We are parked at a truck stop, it is night the bunk light is on. You are lying back on the bunk, I am on my knees dutifully sucking Master's cock. Master reaches over and opens the driver side bunk door. Slave glances up, worried, but accepting. The Kenworth next to us also has a bunk door and the driver has it open to the cool night air watching TV. He glances up upon hearing the door open and his eyes widen with shock. Master reclines again and watches as slave continues to suck his cock. She is such a good little slave. He reaches down and pets her head, pushing into her mouth. The sensation of being watched and having slave's mouth sucking him are very erotic. He glances over, the driver is leaning closer to get a good look, dick in hand stroking, lustful glaze over his eyes.
Master reaches down and grabs slave's hair and begins to pummel her face, small gagging noises and moaning noises can be heard from slave. Master enjoys the sensation of having his cock deep in her throat when she gags. He enjoys proving to her who is the dominant, that she is the submissive and will take whatever he gives to her for he owns her. Slave begins to become sloppy, she can't help the amount of drool that seeps out when Master gags her and she is embarrassed to not do her job well. Master eases back and lets her resume her task on her own. He glances over at the dick stroking driver, turned on that he has something the other driver does not.
He suddenly gets up and lays with his head at the passenger side, he orders slut to get up on the bed on all fours, ass in the air, and continue to suck Master off. Slave complies, glancing nervously at the open door. Slave can feel the cool night air wafting about her ass, the delicious sensations created as the breeze hits her slickened pussy and thighs makes her moan loudly with Master's dick in her mouth. The driver's eyes widen even more if that is possible, for Master has placed a butt plug in slave's ass. She has a tendency to be reluctant to let Master in her ass, so to prove a point, Master is there all the time! Reminding her who owns her, who can and will use her ass anytime, anywhere he wants. Slave finds the plug very uncomfortable, but the message it sends has her pussy at a roiling boil.... Slave understands Master.
Master moves slightly so he can enjoy the view of her ass in the air, just mere feet from the horny peeping tom. He can see the steam rising from her ass and pussy area. He knows slave can't help it, she enjoys being made to perform as the slut she really is... and he being the sadist he is enjoys making her perform, slapping her in the face with the reality of the slut she is. Slave's head is bobbing up and down, flashing her ass and pussy at the peeping Tom. Master hears the peeping Tom groaning and laughs, he roughly grabs slave's head and hair and begins to face fuck her.
Master backs off and lets slave come up for air, large quantities of drool and precum string from slave's mouth to his dick and Master enjoys the site before impaling slave's mouth again and again.
Noticing movement, Master glances out the door, the other driver is making a pleading gesture and gesturing towards slave's ass and pussy. Master motions for the driver to come on over.
