What sex virus ?
That was a media spin about serum... ( at the end of LE a truckload of it fell into the drinkwater reservoir of Santiva ) and people couldn't make it out why people get horny all the time
It’s actually pretty interesting to follow the Serum throughout the story.
It first appeared in Lust Epidemic, where the scrawny nerd (can’t remember his name) was mass producing it. Although he could only make more from what he had, but not make it from scratch, which means he did not invent it. And we still don’t know who did.
At the end of LE Brad dumped a truckload of it into the drinkwater reservoir of TON’s Cape Vedra (not TGO’s North Santiva).
Then in Treasure of Nadia Emily was experimenting with the Serum, learning how to produce it from scratch. For that she needed plants that grow on Casula land. So perhaps the Serum was invented by the ancient sex-obsessed Calula natives.
Eventually Emily created a self-replicating Serum formula that later turned out to be a
virus. The infected girls were cured by Henry’s creampies, and all the samples were destroyed. Except before that Emily gave a sample to LE’s Brad for testing…
And then we jump to The Genesis Order. Everyone is just as horny, as in TON, even though North Santiva’s water was not spiked by Serum. However there is a news report about a “mysterious sex virus”.
P.S. Yes, I play these games for the plot.
