Driving with my friend down bumpy roads with my vibrator in my pants. My friend finds out I had a toy in my pants and went down roads that are more bumpy to see how much sensation I could really handle. I am seen in the passenger seat holding on tight and trying not to pee my pants at the same time im trying to cum. I get dropped off at home and I'm locked out of my house and have to desperately pee. I have no other choice but to go pee, even while my neighbors are outside. But I still pee in my jeans and I feel so relieved.
