Bit of a walkthrough

So been through this. Story is a bit of a mess, feels like the start to an adventure but then it just ends. Characters are kinda one sided, only fleshed out in their respective paths.
Honestly Negligee has the better set up, three interns fight for a job at an underwear shop over the summer but here they're just kidnapped and placed on a ship. The story expands more from there but it goes absolutely nowhere after that. Does have a proper harem sex end though, which is something it has over Negligee.
Sex isn't bad but I don't know if I'd play again.
