The Costume Party: Itto and Miss Hina (Com)

 A commission for Last_of_workers

Willow was working on her Itto costume in the living room while her boyfriend Dustin was in the kitchen making dinner after he lost a bet with her. They planned to eat before heading out to walk around since they didn’t really have plans for tonight.

They were just going to hang out together as a couple, but then Willow got a text from Turner about a party. She intently told him she couldn’t come since she was with Dustin today and he wasn't a part of the Genshin group, and she didn't want to abandon him.

Then Turner then invited Dustin saying it was a good chance to finally get him into the game and their group like Willow had wanted. Willow smiled at that, it was true she really wanted to share all of it with him, and Dustin had been trying to get into it.

Willow went into the kitchen and told Dustin about the invite. He was okay with going, but he said he didn’t even have a costume, never mind one from Genshin Impact. Willow told him not to worry about it, as she had a ton in her closet that would fit him.

He said he really didn’t want to wear a costume, but Willow loved to bet and gamble, and she was very good at egging Dustin into taking bets and gambles with her, so she took out a coin and asked him to flip on it.

He decided to take the bet and called tails while the coin was in mid-air. He of course lost. Willow told him to grab one of her costumes from her closet after they ate. He agreed and they sat down to eat. After that, they cleaned up, went to different rooms, and began to change.

It wasn't until Willow was nearly fully dressed up that she realized something. This was the first time she cosplayed a male character, which meant all the costumes she sent her boyfriend to pick through were all female characters.

She knew he’d be too embarrassed and emasculated to wear one of them. So she was prepared to take off her Itto costume and let him wear it, but before she got to her bedroom to tell him, Dustin had picked out one of her costumes and put it on. That costume was Miss Hina.

Willow had to cover her face to surprise her laughter and her excitement to see her boyfriend wearing something so cute. Dustin noticed her and asked her what was wrong. Willow got her composer back and said nothing.

She then asked why he picked that costume. Dustin looked down and said the rest were all female characters and there was no way he was wearing them. Willow held back another laugh. Dustin then said that he recognized the wig for this one.

He said he’d seen this cat boy in memes she sent him. He then said as different as it was, men wore kimonos as well, so this was the best choice. It was clear he didn’t know the difference between male and female kimonos

Dustin seemed okay with it and he was pretty happy, so Willow couldn’t bring herself to tell him the truth. So now that they both had a costume, they headed off to Turner's house to enjoy the party. They arrived to find the party already quite lively with people.

Turner came over and greeted them as they arrived, Willow could tell he was holding back laughter looking at Dustin but chose to be polite and tell him he looked good. Then he looked at Willow and said her new costume was super impressive and looked like Itto was actually in the room.

Turner told them there was food and drinks, and Willow looked at Dustin and smiled, they both knew what was going on, and without saying anything they started to play rock paper scissors. Dustin once again lost and went off to the kitchen to grab some drinks.

Once he was gone, Turner asked Willow what was up with the costume. She told him about the bet to make him wear a costume and lied saying she picked it out. She only did that to make it less embarrassing for Dustin should he ever find out the truth.

Turner walked away and Imain came over to talk to Willow just as Dustin came back with a drink for him and Willow. They talked for a bit and Dustin got another compliment on his costume before Imani left for the kitchen.

Dustin followed Willow around like a loyal puppy as she greeted the rest of the group. Then she got him to sit in her lap on the recliner and watch her as she played Genshin with Kristin, Penelope, and Cohen.

Willow was doing daily missions with the group while explaining different aspects of the game to Dustin, who was actually starting to seem impressed with the game. They were both having a good time, which was ruined when a bright light filled the room blinding them all.

Dustin wasn't sure what was going on, but she felt herself going up as if Willow had somehow started growing larger. When the light finally passed through the room, everyone was able to see again. Dustin and Willow were looking into each other's eyes.

It was clear to them that the other had changed, but before they could say anything Ariel’s mech came to life. Willow jumped up to his feet, causing Dustin to fall straight onto her ass on the floor. Dustin then stood up and rubbed her butt.

She then looked at Willow again who was completely amazed by the Ruin Mech. Dustin followed her gaze to it, and was a bit confused on what it even was, some sort of robot? Then Beckhamed screamed and everyone looked at her.

Everyone was amazed that Beckham had become a real Paimon, but even more so that she was floating. Dustin hadn't even noticed that part and just learned in close to Willow and whispered asking what character that was, and who that was.

Willow looked down at Dustin just realizing how much of a height difference was between them now, and answered. He told her that it was Beckham dressed as Paimon. Then explained that Paimon was the little helper in the game.

Dustin seemed satisfied with that answer and then placed her hand on Willow’s stomach without looking. That caused her to quickly turn back and look at him. She just realized that Willow’s abs were real.

Willow confirmed it and said that it seemed everyone in the room had transformed into their characters. Then he asked Dustin if she hadn't noticed her own changes. Dustin raised an eyebrow and said no, then asked what was different about her.

At that time everyone had split up to check themselves out, so Willow grabbed Dustin’s hand and pulled her over to a different room. The first thing Willow did was confess the truth about Dustin’s costume.

He watched as Dustin turned bright red and looked down at her Kimono. She then playfully hit Willow in his chiseled abs asking him how he could let her walk around dressed as a girl all night. Willow apologized again but said there was another more important problem.

Dustin asked what it was. Willow then explained that even though the character didn’t really exist in the game and was based on a male character, it seemed the magic that transformed them only cared that the character was presented as female.

Willow watched as Dustin’s eyes got wide and she looked down. Dustin grabbed her chest finally realizing breasts had grown on them. She let out a little yelp followed by turning red, but there was something else that Willow didn’t expect to see.

Dustin now had a trial because of her transformation, and after grabbing her own breasts it started to wag back and forth as if she enjoyed what she had just done. Willow noticed and teased Dustin about it.

Dustin turned bright red, then crossed her arms. Saying they needed to change back right away. Willow then asked what the rush was, they were cool characters might as well have fun with it. Dustin started pouting a bit and asked what kind of fun was there to be had like this.

Willow then grabbed Dustin by the hips and pulled her in close. Willow then said for starters they could feel what it was like on the other side of things. Dustin felt her beating fast as all these new sensations came flooding in.

Her chest pressed against his rock-hard body felt incredible. He was holding her so close and tightly making her feel so tiny but super safe. Her heart was beating and something deep inside her wanted him to kiss her.

He slowly moved his head down to see if she was into it, and when she didn't pull away she went ahead and planted a long kiss on Dustin’s lips. Dustin’s tail starts wagging like crazy. After their kiss, the two smiled at each other.

Dustin admitted the kiss was nice, and him holding her was also nice, but she still wanted to turn back. Willow asked Dustin to make a bet with him, Dustin rolled her eyes, Willow and his gambles. Dustin asked him what he had in mind.

Willow bet that they’d have a great night in these bodies, and if they didn’t they’d find a way to turn back, but if they did, Dustin had to agree to stay like this. Dustin asked why she’d take a bet like that. Will said because it was a win-win situation.

Dustin thought about it and he was right, if they liked being like this why not stay? If they didn’t, of course, they’d find a way to reverse it. Dustin took that bet and told Willow to show her a good time, especially if she wanted to stay like this.

The two went out and joined the others. Shortly after the group discovered they had powers and they started to mess around with them. Dustin and Willow were in the backyard. Willow was using his claymore Redhorn Stonethresher to break rocks he had summoned.

Dustin had been watching since she was under the assumption she didn’t have any powers since she wasn’t a real character, but after watching for a moment she playfully lifted her hand up. To her surprise, a bow had appeared.

She stood up and shot it at a rock that Willow was about to break, shattering it to pieces before he could. Willow turned and looked at her, she was holding the Favonius Warbow and had a big smile on her face.

Willow then invited her to join him and break rocks with their weapons and powers. Dustin happily jumped up and did so. The two even did some practice battles with some of the others. Eventually, it got late and the two of them left, still in their new bodies.

They decided not to worry about it tonight and to just cuddle. For the first time, Dustin got to be the little spoon, and she absolutely loved it. She wouldn't admit that, but Willow could tell because her tail wouldn't stop moving. The following morning the two were talking about the night before.

They were also talking about where they stood on turning back when they got the message from Turner saying they were stuck like this. The two talked about it for a bit, and both agreed it would be easier to adapt to their new bodies than to find a way to turn back.

So the two were going to stay like this, and stay a couple, and to make things better they didn’t even need to do shopping for their new bodies, they just decided to swap wardrobes since the fit was pretty close to their new bodies.

That also means that Dustin had a bunch of girly costumes to try out, and Willow was determined to get her into one. So she challenged Dustin to another bet. If Dustin could put on her Ganyu without getting excited or being happy about it, she’d do all the chores for a week.

But if Dustin did get excited she’d have to wear the costume as Willow made a woman out of her. Willow was suppressed at how quickly Dustin took the bet, and how quickly it took for her to lose, almost like she did it intentionally.

They then hopped on the bed and awkwardly figured out how their new parts worked. So that’s it for them, they’ll adjust to their new bodies, and go about life as they have been, and if the other needs anything or even has questions about their new body, the other will be there to help.
