Too much input! Abort! Abort!
1) Offhand, I'd probably suggest to have some sort of settings or 'plan' for the night when camping, to set options and convienience for later.
Options like Sleep alone / Sleep with lovers, could be set, in case the player is a monster and doesn't want to snuggle with their waifus and husbandos.
1a) Then a option to 'pitch a tent' (using those words, because of course) in the wild, where it's a temporary status or scene. You can rest, wait, have the sex, get milked, perhaps even have a setting where you are inviting or welcoming company/random encounters. And when you are done, break camp, and move on. Simple and effective. Being attacked or events along those lines would of automatically do this, of course.
2) So long as it isn't super annoying to deal with, you should probably have something like camp supplies as a resource. You could also have something like food, or mix the the idea in with supplies. My line of thinking is this is for travel, exploration, recovery, etc.
The more you are traveling with, the more food or supplies may be required so everybody is rested and healed. Or perhaps well rested is a buff.
For example, traveling with a steed (centaur daughter or otherwise), and several companions would like require more than just exploring the countryside with Annette.
2a) As another potential mutation or "blessing": here is one - Liquid Diet. So long as the player is traveling with a horse or a ally that is particuarly well hung (Meat, Bill, Foxxy...Loksi? A hung elf is amusing change up to the norm) and has the proper flags checked, they can reduce the cost or supplement the need of supplies due to drinking down the heady protein shake.
Unsure how how much of a pain it would be to code, but I could see the PC, Annette, Gobfamily, and probably Percy being able to pick this ability up (since Percy can apparently gain or share the players mutations.)
2b) In similar lines of thinking: "Got Milk?" Now there's another use for lactation, where your allies can reduce their hunger (supply cost) straight from the tap, otherwise known as the PC. Requires big 'ol tiddies and of course, the ability to be milked.
Ded allies of course, don't need fud.
3) I realize the irony in saying this after all that nonsense above, but I think the simpler you keep this (regarding camping), the better off you are. Any extended love or polish to a random area or region should probably just be spent on fixtures that you would like to see grow and prosper in game anyway, such as the farm, the witches residence, two's harpy heights, yada yada.
4) I am in love with the idea that camping near groups or random encounters could result in soldiers, travelers, bee girls, your children, bandits, and of course monsters, dropping by. The pc's rep could certainly be a factor here too. (Heroic, harlot, slaver, villain, etc.)
4a) there's all sorts of little mini encounters you could do with this too. A young pair of newlyweds are traveling and seek the comfort and security of your fire, but as a PC you are of course, sexy as balls, so the option of being their first threesome pops up.
A haughty noble lad shows up, without a guard, making demands and you show them how to have proper respect by bending them over a log. Easy payday for slavers.
A wandering minstrel could manifest, playing a song dedicated to the heroes and legends of the past for their supper.
Some soldiers investigate, keen on collecting a fee, only to back off if the player and company are renown. PC's with whore rep and Gobwife / Annette as a companion, could sense an opportunity for profit.
4b) I am also now sketching a scene or two with Gobwife and GobPC servicing several humans, for no reason whatsoever, and is completely unrelated.
5) Heck, since you are spilling the beans, what does Percy use as a weapon when she is brave? Is she just chucking potions or is there a weapon in mind there? She absolutey shouldn't be anywhere near the front.
6) If you are doing the tactic thing, do some combats start as an ambush or surprise, so it's not always front facing?
6a) Thank you for Lamia/naga weapon suggestions. I'm very, very slowly starting to put together character concepts for my own messy rpg style game, as I intend to have the bulk of the companions a bit more unique than four humans off to slay the demon lord, haha. One may or may not be snake type in homage for a certain dev, motivating by example to get off my ass and work on it.
Art is sloooooow.
