Leah could hardly hold her excitement as Tina returned to the coach, trying her best to keep her calm facade; she's lucky that whatever the diaper did to her, it also made it feel nice to sit in her mess. Almost immediately, Tina's nose scrunches, and Leah did everything in her power to not smile or let her intentions on. The older woman turned her gaze around the room briefly before it settled on Leah and froze. Leah matched her gaze with innocent curiosity.
"Something wrong, Tina?"
"Do you smell that?"
"Smell what?" Leah asked, and didn't have to fake it; for her, she really did have to focus to notice the smell. Tina sniffs again, looking at Leah with a slight level of suspicion, but didn't drop her disbelief that Leah was the source.
"Did you...fart?" Tina asked with at least a modicum of tact. Leah felt herself blush at the accusation, despite knowing her crime was much more severe.
"Um, gross? No, why-" To Leah's surprise, a sudden cramp sent an audible toot through her ass. She blushed further, the suddenness not just embarrassing her; the thought that she's lacking so much control while wearing diapers that she can't even hold in a fart rang excitement through her. Tina's eyes widen at such a well timed toot only intensified what must've been a rather intense stench.
"O-oops, that slipped right out of me." Leah laughed nervously. Tina's suspicions intensified, narrowing her eyes as they trained on Leah's bottom.
"Show me your diaper."
"What? Why would you-"
"Show me your diaper, Leah!" The woman said sternly. Leah faked a confused look, gulping as her heart beat increased; despite her interest, this was still entirely new to her, and the thought of her stepmom catching her with a dirty diaper gave her equal parts excitement and anxiety. She stood and turned around, allowing herself to smile when she hear Tina gasp incredulously.
"Leah...! You pooped!"
"I what?" Leah tried to keep her voice controlled as she lifted the back of her skirt and looked down at the truly impressive load she created.
"You couldn't tell?"
"Wha- no!" Her face was burning as she jerked around (though it wasn't for the reasons Tina thought it was).
Tina looked at her with wide, confused eyes.
"All that stuff you were saying before about...about *liking* diapers. You-"
"I said what I said, Tina, and I don't need your judgment! I like diapers, but I wasn't trying to use them!" Leah shot back. If she was being honest, the anger was real; of all the times for Tina to be weird about babying her, it happens when she WANTS to be in diapers. Tina's face falls for a fraction of a second before her eyes widen in surprise. It takes Leah a moment to realize why when she feels her diaper getting warmer. Looking down at her still raised skirt, she sees her already soaked diaper starting to leak.
"Leah, your...Leah, why didn't you- you're leaking! Move, move, to the bathroom!" Tina got up and ushered Leah so fast she almost fall over, somewhat mortified by her diaper leaking. It seems the longer she wears them, the worse her control, which both terrified and enamored her. Making it into the bathroom, Tina took inititive as she simutaneously removed her diaper adn pushed her onto the toilet. The heavy mass thumped onto the floor, all while Leah finished peeing in the 'proper place'. Tina looked both angry and baffled. Leah, for her part, felt embarrassed; sure, she wanted to use her diaper, but not to the extend to make such a mess.
"S-sorry about-"
"Goodness gracious, Leah! You...go get a shower, I'll need to clean the floor." And with that, Tina rolled the used diaper and shut the door.
Leah wasted no time in getting a shower, glad to clean off her extra messy behind. By the time she finished drying off, she heard a knock on the door.
"Leah? You finished?"
"Yeah, just drying off!"
"Good. We clearly need to have a discussion."
Leah felt her cheeks burn further, the mix of positive and negative emotions being almost indistinguishable in her head. Wrapping the towel around her, she opens the door to find Tina...
