The Magnificent Milkmaid

The Magnificent Milkmaid is a webcomic by Prodigy Duck and Kris Overstreet.

It tells about an ordinary girl named Beth Dorman, who was given a dose of Super Serum (with an accidental dash of milk) by Mad Scientist Dr. Papilandrou, who is trying to test a formula for creating a "perfect sex slave". Instead, whenever she drinks milk afterwards, she uncontrollably grows into a giantess with large amounts of the Most Common Superpower -- and a few more besides. Now, she has to fight evil, and sexual frustration, as The Magnificent Milkmaid.

Gave rise to a spinoff, Chocolate Milkmaid, set a few years ahead of its parent.

=== Tropes included: ===


 * Anything That Moves - Almost all of the supergirls. Milkmaid is surprisingly a subversion; she CAN keep her raging libido under control if she really wants to.
 * Art Evolution
 * Big Bad - Dr. Emil Papilandrou
 * Bigger Is Better - Generally played straight, but JuGGGs, comically oversized even compared to her peers, usually gets made fun of for being too big.
 * Biggus Dickus: The aptly named Captain Cock.
 * Breaking the Fourth Wall: Hilariously parodied/lampshaded with Beth's mom.
 * Breast Expansion - all of the main characters have this power and one, JuGGGs, basically bases her entire life around her breast size. It's to the point that Milkmaid's super-strength is a Required Secondary Power to having such a bust. And, if she powers up too much, it's not enough to let her stand!
 * Clingy Jealous Girl - Karen Matthews aka JuGGGs
 * Clothing Damage - DUH.
 * Enemy Within - Prixen and Sweater Puppy
 * Gag Boobs
 * Gollum Made Me Do It - regarding to all of Milkmaid's enemies such as Chastity saying "It was the Prixen! She made me do it!"
 * Hammerspace - One of Milkmaid's powers.
 * Hot Amazon - most of the cast.
 * Hulking Out - Sweater Puppy and The Incredible Cunt.
 * Humongous Mecha - "Summon Mega-Milkmaid!"

 * Mad Scientist - Dr. Emil Papilandrou
 * Magic Pants - averted
 * Most Common Superpower
 * Mrs. Robinson - Beth's mom. Dear god.
