Her bondage is way to lenient

Looking at Augustine glaring at you, you smirk. "Hmm, somethings missing." Opening the C-Collar cupboard you pick out a thick black leather posture collar. She tries to pull away, but with ehr legs cuffed to the desk + the armbinder she can do little more than lean away. You easily push her down and place the collar around the neck and buckle it on. Its stiff sides now hold her place pretty much forward, and she can only move it up and down a bit.

Checking the desk itself, you see a pair of very fun hooks. One is a nose hook, and other an anal hook. Augustine can´t see you, but you hear her breathing pick up when she hears you giggle. With a evil plan forming, you check around the office for some extra straps and a set of nipple clamps. Augustine looked at them worriedly but knew she could do nothing to stop you.
So, on quick order you undo her blouse to expose her breasts, clamping down the nipples, and putting the connecting chain over the abck of ehr neck, yanking them up hard and making her scream and gasp. You then press her down on the desk and strap her down to it using the straps, connecting them to cleverly placed loops on the sides of the desk. You then press the anal hook against her asshole. She tries pleading for mercy through the gag, but all that comes out sounds like gibberish.
So you slowly, but forcefully, push it up her ass until it bottoms out. Grabbing a piece of string you attach it to the ring at the end of the hook and tie it to the ballgag and tighten it as much as you can. This ofcourse pulls the ball deeper into her mouth, and also pulls her head as far back as it can go.

Walking around to her front, you give her a wide grin. The formerly so domineering woman was utterly helpless, alone with you and strapped down tightly over the desk with a pair of nasty nipple clamps painfully pulling at her nipples and a cold anal hook pulling her gag back into her mouth.
You hold up the nose hooks, making her groan and give you a look saying "Please no..."

You put the hooks up her nostrils and then attach it to the posture collar using a string, then tighten it bit by bit, pulling her nose further and further up until it looks like a snout. As you tie it of you see small tears starting to roll down Augustines cheeks...
