Here is a quick guide on how to get most of the scenes in the littlest amount of time, and technically gives you a "completed" save where you are undefeated and still a virgin, and unlock everything in the gallery.
Just beware for people who are into vanilla romance sex. Unfortunately this game has essentially no consensual romance content. All the scenes involve essentially getting yourself and your main companion raped. Or whoring yourself in 2 prostitution scenes, letting a generic male soldier use you by running a train on you as a unpaid camp whore, or whoring yourself out by seducing your generic male companion / co-leader which the game constantly state you're not in a romantic relationship with and only do so to reduce his salary.
1. In the intro chose to escort the girl to Adventure town to get an easy +20 reputation and some money.
2. Go into the guild menu and accept a few easy escort / transport quests for easy reputation.
3. Once you get 50 reputation. Save your game in slot 1.
4. Go into town invite a female character (assassin, female militia, nun) to be part of your party. Head straight into the Thieves Cave, and try to head to the second floor so you encounter more enemies in a battle so they defeat you quicker. If you get attacked on the first floor you can chose to kill them or just let them defeat you. Essentially just keep whichever character you're controlling out of combat, so that enemies can knock out your companion without your companion killing too many of them. Then just run back and forth in front of the enemies so they can knock you out. Congratulations you have gotten yourself and your female companion raped by bandits and unlocked the scene.
5. Reload yourself save rinse and repeat step 4 two more times with the other type of generic female companions.
6. Do the same thing as step 4 and 5, except instead of going to the Thieves Cave, go to the Iron Wall Mountain. That way you get yourself and your companion raped by orcs.
7. Reload your save from step 3 (slot 1), go to Slave City and chose NOT to buy Grace for 2000 gold.
8. Go into the inn and stay for the rest of the season.
9. Make a second save in slot 2.
10. Go to the arena and you should get the option to duel the "champion". Beat Grace.
11. Chose to sell her.
12. Then reload your save in step 9 (slot 2). Beat her again, then free her, she will join you as a companion.
13. Save your game again in slot 2.
14. Do steps 4-6 again as in run into Thieves Cave and Iron Wall Mountain get yourself raped by bandits and orcs with Grace as your companion, except this time load your save from step 13 (slot 2) in between.
15. Reload your save from step 13 (slot 2) and keep Grace as your companion
16. Then go into Andora and talk to Platina to activate her quest. Then hire about 20 mercenaries in the town, you can just open and close the town to refresh the recruitment pool. You should in theory have more than enough money (400-600+ gold) from doing 3 or so transport / escort quests earlier.
17. Save your game in slot 3.
18. Go into the Thieves Cave. Head straight for the ladder on the first floor to activate Platina's event. Then leave her group to their fate. To unlock the defeat scene. Press retreat. To exit the dungeon. Reload your save from step 17 (slot 3).
19. Go into the Thieves Cave again. Optionally then proceed to explore the first floor to to help level up your character and Grace, or you can just skip straight ahead the ladder to just clear the second floor without failing to save Platina this time.
20. In theory you should be high enough level now to keep following Platina's questline, by just going back to Andora, activate her second quest that takes you to the Iron Mountain Hills, and third quest at Fortress City.
21. Save your game in slot 3.
22. Dismiss your Grace, and dismiss all your mercenaries. Then go hire Platina. If you don't have enough reputation then go do a few quick transport, escort quests to gather 50 Reputation.
23. Save your game in Slot 2
24. Do steps 4 and 6 again. You know the part about going into the Thieves Den and Iron Wall Mountains and getting yourself intentionally raped by bandits and orcs, while reloading your save from step 23 (slot 2).
25. Reload your save from step 21 (slot 3).
26. Go to Adventure Town to encounter Nia the assassin, defeat her. Go to the Sand Ruins afterwards to encounter her a second time. Team up with her. Do her quest and don't kill her!
27. Save your game in slot 3.
28. Dismiss your companion and mercenaries. Head to Slave City, and intentionally lose the fight to save Nia.
29. Reload your save from step 27 (slot 3). Head to Slave City and save Nia this time without throwing the fight.
30. Save your game in slot 3 again.
31. Dismiss your companions mercenaries again. Hire Nia as your companion. If not enough reputation then do a few escort or transport quests.
32. Then save in Slot 2.
33. You should know the drill at this point. Repeat step 4 and 6 again, except reload your save from step 32 (slot 2). Go intentionally lose a fight in Thieves Cave and Iron Wall Mountain to get yourself and Nia raped by bandits and orcs.
34. Reload your save from step 30 (slot 3). Go to Flower City, and do Merdrin's questline so you can recruit her.
35. Save your game in slot 3.
36. Dismiss your companions mercenaries again. Hire Merdrin as your companion. If not enough reputation then do a few escort or transport quests.

39. Reload your save from step 37 (slot 2).
40. Next we're going to do the Male partner scene. You should of have a ton of cash at this point. So dismiss Merdrin. Go invite any male mercenary (male militia, fighter, gladiator) to by your partner. As always if you don't have enough reputation, go do a few quick and easy transport or escort quests.
41. Stay the season at an inn. Then talk to your male companion to raise his trust up by 1. Then rinse and repeat until you are at max stars, which should be about 5 times.
42. Save your game in slot 2 again.
43. Note very important, once you get max stars, stay the season at the inn again, this time DO NOT TALK to the male companion. Proceed to immediately chose the sex option with the companion, cause if you talk to the companion it prevents you from having sex with your male partner for the rest of the season, though not to worry, if you mess up you can just stay the season again, or reload the save from step 42 (slot 2). The scene is bugged when you unlock it where it instantly close once you get in game. But you can see it in the gallery.
44. Reload your save from step 42 (slot 2).
45. To get the second orc scene, you need to get raped in the open map. Dismiss your male companion. Go into the guild and get yourself a high ranked escort quest or bandit suppression quest. You don't get random encounters on the open map unless you have an escort quest or bandit suppression quest.
46. Save your game in slot 2 again.
47. Run around near nameless Wilderness until a "bandit attack" happens, which sometimes actual bandits and other times its a bunch of orcs. If its a bunch of orcs then lose on purpose. If its bunch of bandits beat them, and keep wandering around or reload the save in step 44 (slot 2).
48. Load your save from step 35 (slot 3).
49a. To get the mercenaries having sex with you scene. Just go repeatedly stay at an inn for the season with your army (assuming that it has a couple of males) until the event fires.
49b. For the infamy scene, which is super easy just go into a town and attack / kidnap the townspeople 10 times or you can do assassination guild mission and chose "kind" targets.
49c. If you haven't gotten 20,000 gold scene yet, then just go do a few quests or farm any dungeon with your army.
50. At this point you should of unlocked every scene in the game. And in theory you should have two good saves, slot 1 and slot 3, where you can chose to start to play the game normally as a virgin since you never prostituted yourself or been raped. Slot 1 should be at the very beginning of the game. Slot 3 where you have essentially unlocked all the named female companions and can continue sandboxing to your heart's content.
