"An anal hook to secure you!"

"We can't have you wiggling free as I apply your mark!"

Your heart sinks as you rest against the bench. All slaves, even initiates, are properly ass trained, but you had hoped for something easier. At least you had complied with your mandatory daily enema.

"Yes, sister" You agree.

You hear metallic clattering and instinctively attempt to turn your head to see. Nope! Your collar has your face firmly imbedded within the thick padding of the head cradle.

"Calm down girl" Désirée says while making soothing motions on your upper back, "I'll show you."

There is some more fumbling before the hook is held beneath you within view. It is a hooked metal bar capped with a 1 inch ball at the end. It was definitely up to the task of securing you. Hopefully your ass was up to the task of accepting it! You whimper uncertainly within your restraints as the hook disappears from your vision.

Désirée sings softly to herself behind you. She is a woman who loves her work!

"Ugh..." you grunt as someone's heavily lubed finger plunges into your asshole.

"There you go." Désirée encourages you. Her finger slides in and out of your back entrance ensuring you are properly lubricated.

SLAP!

"Up you go!" she says playfully slapping your ass.

You lift your butt off the bench as instructed and brace for the inevitable. Your thong strip is pulled aside and you feel the 1 inch ball of the hooks tip press against your little back entrance. It is slick with lube but doesn't enter. You grunt with effort over Désirée's soothing noises as she applies more pressure.

"Uuuuuuaarrgh..."

Tears spring from the corner of your eyes as your asshole stretches around the sphere. She gently rubs your lower back encouragingly. I will be marked with honor! You think as you raise your ass back into the probing hook. Your knees shake with effort.

POP!

"Ummph!" you grunt as the ball breaches your protesting sphincter. Your legs buckle resulting in another corrective SLAP to your bottom. You hear some of the other girls gasp. They are no doubt concerned over their shared fate. You lift you ass again and endure the hook forcing it's balled tip further up your bowels. You whimper as you shift your hips under Désirée's guidance as she aligns the hook along a rail within the bench. Once affixed, the hook angles your stomach snuggly against the bench below while forcing you to arch your perky ass into the air behind you.

"Good girl!"

You melt under Désirée's prays.

"Time to begin!"

You hear the sound of a hand-held marking laser behind you. Over the next 30 minutes you endure the tattooing of your lower back with bravery. Sweat roles down your face and you occasionally shake with effort. You are proud to have controlled yourself through the process so well. Never once did you protest during the process.

Just when you think you can't take anymore Désirée announces her completion! You have been properly marked and she can't wait for you to see the results.

"We just need to remove the anal hook and your done!"

Oh boy... You think bracing yourself...
