I like to imagine that Levi can easily fall asleep to Mikasa singing a lullaby of some sort, like something her mom had sung to her as a child.

The Scouting Legion (Including the veterans who are very amused) is staring at Mikasa feeding sick!Levi. If someone uses this please tag me in it. I want to read it. (I accidentally submitted this in the ask box and now I feel like a complete idiot. Sorry.) 

I can imagine Mikasa being calm and somewhat discreet about wanting to start a family, even if it's painfully obvious especially in Levi's perspective. When Levi speaks up about wanting a child (she somehow persuaded him), her eyes light up and she can't stop smiling the entire day.

Levi is the only one (of his male friends) who has shaved "down there," so everyone who's seen his dick, (innocently in like the men's showers) automatically assumes he's filmed a lot of porn with Mikasa

I just like to think (and assume cause obviously this is pretty much canon) that Mikasa can wear the most horrific outfit and she'll look fucking amazing. One day she tests Levi (who gets turned on too easily by her) by wearing a sun dress and crocs, and pink extensions. The whole day he's blushing— not from embarrassment at what his girlfriend of five years is wearing, but because he has a painful and very noticeable dent in his pants. Later in bed, he whispers: "You can wear the hell out of those crocs."

Rivamika seems like the couple to fight for dominance while having sex. They basically tease each other (for a VERY long time) until one of them gives up and agrees to be submissive. But they sometimes have sex without the dom/sub thing because they’re horny and in love. ;)

MUSICIANS!AU where Levi and Mikasa have sex using a metronome. Each thrust or bounce matches with the clicks of it. ;)

Silly theory: Once Mikasa is as strong as Levi, a Rivamika arm wrestling match could theoretically last forever.

Headcanon: Mikasa and Levi decide to arm wrestle and everyone gets really into it, except that their arms don’t really move because they’re counterbalancing each other. It takes hours for one of them to falter and by then everyone has lost interest and/or gone to bed, or by the time one of them desperately needs to go to the bathroom, they decide to call it a draw.

I just like to think that Levi heard about those orgasms you get hypnosis from Hanji and him asking if he could do it to his lovely badass wife who wants to know where this is heading. After an hour Levi is on the floor exhausted because trying to figure out if Mikasa is actually going under his "spell" or just a really good actress. Mikasa is laughing hysterically at her defeated husband because he's trying so hard. They end up making love normally and crack up about it years later. “grandma, tell us some stories about you and grandpa!” “he tried to give me an orgasm using hypnosis but ended up lying on the floor”
