Tsumugi is an underrated gem who needs to be loved more. 

Also, I somehow made this into a yandere fic because it seemed to work so well with the plot of DRV3.

WARNING: This chapter takes place during the killing game, so there will be major V3 spoilers. I'm talking HUGE SPOILERS. So read at your own risk. 

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

"Y/N, everyone will see..."

"Isn't that the point of a hickey...?" 

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

'Y/N L/N, the Ultimate T/N. She was chosen to become this season's traitor after winning the audition for Danganronpa's 53rd killing game. Her audition went smoothly, and she was soon tasked to join forces with Tsumugi Shirogane, the mastermind behind it all.'

'The two were inseparable. Working together like partners in crime. In fact, it wasn't long until the two of them started developing feelings for each other. Becoming the Ultimate Power Couple if it were even possible.'

'It was almost like it was meant to be.... so why...'

'Why was she still hanging out with her...?'

You grit your teeth and cut your monologuing short. Watching as Tsumugi and Kaede bonded over their free time event. 

'Stupid protagonist... you could've chosen anyone else, but you had to pick my beloved.'

You were easily the jealous type. Watching in envy as the two seemed to be having a good time. Laughing and bonding over dorky stuff like 'We're so different but that's okay because we bond anyway due to the fact that you're the protagonist.'

You hated Kaede. With how the game was running, Kaede was easily living up to her role as the protagonist. Catching the hearts of pretty much everyone --including your beloved-- like some harem protagonist. (You learned that term from Tsumugi) 

So when you later spotted Kaede and Shuichi discussing their plan to catch the mastermind, you couldn't help but devise a plan to get rid of her. Knowing the perfect opportunity to rid of your rival, and make the killing game more interesting. 

'I can't do anything to you, Kaede. But Monokuma can. I'll take what I can get...'

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

Washing the blood off your hands, you sighed and quickly changed into a new set of clothes. Though, they looked exactly like your old ones due to the cliché rule of 'characters only have one outfit.'

Sighing, you stared at yourself in the mirror, a look of pure satisfaction on your face. 'Won't be long until someone comes across the body,' you smirked, feeling victorious at your deed. 'Tsumugi will be proud of me.'

Stepping out of the bathroom, you paused to see Tsumugi sitting on your bed. One leg over the other and twirling the spare key to your dorm in her hand. 

"I see you broke in," you mumbled.

She giggled and smirked back, tossing the spare key behind her. "It's a better crime than what you did. I saw everything back there..."

You hummed nonchalantly, "What crime?"

Tsumugi grinned and stood up to meet with you eye to eye. "You know what you did. I admit, I never took for you to be such a yandere, Y/N. It's kinda hot if I do say so myself..."

You rolled your eyes and giggled, "You and your weebish tendencies..." 

Pushing her back with your finger, your smile faltered when your memories of their free time event resurfaced. "Why did you have to hang out with her...?"

Your girlfriend smiled at your obvious jealousy and giggled. "You know exactly why. I can't decline a free time event, Y/N. I'm still a character after all."

Playfully pouting, you pushed Tsumugi towards your bed, making her gasp and fall back. "But I was jealous Tsu-Chan... you did it right in front of me..." you huffed and straddled her lap, making her face burn pinker than blood itself. "You made me jealous."

Blushing, Tsumugi gasped when you pinned her hands to the sheets. "Such a shame... Rantaro-Kun had to pay for your mess. And knowing you...you wouldn't want your favorite character to die, would you...?" you whispered sensually into her ear, your hot breath tickling the outer skin. 

She shivered when she felt your lips nip at her skin. "Would you...?"

She shook her head, knowing exactly what you wanted her to do. "I'll...I'll frame Kaede..." she whispered, kissing your jaw. 

"Good girl..." you whispered, leaning back and examining her features. 

While she was in control of the killing game, you were in control of the bedroom. And it definitely showed with how jealous and possessive you were, enjoying every pant of air that drained from her throat. 

Her hair was fanned out across your bed, a look of pleading lust etched in her eyes. She wanted more, you could tell. 

"Y/N..." she whined, "Kiss me?"

You held in a giggle, brushing your hair back and leaning down. A smirk evident on your features. "I dunno, do you really deserve one?" Your voice had a mocking tone in it before she reached up and gripped your neck, pulling you down for a full blown make out session. 

Her lips sucked against your own, wanting and desiring for more to happen with you. Something more...exciting. It was clear on what she wanted, and whenever you guys did it, it was always a fun surprise for you two to enjoy. After all, you were chosen as the traitor for a reason. 

You were so unpredictable...

Tsumugi parted her lips for you to enter, and the two of you French-kissed passionately, your tongues tangling with each other like a tied cherry stem. 

'She's heating up so much...' you smirked during the kiss and pulled back, breaking it and leaving Tsumugi breathless. "Y/N...wha...huh...?"

"I'll leave it at that. I don't think you deserve my love right now," you pouted childishly before grinning. "Sorry not sorry, love!"

She narrowed her eyes at you and frowned. "Y/N...please~? Pretty please with a hope bagel on top?"

You snorted at the reference she made, giggling at the old joke that existed years ago. Back when the second killing game was first streamed. "You and your indirect references..." you shook your head and planted a loving kiss on her forehead. "If you want something, you need beg for it."

Tsumugi 'tsked' and looked to the side, exposing her bare neck to you. "Please, Y/N? Please...?"

"Mm, please what?" you tilted your head innocently, leaning back down to her neck. "Do you want me to...do this...?" you hushed your voice to a whisper and licked the narrow of her neck, causing her to squirm and writhe in surprise. 

"Y/N!" she gasped, "There, please."

You continued to caress the nape of her neck with your tongue, slowly leaning in to suck and bite at the skin. Pinching it with your teeth, you successfully left a light purple bruise in place of her skin, making her whine with annoyance. 

"Y/N, everyone will see..."

"Isn't that the point of a hickey...?" you answered nonchalantly, continuing to suck and mark against her neck. 

She continued whining and writhing in desperation. "Y/N come on, this isn't fair. Let me touch you too...!"

You shook your head and leaned down to take the ribbon of her uniform into your mouth. "No, thfis is fyour punismfwent," your words were a bit muffled due to the fact that you were literally untying Tsumugi's ribbon with your teeth. Making her squeal with giddiness. 

'Ahhh she's so hot...' she thought, literally exploding with adoration. 'Definitely best girl...'

Once you undid the ribbon to her uniform, you carefully popped each button of her shirt open. "Y/N, it's not fair if you don't get naked too," Tsumugi argued, a proud smile on her features. She was going to tease you for once, she was sure of it. 

Though, that only backfired when you answered with;

"Oh? Okay then," your blunt response made Tsumugi shiver with surprise. It only increased when you didn't even hesitant to unbutton your shirt and pull it off your body. 

'N-No hesitation-- THAT'S SO HOT DEHUSFHEVFIR--'

With your bra now exposed --and your expression still composed (hey that rhymed)-- Tsumugi became a flustered mess, her standard persona falling over her as she babbled about how hot you were. 

You only watched in amusement, waiting for something like a nosebleed to occur just in case she lost it. 'She's so cute...' you thought, smiling when she turned pink once more. 

"Tsumugi," you called out, interrupting her from her ramblings.

She blinked, looking up at you with a flustered gaze. You smiled cheekily at her and tilted your head, "Do you still wanna continue?"

Blushing even more --if possible-- she nodded, letting herself succumb to you. "Of course I do..." she shyly muttered, closing her eyes and moaning quietly when you sucked against her exposed collarbone. 

'A gentle yandere...how sweet...' she smiled slightly, letting out a soft moan when you latched another bruise into her skin. 'Well...maybe not so gentle...'

"Eager aren't we?" she joked, watching you tug her skirt down. "Says the girl begging for me to eat her out," you answered bluntly, not even looking up to meet her gaze. 

Smiling, you knew you didn't even have to look up. You already knew that your girlfriend was a blushing mess, probably covering her face with her hands. 

'Always a docile one...' you grinned teasingly and pulled her panties to the side, watching as her clit was literally dripping wet. Dripping wet for you...

"I did that...?" you exclaimed innocently, covering your mouth shyly to add to the dramatic effect. "Y-Y/N...!" Tsumugi whined, already embarrassed from your constant teasing. Giggling, you leaned down and felt heat radiating from her puffed lips. Throbbing and wanting for a sensitive touch...it was almost admirable. 

"Y/N..." she groaned, sounding more demanding the longer you waited. 

"Sorry sorry, but keep in mind Tsu-Chan," you peeked up at her with a mischievous glint in your eyes. "This would've gone by a lot faster if I weren't so jealous..."

She huffed tiredly, almost irritated at your words before gasping in pleasure. A spark of sensitivity running through her body like an electric current. 

'I-It's touching...'

Her eyes glazed over with lust as her brain comprehended the action. You were in fact licking her, the wet muscle glazing over her lips in a slow and almost pain-staking manner. The slicked arousal from her snatch mixing in with your saliva. 

"Y/N..." she whined, tugging at your hair gently, "More..."

You rolled your eyes at her pleads, continuing to eat out your girlfriend like you were starving. 'So needy...' you thought silently, gripping her thighs when she started twitching at your touch. 

"Y-Y/N-- Y/N I-I--!" her voice grew higher in pitch. Octave by octave, her moans slowly filled the room like a melodic instrument. Pitches of sounded pleasure leaving her lips in an attempt to satisfy you. 

'She must be close...' you concluded, feeling her inner walls clench tighter at your tongue. 

"Y-Y/N...Y/N--!"

You quickly leaned back from her clit, grinning when disappointment and annoyance littered her face. The pleasure leaving her eyes as a hot and bothered Tsumugi glared at you. 

"Y/N...what...what the hell?!"

Licking your lips and wiping the rest off, you stood up and grabbed your shirt. Slipping it on without a care and beginning to button it up. 

"I don't reward people who make me jealous," you sighed, smiling so innocently that it made Tsumugi want to hurl a brick at you. 

"Y/N you prick!" she whined, her legs trembling while juices dripped down onto your sheets. You'd have to get them changed later...

Chuckling, you bowed to give your girlfriend one last kiss before separating. "If you want to cum so badly, you know exactly what to do with Kaede after the trial."

In a frenzied daze to do anything for her release, Tsumugi nodded enthusiastically, reaching forward to hug and kiss your neck. 

The sounds of bells cut your moment short as Monokuma's irritating voice echoed over the loudspeakers. 

"A BODY HAS BEEN DISCOVERED!"

You grinned psychotically, knowing full well who the murderer was. "Poor Rantaro-Kun... Oh well! He was just another pawn for me to play..." you giggled childishly. 

Following pursuit, a despaired look rose to Tsumugi's face, giggling in your embrace. "Don't worry, Y/N. I have it all under control..."

The traitor and the mastermind, their love so strong...

They'd kill anyone for each other...
