NO ENTERING! BLOWJOBS ALLOWED! Skinny girl turned into a thr

While I'm out walking, I spot a skinny teen girl at a construction site and it seems as if she's looking for something. Brash as I am, I simply pretend to be a construction site worker and talk to her. When I tell her that no entry to the construction site is allowed, she's totally shocked. I just tell her that I have to call the public order office now or we can sort it out somehow. She willingly follows me under a bridge and I just take out my cock. She doesn't seem to be averse to it and immediately kneels down and starts to blow my cock. She blows my cock deeper and deeper and even lets me deepthroat her hot, tight mouth. During the blowjob, she drools a little, but that just makes me hornier. I fuck her harder and harder in the mouth until I squirt my cum into her mouth. But instead of swallowing my hot, load of cum, she spits it on the floor and runs away in disgust. What was wrong with this bitch? Is she allergic to cum or does she just not like swallowing?
