I've searched for gold and found it:

Only it wasn't as you described. In fact, after a few attempts I concluded that is impossible to lose at Pale Rock. Though it is definitely possible to make our Bad Dragon lose his chocolate cherry to Zizy's futa-cock.
But firstly, the story.
I had 2 ideas on how you can lose at Pale Rock. The first was to max Infernals while ditching everything and everyone else, then make as many bas choices at the siege as possible. The second was to give Infernals the barest minimum to make them lose morale on Act IV's Conquest.
Both failed.
1. First attempt, led by Zyzerix's Cock Warmer was successful until the culmination of my plan. I've sacrificed everyone to Zizeryx, broken kobolds on repeated attempts to capture Valzira and let demons ravage my entire realm. Then, at Pale Rock, I failed every sensible option (leading to Breaker being killed during he siege), using firebreath instead - including on Adeline, just in case it required total devastation.
9 power for Infernals, 0 for kobbies, every character dead or in Inferno and collapsing prosperity - but no prolapsing dragon assholes.
2. Cursing, I started the second attempt with Zizeryx's Cock Holster (got her name right! Yay!). Was cursing again very soon - turns out, Heloise needs level 4 Charm or level 6 Potency to pass. Since I've got neither and I thought I've got it, I didn't save.
Maybe, my dragon was pegged by angry elves after game over screen, but it was still a failure.
3. Then, finally, came Zizeryx's Cock Holster the 2.0. Some half an hour speedrun of the game that saw me skipping everything except checks to give me Charm 4 - and subsequently, Heloise. Who went on permanent vacation to futa dimension, after which I skipped everything (ate Issa just to get by faster) up until Act IV. During the Conquest I have quickly ran everyone into 0 morale only to realize that you can go to Pale Rock immediately and that doing so does not require morale at all.
Which meant that my second idea was as botched as the first. Yet, it Zizeryx's Cock Holster the 2.0 who lived up to his name.
How, you ask? This time I decided not to skip early Act V and check Zizeryx. In dialogue with whom I quickly found the option to get the futa on male scene with her tonguing and then fucking the Bad Dragon under his tail.
Yes, it is that easy. You just need to empower Infernals, survive until Act V and visit them after your victory. That's how you make your dragon a bottom bitch - or, as Zizeryx poetically put it: "Witness, brother, the ecstasy of the conquered!".
What you require:
Infernals, Heloise, encounter with catgirls, encounter with Maelys, enough stats
What you need to do specifically:
1. During Act I and II farm for Charm 4 or Potency 6. There are plenty of ways so it isn't hard (you will likely have either through natural progression alone), though I wager the Charm 4 is easier to get. If you don't get one of those stats, Heloise will fuck you up.
2. During Act II go for Bastion and talk with catgirls. If you don't do it, you won't be able to get to Heloise.
3. During Act II go to the Forest and either let centaurs fuck Maelys or help her. It is the simplest way to prevent Maelys from killing you at the end of Act III. Two other ways are Kobolds with 2+ morale or having more than one horde (Infernals/Malagar/Proteans do no count here!!!).
4. During Act III revisit Bastion, talk to catgirls and confront Heloise. If you have Charm 4, try to be horny, if Potency 6 - just resist her. Then, take her captive and either tell catgirls about the Mines or don't - if you do, hope you've prepared some traps beforehand.
5. Sacrifice Heloise to the Infernals.
6. Play through the rest of the game as you wish until Act V. Then, hold your first court, which opens the option to pick your generals. Chose Zizeryx, as her what she's doing, pick through the options until option 'Take its hand.' will appear - that's it.
Congrats on subbing your dragochad to futa cock, I guess.
P.S. Infernalized version of Valzira is kinda cool-looking, ngl. And kinda crazy-looking too. I guess being a colossal butt-pain is ingrained in her very nature.
P.P.S. If there is another futa on male scene or that I have really missed the one you've meant, do please correct and enlighten me on the subject. Because this one was good.
