More chemical potion

Some idea from the old game "corruption of champions" https://github.com/herp-a-derp/CoC-Alpha

Lact aid: stimulate lactation

Lust potion: get in rut

Ovi Elixir: accelerate to lay eggs (if possible!)

Succubi’s Delight: larger balls (thus more cum)

Can Rack2 have something like that? (functionally similar)

PS hope to have more chemicals on transformation either!
