Huge tits layer is my conceived meat Onaho! ~ To Chin flattery layer by cuckold copulation her of friends!～

In a small doujin circle of 3 members, the main character who is sandwiched between two men and women who are conscious of each other, Yuto of the okute otaku and Airi of the sober female-style but arousing cosplayers, had been living a uncomfortable day.

At such a certain time, I witness Airi stealing the radical erotic doujinshi that the hero had hidden with a bright red face.
I was like, "Why don't you go through the same thing?" and I was like, "Why don't you go through the same thing?"The hero who approached, pushes down Airi as it is!
Intense Caress, Creampie sex!
I let Airi fall immediately in one shot, and succeeded in making her swear loyalty as a convenient cosplay Onaho for her own use!

In this way, the otaku life of the dream to roll up the transformation cosplay play using Airi of the erotic slut body was started!

所属3人の小さな同人サークルで、奥手オタクの優斗と、地味女風だがそそるコスプレイヤーの愛莉という意識し合っている男女ふたりに挟まれた主人公は、居心地の悪い日々を送っていた。

そんなあるとき、主人公が隠し持っていた過激なエロ同人誌を愛莉が真っ赤な顔で盗み読みしているところを目撃する。
やけくそ気味で「それと同じこと経験してみない？」と迫った主人公は、そのまま愛莉を押し倒す！
激しい愛撫、中出しエッチ！
一発で愛莉を即堕ちさせ、彼女を自分専用の都合いいコスプレオナホとして忠誠を誓わせることに成功した！

こうして、エロ女体の愛莉を使って変態コスプレプレイをしまくる、夢のオタク生活が始まるのだった！
