I picked her up from work as the timer started. 30 minutes before I had to be back in the parking lot and making my own way in to work. I drove, dismissing her words to the spot I had picked out, knowing that it was quiet and I was unlikely to be disturbed. As I pulled off onto the dirt her voice became nervous, that was about all I picked up on as my rage turned her words to a blur. 22 minutes remaining.

Before she even had chance to think I threw off my shoes and leapt into the back of the truck. Being the good slut that she is she reluctantly followed me, knowing full well she was in some serious trouble. “Face away from me” I said, pulling the handcuffs from behind one of the front seats and clamping them tightly around her wrists. “They’re a little tight” she said, pushing my rage even further. I pushed her head to the floor with her on her knees, forcing her ass into the air before grabbing her ankles and yanking her to the floor with a thump. She let out a gasp in pain from the fall “master I didn’t like that” she said as I began pulling down her pants and underwear to just below her ass. “This aught to teach you to tell me what to do and then complain about your punishments. I believe we were up to 10 slaps. You’re going to count them out for me.” I began slapping her ass hard from above her, one cheek, then the other. I could hear the light in her voice beginning to extinguish as it became more of a whimper. 8. 9. 10 she said through gritted teeth. “Now, are you quite finished complaining?”. She replied with only a nod. 17 minutes remaining.

Unbeknownst to her I had released my cock from my sweatpants, having had the excellent idea to go commando, and been playing with myself the entire time I was slapping her. She had no idea how hard my cock was, and it was coming right for her. Without so much as a drip of lube, I maneuvered over top of her, slipping my cock between her cheeks and pushed. The yelp that came from her mouth was delightful. I continued pushing, feeling her hole stretch and gape to take me but to my surprise as I reached about half way, it opened. She wouldn’t admit it but she was begging for me to fill her ass. Feeling this I pulled back, slipping out of her again and pausing for a split second before re approaching. This time I didn’t hold back. My full wait pressing down on her my cock thrust deep into her ass, another yelp, until my crotch lay resting on her now warm and red ass cheeks. Not a sound came from her mouth after this, as I thrust away. I said to her “I’m surprised you aren’t crying out in pain anymore” as she replied, in a shaky high pitched tone “I’m holding my breath so as not to scream”. “That’s a shame” I said “it wouldn’t matter anyway seeing as nobody would come to assist the cries of a slut like you”. Now all that could be hers was the sound of my crotch slapping against her ass and the occasional whimper from her. Eventually her innocent sounds got the better of me and I released, filling her ass with my fresh, heated cum. 11 minutes remaining.

I had expected for the rage to release with my load, but it did not. Whilst she was still panting, her ass gaping and raw in front of me I cleaned myself and snapped a few pictures. Reaching into the pocket of the front seats again I pulled out the second largest butt plug I have and said “relax and this will be a lot easier”, not giving her any idea of what was about to happen. With only my cum for lube I slid the but plug in gently, making sure it went all the way in. It barely fit and I could see her ass still pulsating, trying to reject it. She won the battle and kept it in like a well behaved little play thing, as I released her wrists from the cuffs. “Clean yourself and get back in the front”. Slowly she sorted herself out, groaning as she sat down in the front seat, the elongated plug forcing its way deep inside her. “You’re going to keep that inside of you until you get home, then I expect a picture before you take it out, and once you have taken it out”. She nodded, silently. 9 minutes remaining.

Not a single word was exchanged on the way back to the parking lot. I could see the pain she was in when she tried to jump out of the truck, it was so satisfying seeing her get what she deserved after trying to boss me around and fight back against her punishments. She turned around and looked me in the eyes, only her shaking voice betraying her “thank you master”. I did indeed make it to work on time, and promptly after her arrival home I received those two pictures. I still enjoy them from time to time when I don’t have her with me to use.
