After School Combo

One Afternoon…
3-E Campus

The class was busy writing down notes from their English lesson, Irina Jelavic scribbled on the chalkboard. "Alright, make sure you all get the conjugations right. I'll be quizzing you on this tomorrow."

Turning around, the busty blonde assassin, now a schoolteacher, looked around at her students quietly writing into their notebooks. The silence gave her a moment of reflection. A year ago, if someone had told her she'd be teaching English to a class of dropout students she would have laughed…and probably have put a bullet between their eyes for the insult. Now she felt a wave of contentment as she looked at the children. Perhaps later, after she figured out a way to bag that octopus, she could retire from the assassination gig and start teaching for real.

'Although hopefully I'll teach students who won't call me Bitch-Sensei…' she lamented.

The blonde's eyes scanned the room. Most of them had their head down, save for a few. Karma, the slacker genius, was lazily looking up at the ceiling while he tilted back in his chair. She was used to his laidback attitude though. Okajima, the perverted one of the bunch, kept looking at her longingly. The woman rolled her eyes. 'If he put as much effort ogling me as he did in his grades, he wouldn't even be here…'

However, when her eyes scanned over to a certain blue-haired young man, she noticed that Nagisa was also looking at her, his gaze focused primarily at her chest. But when her eyes found his, he blushed and looked back down at his notebook. This made Irina raise an eyebrow. She had noticed that Nagisa had started developing wandering eyes for when he thought she wasn't looking. And every time she caught him staring, he'd look away almost ashamedly.

'Hmm…what to do? Okajima is one thing. But if Nagisa keeps staring at me like that, it could become a problem.' Turning away and walking back to the desk, she frowned when she realized why Nagisa might be becoming infatuated with her. 'I guess I had this coming ever since I frenched him when we first met…' It wasn't the worst thing Irina had done and she'd done it in order to acquire what information the boy had learned about Korosensei but in hindsight she was starting to realize that wasn't exactly the smart move to make. 'Then again, I'd thought I'd have the Octopus dead by the end of the day, so I wasn't thinking about the future…'

Sitting down at the desk, she looked over at Nagisa, who was again staring at her before looking away. 'Yeah, I'd better think of how to best resolve this. Otherwise this might become a creepy problem in the future.' Having thought of that though, she wondered what her options were. 'This isn't something to really bring up with to Karasuma. And I'll be damned before I got to that stupid Octopus for help.'

Irina turned her back to Nagisa and could feel his gaze on her. She didn't know what to do but she knew a problem when she saw it. This was going to be difficult to handle. 'On second thought, maybe I won't retire to be a teacher if they're all going to be perverts.'

Later that day…
Shiota Residence

Nagisa's mother, Hiromi, was busy in the kitchen preparing dinner when she heard the front door open. "I'm home!" shouted the voice of her son.

"Oh hi, Nagisa! How was school?" Setting down her kitchen knife, Hiromi turned towards the hallway and saw her blue-haired son pass by the doorway of the kitchen.

To her dismay, her son merely gave a curt "Everything was okay, I'll be upstairs doing my homework," before heading up to his room.

Sighing, Hiromi turned back to her cutting board and thought about her son's behavior. Lately things had been…strange between them.

At first, Nagisa seemed to be doing better now that he had earned his independence from his mother. After that night at the Class-E classroom where she tried to force her son to burn the place down to the ground, Hiromi had stopped trying to be so controlling for her son and had did her best to make up for her horrible behavior. Their relationship was certainly better than it had been.

And yet…

Hiromi set down the knife and frowned as she thought about the matter more. She had started to notice that Nagisa was acting weirder around her lately. During meals or when he was helping her out around the house she'd notice him acting flustered, unable to look her in the eye.

"Have I done something to upset him? Should I sit him down and ask him what's wrong?" she asked herself. Young boys were difficult even at the best of times so she knew she needed to weigh her options. Part of her wondered if she should go and ask one of Nagisa's classmates about his recent behavior. "Perhaps that Akabane kid can tell me what's going on with him?"

She dismissed the idea almost as quickly as it came to her. Hiromi had made a complete ass out of herself when she'd confronted Nagisa's "bald" teacher. More than likely, if she approached one of Nagisa's classmates they would be so intimidated by her that they would either refuse to talk or run like the wind away from her.

"Oh damn it all, what should I do?" she lamented, lifting the cutting board to slide the cut veggies into the boiling pot on the stove. All the while, she had no idea that Nagisa was staring at her from the corner of the kitchen's entrance, his blue eyes staring at her shapely curves before fixing their gaze at her rear end…

The Next Day…
Supermarket

Pushing a cart down the aisle, Hiromi Shiota continued to think about her situation with her son. "Hmm…the more I think about it, the more I just keep spinning my wheels," she mused to herself while grabbing a few cans of veggies from the shelf. "I guess I'll just have to sit him down and ask him. I just hope that he doesn't get angry or scared that I might be upset with him…"

So lost in thought, Hiromi didn't realize she'd accidentally bumped into someone until she heard a "Hey! Watch where you're going!" from her unintended victim after she'd been knocked to the ground. Snapping back to reality, Hiromi gasped in horror and quickly walked around her cart to help them up. "I'm so sorry! Are you okay?"

When the tall blonde woman stood up and huffed, Hiromi was taken aback by her appearance. Clearly a foreigner by her soft skin and natural blonde hair, she looked like a supermodel that Hiromi would see on the sides of busses and advertising billboards. Her curvy body and ample bosom made Hiromi a little envious and it made her a little self-conscious of her own homely appearance. 'What's a woman like her doing in a place like this?' she wondered to herself.

"I'm fine. I've endured worst," The woman brushed off the dirt on her miniskirt. "Least I didn't get blindsided with slimy tentacles this time…"

"Huh?" Hiromi wasn't sure if she heard the woman correctly.

"Never mind. It's a long story. Huh?" The woman got a good look at Hiromi and quickly she recognized her. "Aren't you Nagisa Shiota's mom?"

Hiromi gasped, partly in shock that this beautiful woman knew her son and partly in fear from some of the implications that ran through her mind. "How…how do you know Nagisa?" Instantly several scenarios sprung to life, none of them good. 'What's Nagisa doing with a woman like her? Is she…is she one of those Soapland girls that like to seduce young boys?' The image of the woman naked and rubbing her body all over her son made her want to faint.

The woman didn't know what was going through the woman's mind but she had a good idea that the woman had the wrong impression of her. "I'm his teacher. My name's Irina Jelavic. I teach English at Nagisa's school."

That dirty thought popped out of her head like a balloon. "Oh! You're Nagisa's teacher?" Now that she thought of it, she did recall seeing the woman the restaurant that Nagisa and his classmates at E-Class had set up during their school festival. 'Guess I let my imagination run away with me for a moment.' A knot of shame twisted inside her stomach for being so judgmental. 'I suppose I haven't quite stopped flying off the handle like I thought I had. But what's a woman like her doing as a teacher? With looks like that she could have any job she wanted.' At first she wondered what the woman was doing here and not at the classroom before remembering that today was not a school day.

Picking up her basket, Irina huffed before she eased up on the woman. To be fair, she hadn't planned on being a teacher longer than a day or two. Her plans fell to pieces once the unkillable Korosensei had sniffed out her plans to kill him. However, realizing that she had Nagisa's mother in front of her, it seemed like a good idea to bring up the boy's strange behavior. "It's fine. Anyway, do you mind if I ask you something? It's about your boy."

"Nagisa? What about him?"

As Irina explained the odd way Nagisa was behaving, Hiromi soon realized that the woman had discovered the same problem as she had. "I see…so he's been acting weird around you too…"

The two women started to walk together throughout the grocery store while discussing Nagisa's strange behavior. "So you don't know what's causing him to act like that either?"

Shaking her head, Irina sighed. "Not really."

"I guess I'll just have to sit him down and ask him."

Again, Irina shook his head. "You don't know teenagers really well, do you? If you try to corner him and squeeze an answer out of him without knowing what's going on, he'll just clam up and keep himself from talking. Your house is nearby, right?" Irina had committed all the student's homes to memory in case she needed to come to their aid in an emergency after the Reaper incident.

"Yes, why?"

"Well, you're his mother and I'm his concerned teacher. Let's do some snooping in his room."

Hiromi couldn't hide the concern on her face. She had just met the woman and the prospect of letting the beautiful woman into her son's room was a dubious one. But Irina had a point. If she wanted to get to the bottom of whatever was going on with her son then she needed to start digging. "Okay. I suppose a quick look in his room can't hurt. Nagisa's out hanging with Karma Akabane so he won't be home for a while."

"Alright. Then it's settled." This wasn't how Irina wanted to spend her day off from teaching the students but if it helped them find out what was wrong with Nagisa then she could think of worst ways to spend the day. 'Besides, sneaking into a young man's room is always a ton of fun…'

Twenty Minutes Later…

The door to Nagisa's room opened and the two women quietly stepped inside. Hiromi started to sweat bullets as she looked around, hoping that they wouldn't find anything that was dangerous or incriminating for her son. She was started to hate her decision to let this woman into her house but it was too late to back out now.

Nagisa's room wasn't anything special. Irina thought it was fairly average for a teenager. "Hmm…I don't want to go rummaging through everything. Let's check his closet."

Hiromi nodded and walked over to it, sliding the closet open. The women peeked inside but found nothing dubious within. "Phew…"

The blonde English teacher spotted Nagisa's backpack and took a quick peak. Like Hiromi and the closet, there was nothing hidden inside that would explain Nagisa's recent behavior. "Not even a nudie magazine. I'd say that's weird for even a young boy."

The dark-haired mother ignored the comment and turned towards her son's desk. Spotting a small notebook sitting atop a math book, she flipped it open. "Korosensei Weakness #1: When he tries to look cool, his weaknesses show. Korosensei Weakness #2: Panics easily. Who's this Korosensei?" she wondered aloud to Irina. "Some sort of videogame boss monster or something?"

Irina felt very hot under the collar and tried to keep a straight face. She'd completely forgotten that the parents of Class 3-E knew nothing about Korosensei or the threat he faced to the planet. Suddenly she realized that if they kept snooping through his room, Hiromi might accidentally find out the truth that her son was being trained to become an assassin. 'Rghhh! This is why I hate dealing with moms! I hope Nagisa didn't keep anything that'll outright give him away.' She'd be in trouble if Hiromi found one of the class's Anti-Sensei knives or a plan written down to kill the octopus."Um…yeah, I think I've heard of Korosensei before. The boys were talking about him in the back of class, now that I recall correctly. He's supposed to be some octopus boss monster of the newest RPG game or something."

"I see. Well he has been hanging with that Akabane kid a lot. He's probably been playing the game with him. Here, let's check his laptop. Maybe we'll see what's going on with his search history."

The mother nodded and opened her son's laptop. Thankfully Nagisa didn't make his password hard. Irina wisely deduced that his password would be "KOROSENSEI" since she knew what an impact that the octopus superhuman had on his students. As soon as Nagisa's laptop opened up to the spying duo, Hiromi clicked on her son's browser history and opened up the last few pages of it.

And in the very next second the two women blushed hard when they saw what Nagisa had been looking at.

'Well never fucking mind! Looks like he's a normal teenager after all.'

Hiromi put a hand over her mouth to cover her gasp, eyes going wide when she saw the multiple tabs of pornography that were displayed before her and Irina. "Oh…oh my…" The mother knew she shouldn't be too surprised to know her son looked at porn but…it was still shocking nonetheless. "Is this why Nagisa's been acting weird? He…he isn't becoming addicted to internet porn, is he?"

"I hope not. That's not a conversation with him I think either of us are ready to have." Irina leaned forward and took a closer look at the porn on the screen, going from tab to tab. 'Should probably just bring this to the Octopus. Although I'm not sure even he's prepared for something like this if Nagisa has become addicted to…huh?' Irina blinked as something clicked in her mind the more she looked at the porn on Nagisa's laptop; specifically, she noticed what type of porn it was. "Ah, now I get it."

"Huh? Get what?"

Standing up straight, Irina gave a sigh. "Nagisa's acting weirdly around us not because he's become addicted to internet porn. It's because…well…we're his type."

"What?"

"Take a look." The blonde assassin clicked on a few websites to prove her point. "MILFS Galore. Mature Hotness. Mothers Gone Wild." She decided to close the laptop; there was no reason to keep showing Hiromi her son's porn now that the woman got what Irina was telling her. "Nagisa's become attracted to mature women. That's why he's become so flustered and nervous around the two of us."

The blush on Hiromi's face grew brighter and her ears burned with the knowledge that her son was attracted to her. "My boy is…attracted to older woman? How'd he get like that? Did some older bimbo make out with him when he was distracted or something?"

That statement made Irina stiffen as if she'd been struck by a bolt of lightning. A flash of realization hit her and she realized just how on the mark Hiromi's statement might have been. '…Fuck! Is this because I kissed him when we first me?!'

Irina's memory rewound to her first day at the Assassination Classroom. The moment Korosensei had left to go grab something for Irina overseas, the assassin had dropped her bubbly attitude and shown her true colors to the children. And to show just how effective of a seductress she was, she cozied up to Nagisa and promptly stole his first kiss, hitting him a 30 hit combo. She then pulled the dazed, clearly disoriented Nagisa into her embrace, cushioning his head on her soft, pillowy breasts.

Suddenly it didn't feel so bizarre that Nagisa would become attracted to older women if his first romantic experience with a woman was a blonde assassin with a body that could stop a clock. The English teacher gave Hiromi a quick glance and she could definitely see why Nagisa was attracted to his own mother. 'Maybe the reason he's only now starting to act like this is because he's mended the relationship with his mother and sees her more than just as someone trying to control his life now. He's seeing her not only as his mother but as a woman too. He's no longer trying to hide who he really is so whatever checks he's placed on himself have slackened,' she deduced.

Still blushing, Hiromi sat down on Nagisa's bed and put her head in her hands. She felt dirty knowing that her son found her attractive. "What do I do?" she asked Irina, who didn't really have an answer of her own.

Crossing her arms, the assassin thought about how to handle the situation. Feeling responsible for causing Nagisa to develop such a fetish, Irina tried to think of a suitable way of getting Nagisa to control his desires. If left alone, there was a good chance that the young man might do something stupid. He'd clearly expressed desire in both Irina and his mother. They needed to do something before Nagisa's problem escalated out of control.

'Hmm…think, Irina, think…'

Putting aside her job as a teacher, Irina thought of this as if Nagisa was a target for assassination. His fetish was his key problem. And for Irina, the best solution to handling problems was to deal with it head-on.

And for a seductive temptress, there was only one way to deal with a horny man.

Was it wrong? Irina certainly felt the immorality of the option start to weigh on her shoulders. But that was a weight she easily shrugged off. She was an assassin, a killer of men and women. This was certainly not the worst thing she'd ever done in her life. As long as she kept it hidden from Korosensei and Karasuma, she saw no real problem with it.

Now for the other half of the problem: Hiromi.

Sitting down next to the Shiota mother, Irina put on a reassuring smile, putting a hand over hers to help calm her down. "Now don't worry. This is not your fault. It think…it might have been me who caused him to be like this. I…gave him quite the first impression when I first met him. But…" Irina reached for Hiromi's face and tilted her head up with a finger to her chin. "Since I am the one who caused him to be like this, I will accept the responsibility. But…I might need your help."

"H-help?" Hiromi blushed when she realized how close their faces were. She felt like she was going to get lost staring into the blonde's beautiful eyes. "Wha…what do you want to do? What do you want me to do?"

The next few minutes saw the dark-haired Hiromi sitting next to the buxom blonde listening to Irina's proposal. With every word that passed through her ears her blush became intensified until her face was red as Karma's hair. "You...you…you're…serious?! What…what…what kind of teacher are you?"

"A good one."

More minutes passed as Irina kept talking. As much as Hiromi thought the woman's idea was absolutely insane, however, Irina had a knack for persuasion and by the end of their conversation the assassin had brought Hiromi around.

"O…okay…" The mother gulped, her face breaking out with sweat as she tried to process Irina's plan. "I…I suppose that makes sense. Better us than someone else…"

"Exactly. And do not worry. Nobody will hear of this. It will just remain between the three of us. Now then…when does Nagisa get home this time of day?"

"Um…uhhhh…" Hiromi's brain failed herself for a long moment. She was still trying to wrap her head around what she just said yes to. "I think…in a few hours?" She didn't know what was what anymore.

"Okay then. That gives us enough time."

"Time for what?"

That seductive smile on Irina's face returned, making Hiromi blush while rubbing her legs together.

"Why, we're going shopping, of course!"

Hours later…

Nagisa closed the door behind him. The sun had gone down and things had gotten quiet. He'd met up with Karma and Sugino to discuss their next plan to assassinate Korosensei. 'We're getting closer to the deadline. I hope we can make it in time…' he thought worriedly as he took off his jacket, hanging it on a rack before he noticed the lack of noise coming from the living room or kitchen. "Huh? The door was unlocked though." Nagisa took off his shoes and headed further into his house. "Mom? You here?"

His mother's door opened up and the last person he imagined to be in his house walked out. "M-Miss Jelavic! What are you doing in my house?"

The buxom blonde walked down the hallway wearing a black robe around her voluptuous body. Nagisa's teacher smiled happily while pulling her short student into a hug, his head pushing against her soft boobs. "Nagisa! I met your mother this afternoon while at the store. Why didn't you tell me your mom was so nice?"

'Nice…is…subjective…' Nagisa thought as he struggled to breathe with his face smothered by luscious boobs. His senses were overwhelmed by her strong perfume. "What…what are you doing here?"

Nagisa's answer came not from Irina but from a voice behind the woman. "I ran into Miss Jelavic earlier and we started talking." Hiromi walked up beside them, wearing a white robe that covered her body. "We noticed how strange you were acting around the two of us so we put our heads together to find out what the issue was." The mother blushed when she saw the way the young teacher was hugging her son but said nothing.

Taking his head out of his teacher's tits, Nagisa took a deep breath and looked from Irina, to his mom and then back to Irina before he put two and two together. "Did…did you…" His blue eyes widened and a look of horror stretched across his young face while the color was drained from it. "You opened my laptop? But…how did you-" He didn't even need to know how Irina cracked his password. Even if he didn't make the password so obvious, she could still have just asked Ritsu to hack his laptop.

The realization that his mom and his hot teacher opened his laptop and found out about his fetish mortified him. He didn't want his mom to know he'd been having incestuous thoughts about her, especially now that he was starting to see her for the woman she really was and not as a puppet master. "I…I…I'm so sorry!" He pulled away from Irina and bowed low, feeling ashamed of himself. This had to be the worst day of his life. His only solace was that Korosensei wasn't here to make it even worse.

Hiromi stepped in and gave her son a loving hug. "No, it's alright, sweetie. You're a young man. It's only natural that you'd develop interests in women. It's my fault for not seeing it earlier and talking to you about it."

The hug with Nagisa grew tighter as Irina joined in, patting Nagisa's head soothingly to assuage his guilt and fears. "And I'm the one who caused this. You started lusting for mature women after I kissed you, didn't I?"

"…Yes…" replied Nagisa weakly, his head feeling dizzy from both Irina's and his mother's perfume and the way they were both holding him.

"Then we'll take responsibility for your feelings. Come with us, sweetie…" Hiromi said, though she couldn't shake the nervous look in her eyes.

Nagisa was guided towards Hiromi's bedroom. In the middle of the room was a large King-sized bed with dark blue sheets. The women sat the boy on the edge of the bed before Irina took a step back, playfully fiddling with the tie to her robe. "So, Nagisa. I had a long talk with your momma and we agreed that it'd be best to help you curb your fetish before you do something completely reckless." She looked over at Hiromi and gave the nervous mother a wink. Nagisa's mother nodded and started to untie her own robe. "And the best way to do that…is to take on your lust ourselves."

Sitting on the edge of the large bed, Nagisa's confusion turned to absolute bewilderment when his buxom teacher and his mature mother dropped their robes, revealing the lewd lingerie they'd been wearing. "Wha…I...M-Mom…B-B-B-Bitch-Sensei…" he stammered, his eyes widening to their very limit and his face becoming red. He felt faint. Staring at the two women he'd been lusting after wearing such sensual garments made all the blood rush to his head…and then rush south towards his loins. "Why…why are you…" He didn't know what to say; his brain had completely gone blank as he struggled to understand just what was happening in front of him.

Irina blushed a little as she stood in front of her young student in her brand new lingerie. She had taken Hiromi to a lingerie shop after finding out that the mother didn't really have any sexy underwear after she'd broken up with her husband. She'd picked out new underwear for the two of them, since she didn't want to waste time going back to her own apartment to rummage through her wardrobe.

Her huge, voluminous breasts were held by black bands that covered nothing, a single ruffled strip crossing each one diagonally and barely hiding the pink peaks beneath them while her areola was free to see. The "v"-like shape her top formed pointing to her taut stomach and equally slutty panties, held together by the smallest of string and a single line digging into her core. The underwear was just skimpy enough that Nagisa could make out her blonde bush peeking out from the sides.

When Nagisa looked at his mother and took in her appearance, for a moment he forgot that the woman was his mother and mistook her for an underwear model. Her body, while not as elegant and young as Irina's, still had the curves that Nagisa yearned to touch. In contrast to the sinful dark outfit Irina chose to wear, his beautiful mother wore an angelic white three piece. Her bra was little more than a frilly band that could barely hold back her beautiful twins. On her stomach was a garter belt that connected to her fish net leggings. The white underwear she had was near see-through, with a small bow topping it all off.

Nagisa's jaw hung low and he felt his pants starting to tighten. He had no idea how crazy tonight was going to be. "M...mom…" he sputtered, unable to take his eyes off of his beautiful, sexy mother.

His body stiffened as the beautiful lingerie-clad women walked towards him. Hiromi sat by her son's side, her body so close to Nagisa's that he could feel her warmth radiating off of her hot body. His breath hitched when he felt a hand touched his chin, turning his head to face hers. "No need to be so uptight, Nagisa. We're here to help you let out that lust you've had pent up. I can tell how much you wanted me, all those times I caught you staring at me. Tell me, was it because I stole your first kiss?"

"Y-yes…" admitted Nagisa, that kiss being the catalyst for the young man's fetish.

"Then I'll have to give you special care. Just consider this a very hands on sex education legend," purred the blonde seductress, her pink, luscious lips nearing his face.

Nagisa's breath was taken away when Irina pressed her lips against his. His body felt like a bolt of lightning shot through him, taken away from the softness of his teacher's lip. Irina's lips were softer than clouds, a thin, slippery tongue worming into his opened mouth. "Mmmmh!" The boy's brain once again failed to think, only focusing on the softness of her lips and her tongue teasing his own.

When Irina pulled away, she giggled from the panting, dazed expression on the teenager's face. "Well, you look even more aroused than the first time we kissed. If this is anything to go by…" Nagisa gasped when her soft hand palmed the bulge in his pants. While the assassin and teacher part of Irina was disgusted at herself for doing this with the boy, the woman in her was very interested in seeing just how big Nagisa's bulge really was.

"N-Nagisa…"

Snapping out of his daze, Nagisa turned to face his mother. Hiromi reached up and caressed her son's soft cheek, steeling her nerves. "It's okay. I'll take all your pent up feelings. I know you love me more than as a mother. What happens won't leave this room. So…so…" Throwing herself into the deep end, Hiromi kissed her son.

Both mother and son stiffened from the incestuous kiss, feeling awkward as they locked lips. However, Nagisa worked up the nerve to reach up with his small hand and palmed his mother's breast, fingers sinking into her soft boob. 'Nagisa's…touching me. We're kissing and he's touching me. I…I…'

Hiromi couldn't think. She knew it was wrong to be doing this but all it did was make a dark thrill shoot up her spine. She pulled away from Nagisa's lips, finding his dazed, panting expression adorable. "Go on, Nagisa. You can touch me however you like."

Irina took hold of Nagisa's free hand and brought it to her own barely-concealed chest. "That's right, Nagisa…get a good feel of us…" Her lips neared his ear and her sultry voice purred, making him shiver. "You look all hot and bothered. Let's get you comfortable."

Hands grabbed Nagisa's shirt and started to tug it over his head. The boy raised his arms and let his teacher remove his shirt, revealing his thin naked top half. 'Gotta admit. I can see why the girls all questioned if he was a girl with how thin and feminine he is. Especially if his mom has by keeping him feminized for a long while…'

Still, Irina's eyes stared at the bulge in his pants and she couldn't help but feel her curiosity spike. "Here, stand up and let's take off your pants."

Awkwardly, Nagisa got up and let the blonde unbutton his pants, tugging them and his underwear down to his ankles. When Nagisa's manhood was revealed to the two busty women, they stared at the teenager with shock written all over their faces when they got a good look at his lower half. Hiromi's eyes almost popped out of her head as she took in the sight of her naked son. 'How…how have I not known he had that before now?!' In her efforts to feminize Nagisa in order to live through him, she naturally assumed that his genitals would match his tiny size.

Irina had always assumed that Nagisa's loins would match the rest of him and that part of his insecurities were about how small he was down there. Instead, her jaw hung low as she stared at the enormous porn star-sized cock that rested between his legs. '…Well…I…uh…guess that's where all his testosterone went when he hit puberty.' "Wow…just…fucking wow…" She didn't have a ruler on hand but Nagisa was bigger than any of the men she'd been with on her assignments and she'd been with some pretty hung men. The boy had to be ten inches long with girth aplenty. 'Is it me or does his tiny frame make it look bigger.'

Nagisa's cheeks turned a brighter shade of pink as the women stared at his cock. Until recently, he'd always been ashamed of having such a big dick, doing his best to hide it from everyone. But now it was impossible to hide it from the staring women.

"Don't be so nervous, Nagisa. You should be proud. You're going to make a girl very happy one day. But tonight, the happy girls are going to be us."

Dropping to her knees, the lingerie-clad Irina settled herself between Nagisa's legs. Her womanhood was already starting to get wet just looking at the man's cock. The teenager gasped when her hand, soft as silk, wrapped around his meaty clamhammer.

"I…oh…" Nagisa's breath was taken away again as that soft hand started to stroke him, his body heating up in response. Instinctively he wrapped an arm around his mother's curvy waist and pulled her close, his head cushioned by her soft boobs. 'Is…is this really happening?' he thought, marveling at the softness of Hiromi's boobs while she held him gently.

Hiromi knew what Nagisa wanted when he turned his head to put his lips to her clothed titties and let her son have what he wanted. She pulled the thin bands of fabric concealing her nipples down, exposing her hard, pink nubs to her son. Reaching up, Nagisa cupped Hiromi's breast as his lips found her nipple, suckling her gently. "Nghhh…" Hiromi bit down on her bottom lip, heat starting to flourish in her loins. Despite how thread-bare her lingerie was, she felt like she was burning up as she let her son do as he pleased. A shiver ran down her back when Nagisa's free hand slipped downward to cup her soft ass.

Irina was pleased to see Nagisa getting into it. 'Wow, he's so big I can barely wrap my hand around. How the hell was he keeping this hidden in those tight pants of his?' she wondered to herself. Noticing Nagisa suckling his mother's tits, Irina decided to show off her own skills with her breasts. "I pegged you for a boob lover. I bet you love breasts as much as that octopus," she said teasingly, cupping her ample chest.

"Mmmmh!" Nagisa's blue eyes went wide when he felt his cock become enveloped by two huge, soft titties. He pulled away from his mother's tit to let out a soft groan while his teacher gave him a paizuri. "M-Miss Jelavic…that feels…amazing…" he panted before his mother captured his lips in another kiss.

Smiling at Nagisa's cute reaction, the horny blonde squeezed her tits around the huge cock poking out of her fleshy prison, earning another cute groan from the boy. Leaning down, the seductress stuck out her tongue and gave the thick tip a long lick, like she was licking a scoop of ice cream. "Mmmmh…" Her purring made Nagisa and his mother blush as she licked his cock while squeezing her tits against his long shaft.

Nagisa's head was spinning while he remained tongue-tied with Hiromi. His hand let go of her ass to reach up and run his fingers through her soft hair. Hiromi took his free hand and squeezed it gently, knowing her son was about to blow his load from the way he was moaning into her mouth.

"Mmmmmh!" Nagisa arched his back, thrusting his hips up into Irina's titties as the head she was licking started to pulse right before a geyser of white cum erupted from his slit, filling her opened mouth. "Nghhh!"

"Ahhh…" Irina hummed with full lewdness, sticking out her tongue farther to catch more of Nagisa's seed. She wrapped her lips around his head and gladly took the remainder of his load into her mouth, her panties soaked just from sucking him off. She hadn't gotten laid since she'd came to kill Korosensei and having such a big cock at her fingertips was really getting her turned on.

Pulling her tits away from Nagisa's manhood, Irina swallowed his treat, nipples aching with need as she watched Nagisa go back to sucking on his mother's tits. When she looked back down, however, Irina was taken aback by the fact that Nagisa was still hard as a rock. "Well now, guess you've got more stamina than what we figured." Standing up, the buxom blonde turned Hiromi's head away from her son and captured her lips in a deep, sloppy kiss, sharing the taste of Nagisa's cum still on her tongue.

Hiromi had never been with a woman before, let alone kiss one. But she melted into Irina's sensual kiss, the woman's hands running over her body, making her skin feel like it was on fire with her soft, sensual touch. "Mmmh!"

Nagisa stared lustfully at his teacher and his mother while they made out, gently stroking his slickened shaft while watching them. Irina broke the kiss and gently place her hand on her student's thin chest and gently pushed him down onto his back, letting him scoot towards the middle of the bed. "Guess it's time we give this big boy some real tender love and care…"

Slipping off the bed, Irina peeled her wet underwear down her legs and unclipped her bra, baring it all before the pair. Hiromi felt even more self-conscious staring at the woman in the buff. 'She acts more like a woman hooking up with a sugar daddy. What kind of teacher is this lewd woman?'

Getting back on the bed, Irina straddled her student's lap, lifting her hips. She licked her lips when she felt the tip of the boy's cock brush against her pink, wet entrance. Nagisa surprised her with his initiative, putting his hands on her thin waist and pulling her down onto him. "Oh!" Irina's breath hitched as that thick head pushed past her folds, diving deep into her honeypot. A groan left her lips, her back arching from feeling her womanhood get stretched by his cock. "Oh fuck!"

Having lost his virginity to his sexy blonde teacher, Nagisa almost went cross-eyed from the feel of a woman's walls gripping his cock. Nothing could prepare him for the tight, wet warmth of a woman's honeypot. "This…this feels…" Nagisa squeezed his eyes shut and reveled in the ecstasy once Irina started to ride him, her huge breasts bouncing with every slide down his cock. "This feels amazing!"

"Ah! Ohhh!" Irina moved faster, her ass clapping with the thin boy's hips. Her body surged with pleasure every time Nagisa rubbed against her G-spot. Seeing the boy's cute expression, she rolled her hips, groaning while feeling him shift around her. "Ahhhhh…"

Nagisa's eyes looked over at his mother. Something stirred within Hiromi as she looked at her son's expression and she felt the urge to be a part of this too. Smiling down at him, the dark-haired woman scooted around Nagisa until her knees rested on either side of his head. "Here, Nagisa…lick me here…" She reached down and moved her white panties out of the way, revealing her moist honeypot to her son's face.

Ever since Nagisa had started to become aware of his sexual urges, the thought of fucking his mother was a thought he knew he should never indulge in but did anyway. To have his beautiful mother sit on his face and beg for him to eat her out was almost enough to make the boy blow his load. His hands left Irina's hips and went to Hiromi's soft ass, finding her cheeks softer than he imagined. As soon as his mother lowered herself onto his face, his tongue found her honeypot. Hiromi's gasp made Irina chuckle, it having been years since anyone has gone down on her. "Oh! Oh my! I…nghhh!" Hiromi's head started spinning as she felt that small tongue touch her sensitive lips.

Hiromi put a hand over her mouth to stifle her moans. However, the naked blonde bouncing on her son's cock would have none of it. "Hey now, let Nagisa hear those moans." Her hips bouncing wildly, Irina grabbed Hiromi's hand and pulled it away from her mouth. "He needs to know if he's doing a good job. If you want to do something with your mouth…" Leaning forward, Irina surprised Hiromi by cupping her breasts, squeezing them through her bra. And unlike the inexperienced Nagisa, Irina knew just how to handle a woman to make her moan. "My lips are more than available."

The hands groping her titties and tongue diving into her pussy made Hiromi's head spin. Her body felt like it was on fire with pleasure. It didn't matter how wrong it was anymore, Hiromi had given in to the feelings within her. She wrapped her arms around Irina's shoulders and leaned forward, giving the blonde's luscious lips a good kiss. "Mmmmmh!"

Beneath her, Nagisa was busy eating out his own mother. His hands played with her soft ass, groping her plump cheeks as his tongue explored Hiromi's depths. The taste of a woman was strange to Nagisa but he ignored it when he heard his mother moaning above him, listening to her make out with Irina. All the while he felt the blonde assassin ride him like a cowgirl, her experienced walls gripping him ever more tightly. "Mmmmh!" He could feel his tip press against something every time Irina reached his base and knew he'd bottomed out her pussy. Those tight walls kept choking his manmeat, earning more groans from him that were muffled by Hiromi's pussy.

"Mmmmh!" Pulling away from the mother's lips, Irina groped her own chest and began to bounce faster. The bed shook and creaked from the intensity of her riding. "Yes! Ohhh! Oh god! Nagisa! You're a fucking breeding stud!" she slurred. Having pined after Karasuma for so long, Irina had forgotten how good it felt just to have a big and hard cock in her pussy. 'Dammit! I don't want to give the brat the satisfaction of making me cum but…' As much as she tried to deny it, Nagisa was going to make her cum. "Ah! Oh god! Ohh…" Her face twisted with absolute pleasure as she orgasmed, her pussy clenching around Nagisa's shaft, coating his lap and balls with her juices. "Ahhhh…"

The tightness was too much for Nagisa to bear. Thrusting up into that hot honeypot as hard as he could, the would-be assassin grunted before the pressure in his loins reached its limit.

"Mmmmmh…" Irina licked her lips when she felt a wet heat fill up her pussy. Ever the prepared seductress, she was already on the pill to prevent any pregnancies so she could enjoy Nagisa's creampie to the fullest.

The two women promptly got off of Nagisa, Hiromi's lower half tingling with the need for his tongue to return to it. As Nagisa sat up, the women were shocked yet again to find that the boy was still hard. When her son turned his head to face her, Hiromi blushed from the heated look in his eyes. She and Irina had flipped his switch completely.

"Mom…" Nagisa reached out and pulled his mother into a breathtaking kiss, surprising her with his sudden domineering attitude. "I want…to fuck you…" he said as he broke the kiss.

"Yes…" Breathing hard and preparing herself, Hiromi turned around and got on all fours, sticking her ass out in front of Nagisa. "Go ahead, Nagisa. I'll take all your lust…"

Nagisa's heart beat so hard in his chest it was amazing nobody else heard it. He peeled his mother's white panties off her ass and slid them past her ankles before he mounted the woman. Ever the temptress, Irina slid behind Nagisa and pressed those glorious breasts of hers into his back. "That's it, Nagisa…put it…" Her hand took hold of Nagisa's slick cock and guided it towards his mother's hole. "Right here."

Gripping Hiromi's waist, Nagisa found his nerve and slammed home. "Ah! Oh fuck!" gasped Hiromi, her womanhood completely filled. 'Oh fuck he's bigger than his father! This…is so wrong but…' Her thoughts melted away though, her mouth spewing moan after moan as Nagisa pounded her from behind. Her soft, bubbly ass rippled like jello with each smack of her son's hips. "N-Nagisa! Ohh!" Her breasts swayed beneath her, Hiromi's fingers gripping the sheets. Still pressing her body against her student's, Irina smiled at the way Nagisa was dominating his mother. This had gone better than she had hoped. "Yeah, that's it…fuck her hard," she whispered into his ear. Nagisa turned his head to capture her lips in another deep kiss, shivering as she ran her hands all along his thin chest.

Building confidence with every smack of his hips, Nagisa gave his mother's ass a hard smack. "Who is bigger? Me? Or Dad?"

"Y-You are!" Hiromi shouted, unable to keep herself from bucking into Nagisa's thrusts. Her son was hitting every sensitive spot inside her. "Oh fuck! Don't stop!" She felt like her pussy was melting, arching her back while moaning for more. Her ass stung with each smack to it, leaving a bright red handprint on her soft cheek every time Nagisa struck it. As wrong as it was, she couldn't help but love this. "Yes! Fuck me! Fuck me, Nagisa!"

Turning his head to kiss Irina again, Nagisa quickened his pace. The bed banged against the walls and creaked constantly but it was ignored by the horny trio. Irina continued to fan the flame of lust inside of Nagisa, her hard nipples digging into his back as she kept grinding her body in time with Nagisa's thrusts. Her hand reached down between his legs to cup his swaying balls. "Ah! Miss Jelavic!" Nagisa gasped when his teacher gave his tender sac a gentle squeeze.

"Are you about to cum, Nagisa?" Irina could tell he was close from how his thrusts were becoming frantic.

"Y-yes!"

"Go on. Cum inside her. She want you to creampie her…"

"Yes!" Hiromi shouted, bucking into Nagisa's hips as hard as she could. "Cum inside me!" Irina had given her birth control pills so she didn't have to worry about their incest resulting in a forbidden child. "I'm cumming! N-Nagisa!" Her eyes rolled into the back of her head and her pussy tightened around him, staining the bed with her juices.

"M-mom!" Nagisa felt that familiar pressure shoot through him. His head was turned by Irina again, who swallowed his moan while he came inside his mother, pumping her womb full of cum. "Mmmmh!"

Silence filled the room. Hiromi sat up once her son pulled out and the two women hugged the small teen, his head cushioned by their huge breasts. "So, Nagisa…did you get all of your pent-up lust out of your system?" Hiromi asked, gently patting her son's head.

Nagisa opened his mouth to speak but Irina beat him to it. "Well considering what's poking me in the stomach, I think that he's got some gas left in the tank. So, shall we continue?"

Blushing, the student/assassin looked up at the two busty women and spoke his mind. "Actually, can we take this somewhere else?"

His mother blinked in confusion. "Somewhere else? You mean like your room or the couch?"

"…No…"

An hour later…

This time both women had to fight to keep their moans from behind heard as they gripped the balcony's railing. Nagisa grunted while fucking Irina from behind, thrusting his fingers into his mother's pussy. The women found to their astonishment that Nagisa had the endurance and stamina of a breeding bull, fucking them one after the other.

"Nghhhh!" Nagisa threw his head back, the stars above him spinning while he filled his teacher's pussy to the brim. Beside him, Hiromi gave a muffled moan as she squirted around her son's fingers, praying that none of her neighbors looked out the window. Her son's request to fuck outside was ludicrous but she just couldn't say no.

Panting and sweating hard, Nagisa pulled his hand and cock out of the women and knelt to the ground, exhaustion finally kicking in. "That…was…amazing…"

The women joined him on the floor of the balcony, hugging the teen. Feeling her son's cum inside her, Hiromi made a decision. "Nagisa…if you ever want to unload any pent-up lust, we can do this again whenever you want."

The statement shocked Nagisa, who thought this was just a one-night only deal. "Really?"

"Yes."

Irina hugged Nagisa tighter. "That goes double for me. There's no way I'm turning down this cock. Who knows? I can probably get you work as a porn star."

Hiromi raised an eyebrow at the naked blonde. "The hell kind of teacher are you?"

"One that likes your son's cock, that's for sure."

Nagisa smiled and hugged the mature women before they carried him back inside to snuggle in his bed, glad that he finally had an outlet for his love of mature women.

'Note to self though: change my damn password…'
