Star Jewel ~ STAR☆jewel ~ OAV 2 ~ Star Jewel Gaiden Natsumi Oblivion

Introduce yourself to an alien race distinguished between good and evil goddesses. Due to their treacherous deeds, the evil goddesses are banished to Earth.
They are trying to escape their banishment through collecting personality crystals that come from girls with whom they've had sexual contact with.
These crystals are used to power their “Sun Ship”, which will allow them to return back to their home planet.
It is up to the goddesses Natsumi, Reiko, and Mei to protect Earth from theses treacherous bunch and stop the evil goddesses from returning to their home planet.
Thus, the fight between light and darkness begins.
Both sides of goddesses are equipped with powers to battle, but their strongest arsenals are their retractable penises... flooding the enemy with pleasure is the only sure way to triumph...
Brace yourself for a blast of futanari...
