While walking towards the Kotegawa's residence, Yui had begun to fill me in on her family. Telling me that she only lives with her older brother Yuu Kotegawa, as both of their parents seem to always be gone for work matters. And in return I told her about my family, which she already knew mostly except for the bit about my parents.

Though as we had continued walking I had begun to realize that my shoulders were starting to feel sore all of a sudden. As he had turned towards me Rito(Y) had noticed the uncomfortable look on my face, and had asked "is something bothering you Yuki-kun?" wanting to know if I was alright.

Knowing that he knew this body better than I did I said to Rito(Y) "it is not much Yui it is just that my shoulders feel really sore right now." is what I told him. Only to see my former face to blush a very deep red color. Not knowing if i said the wrong I quickly said "I am sorry Yui if I said or did something shameless again." apologizing to Rito(Y)

Only for him to say back to me "don't worry about it Rito you did nothing wrong, its just that what you said was embarrassing for me." as he answered me. Though he quickly spoke again and said "ever since they started growing since I was little, I have always been self conscious about the size of my breasts and that is why your shoulders are sore since they are a handful to carry about while walking." is what he had told me.

Finally after walking for awhile we finally arrived to the Kotegawa's family home, only to see a note taped to the front door. After taking the note and entering the house, we shut the door behind us and sat down on the couch, as Rito(Y) read the note. Once he was finished he said that it was from Yuu, yelling Yui that he was called into work and won't be off until late at night. And that there was a mess in the kitchen for her to clean.

After that we got off the couch, and went to the kitchen to see not only scraps of food out but also many dishes were dirty as well. Deciding to handle the dishes first we got them done in no time at all. Next we were cleaning up the leftover food, when Yui's pet cat had came in the kitchen. And saw Momo on her knees cleaning something, only for the cat to be distracted by Momo's tail, and it leaped at it and started to play with it. Only for Momo to start getting really aroused. Though once we had swa what was happening Rito(Y) went to get the cat, only to step on a bottle of Mayonnaise which squirted all over me and caused me to fall down.

Once I had let out a surprised yelp did Momo and Rito(Y) turn to look at me, only to see me with not only mayo all over me but my legs spread as well showing off the panties i was wearing. Seeing me in such a state Rito(Y) had said "I am sorry Yuki-kun are you alright?" wanting to know if I was okay. Though seeing how I was smeared all over, did Momo offer up a solution.

In which she said "Kotegawa-san since Rito-kun is messy may he use your shower to get clean?" which caused both Rito(Y) and I to blush atomic red. Quickly stammering out a response I said "but I am in Kotegawa-san's body I can't take a shower like this?" with Rito(Y) agreeing with me. Only for Momo to state that either I get cleaned up, or stay as I was. Knowing that there was no way out of this both Yui and I made our way to the bathroom.

Once we had finally entered the restroom, Rito(Y) had told me to close my eyes while he would take off my clothes. After stripping me of the school uniform, I was left in nothing but the bra and panties that Yui had worn today. Though Rito(Y) told me to keep my eyes closed as he removed the bra, but when it came to the panties he asked if I could do it myself. As I had nodded in agreement I bent over and proceeded to remove the panties. Although while I was bent over I nearly lost my balance due to the weight of my new breasts pulling me downwards.

After all clothing was removed from me both Rito(Y) and I had stepped into the shower. Once he had started the shower and began washing me, though I had kept my eyes closed for both of our sakes. After one long and awkward shower later we had exited the shower, and Rito(Y) had grabbed a towel to dry me off. Once that was done he had left to get me some clothes to wear, which were a pair of white panties and her pajama clothes.

Noticing that there was no bra I turned to Rito(Y) had asked him "you are not going to have me wear a bra?" as I questioned him. After a moment had passed he stated to me since I was not in public I did not need to wear one for now, and that wearing one for bed was not a good idea. Once that was done we had went back to the living room to find Momo looking over maru-maru-change-kun once again.

Once she had looked up and saw us she gave a defeated sigh and told us "sorry you two I still could not figure this thing out, I think it is best if we call in Lala now." to which we agreed knowing that this was serious. After we had made the call to Lala she had immediately came over to Yui's house.

Though as soon as she had came over she immediately asked "so you three what seems to be the problem you have?" as she questioned us. Gulping nervously we had told about the situation we were facing, and we had apologized from keeping it from her. Though once we were done explaining Lala did not look mad as she said "thank you guys for trying to protect my feelings, but you still should have told, but now let's see if we can not get you fixed." giving us hope that she could fix this.

Although after we had handed the device in question as she looked over it, she immediately paled. Though after a few moments had passed she had started to speak "I am so sorry you two, but unfortunately I can't fix you, for you see when I made this version somehow the swap became permanent since I tested it on a pair of animals and I was unable to switch them back to normal." as she had finished her explanation, which only served to disappoint us greatly.

Turning to Rito(Y) I started to speak and say "I am so sorry I got you involved in this mess Kotegawa_san, since now you've lost your body and life to me." wanting him to know how sorry I was for the situation. Though it came as a great surprise that he did not look that angry about what has happened.

Finally he put a hand on my shoulder and said to me "it is not your fault alone Rito I am also to blame, the only thing we can do now is help each other live our new lives to the fullest." which relieved me. And as well as I had agreed to help him live his new life, though before that we had both turned to Lala and said to her "thank you for your help Lala and don't worry we do not blame you for any of this at all." putting said girl at ease.

Though as it was getting very late at night, Rito(Y) had taken the liberty to set out my clothing for school tomorrow. And after I had thanked him, both him, Lala, and Momo had left back to my former residence. Afterwards I had made myself some dinner, and had immediately went to bed after this long and tiring day, only for tomorrow to begin my new life as Yui Kotegawa. ,
