"Let's get Tina in on this," Tonya says, filling Leah with dread. Tonya pats Leah's head at the look on her friend's face. "I know, I know. But I can't stick by your side forever!"
"Yeah," Leah mumbles. She cringes. "Uh, could you please take charge with explaining everything to Tina? I don't want to do it. Also, Tina thinks I'm a troublemaker, but she trusts you. She wouldn't think you'd go along with this if it was a prank." Tonya nods. Tina has made it no secret that she thinks Tonya is more responsible and reliable than Leah. It's likely to do with how good of a babysitter Tonya is; Tina holds childcarers in high regard.
Tonya sets Leah down and takes her hand. Then she leads her small friend out of the bathroom and to the aisle where Leah last saw Tina. Thankfully, Tina is still there, waiting for her to return. She does a double-take when she sees Tonya and Leah. She puts her hands on her hips.
"All right. What's going on here?"
Like Leah requested, Tonya takes charge, explaining everything to Tina. In the process of telling everything, Leah finds herself triggered a few more times, performing babylike behaviors that back up what Tonya is saying. However, Tina only seems truly convinced when she decides to trigger a command, and tells Leah to poop herself. Leah obediently bends into a squat and begins to grunt. Her face turns red from embarrassment and effort as Tina remains silent, not using the reverse trigger. Tina even stops Tonya from saying it, saying that she'll only believe this whole thing isn't one big prank if Leah fills up her training pants. Which she does.
After spending minutes emptying her bowels in the aisle, Leah straightens. Her training pants have been stretched to their breaking point and are sagging heavily under her. She swallows nervously and looks at Tina.
"All right," Tina says finally. "I believe you." Leah sighs in relief.
"Finally!" Leah squirms slightly, uncomfortable with the mess in her pants. "Um, can- can I get a change?"
