When Petra emerged from her titan form the first time, the only thing Levi thought about was her safety. Sure, they'd seen that Eren was perfectly fine, albeit a bit knocked out of it. But the idea of humans controlling titans is still pretty new to their own little world. As Petra's captain, of course he'd do whatever he can to protect his subordinates.

They tested out her abilities in the limited time they have until the next expedition. Hange, the mad bitch that they are, would be the one doing and leading the experiments while his squad oversees. Frankly, him and the three other guys think it's more to protect Petra from Hange's crazy ideas.

So, it was the same as usual. As far as usual can get when it comes to the Survey Corps, that is. Petra was still in his team and surprisingly, nothing changed in their relationship as captain and subordinate.

Everything only shifted when he'd seen her in action during her first expedition as a titan shifter.

He honestly thinks that her titan form is ugly as fuck. It was even uglier than Yeager's. However, seeing the fire in its eyes, in her amber eyes that is just so Petra had left him a little bit awestruck. Her titan has the same ginger hair and he shouldn't be thinking this, because he's looking at a titan, but is it shining when the light hits her tresses? He feels his mouth go dry as Petra's titan shields an injured scout from two abnormals, before making a move to kill them by biting off their napes.

She lands back on the ground, re-assembling herself in their usual scouting formation.

Fuck.

"Levi? Are you okay?" Erwin pipes up once they're all in the clear.

"What the fuck are you talking about, Erwin?"

Erwin, that bastard, only gives him a slow smirk in return.

"I hope that won't be much of a hindrance then," Erwin says, gesturing down. Levi glances down and only realizes now why his pants have started to tighten. The fact that he's currently riding a horse isn't doing him any favors.

There was this one time when Hange wanted to test how long the younger girl can retain her titan form and they found out that she can go on for months. He'd have to admit that he misses actually seeing Petra's face but even Levi found her titan's strength impressive.

Until she started crawling around in her human form.

He finds her crawling one afternoon and Levi feels that familiar heat flare up inside him as he takes in the curve of her back and ass. His eyes would sometimes stray there during trainings but he'd never expected her backside to be this round and full. The fact that she's currently in a dress that reaches just below her knee is only making this worse. He swallows when he sees a hint of exposed skin of her thigh and if he could bunch up her dress further, it would be so easy to just take her right now.

Levi's hand twitches, and he repeatedly needed to remind himself that touching his subordinate is considered harassment.

"What the fuck are you doing, Petra!?"

"Oh, hi captain!" Petra flushes in embarrassment, trying to push herself up against the wall but fails every time. She almost hit her head once, if Levi hadn't stepped in and helped her up himself.

"I'm sorry," She says, clinging to him. Levi, mortified that another inch closer would mean she'll feel the rising enthusiasm below his belt, tries to discreetly move his lower part away. "I didn't know this is a side effect of being in my titan form for too long. I'm actually on my way to tell Hange about it."

"Side effect?"

Petra only blushes deeper. "My body... might've forgotten how to walk properly since I've been on all fours for so long."

Levi can feel his brain short-circuiting when she said the words all fours. His brain started supplying him with an image of her on all fours in his own bedroom floor, of how he would bend her over and make her suck his-

"Hey Petra!" Thank fucking god. He'd never been so glad to have Hange around. "Gunther said you were coming to see me?"

Wanting to get everything over with completely (so he can run to his room and deal with his rising erection), he hoisted Petra up in his arms instead, leading to her wrapping her own arms around his neck. A blush tinges her soft round cheeks and he tries to avoid looking down at her, knowing that she's staring up at him in wonder.

He'd noticed this with Petra whenever they're physically close together, of how she'd be in a sort of trance whenever he'd subconsciously tuck a strand behind her ear or when she'd lean down to set his tea on his office table and he really shouldn't be thinking of this right now when he was just thinking of fucking her if Hange hadn't barged in.

Once she's settled in Hange's lab, Four Eyes took that moment to turn to Levi.

"Now you know how I feel whenever I see titans," Hange says.

"What." Horror starts to rise in Levi's chest when he realizes their implication, but only his disgust shines through his face.

"What?" Hange answers back, acting as if what they just said was a normal statement.

That same afternoon, Levi demanded from the medical team that they better provide him a crutch right fucking now or he won't be responsible for the injuries he'll be causing on the inhabitants of the room.

He hurriedly gives it to Petra, harshly ordering her that she is not to crawl around like that ever again for the sake of her dignity. Deep down, he knows it's to save his.

---

He tried to avoid being alone with Petra in her titan form in the coming months. Actually, he avoided being alone with her completely, even when she's out of her titan. But it's a Friday night and all the other scouts have been given time off, with some of them already packed up to go home for the weekend to see their family.

Petra, on the other hand, had no choice but to stay until further notice. She could barely leave the building unless either Levi, Eld, Gunther or Oluo is with her.

He sees her alone right now outside since Hange wanted to test if Petra can stay up all night in this form. The sun will rise up in a few hours, and he thinks this is more than enough time to indulge Four-Eyes in their curiosity.

"Captain?" It always catches him off guard whenever Petra speaks in her titan form. Her voice was so different from the sweet and cheerful tone he'd gotten used to greeting him in the morning.

"Couldn't sleep."

She's currently lying down, hands tucked under her titan's chin and it endearingly reminds him of a ginger cat curled up and poised to sleep. He noticed how Petra's eyes reveals just how bored she is, staring only straight ahead.

"Aren't you tired?" Levi asks, leaning his body against the side of Petra's titan form. Feeling the titan's bare skin almost made him flinch because he knows it's Petra. He shouldn't be thinking of his subordinate naked right now but her titan form isn't helping at all.

"Levi... are you actually getting attracted to a titan?" Erwin had asked him once, amusement coloring the blonde man's features, when he caught Levi staring at Petra's titan form during one of her experiments with Hange. "Maybe I shouldn't have allowed you to be around Hange too much."

"Are you on some drugs, Erwin?" Levi snaps, but can't help the thumping in his chest and the rising panic because of course Erwin would catch on eventually. "Are you getting too smart that that brain of yours actually rotted and died in a shithole?"

Petra only shakes her head. "I'm all good, captain. Besides, Hange tells me I can take the day off to rest tomorrow. Still can't leave the barracks though."

Levi tries to avoid cringing at hearing her titan's voice. He doesn't think he'll ever get used to it. "Can you not talk to me while you're using that voice? Get out of there." He orders.

Petra, always obedient and willing to please her captain, did get out of her titan. She struggled with detaching her hands as usual and Levi sighs, making a move to climb up and help her.

Before he gets the chance to do so, Petra was able to pull herself out abruptly but the force was enough to send her flying to the ground.

Levi's reflexes was fast enough to try and cushion her fall but the angle wasn't right for him to catch her properly, and Petra ends up landing on top of Levi and both of the groan at the impact.

Levi thinks that his erection must really hate him. It already betrayed him once during a fucking expedition. It's rising again now as Petra shuffles around in an attempt to stand up, muttering a string of sorry captain! and I didn't mean to, her every action brushing further against his dick.

"Stop it, Petra!" He shouts, panic almost tinging his voice. Petra freezes at his voice and Levi thinks that maybe he shouldn't have asked her to stop moving because now, his dick is directly against her thigh and she'll eventually feel everything.

He watches as confusion passes through Petra's face, before it shifts to shock when she finally realizes what was pressing against her thigh, eventually settling on a coy smile.

They stared at each other a little longer before this minx actually found the courage to intentionally press her thigh down further. Levi finally allows his pent up lust and frustration to blow over, growling as he grabs Petra's hair to pull her down for a bruising kiss.

When Petra mentioned that she's getting a whole Saturday off to rest, he's pretty sure this wasn't how Hange instructed the younger girl to spend her day.

He already came once after she enthusiastically sucked him off. He could only watch in a daze as Petra took him as far as she could, almost intentionally choking herself on his own cock. He's surprised at how much of an absolute freak Petra is, insisting that she's going to swallow every last drop of him even when he tried to push her away for her sake.

Now, she's settling herself on his bed, on all fours, and Levi's pretty sure he's going to die before this day ends. He palms her ass, giving a squeeze as he feels her up, before kneeling behind her to deliver hot kisses down her spine. Petra shivers when he pulls on her hips to draw her closer.

"I wanted to rail you so bad the past few weeks, Petra." He whisper against her skin, hand trailing down to start playing with her clit. "Fuck, your experiments with Four Eyes only made it worse."

"Take me like this then, captain." She says in the filthiest voice she could muster, grinding her ass up firmly against his clothed erection and opening her legs further for him. From the naughty smirk that she's giving him, Levi finally realizes that she'd already known just what has been running on his mind the past few weeks.

He can see her core glistening, half from when he'd fucked her with his tongue earlier on and half from her eagerness and anticipation to have him inside her as soon as possible.

He tears his underwear away, wasting no time in breaching her wet core. Petra moans wantonly, curving her lower back further so she can push her ass up to pull him inside of her more.

How can someone who sounds and looks and acts so sweet be such a fucking slut in bed? he thinks in a daze as he starts pounding inside her.

It was a tight fit and Petra grabs one of his hands to push his palm up against her breast. Levi was all too eager to indulge in her fantasies, thumbing down her erect nipple and squeezing as he gives a hard thrust.

When he hits the spot inside her just right, that's when they both fasten their pace. Petra braced her arms against the sheets, head falling down and forehead resting against the soft bed as she takes everything that Levi gives her.

She comes first, grabbing a pillow to catch a moan that's bordering a scream. Levi revels in the feeling of her tightening around him and after Petra says yes, I can take birth control come inside me, captain please, he didn't even think. He just lets himself go and Petra moans further as he releases hotly inside her.

Petra slacks down on the bed with him following, his bare and sweaty chest against her back. He rolls away after he'd caught his breath, and Petra giggles from contentment and ecstasy.

Her giggles shoot straight down to his cock and Levi finds himself starting to harden again. She squeaks a bit when she feels his growing erection against her ass before smirking, a challenging glint on her amber eyes as she finally turns to face him.

No words were needed to be spoken and she tempts him by throwing a toned leg over his middle, inching her skin closer to his crotch.

Needless to say, Petra found herself on her back, knees almost touching her shoulders as the captain made sure she kept her legs open for each of his thrusts.

After that round, Levi could only exhaustedly lie on his back afterwards. His mind is still swimming after orgasming for the third time in a row.

He was about to ask her if she'd like to take a shower first before they sleep, only for Petra to roll herself on top of him. She started peppering kisses along his jaw and neck, making it a point to grind her exposed nipples against the hard lines of his chest.

"Fuck, again?"

"Didn't Hange tell you that the cart titan has amazing endurance?" Petra leans in, a coy smile on her lips. "I can go on for hours, captain."
