Ladies and gentleman, a spinoff of "My NieR Nights," "Mitsuki For The Weekend." Enjoy!

Katsuki put her hands to muffle Izuku's moans to keep him quiet without alerting her mother. She strutted Izuku in his futon while he was sleeping. A surprise attack, but she was in the mood. She needed to give him reminders of her love and what it meant to date a yandere. Katsuki was in all smiles as she dominated his dick into her pussy.

Feeling the warmth on her hands turned her on. She continued to thrust her hips as much as she could as she wanted a midnight quickie.

"Don't fight it, Icchan," she purred. "Just give in and get nice and wet for me, baby." She kept looking at the door. The last thing she wanted to see was her mother walking in.

She removed her hands, replacing them with her lips. She forced her tongue inside of his mouth, cleaning anything within. She wanted more. His lips, his dick. She wanted everything of him. And there was nothing no bitch can do to stop it.

"Yes, fuck me. Fuck me," she whispered to the whimpering Izuku. He thrust with all of his might. Heart-shaped pupils appeared in Katsuki's hungry eyes as she claimed her Izuku once more. "Get wet for me, baby. Come inside me, now!"

Izuku whimpered in silence as he released all of his contents inside of Katsuki. She locked up her hips, allowing all of his seed to deposit in her bank. She let out a silent laugh, knowing that his seeds were within her once again.

She hovered over him, giving him another kiss. She grabbed his chin, letting him know of their status. "You're mine, Icchan! You are so mine and no bitch can ever touch this." She gave another thrust. "This dick, these sexy lips, your body, mine, and spirit is all mine." She licked his cheek before rolling off of him. She stood up as she reached for her panties. She was cautious as she walked in the dark. She took her birth control pills and then her morning after pills. After washing it down with water, she returned to her side of the futon. "Good night, you baka dog." She turned over.

As Izuku was getting adjusted, she spoke once more. "Sweet dreams, okay. Sweet dreams." Izuku wasn't fazed. It wasn't easy for Katsuki to open up since their confession to each other. As of now, they kept their relationship a secret. More so for the sake of the girls because Katsuki would become violent if any girl talked to him in a flirtatious manner. Honestly, anything.

It was rare that he received letters. If he did, Katsuki had to read for review. He must always meet Katsuki before and after school. They will hold hands when they go out on dates. Sleepovers were common, but it was to conduct their rendezvous. Katsuki was becoming risky when they have sex. It was as if she wanted to get pregnant. They have been fortunate with their close calls. Still, he wasn't ready to be a parent yet.

Izuku reached into his sheets. He felt the seminal residue on his boxers. Didn't want an explanation to his mother for laundry day, he decided to go and use the restroom. He wasn't worried as Katsuki was already sleeping. It didn't take long for the blonde to sleep. Amazing how that crazy girlfriend of his can easily get rest.

He got up from his futon and made his way out of the bedroom and into the hallway.

A few minutes later….

After using the restroom and cleaning off any seminal stain, he felt assured that he will be fine for another day. As he headed back to Katsuki's room, someone else in the house called his name.

"Icchan, is everything alright?" Katsuki's mother, Mitsuki, was sitting in the living room. The television was off and the lamp next to the couch was the only thing off. He looked away when seeing his girlfriend's mother's attire. She was wearing a tight black t-shirt and baby blue panties. To add to the fray, she was reading the book, The Story of O.

"I am fine," muttered Izuku as he wiped the sweat from his forehead. "Just had a dream and need to go to the bathroom to wash my face."

Mitsuki crossed her legs on the couch. Izuku had a clear and full view of Mitsuki's crotch. He looked down to avoid it. Unbeknownst to the emerald child, she was producing a smile. "Sorry, dear, with my attire. My husband isn't home and I didn't think you were going to be awake." She bowed. "Sorry for my attire." She reached for a throw blanket to cover herself up. "Hey, come keep me company for a little bit. I need to talk with someone before going to sleep."

Didn't want to be a rude guest, he entered the living room and sat on the couch across from Mitsuki. Mitsuki patted her side of the couch. "Come sit beside me. I don't bite." She winked at him.

Nervously, he walked to her side of the couch. He tried not to eye her breasts because her nipples were becoming quite perky through the shirt. He tried to think positively. Relax, Izuku. This is your girlfriend's mother. This isn't your first time seeing her like this.

"Comfy," she asked as she shared some of the covers with him.

He nodded silently, hoping that her sleep was drawing near.

"Your dream. Tell me what it was about?"

Izuku quickly forgot about that lie. He tried to be quick on his feet. Water. Water is wet. I was swimming in an ocean. Yeah, the ocean. I was being chased by a sperm whale. No, no, a whale. I was in the ocean being chased by a whale. Yeah, that's it.

"It was a wet dream," said Izuku without thinking. What the hell? "No, no," he tried explaining himself about the confusion.

Mitsuki covered her mouth, giggling at the stunned Izuku. "A wet dream?"

"No, I didn't mean it like that."

"Relax, Izuku. I may have a daughter, but these things do happen," she told Izuku. "Could you tell me about your wet dream?"

Running short on ideas, he needed to quickly answer. "It was a lie!" Why am I so nervous? Damn it?

Mitsuki produced a smile. "It's okay, Izuku. You don't have to be ashamed. Everybody gets them." She stretched her arm and placed it around his shoulder. "My poor little Icchan is embarrassed about having wet dreams. It's okay, dear. I won't tell anyone. Including Kacchan." She patted him on the back. "Consider it to be our little secret."

Izuku didn't want to say further. It beats not explaining the truth. A wet dream was a better excuse than telling the mother that he was porking her daughter in the nearby bedroom.

"Yes, ma'am," he nodded to her.

Mitsuki took Izuku's hand. "We are going to do a pinky swore."

"A pinky swore?"

"Yes, to be sure to keep this a promise. Okay?"

Izuku understood and wrapped his pinky around hers.

Pinky, pinky bow-bell,
Whoever tells a lie
Will sink down to the bad place
And never rise up again

Mitsuki kissed their pinkies, which made Izuku blushed. She added to the swear, "Finger cut-off, ten thousand fist-punchings, whoever lies has to swallow a thousand needles." She let go on his hand. "Promise now sealed."

Oh, God. I hope that I don't have to swallow a thousand needles. That what was probably Izuku was thinking as Mitsuki looked at his cute face. The mother wasn't stupid or wasn't born yesterday. The house was rigged with cameras to fit the occasion.

Earlier that day….

Mitsuki had to portray herself as the darling mother. Not the mother that wanted to bash her loving daughter's brains in with the tray she was carrying their snacks. Izuku was visiting for the evening. According to her charming prince, her mother was out of town for the weekend visiting his father. Feeling sorry for him, Katsuki begrudgingly brought Izuku over. She told him that he can stay over for the night (if he wanted to). He wasn't sure but nevertheless, the emerald cinnamon roll had pajamas and spare toiletries whenever he stayed over.

Mitsuki stood at her daughter's door. She had to rehearse her lines without wanting to smash her daughter's face with the glass that was starting to sparkle. Calm down, Mitsuki. That's is her man. She slapped herself on her forehead. Calm down, Mitsuki. That is her man. Her lovely beautiful man. That man that should be under my bosom and not that flatsy bitch of a daughter's. Calm down! They won't be doing anything. Except her breathing his air. Writing in journals, taking deep breaths, exercising, things that a therapist (or due to her cheapskate-ness, the internet would provide) should have done the trick for self-control.

But remember that the apple doesn't fall far from the tree. Her journals contained explicit threats on what she was going to do to her daughter. She nearly had a stroke after taking strong breaths to the point that her lungs were going inside out. The local gyms would no longer accept Mitsuki after destroying mirrors, elliptical equipment, and a punching bag that was scrawled with her hands. Die slut DIE!

"Kacchan! Icchan! Snacks!" Mitsuki pushed the door opened with her foot. The duo was sitting under the kotatsu watching Place to Place. "Oi! Mom, what are you doing without knocking!" The blushing Katsuki stared blankly at her mother. In return, Mitsuki did the same. If she knew her daughter like she knew her daughter, something was up.

"I was trying to let you know that snacks are served." She placed the tray of crackers, chips, and canned soda on the table. "Enough to make my precious little ones hungry and filled until dinner is served."

Izuku's smile gleamed at Mitsuki. "Thanks, Auntie. You're the best."

"Charming. You're very welcome." She smiled before staring daggers at her daughter. "You see, Kacchan? Icchan knows how to be nice, friendly, and presentable to mothers." She slapped her thighs. "If only my darling daughter dearest would do the same."

Katsuki rolled her eyes at her mother. "Yeah, yeah! Thanks for the snacks. See your way out." Mitsuki kept her composure. She knew that she had company. She held onto her apron as she badly wanted to use it to wrangle her little bitch of a daughter's neck. She held her breath, taking strong breaths. STRONG breaths.

"Very well, then," said Mitsuki. "I will see you guys enjoy and have fun." She winked at Izuku. "I will call you at dinner." Mitsuki bowed to the kids before stepping out of the door. You should thank God, Katsuki, that the Lord was on your side. I was this close from catching a case. But don't worry, Katsuki, I will let you keep for a day or so. But, know this! Izuku is going to be mine.

Meanwhile….

Katsuki scraped the tray of snacks into the trash can. She swiped the chips from her boyfriend's hand. "Ow! What's that for," asked Izuku.

"I'm saving your life, you baka," she said before kissing his hand. "I don't trust my mother. I knew you weren't paying attention, but when I see my mother that friendly, something is wrong." Katsuki stood up and dusted herself as she went into the closet. She opened her drawer and pulled out snack cakes and canned iced tea. She handed it to Izuku. "These are your favorites anyway," she said matter-of-factly as she crossed her arms.

"You know my favorites," asked Izuku as he eyed the treats.

She flicked his forehead. "Duh!" She knocked his forehead with her fist. "I am your girlfriend, silly. Of course, I know everything. What you eat, what you hate, what you hate." She blew into his face. "What you desire." She ran toward the door and locked it. In case, she grabbed her nightstand and pushed it against the door.

"Kacchan!"

"I feel like having a little fun." She slowly pulled off her skirt, exposing her cotton white panties. She swayed her hips, which she knew Izuku would automatically become hard. "Like what you see, you baka? Gonna blow a wad in your pants?" She didn't stop. She unbuttoned her blouse and dropped it to the floor. Then, she undid her bra, exposing her tits. She felt a bit uncomfortable with her tits. In comparison to her mother's, she was smaller. Nevertheless, she knew these breasts were for Izuku only.

And she meant. That included her goddamn mother. Clever, you bitch! Firstly, you aren't that nice to use name brand products. When seeing Coca-Cola, Wheat Thins, and Lays, you weren't slick. You are too much of a cheapskate to buy this so I knew you drugged these, you damn whore. You have a husband. Get your own goddamn man! Speaking of my man….

She produced a smirk, grabbing her booty as she made her way to Izuku. Izuku nearly dropped his baked good. "Take a break from your honey bun and get a taste of this honey bun."

"You don't mean."

"Huh, huh! You are going to literally kiss my ass, Izuku. Swear your allegiance, you baka. For you are mine."

"You have to be hard."

"And that's the way you like it."

Meanwhile in Mitsuki's private quarters….

Mitsuki had her hand in her panties whenever she was preparing for her sessions. Her husband was God-knows-where doing God-knows-what, leaving her alone with her lecherous thoughts.

She cracked a smile as she turned on to her new favorite show. A show in which her daughter was having sex with a certain lover that she was going to take from her daughter. She reached for the thickest plastic she had to null the frustration.

She needed something to vent as she was watching her emerald prince kissing her daughter's ass. Her eyes watered in frustration as she watched. That should his lips kissing her A-1 choice cut ass and not some damned rump roast.

Her daughter was more clever that she had thought. To think she had actually paid attention to her mother's shopping list.

"You clever bitch," she said to herself. "She learns quick. Like mother, like daughter." She fixed her lips. "That is okay. Please believe, baby. There are clever tricks up my sleeve yet. You are going to slip. Please believe. You will."

Back to the present….

"Izuku, there is something I need your help with," said Mitsuki.

"What is it," asked Izuku.

"Let's say...precious cargo," replied Mitsuki tenderly. "In the bedroom."

It was very lavish, he thought. Everything appeared antique, leaving him with a 19th-century feeling. He walked through the bedroom as she followed by him.

"So, what do you need help with," asked Izuku.

Click!

Izuku heard the door clicked shut. He turned as he saw Mitsuki blocked the door.

"Auntie?"

She produced a smile. "I know something you don't know." She began to undo her shirt. "And it involves a dream."

He swallowed the lump in his throat.

"And a little white lie," she said seductively.
