 This was our first free Saturday in aeons.  I'd been looking foward to it
for weeks, and I had been planning this all week.  As soon as my slave
cleared the breakfast dishes, I got up and grabbed her hair.  I pulled her
roughly towards the bedroom, grabbing our knife on the way.  <lj-cut
text="Caution, not for everybody.">As we entered the bedroom, I thrust her
onto the bed.  "Kneel, bitch, and stay still." As she got up, I flipped the
knife blade out, making sure it locked into place.

   She knelt, but was none too still about it, as she always is.  Gently, I
pressed my free hand against her back and pressed the flat of the cold
steel blade against her shoulder blade.  At the touch of the steel, her
struggle ceased and her body relaxed.  My arm folded around her, and I
traced the back of the blade up around her shoulder, and down the
breastbone.  "You want this, don't you, love?"

   She nodded her head, and I heard an emphatic "Mmmhmm!"

   As she relaxed yet more under me, I started working her back.  Tracing
light strokes on her upper back, finding the pressure her skin could take
today, I heard small sounds come from her throat, like a kitten mewing.  I
knew now that she was well under, loving the sensation of the steel against
her skin.

   Satisfied I had the right pressure, I started doing more.  I traced some
symetric curves on her back, fashioning an elaborate arrow pointing
downwards towards her beautiful ass.  Never breaking contact, but instead
flipping between the point and the back or flat of the blade, my hands drew
beautiful light shapes on her pure white skin.  Satisfied with her back, I
traced around to her arms.  On her right bicep, I chose to trace a simple
caduceus, the doubly-entwined snake.  On her left, I traced a crude knife,
to leave her with the memory of today.

   At this, I drew back to look at my work.  Without my support, she fell
forward to rest on her hands, displaying her lovely back for my gaze.  To
my delight, the slightly raised mounds where the knife had passed glistened
with only a few drops of blood.  I grabbed my digital camera and snapped a
few quick photos for posterity.

   Coming back to my beautiful canvas, I pulled her hair aside to look at
her.  The content smile on her face and the look of ecstasy in her eyes
touched my very soul.  Casting my glance downwards, towards her luscious,
full breasts, I new I had one last touch to make before I was done.  Very
carefully, I traced the letters, from left to right, on her breasts: "S",
"L", "U", "T".  That done, I wiped the knife with a soft cloth, folded it,
and set it on a counter, to be sharpened later.  I needed to bring my slave
back up.

   I took a cloth, moistened it with an alcohol mixture, and wiped down the
marks I'd made on her.  She shivered as the sting from the alcohol bit into
the few marks from which a droplet of blood had sprung, but still sat
limply on the bed.  I carefully took her in my arms and whispered softly
into her ear, caressing her with my hand.  Slowly, she came up and shook
her head slowly, blinking.  A bright smile came upon her face, and she
looked full into mine, saying, simply, "I love you, sir."

   I carefully hugged her tight and lay her down on the bed.  I snuggled
next to her and my arms melted into her soft curves.  Soon, after I was
sure I had her full back, we'd rise and view the pictures of my work, and
take more.
