Go swimming

"Hey, it's pretty good weather today. Why don't we go to the public swimming pool?" I was hoping to see some sexy girls in their bikinis, so I was glad when Gina happily agreed.
Gina packed her things and we quickly drove by my place to get my things before going to the public pool.

When we arrived there was no line at the entrance so we managed to get in fast and made our way to the changing rooms.
"See you in a few", Gina said and entered a changing room. I walked down the line of changing rooms until I found one that was empty and walked in, locking the door behind me.
I started undressing, first pulling my shirt over my top, then taking off my shoes and socks and lastly dropping my pants and boxers. Standing in the changing room naked, I heard the handle of the door being pushed down and turned around saying "Occupied, sor-". Before I could finish what I was saying the door opened and a girl came in, quickly closing the door behind her. I couldn't form any complete words, as I was still shocked by the doorlock apparently being busted and the sudden person right in front of me. The girl turned around and looked at me, just as surprised as I was. She was small with long blond hair, tied up in a ponytail and she wore a tank topand a long skirt.

"Oh!", she finally spoke up. "I am so sorry! The lock must be broken!"
"Yeah, I guess, because I definitely locked the door." After I noticed the girl looking straigth at my dick, I remembered that I was completely naked and tried to hide my dick with my hands. The girl on the other hand seemed to have no intention to leave, instead she even moved closer to me.
"Okay, since I just busted in here so rudely, I'm gonna make it up to you."
"What? How? Can't you just leave?"
"No. I'm a slut and you got a huge dick so I'm gonna give you a blowjob, right now."

That took me so much by surprise that I didn't even stop here when she kneeled down and moved my hands away from my dick, which was now quickly getting hard. She started playing around with it, stroking it slowly and licking it. Now I just didn't care anymore, this girl knew what she was doing, it already felt good.
After she got my cock hard as can be, she took it in her mouth and slowly pushed herself down my long rod. She managed to get all of it in her mouth and didn't even gag. Then she moved back and let my dick slide out of her throat, but quickly took it in again, going faster than before, but still taking all of it in. I kept my mouth shut as good as I could, not wanting to let any moans escape and get me in trouble.
Now the girl was really going at it. She gave me one hell of a blowjob. I put my hand on her head and pushed her down hard everytime she took my cock in her slut mouth. It didn't take long for me to reach my climax and I tapped her on the head to get her attention "Cumming!", I managed to let out. She just winked at me and grabbed on to my ass, as she took the whole length of my dick in her mouth again.
I couldn't hold it anymore and came down her throat. It was an amazing feeling. Standing in the changing room of the public swimming pool, cumming down a stranger's throat. The girl pumped every last bit of my cum out and then licked my dick clean, before getting up.

"Well, that was fun, we should do that again sometime", she said and left. And I was just left there, wondering if I maybe just bonked my head and dreamed all that.
