Hey, guys! [girlfriendoftheauthor] here. Before reading this, let me warn you that my boyfriend, Big Diesel, has nothing to do with writing this story. If crossdressing, cosplay, reverse rape, and snowballing isn't your thing, then please refrain from reading this story.

This story is the follow-up to "Manic Mother." Izuku's mother and girlfriend are away. However, a surprising guest comes to visit and it is definitely not for the better.

A weekend with his Katsuki-like, tsundere-yandere cousin, Izumi Midoriya!

The sound of video games filled the room as Izuku was enjoying his Friday evening playing on his PlayStation console. Overwatch was his game of choice. It was a gift from his mother for his efforts of being a good son as well as a wonderful lover. He was fortunate that he had the house to himself. Wherever his family was didn't matter for now as he was taking advantage of his alone time. He was getting ready to enjoy his afternoon until he received a phone call. He sighed, putting the game on pause to see who was the person calling.

It was his mother. Izuku put down the joystick as he answered his mother's call. "Hello, mother."

"Hello, lover boy," she purred to her son. "Letting you know that I will be out of town taking care of obligatory duties with my pesky husband." She sighed through the phone. "It makes me pout to see you alone without me." She took another breath. "Is our lovely pet okay?"

"If you are saying Ochako, then yes ma'am. She is back at home for the week," said Izuku. "She has to go to the doctor. Also, the pet shop has her diamond studded collar ready."

His mother became joyous. "So, excited. Can't wait when she sports it in the bedroom. I will be pleased as punch." She made a slight chuckle. "Anyway, I wanted to let you know that my sister is going to be in town this weekend."

"That's cool," said Izuku as he resumed playing his game while talking with his mother. "Whatever floats her boat."

"Yeah," said his mother. "She brought her daughter with her."

A ringing in his ear caused Izuku to nearly drop his controller. "Say what?"

"My sister's daughter is in town for the weekend too," said his mother. "Since I knew you would be home, I want you to keep her company for the time being until they leave on Sunday."

Izuku dropped the controller. "Mom, do you know what you have done, right?"

She sighed heavily. "Sorry, sweetie. I can't turn down family." She took a breath. "However, let me know if your cousin tries to pull any stunts on you please, baby? I don't know how much thicker blood can be if she tries okay, baby."

"Yes, ma'am."

"I am at the hotel. I will close my eyes and think of you. And only you." She made kissing noises. "Be good for me, sweetie. And please, let me know if Izumi has any ideas." She hung up the phone.

Izumi Midoriya was Izuku's cousin. Nicknamed Izuku's twin, she and Izuku were attached to the hip growing up. Inko's sister married his father's brother and thus Izumi came to the world. Although a few months apart, Izumi admired her cousin.

Or at least she did at some point.

Why are you sharing my space, you baka?! Can you go somewhere that doesn't require you to exist?

Why are you getting on my nerves? Can you get it through your thick skull to get away from me?

You better shut up and take your licks, Deku! I can see why Kacchan always thought you were a damn bitch!

I am your queen, Izuku! Bow down to me!

At least Katsuki had some mercy, Izuku thought, thus secretly nicknaming her Hockey Temper.

The phone rung. A picture of his cousin popped on the screen. Interesting how this soft-faced feminine version of himself was the devil's daughter.

"Izumi," he said aloud. He stared at the phone for a moment. Was he really going to allow this Hockey Temper his time on this beautiful Saturday? He let the phone ring until it went silent. He sighed happily, returning back to the game at hand. He unpaused the game, continuing to play with full concentration.

The phone rang again. He saw that it was Izumi again. He groaned on why was she calling him again. Regardless of what his mother said, he wasn't going to invite her over. This time, he declined her call. He then returned back to the game.

The same time he unpaused the game, he heard something hitting the window. He turned to see the source of the noise. His mouth was agape when seeing what he had feared. The Queen Hockey Temper perched a ladder in front of his window. She displayed a Cheshire Cat grin, waving delicately with her fingers. What surprised Izuku was that she wasn't wearing her typical clothing.

On a regular day, Izumi always wore the latest fashion trends. A day never went by without her wearing anything name brand. However, today was different. She was wearing an outfit that he had easily recognized. She was wearing a costume that looked similar to the character, Astolfo, or Rider of Black, in the Fate/Grand Order series. Her pink wig was flowing in the wind. She was swaying her hips and throwing peace signs. Surprisingly, she was in a happy mood. Izuku was careful when seeing her smiling. Despite the bewitching look she was displaying, he knew that she was in an annoyed mood.

One thing he should have learned throughout his relationship with her: never ignore her phone calls. As she made her way to the window, he saved the game. Before he turned off the console, the Queen Hockey Temper was opening his window.

She tsked as she climbed through his window, landing on his bed. "And to think you let this princess of royalty to use such a subservient entrance." She dusted herself off. "If I didn't know any better. You were trying me to teach me a lesson." She stuck her tongue. "I hope this dog isn't trying to sit beside himself."

He scratched under his arms. "No, Izumi. I wouldn't do anything like that."

"Izumi," she questioned her cousin.

"No, mistress," the emerald-haired child murmured. He stayed at the floor, knowing that he was now in the position of his role whenever she was around. "I wasn't trying to sit beside myself."

"Good! Just remember your place and we can get along famously," she said.

"Yeah, yeah," he said under his breath. "So, what reason are you here today?"

She placed her hands on her hips. "How rude of you when talking with a guest? Why can't I come and have a chat with my property? I do give my servants plenty of love you know?" She produced her smile. "Plus, I am visiting and like auntie said, you must serve me each and every way."

While he was thinking of a way to get himself comfortable, he couldn't but to observe the outfit she was currently wearing. Her pink wig complimented her porcelain skin. Her stockings were riding to her creamy thighs. He blushed when he saw a bit of her white and blue striped panties. It didn't go unnoticed from Izumi as she blushed in the process. She closed her legs.

"Hey, you pervert," interjected Izumi. "My eyes are up here."

He looked away. "Sorry, Mistress Izumi." He focused his attention back to the matter at hand. "Out of curiosity, the reason why you are wearing this?"

She giggled. "Well, yes!" She crossed her legs. "I am thinking of going to the cosplay convention they are having in town this weekend. And well, since I am the most beautiful goddess of this region, I think I should make my presence there with the other nerds." She swayed her hip, rubbing her butt on his bed. "Give many perverts like you wet dreams."

"That's great," mentioned Izuku as he stood up. "So, is that the only reason you came?"

She gave him a soft karate chop to the head. "Clothy cloth ears, don't you ever listen, you dog?" She rubbed the back of her head. "I can see why Kacchan makes fun of you. Remember what auntie told you, you are to serve me each and every way. She blew into her hair. "I thought you should be grateful someone gives a damn about you." She paused for a moment, standing up. "And there is something I want you to try on."

"Try on," he retorted.

"Yes," she said as she peered closer to his face. "Yes, try on. Do you think I was going to the convention by myself? You must have been fooled." She went to the window where she pulled a black plastic bag inside of the room. "Since you are used to throwaways, I would be damned to use any of my name brand suitcases." She giggled. "I thought this costume would suit you for the convention." She wavered her hand to the closet. "Now, go inside and give this a try for me. I think it might suit you," she winked. "Come now, chop chop. Get dressed, you dog."

"Sure, jackass," he mumbled to himself before getting his arm grabbed by Izumi.

"What was that, you dog," she asked. Izuku noticed the twitching vein on her forehead as she remained smiling. It briefly reminded him of those moments in anime before he was going to get hit. Her smile and her furrowed eyebrows matched the occasion.

"Nothing," he said with a nervous smile.

"Good," she said before hitting him on the shoulder.

Ouch!

Izumi watched Izuku entered the closet. She licked her lips when seeing his butt. Her eyes enjoyed the privilege of seeing Izuku's rear end. She lied back on his bed, grabbing his pillow. She sank her face into his pillow, inhaling his scent.

"Oh, my God. Why must you tempt me," she said to herself. "It is like you are asking me to rape you." She scoffed. "Stupid Icchan." She grabbed the pillow and turned over on top of it. She started to feel the itch from her groin. She felt that she was getting wet. She was quite fortunate to be wearing a pad today.

"If you honestly knew my opinion of you, stupid Icchan," she moaned to herself. "If you knew how much I care about you. If you knew how much I don't want those bitches around you." She pressed her body on his pillow, humping while sniffing his covers. "Stupid Icchan. Stupid bitches for wanting him. I will mark him. I will make sure he would never forget the name, the aura, the scent of Izumi Midoriya." She paused for she forgot that Izuku was in the closet. The outfit that she had for him to wear was something special from her collection. It was one of the many secrets that the Hockey Temper kept to herself.

How can she tell the others that she was a closeted otaku? The images of her drawings, the works of her fanfiction were based only Izuku. She kept her composure when she saw the door partially opened.

"Izumi," said Izuku.

"Yes, peasant," replied Izumi.

"Are you sure that it is the right outfit?"

"Why yes! I got it just for you?"

"How can I say this. It is very girly."

She scoffed. "Do we have problems? Do I need to pull out the collar?"

"No. No, you don't."

"Good! Now step out and let me see."

Izuku stepped out of the closet. He displayed nervousness, especially when he came out wearing a costume that was designed for her girl. He was sporting a pink wig with bows in his hair. His outfit resembled the character, Madoka, from the Madoka Majica series. He stood nervously, flustered and blushing at the sight before him.

Izumi crossed her legs, smiling at the sight before her. "Now don't you look beautiful, Izuku." She coughed. "I mean Madoka!"

He looked to the floor. If he would have known that this was going to happen, he should have made that offer to hang out with Ochako at her place. "This is totally weird." He covered his mouth. "Oh, God. Did I say her catchphrase!"

He saw Izumi displaying her cell phone. The sounds of clicking made him realize she was taking pictures. "This is rich. Look at you being a classic trap." Izumi stood up and walked to Izuku. She observed his features. "Not bad, not bad. Mommy did a great job designing your outfit to your size."

"You mean you were planning this," questioned Izuku.

"I did," she said smiling. "Guilty, my subservient peasant. Much, much guilty." She took a phone to take a few more pictures of Izuku. "Do a couple of poses. I couldn't imagine what others may think if they caught you in this position."

He covered his face. "Please, Izumi. Please, I don't want that to happen."

She shook her head in disagreement. "No, this is rich! I am definitely holding on to these."

Izuku tried reaching her phone, but it was out of reach. "Please, Izumi. Don't do it." Izumi was running around in his room. Izuku was trying to get to Izumi, but she had the upper hand.

"Stop it!"

"I don't wanna!"

"Please, Izumi!"

"Hell no, you dog!"

"You are pissing me off!"

"Then make me stop, Madoka!"

Frustrated, Izuku grabbed his cousin by her hips. He pushed her to his bed. Izumi was surprised by his instant dominance. He was now on top of her. His hands were on both of her arms. She still kept the grip on her cell phone.

"Now, give me the phone," demanded Izuku.

She kept her composure. "And if I say no? At this point, if people were to walk in. Who would be in trouble? Me or you?"

He was irritated. As much as he wanted to argue, to rant, there was no use. It was true. He cursed under his breath.

She smirked. "Yeah, yeah. Quiet and docile. I like that. Very good!" As he lessened his grip, she grabbed his wrist, throwing him to the other side. She smiled as she was having the upper hand and she was on top of him.

"Icchan, Icchan, Icchan," she tsked. "Despite my girlish charm, I am quite dominant in any way." She winked, blowing into his ear. "You might as well accept your defeat. For you can never beat me."

He groaned. He looked away from the embarrassment he was currently facing. Here he was confined under Izumi and wearing girls' clothing. Not a way that he had his day planned.

"You know, Icchan. You are very cute when you get frustrated." She used her free hand to caress his chin. She pressed forward and kissed his chin. "I like how you think you can run me, but accept the fact that I will always be the victor."

"Fine," he said while he was blushing. "Do what you want."

His emerald-haired cousin gave him a smirk. "With pleasure, I-zu-ku!" Izumi pressed forward and kissed him on his lips. He entered his tongue inside of her cavern. Izuku was surprised but became too entranced of the moment. He closed her eyes, loosening his grip as Izumi wrapped her arms around him. They broke the kiss, leaving a trail of saliva between the pair.

"What the hell," said Izuku before she put her finger to his lips.

"Shh!" exclaimed Izumi. "Don't know why you should be shocked. This is what you asked." She kissed him on his neck. As she applied her tongue to his neck, he started moaning under his breath.

"Izumi," he moaned in between breaths. "Stop! Stop it, I said. Please!"

His cousin didn't listen. She continued licking his neck, trailing it to the collarbone. She used her hands to open the collar of his shirt. She began unfastening it. "I must say, you dog. You are very sexy dressing like Madoka. A sexy trap you are, Icchan."

Izumi was unfazed with her actions. She planned from the beginning. From convincing her mother to come to the town. Forcing her father to establish a visit with his brother and making Izuku's mother come to visit him. She planned it. Izumi wasn't stupid. She could smell the bitch motherly scent on him as she used her saliva to mark her territory, removing any scent of her bitch auntie.

She continued removing every article of clothing that was on Izuku. The only thing she left behind him was his pair of panties. "Sorry for undressing you, Madako. I mean, my humble servant. I didn't want to dirty your clothes." After taking off his clothes, she removed her clothing as well. What surprised her was seeing Izuku in this position.

Defenseless demeanor. Tear-stained face. You are mine, Izuku! YOU ARE MINE! TIME TO MAKE MY CLAIM ON YOU!

Izumi rubbed her fingers through her wig before returning to her cousin. Izuku's breath was labored as she continued to lick his chest. He moaned as he felt her tongue licking him. He tried to resist but felt weakened by her charms.

"Mistress, please don't," he moaned to his emerald-haired counterpart. Izumi nibbled on his nipple, savoring each moment. She continued until she had enough of one and went for the other.

She continued down his chest, licking him down to his navel. He pressed his tongue around the navel, circling it. He grabbed the sheets tightly as he felt his erection protruding from his panties. Izumi kissed down his navel until she reached his groin.

"Your clit is getting messy," she purred to Izuku. "Were you expecting this, Madoka?"

Izuku's breath wavering as he already knew what his cousin was going to do.

"Do you want me to play with your clitty," asked Izumi with a devilish grin.

Izuku didn't respond. He was turning beet red. It made Izumi smile. "You not responding doesn't help you." She hovered her breath over his dick. He let out a slight moan. "What do you want me to do, Madoka?"

He muttered. "Please...please….please explore my clitty, Astolfo." Sorry, Mom! Forgive me, Ochako!

Izumi grinned. "Wise choice. Allow me to partake on this, Madoka." I got him! Yes! He surrenders! You hear that, you interlopers! He belongs to me! He is mine! MINE!

Izumi opened his mouth to allow his dick to enter her mouth. It tasted funny at first but continued to lick his throbbing member. Izuku took sharp breaths as he was feeling the pleasure from his dick. "More, Astolfo. More, please."

She licked the tip of his phallus with her tongue, tasting the precum that was coming from his dick. She was a novice when sucking on a penis. But, it was weird that how long his girth is when it was in her mouth. She pulled out when she could no longer handle it.

"I must say, Madoka, your clit does taste good," answered Izumi as she came back to his dick. She licked the shaft, gripping to his testicles massaging them. He moaned the moment she did that.

"Astolfo, Mistress. This feels good. Oh, my God. I am going to cum. I am going to cum," he moaned.

Izumi returned her mouth to his dick and continued to lick it. "Come inside here. I will take it all."

"I am coming," he screamed as he pressed her head forward. He released her sperm into her mouth. At each spurt, Izumi continued swallowing his sperm. Izuku was panting hard. He couldn't believe the events that were unfolding in front of him. Izumi came on top of him, opening her mouth. He opened his mouth as the trail of his sperm entered her mouth. She came forward and gave him another kiss, swapping each other's content.

Izumi broke the kiss. Izuku looked away while blushing.

"Was that pleasing to you, Madoka," questioned Izumi as she swayed her hair.

Two hours later….

Izumi was sitting on the couch wearing her regular attire - a white buttoned-down blouse with a plaid skirt. She was reading one of Izuku's manga as she was waiting on her cousin.

"Hurry up, Icchan," she said to Izuku. "We don't want to be late for the movie."

"I am coming. I am coming," said Izuku.

"Be grateful I am a good mood to not call you names, but you are making it harder on me," said Izumi.

Izuku stepped out of his bedroom. He was nervous as he was wearing a diamond-studded collar. "Do I really have to wear this?"

She gave him a thumbs up and trying not to get a nosebleed. "With me, you do. To let the others know that you belong to me, baby."

"Izumi, we are cousins."

"Izumi?"

He sighed. "Izzy."

She smiled as she hit him on the shoulder. "It beats calling me mistress, doesn't it?" She slapped his ass. "C'mon, you dog! Let's go. You can buy me popcorn." She took his hand. "Oh, yeah. We need to be back in time for the cosplay convention tomorrow."

"You were serious?"

"I wouldn't come all of the way here for nothing. Especially when my Icchan is alone," she told him. "Now, let's go!"

Izuku grabbed his keys and turned out the lights. He took his cousin's hand as they exited out of the home.

Well, it could be worse! At least my mother didn't see this, I hope!

To be continued….

Himiko Toga sat quietly on the roof of Izuku's house as she feasted on an owl. It was a meal she didn't care for, but she needed sustenance. For the last few days, she had to live on rodents, canines, felines, and the occasional drifter before finding Izuku. She had to keep a discreet appearance. She did not want anyone to know that the presence of vampires still existed in this region.

She smelled the night air. It tasted of Izuku. Ever since the first encounter she had of him, she could never get enough of his taste. It was quite unfortunate that he doesn't recall the incident, thought the sadistic vampire blonde.

In the past, she had numerous of people who she had for her meals. Her preference was males. She had the occasional female if there weren't males available. But to Izuku, he was special.

I can smell the stench of that bitch's blood. I wouldn't feed it to worst of vermin in this wretched earth. The worms have a higher dynasty than that harlot.

Her yellowish-eyes darted to Izuku and the bitch Izumi as they made their way to the bus station. Himiko gave herself a smile as she waited for the day to release her vampire quirk onto Izuku Midoriya.

But not today….

I am coming for you, my dearest Izuku. It is because when you are there, I want to break you down from limb to limb. I want to tear your limbs as you scream out my name as I moan into the pleasure. Oh, Deku. How much I love you. How much I want to kill you. How much I want to love you. Such a beautiful noise you make after seeing you bleed, after tearing out one of your ribs. Oh, Deku. How you pull my heartstrings. How much I want to see what your insides look like. You make me excited, Deku. And that makes you second to my favorite thing...blood!

Are we witnessing the first vampire quirk? Izuku, you have a lot on your hands. Your mother, Ochako, your cousin, and now Himiko? Let us pray for you, Izuku. Until next time!

To be continued...for real this time!
