Technically you can avoid sending the girls to the bordello but it really hard to get money unless you cheat and you will be missing out on content.
even if we dont sent them,the main story is still like that,Lex look inferior in here and possibility the girls addict to other bastard dick instead of Lex is high..The Lex i know he always know the possibilities in the future,the strip club that Roulette manage already okay in my opinion,they entertain the patreon,but the meta bordello?i dunno,just like Lex said,the girls can only feel pleasure by others not by themselve because that is what the mind control do...instead of following Lex order and entertain him,they might not satisfied when Lex have fun with them..they might start complain some bastard dick in bordello much better than himself..and i can already see Lex reaction if they say something like that..his ego will be insulted and there is nothing he can do if that happen,the current situation now is much better,they been mind control and dont really have emotion and memories when they get gangbang or having sex in bordello,which is mean,they only remember only Lex fuck them and can only been satisfied by Lex,if Lex upgraded the device to maximum and they willingly go?he will be a cuck in his own harem..so,im just hoping the upgraded maximum device only make them obedient to Lex and they become an army for him instead of they just willingly go to meta bordello and make Lex look like a cuck later...You know?if the superheroin do some illegal stuff,then Lex reward her with brutal sex or some wish for her been granted by him..which is mean,they become slave to Lex and can only satisfied with Lex alone..
