Blueberry Virus

Added "infectious" blueberry juice, which makes you swell depending on how much you have inside of you (also turns you blue). While you have some inside, clicking on yourself with a beaker will juice up to 10 out of you
Added this juice as an option for genitals fluid
Added Berrification virus, which makes you produce juice. It is a level 7 virus. It can be cured through normal virology means or by getting all infected juice out of the person
Added a "Blueberry Inflation" preference (juice will disappear when inside you, virus will not make you produce)
