On Sunday, I email a picture of my bruised bottom, as requested. I also include one of my breasts so you can see the myriad of marks you have left there too.
I awake on Monday morning to the most delicious email, which has me stretching and wriggling on the bed with a massive grin.
He has taken to calling me Tigress, a reference perhaps to my new stripes... He flatters me shamelessly, calling me 'smart' and looking forward to both challenging and being challenged.
I return with something similarly flattering, though as usual I probably reveal more about myself than tell him anything he doesn't already know. Our emails swap back and forth, until I receive my challenge.
I'm not sure if you realize how galling this is to me, but something tells me you have a damned good idea....
"I want you to get yourself some nasty, slutty knickers.
You know the sort of thing that Top Shop sells to teenagers - pink thongs with the words 'taste my cherry' printed on the front in lime green, that sort of thing. The thong bit is absolutely vital, and the pinkness is important too (but any garish colour would do in a pinch). Other attributes, such as cheesy slogans, or pictures, or sheerness would be helpful, but are less critical.
I want you to have sent me a picture of you wearing them by the time I get home - at around midday on Friday.
Think you'll be able to manage that?"
I groan. This is just about my worst nightmare. I love lingerie. I am nervous and awkward about my body and the one thing that gives me confidence is wearing nice pants and bras. I like them to match, often they are large, cut to vintage styles and designed to show glimpses and tantalize, even if no one else will see but me. A thong is about the most repugnant thing I can imagine, and the colour pink is also to be reviled.
How can I do this? And if I do, how on earth could you EVER find me attractive after seeing me in something so vile?
I argue with myself, I send you a grumpy reply. I just can't help myself.
And yet...
And yet, I want to prove I can rise to any challenge you set me. My stubbornness and bloody-minded determination kick into overdrive and I decide I will find a way to complete your task.
On my way home from work I call into the shops. Surprisingly, the naff thongs you refer to are no longer as evident as once they were. Thankfully I suppose this means girls have realized good knickers are so much sexier and comfy...
Shamefully I trek from store to store, blushing as I head directly to the nastiest underwear they have on display. I grow determined, if I have to do this, I will make damned sure I find the most hideous undergarments London has to offer...
Finally I see them. Not just hot pink -- they are practically luminescent, dyed with radioactive pigment. In addition, they are made of horrid, artificial lace, cut to sit low, creating a horrible shape on any who dared to wear such a thing. The final, crowning glory however is the diamantes, a row of four, then three tiny little gems at the front. As I hand them over at the till I have to resist the urge to run, to stick my head in a paper bag, somehow to hide. The clerk handles them like the radioactive filth they are and I blush with embarrassment and anger at you for leading me to this moment.
Back home I take the photos and hope, without much confidence, that this will be the end of their place in my life. The images are truly, awful and I wonder if they will turn you off me for good.
Finally you return from your trip and you message me with instructions for our next date.
"Your safe word will be 'coconut', and I want you to be wearing the knickers when you arrive. Yes, those ones. Really. Don't worry; it'll be the last time you ever have to put them on..."
I growl and swear at the computer, but Monday rolls around and here I am, on your doorstep wearing the vile thong under my clothes.
We share a whisky by the fire and you question me about my experiences and reactions to the challenge. I struggle not to be too sulky as I answer your questions. The sadistic grin and twinkle in your eye soften me, and by the end of my recount I am getting moist, excited by what else you may have in stall for me.
"And you're wearing them now?"
"Yes," I blush.
"Show me, take off your clothes."
I strip, slowly removing my tights, pulling my top over my head and lingering over the bra. I pause, I have left my skirt till last on purpose, putting off the inevitable. As the skirt is removed, you take a sharp breath.
"You did well Bitch, they really are terrible."
I growl quietly.
"Stand up; show me," you command.
I rise and slowly turn for your amusement. Completely naked apart from the hot pink thong.
"Hands behind your back. Hold your elbows with your hands."
You get up and retrieve a bundle of rope from its bag. I shiver in anticipation, the smell of it hitting me as you approach and electrifying my senses.
Slowly you begin to bind my arms and chest, checking periodically that I can still move and feel my fingers. Each pull of the rope through the knots vibrates through my body and I am getting wetter between my legs. I revel in the sensation of rope sliding across and around my body, the pressure as it hugs and contains me, the smell of the oils imbedded in the cord...
My breathing grows ragged and I am turning to putty in your hands.
You pull something from your pocket and move behind me. A blindfold is pulled over my head and you tie it securely. I feel you moving round, adjusting it to ensure I am completely blind.
