In the year of Space Age 216, beyond the limits of the Milky Way, the sonar of exploratory vessel "Kikumasa" picks up an unconfirmed energy signal. Excursion pod #18 is dispatched to the location. Yukiko Akagi is the crew member aboard that ill-fated pod. Three days before her wedding day, Yukino collides with an unidentified flying object. When she gains consciousness again, she's surrounded by male aliens. Born entirely from cloned embryos they are similar to earth forms and they've never seen or touched a woman. Yukino is their first contact. She receives the full and untested force of their sexual release.
