Trevor was never a very masculine guy, and throughout his life he’s never even made a ton of male friends. Most of his friends are female, with his three closest friends, Lina, Myah, and Kaila, being female.
Because of that, sometimes he feels a bit awkward hanging out with them because they like to go shopping for cute clothes or get their hair done. It’s not like he hates those things; he mostly avoids it in order to not make his friends feel awkward having a guy around.
Of course they’ve told him time and time again that they were more than comfortable with him around and don’t mind, but he still avoided those situations anyway. Well, his friends felt bad that he missed out on fun activities, so they decided to hold a sleepover and make Trevor join them.
They told him it was just a small party for the group, so he didn’t suspect anything until he walked into Lina’s place and found four sleeping bags laid out on her living room floor in front of her television. Around it were makeup and clothes, games, and snacks.
“What’s going on? Are you guys having a sleepover?” Trevor said as he looked at the area they set up. Kaila snuck behind Trevor and closed the door, while Myah came right up to Trevor with a big smile on her face.
“Yes, we sure are.” She said as she grabbed Trevor’s hand. Trevor turned bright red and started to panic. “I uh… I can’t be… Here… this sort of….” Trevor stuttered, trying to focus on speaking, but he was too nervous to do so.
Lina sighed. “Trevor, we’ve told you it’s alright. At this point you’re basically one of the girls anyway. We know you and trust you.” She said. Kaila came up from behind and hugged Trevor from behind. “We know you’re not a pervert, so we have nothing to worry about,” she said while laughing.
Everyone sat down on a sleeping bag, and they looked at Trevor. They clearly wanted him here, and Trevor has never gotten to do something like this before, and he had always wanted to go to a sleepover when he was a kid but couldn’t.
“Al… Alright… if you say it’s okay… I’ll stay…” Trevor said as he sat down. Everyone celebrated that, and Lina grabbed the remote and turned on a romance movie for them to listen to while they hung out.
They chatted for a bit before they all looked at Trevor. He turned bright red. “Wh.. What?” He asked. The girls looked at each other and smiled. They then each grabbed something from the supplies around them.
“What… What are you going to do with all of that?” Trevor asked as he started to think about running away. “Just a bit of a makeover, nothing to worry about.” Kaila said as she came closer with a hairbrush.
“We’ve wanted to do this for so long!” Lina said with some makeup in her hands. “You’re going to look so cute when we’re done.” Myah said as she came closer with a dress. They then surrounded Trevor and got to work.
He was too nervous to move or say anything, so he let them do it. They undressed him completely, leaving him nude for a few moments, which meant his manhood was on full display for them to see, but they didn’t once glance at it or even seem to care about it.
After several minutes of work, they had Trevor’s hair done, added a bit of makeup to his face, and put him in a cute dress. He didn’t exactly look exactly like a girl but was definitely looking like a cute femboy. Trevor was too embarrassed to say anything, so the other just moved onto playing games.
They played a few normal board games before Myah pulled out some strange box. “What is that, Myah?” Kaila asked as she got a closer look at the box. “It’s some magical box I bought from a witchcraft store.” She said as she hit the button and caused the box to light up. “How does it work?”
Lina asked, seeming excited for whatever it was. “Well, it’s a magical truth or dare box. The gameplay works like normal truth or dare, but if someone lies or fails to complete the dare, the person who asked the question or gave the dare gets to change one thing about that person.”
Myah said as she placed her hand on top of the box. “To play, you have to put your hand on it like this. Then you simply say, I’d like to play.” Myah said," The box then started to glow. “Player accepted.” The box said in a strange tone.
Everyone, including Trevor, was impressed, and one by one they each put their hand on the box and entered the game. Then came time for Trevor to put his hand on it. “Come on, Trevor, this will be super fun; put your hand on it.” Myah said,
The others agreed and convinced him to play. He still wasn’t sure, but he didn’t think this was real, so it shouldn’t be that big of a deal. He put his hand on the box. “I’d… like to play…” He said slowly. “Final player accepted.” The box said.
The box then started to glow, and then it flashed green. “Player Lina goes first.” The box said. “Yay! Me first. Now who should I pick?” Lina said as she looked around. She stopped when she looked at Trevor and smiled.
“You seem like the perfect person to try this box out on. How about it, Trevor, truth or dare?” Lina said, Trevor thought about it. Questions were simple to answer since he could lie, but embarrassing dares were not.
“Truth…” Trevor said. Lina smiled. “Alright. Is it true… That you like the dress you’re in?” Lina said with a smile on her face, Trevor turned bright red. “No… No way. I’m a guy; why would I like it?” Trevor said, not realizing his bright red face gave away his lie.
“Player Trevor is lying.” The box said as it flashed red. Everyone started laughing while Trevor put his hands on his face. “Player Lina, make your choice about how to change player Trevor.” The box said as it turned blue.
“Hmmm, I wonder if this thing can actually do that. Maybe we should try it out with something crazy. How about you give Trevor a more feminine body? Like, make him slightly curvy.” Lina said, looking into the box. “Change accepted.” The box said.
The box flashed, and the whole room was blinded by light. When it vanished, everyone looked at Trevor and gasped. Trevor opened his eyes and looked down; he then joined them in gasping. “The… the box actually works!” Trevor said quietly.
He was now looking down at himself. His hips were now wider, while his waist was much slimmer, which made him actually look girly in the dress he was wearing. “That’s amazing! I can’t believe it worked!” Myah said.
“I can’t believe how cute Trevor looks.” Kaila said, The box flashes green again. “Player Kaila’s turn.” The box said. “Sweet! Myah! Truth or dare!” Kaila asked, Myah picked dare, and Kaila dared her to take her bra off and wear it as a hat for the rest of the game.
Myah had no problem doing that. She lifted her dress, removed her bra, showing her boobs to everyone in the room, then lowered her dress back down. She then put the bra on her head and smiled.
After Kaila, it was Myah’s turn, who then asked Kaila. Kaila picked truth and when asked if she’s used any vegetables to pleasure herself before. Kaila proudly stated she had, three times, then named each one she tried.
The group laughed, and Trevor joined in a bit but was still embarrassed about his body. It finally came down to his turn. “Player Trevor’s turn.” The box said. “It’s my turn…” Trevor said as he looked around. He wasn’t sure whom to pick.
The only person not to be asked so far was Lina. “Lina… Truth or dare…” Trevor asked." Lina looked up and thought about it, then looked at Trevor and smiled. “I chose dare.” She said. “Oh… okay… I dare you to…” Trevor slowly looked around as he spoke.
He found that among the snacks was her most hated thing to eat, nuts. She wasn’t allergic; she just hated them. “Eat a handful of nuts.” Trevor said as he pointed down at them. Lina looked at them, then looked back at Trevor.
“You got me; I’m not doing that.” She said with a smile. “Player Trevor, make your choice about how to change player Lina.” The box said. Trevor thought about it for a minute. “Uh, how about you dress Lina like a clown?” Trevor asked, not knowing if that would work.
“Change accepted.” The box said. The room filled up with light, and when it vanished, Lina had a colorful wig on, clown clothes, and a big red nose with clown makeup underneath it. Everyone laughed, including Lina, who was enjoying honking her nose.
“Round two. Order shuffled. Player Myah’s turn.” The box said. Myah smiled and looked around; she then stopped at Trevor and smiled. “Truth or dare, Trevor?” She asked. Trevor gulped. The last round was bad for him; he didn’t want to be asked any more embarrassing questions.
“Dare.” He said. Myah smiled. “I dare you to take your dress off and leave it off.” She said with a perverted look on her face. Trevor turned bright red and looked down at himself. She clearly just wanted to see Trevor’s new figure.
Trevor also knew that if he didn’t do it, she’d be able to change something else about him, which he didn’t want, as he had no idea what she’d change. “Fi… Fine… I’ll do it.” Trevor took the bottom of the dress and removed it.
He dropped it on the side of him and moved his hands over his crotch and looked down embarrassed. The girls gave him some looks, and they seemed quite surprised. The box then announced it was Kaila’s turn, so their attention went back to the game.
The Sleepover Game: Pt2
Trevor sat embarrassed as his friends took their turns. Kaila’s turn was next, and she asked Lina, Truth or dare? Lina took truth this time and answered Kaila’s question honestly. After that it was Trevor’s turn again.
Trevor was having a hard time making eye contact because of how embarrassed he was, but he managed to do it long enough to pick. Trevor asked Kaila this time. “I chose dare!” She said confidently. Trevor then thought for a moment.
“I dare you… to act as a loyal servant and call the rest of us master for the rest of the night.” Trevor said. “Yikes… I mean, I could probably do that…” Kaila said, thinking. Myah cleared her throat. “You mean you could probably do that, master.” she said while giggling.
Kaila looked over at her and pouted. “Yeah, no way I’m doing that. Just go ahead and punish me.” Kaila said as she put her hands behind her head. “Oh… Uh… I guess I’ll change your outfit as well. How about a cute bear costume with bear mittens?” Trevor said.
“Change accepted.” The box said again, “Oh, come on, Trevor. You could have done a lot worse than that. Don’t you want to see me in something sexy? Like a topless maid outfit? So that way my massive boobs are showing?” Kaila says as she plays with her boobs.
Trevor turns bright red, and the room fills with light again. When it was gone, Kaila was actually wearing something quite sexy. It didn’t cover her legs and had a large boob window, as well as big, poofy paw gloves and bear ears.
“Nevermind… This is… quite embarrassing to wear.” Kaila said as she turned bright red. The other two girls started laughing while Trevor panicked a bit. “I didn’t mean… I didn’t know it would…” Trevor stutters as he feels like he may have messed up.
“Don’t worry about it; I know you’re not a pervert. This box, on the other hand.” Kaila said with a smile. “Player Lina’s turn.” The box said. Lina smiled and looked right at Trevor. “I want to know more of your secrets!” She said with a smile.
“What? Wait, no, I have to pick first.” Trevor said, panicked. “Oh, right. Well, if you pick, dare I say, I’m going to give you something you can’t beat. So pick truth.” Lina said. Trevor looked worried. He was trapped. He either had to reveal something or get changed.
“I guess… I guess I chose truth…” He said reluctantly. “Yay! Alright. Now, is it true that you like my boobs more than the other two’s?” Lina said. Trevor turned bright red and looked around. The other two clearly wanted to know the answer.
Trevor could easily answer that, but he felt like the other two would be mad at him. So now his choice was to tell the truth or lie and get changed but not have his friends be mad at him. “I uh… I think they’re all… great…” He said, knowing full well they knew he was lying to avoid the question.
“Player Trevor is lying.” The box said. Trevor looked at the box and gulped. He then looked at his friends, who were all staring at each other with intense looks, but then suddenly it went away and they were all laughing.
Lina then looked at Trevor and smiled as the box told her to pick a change. “Well, since Trevor can’t pick between these three good chests, how about you give him a pair of his own and make them super big.” Lina said.
Trevor’s jaw dropped. “Wait… You can’t...” Trevor was cut off by the box flashing. When the light went away, Trevor felt two very heavy things pulling his chest down. He looked down to find he did in fact have massive breasts.
“Whoa…” Lina said. “I have… I really have breasts! You gave me breasts!” Trevor said, panicking. “They’re so huge…” Kaila said. “They look so grabable.” Myah said as she tried to touch them, only to have her hand swatted by Trevor’s.
“I can’t believe you did this to me!” Trevor said, looking upset. The others realized Trevor was seriously upset and paused the game to comfort him. “I’m sorry; I was just messing around.” Lina said. “Yeah, it’ll be okay. After this, we’ll play another game and turn you back to normal.”
Kaila said with a smile. “Yeah, that’s right. So for now, be the luckiest guy in the world and enjoy the best boobs in the world. Remember, we’re just having fun.” Myah said. Trevor calmed down. “Yeah… You’re right… I’m sorry, I just got overwhelmed.” Trevor said before taking a deep breath.
He then smiled. “Of course, now this means war. I won’t be nice.” Trevor said confidently. Everyone laughed, and the game continued. Trevor got to go first, and this time he asked Myah, who failed to complete her dare.
Trevor smiled as he got revenge for his massive breasts by giving Myah the biggest butt. That started a whole round of everyone getting crazy new changes. Kaila asked Lina who failed her dare and was made to wear a bunny girl outfit.
Myha asked Kaila, who chose a dare and lost on purpose just so she could get a change. She ended up with very thick thighs, which she seemed to love and kept offering to let people take a nap on.
Trevor was asked again by Lina, and he lost, and this time they thought it would be funny to make his cock bigger by making him a futa girl. Trevor’s cock grew nearly ten times bigger, while the rest of his body got a bit more feminine and thicker as a side effect of the futa change.
He wasn’t as embarrassed about it this time, though he was still slightly embarrassed about not having any clothes, but thanks to everyone else just having a good time and showing him it wasn’t a big deal, he was actually moving past it and having fun.
As they were laughing, the box flashed a few different colors. “Final round. Double choice changes applied to losers.” The box said. The group looked surprised, and they all looked at each other and started to get devious smiles on their faces.
“Player Trevor's turn.” The box said. Trevor smiled and looked at Lina. “Well, since it’s the final round, and you picked me every turn. It’s only fair I get you back a bit. Don’t you think so?” Trevor said while smiling,"
Lina let out an awkward laugh and nodded. “That’s fair… I’m… I’m going to pick truth.” Lina said. “Is that so?” Trevor said as he put his hand to his chin. “Alright. Is it true… That you like women more than you like men?” Trevor said.
Lina’s face turned bright red, and she looked down. Everyone else then looked at her, expecting her to say no since she’s never mentioned such a thing to them. Lina looked up. “I… I don’t know how you know about that… but yes… it’s true…” Lina said, almost seeming relieved.
“Player Lina has told the truth.” The box said. Everyone looked surprised and Trevor’s jaw dropped. “That’s so awesome, girl!” Kaila said as she hugged Lina. “That’s so cool! I officially invite you to the gay club!” Myah said while also hugging her.
Trevor closed his mouth. “Lina… I’m so sorry.” Trevor said as he lowered himself to the floor, as close as he could get thanks to his breasts. “I had no idea. It was just a joke… Well, it was supposed to be… I didn’t mean to make you come out like that.” Trevor said, sounding genuinely apologetic.
Lina smiled. “It’s okay… I’m glad it’s out there now. Not hiding it will be so much easier.” Lina said as she patted Trevor on the head. Trevor got back up and smiled. “Of course, I do have to get revenge now.” Lina said with a smile. “Player Lina’s turn.” The box said, followed by Trevor gulping.
The Sleepover Game: Pt3
“So, Trevor, what do you pick? It’s your choice. Either get ready to admit something super embarrassing or prepare for a near impossible dare.” Lina said, smiling. Trevor gulped and looked at the others, both of whom didn’t seem to have any pity for him.
“I guess… I’ll take a dare.” Trevor said nervously. “Great! I dare you to let me play with your breasts for one straight minute.” Lina said as she made a grabbing motion with her hands. “WHAT! No… no way!” Trevor said as he covered himself.
“Oh? All right then. I have two changes perfect for you.” Lina said. Trevor pouted. “Fine, I’d rather have that than you touching these things.” Trevor said in a semi-pretend pouty tone. “Player Trevor has failed his dare. Player Lina chose two changes.” The box said.
“Okey dokey box. I want to make Trevor’s body more milf-like. So let’s make his hips wider and his thighs much thicker.” Lina said to the box. “Changes accepted.” The box said before blinding everyone with light again.
Trevor opened his eyes to find he was even sexier than before. “Wow… I really am hot…” He said. “Yeah, you are, and it seems your futa cock agrees,” Kaila said as she pointed down at it. “Yeah, that thing has to be fully erect now.” Myah said.
Trevor turns bright red and laughs. “Yeah, it sure is throbbing now. Though just seeing a girl who looked like I do now would have my old one doing the same thing.” Trevor said as he rubbed his head. The group laughed and all agreed it was totally understandable.
The game continued. Next up was Kaila, and she turned towards Trevor and picked him. “Wait, you’re picking me as well? You guys just really want to mess with me before we change back, huh?” Trevor said, pretending to be annoyed.
The group laughed. “Yeah, I do. Now pick so I can make you lose and add my own changes to you.” Kaila said as she rubbed her hands together. “Fine, fine, just for fun. I’ll pick dare and just forfeit to give you your changes.” Trevor said.
Kaila smiled and waited for the box to catch up. “Alright, box. I want you to get rid of Trevor’s futa cock and make him a real woman. I also want you to make him extremely horny when he changes.” Kaila said.
Everyone, including Trevor, was surprised. “Wait… wait a minute… Isn't that a bit much?” Trevor said nervously. “Ah, come on, you have to see what the whole thing is like; you may never get another chance like this.” Kaila said.
Trevor gulped and nodded. “Al… alright… I guess… You’re right…” Trevor said as he watched the box and waited for the changes. The light flashed and Trevor looked down. She couldn't see her cock anymore, so she knew it was gone.
She moved her hands down to her and touched it. She then immediately fell to the ground and started panting. “Huff… Oh… My… it… it… feels… so…” Trevor could barely think. All her mind had racing through it was finding some way to pleasure herself.
“Wow, this box really does crazy changes.” Lina said as she held her bright red face. “Yeah, perhaps we should get this game over with and change Trevor back to normal.” Myah said. “Oh boo, she looks so sexy… But maybe you’re right.” Kaila said, disappointed.
“It’s my turn now. So… Trevor… truth or dare.” Myah asked her. Trevor turned her head towards Myah. “What… Why… me?” Trevor asked, trying her best not to focus on her arousal. “Might as well, right? The next game will be to turn you back.” Myah said as she shrugged her shoulders.
Trevor just sighed and picked truth. Then lied about the question so Myah could make her last two changes. Trevor did that hoping to get this over quickly and change back so at the very least she could put some clothes on.
“I’m not even sure what to change. You’re already a thick, horny milf.” Myah said as she looked at Trevor. Myah then looked at the others, looking for suggestions. “I don’t know. Her body is amazing. You could dress her up.” Kaila said.
“Or maybe some mental changes?” Lina said. “Mental changes?” Myah asked, Lina nodded. “Yeah, since it’s only for a minute. Make Trevor think he’s always been a girl and perhaps even like it.” Lina said.
“Whoa… Wait a minute… I don’t know about that…” Trevor said. “It’s not a big deal, right? She can do that; we’ll have some fun playing with the fully female you and then turn you back and have the memories forever.” Kaila said with joy.
“That sounds amazing. We’ll get tons of pics and vids. Alright, that’s what I want box. Make Trevor think she’s always been a girl, and make her love being a sexy woman.” Myha said. “Changes accepted.” The box said.
Trevor stood silent as she waited for the box to light up. Once it did and vanished. She sat there staring blankly. She then looked down at herself. “Huh? Nothing changed? Did the box break after all of that?” Trevor said, confused.
The rest of the group began to giggle and got their phones out. Just then the box flashes white. “That concludes the game. Thanks for playing.” The box said before vanishing into thin air. Myah, Kaila, and Lina looked down at it, shocked.
Trevor just looked at it confused. “Where… Where did it go?” Kaila asked. “I… I don’t know… The store clerk never mentioned it would do that.” Myah said nervously. “Well, what do we do? We need that to…” Lina stops talking as she looks at Trevor.
The other two look at Trevor as well. Trevor notices and tilts her head. “What? Is there something on my face?” Trevor asks as she turns bright red. The rest of the group look at each other and look worried.
“The shop is closed for the night… So I can’t even go back and get another box…” Myah said. “So, we’re stuck with a female Trevor who thinks she’s always been a girl?” Kaila said. Trevor still had no idea what they were talking about.
“Female Trevor? Who thinks she’s a girl? I mean, yeah, I’m female and I’ve always been one. You guys are being so strange right now… Also… Is the game over? Can I put on some clothes? Being nude is super embarrassing, you know.” Trevor said as she awkwardly rubbed her legs together.
The rest of the group shrugged their shoulders and smiled. “Let’s deal with it in the morning.” Lina said. “Agreed. For now, I think it’s time for a bit of dressing up, don’t you think?” Kaila said. Myah nodded. “I have the perfect thing for her to wear!”
For the rest of the night the group dressed Trevor up in many different outfits, did her hair and makeup a ton of different ways and took enough photos and videos to last a lifetime. After a couple of hours, most of them fell asleep.
Trevor was the only one who remained awake. She snuck off to the bathroom to satisfy some intense arousal she’d been feeling all night. She sat on the toilet, spread her legs, and stuck a few fingers inside herself.
She had to use a towel to bite down on in order to keep herself from moaning loudly, and when she finished, it took an hour to clean all of her cum off the toilet seat, but once she was done, she felt amazing and had no problem drifting off into a blissful sleep.
In the morning the group dresses Trevor up again and brings her to the shop where Myah bought the box, but when they arrive, they find it has been replaced by some laundry mat. The others question Myah and ask her if she’s positive that was the spot.
She confirms it and says she knew it was. The only explanation they had was that, like the box, the shop was magical as well, and it was possible they’d never see it again, which meant Trevor was going to be stuck as she currently was.
The group looked at Trevor and asked her a few questions. She didn’t remember being a guy and she said she liked being a girl, but despite that, she still seemed to have her same personality and memories, just altered to remembering it as a guy.
The group shrugged. It didn’t seem all that bad for Trevor to stay like this. As a girl, Trevor couldn’t exclude herself from the fun things they do because she doesn’t want to make them uncomfortable, which meant she could accept herself as one of them, as they had done years ago.
So with that, Trevor’s first sleepover ended with him becoming a girl, gaining some form of acceptance for herself and getting to do all the fun things her friends did without her, which was currently shopping for cute clothes that actually fit Trevor’s new body.

I'm not sure how I should feel about this story... On the one hand, I feel sorry for Trevor, because he was turned into a girl essentially against her will, and I doubt that he would have agreed to this game if he had realized ALL the consequences of this decision, but on the other hand, I'm glad that he went through this path completely, because it would have been much worse if he had been stuck in the body of a Futanari girl or if the changes in his mind had not worked, then he would have ended up in the body of a girl but would have retained the mind of a guy... On the one hand, this way he would have remained himself, but on the other hand, I doubt that he needed this... In general, I'm not sure that it would have been better for him...
