Without further ado... .
OOB Enchant :
Magic Mirror
Can only be placed upon items that can produce a reflection. When cast, this spell produces an image (no audio) of a person or place known well to the caster, as they are at that moment. If used on a person, a Detect Magic spell would tell the person they're being observed.
Alternatively, this can be placed on two similar items at the same time, with the effect that these items can then only be used to scry each other, but can carry audio. Could be made permanent.
OOB Enchant:
Long-Ears
This enchantment functions in a similar function to a message spell, conveying the sounds around the item in question to other items linked with it. Items must be linked at time of enchanting, and are treated as always in "receive" mode, but must be activated to "send". If linked with multiple items, "sending" sends to all items linked to that particular item. Could be made permanent to be in always "send" mode.
OOB Enchant:
Trigger
This enchantment can only be used on items with multiple slots for enchantment, and has the effect of "triggering" another enchantment on the same item. A trigger must be specific, and detailed at the time of enchanting, and the enchantment it "triggers" must also be chosen and enchanted at time of casting.
A favourite of slave trainers, often used to trigger reward or punishment effects such as Pleasureful Pain or Sweet Bliss in response to, for example, swallowing cum, or using a particular word - say, Mistress.
Can only apply to OOB effects.
OOB Enchant:
Mimicry
This is used again to link two items, so that what is done to one, is echoed on the other. Most commonly placed onto books or journals, to create a rudimentary system of communication swifter than letters, or used by artists, to more easily copy their work.
Endless Ink
A very simple enchant most commonly used on quills, to allow them to write indefinitely without the need to dip them in ink.
Soft Enchant:
Simply : Causes spontaneous orgasm. I don't think that needs further explanation. Cannot be made permanent (?!).
