When the cab got to his house Jeff managed to get out of the house without his sister seeing him. He gave the driver the destination and then sat back to enjoy the ride.
---------------
What Jeff did not know was Nikki happened to find the device at that same time. She looked it over a bit as she tried to figure out what it did.
Not being able to figure it out and having to get ready for the contest she put the strange device back into her purse, but she happened to hit a few buttons in doing so.

Back in the cab Jeff started to feel very hot as her body began to tingle.
Without thinking she brought one of her hands to her breast and started to squeeze it while the other hand went to her now very wet pussy as she started to finger herself.
Jeff was so into pleasing herself she did not notice the cab driver pulling off the main road to a secluded area. It was only when the door to the cab opened and the driver got into the back with her that she noticed but by then she was so far gone that she did not resist as the driver started making out with her.
It was not long before she was naked and riding the driver's dick as he was playing with her breasts.
The two of them went at it for quite some time with the driver giving Jeff a number of orgasms.
When they were finished .........
