First real bondage

Mr. F is a 72 year old chubby man with erectile dysfunction. He has a fetish for toys and girls like me. We have met a few times now and just this past Saturday I reluctantly agreed to total control through bondage, some thing I had fantasized about but never fully allowed. Every meeting is a new adventure as his kink is to use what ever he wants to fuck me with, flash light, base ball bat (souvenir) bottle, dildos, actual toys....etc. I never truly know what's being used until its over and the pictures are reveled to me as I am blindfolded the entire session. I put on my sexy outfit and kneel on the leg pads of the horse, he blindfolds me and pushes me forward onto the arm rest. I hear the Velcro open on the straps, the first straps are just behind my knees, I feel them pulled tight, next my arms at the wrist and elbows are attached and finally I feel the waist strap tighten around me forcing my ass higher into the air. His hands grasp me above my hips and he pulls me back until my cock drops free of the horse. He slaps my ass a few times warming my cheeks. Using a syringe my hole is filled with cum lube .and the first object is shoved into my ass, I feel him begin to write on me with a sharpie.....another fetish of his. I have had my nipples played with a bit before but nothing like he had in store for me. I feel him grab my right tit and squeeze it flat followed by the burning stinging of what turns out to be a bar clamp, it forces the blood to my nipple giving it a tight swollen feeling, the pain shortly turns to a strange pleasure. Next the left tit and then the nipple clamps. I hear the click and the muted flash of his camera slips past the blindfold as he steps back to preserve his accomplishment's. This is the first time he has had me completely under his control and he takes advantage of this by slamming dildos into my ass hole with brut force, lube dripping from my hole and pre cum dripping from my cock. I can hear the wind in front of the crop strikes that make me wince with every hit. Due to his E.D. he finishes me off with a large strapon cock to give him that feeling of real fucking and control. He presses the head of his cock against my slut hole and in one quick stroke buries it deep inside me and before I can let out a scream he has a hold of my hip's and is power stroking my ass hole like he owns it and tonight he doe's, the force of his fucking is moving the horse, his cock is forcing me forward and his hands pulling my hips back onto his cock, this is dragging my swollen nipple's back and forth across the horse making me drip even more, I just wanted to explode with this brand new feeling in my tits. His cum covered cock is coming all the way out and ramming back into me balls deep, my ass pussy not having time to even close, not being able to catch my breath and not wanting it to end.......sadly it did end.....my hole breached.....a pool of my own cum under me.......exhausted, my legs shaking uncontrollable.
