And again, false. You can keep her a Virgin, you just need to manage your Desires.It appears you weren't paying attention to the opening question from the user asking how they can acquire BJ skills when their Karryn is:
'still on Floor 1 (not subjugated), is a virgin [sadist], has 0 orgasms and 0 defeats.'
and they probably intend to keep her a virgin sadist. So no opportunist dick-sneaks into piehole during Goblin sex... If they want her to be undefeated (and frigid) then Guard Battles are the only solution.
BJ Req. is 100 Mouth and 65 Cock. Which you can reduce to 85 Mouth and 50 Cock with Acc. Mascot Phone Strap.
Cunn. Req. is 85 Pussy
Vaginal Sex is 100 Pussy and 85 Cock. Which you can increase to 105 Cock with Acc. Chain Hand.
So don't tell me it is impossible, since I already did it, as long as you keep Pussy under 100 or Cock under 85 (105) she doesn't get fucked.
