I'm just gonna say this now, this is a completely optional chapter. It does not have to be read. This was strictly written for fun and for people who kinda wanted it. This is also in celebration of me reaching 400 followers today, so thank you! Again this chapter was written for fun and is completely optional and doesn't have to be read. 

Warning will be posted when the time comes. I just want to say thank you for reading this book as the anime has been one of my all-time favorites. Adieu.

It was near the end of their senior year, and again, a prom was going to be held. PTO were quite leniant this time around, which was surprising this time around, but this time, the student council was responsible for planning the whole entire event.

Even if Y/N and Yukino wanted to help, Iroha denied their help, since they had been working so hard over the past few years, especially last year when they held two proms. In any case, it was about that time, it being night as they decided to hold the prom in the gym this year. Y/N was currently in his apartment, Itsuki having moved out to live with Shizuka, so it was now just him and Setsuna.

Y/N stood in front of the mirror, fumbling around with his tie as he felt nervous. Sure, he had danced with Yukino before, but as a kid, he didn't really feel the feelings he had now. At this point in time, Yukino Yukinoshita is now his girlfriend, and Y/N wasn't the best at displaying public affection towards her. If anything, he only shows the proper amount of affection for her in private. While Yukino herself does enjoy the affection he gives, she would like for him to show more in public to show that Y/N was hers and hers alone.

As Y/N kept nervously and awkwardly fumbling around with his tie, his older sister came up from behind and turned him around.

Setsuna: What are you so worried about?

Y/N: I-I don't know. I guess I'm just...nervous.

Setsuna: Oh, come on. You've danced with her in public before. Why are you shaking in your boots now?

Y/N: That was when we were kids! And we weren't dating at the time!

Setsuna only puts on a goofy grin as she pinches and pulls Y/N's cheeks, much to his annoyance. After she finishes fixing his tie, she pulls Y/N into a hug, Setsuna sighed happily.

Setsuna: I wonder what mom would think of us now?

Y/N: Probably be mad at us for distancing ourselves from "dad."

Setsuna: Maybe, but I feel should would be extremely proud of us. Especially you.

Y/N: Me?

Setsuna: Look at you now. You've gotten over of what happened and not only that, you've finally told her. I wasn't the only one who knew back then, you know.

Y/N: (looks away) Sh-Shut up.

Setsuna: Hey. Go have fun. And most importantly, make sure she has the best time in the whole world, okay?

Y/N: Y-Yeah. I will.

Setsuna: Good. Now, I have a little date myself so I won't be home till late. Make sure you grab the spare key to get into the house later. And another thing, make sure you two stay safe and no coming home late. Understand, mister?

Y/N: (sigh) Yeah, yeah. I get it.

Setsuna: Good. Now get on out of here so I can prepare for my own date. I've got a lady to seduce!~

Y/N: Yyyuuupp! See ya.

With a deep breath, he stepped out of his apartment complex and went to go pick her up. Arriving at her apartment, he rung the bell to signal himself to her. The doors open and he went up the elevator. Y/N awkwardly shuffled in his spot as it went up to the desired floor. 

Arriving at the floor he requested, he went to Yukino's door and rung the doorbell. As he waited, he kept checking his phone for the time constantly, which showed it was only 10PM. As he waited for a bit longer, he could hear the locks of the door being turned. Y/N straightened up, his attention now solely focused on the door. As soon as it opened, his eyes widened as he froze, a blush coming to his cheeks as he stared at the girl in front of him. Yukino stood in front of him in a beautiful white dress.

She could feel his gaze on her, Yukino rubbing her arm awkwardly as she would avert her eyes from time to time. 

Yukino: Wh-What...?

Y/N: I, uh...um...

Yukino: Does...does it look bad?

Y/N: N-No! It looks good! Really good! You, um, I...

Yukino: It's okay...I get it. (clears throat) Sh-Shall we be off...?

Y/N: Y-Yeah.

Yukino takes his hand, albeit a little shy, the two descended down the elevator to head towards Sobu High. When they arrived, the two would talk with one another before they slow danced to some music, but due to Yukino's light-headed experiences with large crowds, they had to leave early.

As he was walking Yukino home, she stopped and tugged on his sleeve of his tuxedo. Y/N stopped and looked at her confused.

Y/N: What's wrong?

Yukino: Can I...stay at your home? Just for tonight?

Y/N: Um, s-sure.

Leading her to his apartment complex, he unlocks, the whole apartment was dark as Setsuna had been gone for her own date. When he arrived in his room, he turned around and was met with Yukino's soft lips against his. While he didn't deny it, he was confused as to why she was doing this, as to why she wanted to spend the night now today.

She then released the kiss and looked up at him with expecting eyes, Yukino tugging on his tux.

Yukino: I want it off.

Lemon Warning. Stop reading now if you don't want to read this. Again, as I've said this before, this chapter has been completely optional and does not have to be read.

Although shyly, Y/N complied, Yukino assisting him as he took off the tux and leaving him in his white undershirt. Y/N's hands made it's way to the top of her dress, him slipping it off as Yukino looked away with a blush. Yukino's skin was now fully exposed to the cold air of the room, Y/N now having a full look of the black underwear she had on.

She pouted as she gestures Y/N to take off the rest of his clothing as well, not wanting to be the only one unclothed. Now fully unclothed, Yukino was leaning against Y/N as he was against the headboard of his bed, his left arm under her panties as his fingers went over her folds. She let out light moans as she does so, her breath ragged as she could feel Y/N's own hot breath against her neck. She turned her head around, capturing his lips as she slipped off her panties and went towards Y/N's underwear.

She pulled it down and her eyes widened at Y/N's large and impressive length. She blushed as she grasped it, stroking it as Y/N let out low groans in response. And then she started, bringing her head down as she brought her soft, delicate lips onto the head. A wave of pleasure caused Y/N to grip his bed sheets, biting his lip as Yukino continued to take his length into her mouth. Minutes passed, and Y/N released inside of her mouth, causing Yukino to take it out of her mouth and cough slightly. She smiled sweetly at him as Y/N rose up, brushing his thumb over her cheek as he captured her lips once more. His other hand went around her, going to her back as he unclipped her bra. The top part began to fall, only for Yukino to cover her small breasts and look away ashamed.

But Y/N had her face him, lifting her by the chin as she looked up at him. He gave a smile as she smiled back, nodding as she lied down on her back. As Y/N pushed his member towards her folds, he felt hesitant upon putting it in. Was this what she wanted? Looking at her once more, Yukino nodded and grabbed his hand, squeezing it tightly. With her permission, Y/N pushed forward, his member entering her folds as she scrunched her face in pain, causing Y/N to stop.

Y/N: I-I'm sorry. D-Does it hurt...?

Yukino: J-Just a little, but y-you can move now...

With a nod, Y/N thrusted slowly, Yukino making small moans as she moved with the way of his thrusts. The bed rocked and reeked with every thrust Y/N made, the two enjoying each and every second. Then Yukino flipped over, getting onto her hands and knees as Y/N thrusted from behind, Yukino's ever growing blush increasing as she was in such an embarrassing position. Grabbing both of her arms, he pulled them back, Yukino's eyes widening and her moans increasing.

Yukino: W-Wait...! Ah!~ D-Don't...this is...mm!~

Her tongue hung out as her breath once again grew ragged, Y/N continuing his thrusts as he increased his speed a little. Deciding that she could get a little bit of control, Y/N lied down on his back as he stared up at the beautiful girl he loved. Yukino bounced on his member, gripping one of his hands with the other on his chest for support. Her moans grew louder as she continued her steady bounces, Y/N encouraging her to take her time. 

Slightly tired, she slowed down and stopped, bringing her face down as she kisses Y/N. One of his hands made it's way to her breasts, softly caressing them as Yukino moaned into the kiss. A string of saliva connected them as the both separated, Yukino getting off as she leads Y/N to the door. She put both her hands on the door, Y/N coming from behind once more as he thrusts again, Yukino moaning his name as he increased in speed.

Her lips curved upwards as she panted, Y/N holding onto her to make sure she didn't fall. Unable to take it any longer, her legs gave way, Y/N quickly picking her up and putting her back on the bed. As he leaned downwards, Yukino lying on her back as he held his face.

Y/N: Y-Yukino...I-I'm--

Yukino: It's okay. I trust you.

She wrapped her legs around his waist, Y/N increasing his speed as he was getting close to climaxing. And with one final thrust, he lets go, his hot cum splashing into her as they both moaned at the same time.

After their workout, Y/N crawled into the bed with her, Yukino cuddling into Y/N's chest as he grabbed the blanket and brought it over them. Y/N kept running his hand through her long black hair, him humming before Yukino asked him a question.

Yukino: Y/N?

Y/N: Yes?

Yukino: Do you think...do you think we could have a family together?

Y/N: I would love to have one with you.

Her eyes started to become watery as a gentle smile made it to her face. She leaned up and pecked Y/N on his lips before she closed her eyes. Seconds later, light snoring could be heard from her. With a smile, Y/N kissed her forehead.

Y/N: I love you, my Ice Cold Queen.
