While its an ugly truth its the the truth all the same. The genre/fetish of NTR is a niche crowd just like futa/trans, some people have vanilla taste and hate when the game makes it the only option for said game its not saying he hates people that like ntr or anything.
Well it's fine this game offers variety but something as simple as thinking a civilised confrontation with your spell master would be reasonable and give you a choice rather then go the way it did? (Honestly I wouldn't have minded if she would seduce the couple rather then mind control but the fact she does and you have no means to resist even after I broke through the head librarians spell makes my frustrated)
