Sorry for the delay - and thank you responses to date - very flattered.
Luckily - or unluckily, we are pretty remote, so very few unexpected visitors; though Murphys law etc!
Rapidly realised one reason for this, MIDGES! Having had very little experience of thin tights ( opaques got changed to fine denier ) in the woods at high midge season until friday night, I can now confirm they offer zero protection.
I was dressed as promised and led out into the trees. Despite having closet dressed for years, its been around the house or quick amble in garden. I love the feel of heels and walking in them a reasonable distance was bliss. However, not designed for 'off-roading'. Anticipated sinking heels, but hadnt considered just how many sharp pine needles and small vicious twigs there are when tootsies only clad in 'dainty' shoes and tights. That said, my discomfort seemed to turn J on greatly and that made me tingle too.
With some experience of being tied we went for fairly loose bonds - secure loops around wrists and plenty of play so arms didnt get stressed.
Having read through the forum, J quite buzzing with ideas. I was left for about an hour in light drizzle then she came back to see how I was - and not least gloat. Whilst wanting to be gleefully 'got', this fetish ( for me at least ) needs to follow who we are. In 'real life' my partner is my soul mate, I need to see her happy. Indulging my fetish aside, I was delighted to see how much she was actually enjoying this. Its early days, but reading here has helped J undestand how my mind kinda works. She isnt looking at it as being truly nasty to me anymore.... gulp!
I was fairly uncomfortable by that stage - with static position, strange clothing, drizzle soaked and those midges. My heart ponded as she said I looked far to settled for my own good. The next bit I suspect I can blame Hayley for - not strictly gross, but pretty yucky. J had brought a tub - the drain off from a roast chicken two days earlier. It was congealed chicken fat, juices and assorted gooey bits. She held it in front of me so I could see. She then set about shampooing it into my hair, over my face and took particular care to push it in my ears - yuck. The smell and feel was incredible, all the more compounded by having no choice - I was in heaven.
Not a further word was said, she just walked off.
She returned about 12. Untied me and pushed me toward the track - more stabbed feet!
She stopped me on the track and spent about twenty minutes making me walk up and down - until it was lady like enough. Then made me walk to the ruts.
Even through the chicken guck facial I could smell the stagnant peat slurry. I stopped at the edge only to be pushed forwards. She told me to slowly walk in. The edge was sticky mud, quickly edging to a liquid slurry about two feet deep with soft clingling mud of about 6 inches on the bottom and a drier scummy layer about 2 inches on top.
I found a section that came to the top of my thighs - soaking the bottom of the dress. J had me stop, move to the side and face her. I had to lift my dress, tucking it in my bra. She had me pull my tights and knickers down to mid thigh. The moon was strong enough to see ok. She took a handful of green slimey scum and 'washed' my genitals thoroughly. Taking more scoops she worked it between my legs and into my bottom. This brutality was accompanied with lots of gleeful giggles.
Finally she gathered and double handful of slime and vegetation and dumped it into the gusset of my knickers. My fingers were too cold/ slick by this stage, so she reached and roughly pulled up my panties & tights. Untucked my dress and smoothed it down.
I was told to kneel in the slurry. The feel as the filthy peat water saturated my bra was incredible. I got about three seconds to enjoy as she grabbed my hair and forcefully - but slowly- tipped my head forward dunked me right under. Breath play is one of J's interests - I dont like it much at all. Sounds maybe strange, but it felt wonderful that she did then held me under - probably for all of 7 seconds, but enough. I loved her for that. To my outlook she showed me she loved me enough to do what I wanted - to take control, to use me as she wished - that make any sense?
Must point out that we know each other and trust is total and I mean total.
She brought me up, laughed - but did check I was ok - then I got the same again - repeated about two dozen times.
I was then pulled to the side and climbed out - unexpectedly hard in a plastered dress. I was walked home - again stopping to be forced to walk like a girl - in so far as a lump like me can. That 500 metres was exhausting - the dress sagged with the weight of the peat mud and clung to my legs.
At the house a pallet had been set on end and I was stood against it. Cable ties held my wrists to the frame and J got out the washer - which thankfully has a warm setting. I got a very soapy hosing for about twenty minutes. Then released, stripped and another hosing.
Finally went for a long, long shower and got to bed early Saturday morning.
Saturday J made me dress as a man - boo!

But did make me hand wash my clothes from the last night - tights and knickers were scrapped. The bra and dress took ages. I dont care what Persil say, peaty brown is the new shade of white!
The shoes survived and are still drying.
The tingle between us is still there. Had house chores to do this weekend - mainly tidying out the barn. Taking ages as we constantly stop and just cuddle/ hug. I think/ worry too much about everything. Repeated that she needed to be happy with this - I need her more than anything else.
Think got answer when I turned round yesterday afternoon to see J approach with a tub and an evil smile. My heart pounding I stood placidly. No words, no preamble she slowly tipped the tub over me - contained dirty sawdust and unidentifiable 'bits'. She pulled out the neck of my tee shirt and made sure lots went down back and front.
J then rubbed the sawdust thoroughly into my hair. Then made me carry on tidying up - it was four hours before I got cleaned up.
We have continued to bat ideas about for August. My hair is going to be left to grow longish. Seems I am definitely in for a permanent hair dye - but I can get away with a number one cut for going back to work and my hair grows very fast. Anyone got either the Express or Mail on Saturday - theres an ad for hair dye with Davina Mc - likely thats the colour I'm getting -
In terms of scenes/ mess, J quite interested in seeing what comes up on the forum. I particularly liked the lumpy gravy/ semolina suggestion and mushed up shreddies are incredibly yucky - thank you!
Toward the 'outer limits', J thinks I should be made to wet myself whikst dressed and tied. In addition, an incident from her childhood - where she sat in a cowpat ( by accident ) in a short skirt and cotton gym knickers and was made to ride home in the car dressed in the gooey clothes and sat on a plastic bag for two hours has given some fairly broadminded

ideas for horrid schoolgirls to punish hostage school mistresses.
Sorry for ramble, things have kind of snowballed these last few days. New for J and very much realisation of a lifetime of dreams for me - so bubbling over a bit.
Think people here will perhaps understand more than most, though may seem strange. Something apparently so perverse is actually very much secondary to love and closeness. Hope this thread helps others either with uncertain partners or at least feel less isolated or unusual.
Please do let us have any further ideas. J is thinking that maybe could take none- compromising photo or two in time just to prove not a lonely Lenny ( her term ) and to say thank you.
