CONTAGION!

Transporting to the ship in their short 'TOS' Yeoman mini dresses Sarah, Cameron, Alicia, Sandra and Nicole are unknowingly infected by a virus (and yes I'm borrowing the plot from 'The Naked Time') with a twist.

Seeing only dead bodies and finding no survivors they return to the Enterprise being decontaminated... _or so they believe! _As expected everyone they come in contact with, bridge crew, medical bay, and security personnel are infected, as well as other crew members as it spreads throughout the ship.

Fortunately the male crew members are not affected...why you're probably asking? The presence of the Y chromosome with the 'SRY gene' in a males XY chromosome is the primary factor in preventing the virus from infecting the men.

The female crew members are not so lucky having a 'double XX' chromosome, their sex drive is primarily influenced by the brain chemical dopamine and the hormones estrogen and testosterone whose release is tripled by the virus. The raised levels of estrogen and testosterone increases the womens libidos promoting lubrication and desire, while the increase of their dopamine levels is linked to sexual excitement and motivation, finally the growing norepinephrine levels stimulate their arousal and horniness to be fucked!
