Hikari: First Interlude - v0.04.13p by Hikari-Comics Win/Mac - Adult Sex Game

Please join us and meet our trio of prospective lovers: Sasayaki, the rouge princess with a secret agenda;
Tsuki, your undead servant who must feed on your essence to continue living, and Hikari, the mysterious heroine of our story whose origins are a mystery even to her.
They travel on the MFV Aquilla, one of the last cargo ferries left in the galaxy, filled with dangerous and beautiful women and commanded by a pervert who owns them all.
Will you be able to free them? Will you lose Hikari and the girls to the Captain's greed?
