I arrived at the parking lot right on time. A white van pulled up and my master opened the door to reveal a mobile dungeon. "Strip!" was the command I heard and without thinking I began to remove my clothes. When I reached for the waistband of my panties I felt the chill of the wind and looked around the empty parking lot. No one around to witness me standing naked next to the van, no one to see what would happen next.
My master told me to put my hands behind my back and I heard the click of the hand cuffs as they squeezed tight around my wrists. His strong hands bend me at the waist and a sharp slap on my inner thigh reminds me to spread my legs. The cool liquid lube makes me jump as he inserts the anal plug in to my anus. Pushing gently at first then shoving hard as the plug seats itself deep within me.
Still bent at the waist my hair is pulled back and tied in a strict pony tail. I am forced into the van on my knees. I have to straddle the round hump attached to the floor, my knees are attached to ropes that keep them spread wide. In the center of the hump a large rubber cock impales me, his hands on my shoulders force me to take the monster all the way in.
My arms are attached by the handcuffs to a rope that pulls them up behind me forcing me to lean forward slightly. My pony tail is pulled down and tied pulling my head back revealing the fixture attached to the roof of the van. It's a long thick dildo that is adjusted to go down my throat enough to make gag slightly.
I am now completely immobile in the van but he wasn't done yet. I feel the cold hard clamps bite into my nipples, pinching and pulling on my tender buds. The chain attaching the two clamps is attached to a heavy weight and draped over a bar in front of me pulling my nipples straight out and stretching my tits cruelly. A third clamp in attached to my clit causing me to moan around the fake cock in my throat as it is attached to a heavy weight of its own.
The door slams shut and I am in darkness, the back of the van has a wall separating the driver's compartment from where I am imprisoned. I did not see my master pick up my clothes from the ground outside the van and I realize I will be naked for as long as he wants.
As the van rolls down the road the bumps drive the dildo and the plug deeper into me. The acceleration causes the weights to swing and tug harshly on my clamped nipples and clit.
It was hot out side but it feels like the heat is on in the van. I can feel the sweat rolling down my body and it only feels like its getting hotter, then without warning the air conditioning comes on full blast! Now I am shivering as my sweat covered body cools rapidly. The goose bumps cause my nipples to harden and the clamps bite even harder than before.
The van comes to a stop and the heat is back on again. The weights swing wildly and pull my tortured nipples and my stretched clit harshly. The door to the van slides open and the light blinds me momentarily. The light is bright only for a minute as my master ties a blind fold around my eyes and starts to release me from my bonds.
First the cock in my throat is removed but before I can gasp a large ball gag is put in its place. Next the knee ropes and the ropes pulling my arms are removed. My master pulls me roughly from the cock impaling me and I moan loudly as the weights drop and jerk cruelly on my nipples.
The weight attached to the clamp squeezing my clit drops from the van next and bites hard as it reaches the end of its tether. Tears well up behind the blindfold as I am lead away from the van, each step sends searing pain through my nipples and clit.
I hear the door shut behind me and I sense I am inside again. The hand cuffs are removed and replaced with thick leather cuffs that are also placed around my ankles. The cuffs are then attached to chains that are pulled up and I am lifted off the floor by my wrists.
