Lori was so turned on by Erica's boldness as they both emptied their full bladders, she stared in Erica's eyes, and they started kissing as the pee was cascading out of both their full bladders. When it finally ended, Erica felt her asshole open, but she quietly squeezed it shut preventing her poop from coming out and hiding her need from Lori for the moment, realizing she couldn't do that forever.
They returned to the living room in pajamas and decided to watch a movie with Lori's parents where they snuggled on the couch together. Nora noticed how unusually close the girls were, and realized why, and it brought a smile to her face that Lori noticed and returned.
As they watched the movie, Erica thought about her bowels, which were getting fuller the longer she ignored her need. She'd need to poop eventually, but she was nervous about pooping in Lori's house, especially since Lori would likely hear her going. Erica was always a bit embarrassed about anyone hearing or knowing she was pooping, sometimes holding it in desperation throughout high school rather than risk anyone getting the idea that she was having a stinky bowel movement. Now, with the intimate nature of her relationship with Lori, she was extremely nervous about Lori being aware of her need and possibly having to hear or smell her emptying her bowels. She'd just need to hold it in until she could find the right time. Maybe Lori would need to go run an errand or something? Erica hoped that would be the case, because her bowels were feeling quite full already, and she wasn't entirely sure how long she'd be able to wait.
As the movie wrapped up, Lori and Erica got hugs from her parents before they went to bed, and Lori and Erica soon followed, brushing their teeth and peeing together. They got in Lori's bed, thankfully big enough for two, Lori in her usual booty shorts and t-shirt, Erica in panties and a t-shirt. They snuggled together as they fell asleep, while Erica thought again about the load knocking on her back door.
They woke up Thanksgiving morning, both needing to pee desperately. They laid in bed together just a little longer, enjoying the fullness in their bladders before going to Lori's bathroom to do their buddy pee again, kissing each other passionately as they emptied their very full bladders. Erica felt her poop pushing again and had to clench, which got Lori's attention this time. "Are you okay sweetheart?"
"Just a cramp," Erica lied, "I'm okay."
Lori suspected she already knew what was going on. She played it cool, kissed Erica, rubbed her tummy as a sign of affection and care, and said, "Okay, hope it doesn't get any worse."
Erica immediately thought, "Did Lori already know?" Did Lori already know she was holding in a bowel movement, too shy to go? Maybe, but she was playing it off, and so would Erica for now.
They showered together, got dressed in her bedroom admiring each other's bodies, and finally joined Lori's parents for breakfast. Nora had fixed eggs, turkey bacon, fresh fruit, and toast, since they'd be having a late Thanksgiving lunch. They could snack between the meals if needed, but Nora didn't want anyone to get starved in the meantime. Both girls ate plenty, despite Erica feeling her bowels begging for relief more and more. She'd continue to hold it, not wanting to embarrass herself.
After breakfast, the girls were invited to go shopping by Nora while her husband watched football and prepared the Thanksgiving meal. The girls agreed, and after peeing once more they all jumped in Nora's car and headed to the local mall to browse the shops that were still open until about noon. The entire time, Erica was hoping for an opportunity to relieve her bowels, but she never found a chance to sneak away. At one point she was thankful as Nora decided to sit down in the open area of the food court and asked about the new and adorable relationship between the girls. Lori, picking up on Erica's nerves, as well as the possibility that she was desperate to poop and was trying not to let anyone know, started doing most of the talking, with Erica filling in some details from time to time. Nora was so open-minded that she expressed nothing but love and adoration for the girls. It touched both of them, and they held hands at the table, looking into each other's eyes and smiling as Nora watched with the sweetest smile on her own face.
Finally, they left the mall, Erica still having been unable to sneak away to relieve her bowels. It wasn't super urgent yet, but it would likely get there before the end of the day. She just hoped she could find a chance to poop before it got really desperate.
When they got back home, the late lunch was nearly ready, and Lori suggested they set the table before it was. Erica helped her, feeling quite full and trying not to show it, but Lori could tell. She was so attracted to Erica she could tell when something was off, and she seemed awfully tense. It was about this time that Lori felt her own bowels starting to get full as she was on day two without pooping. She made a quick decision as she felt the urge building that she'd hold it in support of Erica, hoping she'd notice Lori's urgency too.
They finished setting the table, and as they were about to help get the food, Lori thought she smelled a fart, glanced at Erica, and she was blushing. It couldn't have been more obvious what was wrong, but Lori mildly enjoyed watching Erica try to unsuccessfully hide how badly she needed to poop.
As they sat down to lunch, Lori's dad said he was thankful for good company for Thanksgiving. Nora said she was thankful to have her darling daughter and equally darling friend for a lovely Thanksgiving. She said "friend" with a slight tone that made both Lori and Erica blush. Both said they were thankful for each other, and Erica thanked Lori's parents for the touching hospitality. They all proceeded to eat well, including Erica, despite the urges from her bowels. After all, she didn't want to be rude by not eating.
When lunch was finished, Lori and Erica helped clean up. Erica was looking a bit uncomfortable, but hadn't said anything. Lori was starting to feel a bit more urgency from her bowels, but wanted to keep holding it until Erica started feeling comfortable enough to express her need, just so she could put Erica more at ease with her own need.
About this time, as Nora was doing the dishes, she started feeling some pressure in her own bowels, and knew she'd need to poop soon, likely tomorrow morning if not sooner. Thanksgiving always made for an extremely large bowel movement for her. The secret she never really shared with anyone, including her husband, was that she actually enjoyed holding in her poop, and had since she was a kid. It got her quietly aroused when she felt that pressure start building in her bowels, then as it started moving to fill her rectum, and if she was honest with herself about it, she got even more aroused if she could wait until the very last minute before going, nearly to the point of having an accident. That was why when she started going in her panties coming back from Lori's graduation, no one except her knew that she was extremely turned on when her poop started tenting out her panties, and when she lost a log on the toilet seat. It was also why she nearly had an orgasm when she finally let it all go. For all those reasons, Nora was intent on not pooping until she absolutely couldn't hold it anymore.
The rest of the afternoon was quiet, with the girls hanging out with Nora, all three quietly suppressing their need to take a giant shit, with none admitting it to anyone else yet. Erica was starting to feel her log poking out from time to time, and she'd have to make a conscious effort to keep it from poking out too far. It was becoming hard work, and she wasn't sure how much longer she could hold it like this. Still, she was intent on not embarrassing herself in front of Lori and her parents.
Lori was feeling progressively fuller as the afternoon progressed, especially as the big breakfast and Thanksgiving meal started working through her bowels. By dinner time, she was feeling a fairly substantial amount of pressure in her bowels, and she knew it wouldn't be long before her log would be poking out of her asshole, and she'd be clenching hard to keep it in. She was still going to hold it for Erica's benefit, though Erica hadn't taken note of Lori's discomfort yet.
Nora, oddly enough, was worst off. Unknown to the others, she actually hadn't pooped in days, and the urge she felt washing the dishes was the accumulation of pressure she'd been feeling the better part of the week. Tomorrow would be five days since she'd last pooped, and she was feeling the need to sit on the toilet quite urgently, but she kept on holding it, as it was arousing her more with every passing hour. There was something so naughty, she thought, about holding a massive shit in her bowels with no one else knowing how desperate she was, or how much it turned her on. If someone were to see her poop, heaven forbid if they were to see her have an accident, she might not be able to conceal her arousal. She just didn't plan on that happening.
