Chapter Text
Mitsuki sat in her living room, reading a magazine, her fingers drummed annoyed against the cover. She huffed when she read the pointless news article. What a shit-ton of bullshit!
She briefly looked up when the door opened, and her teenage son came home from school. “Hello, Katsuki,” she greeted, but she got nothing more than a grunt in return. Katsuki stomped upstairs, and she heard his bedroom door banging. This damn brat!
Sighing, she got up and put the magazine down. Mitsuki walked to the kitchen to prepare lunch. She didn’t really feel like cooking today, but if not, she would get an earful from her annoying brat.
After an hour, she was done with the preparations, and it only needed to cook in the oven. Since it was merely twenty more minutes, she decided to get her son. Hoping he was in a better mood now, she was already underlying aggressive herself. If he rubbed her the wrong way, she would surely explode, now that her useless ex-husband wasn’t around anymore to stop them.
She marched over to his door, and without knocking, she entered. “Katsuki! Lunch is ready in …! Woah!” She huffed when she saw Katsuki’s shocked expression.
“You damn old hag! Why can’t you knock?!” He squeaked while he tried to cover himself with a pillow. “You take away my room key, so at least have the decency to knock!” He was completely red-faced.
Mitsuki huffed; she mustered her son. For a brief moment, she was uncomfortable, walking in on her son masturbating. “Don’t talk to me like that!” She fired back, and instead of walking out, she stepped into the room.
She had seen his dick when he was a child, of course, but not since he entered puberty. He was bigger than she expected. It was also the first dick she had seen in ages. From the brief glimpse she had caught, it looked thick and dark.
“The fuck are you staring at me? Get lost!” He tried to shoo her away, but to his horror, she came closer. Eventually, she sat down next to him on the bed. Katsuki crawled as far away from her as possible, still covering his cock with the pillow. “Oi, are you deaf?”
“I can hear you just fine. As I said, don’t talk to me like that! I’m your mother!” She scolded him once again. Her ruby eyes looked into his crimson ones.
“Yeah, exactly, so get lost. I don’t want you seeing my dick!” Katsuki couldn’t believe that this was happening right now.
“Have you done it a lot?” She asked. His eyes widened, and his cheeks fired up even more.
“What the hell? Old hag, that’s none of your business!” He stared at her as if she had lost all of her screws now.
Mitsuki came closer to him, crawling onto the bed. “I could give you some tips for your future girlfriend.” She changed her voice slightly to sound more appealing and cutesy.
“Huh?!” This sentence completely fried Katsuki’s brain for a few seconds. What was she talking about? Give some tips? Future girlfriend? His shock was long enough for Mitsuki to pull the pillow out of his grasp. Revealing the thick, veiny cock of her son to her. It was still fully erected and pulsing.
Katsuki was frozen when the pillow blockade got pulled away, and his cock was now exposed to his mother. That was really the worst. “So beautiful,” he heard his mother say. It rang in his ears; it sounded so fucking wrong. The words he wanted to yell died in his throat when her fingers started to caress his phallus.
“Let mommy handle this little problem of yours. I will show you some tricks that will make you a pro in no time,” she huffed. Her fingers brushed over Katsuki’s glans, and the teenage boy winced.
He shook his head violently. “No! Y-You can’t! S-Stop it! Are you crazy?” He yelled, shocked when a moan slipped out of his mouth when her strokes got faster.
Her grip got harder, and she pumped him harder. Katsuki’s brain was still overloaded with the whole situation, and he couldn’t react to her doings. “You see that I can do it. Katsuki, I’m your mother. I had your dick in my hands when it was super tiny. So no need to fuss about it.” She looked up at him. Her eyes were crazy with lust. “I’ve seen it all before. Mommy knows what’s best for you. I can make you feel so good!”
“No! Stop! I don’t like it – aaaah!” He groaned out when her hot tongue licked over his meatus. Her hands still worked his length while her tongue and lips teased his tip. Tears shot into Katsuki’s eyes when the realization hit him like a truck. His own damn mother gave him a blowjob! His own mother put his dick in her mouth and thought it was normal!
She sucked on his dick and giggled when pre-cum started leaking out. Wet, lewd sounds came from her when she pushed her son’s cock deeper down her throat. She couldn’t believe it, but his girth was already so wide!
With her hands, she held Katsuki’s legs open, he desperately tried to get her off, but she sucked herself tight on his cock. It was such a close fit; he hit the end of her pharynx too.
“Stop! Stop! Stop!” he repeated, but it didn’t matter. She bobbed her head ferociously, deep-throating his cock like a champ. The moans drove Katsuki crazy and let his cock twitch in a twisted pleasure. “Mom! I’m gonna cum!” He gripped her hair and tried desperately to get her off his cock, but she went even deeper.
And then Katsuki came. He stiffened completely when he shot his load into his mom’s throat. He was absolutely mortified when it wouldn’t stop. He heard her moaning, and it made him so sick.
She stayed wrapped around his cock for some time. He could feel her swallowing. Finally, she let go of his dick and licked over her lips. “That was so good, Katsuki, baby. You taste so amazing!” She caressed his red, embarrassed cheeks. “Lunch is almost done. Come down when you’re dressed up.”
Wiping over her mouth, she stood up. “Ui, you made me so wet. My panties are soaking,” she commented before she left.
Still in shock, Katsuki pressed his hands in front of his mouth. This had to be a damn fever dream, right? This couldn’t just have happened. No way his mother sucked his dick empty. No fucking way …
Sobs escaped him when he realized that it really had happened. Shit, how did he get into this mess? He grabbed his flaccid dick and inspected it. It was still wet from her saliva. He groaned in disgust and got a tissue to wipe himself clean.
Tears spilled over; he felt so fucking sick. How could he ever look at her again? He didn’t want to do it. He shook so much. His mother was the first person to ever do that! The first person to blow him one. The first person who swallowed his cum! This was so humiliating! Why was his mother such a sick freak?
“KATSUKI! Come down!” She yelled and ripped him out of his thoughts. With robotic movements, he put his pants on and walked down. He still felt absolute dread when he thought of his mother.
“I made your favorite meal for being such a good boy,” she brushed through his hair, making him flinch.
“I … I’m not hungry,” he stammered.
“I cooked for you!” she got louder. “So you are going to fucking eat!” She was in his face. “Don’t you dare disrespect me! I’m your mother!”
Katsuki gritted his teeth and sat down. “Why did you suck my dick then? Mothers shouldn’t fucking do that!” He shot back at her.
“Because you clearly needed relief. Otherwise, you wouldn’t have touched yourself,” she sat next to him, “and don’t yell it out like that, or do you want others to hear that?” She tilted her head. “What will they think when they find out that you fucked your mother’s throat?”
“I didn’t!” He retorted. “You wanted to do that. I told you to stop!” He pushed her away from him.
“But you enjoyed it!” she huffed.
“No, I did not!” He shook his head violently. “I didn’t enjoy it!”
“But you came so plenty in my mouth! There’s no other way than that you enjoyed it. Why else would you climax so heavily?” She purred into his ear. “Now, let’s not talk about it anymore. Let’s eat.”
Still, with tears in his eyes, Katsuki forced the food down his throat. It tasted fucking awful. He didn’t enjoy it … his mother was lying. He could never enjoy it!
“Oh, and you better not tell anyone, for your own sake. How would your little friends react when they learn that you mouth-fucked your mother? They surely would make fun of you,” she huffed mockingly.
Katsuki stared at the plate, balling his fist under the table. She was right; he couldn’t tell them. They would only laugh at him.
Lunch dragged on and on, and he had to listen to his mother’s stupid voice. He loaded his dishes into the dishwasher and finally returned to his room. He shut the door but growled when he couldn’t lock it. After an incident when he was eight, where he almost burned his room down because he didn’t have his quirk under control, he wasn’t allowed to lock his door.
He crawled on top of his bed and curled into a ball. This was all so damn fucked up! Why did she do it? Why?
Mitsuki sat on her bed late at night; it was almost midnight. For the rest of the day, she had thought about her actions. Why did she suck her son? She knew it was wrong, but when she saw his fat, veiny cock she couldn’t hold back. It looked so delicious, she just had to take him! Her pussy throbbed at the thought of her son. How big he had gotten.
Her fingers fumbled under the fabric of her pajama pants, and she pushed three fingers in. She fucked herself on her fingers to the thought of her son’s mighty cock. But it wasn’t the same … She wasn’t able to come, just from her fingers alone.
She didn’t have a cock in so long! Her pussy was burning with desire. So what if it was her son’s cock? Dick was dick! If she used protection, then she couldn’t get pregnant. It could be like any other cock. Mitsuki got up and looked into her bedside table; she had one condom left …
Enthusiastically, she picked it up and walked to Katsuki’s room. She entered and saw him sleeping. He looked so beautiful in the dimly lit room. Only the light from the hallway shone in.
She pulled the blanket away, almost disappointed that he slept with pants on. It would have been so much easier if he slept naked. Sighing, she slipped out of her pajama pants and panties. She really needed to prep him; with that, she pulled his pants down.
She grabbed onto his penis with one hand and started pumping it again. This action, however, let Katsuki wake up.
“What are you doing again?” He tried to get away, but Mitsuki wrestled him down.
“Just stay still, Katsuki. I just need to feel it!” She said. “Mommy needs you to do her a favor! Her pussy is so raw!” She serenaded.
“No! Don’t! Stop it!” He thrashed around so much that it would be impossible for her to mount his monstrous cock. So she picked up her pajama pants and wrapped them around Katsuki’s wrist before she bound them to the head of the bed.
“Stay still, son. The sooner you comply, the faster it will be over!” She smacked him in the face after the bindings were tight.
“Fuck off! Go away, leave me alone!” Katsuki pleaded. He cursed when he couldn’t get out of his restraints.
“It’s okay, Katsuki. Mommy knows what’s best for you. Just follow my orders, and everything will be fine!” She leaned down again, stroking him hard with one hand while getting her pussy wetter with the other.
“NO, LEAVE ME ALONE!” He yelled out. Mitsuki clicked her tongue and grabbed her slip as well. As an improvised gag, she shoved it into his mouth to silence him. Muffled screams could still be heard.
Eventually, Katsuki was ready, and so was she. With a horrified look, he watched as she crawled onto the bed. She straddled his legs, still playing with his cock around her entrance.
Tears ran down his cheeks, and he tried to talk, but, of course, he couldn’t. Mitsuki let out pleasured moans when she slapped the cock against her red, engorged pussy. Her head fell back when it slipped in for a few millimeters. She rubbed it against her edges.
With a sigh, she lifted her body and grabbed the condom. Then, she pulled it over Katsuki’s mighty cock with a saddened expression. When she arrived at the base, her hand wandered further, massaging his balls for a while.
She got back to what she was doing before. She crouched over Katsuki’s phallus and slowly sunk down on it. The girth parted her pussy lips and stretched her walls. Fuck, he was so much bigger than expected, and he wasn’t even fully developed yet! She slid down his length until he was fully sheathed in. For a brief moment, she waited to get used to the feeling.
“Oh! That feels already so much better than your father!” She panted while slowly starting to bounce. She rolled her hips and pushed repeatedly down on her son’s cock.
Katsuki groaned. He hated it so much! He could feel the bitter taste of his mother’s juices on her panties in his mouth; it was disgusting! His wrists were bound together hard; it really fucking hurt!
And then there was the uncomfortable feeling of his mother’s body bouncing on top of his dick! Tears streamed down his cheeks, and snot ran out of his nose into the piece of fabric. All he could do was hope that she would stop soon!
Mitsuki felt so alive when the tip of Katsuki’s cock hit her walls; she loved it so much! The girth was exactly the right size! She rubbed her clit with one hand, still pounding down on her son’s member. She moaned loudly when she climaxed. She hadn’t done it in nearly five years.
She felt her son stiffen when he came to his orgasm as well; he panted heavily. She pulled her slip out of his mouth, making him cough. “You did so great, baby, making your mommy come. This was the best sex I had had in years,” she leaned down and wrapped her arms around his neck. She heard his whimpers.
Finally, she lifted her lower body, and his flaccid penis slipped out of her. Her hand wandered down, and she gripped the condom, pulling it off carefully. She placed some kisses on Katsuki’s wet cheeks. “You’re my good, good, boy. This will be our little secret.” She rolled down from him with one last kiss, putting her panties on again.
She bent over to open the improvised restrains; as soon as he was free, Katsuki shied away from her. He was crying and shaking. “Sleep well, baby.” Then, to rub more salt in the wound, she pressed another kiss on his forehead before leaving the room.
Katsuki stayed awake half the night, scared, disgusted, and confused as hell. Why was his mother like that? Why did she do this to him? Of course, he understood what she was doing, but he didn’t know why. His dick felt so heavy. The places she kissed burned like fire.
He activated his quirk against his forearm. The pain wasn’t much, but it brought his thoughts away from his mother.
Eventually, he ultimately passed out from exhaustion.
Mitsuki, on the other hand, slept very well. She felt like she was in heaven. She was so satisfied with her sexual encounter. She didn’t care what it might have done to her son. She enjoyed it, and he would do it as well. Even if he hated it now, he would grow to like it!
