hands slide down your waist.

- "Don't lie, you like a little risk." she'd tease back.

Yelena

-Stoic. As. Fuck.

-No matter how hard you try, you just cannot fluster her. 

-She finds it amusing whenever you pout in frustration, so she leans down to your height to deliver her flirtatious remarks. 

- "You're such a brat, you know that? Don't worry though, I'm sure I can fix that..."

-Immune to your seductive voice. Sure she'll react with interest, but she won't openly look flustered for the sake of her own pride.

- "Yelena, why don't you blush or anything whenever I flirt with you?"

- "Because I'd rather see you blush, princess..."

-S̶u̶g̶a̶r̶ ̶M̶o̶m̶m̶y̶ ̶Y̶e̶l̶e̶n̶a̶?̶

-Yeah, you're ineffective against this one. Have fun getting creative on how to fluster her.
