Trapped in a crawl space with a useless invention?

Charity was hired by a mystery man to steal the portal gun. He explained to her that the gun opens a portal she could pass through; she understood that this would make stealing, so much easier. The crawl space she was in had no clear exit so she tried to use the portal gun to create an exit. She zapped the ceiling and she couldn’t get through it, so she shot the floor and could go through, but now she noticed a woman’s legs above her; as she stood up to crawl through the opening she realized that she was crawling into the same space. She sat pissed for a few minutes when she realized that she could entertain herself using the portals. She crawled up and started pulling her pants down she started licking her pussy and working her clit, and as she move to insert her fingers in her snatch she could feel her orgasm build.
