I couldn't believe my luck. Here I was, working my shit job at the mall, fixing some wiring in the ladies room. I stood on scaffolds, reaching up into the hole left by removed ceiling tile. Keeping your arms above your head for long minutes is tiring so I kept dropping them to my side for short breaks.
About the fourth or fifth time I did this, almost done,  I leaned back against the scaffold, still standing but closing my eyes for a short break.
After a minute or two, I heard some laughing and talking. No big deal, the mall is full of teenage girls.

What turned out different here was I heard one say "oh so what?! No one will notice" as she walked into the rest room. Obviously, she was ignoring the "restroom closed" sign. I was about to say something but didn't want to scare her as it became clear she didn't even notice I was standing about six or seven feet above her head.  

I guess what made me pause was how hot this little chick looked: short dark hair that curled beneath her chin and a sweet baby fat body and cheeky cute face, a splash of freckles across her nose.

From where I stood I could see the swell of her young hips, maybe thirteen years old or so but especially I could look right down into her ample cleavage, big tits for such a young girl. And dressed a little too slutty for a little girl: low cut strappy thin top that clung to her adolescent body and tied at the waist, showing her stomach like all the girls do these days. I love those little girl chubby stomachs, pooching over their waistlines with no self-consciousness.  My dick was getting hard, me taking all this in, in only a few seconds. 

It got rock fucking hard when I watched this little girl, with a ripe fuckable jailbait body, untie the knot in her shirt and pull it over her head, allowing those big titties to bounce into place, still held by a filmy bra, obviously stretched time and again over her developed rack and showing signs of wear that also showed her flesh through the cloth.

She tossed the shirt on the counter and filled her hands with her tits, a B cup I'd say, maybe 32. She shifted them around, trying to get `em comfortable. Seeing such a little girl (one with a great rack!) holding and playing with her own jugs was too much. I began to rub my cock through my pants.

When with a sigh she reached behind her and quickly yanked off the bra too, I couldn't resist but actually pulled out my dick and silently pulled it, trying not to breath hard.

Free from the tight bra, her magnificent adolescent titties bounced free, nipples hard and dark. She stood, just looking at herself in the mirror, turning this way and that which gave me great views.

I knew this was a stupid thing for me to do, jerking off while checking out a little girl but if I could've I'd have boned the little bitch right then and there!

"hey shut up" she said as one of her friends called something to her from outside the door. "hang on willya? This thing is messed up", I guessed she meant her bra.

Still looking at herself, she raised her arms over her head, pulling her fat jugs up and displaying for me some dark curly hair under her arms. She hasn't shaved yet or hadn't recently at least.

I pulled my throbbing dick faster. Like I said, I can't believe my luck because this little girl turned on the water to wash her hands and splash a little water on her face.

She shook her hands to flick off the water and that made her huge-for- a -thirteen-year-old titties shake too. That did it. With the water still  running and hissing, I jacked harder on my dick, knowing she couldn't hear me now. 

A spurt of come shot out of my cock and just as it did, she twirled her head to again say to her heckling friends "be right there!".
That first rope of jizz  was timed just right because it hit her hair as she turned about so she didn't feel it. 

As I kept jerking off at this thirteen year old, I also kept jerking off on to her. Another little wad hit the back of her leg which she must've thought was a splash of the running water because she started a bit, further making her nice big tits bounce, then shut the faucet.

More drops of come, jerked off while spying on a hot little thirteen year old girl, went directly into the bra on the counter just before she grabbed it and swung it around over her big but firm titties. "aw fuck" she said realizing the wetness but still not getting it, probably thinking it was again a splash of water. She pulled her shirt back over her head. 
As her friends called her once more, she spun around just barely in time to catch my last few drops on the ass of her shorts and walked out of the bathroom.

 As I stood there on the scaffold, dick still in hand, the thought of a baby fat big titted thirteen year old girl parading around the mall with my come in her hair, on her leg and in between a tit and bra kept me hard. 
Sooner or later her friends would notice. So I finished my job and cleaned up as quickly as possible and darted out. Looking around, she was nowhere in sight so I sat down on a bench, waiting.

Sure enough, soon , as all girlie mall rats do, she passed by with her friends. I could see a rope of silvery come in her dark hair and just a slight wetness at her nipple. I smiled to myself as they passed.
A few seconds later, the girl behind her, a hot little skinny blonde with budding titties (of course I'd just checked her out too) cried "ewwww! Alison! gross!"

I knew what she had just noticed.
