About This Game

One day, I lost something very dear to me.
A collection of cherished portraits, photographed at various cosplay conventions, guided by my trusty libido―in an unfortunate accident, the digital camera with all that data goes kaput.
Witnessing the tragedy, sisters Yua Yamakake and Sana Yamakake say to console me as I wail in sorrow...

“...How about you take some cosplay photos of us?”

I accept. I readily accept.
These sisters, with full-bodied figures you only see in porn, are offering to become my very own cosplay models!
Amassing every skill I honed as a dressmaking student and a doll costume designer by passion, I make it my duty to create cosplay outfits for the two.

And as I begin to pick up speed, I get another lucky break.
In a peculiar turn of events, I’m given a ticket to Costalia, an island resort for all things cosplay.
There, I’m certain I’ll snap the greatest photo there ever is.
...What I don’t know is that what awaits me on the island far exceeds my expectations.

“What should we cosplay as today?” “Want to do some sexy roleplay?”

The Yamakake Sisters―aka the Tororo Sisters―whisper such words to me.
These photos of my very own cosplay models are so sensual and elaborate. I can never show them to anyone else.
Am I safe to indulge myself in these shoots...?

This version includes the APPEND story and data patch, with three additional animated sex scenes with new outfits and impregnation!
