Angraecum

A short 5 chapter Hentai series written and drawn by Otsuka Kotora. The series protagonist, Akito, has two travellers wearing Nazi-esque clothes from another world crashed into his room. The two girls are February Akashic(Feb for short) and Mila Safeguard, who ran away from their strict totalitarian world to see what it feels like to not be monitored 24 hours a day and have all physical relationships outlawed. Sex Ensues.

Later on, a third girl, Dualis, joins the cast. - === Provides examples of: ===


 * A Nazi by Any Other Name: The world the girls came from sounds like it's based entirely on WWII era Germany. And their uniforms are clearly based off of Nazi uniforms.
 * Crowning Moment of Heartwarming:
 * Defrosting Ice Queen: According to Mila, Feb was almost never smiled back in their world, and due to the strict laws of that world, Feb has never wore any make-up nor has she done her hair until now, which Feb replies is because she fell for Akito. When Dualis joined the group, she had a similar conversation with Mila and revealed that this was also the case for Mila as well.
 * Fetish Fuel: This is probably the main reason why Feb, Mila, and Dualis spends the entire series wearing their Nazi-esque uniform.
 * Dualis was promoted to officer at the age of 14, while Mila and Feb were promoted to prominent position when they were 16.
 * Putting on the Reich: The girl's uniforms are very clearly based off of Nazi uniforms...with the swastika altered slightly. Justified since they're not really Nazis, just otherworldly travellers that came from a militaristic totalitarian world.
 * This is how Akito got to be on their side.
 * Time Skip: The epilogue at the end of the story.
 * Title Drop: The title of this series is explained by Akito in the Time Skip.
 * Token Loli: Dualis
