Sex with windows, lockable door and one with glory hole.
As you exit the dungeon you will find three small, wooden, semi-private cabins, comfortably accommodating two people each.
If you fancy a play with a little less BDSM involved, disappear into one of the three cabins with your partner. Each one of the cabins does have a window so you are not entirely private. However the doors are lockable.
Two of the cabins have glory holes and the third cabin does not.
Take your pick.
