Just a fun little game a friend of mine showed me.
Basically you choose a girl from some random anime (mostly Ranma girls) and 'train' them to be a (sex) slave.
It can be complicated at times, and the Engrish doesn't help. But quite addicting ^^;
Its kinda like the Princess Maker series... just more focused on sex! O_o
