Y/n pov

After the battle with the World Breakers had ended everyone had begun the efforts to repair everything. During the months that followed The Soul Society had put the nearly all of the humans to sleep. None of us wanted them to remember the events that happened that day. However Ikumi wasn't willing to accept that and chose to remember. At first I wasn't hesitant on the idea but eventually chose to allow it. When the damage had been  fixed the people were awaken in their homes and had their memories altered. 

Y/n:*Breathes deeply* Ok today is the day...finally.

Getting ready with the others I prepared the a day I never thought would come so soon;the Graduation.   It felt like the 2 years we had left had passed quicker than anyone of us could've thought. Heading out into the living room I saw the others were ready to.

Izzy:*smiles* Man...things went by so fast. I almost began to think we'd never get to this point. 

Kiba: I know how you will Izzy these last few years have been a wild ride.

Ichigo: I'd say that's putting it lightly.

Nozomi: I may not have been here through everything with you all but I know that the last few months  is something i'm never gonna forget.

Senna: I feel the same.

Rias: You know it's kind of funny...for most people this is a point that everyone would strive for and be happy. Even knowing that I can't help but feel a little sad about it.

Gasper: But why Lady Rias?

Sona: I know where your coming from Rias I'm gonna miss the Academy too.

Tsubaki: The Highschool has shown us plenty of wonderful things and helped us meet plenty of people aswell.

Aika: Well we all did meet Y/n there too.

Murayama: I wonder what will come next in our lives?

Katase: I don't care as long as i'm with Y/n through it!

Rossweisse: All I know is that I've sworn my life to you all and our dear Y/n. So if giving up my role as a teacher is what I must do then so be it.

Irina:*Smiles* Hey let's try and remember the good times..we all knew this day would come anyways.

Y/n: Yeah Irina is right, all good things must come to a end someday. Our days as Students is over...and now comes the our first move into the future our lives.

Making our way out to where the graduation  was being held we faced the day we had been awaiting for years. When it was all over it was time for Rias to accept her new title as one of the 4 Satans.  Everyone was already prepared  all save Rias who tried to get mentally ready. When I saw her like that I leaned against a wall then spoke to her.

Y/n: You know being nervous ain't a bad thing? It shows you really do care for your people.

Rias: I just don't know if this is really a  good idea though. My bro-

Y/n: Sirzechs put his faith in you because he sees what I do in you. Even back when I was in your peerage you were a great leader. Rias let me tell you something most people don't seem to get. The thing about leadership is a great thing is shared with the same as anyone who makes things like movies,Videogames,Art,and books. The greatest ones hold doubt  about their path or creation.

Rias: I think I understand what you mean Y/n. Thank you so much for the pep talk honey.

Y/n:*Smirks*Heh Don't mention..now knock em dead.

When Rias walked out Sirzechs  stood beside her with Grayfia and his son.

Sirzechs: Citizens of Hell today I want to thank you all  for everything you've done. Over the years I've spent as one of the 4 rulers of Hell I had the honor of looking after you all. These years I've seen the rise of my great brother in law Y/n L/n into your Hero. I've watched the redemption of other noble households;and some of their falls. I even was able to see the beauty of the union of all factions. But with the invasion of the World Breakers i've come to a realization. I am not the leader you all deserve anymore.  I have failed you and have shown that I lack what it takes as a Husband and Father.

Grayfia/Millicas: Sirzechs/Daddy..

Sirzechs: It's with this in mind I'm stepping down from my role as a Satan and handing it to someone who's proven  her resolve to be great. I know this change maybe great but I have nothing but faith in her.  Please treat her with the same respect you did me  during my rule.

Rias Gremory...my little sister I know Hell will be in good hands.

Rias:*Smiles* Thank you Sirzechs I swear to you I won't let you down.

3rd person pov

While the people cheered Y/n grinned staring at Rias who blushed at their cheers.

Y/n:(Mind)  Congrats  Rias..you really do deserve this.

(LEMON WARNINGS HERE)

When the celebrations began Y/n and the others drank and enjoyed their time. As the hours soon went by Y/n wondered the mansion. During the time he did he noticed his room door open. Heading inside the man was met with the sight of 3 certain moms in wait;in skimpy outfits.

Ikumi:*smirks* Well looks who finally showed up~

Yasaka: *Giggles* Ah Y/n we were wondering when you'd arrive~.

Y/n: Well i'm sure as hell luck you all didn't have any other weapons than those Mommy Milkers. If so i'd be deader than dead.

Venelana: Well the three of us talked and came to a decision. You know Y/n you've taken great care of our children over these years. I know Rias especially calls you Daddy~

Y/n:*Smirks* Heh well so much for keeping the bed talk between us.

 The three women  walked around Y/n before undoing his shirt.

Yasaka: So we decided that today we're gonna take goood care of you~

Venelana kissed Y/n before she  sucked on his  bottom lip. After she stopped she licked her lips.

Venelana: By the way don't be afraid to call us Mommy after we begin.~

Y/n:*Smirk* Oho but one of you are wrong;cuz you'll be calling me Daddy too.~

Y/n french kissed Venelana causing her to hold his head.  Using his other hands Y/n started to finger Ikumi while groping Yasaka's massive tits.

Yasaka:  Ah~ I always knew you'd like these Aha~

Ikumi: F-Fuck Y/n~  You'd didn't hesitate for a chance to finger fuck your bosss~

While the women explored Y/n's body he returned the favor,feeling every once their sexy mature bodies.  Venelana and Yasaka pushed Y/n onto his bed before the  women stared on at Y/n's cock. Licking their lips with a lustful stare the got on the bed and crawled seductively to him.

Yasaka: So this is what the dick of Hell's Hero looks like?~

Yasaka and Ikumi licked it's head leaving Venelana to stroke his shaft.

Venelana: Ara~ I can see why Rias and the other's like it so much~

Y/n:(Mind) Oh fuck that not word. Ah shit~ The last time I heard that was when the Murder Mommy drained me dry!~

 Turned towards his bathroom door to see Kuroka walking out with a giggle.

Kuroka: Oh don't be so scared Y/n atleast I'll be gentle with you. Or do you want it rough huh~

Y/n: I knew it was only a matter of time before you came for some too.

Kuroka stripped from her uniform then stood over Y/n with a smirk.

Kuroka:*Smirks* Well you can't blame me can you?~ I can't let Shirone get greedy on me can I?~ 

Spreading her wet pussy infront of Y/n's face Kuroka giggled then spoke once more.

Kuroka:*Winks* Since that mouth of yours is free why don't I give you a nice meal~

 Grabbing the Nekomata's ass the Reaper began to lap away at her pussy. While Y/n ate Kuroka out he  stuck his tongue deeper causing her to moan loudly.

Kuroka: AH~ Now that's how Mama likes it~~

 Venelana  jerked Y/n off faster then began to finger herself;moaning out.

Ikumi: J-Just imagining getting fucked by that Dick is enough~

While minutes coming to pass Kuroka  finally came. Turning Kuroka around Y/n kissed her deeply allowing her to taste herself.

 When Kuroka got off him Venelana  brought herself down on  Y/n's dick then  grabbed his legs.

Venelana:  OOOh it's bigger than I could've ever imagined~ Zeoticus has nothing on Y/n's dick.

 Dropping up and Down Venelana began to ride Y/n's member. Soon giving into her lust Venelana stuck her tongue out as she moaned out Y/n's name.

Venelana:  AH OOH FUCK ME YES Y/N MORE!~

Fucking Venelana harder Y/n  started to suck Yasaka's tits. Causing both milfs to scream out with pleasure Y/n watched them collapse on his bed. Turning his attention to Ikumi who fingered herself on his bed Y/n made out with Ikumi before he rammed into her.

Ikumi:  Oho~ I don't care anymore! J-JUST FUCK ME HARD AND I'LL DO ANYTHING! GIVE ME ANOTHER KID Y/N~~

Y/n:*smirks* You wish is my command Ikumi.

Complying Y/n left her a moaning mess as he pounded her pussy until he left her pussy filled with his cum. When he finished Y/n got dressed then walked out after closing his door. Heading outside Y/n went into the healing  hot springs left on his mansion by Kisuke. Once he went inside Y/n let out a content  sigh.

Y/n: Man I should've thanked Kisuke for adding this sooner.

???: You have room for two more Y/n?~

Y/n looked to see Serafall and Sona standing by the water.

Y/n: Feel free girls.

After they took off their clothes they went inside and sat next to Y/n.

Serafall: Woah it's so warm in here it feels great!

Sona: Kisuke really did a amazing job with the Mansion.

Y/n: I agree it's awesome! But if i'm being honest being here with you and all the others make it just perfect.

Serafall: I think I know how we can make it better Y/n~

 Feeling Serafall  move her down his abs Y/n  grins.

Y/n: Well shit how did I know this would happen.

Serafall:  Aw come on Y/n Sona and I share everything ya know! Besides would you really turn down a threesome with 2 sisters?~

Y/n: As long as Sona agreed to it.

Sona: Your the only man i'd let this happen for Y/n.  If this were anyone else i'd have her leave here and now.

Y/n: Alright then if that's the case let's do it.

Serafall cheered before she kissed the man's face causing him to deepen the kiss.  After she stopped Y/n kissed Sona  while she caressed his face.  Kissing down Sona's neck to her collar down Y/n bite her gently;leaving a hickey behind. Sona moaned out leaving Serafall to suck Y/n's dick below the water. While she did Y/n  fingered away at Sona while he fondled her boobs.

Sona: T-This is what I wanted~ Oh show me the same love you showed Rias and the others!~

Serafall:(mind) Hehe~ Sona is having alot of fun with Y/n~

Y/n soon grabbed Serafall's head before he began to thrust into her mouth. Causing her to moan Y/n soon ate away  Sona's moist pussy with great speed.As the Springs filled with moans Y/n soon came in Serafall's mouth's mouth as Sona squirted on her sisters boobs. After Y/n let her go Y/n licked away Serafall's breasts; leaving Sona to french her for Y/n's cum. After sucking on the girl's tits for a few minutes the two of them stood over Y/n's dick.

Serafall: Hey Sona let's try something new.~

Sona: Alright.

 Before Y/n knew it the girls began to scissor  Y/n's dick  causing him to moan out. While they grind against Y/n's dick the three began to moan louder.

Y/n; T-This feels  amazing I feel like i'm gonna reach my limit soon.

Sona: So are we!

Serafall: L-LET'S DO IT TOGETHER!~

After reaching their climax the three cam in the springs. After Y/n got up he kissed Sona and Serafall one last time with a smile on his face.

Serafall/Sona: We love you Y/n.

Y/n: I love you girls too.

Timeskip brought to you by these

3rd person pov

Leaving the hot spring Y/n then took a shower. When he did Y/n found himself face to face with Rossweisse who was in a kimono.

Rossweisse: Hello Y/n is it alright if I join you?

Y/n: Uh sure thing Rossweisse.

After she joined him inside  it soon devolved into  a make out session, Wanting to end to get rid of his sexual instincts before they took over Y/n put Rossweisse against the shower wall then fucked her quickly. Thrusting as fast and deep as he could Y/n  finished then continued on with his shower.After he did he spent some time with Kunou and Gasper playing video games together. During the game  Y/n was met with Akeno wrapping her arms around his shoulders. 

Akeno: How does it feel finally not being a student anymore Hubby?

Y/n; Honestly it still feels too early for me to tell really. More importantly have you seen Rias? I checker her room earlier but she wasn't there.

Akeno: Oh she's out at a big event with her brother in Hell.

Y/n: I see well then I'm glad to see she's taking the whole Satan role well.

Akeno:*Giggles* You know Rias always trying her best. Speaking of which how are you liking your  gift so far?~

Looking at Akeno confused Y/n's eyes soon widened realizing what she meant.

Y/n: So all of the others are in on this?

Akeno: Yep we all thought it would be a great way to reward you for saving us all from the World Breakers. Speaking of which the others are waiting in the  training room for you~

Y/n: I guess it's time to just open this  gift quickly then~

Getting up and following Akeno Y/n was left with the sight of all the girls waiting for him.

Riruka: There you are finally! Y-You idiot we thought you'd never show up.
