Three years ago on a trip to San Francisco with her sister, Karen and Kathy had lunch, took the boat out to explore Alcatraz, explored Alcatraz, and were headed back to the Pier. There was a bathroom on the boat, but Karen and Kathy knew they were going back to the hotel so they weren’t planning to use it. But when the docking took much longer than expected, Karen felt the pressure of the Diet Pepsi from lunch pushing on her bladder. As the boat crashed against the dock, Karen felt a strong urge to pee. Karen shot a glance at the bathrooms on the ship, but her sister was already in line to get off the boat. Karen reluctantly joined her.

After the line finally moved and they stepped off the ship it was her sister Kathy who spoke up. “Karen, I was going to wait until we got back to the hotel, but I think I should use the restroom on the Pier.”

Karen agreed and the two made their way past the noisy Sea Lions and towards the Pier restrooms. To Kathy and Karen’s horror, the doors were locked.

Karen had been wetting herself for fun back at college, and suddenly had a devious thought cross her mind. What if I just wet my pants right now in front of my sister? Karen grinned, but before she could think about putting her plan into action, her sister Kathy was scurrying back across the food court towards the road.

“Karen, let’s just get a taxi and head back.”

As they sat in the taxi, Karen felt another spasm. It would be so easy to pee herself. She would have plenty of excuses. But Karen couldn’t do it.

Karen now found herself sitting on a bench at the mall watching Kathy’s kids play on the mini-playground. Off in the corner, a little boy was having his diaper changed while standing up.

“Ughh, look at that,” Kathy said with disgust. “If a boy can stand there and help get his own diaper changed, I’d think she could be toilet training him.”

Karen didn’t know how to respond.

Kathy continued. “Actually, I’m pretty impressed she can do that standing up. It seems like it would be pretty hard to put a diaper on someone while they are standing up.”

Karen just grinned. She was well prepared to put on a diaper whether sitting down or standing up. But not today. Karen’s mind continued to wander. Could she wet her pants? No, it would have to be something close to a real accident, and that just wasn’t going to happen. But what else could she do to have fun with her sister?

Kathy spoke again. “I’ve been thinking of joining a gym. I just can’t seem to lose any weight from these darn kids. Do you want to join me and maybe we could be exercise buddies?”

Karen started contemplating what sorts of fun she could have at the gym. Maybe this was just the place to get a reaction out of her sister. But how?
