Depends. R u asking about true NTR or broud NTR? As of this update all sharing/cuck scenes are completly optional. But heres the list that people bitch about the most:
-Mia= u r cucked by a Werewolf but Mia thinks its u. Completly optional (if u go "No Cuck" u lose access to the Werewolf Hunt sidequest)
-Ziva= u can let the giant, Grug, f*** her or u can fight him. Later theres 3some with Ziva & Grug but now its optional.
-Shakala= Goblins gangbang her on wedding. Now u can refuse this.
Others that r not NTR but still bug peopel:
-Beth "milks" Samson the horse for his seed so she can sell it.
-Victoria was married to the mayor & cheating with MC.
-Gwynneth is a prostitute & MC has pay her ti distract men during 2 quests.
-Hilde is married to the clan Chief of the giants.
-MC is cucking Thomas with his with Jenny.
-Those who r into Maghda (ogress) hate Dolf as well lol.
Molestation Scenes:
-Mia is about to be molested by 2 goblins. U can watch or save here.
-Caleah is being r***** by an orc. U can watch the whole scene or intervene.
Hope this helps
