if the player gets into a point where they are completly immobile and incapable of winning maybe theres a room the player is put in where its the breeding room where the girls randomly walk into to sate their desires but one of the girls has a random chance to walk in and pick you up and bring you to the medical room which is the room where they aint allowed to touch us in sorta a safe room that only unlocks when the player is in a critical state or with a perma injury like busted nuts which causes high pain and causes a random stagger or fall
you head to the medical room and the doctor android could heal even the worse of your injurys they really smart :)
also the friendship thing id maybe suggest adding a kindness thing to the game where if your kind to the girls they will try to ask for sex over just attacking you and knocking you out but this bar could take awhile to build up
you do tasks for the girls hide untill they start and then climb into bed with one to help them with their issues this could increase their love for us
maybe a few of these are to repair them or recharge them or feed them in the case of chica and every time you help them they become nicer and sweater to us
instead of them just hating us perma they could start hating us and abusing us like the robots they are but slowly grow closer to us as we help them out and this would make it sorta a balancing act for them
they either sate their horniness or help us out maybe their horniness makes them aggressive and abusive but they could have a sweat side where if they see us and aint really lustfull they could help us out and bring us to the medical room or to chica where she could feed us to loss 1 negitive trait
