Finding my self...self bondage that is

My first experience with self bondage was purely awakening , to a life of indulging in this secretive lifestyle.
I had already been involved with some friends being tied down for tickle torture games and I was desiring that feeling of helplessness and erotic pleasure.
One afternoon my parents had headed off and I was left alone at home.
So with a few silk scarfs I decided to try some different ideas,the first thing I tried was some simple loops one around my wrists and the other around my bed end tugging and giggling to myself as it was easy to release and exciting each time I would pull the scarf right around my wrists I would shake and shiver like never before!
After a very short time I decided that was fun but not thrilling.
I thought about the fact I was safe at home,so I tied my ankles and lower legs together passed a looped scarf around the binding,laying on my belly I folded my legs back and then putting my arms behind me I passed my wrists through the loop and pushed my legs back towards the ground effectively tightening the scarf around my wrists in a sort of loose hogtie!
I was hooked and even though not very tight I was sort of stuck wriggling around giggling my excitement built quickly and with a bit of adjusting I was loose and running to the toilet in desperate need Of a wee!
With new determination I decided I needed something more.So into the back shed,into the cellar,my heart pumping as I set about my plan.
A rope thrown over an exposed beam with a caribina one end and the other tied securely to a heavy steel cabinet handle.passing the looped scarf around my wrists I was able to easily place the looped other end in the caribena,this was not nearly as exciting as I was looking for.
I wanted my feet tied to,and a more perilous predicament.
So I decided that what I needed was a less relaxed situation so I set up what I thought would be a simple get out-of .So I sat a old tool stand base my father had In there and attached a wooden chair leg with a nice ribbed end to it.
Standing on tippy toes the round top nestled into my still almost virgin pussy,I had been fingered but not had anything else in there,I then gave myself less rope but saw if I slid the scarf into the caribena then walked forward it would pull the top tighter forcing me slightly forward but lifting my arms up so I would be bent forward arms behind my back ,,not enough so I then tied a scarf betweeen my ankles,I then went the next step and taking a deep breath I then stuffed a pair of panties in my mouth and then wrapped a scarf around my head.
I carefully clicked the scarf into the caribena and then shuffled around until I was in tippy toes over the wooden leg with the end just almost teasingly touching my now wet pussy I also decided being naked was appropriate and I noticed how hard my nipples were on my small breasts.
I soon realised that I was exactly where I wanted to be within minutes I was aching my arms my feet my arched back my thighs and my moans through my gag were letting me know also.
My breathing was heavy but my heart pounded at what I had done I was revelling in the moment when suddenly a rat ran across the floor!
I shrieked and forgetting my footing tried
To jump,,
What happened next,,,I cannot describe I pulled the rope and the cabinet swung forward not actually lifting me but it left me unable to shuffle away to release the scarf,,my feet were aching and the only relief was to lower myself onto the wooden leg which pushed the rather thick end into my small pussy opening so between trying to tippy toe,,and also rest and also the fact that I was now trapped and my parents would be home at some time!!
Shaking and scared and excited as my feet aches my breath shortened and I winced as I slid over the wooden leg my little pussy opening spreading.
Tears trickled down my face as I felt it slide in further trying to push up only to slide back a little more then my arms pulled tighter I was in a fix with no out and it was the rat running back past that caused me to lift my feet ,,sliding into the leg I almost blacked out as I felt the leg slide in I was wet I was excited and then in the middle of all that I actually orgasmed !
Trembling my feet flat as I moaned into my gag the wooden leg in my once almost vigin hole,shuddering as I felt my self release a little wee hearing it trickle and pool at my feet .
Shuddering as I try to move which results in my feet aching as I try to push up lifting myself off getting to my tippy toes and holding as best as I can only to end up sliding back onto the merciless piece of wood.
Shuaking I realise the only thing I can do is hope one of my parents find me when the rat runs out and over my feet I squeal at this and jump which amazingly gets me off the leg and to one side releasing my tight posture.
Shaking as I manage to unhitch my aching arms from behind shaking as I untie myself and redress.
I smile at the glistening chair leg and giggle at the wet pool of wee.
Waiting on the house shortly after the phone rings my parents asking am I ok to spend the night by myself.
“Yes of course dad love you both”
Hanging up the phone as my hand reaches for the back door,,,
