Space Babe Yukino

During the exploratory vessel Kikumasa's mission beyond the Milky Way in Space Age 216, its sonar detects an unverified energy signature. An excursion pod, designated number 18, is sent to investigate, carrying crew member Yukiko Akagi. Her pod collides with an unidentified object just three days prior to her scheduled wedding. Upon regaining consciousness, Yukino finds herself surrounded by male aliens. These beings, created entirely from cloned embryos, possess forms similar to humans but have no prior experience with females. As their initial encounter with a woman, Yukino becomes the subject of their complete and untamed sexual impulses.
