I Was Kidnapped by Lesbian Pirates from Outer Space

Everything About Fiction You Never Wanted to Know.
Alice being Badass

Captain Janet: You know, That's some negative stereotyping. Just because I'm a lesbian doesn't mean I'm a thief.
Sally Speed: You're a pirate!
Captain Janet: A valid point.

Susie Bell, an ordinary secretary on Earth, attracts attention of an alien raiding party of lesbian space pirates, who believe that she is the long-lost princess of their planet and abduct her. That's pretty much it for the main story.

I Was Kidnapped by Lesbian Pirates from Outer Space (IWKBLPFOS for short... don't look at us like that) is a webcomic written and drawn by Megan Rose Gedris and published on Drunk Duck. First published in March 2007, it started off as a cheesy parody/affectionate pastiche of 1950's sci-fi pulp paperback comics featuring pirates, aliens, and lesbians. Recently, however, it's been suffering from Cerebus Syndrome and has since gathered a large fandom, thanks to its regular updates (which isn't the case with so, so many other webcomics) and... oh, come on, it has alien lesbian pirates from space!

Here's the link. However, due to a disagreement with the owner, Platinum Studios, the artist/creator has taken the comic down from the net, and has all but encouraged readers to download torrents of the webcomic. Yay piracy!

Tropes used in I Was Kidnapped by Lesbian Pirates from Outer Space include:

Sally: Is everyone you know really dumb?

Cashier: How will you be paying for these shoes?
Susan: Sacks of money with dollar signs on them.
