That happens only if you want, like the rape of the baroness daughter, that orc was bitching about you not being a orc and made a stupid story about a curse, so the other orc tell that to not have a curse that you need to fuck her (gangbang) but that scene only happen if you don't believe that she is lying.
Yea, I finished playing the game by now and noticed the scenes are optional.
although the rape of the baroness daughter can end up unexpected unavoidable.
first time I played through it I went
> I am here to join you
instead of
> I am here to rescue the girl
The chief then said he will go rape the girl.
I was then given the choices of
> fight him
> persuade him not to
If you choose persuade it just goes "persuade fails" at which point you cannot stop it anymore, if you chase after him you can only watch and not interfere anymore.
I would have expected a failure to persuade to give you the option to fight him.
So, I reloaded. went
> I am here to rescue her
> fight chief
> rescued abby (noble girl)
> came back later and THEN joined the orcs
