About this game
"The Bound Crystal" is my first and only bondage game for PC, starring the real beautiful model Khrystal!
STORY:
Miss Khrystal was entering the parking lot of her workplace when she was approached by someone asking for information. While she was talking to this person, someone came up behind her and put a cloth over her face. After that, she doesn't remember anything. Upon waking, she realized she was in a strange place just in her underwear, tied up and gagged.
The truth is, Khrystal was taken to "Phoenix Island", a place where a group calling themselves "Glitches" are conducting a study on human behavior under pressure. They told her that on this island, there's a yacht that works by activating three crystals scattered around the island. Khrystal needs to find and activate them for the yacht to work and for her to escape.
Each crystal is worth $500,000, and Khrystal can keep them if she manages to escape, but it won't be easy.
Who are these people and why are they conducting this crazy study?
----
INFO:
TBC was made to be a quick, simple, but also somewhat challenging game, so there are no maps or much help. Remember, you just got kidnapped and you're trying to escape an island you don't know.
This is a 18+ game, but there's no explicit sexual content, this game shows bondage as an art!
6 skins avaiable to play and more to come!
1 secret achievement.
3 types of gags.
Bondage Mode already avaiable!
This is just a fantasy story and no, we don't condone misogyny nor the idea of people, especially woman, being humiliated or restrained against their will.
You can play with a controller but you need a mouse\keyboard to use the menus, that will be changed in a future update.
Everything that's happening is completely consensual even in scenes that appear otherwise.
All characters portrayed are 21 years or older.
