Hey guys new Chapter!

So I wanna shout out to Tohka123 for that comment! It really helped me cause I was a bit afraid of continuing this story so thx to your comment I will continue it!

Also check chapter 1 for warnings if you forgot.

BTW I don't own IS because it is owned by Izuru Yumizuru but I own the OCs.

When the kids got home they went to the kitchen and saw a note that Ichika was at the I.S. academy. For unknown reasons they couldn't figure out why he was allowed to in the academy grounds even though it was strictly forbidden for boys or men on it's premisis.

After the kids finished eating their sandwhiches and drank their lemonades they went to the living room and hung out. It was hot during the afternoon so they couldn't go outside and they were bored. It was then someone came up with a question.

"Hey guys do you ever wonder why our parents don't let us in their room?" Kyou asked being second oldest

"They probably have something in there. It's their privacy so we shouldn't question it." replied Kazou the youngest

"True but I still wonder, don't you want to know what's in there?" Madoka the oldest asked asked

"Well we're not gonna find out if we lay around. Let's go!" Youta the second youngest jumped up

"I disagree. This is their privacy and we should respect that." Kazou said trying to talk some reasoning into them

What he got was ignored as the other three climbed the stairs and went towards the room making him sigh and follow the three. They slowly opened the door and looked inside. They saw two dressers and a large king sized bed. The curtains were tied to the sides letting the noon sunray in. The room was very well kept as there was no dust on the drawers and the bed was made. All in all the room was very neatly made.

"It's so clean in here." Youta said

"This must be dad since our moms aren't really the clean type." Madoka said

"Yeah but it looks like an ordinary room so lets get out of here." Kazou encouraged

"No way! We just got here. Lets look around for a bit." Kyou said

The three split up and they all went their own ways digging through drawers. Madoka decided to go into the walk in closet and dug through some stuff and saw some wedding pictures. There she saw the three of them near a beach and them doing different poses in different shots.

"Hey guys I found some wedding photos." Madoka yelled

"Oh nice! I haven't seen a single picture of their wedding yet! Let me see!" Exclaimed Kyou excitedly

"Here." Madoka said handing her the picture

"Woah is that dad?" Kazou asked

"Yeah but why's he wearing the bride's dress and mom wearing the suit?" Asked Kyou

"I'm not gonna lie. I'm a straight guy but seeing dad in that makes him look really hot." Youta explained

This made the other three to take slow steps away from him while they sweat dropped.

"Oh come on guys! You know I'm right! Look at him! Slender arms, thin body that is wrapped in the dress tightly, and the blush!" He tried to explain

"Well he's not lying about that. Dad does look good in it but why is he the bride. But it does make sense now why he's the one staying at home while mom is the one going to work." Kazou deduced (No Offense to anyone! I believe in gender equality! 2017!)

"Well lets look around for more things." Youta said as they went back to searching

With Ichika

After helping Yamada sensei carry the books to the library and catching up the last 18 years he started his trek towards Chifuyu's room. He walked down the long hallway with some students walking and talking the other directions from him. He then finally reached a door with the sign 'Orimura Chifuyu' on it. He knocked on the door and got a 'come in' from the person inside. Opening the door he could see a huge stack of paperwork on the desk.

"Chifuyu-nee I brought you the food." Ichika said after closing the door

"Thanks Ichika and I haven't heard you call me that in a long time." Chifuyu said with a smile

"Just because we're married doesn't mean you're not my sister anymore." Ichika said

"Well thank you and I've been feeling vvvvveeeeerrrrrrry frustrated lately. Could you help me with something like that?" Chifuyu asked as she got up from her desk and walked towards Ichika

"Suh Sure... what do you have in mind?" Ichika asked blushing red because even after all these years both Tabane and Chifuyu could still make him blush easily

"Oh... I have a feeling you know what I'm talking about." Chifuyu said pushing her lips against against Ichika's while also pushing him back towards the door. With her free hand she locked the door and pulled Ichika's head towards her to deepen the kiss more.

"MMmmmmmhhhhh! Chifuyu-nee!" Ichika moaned out

"Calling me your sister while we're doing this?" Chifuyu asked as they seperated

"It's kinky and I like it." Ichika smiled at her with a blush

"I also like it." Chifuyu said as she pressed her lips against Ichika's once again. This time Chifuyu start to undress Ichika from his clothes while he does the same to her. After they were only left in their birthday suits Chifuyu pushed Ichika down on the floor.

"You know, you still have the same effect on me since I came here 18 years ago. I was so happy to be closer to you." Ichika said

"I was also glad you were coming here since I couldn't be close to you after having to stay in Germany." Chifuyu confessed

"But I believe it was halfway through the school year when we went to that resort that I finally accepted my feelings for you." Ichika also confessed

"I'm glad you did or else we wouldn't be here right now. It's funny how we're married for almost 16 years and have four kids and this is when we decide to confess when we fell for each other." Chifuyu said

"Well it was this school that helped me fall in love with you so I believe that this is the perfect place." Ichika said

"Well then. Enough of that because I'm aching hard right now and I need your mouth on it." Chifuyu said with a smirk as Ichika turned even redder from her use of words

Ichika nodded and turned the other direction underneath Chifuyu getting in the 69 position. He licked the top of the head a few times before he went and sucked the entire dick in. He took the first 6 inches first and then took the rest in. Mean while Chifuyu was licking ferverously at Ichika's slit making him moan sending pleasurable shivers up her body. That went on until Chifuyu decided to stick a finger inside of Ichika making him gasp and moan out.

"Ahhh! Chifuyu-nee!" Ichika moaned out

"Close already Ichika? I know we haven't done it recently but this is quick for you." Chifuyu commented

Ichika didn't answer as he continued to moan as Chifuyu's fingers curled inside of him teasing him.

"Please don't tease me Chifuyu-nee!" Ichika cried

"Fine since you brought me lunch." Chifuyu spared Ichika as she pinched the bundle of nerves making Ichika scream out

This made Chifuyu worried since people would start to come inside and question her and she was incredibly hard right now. Thinking quickly she unlocked the door and put back on her suit while getting Ichika and his clothes under her desk. Once he came to the door opened revealing some teachers and security guards with their weapons ready.

"Miss Orimura we heard a scream are you alright?" Asked a guard

"Yes I'm fine right now." Chifuyu said

"We'll need to make an inspection. You could sit right there." The guard said

Chifuyu looked under her desk to see Ichika look up at her. With his face she couldn't resist she pulled his head towards her standing dick and made him start to suck on it. After pushing his face down a few times she let him go and he continued himself. After a few more tense moments the guards and teachers left the room.

As soon as the door closed Chifuyu picked Ichika's light body up and positioned him over her. Then she plundged Ichika down onto herself. She started to bounce him quicker as his eyes rolled back and tongue stuck out with drool coming down.

"Ahhhh! Chifuyu-ahhh-nee shouldn't mmmhhh we lo lock the door?" Ichika struggle to say

Instead of answering she placed Ichika on the desk thrusting into him faster and bent down to his eye and said, "Well then you better keep quiet or else someone would walk in."

Ichika moaned and got even wetter at the thought of getting caught in this lewd position with his sister. She was thrusting into him while she pulled his arms back bending him over her desk.

"Are you getting wetter thinking of getting caught? You naughty naughty boy." Chifuyu teased

Suddenly the door opened up and in came a sweating Tatenashi with her fan. In the last 18 years she has grown into a beautiful woman. She has taken over as head of her Clan's company but wanted to work at the I.S. academy. She is now taller than Ichika and has a large chest. Her hair she decided to keep the same as before and wearing a slightly different pair of clothing to differentiate her from the students.

"Miss Orimura I came here as fast as I could when I heard someone say that they heard... a... scream... from... here..." Tatenashi said before slowing down seeing the sight before her

"Ahhh!" Ichika half screamed from shock of being caught and half from having another orgasm

"Tatenashi please come back in a bit when we're more dressed." Chifuyu commanded as she pulled out of Ichika

"Oh- Okay." Tatenashi obeyed and left the room quickly with a red face

"I'll help you get dressed." Chifuyu said as she went to pick up both of their clothes

"Tha- Thanks Chifuyu-nee." Ichika replied red faced and sitting on the chair

After the two were finished dressing Chifuyu called Tatenashi back in.

"Hey Tatenashi." Ichika greeted shyly

"Hey Ichika. Now what happened? You disappeared for what? 18 years? Now you should up and doing that with your sister?" Tatenashi asked her face glowing red a bit near the end

"Well how should I say this... we're married." Ichika replied timidly

"What! How were you able to do that? That's not even legal here." Tatenashi retorted

"We married in secret. It was a three way wedding so we couldn't do it at somewhere public. We just had to sign some papers and we were officially married." Chifuyu explained

"We at least had a nice honeymoon." Ichika added

"So please keep this a secret. I don't people to know about this. It could ruin nee-chan's career." Ichika begged

"Don't worry. Who you love doesn't concern me." Tatenashi said

Both Ichika and Chifuyu gave a sigh of relief. They then made small talk which was mostly Ichika and Tatenashi about the 18 years. Soon though Ichika had to get home to make dinner.

Ichika got back on the train physically exhausted and waited for the ride home. Halfway through he got a phone call from Tabane.

"Hello?" Ichika asked

"Ick-kun! Sorry about this but I'm not going to be able to eat your food tonight! WAHHH! I will be home really early tomorrow morning though so have a good night." Tabane said

"Thanks Tabane and remember to take some rests to." Ichika reminded her before hanging up

The rest of the train ride was silent and peaceful. When he finally arrived at the station he got off and quickly went back home. It was close to 6 pm currently so the kids would be waiting for him to make dinner. Entering the house he slipped off his shoes and shouted, "I'm home!"

"Welcome back dad!" They all replied to him

"I'm going to be making dinner and your moms are not going to be home tonight for dinner since their work wouldn't allow it." Ichika informed them

"Okay dad!" Youta replied

Ichika went to the kitchen and gathered the ingredients. While doing this he saw a note and picked it with it reading:

Come to the pier tonight at 11 pm.

Remember what you are and what

would happen to your kids if you don't

M

Ichika sighed at the note. He hated how he was so weak back then.
