i just have to write down a couple of wishes...
the selector at the end of the room is cool and all that. But if we could have a separate room, with cages or holding cells, maybe dependent on their submission level, and then we can go physically and take them out to play.
Maybe some kind of "survival" aspect, where we could give them food and drinks. Be it something they want, like actual food and drinks. Or some other less edible things. So we can either starve them or fatten them up.
regarding the instant access we have to all the current girls. What if we have to interrogate those we already have, or convince them to tell us info about other girls, and when we've collected enough we unlock them. Maybe each girl only knows certain peices of info. so you'd be forced to beat one, but keep another one happy to gain certain info.
Bulging and inflation? Guess variable sizes for both types of dildos is needed, and while we do have a extractor, what about an injector(bigger than that tiny one ofc)
Maybe a treshold for fluid buildup while making them deepthroat. And iv'e noticed a "pee" canister, but i have no idea how to extract it. Tried tickling them while using the fluid collector but nothing was collected.
