Ty remembered back to a interesting thing he read about online. It was a simple enough concept, but if it actually happened then it would be very interesting to see the aftermath. It would be a simple change, but one that could drastically alter how we see the world.
Ty thought up about how the virus would act. The virus itself was an STD and while it would affect both male and females, the greatest effect would be on females which would be cool. The effects for males would only detail three things: increased libido, increased fitness and the acceptance of public sex and nudity. For females, that's when things would get interesting.
The symptoms for females would first start out small. It would be an ever so slight increase in sexual desires and interests. This would also cause an increase in libido and wanting to relieve themselves with the first man they see, although they would still act modest in public. During the first few days, woman that are above the age of forty would begin to look younger until they could pass for 40 years of age.
Past the first week of infection, then physical changes will begin to occur for females. For girls above the age of 15, their breasts would increase slowly until they would range from either D cup to G cup depending on their age and other factors. For girls below this age, they would be affected until their 15th birthday. The other physical changes during this stage would be their level of fitness. Females would have a slightly more curvy figure and would be able to run faster and much longer then could previously.
By the 2nd week, the affects on females minds would begin. The virus would make it so that females that are in or have gone through puberty would become more interested and less modest. They would begin flirting with any male that takes their interest. During the 2nd week, woman would also begin to wear more revealing clothes and would be less modest. This often will result in public indecency but due to other people being affected, the police won't do anything to stop it.
The last symptoms would be in the third week, the most drastic changes would occur here as the structure of female anatomy changes. Depending on certain factors, woman of any age will begin to transform into a monster girl. Most of the time, woman in the same family will often change into the same type of monster such as a daughter and mother would become lamias. By this point, the minds of woman would still be able to do other things, but since their lust and strength is incredibly high, the first thing they'll do is rape their crush/boyfriend or husband. In cases of lesbians, while they would begin to feel attracted to men, they will begin to mostly pass on the virus to other woman so that more monster girls will form.
With this idea in his head, Ty waited for the virus to infect its first victim. It was going to be interesting to see how humanity would be affected by this virus.
