【The Delicious Side of Bird】The Book of Black Usa Becoming Female Tentacle-sama

This is an original tentacle book.
The story is about a girl who is caught by tentacles, trained by her twin sister who was corrupted first, and tentacles, and made to wear tentacle clothes.
I’ve also included other elements that I’m personally interested in, such as facehuggers and begging on your knees.

I recommend it for tentacle lovers.
