You know exactly what's happening!

With a start you lunge away from the wall, his african anaconda snaking out of your bright pink pussy just in time to coat your milky white bubble butt with four or five long ropes of thick, unhealthy looking yellowish semen.

He was going to cum inside of you if you hadn't stopped him, he was going to try and add you to his list of baby mommas. Shuddering, whether from the empty space in your previously occupied and now sadly empty pussy, or from how close you were to destruction, you know that now's the time to leave.

Grabbing your shorts from the hook on the wall and pulling them back up, frowning as you feel your wet ass cheeks coated in seed stick to the inside of the shorts, you watch his length recede into the wall....

Only to be replaced by another throbbing black cock. Was this sex shop connected to a fucking basketball court or something?

You're not averse to a repeat performance; you didn't cum and your pussy is aching for it. But it really couldn't be healthy, fucking dirty anonymous strangers on the bad side of town. Getting pregnant was only one worry, a massive worry, but it's not like he wanted to change back into a guy and have herpes either. But on the third hand, there was something about the taboo, the risk, and the absolute sexual thrill of feeling her upper middle class white teenage ass bounce up and down on the frothing fuckstick of someone who was probably a janitor at the place her parents worked.
