You decided the best course of action was to wait until nap time when Juliaunna was lying down and not moving so you could just climb out. That only meant you'd have to survive the five or so hours remaining until naptime occurs, which may be harder than anticipated. As Juliaunna walked around the play room deciding what to do next, you took in your surroundings and figured out where the safest place in a girl's pull up was. The motion of JuJu B walking and running was noticeable, but didn't physically impact you much as you crawled to the very back of her pull up. From there you thought that it would be easiest to leave through the legs once she falls asleep, and you would be furthest away from her body, so it would be less likely for her to feel you and get freaked out by something in her pull up. As you nestled into a crevice towards the back of Juliaunna's pull up, you thought how reasonable this seemed. Despite being next to someone's asshole, it smelled pretty normal, it was a fresh pull up after all, and because you had just changed her she probably won't have to go again before naptime. The conditions became slightly worse after an hour.
As you waited for the day to continue from inside the massive pull up, you really started feeling the heat. With how insulated the padding around you was, and how tightly the waistband and leg holes were, the temperature rose around you quicker than a hot car, and unfortunately that meant that the stench was going to get a lot worse. It didn't happen all at once, but over the course of the first hour you began to notice an unpleasant sweat like smell developing in the pull up. It made sense as Juliaunna was walking around from area to area seeing who she wanted to play with, and the constant motion built up some sweat in the hot pull up, but how bad it smelled was surprising to you. You were staring right into where her shit came from, but it wasn't the smell of ass. It smelled weirdly sweet with the chemical smell of the pull up mixing with the natural scent of the sweat. It was about to get a whole lot worse as Juju B started a game of tag with her friends.
You couldn't hear what was going on, but you felt the movement of Juliaunna's legs get a lot more random and strong. You could also hear loud laughter and giggling from multiple girls above you. As Juliaunna continued to run around, darting back and forth away from her friends, the sweaty smell increased tenfold, and you began to regret your decision to stay here until naptime. As Juju B jumped to her side away from someone trying to tag her a tiny fart escaped her. So small and short that she didn't even notice, but the sudden release of gas sounded like a balloon pop from within the cheeks in front of your face. Then the faint smell of shit filled your cramped, sweaty atmosphere. It wasn't too strong, but it just reminded you of the many times you've had to change Juliaunna's pull ups, and you didn't want to be anywhere near here when that time comes. The bigger annoyance was how long the stench of her fart was staying in the air. Since there isn't much airflow in the pull up, the used diaper smell hung in the confined space with you as Juju kept running around, no idea how much discomfort she's putting her old best friend into.
Right as Abby tagged Julianna, she fell backwards causing the crevice you were sitting in to be launched up right next to Juju's asshole. The massive orifice was intimidating to see in such excruciating detail, and the incredibly musky smell flooded your senses. Uninjured, Juju stood right back up and fixed the wedgie that her pullup had created, but did she feel your presence in the brief moment you were next to her skin?
