You and your girlfriend, Sunshine, are in the backseat of an Uber, and you're both in a terrible need to urinate. She's been wriggling in front of you, and now she's finally said so! It was really hot to hear her utter such foul language, including SH-- and urine. Clench! You start losing control and wetting your trousers and pushing out a large load in the back since you can't hold your bladder and intestines in for very long! She remarks about how awful the scent is, hoping the driver won't notice. She loses control of her front and backside after witnessing you lose control, and now she's sitting in a puddle of her own urine! She can feel it leaking and torturing out of her underwear, which is disgusting. It had to be something you both consumed. She's astonished but not repulsed as you sprint from the car to the front door, but you have to tell her the truth because you're so turned on!
