Start of the Love Contract in the Family

"Now, we just need to give you a checkup to see if anything is wrong with you." Izuku said.

"Oh my…" Maria showed herself leaning on the wall just when Izuku and Mio exited the bathroom.

"It looks like you two are starting to get along pretty well." Maria grinned.

"What?! That's not true at all! What makes you say that?" Mio asked in shock, trying to play it off like nothing had happened between them.

"Besides the fact that Izuku is carrying you in his arms, it's written all over your face. Izuku is a pretty strong guy too!" Maria complimented.

"I'm not sure if I'm really that strong." Izuku proclaimed, a bit nervous with his power.

"Don't be modest. You negated my magic pretty effectively, didn't you?" Maria pointed out the moment in the living room earlier before she and Mio left the house for a while.

"Yeah, I was able to do that, but that was more of a lucky thing that I was able to do it at all since I've haven't really use it much in the years since my family's banishment." Izuku stated.

"Really? It looked like you know what you were doing and you're saying that it was pure luck that it worked out for you? What kind of technique was that?" Maria asked. Shocked to hear that Izuku hasn't used that in years.

"It's not really a technique. Just something that happened…" Izuku looked down, looking sad but he shook it off remembering that he has Mio in his arms.

"Anyway, I'm gong to take Mio to her room and check on her condition." Izuku said before walking away.

Sometime later, Mio is in her bedroom alone in nothing but the towel from the bathroom deep in her thoughts about Izuku with his kindness and the words he said after her failed attempt on taking over this house.

"Because it's the right thing to do. Not only that, but we're family. I did promise you that me and our moms are always going to be there for the both of you no matter what." Izuku's words echoed in her head.

"Family, I guess he's right." Mio started to see that now, the feelings of family when Izuku and the two moms welcomed her and Maria into the family.

Mio goes to a drawer to take out picture frame with the cracked glass and the picture of herself with her adopted parents, all three of them smiling together from the days they were together and unaware of her demon heritage for most of her life.

And she can still remember how her parents died with the father losing both his arms and exploding into flames and the mother being burned alive.

Mio whimpers of the very sad, tragic memories of that day when she lost everything she knew and the two most important people in her life, gone forever.

Her sad thoughts on that day were interrupted when she heard knocking on her door.

"Um. Uh, yes?" Mio asked as she placed the photo frame down on the bed, and the open door revealing that it's Maria.

"How are you feeling? Are you doing a little bit better now?" Maria asked concern.

"Yeah, I'm fine." Mio answered, assuring Maria that she is doing fine right now.

"Oh, good. Would you like some water?" Maria offered to get her some refreshment.

"No thanks, I'm really okay." Mio said.

It does look like Mio is doing okay right now, but Maria could always tell that something is bothering her and got the answer when she saw the photo frame of Mio's former family which is still fresh in her mind.

Mio gasp softly when Maria saw the photo knowing that she couldn't hide what she's really feeling now.

"Do you think… he really intends for us to be a family?" Mio asked as she looks at the old family photo.

Maria didn't say anything at first but instead showed her something on top of the old photo with a new one that shows of her and Mio together with Izuku and the moms, Sapphire and Raphaeline smiling.

"What's this?" Mio asked.

"Izuku printed out a copy for us to have." Maria answered, then started asking a question for Mio to answer.

"Do you think Sapphire ad Raphaeline and Izuku were just faking it, like we were all one big happy family?" Maria asked, Mio shook her head for no as an answer.

"Then why don't we just accept their kindness?" Maria suggested, believing this family is really something where they belong.

"The truth is, right now, you need every ally that you can get." Maria pointed that out as well.

Mio couldn't argue with that after escaping death from the attacker and Izuku showing so much kindness throughout the whole day and she can already tell that he is a wonderful boy who would go through many lengths to protect the ones he loves and do his best to make them feel happy.

She fully knows that everything is going to be alright for them, being in this big family that has started for them and perhaps helping her more than she realizes when Mio found out the truth back then.

"(Izuku, I want to be closer to you now. For us to be a family.)" Mio thought smiled at the photo.

"Great! Then everything's settled!" Maria smiled. Now she can bring out her plan.

"I've got a proposal! A very important proposal in the regards to our future!" Maria said with a grin.

"Proposal?" Mio wondered what Maria has in mind for this proposal and would it also have any effect on Izuku too.

"(Bingo!)" Maria thought smirked.

(Living Room)

Maria has called Izuku over into the living room without telling him the reason why he needed to come down to the living room and why she said to him that it was important, but he figured it wasn't a big deal.

Now he should've known that Maria was up to something when he is now standing on top of a gold magic circle with Mio as well while Ghislaine is just watching this from the sideline sitting on the couch.

"So, what exactly am I looking at?" Ghislaine asked.

"The Master-Servant pact magic." Maria grinned.

"I'm sorry, the what now?" Izuku asked, feeling very nervous about whatever is about to happen.

"Izuku, I would like for you and Mio to form a Master-Servant Testament." Maria requested.

"This is very confusing and so sudden at the same time! Why do me and Mio have to perform this pact?" Izuku asked.

"Oh, it's just a formality. Those whose souls are bound by a pact are able to sense each other better. I think that's something we should take full advantage of, so you'll be able to stay in touch and attuned to Mio's whereabouts." Maria explained the purpose of this ritual.

"Really? Like becoming a living GPS? That would be better in case our modern tech malfunction and probably respond better if she's caught in an enemy's trap." Izuku started to see that in those sorts of ways.

"See, now you're seeing what I'm getting at. I am so glad you could understand with that big head of yours." Maria leaned closer to Izuku, making him blush a little.

"But why are we doing this now?" Izuku asked.

"This magic can only be used on the night of a full moon. Tonight just happens to be a full moon, and we can't afford to miss this chance!" Maria pointed out.

"Oh yeah, there is definitely a full moon." Ghislaine nodded, remembering seeing the moon on her way here.

"(Oh man, this is something I can't just walk away from, can I?)" Izuku thought gulped.

"Huh, Mio, are you really okay with this? Forging a pact with each other?" Izuku asked, wanting to hear Mio's answer if she is really okay with doing this Master-Servant pact.

"Um… Yeah, sure, I'm fine with it, I guess. As long as… you wanna do it too." Mio looked at him with nervous and pleading eyes.

"Looks like she wants you to find her." Ghislaine believed.

"Well, if that's the case then I guess we're really doing it." Izuku decided to go with it.

"Right. So, we'll be able to find each other." Mio said, getting everything she just heard down.

"Great! Then it's all settled!" Maria clapped her hands together.

"This will be the first time you've ever cast magic, and I'll be right here to support you." Maria said, Mio nods with a smile.

"So, how does this pact work, other than just standing on top of the golden magic circle." Ghislaine asked.

"First, a magic circle will be formed on her hand. Then the pact will be complete once Izuku kiss it." Maria answered.

"Sounds simple enough, but me being the slave still feels weird and something else that I can't describe." Izuku commented.

Izuku felt something strange coming from his right hand and saw a glowing green magic circle appearing on the back of his right hand.

"Uh, Maria, there's a magic circle showing up on my hand. Is that suppose to happen?" Izuku asked.

Maria smiles sinisterly as her plan is coming together, something she had been hoping for to happen.

"Maria! What's the meaning of this?!" Mio gasped and demanded to know as she shakes Maria.

"Uh, wow! Well, that's pretty strange. I must have made a mistake—"

"Now what are we gonna do?!" Mio asked in fear and shaking Maria again.

"Let's just focus in on the goal to be aware of each other's whereabouts! So, if you will please, Mio… you can go ahead and kiss Izuku's hand now." Maria said, trying to play this off.

"You have got to be kidding! If you make me do that, then I'm the one who'll end up being his slave!" Mio pointed out in swear making Maria sweat nervously.

"Let's calm down and try to think this through." Izuku said, but he notices the magic circle on his hand is starting to fade.

"Huh, excuse me?" Izuku tried to get their attention.

"Do you mind? This is between us." Mio said.

"But this magic circle on my hand is fading." Izuku alerted.

"(Fuck no! This needs to happen now!)" Maria thought refused to let this opportunity go to waste.

"You better hurry up, Mio, before it's too late! Go smooch it!" Maria encouraged Mio to go kiss that hand and become Izuku's slave.

"But… I don't know—" Mio hesitated to go through with this when it was supposed to be the other way around.

"He can be released on the net full moon!" Maria pointed out.

"That's a whole month away. I don't know…" Mio still hesitated to do it.

"I'm sure we can think of something… Oh wait, it already disappeared." Izuku noticed the magic circle on his backhand is completely gone.

Maria whimpered in horror that her plan has been foiled by Mio's hesitation and fell onto her knees, if only she could've done this a little sooner then she could have had a little more time to make Mio kiss the hand like she wanted her to.

Mio sign in relief that she doesn't have to go through kissing his hand and becoming his slave, that would've been very awkward for her that's for sure.

But suddenly something strange happens to Mio as a magic crest appears around her neck like a magic collar of some sort.

"Hey! Wh-What's this?" Mio asked in shock, starting to feel something strange happening to her.

She whimpers as her body shakes from something that is happening to her on the inside, like there is a force that is starting to grow bigger and bigger with this unusual feeling that is suddenly making her feel hot but not in a way that is like being out in the sun on the hottest day and it's brutal as this hot feeling is different.

"No way… No!" Mio feared of what might be happening to her as she fell on her knees.

"Mio! Is everything okay? You look like you're in pain!" Izuku worried for Mio.

Izuku walked over to her to see if there is anything wrong with Mio, but the moment his hand touches her shoulder, Mio suddenly moans loud in shock.

"Okay, I can see that is not something I was told about!" Izuku gasped.

"Oh no! The curse is already taking effect!" Maria realized.

"Curse! What curse are you talking about?!" Izuku was shocked to hear that this is some kind of curse.

"Kid, I think you better tell us what is going on with Mio or else you might be waking up with thumbs." Ghislaine threatened with her red sword to her throat.

Maria chuckles nervously while fearing for her life on the inside, guess now would be a good time to explain what is going on with Mio and what Izuku has to do.

"The main purpose of a Master-Servant pact is to maintain the subordinate's loyalty. So, when the subordinate takes rebellious or traitorous action, the curse activates. Since Mio refused the kiss of loyalty, then most likely…" Maria paused for them to figure out.

"This curse is making her moan like she's in heat for lust." Ghislaine guessed.

"What? That's the curse right now?!" Izuku gasped.

"Yes, and despite my appearance, I'm a succubus." Maria revealed her true nature with her cheeks blushing.

"Oh, a succubus, that make sense." Izuku nodded and instantly went into complete shock. "You're WHAAAT?!"

"Are you seriously telling me that you're one of those lewd female demons that likes to go get any men they seen and do lots of fucking lewd things with them?!" Izuku asked with his face turning red.

"Huh, so you really didn't know this whole time. I already knew from the smell." Ghislaine tapped her nose, stating that she has a strong sense of smell to know what race a person is.

"How was I supposed to know she's a succubus?" Izuku asked.

"Well, what you said, it's slightly different than that. I sorta used my own magic in the pact, so Mio's suffering a succubus's curse." Maria began explaining while Mio is moaning erotically more.

"You mean you cause this on purpose?!" Izuku exclaimed.

"In other words, powerful aphrodisiac effects. It's a shame." Maria said.

"So, you wanted to have Mio feel pleasure but not with the curse." Ghislaine figured that out.

"How could you?!" Izuku yelled in worry at Maria.

"Help… You gotta try… Please help… There must be something you can do." Mio begged, struggling to keep herself down only for the arouse feeling to grow more.

"Please tell me there is a way to fix this?" Izuku asked.

"Not a problem. Rest assured. The curse is alleviated when the master makes the servant submit." Maria said.

"I have to make Mio submit to me? How?" Izuku was confused.

"That part' simple. All you have to do is touch Mio." Maria answered.

"Touch her? You mean…?!" Izuku gasped upon realizing what Maria meant by having him to touch Mio.

"Right now, the aphrodisiac effects of the curse are making her senses hypersensitive. She's never felt such pleasure. So, if you touch her for a while, she should obediently swear her loyalty to you by her own free will." Maria explained the best way to help ease the curse on Mio.

"Hey! What do you think you're saying?!" Mio asked in shock. This sounds like Izuku is going to do something to make her feel more than what she's already experiencing.

"It's all right. Just try and bear it a little bit longer. I'll have Izuku come and relieve it for you soon." Maria promised.

"It's not like I want to watch your expression when Izuku brings you to the peak of excitement and you just can't take anymore." Maria grinned.

"You're making a face that says exactly what you want." Izuku pointed it out, but Maria chooses to ignore that.

"Well, Izuku, go ahead! Please relieve Mio by touching her in her embarrassing places." Maria gestured to Mio's breasts.

"So, I have to t-t-touch her anywhere to help stop the curse?" Izuku asked, just wanted to make sure.

"You can. However, the longer you take, the more her mind and body will suffer. Mio will ascend to Heaven in both senses of the phrase!" Maria answered while Mio lets out some more moans again.

"I thought devils go to Hell when they die." Ghislaine said.

"Oh man, I can't believe something like this is really happening and I'm the only one who can save Mio…" Izuku gulped with his hands shaking, but he stops them with a clutch knowing what he has to do.
