It's a staple of every schlock horror movie ever. It's a dark night, and it begins to rain...Leaving a group of hitchikers/cheerleaders stranded. With no other option, they head (Like lemmings towards their doom) towards the scary-looking mansion in the distance...
This idea was initially inspired by a hentai game; The concept being that a small group of girls wander into what appears to be an abandoned mansion...Only to find it haunted by the perverted old ghost of the now-deceased Master. The Master is, of course, all-too-happy to have fun with the beauties who've wandered in for the night...
Generally, the idea I've had is that the place is filled with all kinds of erotic temptations and traps, and has the power to force certain perverted scenarios upon the girls...And the influence gets stronger, the longer they linger! For example, a girl who decides to take a nap in the bedroom might find herself forced into a *very* realistic...And very
erotic dream - Similarly, a girl who takes the chance to shed her wet clothes for a nurse's outfit might find herself in the role of a nurse, made to 'attend' to her lord's suspicious 'swelling'...Until she manages to break out of the fantasy~! Works of erotic art might suck them *right* into the picture...As the subject of the painting!
I like the strong element of temptation/corruption to it...Ideally, there should be way to resolve things, but the longer they stay, the *less* they want to leave~! As an extra element, if some guys were along for the ride, there's no reason why they couldn't run afoul of a sexy demoness/vampiress looking to make sure they stay...FOREVER.
While I'm at it, I'm looking to making things as perverted and naughty as possible. It's not an issue of romance ~ The girls are in for the night of their lives! I just love the contrast of ugly old perverts on hot young women ~ Or horny monsters getting their grubby hands on beauties would should *usually* be fleeing them. For the feel of it, think a softcore hentai movie...One of the fantasy ones where the heroines don't get away in time!
As an alternative to the old haunted mansion, they might be on the house of an acclaimed porno director - Which explains the fantasies and fetish costumes they keep finding in that luxuriously-appointed manor! Of course, they now have a starring role in their *very* own erotic horror film...http://dl.dropbox.com/u/8073552/01c1.jpghttp://dl.dropbox.com/u/8073552/siru26.jpghttp://gelbooru.com/index.php?page=post&s=view&id=750585
edit: This is an overview of that game.http://opphiucus.wordpress.com/2010/05/12/kaiki-drill-otoko-no-kyoufu/
I'd assume that the girls are very much archetypical: You have the cheerleader/student council president, who secretly longs to 'slum it', the geeky girl with a lifetime of fantasies to live out, the Goth...And so on. -_^
Will they *ever* escape/break the curse? Or will they be *changed*, into the house's very sexy minions, by the time morning dawns?
