[Synopsis]

Sluts are women who enjoy obscene acts of filthy sex. They love sex! And each of them has their own sexual proclivities.
But they can't reveal it to others in their daily lives... and because of that, they can't release their desires, so they seek someone who can release them.
All men in the world are gentlemen and kind to women ! But... if they are targeted by sluts, they will end up being mummified, milked of semen and turned into their sperm tanks...
To train your eyes to not be milked by them, read this slut encyclopedia ! Watch out for these sluts!! (͠≖ ͜ʖ͠≖)
