Diana smiled as Akko hugged her from behind and nuzzled into the fluffy material of her robe. Akko threw her leg over Diana's waist closing all space between them, making her girlfriend laugh.

"Are you a backpack now?" Diana chuckled.

"No, I'm a koala!" Akko replied, voice muffled by the soft fabric.

"Of course you are," Diana smiled. After today's events, she didn't want to part from Akko. As it turned out, the feeling was mutual and Akko decided to sleep over in Diana's private room. They were soulmates, it seemed wrong to just part ways and return to their dorms. Now the two were cuddled up together, unable to fall asleep. Akko felt a wave of adoration wash over her. She released her partner so Diana could turn around and properly face her.

Wordlessly, she kissed Akko, who happily returned Diana's affections. Akko gently held Diana's bottom lip between her teeth, knowing she loved it even if Diana would never admit it. This was a signal for Diana to part her lips further so Akko could deepen the kiss. When they parted for air, Akko trailed kisses along her jawline and throat while Diana tangled one of her hands in Akko's hair pulling her close. Her other hand gripped the fabric of Akko's shirt as if it was the only thing keeping her anchored.

This greedy side of her, the side that wanted to be spoiled, the side that allowed her desire to take over her pride, all of it belonged to Akko. Akko felt the intensity in her girlfriend and responded with her own wanting. She left a small bite on Diana's collarbone, noticing the way Diana's breath hitched and the pleasure that followed. That's new, Akko thought while taking a mental note to use more teeth in the future. Diana wasn't such a delicate princess after all.

Getting so lost in her lover, Diana didn't register Akko slipping off her robe until the cool air sent a chill through her. "A—Akko," Diana stammered feeling warm hands smoothing over her exposed skin until it reached the clasp on her bra. Feeling the sudden anxiety, Akko trailed her fingers along Diana's sides instead of removing the offending article. Diana felt a bit of disappointment coming from Akko but most notably there was understanding and concern. The fact she stopped as soon as Diana hesitated made her smile. She pushed Akko's bangs back and kissed her forehead.

"Diana we don't—" Akko started.

"No," Diana interjected, "I want to." She let out a sigh and embraced her girlfriend. "It's just—I've never felt this way before. I'm unfamiliar with all this and…I'm unfamiliar with my own body as well."

"What do you—" Akko felt Diana's embarrassment and the realization hit her, "Oh."

"You'll be the first person ever," Diana responded. "It never appealed to me, but now that I have you and I know what love feels like, I want everything that comes with it. I even researched—"

"Researched?" Akko asked incredulously. She imagined Diana diligently reading a smutty novel or analyzing an anatomy book. The traditional witch never cared for tech, so her 'research' would be very different from Akko's. She hoped Diana wouldn't ask her—

"What about you? Have you ever…" Diana trailed off unable to finish her phrase.

Damn it. "Not since I came to Luna Nova," Akko answered honestly hoping Diana wouldn't pry. While Diana sensed Akko's discomfort, she was too curious to leave it be. She'd never experienced the sensation herself.

"I heard it's common to think of someone you like when doing it. Did you have someone like that?" Diana inquired.

"Uh...yeah…I did" Akko stuttered. Because of their bond, she couldn't lie even if she wanted to. Nothing could have prepared her for this. She'd rather take on the Missile again that talk about masturbation with her girlfriend.

Diana's eyes widened, "Did you love her?"

"No! I just…admired her." Akko replied. Why? Just why?

Diana pulled back and looked into Akko's eyes, her piercing gaze seeing right into Akko's mind.

"Someone you admired…it's not Shiny Chariot, right?" Diana asked. Akko's embarrassment and guilt said it all.

"Really, Akko?" Diana sighed exasperatedly. She released Akko and buried her face in her pillow, laying on her stomach. She wasn't mad in fact, she should have seen this coming. However, Ursula had become a motherly figure for them both making this entire situation way too bizarre. She needed a moment to sort this out.

While Akko didn't feel any anger coming from Diana, she asked anyway, "Princess, are you mad?" No response came from the conflicted witch. Akko eyed Diana's exposed porcelain skin, she never put her robe back on. Akko crawled over to her girlfriend and placed a kiss on the small of her back, feeling her shudder. "Don't be mad! I only have eyes for you, Diana, I promise," Akko cooed while she nuzzled Diana's bare skin sweetly. She trailed light kisses wherever she could, occasionally suckling to create kiss marks. Akko knew Diana wasn't upset because of their bond, she was just playing hard to get.

Diana was enjoying Akko's attention and didn't even flinch when her lover unhooked her bra. Akko's possessiveness was stirring her up even more. Akko cherished every inch of her soulmate with her lips. Diana's heart fluttered at the amount of love and admiration that enveloped her.

Akko ran a single finger down Diana's spine, feeling lust ignite. She added a gentle bite to her kiss mark mission, experimenting with different pressures until she figured out Diana liked things a bit rougher than she originally thought. Akko was taking advantage of her soulmate bond with Diana, keeping track of every spike of pleasure she caused her lover. Slowly, she was mapping out her Diana's vulnerabilities so she could exploit them later. She moved away from Diana's frame only to admire her work. She watched as the bites and kiss marks created constellations across her beauty's back. Satisfied, she moved to Diana's legs kissing up from her ankle all the way up to her thigh. She wanted to touch Diana for so long and now that she knew Diana liked it, there was no stopping her.

Diana felt like she was being worshipped and subdued at the same time. Akko was spoiling her so much yet at the same time she could feel the intense passion coming from her companion. It was loving yet dangerous. Akko was physically stronger than Diana and she could do whatever she wanted. The athlete's energy made her think of a raging thunderstorm trapped inside a shell of lean muscle and smooth skin. While Akko could easily overwhelm Diana, instead she loved her with caution and caring caresses. Akko's elation at just being so close to Diana reminded her of her two dogs back home, making her smile into her pillow. Every motion was sincere and came from Akko's heartfelt desire to be closer to Diana.

Feeling bold, Akko grazed her teeth along her inner thigh before leaving yet another love bite. Akko loved Diana's voice, but the sweet sound was muffled as Diana bit back her moans. Diana was never the noisy type, so Akko decided to humble her girlfriend by tearing her voice out of her.

Diana felt the change but had no idea what her Kiwi was up to. Puppy Akko was gone for a moment, and a jolt of hunger emitted from her petite form. Without warning, Akko gripped the waistband of Diana's panties in her teeth and yanked them down.

THUMP

Akko took a pillow to the head for that, but she laughed and admired the red hue blooming on Diana's face. She wasn't angry, just surprised. However, Diana didn't pull her underwear back up. Instead, she completely pulled off the remaining article and sat straight up. She gave Akko's shirt a gentle tug. "You too," she ordered. Akko nodded her head and swallowed once before stripping off her top and shorts. Since she usually didn't sleep with a bra, she slowly pulled off the remaining piece of clothing, leaving her just as bare as Diana. At first, they sensed each other's insecurities erupt but soon all that came over them was awe and adoration.

Diana was too beautiful, Akko briefly wondered if she was real. Her long wavy hair fell over her creamy shoulders and her blue eyes twinkled in the dim room. Diana didn't bother covering her chest, allowing Akko to marvel at her supple flesh. This was her Diana, her soulmate, her friend, her princess, and her world. She wanted to reach out and hold her but, Diana looked so divine at moment Akko was too captivated to move. The only imperfections on her body were the love bites and hickeys Akko gave her, but they only served to arouse her more. Even the little scar on her lower lip seemed to have a charm to it. Akko let her eyes travel the entirety of Diana's body wanting to commit her frame to memory.

Diana always saw Akko as her adorable goof, her cute Kiwi. She loved Akko's bright eyes and soft round cheeks. Her pink lips were parted slightly, as she stared at Diana in awe. Diana could feel Akko's wonder and pondered if she could feel hers as well. Akko's form was full of contradictions, feminine yet strong, lean but with gentle curves. Diana would have never used the word sensual to describe the witch before, but now it seemed like the only word that fitted. She needed to touch her. Diana embraced Akko slowly, relishing the girl's warmth. She could feel Akko's heartbeat against her own.

Akko pulled away a bit in order to kiss Diana again. She pulled Diana into her lap and firmly held her in place by her waist. Diana wrapped her arms around her lover's neck as she felt Akko deepen the kiss. She then trailed them down Akko's front until she reached her chest, cupping the soft flesh gently. Akko gasped into the kiss and broke it so she could nuzzle Diana's shoulder. Diana continued to massage Akko's chest while nibbling at Akko's sensitive ear, making sounds of pleasure escape her lips. Akko laid down on the bed and dragged her hand from Diana's thighs to her rear before giving a firm squeeze. She smirked into Diana's shoulder when earned a squeak of surprise. Diana bit Akko in retaliation making her chuckle.

Diana kissed down Akko's toned stomach and her inner thigh. She gazed into Akko's eyes for approval before tentatively touching her most sensitive region. Akko let out a little moan when Diana traced her front with her fingers. She admired Akko's shy yet eager expression. Her face was flushed and she bit her lower lip in anticipation. "Diana…" Akko whimpered. Diana smiled at Akko before giving her another kiss, hand never leaving her core. She gently pushed past Akko's entrance making her gasp again. She was going to ask if Akko was in any pain but she could feel a tidal wave of pleasure emit from her lover. Instead, she carefully pushed forward, looking for Akko's sweet spot.

She wasn't lying about her research. Akko let out a much louder moan once Diana found it and proceeded to massage that point, alternating between massaging the rest of the area and Akko' sweet spot so as not to overstimulate and hurt her love. Diana moved her head back to Akko's chest, kissing one of her sensitive peaks before wrapping her lips around it. Akko's hand moved to Diana's head, tangling in her hair, the other one fisting the sheets. Diana could feel Akko building up. Out of nowhere she said something in Japanese and Diana was somewhat upset she had no idea what, but it was incredibly sexy. She made a mental note to work on her Japanese over the break. Akko's uneven breathing quickened. "Diana, I— "Akko started.

"It's ok, love. Go ahead," Diana said, feeling Akko tighten up around her fingers. She could even feel Akko's oncoming climax through their bond, making the moment surreal. Akko cried out and held Diana's wrist to stop her from moving. Diana only removed herself when she felt Akko recovering from her orgasm.

"Are you sure you've never done this before? You're not allowed to be amazing at everything!" Akko remarked between breaths. Diana just chuckled and laid down beside her.

Diana delighted in the rise and fall of her chest, her flushed cheeks, her warm smile, and her loving eyes. She'd seen a new side of Akko and she hoped to see more in the future. Diana leaned in for another kiss, this one gentle and slow compared to the heated ones they shared moments ago. "Diana, I want to touch you too," Akko whined while snuggling into the crook of Diana's neck.

"After you recover your strength, you can" Diana responded. She subtly rubbed her thighs together, hoping Akko wouldn't notice her lust rising. She was already bothered from Akko's teasing earlier, but now she felt like she was on fire after seeing Akko come undone. However, her efforts to hide her were in vain. The moment Akko's head cleared she felt Diana's raw need. She flipped her girlfriend on her back easily and started her assault from Diana's neck. She mimicked her earlier actions, leaving love bites in soft flesh. Diana was caught off guard and mewled as Akko massaged one of her breasts while suckling on the other. Akko dragged her teeth across the sensitive peak, forcing a moan out of Diana. She continued to leave open-mouthed kisses along Diana's torso as she moved lower. She made sure to nip at Diana's inner thigh and bit hard enough to leave a mark, but not enough to break the skin. She'd been waiting for this for so long, and apparently so did Diana.

Diana couldn't comprehend how Akko seemed to know her body so well. While Diana had a general idea of sensitive locations thanks to her research, Akko knew of oddly specific areas that Diana would have never thought to pay attention to. She seemed to understand more about her body than Diana did herself, manipulating her until she writhed. Diana whimpered when she felt Akko's teeth, it was a strange mix of pain and pleasure. "You're a bit of a masochist, huh Diana?" Akko smirked against her inner thigh. Diana shuddered, she could feel Akko's warm breath against her center and it was driving her mad!

"I'm not—" she was cut-off by a wave of euphoria as Akko bit her again. Akko didn't tease her again though and gently ran her tongue over the bite in a soothing manner. "Akko, please."

"Please what?" Akko grinned. She sat up straight and pulled Diana closer to her by her waist. She then leaned over and intertwined her fingers with Diana's. Diana's breath hitched when Akko rolled her hips against her. She needed friction, but Akko was being a bully! The person on top of her wasn't her sweet Kiwi or the breathless girl she pleased. This Akko was going to eat her alive. Diana wrapped her legs around Akko's waist, pulling her impossibly close. It still wasn't enough.

"Akko, you know what! Just do it!" Diana whined.

Akko moved Diana's hands above her head, pinning them there effortlessly. She used her free hand to gently stroke Diana's center. She smirked when she felt how ready Diana was, but she didn't oblige. Instead, she continued to tease her lover, making Diana feel new heights of frustration. "Akko, I need you. Please, don't bully me," Diana begged.

Akko loved Diana, there was no question about that, but for some reason seeing the usually authoritative witch so submissive and frustrated made something click for her. She decided to finally give her soulmate release. Akko removed her hand completely, making Diana groan in frustration. She then lowered herself to Diana's center.

"Akko, Wait! That's—" Diana threw her head back and mewled as she gripped Akko's long hair and pulled her closer. Akko didn't want to accidentally hurt her since Diana never touched herself before. This was the best option. Akko held Diana in place by her thighs to keep the girl from bucking. Diana forgot about one particularly sensitive area, but Akko decided it would be a good time to teach her. She flicked her tongue against the small bundle of nerves.

"AKKO!" Diana screamed. The pleasure was so intense it was almost painful. As Akko built Diana up towards her climax, she carefully slipped a single finger inside. Diana tightened up around Akko as she gently explored uncharted territory. Diana had found a certain spot earlier that drove her crazy! She wanted to return the favor, but where—

"Shit!" Diana gasped.

Guess I found it, Akko thought to herself. Her second finger slipped in easily without hurting Diana, much to her relief.

Diana felt her release coming. Akko's soft tongue and knowing fingertips were too much! "Akko, I—"

Diana screamed Akko's name, her voice filling the room. Akko waited until Diana relaxed before extracting herself. She felt satisfied with her work and looked up at Diana.

"Don't you dare even think about kissing me," Diana warned. Akko pouted, but it was understandable. She retrieved a towel from one of Diana's drawers and proceeded to clean up. Diana was still out of it, drawing concern from Akko.

"Diana, are you ok? Do you want some water?" Akko asked, walking over and massaging Diana's shoulder.

"I'm fine, just give me a moment," Diana assured while trying to catch her breath. She just had her first orgasm at the hands of her darling. Diana looked absolutely defeated, face flushed and eyes dazed. Maybe it was because they were rivals, but a defeated Diana is something she needed to see more of. Feeling the sudden lust emit from her partner she sent a glare at Akko.

"I can't help it! Diana, I love you. Let me show you how much you mean to me," Akko said as she pulled Diana's back against her chest. She seemingly reverted into her Kiwi, though Diana knew better.

"No," Diana stated simply. It was hard to resist Akko when she asked so endearingly, holding her close against her chest. However, she remembered that not only was Akko athletic, she was trained by Ursula of all people. Akko's stamina was way above the average individual's.

She would love Diana to death if she let her.

Diana felt her girlfriend trace circles into her shoulders, making her feel drowsy. She would have drifted off if Akko didn't attempt to subtly move her hand closer to Diana's chest. "Akko, down!" she chided. Akko groped her rear instead. I'm dating a succubus, Diana thought.

"Can we at least take a shower together? I'll behave!" Akko whined.

"You most certainly won't," Diana responded dryly, yet she got up anyway. "Let's go, these intimate sessions are nice, but the aftermath isn't."

"Intimate sessions?" Akko chuckled as she got up. "But you're right, this is sort of gross. It'd be nice if you had your own bathroom—"

"I do," Diana responded as she opened what Akko thought was a second closet for research materials.

"You never told me you had a personal bathroom! You're a true aristocrat, Princess. I'm so jealous," Akko exclaimed as she entered the bathroom. Under the bright light, she could see all the markings she left on Diana.

"I didn't realize you left so many," Diana remarked as she caught her reflection in the mirror. "I suppose I'll need to heal these." For some reason, the idea of Diana erasing her marks disappointed her. Diana sensed the change and smiled, "I guess you'll need to do it again. Later."

Akko beamed at her and followed Diana into the moment the water turned on, Akko slid her hands up Diana's sides. "Do you want to sleep on the floor?" Diana threatened. While the motion was innocent, Diana didn't trust herself either. Akko was too sweet and too…talented. She'd easily fall back under her soulmate's spell and lose herself. Akko laughed but kept her hands to herself after that.

When they re-entered the room, Diana pulled her robe over her bare figure, not bothering with undergarments. As they snuggled up next to each other, Diana felt fondness coming from her companion. Akko stroked her girlfriend's hair gently, every movement filled with love.

"Akko?" she called sleepily.

"What is it?" Akko asked, still petting , Diana was the one who coddled her but behind closed doors, Akko returned the favor.

"Next time, I'll get you back," Diana challenged before drifting off.

Next time.

How was Akko supposed to sleep after that?

The morning after

Akko had woken up before her and left Diana to sleep in while she started their shared duties alone. Diana smiled at the cute note her girlfriend left for her as well as a pitcher of water with heart shaped ice cubes. Diana poured herself a glass and sipped it while she entered her bathroom. She noticed a small mark on her neck. When she opened her robe, she noticed that her chest, thighs and upper back were once again covered in kiss marks. I thought I healed these, how—

She noticed a new bite mark on her butt. The realization hit her.

I'm seriously dating a succubus.

Bonus

"Akko, why are you molesting your pillow?" Hannah asked as she entered the red team's dorm. Barbara asked her to return some books to Lotte, but when she arrived she was greeted with the sight of Akko unbuttoning a blouse she put on a pillow.

"Actually, she's molesting my pillow," Sucy corrected. "She got her hands on some crappy magazine about 'impressing your lover' or something. It's considered sexy if you undress someone completely without fumbling."

"Is that Diana's blouse?" Hannah inquired with her arms crossed.

"I need it! It's a necessary sacrifice for our relationship!" Akko defended.

"Akko's been practicing for the past three days," Lotte added.

Hannah rolled her eyes, "Where did you even get these?" she asked while picking up one of the magazines.

"Barbara lent them to me," Akko responded as she re-dressed Sucy's pillow for another attempt.

"Barb did?" Hanna asked in disbelief. If Barbara found these things attractive...

"I'm taking these," Hannah declared while confiscating the magazines.

"Please do, you'll be doing us all a favor," Sucy commented. "You weren't here when she read about serenades. It was awful." Lotte let out nervous laughter.

"You can't take those! I need them!" Akko argued.

"Too bad," Hannah replied while dashing out of the room. Akko was cute and Diana was already head over heels for her. I need them more!

"Hannah! Are you standing in the way of my love!? Get back here!" Akko said while chasing Hannah.

Sucy and Lotte looked at each other and shrugged.

Just another day at Luna Nova.

Author's Notes:

In real life, concrete consent is extremely important! One should always gain permission from their partner before proceeding. You should actually ask if hickeys are ok too because the marks will linger since they are technically bruises, becoming a nuisance.

I in no way shape or form think it's ok to leave any marks without proper consent.

I wrote this to mostly capture their character. Akko and Diana are still learning the ropes and don't know how to properly do these things yet. I think in Akko's head, it's a harmless prank, not realizing what she did was wrong. They're doing stuff based on their "research", after all. It's not what I personally think, rather how I think the characters would act, based on Akko's impulsiveness and impish nature. She's a good bean! She just needs some guidance. I feel like Diana wouldn't be mad since she understands Akko doesn't mean any harm, but she recognizes that something isn't right.
