Our protagonist gets transmigrated to a free-use world where sex can be bartered for. It's a world with all kinds of magical beings, from angels to demons and everything in between. Protagonist will have to work hard to keep his little life, when he finds himself in the middle of a battle among the forces of good and evil.
All types of kinks will be explored in this story, so you have been warned.
Also, it is NOT a vanilla story. There will be no cheating involved but, some of the chapters can be rather intense.
*It can be a hard read till 100 chapters but it's quality will improve afterwards, along with some actual development of the plot.*
