Since the elevator incident, Lori and Erica had been wondering how long it would take to run into another woman interested in enjoying their games with them. They didn't realize it yet, but they wouldn't need to wait very long.
They had enjoyed their summer, holding as often as they could, both bladder and bowels, and Nora had joined them multiple times in their adventures. When summer finally ended, they had enjoyed themselves so much that they didn't want it to end.
Summer did eventually end though, and the girls had to get back to school for the beginning of their sophomore year. They had signed up for classes at the appropriate time, making sure to match their schedules as closely as possible so they could continue their fun, and their growing relationship.
By the end of week one, they were back to holding games, often trying to get as desperate as they could without being too obvious, then coming back to the dorm together and often having nearly unavoidable accidents. They became experts in cleaning up without anyone noticing, so there was no real risk of discovery. The one thing Lori noticed was that one of their core class assistant professors wasn't very much older than the two of them, and was extremely attractive. She mentioned it one day over lunch to Erica, who agreed wholeheartedly. What happened next, they couldn't have planned if they tried.
At the beginning of week two, Lori and Erica had gone into the school day with full bladders. They had survived their first class just fine, then went to their second class with the attractive young assistant professor. As they entered class and sat at the back to conceal their full bladders, they noticed the assistant professor, Anna if they recalled, cross her legs somewhat noticeably, and the obvious question came up in both girls' minds at once, why was she crossing her legs this early in the day? Was she a holder? They quietly discussed it before class started, and decided to start keeping an eye on her as this class went on, and develop a pattern throughout the week.
As the class went on, it was becoming increasingly obvious that Anna at least had to pee. She was showing no overt signs of a need to poop, but they both knew how easy it could be to conceal desperation from the unaware public. But Lori and Erica were not unaware, not by a long shot. As the hour ended, the girls decided that Anna was definitely a holder, as she was clearly somewhat desperate, but didn't rush for the door to find a bathroom. The girls held their pee the rest of the day and soaked their panties on the toilet in a single stall one at a time that afternoon. Neither had to poop yet, but it was simply too early in the week for that need to develop.
The next day in the same class, both girls had to pee again, and both were squirming slightly but trying not to show it. They immediately looked for Anna, and found her walking around consulting with various students about an assignment from the week before. As she stopped at the next student, Lori and Erica watched intently to her demeanor. She immediately crossed her legs the moment she stopped moving, and seemed to wince just slightly before assuming a comfortable posture as if nothing was wrong. She was definitely holding, but it was unclear as yet whether she was holding in her bladder, bowels or both. Any other person might have made an excuse and disappeared to a bathroom as obvious as her desperation seemed to be, but she kept on walking around answering questions until class started, then assumed her position at the desk in the front of the classroom, assisting the professor as needed.
As class went on, Lori and Erica kept a careful eye on Anna, trying to gauge how desperate she really was, and whether she was holding more than just pee. As the minutes ticked by, it became obvious that Anna was visibly desperate, shifting and crossing her legs from time to time, and once when the class was supposed to be heads down reading a section of the textbook, grabbed her crotch discreetly under her skirt. It was obvious she was bursting, and trying to prolong the inevitable. At one point, Lori detected something else as she was fighting the fullness in her own bladder. She noticed Anna wiggling her ass side to side in her seat, then she heard what sounded like the chair scraping on the floor. A moment later Anna put her hand to her belly, and Lori realized that what she had heard was a booming fart from Anna's full bowels. She whispered to Erica to watch for more signs of bowel desperation from Anna, which she did. Of course as they were both focused on Anna's full bowels, they both started realizing their own were getting quite full, but they'd hold it and come up with a plan for tomorrow.
As class ended, Anna stayed behind and once again didn't rush for a bathroom, despite how desperate it appeared she was. The girls looked right at her as they were walking out and both gave her a seductive smile, which she instantly returned just before they walked out the door. They discussed it as they left, and realized they'd have to approach her tomorrow hoping she was still holding, as they would be. They just had to figure out how they'd do it in a way that got Anna to join their fun.
The girls finished their day with one more class, then went back to their room, both masturbating to their full bladders for a while until they couldn't hold it anymore. Then they both rushed to the bathroom, sat down on toilets next to each other and exploded into the bowls for almost two minutes each. They struggled to hold their bowels the whole time, but they managed in the end, and realized they wouldn't be able to hold their pee as long with their bowels so full and would have to focus on mostly just holding their loads going into tomorrow.
The girls had discussed the night before how they would approach Anna. They only had two classes, and they suspected Anna was only attached to maybe a couple classes in a given week. They would desperately hold their bowels through class, and maybe their bladders if things worked out that way. Then they would wait until class ended to approach Anna with a classwork question, concealing their true intent until they were out of earshot of everyone else exiting the room as well as the professor. They would ask if Anna wanted to continue to hold everything in, then meet them in their dorm after her last class, whenever that was. The girls agreed they couldn't plan it any better, so they decided they were ready to put their plan in action.
The next morning, Lori and Erica woke up bursting to poop. They knew they could hold it at least until this afternoon, but it was going to become increasingly difficult to prevent people from seeing their desperation. They were going to do their best to conceal it anyway as Nora had taught them, but it would eventually become obvious no matter how hard they tried to prevent it.
The girls went to breakfast before their first class, peeing before they did. They continued to review their plan for engaging with Anna. The more they discussed it, the more exciting the idea became, and the more aroused they were thinking about convincing Anna to hold it longer. She was extremely attractive, clearly had a love of holding, and there was a good chance she didn't have anyone to safely share her secret with. It could be the start of a great friendship, and the girls were set on this being the day it started.
Lori and Erica survived their first class with their full bowels, discussing more about Anna, specifically how they'd need to keep an eye out for desperation signs, especially those indicating she had still not emptied her bowels. It was agreed they would quietly share everything they saw, and make a determination of what to say before class ended so the conversation wasn't awkward. About this time, both realized their bladders were filling at a steady pace, and would soon be a major factor.
They finally ended their first class and walked uncomfortably to their next class, looking for Anna as they sat down in the back to contain their imminent bowel movements and still-filling bladders. Today Anna was at her desk, looking over some papers, almost unaware of anything around her it seemed, though she seemed to feel Lori and Erica staring at her, and briefly looked up to meet smiles from both with a tense one of her own. Lori whispered to Erica, "She's definitely gotta go, what do you think?"
Erica, noticing Anna's slight foot tapping, how tightly her legs seemed to be pressed together, and the shallow and tense breathing she seemed to be doing, said, "Yeah, I'm pretty sure our girl is holding both."
They watched as she briefly stood up just before class started to answer a question one-on-one with a student in the front row, and as she stood up and walked to the student's seat, both girls could see she was stand completely vertically looking as if she was tied to a plank. Lori whispered to Erica, "Look at how she's standing. No one stands that straight up unless they are actively clenching against a desperate dump."
Erica said with a smile, "I totally agree. Couldn't be more obvious."
