As soon as they had a chance, Komaru tackled her brother into a shrub and started to kiss him. It had been only a few minutes since classes had ended at Hope's Peak, but she'd been wanting to see him all day.
Makoto pulled her away and grinned. "Miss me~?"
"Don't speak, only kiss." Komaru said before she wrapped her arms around his neck and kissed him passionately.
Makoto moaned into her mouth while reaching down to grip her ass through her skirt, delighting in how she ground against his cock while adjusting her body on top of him.
She giggled against his lips as she started forcing her tongue inside his mouth, reaching behind him and nearly clawing at his back as she grinded her body against his own.
"Hehe, oh my~" chuckled a voice that was only tangentially familiar to Makoto from the outside of the shrub.
Komaru froze in place as she glanced over to find a buxom girl with glasses staring at them.
"Tsumugi!?" Makoto panicked, trying to push Komaru off of him as if that would somehow make everything okay.
"Oh I recognize you~" Tsumugi purred to his sister. "You're Makoto's sister!"
"Uh, uh! Panic! Um, Makoto!"
"No she's uh-" Makoto tried to reply. "My cousin!"
Komaru smacked him. "Uh…I'm not his sister or his cousin, I'm…a secret lover! You can't tell anyone, okay?"
"Nice try," Tsumugi winked. "But not even Light Yagami could conceal such an obvious truth. You two look so similar, and that little ID badge on Komaru's chest says 'Komaru Naegi.'"
Makoto looked down at the 'Hope's Peak Visitor Badge' dangling from his sister's chest. "Shoot..."
"Please don't tell! We'll do anything!" Komaru cried.
"Of course I'm not gonna tell, why would I?"
Makoto and Komaru both froze, only for the blue-haired cosplayer to giggle again.
"Sometimes you go to the video rental store hoping to find Darling in the Franxx, and you find Evangelion at a discount instead, y'know?"
"Uhh…what?" Makoto asked.
"Great, she's a nerd, too." Komaru paused as she looked the girl up and down. "She's definitely hot, though."
"The point is," Tsumugi continued. "Obviously you two have few to no sexual limits if you're just going to be having sweet, sweet sisterly love in the middle of a bush on school grounds, so you're more than happy to help me with a little 'problem,' right~?"
"Problem?" Komaru asked, growing simultaneously more excited and nervous.
"Have you ever raped someone?"
Later that night, Tsumugi was taking her 'usual' nightly stroll down a dark alley in the middle of town. The area was dark and forboding, the only nearby source of light a street lamp that she had left behind. It was a place any other girl would've been scared to walk at that time. Suddenly, she heard a rustling near one of the buildings that made her freeze. "Uh…who's there? You'd better show yourself!"
Before she could react, someone grabbed her and pointed what felt like a knife to her back as they leaned in to speak into her ear. "Hey there, you pretty little thing~! Why don't you come with me back to my house so we can spend some quality time together~?" The person said in an, admittedly, bad gruff voice.
Despite that, Tsumugi was almost immediately soaking wet. Still, she had a part to play. "W-w-why!? I'll give you money-"
"I don't want your money." The person said as Tsumugi suddenly felt a land latch onto her backside. "I want…you~"
She had to bite her hand to keep from moaning. "P-p-please…I'm a virgin-"
The person smiled. "Perfect. Now…move." They said, sticking the object harder against her back.
Tsumugi began walking, her steps short and nervous as they reached the end of the alley.
The figure led her all the way to a house with its lights off, groping her ass the entire time. Once they were inside, the figure led her up the stairs and into a bedroom, before they pushed Tsumugi onto a bed, and the door closed behind them, revealing another person who had been hiding behind the door.
Both Makoto and Komaru were dressed in plain shirts and jeans with sunglasses to 'conceal' their identities, and despite how mundane it looked it worked for what Tsumugi wanted. Makoto spoke up. "If you tell anyone what happens here…we-we-we'll kill you-"
Tsumugi gripped the bedsheets, the groping combined with the knowledge of what was about to happen nearly making her collapse in lewd bliss before it even happened. "Please don't…I…I don't even like men!"
Komaru stepped forwards and grabbed the girl's shirt, ripping it open and popping several buttons off as the her lacy blue bra was revealed to the two.
Meanwhile, Makoto grabbed her skirt and yanked it down her legs while she 'fought' back enough to seem like she struggled without actually disrupting them.
"No, stop!" she protested. "I have money!"
"Shut up, bitch." Komaru said in her bad gruff voice as she went the extra mile to strip her off her socks and shoes before grabbing her bra and tearing it off her body, the girl's large chest bouncing wildly.
Tsumugi couldn't resist moaning even as she playedher part. "D-don't call me that!"
Makoto smacked the girl's cunt through her panties before, in an equally horrible gruff voice, replying "We'll call you whatever we want."
"I cannot wait to hear you scream for us~" Komaru said as she grabbed Tsumugi's panties and tugged them off, tossing them aside and leaving the girl completely nude before them.
The girl tried to cover her pussy as she squirmed away from them. "W-w-what are you going to do?"
"I'm not sure, what should we start with~?" Makoto asked his sister.
Without a word, Komaru jumped the girl, straddling her stomach as she grabbed onto both breasts and squeezed hard.
Makoto watched as Tsumugi yelped and kicked out, unable to get Komaru off of her. "Stop, those are sensitive!" she whined.
"That's the point, now stop whining!" Komaru said as she pinched one of the nipples and twisted it, tugging it upwards as her other hand sank further into her breast.
All pretense of resistance ended as Tsumugi let out a harsh squeal of pleasure, her drenched pussy obvious to Makoto as her legs twitched.
"Come on, you can take care down there while I play with these." Komaru said to her brother as she gestured to the girl's wet pussy. Makoto nodded, stepping forward before reaching down to harshly pinch on the girl's clit.
"AH!" Tsumugi screamed as pain jolted through her body, forcing her to a level of arousal she had never truly felt in her life.
"Such a little whore, getting so turned on by a couple of strangers having fun with you like this~" Komaru said as she pinched both nipples and tugged on them, hard, stretching out her breasts.
"I'm not-" she weakly protested as her pussy was suddenly filled by two of Makoto's fingers.
"Don't be a liar~" Komaru said as she started to shift her lower body, grinding herself against Tsumugi. "You just want him to stick his big, thick cock in you, don't you~?"
Tsumugi practically drooled as she remembered her set-up. "No, I don't! I don't like men, I have a girlfriend!"
Makoto reached for his zipper with his other hand while pumping his fingers in and out of her pussy. "I doubt she'd want you once we're done, who would want a broken little girl like you~?"
"Especially one who would get off to something like this." Komaru said as she grabbed her shirt and removed it immediately, revealing a complete lack of a bra as her breasts bounced. The Ultimate Cosplayer felt herself drooling as she stared at Komaru's chest. Maybe when they were done here she could suck on them.
Makoto interrupted that thought by pressing the head of his cock against the lips of her pussy. "Anything to say before we take your virginity~?"
"She doesn't need to say anything at all~" Komaru said as she leaned down and buried the girl's face in her breasts.
Huh, Christmas came early, Tsumugi remarked to herself as she began frantically kissing and licking at Komaru's breasts while Makoto inserted himself into her. Komaru moaned loudly as the cosplayer kissed them, and her body continued rocking against Tsumugi's. Her panties were slowly becoming soaked as well.
Makoto leaned forward and rested his body against Komaru's back, letting only his hips move as he forced himself in and out of Tsumugi's tight pussy. Komaru moved backwards, so that her breasts were no longer in Tsumugi's face. Instead, their chests squished together and Komaru kissed the girl.
Tsumugi broke character to reach up grab the back of Komaru's head, forcing her to hold still for the kiss while she pushed her tongue into the girl's mouth, while also trying her best to wrap her legs around Makoto's back to keep his cock buried inside of her.
Komaru happily let her, and their tongues wrestled as Komaru began to finger herself, though it was a bit of a struggle to do so.
Makoto pulled out to avoid cumming too early, instead reaching down to rub Tsumugi to a harsh orgasm. Her moans into Komaru's mouth and the jolting of her body against Komaru's stimulated both girls much more.
Komaru could already feel herself coming close so she kept moving, faster and faster, grinding harder against Tsumugi as her did her best to thrust a finger and out of herself, until finally, she came, moaning into their combined lips as she stained her panties with her juices.
Tsumugi melted against the bed as Makoto took a step back and Komaru climbed off of her.
"Don't get comfy yet, we're not done with you." Komaru said as she grabbed Tsumugi and started moving her around. She positioned the girl to where her head was now lying over the side of the bed, upside down as Komaru crawled onto the other side, and spread the girl's legs wide, allowing her to see just how wet she was.
Makoto reached down and took a gentle grip on her neck, forcing the blue-haired girl to open her mouth slightly to breathe better right as he placed the head of his cock against her lips.
At the same time, Komaru stripped down the rest of the way, for her own enjoyment, and knelt down, spreading her legs further as she leaned in, and gave the girl's pussy a single lick.
Tsumugi's legs immediately clamped around Komaru's head, forcing the girl's face against her lower lips as Makoto thrust forward into her throat, causing her to loudly gag as his grip grew tighter.
Komaru was stunned for only a moment before she grabbed the girl's hips and started lapping at her bountiful spring.
Makoto strangled the girl as he violated her throat, pounding in and out of her as his balls smacked against her face, every thrust further degrading her as her entire body was dominated by the feeling of pain from her upper half and pleasure from her lower half.
Komaru's tongue wiggled inside, tasting as much of the girl as she possibly could, feeling her body vibrate in pure pleasure as the sweet juices coated her tongue.
The last straw for Tsumugi was when Makoto released her throat just to quickly smack her in the chest. The last, extra bit of stinging drove her over the edge again, causing her to squirt into Komaru's mouth and over her face.
Komaru happily lapped it all up, before, once Tsumugi released her, she swallowed whatever was in her mouth and on her tongue, and wiped her mouth, sighing in satisfaction.
Makoto came next, hilting himself in Tsumugi's mouth and cumming deep enough into her throat that she was forced to try and swallow every drop, only coughing up a bit when he pulled out and left her laying on the bed, more thoroughly exhausted than she had ever been.
All she could do was let out a little moan of relief. "I-I think that's enough..."
Komaru sighed. "That was…interesting."
Makoto sat down on the bed next to Tsumugi, putting his dick away and pulling his pants back up. "Did we do alright?"
The blue-haired girl rolled over and exhaled. "It was amazing, thank you~"
"I'd be down to do it again sometime!" Komaru said with a wide smile. "Because you are…very hot. And I want to do…a lot more things to you sometime."
Tsumugi looked back to the girl while 'inadvertently' spreading her legs, giving Komaru another look at her pussy while she winked. "I'd love to if your brother is up to it~"
Makoto rubbed the back of his head and giggled. "S-sure, it'd be fun."
"For now…um…you should probably leave before our parents get home." Komaru said as she pointedly stared at the girl's crotch.
Before Makoto could concur, the trio heard the front door open, and a voice call from down the hall. "Kids, we're home!"
