Elthara keeps geting pregnant from the PC (male) instead Arona or Quintillus in the Wayford when doing threesomes

[Papum]

When having sex with Elthara at the Wayford together with Arona or Quintillus (as an male character) she alway's gets pregnant from the PC and never the others.
I though that doing those thresome specific scenes where the ones that would get her pregnant from them?

It depends on the scene. Sub Arona never fucks El vaginally (she gets BJ or does anal and then she gets fucked not El) - and that align with how Sub Arona impregnates others (only allowed explicity by PC). With Dom Arona I never had problems.

Similar case with Quin - In first scene he never actually engages with El vaginaly. In swap fuck he should be able to impregnate her.

TLDR: It looks that it works like intented for male PC
