Nora started sharing her initial introduction to desperation at about 16, nearly 17. At the time, she'd said, she tried to shut those feelings down, worried it would make her weird. A little over a year later though, on her 18th birthday, things had changed, and that was when she considered herself truly awakened to her desire to be desperate for a bathroom, and the arousal she gained from the feeling. Lori and Erica listened, as attentive as either of them had ever been.
Nora, attractive by most standards, with a nearly perfectly proportioned body, had woken up that morning of her birthday, realizing she was now an adult. She also woke up with a slight need to pee, but that morning, she was feeling differently about it. Instead of trying to shut her feelings off, she felt herself inviting them, and decided to wait a little longer before she had her morning pee. She wasn't sure what had changed, she just felt like she should just be herself today now that she was legally an adult.
She rose from her bed, went to her bathroom to shower, and skipped the toilet to have her breakfast. The juice with her eggs wouldn't help, but she was not going to let that intrude on her enjoyment of living in the moment. She kept holding it all the way until it was time to leave for school. Even in her time, seniors could drive themselves, so she got in her car a few minutes later, still holding a semi-full bladder. It wasn't that full though, so she could likely hold it for a while longer.
As she started her classes for the day, her bladder wasn't necessarily that full, and it wasn't really arousing her, Nora was just enjoying the slight fullness that was very slowly building throughout the morning. Her first classes went smoothly, but by lunch her bladder was getting progressively more full. It was getting full enough that she started wondering when she'd end this game, but it was also starting to cause feelings of distinct arousal, and she could feel her lady parts tingling the more full she became. The answer was she'd hold it as long as it didn't become a real problem.
Nora ate her lunch, enjoying how full her bladder was getting, and drinking only enough to stay reasonably hydrated and awake through the rest of the day. When lunch finally ended, she found she was jiggling her legs a little bit as the need grew a little more intense. Her next classes went by a little more slowly, as she was focused a little more intently on her bladder and making sure she didn't piss herself.
As her last classes came and went, Nora was feeling a bit more uncomfortable, her bladder feeling quite full, the need to pee getting very urgent. She was within sight of the end of the school day though, so she forced herself to keep on holding, enjoying the added arousal she was getting the fuller her bladder became. It seemed that the more her bladder grew, the more it intensified the feelings in her lady parts, and she was having a hard time not touching herself in her last class.
Finally, the school day ended, and she drove home, not quite wanting the game to end, but realizing she needed to go pee soon before she wet herself. When she got home, her parents had immediately told her they were taking her to dinner for her birthday in about an hour, then having cake. It was then Nora realized she had a decision to make. Would she go now, wait and go before dinner, or try to hold it through dinner?
She thought about it, and realized she was truly enjoying the challenge, and couldn't see ending it too soon. She waited until they were about to leave, then walked to the car, still bursting and thinking, "I guess I'll just need to hold it for now!"
Dinner was difficult to endure with her bladder so desperately full, but she did her best to conceal her urgent need from her parents. No one seemed to notice she was bursting. The reality was that she was now so aroused, it was taking all her willpower not to grab her crotch to hold in her pee, because she knew if she did, she'd start masturbating subconsciously.
Nora somehow made it to the end of dinner, and got home thanking her lucky stars for the relative darkness of the backseat of her mom's car, because she had to grab her pussy and squeeze herself to keep from flooding her panties now, and just the act of squeezing there to prevent a flood was getting her wet.
When they made it home, Nora forced herself to remain composed despite her bladder's desperate cries for relief and only leaked a little in her panties as she blew out the candles on her cake. She made an excuse after a small sliver of cake that she needed to lay down in her room and assured her parents she was just fine. The reality was that Nora was likely minutes away from pissing herself uncontrollably if she didn't do something right away. She laid down on her bed, feeling her bladder with her hand bulging out from her normally flat abs, and instantly had a thought. Could she hold it if she masturbated like this?
Without a further thought she started touching, then rubbing herself, her bladder throbbing, her womanhood on fire, her bladder and her pussy both screaming for their needs to be met. A couple agonizing minutes of stifling moans, whimpering and screaming, and she had a mind-numbing orgasm, somehow not pissing her panties and bed in the process. She instantly squeezed her pussy, groaning as her bladder now tried to force a release. She got to her feet, dancing a moment frantically at her bedroom door making sure the hallway was clear, then bolted to the bathroom, slammed the lock closed, and threw herself on the toilet as her pee started spraying through her panties before she was even seated. She peed for nearly two minutes, soaking the toilet seat on her way onto it, and had multiple orgasms as her throbbing bladder finally got its relief.
It made Nora incredibly aroused just retelling the story, which Lori and Erica could easily tell. "Holy hell mom, that was incredible! That's such a hot story! I love it! And dad never knew about that?"
"God no, he'd lose his damn mind if he realized his wife was such a freak." She chuckled, but Lori assured her she was anything but a freak. She did have one more question though.
"Mom, when did you realize it was the same story when you had to poo?"
Nora smiled and blushed, remembering how she'd experimented with holding her bowel movements, but said she never got so desperate as to risk an accident... at first.
It was a few months later when she realized that holding her poop could generate a similar effect. So, one day she planned a hold that would really put that to the test. She'd gone poo on Friday before school, then held it through the weekend with some difficulty. She woke up Monday morning with a pretty urgent need to poop. She'd showered, peed carefully, and eaten breakfast which was sure to bite her later.
She drove herself to school then, having skipped her home bathroom to release her bowels, and told herself she couldn't poop at school no matter what. She told herself a story that all the bathrooms were out of order, and she had no choice but to wait until she got back to her home toilet to empty her bowels.
Her first classes were a struggle, with her poop pressing hard against her tight asshole. The pressure was unreal, and a few times built up so much that she had to fart quietly to make herself more comfortable, which someone always blamed on one of the guys in class. No one knew Nora was holding in the most urgent shit of her whole young life.
