I had been seeing this woman off and on for a few months. Neither of us were exclusive but one thing I liked about her beyond the aggressive and relentless fucking when we were together was her getting tested, we showed each other recent tests just before this concert.

I got tickets to a concert by a local cover band that did 80's rock really well. It was at a venue that was sro, and it had a space in front of the stage, then about 25 feet back a raised space with a railing. We were at the railing, her in front of me pressed together. We'd already licked each other's tonsils and gotten pretty handsy before the band started. When they were playing she was gyrating her ass against my crotch which got my member swollen. She was wearing a thin white blouse and a red pleated cheerleader-like skirt, and like me, she was commando.

About 1/2 hour in she turned, kissed me and with one hand unzipped and pulled my partly swollen shaft out and stroked me, which got me hard fast, then turned back leaving my now-rigid cock pinned between my stomach and her back and ass.

The crowd around us was pressed quite tight and watching the band, and no one seemed to notice what we were doing.

I lifted her skirt and pushed my dick under it, and slowly thrusted between her thighs. She pulled out a tube of face cream from her small pack and handed it to me, which I put under her skirt and squirted it on my dick. I dropped the tube, grabbed her hips, pulling her ass cheeks apart and pushed my aching shaft in her ass, driving in deep. Her skirt was draped over my cock so not only did I feel inside her but I had the sensation of fabric caressing my dick as I thrust. She twisted and gyrated more, making small shrieking sounds which were lost in the music and fans shouting. One of the plusses having a huge dick is being able to fuck in positions like this, to get deep inside her and to still being able to see my face-cream shiny veined cock sticking out of my jeans and sliding in and out under her skirt. Nobody around us seemed to notice but it added to the heat of the moment that I was ass-fucking her with people pressed against either side of us.

After several minutes of both of us thrusting/gyrating against the other she stiffened, then shook, her whole body writhing, having an orgasm. That pushed me over, I rammed as deep inside her as I could, and in the middle of all the cacaphony of sound my shout was lost as I pumped my nuts into her colon.

At this moment I was spent and a bit weak legged. I wanted to stay inside her until I got softer knowing I couldn't serruptitiously put my full erection back in my pants without unbuckling etc. which could be noticed. She started gyrating and dancing against me to the music again, which I swear made me harder and moments later I came again, pumping another load into her, thrusting so hard and deep she was on her toes.

I stayed inside her, I wanted a third time and ached, throbbed, consumed by the need to pump out another one. But at a music pause she turned and said in my ear she was getting uncomfortable.

I quick unbuckled and pulled out, stuffing my hard dick back in regardless if someone saw, then buttoning up. Good thing I went commando too. No one noticed my big dick print thru my jeans and it subsided shortly.

We enjoyed the rest of the concert then decided to go to a bar for drinks. In the car she used a towel I had in there to wipe off my cum running down her legs. Than got me aroused again but she repeated she was a bit sore from the concert fuck, and she liked being stretched and filled and probed deep, she wasn't used to my size wanted to take it easy, but she didn't leave me hanging. Or bulging lol. After she used a wetwipe to clean off my shaft, I got a hand job in the car while parked outside the bar, which included her slurping the cum off my cock.
