How do I get vials of cum and get into the orc village
I believe you should have visited her a couple times at the public baths and done the bukakke scene. At that point, you unlock her store location. Once you visit her store a couple times she'll say something about it being open at night. If you go there at night her club will be open and I believe you should be able to get the cum tank after visiting her club the first or second time.
