The Bimbo Virus: The Complete Series is a set of stories by Neil Bimbeau about a world in which a virus turns women into willing bimbos, ready to be used by men. Pretty much a freeuse world, because science. ;)
“In the near future, the world is ravaged by ‘The Pink’, a virus that only infects women. It decreases their intelligence, removes their inhibitions, and turns their bodies into perfect, submissive vessels for any hot, hung alpha male who wants a turn! Whatever walk of life they came from before being infected, these girls are on their knees, spreading their legs and begging to have their fertile bodies used again and again! “
Over 200 pages of freeuse erotica for just $2.99 seems like a sweet deal to me.
