When installed in your MA HUD, Poly enables other people to 'open' your hud without them needing to be your 'MA partner'. It is the new name for what was previously called 'Forced'.
After purchasing poly, installation is easy:
add it - and that is all. it will detect your HUD, install itself, detach.
After installing Poly, you can call it up via
HUD - Assistant - Add ons - Poly
Poly on = Enables the Poly option
Poly off = Disables the Poly option
blocked = allows you to block Poly for selected people
the sign being grey means, the poly option is not active
the sign being yellow means, the poly option is active
If a male approaches you while you have Poly active, they can select in their menu "OpenPoly". That way they can initiate the mating, much as if you had opened to them.
During mating, if you as male have poly active on your HUD, the female gets in her HUD the option "Make M cum" - that way she can make you ejaculate in her at her bidding.
If you wish to exclude people from using your poly, you can select the "blocked" button. Now you can add blocked, remove blocked and also see who is blocked.
