Louise and Harriet are tired of always hearing Zayn and Niall complain about how hard it is being male when its obvious they have the harder life being females. "What about boners? You get them for NO reason, they just pop up." "Need I remind you what happens every four week to us? We bleed from our VAGINAS!" "You couldn't last a week as a boy." "Wanna bet? You'd die if you had to deal with half the stuff-" "Yes we do." "What?" "We do wanna bet that we could last longer than you if we were girls and you were boys." A simple bet flip flopped those four teens life forever. There will be tears, laughs, blood and lust...or in other words, Let the Battle of the Genders begin. (Lime-y goodness, Gender Swap, Harry! Male, Zayn! Female, Louis! Male, Niall! Female)
