JAV where they enter a horror/haunted house or location?

[F-16]

And whoever gets scared or caught gets fucked, I only found two examples so far that sort of fits the bill HNTV-002 and HNDS-068.

+ they made a third one with Miho Touno.

That's all I know with JAV stars having sex.

If you're just into ghost hunting/entering haunted places with a bunch of guys plus one or two cute girls who sometimes only wear bikinis (no sex), there exist many more movies like it.

You can look around the Horror section in the Library...
