Hey not bad I like it alot (Tho I got an idea If it possible it could be fun)

The idea is something like this:

Give the ability to choose the female personality, And maybe also had a hiden stats that change over time (influenced by time of day, Str compare to yours, personality (probably a mutilicator) etc.) and at the end a number could say if the women let you drink a benefit possion or steal it and drink it herself or if she make you drink negative possion...

(I don't use the possion on the main character alot but it could be nice to have a personality and bio rithme that make girl able to steal good possion form you. It would also help your character keep haveing stats to steal whit demonic things if she fail to steal it), Tho I would alwas make it random so it give it more of a gamble I think it would be fun...

Any way hope you like the idea... SORRY FOR THE BAD ENGLISH Hope it clear what I mean.
