I think this is it
As i mentioned before, it's a series. This one is about the hpnotism and he still fights it.
The one that the OP asks is about another male lead. It's the "my little brother" series, not the hyno rape series.

I read the prequal and it's about this boy get lure out and gang rape by a group of strangers. They enslave him and lock him in a house where he got rape non stop. They even film him, sell him to some old geezers, tie him in public rest room and let anybody fuck him. Moreover they send all the videos to his older brother.
When the boynreturn home, they force his older brother to rape him. The older brother willingly do it and the boy become eveyone's toilet.
