You continue to pump cum into Gracie once you've finally ejaculated inside her with your massive penis, which made her own stomach inflate in front of you, while you were still on the bed, and fucking her senselessly without a thought. This was an experiment you haven't been expecting in a while.
You pull out by the time your cum balloon was entirely full, and see Gracie's face completely satisfied with the smile of someone who enjoyed having something shoved in their pussy for a very long time as she was also holding the money you earned for fucking her. After shrinking your penis back into a pussy you took the money. With the money you obtained, you place it in your purse, and then put your clothes back on, while heading outside, and heading back to the HQ you worked at.
