Michelle took a deep breath. "Panicking is not going to help me at all", remembering the motto someone had written on the blackboard of her old high school homeroom. "First, I need to take care of this." With that, she put one hand on her boner.
To her surprise, it actually felt...good. She started moving her hand up and down, making her dick even stiffer and longer. The more she stroked, the happier she became. Eventually, her dick twitched, and in the span of just a few seconds, a big load of semen came spraying out and splattered all over the bathroom mirror. Michelle got some on her finger and tasted it.
"So that what cum tastes like, huh?" Suddenly, she grabbed her softening dick and stroked it until it was hard again. When she came, her semen was more watery, but it still shot out in a fierce stream and covered the wall.
Jeff knocked on the door. "Michelle, you're grunting. Is something wrong?"
"No, I...just need to pee." Michelle stood over the toilet and for the first time, peed while standing up. It was unfamiliar to her, and she wound up getting just as much urine on the floor as got into the bowl, but she managed to finish. With that, her cock quickly softened. Michelle noted that, even deflated, it still stood at a good six to seven inches. She took pride in the size of her package and put her panties and jeans back on, leaving a noticeable bulge on the front of her pants.
Walking out, she found Jeff changing his own pants. When he turned around, she noticed that his own cock was gone. Instead, he had a vagina with a shaven bit of hair around it.
"You want to switch?"
Jeff gave Michelle his boxers, and she handed over her panties. Once the two had put on the appropriate undergarments, they discussed what they were going to do for the rest of the day. Jeff said he was thinking about making dinner for them that evening, and then maybe buying something to stream afterwards.
"So, are you saying you want to have a date?"
"Yeah, pretty much. And if it goes well..."
