Ninokuru Soga had a wonderul life. He was in a relationship with his girlfried Hirasaka Mei. He was happy.
It all changed when one day he received a video file.
When he played it, he saw his girlfriend together with Kazamaki Matsuri.
"Hey there Soga-kun." He smirked towards the camera. "Today I will fuck your girlfriend right here on cam. Hehe."
What he said, happened. Shortly after some more talking, he fucked Mei on the bed.
"Tell us Mei. Who feels better? Me or your boyfriend?"
Mei moaned as Kazamakis penis went inside her again and again. "You! You feel better Kazamaki-san!"
The video ended with Kazamaki finishing inside Mei.

Soga looked at the screen and decided to take his revenge!
He waited for Kazamaki in a back alley and knocked him out from behind. Afterwards he took him to his own apartment.
"Huh?" Kazamaki woke up, lying on the floor.
"What hap-! My voice?" He looked down on himself, only to see boobs. "What?"
"Hahaha. Are you awake Matsuri-chan?"
Kazamaki looked up, only to see Soga standing in front of him, holding a package with pills.
"I used these genderswap pill to tranform you into a girl. You stole my girlfriend, now I will turn you into a whore."

曽我二ノ来（そが にのくる）は素晴らしい人生を送っていた。恋人の平坂芽衣（ひらさか めい）と交際し、幸せな日々だった。
しかし、ある日届いた一本の動画ファイルが、すべてを変えてしまった。
再生してみると、そこには恋人の姿と、風巻祭里（かざまき まつり）の姿が映っていた。
「よお、曽我くん」彼はカメラに向かってニヤリと笑った。「今日は君の彼女を、このカメラの前で犯してやるよ。へへっ」
言葉通り、それは実行された。少し言葉を交わした後、彼はベッドの上で芽衣を犯し始めた。
「言ってみろよ、芽衣。どっちが気持ちいい？ 俺か、それとも彼氏か？」
風巻のペニスが何度も出し入れされるたび、芽衣は喘ぎ声を上げた。「あなた……！ あなたの方が気持ちいいよ、風巻さん！」
動画は、風巻が芽衣の体内で射精して終わった。

画面を見つめた曽我は、復讐を決意した！
彼は路地裏で風巻を待ち伏せし、背後から殴って気絶させた。そして、彼を自分のアパートへと連れ込んだ。
「ん……？」風巻は床の上で目を覚ました。
「何が……！ 俺の声が？」自分の体を見下ろすと、そこには大きな胸があった。「はあ？」
「あはは。目が覚めたか、祭里（まつり）ちゃん」
風巻が見上げると、目の前には錠剤の入ったパッケージを手にした曽我が立っていた。
「その性転換薬を使って、お前を女に変えてやったんだ。俺の彼女を奪った報いだ。今度は、お前を尻軽女にしてやるよ」

Rather poorly done, especially for an AI generated one, the artist couldn't even keep the character in the same clothes from one scene to the next and half a ton of the same dumb scene without any show that anything new was happening... Except that the background that should have been the same changed each time... um dude walls and windows and doors shouldn't pop in and out of existing in the same scene... Like a 2/10...
