　寝たふりをしながら意識を自身の身体に集中させる。まずは自分の現在の身体の状態を理解する、頭から顔、胸、お腹、股間、そしてつま先と順番に注意を払っていき、自身が男性であることを強く意識する。次に自分が成りたい姿をイメージする。立体感のある縦巻き、顔はやっぱり美少女アイドルのような愛くるしい顔立ち、主張しすぎない胸、魅力的なくびれ、そして、ぷっくりとした割れ目…。

　成りたい姿のイメージが固まると同時に自身の身体に変化が起こる。ゆっくりと、だが確実に、男の身体から思い描いていた女性の身体へと変わっていく。ごくりと彼が生唾を飲み込む音が聞こえる。半分くらいまで変身が進んだところで、彼は堪えかねた様子で僕に話しかけてきた。

「お、おい！　起きろ！　また女体化が進んでいるぞ…その、今日も俺が手伝ってやろうか？」

「ん、むにゃむにゃ…あ、おはよう。　……うん、今日もお願い♡」

　僕が起きたふりをして彼に答えるや否や、ルームメイトは僕の腰を持ち上げ、出来たてのおまんこに腫れあがったペニスを挿入する。

「ふあっ…、君のおちんちん、すっごいガッチガチ。　ふふ、そんなに僕の身体に興奮したの？」

「ばっ、馬鹿言うな！　女体化を抑えるのに俺の精液が必要なんだろ…。　お前が女の姿のままだと学校の授業に参加できないから仕方なく手伝ってやってるだけなんだからな！」

「…んっ、あんっ、ふふっ、うんっ、そうだねっ！♡」

　彼には、僕が自由自在に変身できる種族であることは内緒にしている。もちろん精液で男に戻る設定も真っ赤な嘘だ。彼には悪いが、男子寮で生活する身で様々な女の子の姿に変身してセックスを楽しむには、"朝起きたら女の子になってしまう特殊な体質で、元に戻るには精液が必要"という"設定"が何かと都合が良いのだ。お互いに。

「僕も男に戻れるように頑張るね！　すぅ……、んっ、あんっ♡ あ、あぁっ♡　わたくしのとろとろのおまんこの中は気持ちいいですかぁ？　ふふっ、遠慮しなくていいんですよ♡　あっ♡あっ♡　そんな、激しくッ…！　あんっ、あんっ♡　ええ、もちろんです。このままわたくしのおまんこに無責任中出しを決めてください♡」

　僕は彼の腰の上にまたがると、前後に激しく腰を振って大げさに演技をして見せる。彼に気持ち良くなってもらうため、姿や服装も飽きさせないように少しずつ成りたい姿のイメージに変化をさせて……。

　こうして僕たちは起床時間まで、毎日、毎日濃厚なセックスを楽しむのだった。

終わり。

(English)

Every morning, my roommate wakes me up from my sleep. Well, I am woken up by my roommate, but she just rips off my futon and blankets. At this point, he never calls out to me. He just watches me sleeping, breathing hard and rubbing his own dick.

Oh dear, he's been so lively this morning...I blurted out in my mind...

Well, I am the reason why my roommate is like this. Okay, I guess I'll live up to his expectations.

While pretending to be asleep, I focused my attention on my own body. First, I understand my current physical condition. I pay attention to my head, face, chest, stomach, groin, and toes, in that order, and become very conscious of the fact that I am a man. Next, imagine how you would like to be. A three-dimensional vertical curl, a lovely face like a beautiful idol girl, a breast that is not too assertive, an attractive neckline, and a plump cleft .......

As soon as the image of what I wanted to become became solidified, my body began to change. Slowly but surely, my male body is transformed into the female body I had envisioned. I hear him gulp down a mouthful of saliva. When I am about halfway through my transformation, he looks as if he can't stand it any longer and speaks to me.

"Hey! Wake up! You're getting feminized again... well, how about I help you become a man again today?"

"Nn, mmmm...oh, good morning. ......Yes, please. Please help me today."

As soon as I responded, my roommate lifted my hips and inserted his penis into my cunt.

"Oh...wow, your cock is so stiff. Hmmm, are you that turned on by my body?"

"Don't be silly, you need my semen to suppress your feminization...! I can't participate in class if I'm in female form, so I'm only helping you out because I have no choice!"

"Hmmm, yes, you're right!"

I don't tell him that I am of a species that can transform at will. Of course, the whole "semen turns me back into a man" thing is also a complete lie. I'm sorry to tell him this, but it's a convenient way for me to enjoy sex while living in a boys' dormitory, where I can transform into a variety of female forms.

"I'll try my best to become a man again, too! Sooo..., ah♡♡ Ah, ah♡ Does it feel good to be inside of my soft pussy? You don't have to be shy ♡ ah♡ ah♡ that's so hard......! Please fuck my pussy irresponsibly."

Straddling his waist, I shake my hips back and forth violently and try to act exaggerated. In order to make him feel good, I would gradually change my appearance and clothes into the image of what I wanted to be so that he would not get bored....

Thus we enjoyed intense sex every day, day after day, until our waking hours.

The end.
