"No staying up too late, no parties, just on wild stuff in general!" The Naegi's mother continued as their father practically dragged her out the door.
"They'll be fine dear, we've raised good kids. Right, kids?"
"Yeah!" Makoto cheered.
"You guys have fun!" Komaru said with a smile as she stood next to Makoto, waving off their parents. They hadn't managed to find a babysitter in time so their parents decided to try letting them stay by themselves this time, promising that this wasn't gonna be a regular thing just yet.
Makoto watched them finally leave before walking forward and locking the door. "So, we have the full week to ourselves..."
"I know of a few things we can do~!" Komaru said with a wide smile.
Makoto smiled a little. It had been two years since their 'relationship' had begun, and Komaru was as adorable as ever. She had mostly been under control this whole time, but she had grown quite a lot. After all, this was around the time of her life puberty would begin. "Oh, like what?"
Komaru threw her body against Makoto's now modest breasts squishing against Makoto's own chest as she placed her hand over his crotch. "We could have some funnnn~"
Makoto chuckled a little before pushing her away. "Sure, but not yet. I have homework to do."
Komaru pouted. "But homework is boriiiiing."
"It's not like I'm getting into Hope's Peak Academy when I'm older-" Makoto shrugged as he juked past her. "So I need to keep my grades up!" Komaru sighed, and started following him, feeling her chest bouncing as she walked, since she'd decided to not wear a bra for this specific purpose. "Unless you're gonna help me study pre-calc, you should find something else to do for an hour. The living room is wide open."
Komaru wrapped around him from behind and shoved her hand down his pants and boxers, running her fingers along his dick. "Come onnnnnn, pleeeease~?"
Makoto squealed and spun around. Usually Komaru wasn't this…forward- "No! After dinner." Ignoring him, she threw her body down, and yanked down his pants and boxers, his dick flopping out immediately. Makoto yelped and fell to the ground. "Komaru, I'm serious!"
"So am I! I wanna have sex!"
"And I don't!"
"Ughhhh, fine!" She yelled, and stormed off into the living room. Makoto pulled his pants on, but he couldn't help but follow her with his gaze. What had gotten into her?
Komaru angrily threw off her clothes as she walked to the couch, and sat down naked. She spread her legs, threw one hand between them, and the other over her breast. She then thought of Makoto as she very loudly began to masturbate. Makoto had managed to crack open his textbook before the sound of his sister's moaning pierced into the room. "Komaru!?" Komaru responded by moaning even louder as she frantically thrust her finger in and out of her pussy. Makoto felt his cock twitch through his pants as he tried to learn the basics of calculus. Why did she have to be so loud? Normally she was so good at being quiet.
Hoping she was having the right effect she wanted on him, she kept going, letting her voice leave her lips as loud as she could comfortably make it as she added a second finger, the shlicking loud and apparent as she went. The whole thing made Makoto wince a bit. She was going hard enough he could hear the sound of her fingers in her pussy from across the hall, and her moans sounded as if they were in the same room. Makoto sighed and set down his pencil before marching into the living room.
"Komaru, what's the big deal?"
As soon as he entered, she came, spraying her cum onto the couch and the floor, even though she knew she'd have to clean it up later. She made sure to look him in the eyes as she finished, before collapsing back onto the couch. Makoto was a bit shocked by the eye contact, but his annoyance at being behind on his scheduled studies reinforced his resolve. "Komaru, answer me."
"Y-you didn't want to…so I did it myself…" She answered as she stood up on wobbly legs and made her way to the kitchen to grab paper towels, making sure to sway her hips as she walked.
"You've never had that problem before," Makoto replied, thinking of how many times he had to teach her that 'those kinds of games' weren't appropriate to do in public, of all places. "What's the matter?"
"I'M HORNY, WHAT DO YOU THINK?!" Komaru cried as she grabbed the towels and made her way back to the living room.
"Komaru, calm down!" Makoto chased after her along the way. "This isn't like you y'know!" Knowing he was still behind her, she bent over as she began to clean the cum on the floor and couch, shaking her hips slightly. "Komaru, I know what you're doing," Makoto huffed. "If you don't talk to me about this, I won't touch you this entire week."
Komaru groaned as she stood up and turned around. "What else do you want me to say? I. Want. To. Fuck." She said, staring him in the eyes as she said it. "We have the whole house to ourselves for a week! We could fuck right here in the living room! And you don't want that?"
"It's not about that. You're never this pushy about this stuff, or this angry, even when I say no."
"Well yeah, I'm experiencing puberty and all that stupid stuff they talked about in health class." Komaru said.
"Really?"
Komaru grabbed her chest. "Did you not notice my boobs?!"
Makoto bit his finger a bit as he blushed. "No..."
"Liar." She said as she grabbed one of his hands and placed it against her chest.
"Hey, it's not my fault I haven't noticed! I've been busy..."
"Can we pleaaaase just have sex? And then you can do your homework and junk?" Komaru pleaded.
Makoto crossed his arms. "First I finish my homework, then I'm yours for the rest of the week. How does that sound?"
"You…promise?" She asked, a smile appearing on her face.
"Of course, heck, I'll even make us dinner tonight."
Komaru thought it over, and then nodded. "Fine. But please get it done fast!"
Makoto then took the entire rest of the night to finish his homework. The thought of what he had promised barely even registered as he took one step from his desk to hsi bed and collapsed, sleeping straight until six AM when Komaru woke him up. However the way Komaru woke him up was by trying to give him a blowjob, her mouth over the head of his dick as his eyes opened.
"Huh, wuh-" Makoto grumbled as he barely registered the pleasure of Komaru awkwardly working her tongue around his cock. Komaru gently stroked his shaft as she moved further down, even though her back hurt a bit from the angle. Makoto sat up a bit before being forced to fall back. "Komaru-"
"Yesh~?" She asked sweetly as she continued sucking on him. Her brother couldn't finish before he involuntarily came into his little sister's mouth, surprising both of them. Despite her surprise though, she swallowed it all up, feeling it slide down her throat as it all came flooding out. She never quite got used to the taste but either way she drank every drop. Once it was done, she leaned back and wiped her mouth. "Morning~!"
"Morning..." Makoto trailed off as his eyes closed again.
"Come on! Get up! It's time to fuck!" She shouted as she crawled on top of him.
"I can't get up if you're on top of me..." he slurred. Komaru ignored him as she started to stroke his now flaccid dick. Makoto's eyes suddenly shot open and his hips bucked. "Overstimulation, overstimulation!" Komaru continued to ignore him as she could already feel it beginning to stiffen again. Just laying there and taking the moderately painful handjob, Makoto looked over to Komaru's smiling face.
Komaru looked back at him, and the smile fell as she saw his pained expression. "Oh…are you actually in pain?"
"Yes!"
"Oh…sorry!" She said as she finally got off of him, but still continued to stare at his semi hard dick.
Makoto took a quick shower as he tried to clear his thoughts. Somehow he would have to keep Komaru from actively hurting him again, but how? The strangeness of the situation dominated his thoughts as he stepped out of the bathroom in just a towel.
The girl quickly ran up and snatched away his towel in one quick motion and gave his ass a small slap as she ran past.
"Ah, hey! ...I need that!"
Later, Komaru was busy doing the dishes as Makoto was pulling out the chairs and mats to sweep. After glancing at Makoto, she quickly sprayed her white shirt and cried out.
Makoto bashed his head on the chair as he looked up. "Gah, are you okay!?"
Komaru turned to him, the see-through white shirt now clinging to her bare breasts, her nipples poking through prominently. "I accidentally sprayed myself…"
"Well, be careful. That water can scald you," Makoto chastised as he went back to cleaning, while rubbing the bruise forming on his head. "Sheesh, my luck some days..."
Even later on in the day, the two of them were cleaning the bathroom, with Komaru on shower duty. With her shirt still wet to the point it was getting uncomfortable, she decided to just slip it off, and started scrubbing the side of the tub, the aggressive movements causing her breasts to sway back and forth.
The motion instantly did its job, distracting Makoto. "Uh, Komaru, your shirt."
"Yeah? What about it?" Komaru asked, hiding a smile.
"Aren't you cold?"
"No." Makoto shrugged and went back to his work. Komaru was happy it worked, even if for just a moment, and continued scrubbing.
After a bit of silence, Makoto spoke up. "So, how's school?"
"Boring. How about you?"
"Stressful."
"Understandable." Komaru answered as she stood back up, and moved to where her breasts were almost right next to Makoto's face.
"Uh, Komaru?"
"Yep?"
"Why are your boobs in my face?"
"Well you don't seem to acknowledge them unless I do that." Komaru said flatly as she resumed cleaning.
"Hey, that's not nice-" Makoto chastised.
"Sorry not sorry."
Makoto sighed loudly. "Okay, what do I have to do to make you not mean?"
Komaru turned and flicked him in the forehead. "Fuck me. When did you get so dense?"
"Well, how? You seem to want this way more than I do."
"Did you really just ask 'how do I fuck you'?"
"I mean, like, position. Look if you're just gonna be mean about this too then I don't wanna-" Komaru grabbed his collar and yanked him into the living room, throwing him against the couch and quickly working on undoing his pants. Makoto could only watch as Komaru's sudden strength completely overtook him. He knew she was going through puberty, but did every girl get this aggressive!?
The girl yanked down his pants and boxers, tossing them aside as she started stroking his cock. "This is the position I want. You sit like this and I'll do the rest, okay~?"
Makoto gulped, his cock twitching a bit with her sudden affection. "O-o-okay!"
Komaru gently played with his cock until it was at full mast, and then stripped down the rest of the way before she climbed on top of him, throwing her tits in his face for a moment before lowering herself down on his cock, feeling the head of it enter her. Makoto let them rub against his face, realizing how soft and warm they were. Komaru was right, he was a moron for not seeing these before! Komaru lowered herself more and more, until she was sitting on him completely as his entire dick rested inside her. Makoto moaned into her chest as he laid back and practically melted under her. "Komaru~"
"M-Makoto!" She cried out as she lifted her body up and then slammed it back down, her breasts jiggling around as she did so.
"You-you're doing great!" Makoto praised through his moans. Komaru could only moan as she felt pure carnal desire overtake her entire body as she thrust her body up and down on his own, feeling his cock throb inside her as her body clenched tightly around it. "K-K-Komaru, I think I'm gonna cum-"
"Yesssss~!" She moaned and as if the word set her off, she came, spraying cum hard onto Makoto's pelvis, covering him in her fluids as she emptied everything she had inside of her. As Komaru rested on his pelvis, Makoto came as well, giving her pussy the largest load it had ever experienced as his entire body shuddered under her. "Holy…fuck…" Komaru said into his ear as she leaned over against him, trembling.
"Do you feel better?" Makoto panted as he reached around to grope her ass.
"V-very…" She moaned.
Yet, not even an hour later, she was poking his back as she pestered him for more even as they continued to try doing their chores.
Makoto let out a long groan as he mopped the kitchen floor. "Geez, guys need more recharge than girls y'know..."
"Then later?" She asked.
"Sure," Makoto replied even as Komaru had to cross her legs from lust.
Yet even after he was done, with the chores finally done for the day, he sat on the couch and started watching TV. "Now?"
"Komarruuuuuu, my favorite show is on!"
"Don't caaaare, fuck meeeee~" She said as she stood in front of the boy.
"After the show!" Makoto protested as he leaned over to watch from around his sister.
"You promise?" She asked.
"Yes! Now move!"
Komaru sat down next to the boy, and started watching the show with him. She had no idea what was going on, but it didn't really matter as she soon stopped paying attention and slowly moved her hand over the boy's dick. Makoto smacked it away without even looking, thoroughly entranced in the adventure of some wimpy boy with a mecha on the television. Komaru didn't let up though, and forcefully pushed her hand inside his pants and rested it calmly on his dick.
Makoto squirmed a bit, but as two giant robots did a synchronized combat routine to defeat some giant blobby thing on TV, he couldn't pull his attention away. With her hand still in his pants, the girl started to slowly stroke the organ, feeling it harden even as Makoto's attention was on the TV. Makoto suddenly jumped up and cheered as the final blow landed, and a large cast of characters smiled in joy. The girl quickly pantsed Makoto when he stood up.
"Yeah!" her brother cheered, ignoring his now pantless state as he sat back down on the couch.
"You…really like this show don't you?" She asked as she silently used her feet to push his pants and boxers off completely and away.
"Yeah, it's amazing! You should watch it with me someday, front to back!"
"I'd rather watch your front and your back." Komaru said.
"Can you stop for like five minutes?" Makoto bemoaned.
"It's kinda hard to stop when you're…kinda hard~" Komaru joked as she gestured to his exposed dick. Makoto blushed and covered up, continuing the show until the final credits rolled as he wondered where his pants had gone. "FINALLY! Now?!" She asked.
"Yup! So, what do you want this time?"
"You decide this time."
"I have an idea!" Makoto declared as she stood up and began taking off his shirt. "Turn around, and get up on your knees."
Komaru did as she was told, growing excited for what Makoto had planned. Makoto got fully naked and suddenly stepped forward, pushing Komaru too and making it so that her chest and arms dangled over the back of the couch as her butt stuck out. Then, he grabbed the hem of her panties and pulled them down her legs and off of her body entirely, leaving her in just her shirt and skirt.
The girl shuddered violently as she felt her dripping pussy eagerly awaiting him, and she couldn't help but shake her hips a bit. Makoto tapped the head of his cock against her ass a few times, smiling to himself. "Ready~?"
"YES! PUT IT IN ALREADY!"
"Hmm, I dunno, you don't sound like you want it that much~" Makoto teased. Komaru forcefully shoved her body back against his penis, feeling it poke against her, which made her shudder even more. Makoto finally obliged, gripping his little sister by the hips and thrusting directly into her, burying half of his cock inside of her immediately.
Komaru cried out in glee as his dick entered her once again. Makoto immediately got to work, grabbing Komaru's hair and yanking her head back as his other hand gripped her hips to stabilize her as he hammered in and out of her pussy.
"Y-yessss!" She cried out as she felt that desire being fulfilled again, feeling it slide effortlessly in and out of her as she giggled and laughed and moaned.
Over and over again, his little sister's body jolted and shook as he slammed in and out of her, every thrust eliciting a loud moan or whimper from her that made him desperate to go even harder on her.
The girl's speech became a blur of moans and groans and other noises as she felt her body rock and shake with every movement of her brother's body against her, and soon enough, she came once again, spraying more of her juices onto him, the couch, and the floor.
Makoto pulled out of her and suddenly spun her around, laying her on her back on the couch. Then, even before she had recovered, he climbed on the couch too and positioned one knee beside her on both sides, letting his still-erect cock brush against her modest breasts.
Still panting, Komaru looked up to see his dick was now touching her breasts. "H-huh?" Without responding, Makoto roughly grabbed her tits, groping and molding her as the head of his cock began sliding in between them.
Komaru wasn't really sure what he was doing, but feeling his hot, hard cock against her soft breasts made her body lurch, and the expression on his face made her feel amazing. She let out a long, steady moan as she felt his dick fit perfectly in between her moderate tits, followed by him beginning to slowly pump into them.
"Th-this is…weird…" She voiced her opinion aloud, and then gasped as his dick accidentally bumped against her chin.
"That moan tells me you like it though~" Makoto teased back as he squished her breasts together as tightly as they could manage, forming a complete seal around his cock as it poked against her neck and chin.
"Y-you seem to, too…" She said before moaning again, reaching down and slipping a finger inside herself, feeling his cum that rested inside her as she thrust the finger in and out. His pace quickened as she began masturbating, his two-handed grip on her chest letting him thrust roughly in and out of the cavity between her tits as his breathing grew.
Komaru moaned loudly as her body continued to shake, her hand movements speeding up rapidly as she could feel that satisfying pressure building again. Her brother finished first, giving both of her nipples harsh grasps as his cock began spurting line after line of semen onto her face, painting her adorably lewd expression white as she only fingered herself harder and harder to the feeling.
Komaru, not used to the sudden organic face paint, cringed as it splayed on her, but she kept going, and just as Makoto ended, she started, moaning loudly as she sprayed hard onto the couch once again, shouting "AHHH! M-MAKOTOOOO!" as she finished.
Makoto collapsed on top of his sister, smothering her face in his chest despite the 'glazing' he gave himself in the process. A loud moan sounded from him as he tried to wrap his legs around her upper body for warmth and comfort.
"Wow…" She moaned. "Thank you~"
They stayed like that until they eventually passed out, naked and cuddling on the couch, until the next morning when Makoto peeled them apart and got them ready for the day. It was breakfast when Komaru tried to start things off again.
"Heyyyyy, we still have a couple days until they get back. Soooo, what do you wanna do today~?" She asked in her (weak) seductive voice.
Makoto swallowed another spoonful of Sayaka Maizono's Sugar-Stacked Surprise (not only because it was the sibling's favorite idol, but because Komaru read somewhere that it actually made guys hornier, and so she insisted on Makoto eating more of it). "What do you mean?"
Komaru paused to blink. "Sex." She said, not thinking she needed to specify.
"Well, I figured that, but usually when you ask me something like that you actually have something very specific in mind."
"W-well…there is something, but I'm not sure if you'd be…up for it." She said shyly, her face turning slightly red.
Makoto was a bit taken aback. Usually when Komaru had these ideas he woke up in a dark room a few minutes later, so the fact she was asking him was surprising. "What is it?"
"I…uh…" Komaru wasn't sure why she felt so shy asking him about this, "…I saw this thing…online…with…rope?"
Makoto's mind was immediately filled with horrific images of Komaru lynching him for a single orgasm, but he pushed that jump to a conclusion out of his head. "What was it?"
"I was hoping you'd just know what I was talking about so I wouldn't have to explain it." She said, blushing deeply as she became uncharacteristically shy, though she wasn't sure why. "Like…you get naked…and I…tie you up?"
Oh, that's nicer than I thought, Makoto thought. "Oh, that's nicer than I thought."
"Wait…really?" She asked with surprise.
"Sure, I'm up for it. But you know you need a safeword for that kind of stuff, right?"
"Safe…word?" She asked, tilting her head.
"It's a thing one person says and the other person has to stop no matter what. It would've been useful at some other points..."
"Why didn't you bring it up before then?" She asked with a raised eyebrow.
"I…just learned about it recently. I'm as new to some of this stuff as you are."
"Right. Okay! So…if we have a safe word we can do it?"
"Sure! How about the safe word is…Sayaka?"
"Pffft." Komaru scoffed. "What, do you have a thing for her or something?" Komaru teased.
"And you don't?"
Komaru's smile immediately fell as she blushed. She straightened up and cleared her throat. "Right. Anyway! I have the rope already, I had mom buy me some for a 'school project' and she surprisingly didn't question it."
"You…what?"
"Yeah, I dunno. I guess she's really trusting." Komaru said.
"Komaru, that's super dangerous, I have money, you could've asked me. I mean, I swear, why would you thi-"
In the blink of an eye, Komaru removed her panties, bundled them up, and shoved them into his mouth, gagging him. "Alright, I'll go get the rope, you start getting naked!" Makoto gagged a little on her panties, but surprisingly even to himself, didn't remove it as he stripped completely naked there in the dining room.
As Komaru returned, she was surprised to see the panties still in his mouth. Either way, she dragged his naked form into the living room and produced the rope. She briefly glanced over at the window facing the neighbor's house, which Makoto seemingly hadn't noticed, and smiled as she had an idea. Makoto let her tie his hands behind his back, forming a knot that went down in a long strand to tie his feet together as well; this forced him to stay on his knees while also preventing him completely from resisting her.
Komaru removed the gag, and eyed him suspiciously. "You looked like you were enjoying that…"
Makoto immediately blushed and turned away. "Be quiet!"
"Alright well, I've got a special place I want to position you~" Komaru said.
"Yes?"
"In front of the window!" Komaru said as she shoved his body up towards the window, where Makoto was just tall enough for his dick to be in full view as she immediately began stroking it.
Makoto gasped as he moaned, struggling a bit against his bindings and Komaru's grip. "Hey wait!"
"Hehehehehe!" Komaru giggled as she slapped the boy's ass hard, frantically moving her hand up and down to bring the boy to full mast, an erection completely visible outside. Komaru had to hold him in place as he kept squirming, the stinging in his ass melding with the pleasure in his cock in a way he couldn't handle without loudly moaning. "Oh hey look! The neighbors are home!" Komaru said as she watched them pull up to their house.
"WHAT!?" Makoto panicked as he saw a single mother stumble out of the car with a mousey girl, about his age, who wore thick glasses and carried a thick book in front of her like a shield.
"I wonder if they'll see you, all tied up and completely exposed, see your cock throbbing as you have no choice but to sit here and take it~" Komaru whispered as she squeezed his ass and gently nibbled on his neck.
Makoto desperately wanted to screech Sayaka, both at how overwhelmed he felt and out of genuine fear of either one of those ladies turning and seeing such a lewd sight going on between the neighbor's kids, but something kept him from doing so. Instead he could barely make out both of them stepping inside of their house, and after a few moments, movement in front of the window on the top floor.
"Oh look at that…if she opens her window, she'll definitely see you~" Komaru asked, taking a surprising amount of pleasure in her sadism, moving down to stroke Makoto again and make sure he was still completely hard for when the time came. Makoto couldn't help cumming when she said that, spurting onto her hand and part of the curtain as his entire body shuddered.
Komaru watched as just as he came, the other curtain opened, revealing the small girl they'd seen earlier. As soon as she spotted the two, and saw Makoto tied up naked his dick spewing, she immediately went wide eyed and watched in fascination.
"Sayaka, Sayaka!" Makoto panicked as he locked eyes with the girl, whose eyes widened behind her glasses as she gasped.
Komaru let him go and walked in front of him, but not to the point where he was no longer exposed. The girl was still staring wide-eyed in awe at the boy and particularly his dick. "What?" She asked in annoyance.
"SHE IS WATCHING!" Makoto panicked as the girl…giggled a little?
"Yeah, so?"
"WHAT IF SHE TELLS SOMEONE!?"
"You really think they'll believe her?" Komaru asked.
"WHY WOULD I RISK THAT?" Makoto freaked out as, over Komaru's shoulder, he saw the girl wave to him.
"Man, you're such a wuss!" Komaru moaned. "Can we please just continue? I'm standing here being horny, see?" She said as she raised her skirt, not only reminding Makoto that she wasn't wearing panties, showing off her wet pussy, but also exposing her ass to the girl.
"I-I-I-" Makoto's mind turned to mush, both because of Komaru's pussy and also because the girl hadn't run away to call the cops on them yet.
Komaru finally turned back, and saw the girl staring at her instead. When she realized the girl had been staring at her ass, she blushed, but smiled. "You know…we could just give her a show, if she's so keen to watch~"
"I-I guess..." Makoto trailed off as he watched the blushing girl bite her lower lip while twirling one of her braids.
With a smile, Komaru undid her skirt and let it drop to the floor, before removing her shirt and bra and well, quickly leaving her naked. She bent over and shook her hips for the girl watching, also causing her breasts to shake in front of the boy's face. Makoto gave her chest a few tentative kisses as the girl let out a gasp, a whole new world being opened before her eyes.
"I-I could've gone with a warning!" Komaru said hypocritically.
Makoto pulled back and raised an eyebrow. "You're trying to draw a line now?"
Komaru sighed and walked over, grabbing his head and burying it between her legs as best she could. "Lick." Makoto grinned to himself for his small victory before doing as he was told, running his tongue up and down the length of her cunt as she moaned at the stimulation. Komaru moaned, her body shivering as she reached down and patted his head, whispering "Good boy~"
The praise and pats made him blush even harder as he plunged his tongue inside of her, and the girl in the other house suddenly discovered that touching her chest in certain ways felt amazing when she was watching this kind of stuff.
Komaru unfortunately wasn't able to see the girl, even if she turned back, so she focused on pushing herself further against Makoto as she could already feel a climax approaching. She could just feel the girl's eyes on her ass, which only aroused her further. She never would've guessed someone watching would make it so much more…hot.
The young girl put her hands under her shirt to rub her nipples as Komaru finally released, squirting inside of Makoto's mouth as he continued licking and prodding at her until she almost collapsed on top of him.
"H-how does that taste~?" She asked, now struggling to stay on her feet.
"Still wonderful~" Makoto shot back, before completely focusing his attention on the girl trying frantically to pleasure herself in the window. "Uh, Komaru, I think she's trying to masturbate."
"Heh. Maybe we should invite her over to show her how~" Komaru said as she moved around behind him. "For now, let's show her what she was missing~" She pressed her body against his, her breasts squished against his back as she reached around and started to jerk him off.
Makoto let out a loud moan as his penis was stimulated anew, pre already leaking out of the tip as he couldn't resist making eye contact with the girl, which made her clearly moan a little as she continued rubbing her nipples under her shirt.
"Look at her. She's probably so sweet and innocent and now we're tainting her~" Komaru said as she stroked him to full mast once more as moved her body around, rubbing her hard nipples against his body.
He couldn't believe what he was hearing even as his body reacted, a hard shudder encompassing all of him as his cock quickly approached another release.
Feeling him react violently to that, she smirked. "What, do you like corrupting youth? Because you certainly enjoyed doing it to me~" She whispered as she gently nibbled on his ear while frantically moving her hand up and down.
Something about the way she purred was enough to immediately finish him, a very small amount of cum leaking from his tip even as his cock pulsed furiously within her grasp.
Feeling satisfied, Komaru looked out the window once more to see the girl still only playing with her chest. She sighed and walked up to the window, standing right in front of it as she smiled, waiting for the girl to meet her gaze. Once she did, she lowered her hand down, and placed her fingers against her pussy, slipping one inside with a moan as she started masturbating for the girl to watch.
Makoto took the chance to rest as the girl immediately took to the impromptu 'lesson,' quickly stripping herself naked in the middle of her room and trying to copy what she could see of Komaru's actions.
Nodding to the girl, she spread her legs as much as she could and thrusted her hips forward, doing her best to spread her lips as she thrusted the finger in and out of herself with loud moans.
Both the siblings watched in anticipation as the girl reached down with one finger and slowly, gently inserted it into herself. Her face contorted until it settled on a look of pleasure, and she smiled at the two as she slowly began moving her finger in and out.
"Bingo~" Komaru said as she thrusted the finger rapidly in and out of herself, looking over her shoulder to wink at Makoto behind her.
Makoto blushed a little as he couldn't help but feel aroused by the sight of the two girls exploring their bodies, the small one in the window even appearing to add another finger as she picked up the pace.
Komaru finished first, exploding onto the floor with fervor as she moaned nearly falling backwards onto Makoto. She managed to stay on her feet as she finished, but soon after, she turned to Makoto and smiled. "Ready…for a grand finale?"
"Always~" he purred to her, the fact that his cock was already erect again a perfect sign that any apprehensions he had had left him by now.
"Let's make it loud~" She said as she straddled him and pressed his dick against her now dripping pussy.
Makoto didn't intentionally moan loudly, but that's the effect that came out from feeling Komaru take his cock inside of her as the girl in the window learned how to rub her clit as well.
Komaru groaned as she rapidly inserted more and more of the boy's cock inside her until it fully enveloped him. She looked back to see the girl watching as she frantically fingered herself, and she smiled, before turning back to him, and kissed him, immediately shoving her tongue inside his mouth.
Makoto reciprocated as the two siblings, lost in pleasure, just barely missed the girl having the first of many orgasms she'd experience just that day alone.
Komaru pulled back momentarily to whisper a surprisingly wholesome "I love you, Makoto…" as his saliva dribbled down her chin.
"I love you too~" Makoto moaned back before suddenly lunging forward and nibbling at her neck.
"Ahhhhh!" Komaru moaned, already forgetting about the girl for the most part as she became lost in her own arousal as she started bouncing her body up and down on the boy's cock.
Makoto once again came first, nothing coming out of his dick as it could only spasm intensely inside of his little sister.
Komaru on the other hand wasn't quite down, and held onto her brother tightly as she bounced on his still somewhat hard dock a few more times before she too finally came, spraying juices onto his pelvis as she shoved his head away from her neck so she could kiss him.
The girl in the window could figure out that they were 'done,' and so she closed the blinds and decided to spend some more time 'playing,' as she would call it. Meanwhile, Komaru finally got off of Makoto and the first thing out of his mouth was the question- "Can you untie me now? My knees hurt."
