Not my first time hearing this, it depends on author but tbh in most cases omega/alpha relatives are mostly resistant towards each other pheromones, but not immune, but it really depends on the authors xf
Yeah sadly most ive read even their brother/father alpha can be affected by the omega's pheromones :(((
truth be told according to the rules of most of these authors it would totally happen just that it never gets addressed I only know one where it's specifies sibling affects but idk but I've actually read a ton of omega verse
The part with the alpha brother is so sick lmao or am I reading this wrong ? Even blood related siblings will lose control over their omega brothers ?? Inbreeding much ?? This is my first (or what I can remember) where a family member of diff gender is affected by the hormones released.
