honestly i think it could be cool if you had all the enemys being breeders be they a female into a futa or a male
if you get beaten by a enemy maybe their could be spots in the enviroment where they use our girl and instead of a game over maybe we have lives and our girl slowly gets corrupted and becomes lust broken lossing to many times eventually gets us a screen of being the devils play thing as he sits on his throne and we bounce on his giant ass cock as our belly is nice and stuffed by him
