And after the day passed by, Y/N was sleeping for so long after got treated then for a while he's awake from his sleep

"Mmmm! *Yawns* Oh man!! I do love a very long nap!" Yn woke up from sleeping. "Man.... from fighting can really go through me real easily, I should do some training so I can get used to it." Yn said to himself as Yuuki walked in

"Oh hey Y/N~Kun, you're awake!" Yuuki said

"Hey Yuuki, what's up." Yn said 

"Nothing much, just waiting for you to wake up." Yuuki said

"Yep, and I need to get in the shower and stuff like that." Yn said 

"We got you some clothes from your house and some other stuff you need to get ready." Yuuki said as she got a bag with Y/N's stuff

"Thanks Yuuki." Yn thanked Yuuki

"You're welcome Y/N~Kun..... oh! Right I almost forgot, we'll help Aiko at 4:30." Yuuki reminded Y/N

"All right." Yn said as he got his bag to grab his clothes and look at his phone to see what time it is. "It's 2:10 already?!..... I'm really a heavy sleeper." Yn chuckles to himself as he goes to the bathroom and takes a shower

As he done with hygiene now it's 3:00 for Y/N was in the living room waiting until 4:30 hits. As he was waiting, Aiko suddenly approached behind him wrapping her arms around his neck 

"Heya Y/N~San!" Aiko sounded happy

"I know, I'm just happy that you and Yuuki are really helping me with this!" Aiko said as she moves closer to Y/N

"Y-Yeah..... and Aiko one question if you don't mind?" Yn ask politely 

"What is it?"

"Um? What makes you wanna learn how to kiss?" Aiko blush from hearing Y/N's question 

"Well.....I...... I just wanna know what it's like to kiss someone you like for once, y-you know how to experience it. Just like Yuuki kiss someone she likes and I wanna know when I'm going to get my turn." Aiko sounded serious but still have a calm and politely tone

"Oh! Well... do you like someone... like a secret crush?" Yn ask

"W-well I do like you the most." Aiko made Y/N blush. "But I don't wanna be a burden and get in you and Yuuki's relationship." Aiko said

"You won't be a burden Aiko, not to me or Yuuki. I mean I like you too cuz you're just being you and I really like it a lot and same thing to Yuuki as well." Yn was telling the truth as Aiko smiles to his answer

"Y/N~San.... you're really the sweetest, honorable guy that I ever met and that really makes me happy." Aiko hugs Y/N tightly 

"Y-Yeah..... I really appreciate that.... and you're squeezing my life out..." Yn couldn't breathe

"Oh sorry!" Aiko let Y/N go.

"It's ok.... hey I know Yuuki told me that you said until 4:30 but I'm kinda wanted to get started." Yn said

"Yeah me too.... well let's go get Yuuki and get this started." Aiko said as Yn agreed and head towards upstairs and knocked on Yuuki's door

"Hey Yuuki~ KNOCK KNOCK!!" Yn knocks on the door and didn't hear her respond. "Um? Yuuki... you're good?" Yn had entered her room and see something that surprises him. "Yo!! What the?!?!?~

Y/N sees Yuuki on the leaning against the wall shoving two of her fingers in herself and sinking her knees to the ground making Y/N completely shocked and speechless 

"Oh my goddd!" Yuuki moans loudly as Y/N and Aiko was watching her pleasuring herself like this.

"Oh my gosh!" Aiko whispered your Y/N, making him shivering 

"Y-Yeah you can say that again." Yn said

"Should we say something or what?"  Aiko ask Y/N

"I don't know..... but I might as well and do something." Yn said as he banged on the wall not too hard to let Yuuki know they were watching her fingering her self

KNOCKED KNOCKED!

"Huh!! Y-Y/N~Kun! O-Onee~Chan!" Yuuki was scared as Yn bangs on the wall

"Yuuki. Why are you fingering yourself?" Yn calmly ask Yuuki a question 

"I-I don't wanna wait anymore so I decided to pleasure myself.... I've been doing it for the past hour....." Yn was incredibly speechless at first then he broke it off

"Wow.... honestly.... it was really entertaining to watch that but yeah....." Yn was telling Yuuki the truth. "And we're planning on helping Aiko right now but if you're busy then~

"I'll join!!!" Yuuki quickly beat Y/N to it

"All right then~

"And we'll do it in our parents bedroom so let's go." Aiko said as she grabs Yn dragging him to their parents bedroom and Yuuki quickly puts on her clothes and rushed towards the room

"All right. Onee~Chan all you have to do is to get closer to Y/N~Kun." Yuuki said as Aiko got closer to Y/N

"What's next?" Aiko ask

"Well Aiko you could wrap your arms around me, well around my neck or cup my cheeks if you wanna, either I really don't mind of what you wanna do." Yn admits 

"O-Oh! Okay~

"And you can crawl on his lap, I do that all the time with him so I can have the advantage!" Yuuki said as she smirked 

"Ok....." Aiko had nervously got closer and tries to crawl on his lap but she's really scared but Y/N grab her and place her on his lap

"You don't have to be scared Aiko, I'm doing this cuz you ask for help and I'm helping you, so you don't need to be nervous y'know." Yn smiles at Aiko and she was smiling back

"Ok.... and what now?" Aiko ask

"And now you two lean closer and kiss each other and do whatever you two want but as long as I get some too though." Yuuki said as she was behind Y/N and watch ready to watch 

"Ok then... here goes..." Aiko lean forward and finally kissed Yn in the lips

SMOOCH!!!

As Aiko was perfectly in sync with Y/N for the first time. As she's kissing her friend, a boy who she's like for being himself and how he would fight to protect the around him with his life to make sure no one gets hurt or worse. She's giving Y/N everything she has in showing him of how she feel about him in every kiss she delivered.

"Mmmm! Ahh!" Aiko was moaning as she wrap her and around his neck and move her body closer and keeping her forehead connected with his forehead 

*Y-Y/N~San...... is really good at..... kissing..... now I can see why.... Yuuki love kissing him so... much..... because.... it's so good and it's really the best....* Aiko thought to herself as enjoying kissing Y/N

Then for a while, they both separated with sting of saliva connected. Y/N and Aiko was breathing really hard

"Wow Aiko! I completely didn't know you was this good?!" Yn said as he was surprise and Aiko was blushing 

"I-I didn't know either or it's just you don't know me that much Y/N~San." Aiko said as she teases him

"Yeah that's true. True." Yn admits 

"So.... what now?" Aiko ask

"For real?! Yes!!!" Yuuki was happily took of her shirt and hugs Yn from behind 

"So after we took of our shirts, we kiss and just go with the flow?" Aiko got the answer right

"Right! But things are gonna get in this threesome!" Yn said as they was ready to get things started 

Then Aiko and Y/N began kissing each other again, this time Aiko wasn't holding anything back as she was cupping his cheeks, delivered passionately kisses to Y/N and as he did the same thing but thanks to Yuuki making Y/N not going all out because she's marking his neck just he did to her for the first time. Then Konno sisters began to tease him by Aiko wrestle her tongue with his tongue to get the advantage and Yuuki marking his neck and licking the same spot, trying to corner him and it's actually working as he couldn't do two things at once.

"Ah! God you two are something else! I can't focus two things at once!" Yn said 

"Well, let's get down to the main course!" Yuuki said as she takes off her bra and skirt and now she's wearing nothing but her underwear 

"W-Wait?! W-We take off our bras and pants?!" Aiko's nervous about taking off more of her clothes 

"Yeah! That's the part of this whole thing." Yn said as he took of his pants and nothing but his underwear as well

"Sigh" O-Ok." Aiko had took off her bra and revealed her cute size breast and Yn couldn't stop staring at them 

*Woah!! Aiko's breast sizes are so cute! It's not too small or too big.* Yn thought to himself 

"W-Well... what do you think Y/N? Do you like my breast. It's not like Yuuki's though." Aiko ask Yn a question nervously

"I really like them Aiko. It's a really nice size." Yn honestly answer her question and she blush 

"Blush" "T-Thank you Y/N~San...." Aiko was happy

"Now it's time for action!" 

"W-Wait?!~

Yn had grabbed Aiko on his lap and kissed Aiko's left breast 

"Oh!!!" Aiko was surprise by Y/N's action but suddenly wrapped around her arms 

"Hey Y/N~Kun.... don't forget about me...." Yuuki said

"Oh don't worry because~

Yn grabs Yuuki closer and gently shove his two fingers inside Yuuki's pussy, making her arms as well

"Yes!! I love it when you shove your finger inside of my pussy Y/N~Kun!!" Yuuki was moaning

Then as Y/N pleasuring Aiko and Yuuki at the same time, the Konno Sisters was having their time of their lives, never wanted this amazing threesome to end. Then for a while they stopped.

"W-What's up?" Yn said

"Let's stop playing around get to the best part!" Yuuki said as she get rid of her underwear and Y/N did the same

"And I'll ride on his dick!" Yuuki quickly got on Cowgirl position

"You two are ready!" Yn said

"Yes!" The Konno Sisters said in unison 

Y/N started off with licking Aiko's pussy really gently, moving up and down motion, Aiko was keeping her moans in check. Meanwhile with Yuuki moving up and down, riding Y/N's Dick like the way she wanted. Then for couple of minutes the sisters started to act different 

"OH!! Y/N~KUN!!! PLEASE DON'T STOP POUNDING ME!!! IT'S SOOOO GOOD!!!" Yuuki shouted

*HE'S REALLY GOOD AT THIS!!!!* Aiko thought to herself as she bit her lip from screaming but she couldn't hold it in anymore

"OH FUCK!!! LICK ME ENTIRELY CLEAN!!!!" Aiko shouted

As Aiko and Yuuki's pussies were extremely wet, they almost couldn't hold their juices as they was too overwhelmed by the pleasure feeling. Then after a while, Yuuki was the first one who's close of releasing her juice 

"I'M GOING TO EXPLODE!!! I'M GOING TO CUMMMM!!!!" Yuuki release her cum as sloppy sounds developing as she couldn't bear her climax anymore. Then Aiko was about to experience the same thing

"SOMETHING REALLY BIG IS COMING! AND I DON'T KNOW WHAT IT IS?!?!?" Aiko screams twice louder than Yuuki as Y/N keeps licking her pussy more fiercely 

LICK! LICK! LICK!

"P-PLEASE DON'T STOP!!! I'M BEGGING YOU!!" Aiko's very close

As Y/N gave Aiko countless licks, Aiko couldn't hold the climax back anymore

"I-I'M........ I CAN'T HOLD IT ANYMORE Y/N~SAN!!! I'M GOING TO CUM!!!!" Aiko roars as she cums on his mouth, licking her entirely clean. "I REALLY LIKE YOU SO MUCH Y/N~SAN!!!" Aiko said before her last remaining juice consumed.

"Damn Aiko! You taste really good!" Yn made Aiko blush again

"T-T-Thanks Y/N~San." Aiko said as she rest

With the Konno sisters used up their organism so much, their body was completely drain and shaking from the anticipation 

"Oh my goodness.... I-I never felt something so really good like that before in my life." Aiko admit

"Yeah.... I really love it so much..." Yuuki said

"Yep! And now it's time for me to get pleasured now." Yn said

"W-Wait... y-you didn't cum yet?" Yuuki ask

"Well hey don't worry cuz now I'm going to enjoy my time pleasuring you two again!" Yn licks his lips to make the girls blush

"W-wait! How about me and Onee~Chan could do this!" Yuuki said as she laid Y/N down again and wrapped herself on his dick 

"You mean that position?"

"Yep! Cmon Onee~Chan!" Yuuki said as Aiko got in a scissor position.

"Now it's our turn Y/N~San/Kun!"The Konno Sisters said in unison 

"Hmph! Bring it on!" Yn said
