Sarah is surprised by the girl

Sarah opened the door, and with a smile on her face greeted the delivery girl, who was holding her parcel in front of her.
The girl wasn't very well endowed in the chest department, but more than made up for it with a cute body and slim figure.

"Oh, hello there! Sorry to keep you waiting."
"Hi! No problem! I have a express delivery for... Sarah i presume?"
"That's correct!
"So Sarah, where can i put down the package?"
"Just come inside, you can put it over there?"
"Sure!"

But when the girl stepped inside, Sarah was surprised and discovered that the parcel was not the only package that the delivery girl had brought with her:
Her hot pants were strained to the maximum to contain a sizable dick and balls.

Not even nearly as big as Sarah's own bulge, but still enough to awaken all kind of sexual desires inside of her.
And while Sarah still had to process this new information, that she apparently wasn't the only dick girl around, or even the first to discover the potential of the "Growth X" pills,
the UPS delivery girl equally had her eyes fixed on the straining bulge in Sarah's shorts.
