What a stupid Genie. That wasnt even the wish. The wish was completely different and not even Genie - even if she was stupid as a brick - could make it this fucking terrible. What a bunch of bullshit.
All I can say about the plot is that the first genie is secretly working for the guy in grey shirt to eliminate his two rivals by turning them into his harems, and the first victim was turned into another genie and initially took the form of a harem dancer then into a middle-aged seductress, turning the second victim into concubine belly dancer.
Why do all that convoluted stuff, because porn logic, that's why.
