Denied Than Exposed

GF and myself went out to celebrate her promotion at work. After drinking a lil and celebrating we went back home she was in a happy very hands on mood and of course I was horny and wanted more. I asked my Domme for permission to cum if gf and me have sex she told me no I must deny. I tried making it all about her fingering her sucking her clit even fucking her with strapon. I was hoping she was wore out and wouldnt want to pleasure me so I didnt have to fake an orgasm and deny. She told me now its my turn to make you cum and she would of made me cum 4 times if I didnt fake it for her to stop. Im a dripping horny mess at this point. My GF said she was going to shower than go to her friends so I was free to text my domme and tell her what happened. She made me get dressed tank top no bra and booty shorts no pockets or panties, bring a suction dildo with me. Had to go to a gas station and buy a soda than find a parking lot to park in. With no pockets i had to put the cash over my nipple under tank, keys hanging off back of shorts pulling down, phone clipped to front of shorts pulling them down. I was not allowed to pull shorts up once i left my car. I had to take the money out by pulling my shirt down not lifting money out, showing my hard nipple to cashier my shorts were low showing my stomach V and ass crack. After getting back in my car my shirt was pilled down so nipples were exposed as I drove to a parking lot. Once there during day stripped naked and made to suck dildo as I rubbed my clit. Edging over and over again started laying soen in back seat than sitting up than in driver seat and last on all 4 knees on front seat hand on back ass up facing windshield. She denied me over and over and made me drive home nude exposef humiliated and denied.
