A very strange and confusing situation! They don't seem surprised at all! So many strange situations!

You lowered your gaze and sighed in frustration. The blouse you were wearing still revealed two breasts, and you noticed you still had a feminine figure, and your hair was still long. So you looked at Mikan and Yami and sighed again. "Damn it! I'm still the same!" you said in frustration, noticing your voice had changed a little. "When Lala gets back, maybe she can fix it!" you said resignedly, shifting uncomfortably. "I should have known it wasn't a good idea to wear that thing!" you complained aloud, frowning.

Mikan approached you, along with Yami, and gave you a comforting look. "Come on, don't worry, little sister! I'm sure Lala can fix it. For now, just be patient! It could have been worse!" she said, trying to console you. Then, she looked at you with a slightly more amused expression. "At least it's just that one thing that's grown! But make sure Lala, Risa, and Mio don't see you with that erection before they get back!" she says, smiling at you, and together with Yumi, you head for the bedroom door.

Still flustered, you frown at your sister's words and blush as you realize how hard your penis is and how it's showing through your shorts. "It's not funny, Mikan! Your clothes are way too tight on me! And besides, they're still really uncomfortable!" you huff.

Mikan and Yumi stop in the doorway, and Mikan turns around with a puzzled look. "What's wrong, Riko? You just have to wait a little while, and it's not like they're that tight!" she finishes, looking at you seriously. "Besides, we're the same size, so just put something on from your closet, okay?" she says finally, before leaving with Yumi.

You freeze, trying to process Mikan's words, until you finally speak. "Riko?! What the heck?!" you blurt out nervously, before rushing towards the stairs, past a confused Mikan and Yumi, and up to your room.

When you arrive, you quickly open the door and go inside. Looking inside, you let out a small gasp of surprise and disbelief. "What the heck?!" you exclaim incredulously, before turning to Mikan and Momo, who had arrived after hearing the noise. "Can you tell me what you've been doing in my room?!" you demand seriously.

Looking around your room, you notice that the walls, once dark green, are now light blue, like Mikan's room. Your wardrobe is still there, next to your desk and bed, but you see a girl's school uniform neatly folded on your bed. Beside your bed was a small crib, and inside your open closet was a full-size girl's wardrobe, overflowing with all sorts of clothes. Looking in the drawers, you found only girls' underwear; there was no boy's clothing. But what truly took your breath away was seeing yourself in the mirror. Although you still resembled Mikan, you didn't look quite as much like her anymore, and you simply looked older.

Mikan and Momo came in behind you and looked around, confused, before approaching you, puzzled. "What do you mean, Riko? We haven't touched anything, it's just as messy as ever!" Mikan said resignedly. "The only thing we touched was your uniform, which, as usual, you left scattered everywhere!" she said scoldingly, while Momo, beside her, nodded.

Hearing this, you looked at them, bewildered. "Could you all stop joking around?! And please, stop joking about Riko, okay?!" you say, frustrated, as you head to your bed and pick up your uniform. "Besides, you know perfectly well this isn't... what the heck?!" you start to say, but stop when you see the name tag: Riko Yuuki.

Wanting to confirm you weren't imagining things, you go to your nightstand and look for your ID. Your eyes widen when you see yourself in your current form, with the same name: Riko Yuuki. Looking through it, you find several photos of yourself with Mikan, in which you both look like twins. The most surprising thing is that you see photos you've never seen before, from your childhood until now, and in all of them, you appear as a girl. There are also many where you appear with Lala, Haruna, Risa, and Mio. In all of them you were smiling, and in quite a few you appeared affectionate, or kissing Lala, and in some with Momo and Nana.

Once you recovered, you turned to Mikan and Momo, who were looking at you curiously. "Well, talk! What kind of joke is this?!" you said in a very annoyed tone, with your hands on your hips, and then you looked at Momo. "If this is one of your jokes, you'd better stop, or I'll tell Lala when I get back!" you said in a warning tone.

Momo frowns and looks at you, completely confused. "What are you talking about? You're acting really weird!" she huffs. "Besides, what are you talking about? I haven't done anything! I've been out almost all day. Besides, you didn't complain yesterday, did you? And Lala already warned you, and I don't think she'll blame me!" she finishes, before heading for the door.

You're about to say something when Nana comes in. "What's wrong with you two now? What did you do to Riko?!" she asks Momo, frowning. Then she looks at you, huffing at the sight of your shorts. "Okay... So that's why? Because of Momo's nonsense. You haven't gone back to normal, have you, Riko?" she says, nodding.

Hearing this, Momo looks at her sister, and they start arguing as they leave your room. You're left with Mikan, who shakes her head in resignation before looking at you. "If you're not saying weird things anymore, I recommend you take a shower!" she says in her usual motherly tone as she turns around. "I was going to take a bath too. If you want, can I join you?" she adds casually.

You look at her in surprise, but nod without knowing why. She waves back and finally leaves the room, leaving you alone and wondering what the hell was going on.

————-

You were still bewildered when you finally stepped into the jacuzzi. You didn't know what it was, and what you saw only filled you with more confusion. It seemed that all your old clothes had disappeared, and the photos you had before, although the same, were slightly different, now showing you as a girl.

You were pondering this, noticing with unease how hard your penis was, when the bathroom door opened. You looked up and saw Mikan enter calmly, a towel draped over her shoulder, completely naked. "Mikan! What are you doing?!" you exclaimed, looking away.

Mikan looked at you calmly and, setting her towel aside, approached the bathtub. "What do you think, Riko?! I'm coming with you, can't you see?!" she said casually, before getting into the tub and sitting opposite you, sighing contentedly. "Mmm, this feels so good!" she said with her eyes closed, watching herself relax.

You were speechless and on the verge of complaining, but finally decided to say nothing and tried to relax as well. You both lay peacefully for a while, helping each other wash and chatting about unimportant things. Finally, getting out of the tub, you wrapped yourselves in towels and went to get dressed.

--- Half an hour later ----

When you left your room, already dressed, and headed for the stairs, you were still lost in thought. Going downstairs, you're wearing green pants and an orange blouse: the most neutral outfit you could find, because you wanted to find out what was going on.

As you get downstairs and head towards the living room, you hear voices coming from there, and you recognize them as Lala, Risa, and Momo. You quickly go over and see that Lala, Risa, and Mio are sitting on the sofa, talking calmly with Lala, while on the other sofa, Momo and Nana are still arguing.

As you enter, Lala turns to you with a smile. "I see you're calmer now, huh, Riko?" she says cheerfully as you approach. Risa and Mio make room for you and smile at you. "You should have come!" she says happily when you sit down with them.

You look at them nervously, noticing Risa and Mio smiling at you. "Um... yeah, the bath did me good!" you say uncertainly, then you look at Lala and gather your courage. "Hey, Lala! The joke's over, right? It's not funny anymore! And please, fix this mess!" you say seriously, pointing at yourself and, most importantly, showing off your bulge.

Hearing you, Lala looks at you with disappointment and puffs out her cheeks, but finally smiles at you, while Risa and Mio look at you mischievously. "Ohhh, come on, Riko, you don't have to be so serious, do you? After all, I warned you not to do anything weird!" Lala says in a scolding tone, and then looks at you with a playful smile. "Besides, I don't understand why, while I'm trying to make your dick disappear, we can't have some fun," she says, as she puts a hand on your crotch.

Hearing Lala, you look at her, now very alarmed. "You're joking, right, Lala? Can't you see something went very wrong? Don't you see? Look at me!" you say, as you put your hands on your breasts. "And don't you dare say... mmmhhhh!" You try to speak, but you can't finish, because you let out a moan as Risa's hands move to your breasts and begin to caress them. "Risa, stop, please, it's not...!" you say, shuddering with pleasure.

Risa looks at you amused, pulling you closer as she laughs. "Come on, don't be shy! After all, we know you're enjoying it!" she says, kneading your breasts and playfully licking your ear, smiling mischievously as you moan with immense pleasure when she squeezes your nipples. "Look, you're the same as always, and your body says it all!" she says enthusiastically, as Mio joins Risa and puts her hands on your pants.

You can't help but moan as you enjoy this, but you look to Lala for help, and she looks at you with an amused smile. "At least go to your room!" she says playfully, while Momo, who had stopped arguing with Nana, can be heard laughing in the background.

You finally manage to escape from Risa and Mio. "Stop, please, it's not the time!" you say nervously, earning a disapproving look from Risa and Mio, but they nod.

More calmly, you start talking with Lala and the others, discussing their plans for tomorrow. You'd known for days that they were going to take advantage of the fact that it was Sunday and you didn't have classes on Monday to go to some hot springs with Yui Kotegawa, Haruna, Momo, Nana, Mikan, and Celine. What caught you off guard was when they mentioned you and told you not to forget anything, and that since you'd have to get up early tomorrow, there wouldn't be much time.

You didn't know what to say, since you knew it was just girls there and that it had been difficult for them to reserve a table. Even so, you dismissed that and reassured them. After that, Celine appeared with Mikan, and while Mikan informed you that dinner was ready, Celine approached you and gave you a small hug.

You returned the hug, and you both got up to go to the table. Once there, you sat down to eat, chatting quietly and forgetting for the moment the strange situation you were experiencing. Risa and Mio were going to stay in the guest room, so you were going to go to your room to rest.

As you were heading for the stairs, Risa took your hand and smiled at you. "Where do you think you're going, Riko? I told you before, tonight we're going to have fun!" She says mischievously, as she, Mio, and Lala lead you toward the guest room.

You're nervous, and you see Mikan, Momo, and Nana giving you jealous looks as they take you with them. You blush intensely and don't know what to say, especially when Lala, Risa, and Mio hug you and start kissing you. Risa and Mio help you take off your blouse, noticing you're not wearing a bra.

Risa laughs with amusement as she looks at you and squeezes your breasts. "You naughty girl, Riko! As always, huh?!" she says mischievously, seeing you moan with pleasure and close your eyes. "No need to be embarrassed! We'll help you, the three of us, as always!" Mio says mischievously as she pulls down your pants. "Besides! Now, you'll help me too, right?!" she says playfully.

You, who were enjoying Lala and Mio's touch, open your eyes and look at Ria, puzzled. You're about to say something when you see her pull down her skirt, revealing her panties, which show a considerable bulge. "Holy shit! What the hell?!" you exclaim, unable to stop yourself, with a gesture of immense surprise.

Lala and Mio, beside you, look at you and laugh at your reaction. Lala pulls you into a kiss, while Mio helps Ria pull down your thong. Together, they begin to caress your cock, which you quickly give in to. All the while, you continue kissing Lala, enjoying the sensation.

A while later, you had Lala on all fours, naked, while you passionately thrust into her, you too naked. Meanwhile, Risa, behind you, was forcefully thrusting into your ass, making you moan like crazy as you thrust into Lala, who was also moaning as she ate Mio's pussy.

Risa, meanwhile, was pumping your ass hard, gripping your hips and moaning. "Look how much you're enjoying this, Riko! It was just what you needed, to relax a little!" she said enthusiastically, without stopping her thrusts. "Come on, Riko, fill Lala's pussy and get her to join us!" she said as she spanked your buttocks.

You nodded, focused on fucking Lala, and soon felt yourself about to come, so you sped up your thrusts. "I'm going to come, Lala, get ready!" you said with all your might, noticing that you couldn't hold back anymore and, finally, feeling your orgasm approaching.

You shudder and let out a very feminine moan as you fill Lala's sweet, fertile cunt with your semen, while Risa moans and you notice, shortly after, that she fills your ass with her semen, finishing soon after Lala, moaning and coming, just like Mio.

You keep penetrating Lala with your cock, enjoying the sensation, until you finally sigh and, as you feel Risa pull out of your ass, you also pull out of Lala, smiling and enjoying the feeling. Once recovered, you spank Lala. "Good girl, Lala! That was wonderful!" you say happily, watching her shudder and let out a moan.

You can hear Risa laughing as you pull away from Lala and look at her, who winks at you. "See how wonderful, Riko? Now... Where are you going?!" she starts asking, watching you gather your clothes and head for the door.

You don't answer her, because you hear Lala moan again and open the door. Even though you had enjoyed it, you needed answers now, so you run upstairs to your room, go inside, and get dressed again. You knew the person you had to talk to was Mikan.

After getting dressed, you head to your sister's room, whose door is open. You glance inside and see that no one is there. You're disappointed, but then you remember what you discovered yesterday. After frowning, you go to the Deviluke sisters' rooms, guessing where Mikan might be.

Once there, you see that the room is silent. First, you look at Nana's door and see that it's closed. Then you look at Momo's, which is ajar, so you walk toward it with determination. As you approach, you hear noises inside and soft moans.

Without hesitation, you open the door and look inside, but you quickly stop and look around, confused.
