Beautiful Slave Girl

Go Go Enslavement and Bathe Her and Bring Her To Me both are based on the idea that enslaving a beautiful woman is exciting. It's about dominance and power being combined with sex which apparently turns some people on.

A girl who is born a slave and then grows up to become beautiful is instead about the contrast between her beauty and her circumstances. "A lily among the weeds," nevermind the Unfortunate Implications that other slaves are all weeds, beauty is a measure of a woman's worth, and that it's okay to enslave men and plain or ugly women.

This trope has an obvious dark side. Many of these girls are So Beautiful Its a Curse, forced into wearing revealing clothing and often raped by their masters. Because of this, it's more likely to be the setup to a Rescue Romance. There is also more likely to be emphasis on the girl's purity as well, and the idea that goodness and beauty can be found anywhere, not just in prosperity.

Far too common in Real Life throughout millennia wherever chattel slavery existed.

Only beautiful slave girls that are born slaves or enslaved before puberty should be listed as examples. Post-puberty examples can go into Made a Slave.

Anime and Manga

 * This is basically the premise for Dear S.

Film

 * Varinia in Spartacus.
 * Almost all female Twi'leks in the Star Wars universe. Ironically, the most famous one, Oola of Return of the Jedi was (at least according to the Expanded Universe books) the daughter of a chieftain who was tricked into slavery at Jabba's palace after thinking she'd been hired to a prestigious engagement as a professional dancer and would be free to leave when she wanted.
 * Though it should be noted, they occasionally become Jedi or Sith.

Folklore

 * The oldest known version of the "Cinderella" story features Rhodopis, a beautiful Greek slave living in Egypt, who ends up married to the Pharaoh.

Literature

 * Taura in Vorkosigan Saga
 * All slave girls on Gor are beautiful. Even the most stunning super beauty from Earth would be only slightly above average on Gor.
 * Maeve of Victoria Hanley's The Healer's Keep. The B-plot of the book involves her escaping slavery to avoid becoming the Sex Slave to the Big Bad. And yes, Rescue Romance is involved.
 * Haydee in The Count of Monte Cristo, who was enslaved as a child.
 * Conan the Barbarian has rescued his share of these. Olivia from Iron Shadows in The Moon, for example, was an Ophirean princess sold by her parents for refusing to marry a prince of Koth, and eventually fell into the hands of the cruel Shah Amurath, who mistreated her horribly before she escaped the palace and was rescued by Conan after the Shah himself tracked her down.

Live Action TV

 * The Orion slave girls from Star Trek, though it's debated as to who's really in control.
 * In an episode of Star Trek Enterprise, this is heavily subverted, because it turns out that Orion women rule their society, using hormones that More Than Mind Control all men. This has become Fanon Discontinuity for obvious reasons, and the recent Star Trek film seems to have made this outright Canon Dis Continuity.
 * Spartacus: Blood and Sand: Being set in ancient Rome, most of the slaves, obviously. Batiatus and Lucretia are fond of having slaves act as fluffers before they get down to business with each other; and Ilythia has her handmaiden "stimulate" her at one point. Invoked with Mira who is (repeatedly) sent to Spartacus to act as this. She is implied to have been this, possibly for much of the ludus, as well. To his credit, he turns her down as she is not there willingly, though they later become willing lovers. Naevia is an interesting example, Lucretia protects her virginity, but only so that she will be worth more later.
 * Pietros is a male example, though he and Barca genuinely love each other. Gnaeus on the other hand...

Theater

 * The titular character of Aida, an Ethiopian slave brought to Egypt and forced to work for the princess. Unfortunately, the guy the princess likes falls for Aida instead.

Real Life

 * "Fancy Girls" were usually attractive mixed race women who were specifically groomed and sold as sex slaves or house maids during slavery in the U.S.
