Thank you again for your suggestions! This was a lot to take in so we’ll go in order:
1 and 2, I’m not sold on the cock vore idea, but perhaps more of a tail vore like Cell from DBZ. Following that path, I think absorption of creatures and NPCs is very likely, the player would just need to work on his Incubus rather “evil” side to unlock such behaviour. The tail itself could be acquired from any and all creature he meets, it would be absorbed by the spell taught by Byzeff and manifest itself whenever needed. I’m not opposed to the idea of making an NPC or creature being converted into an organ like suggested in 5 where you could tap into a their attributes at will. This would be essentially an upgrade over Byzeff’s spell that can only randomly absorb traits, here you could even take the full appearance or only isolate like you said, the trait desired while remaining human looking.
3 is pretty much a must.
4 I’m not fond of the correlation between Ass and Sewers/Swamp. Hunger wouldn’t be an existing concept in those sexual driven dungeons, so food isn’t really food as much as it is a mean to absorb various effects.
5 I revolve more around this idea of milking the captives for their abilities like the player does when swallowing Rohan’s soul. Nothing would really be permanent so it would require a lot of work to keep the host stable … like not going against their principles.
6, well surprisingly I’m not against sounding but dick fucking isn’t really working for me if it’s just two regular dicks. I think it’s due to the nature of a cock being rather thick than long compared to the urethra. My counter idea would be to use more slender appendages like tendrils that could dive deeper into it and stretching only reasonable the tube.
7, so slimes would essentially just parasite the entire system until they reach maturity. Toads are usually already in symbiotic relationship with them and will cum slime coated cum eggs to impregnate their partners. That put aside, to join with point 9, in those realms it doesn’t really matter if you hold a womb as your body is vulnerable by concept rather than biology alone. This means the concept of being impregnated is a mean to invade your body and soul with what I call a daemon, an emerging property of the sea of thoughts. Without diving too much into the lore, consider it being a creature of simple concepts bred into your mind, body and soul. Much like hosts within your body, they will influence your decision and sometimes even impose unavoidable restrictions (like the mushrooms in your cell) that will require work to circumvent.
It’s not possible to create new entities within these dungeons, these realms are too restricted to allow growth like in the human world. That is why Incubi trap people into them, although they consider it more being selective with their citizens. The human world is very chaotic and lacks a coherent theme, but that’s why it can create new concepts and new beings.
While you cannot give birth, you may replicate a creature’s body like the slime does in you. It’s not a new consciousness, it’s more like expanding its influence. This is what being impregnated means in Incubus Realms: Being imbued with the influence of other creatures, over your body, mind and/or soul. Sex will therefore have consequences such as: Transformation, used to expand the creature’s body, mind controlled, cursed, or blessed. A side note on the matter, if you’ve read the comic, there is a scene where some creatures go through the victim’s body to rebirth. This process is to ensure they can trick the human realm into thinking it’s a member of its world, since you’re born from a human, technically. This doesn’t last long, and the host may lose all of its humanity after only a few creatures go through.
