"M-Maxwell! What are doing?!" she asked, incredibly nervous.
"I... I thought this was your sister's room. You mentioned a sister the other day at the store... but the diapers threw me off..." Anna looked down at her waist and frowned. "I guess you're incontinent or..."
"No, I..." Anna began. She didn't want to admit it, but seeing as there weren't any other options, she had to. "I... I'm not. I just like diapers..." She buried her face in her hands and cried.
"So where's your sister?" Maxwell asked.
"I don't have one..." Anna admitted. "This is just my room... and my lifestyle..."
Maxwell glanced around the room again. The teen-sized diapers, the giant crib, the stuffed animals... all of it clicked together now. "Sorry for getting into your room... I really didn't think it was yours. You must think I'm just a perverted dweeb..."
Anna was shocked. "N-No... I... I just didn't want you to find out. I didn't think you'd accept me like this... but now you know... You don't even want to be together anymore... " she cried.
Maxwell got up and put his hands on Anna's shoulders. "Anna, relax. This is all fine."
"H-Huh?" Anna asked, choking back tears.
"I respect your passion. Everyone has their own bizarre interests," Maxwell explained. "Even me. I don't go for the popular girls like every other teen at the high school... I just care about the odd ones that everyone else ignores... gals like you, Anna."
Anna blushed and asked, "So you don't hate me...?"
"Hate you? Why'd I ever do that?" Maxwell said, smiling.
Anna smiled back. "So you really do care..."
"Yep," Maxwell said. "Umm... You've still kinda got a, uh... little problem..."
"Hmm?" Anna asked. Maxwell pointed below. She saw that she was still standing there, not just in a diaper, but a WET diaper. She blushed and covered it up. "Ah...! D-Don't look!"
Maxwell just laughed and said, "It's fine, you don't need to be afraid and protective around me. I can actually change you... I mean, if you want."
Anna gasped. "Oh... Oh no, no, no... I can't... I just can't..."
Maxwell calmed her down. "It's fine, just relax. Sure, I've never changed a teen diaper before, but how hard could it be? I change my baby brother all the time." Anna looked at him and smiled. "Cool," Maxwell said, getting up close to Anna and slowly rolling up her shirt.
"Wha... What are you--"
"Shh... I do this with my bro all the time," he said. He began to lightly tickle Anna's belly, which made her giggle a tiny bit. "You like this?"
"Uh... I..." she muttered in between nervous chuckles.
"How about this?" he asked, wrapping around to her side. He tickled her faster, which only made her laugh even harder. "You sure you don't like this?"
Anna tried her hardest to get her words out through her laughing. "No... I... ha-ha... Stop! I'm very... ticklish... there! Ha-ha-ha!"
It wasn't long before Maxwell heard a familiar hissing sound and stopped tickling her. Tears flew out of Anna's eyes as she calmed down from her laughing fit. "Why... heh... Why did you do that?" she asked him.
"I always tickle my brother to make sure everything's out before changing him. Looks like you still had a little bit left," he said. Anna just chuckled slightly. "You feel good and empty now?" he then asked.
"Uh..." Anna muttered, feeling the urge to poop. "No..."
"How come?" Maxwell asked.
"Uhhh..." Anna squeaked. She didn't want to have to tell him. Thankfully, her butt did all the talking as she let a wet fart escape. "T-That..."
"Ah," Maxwell said, completely understanding now. "Well... just drop your dookie." Anna looked down at the ground in shame. "Come on, just do it. It's fine."
She just blushed. "I... I can't..."
Maxwell said, "Just close your eyes and turn around. Just pretend like I'm not here."
"O... Okay..." Anna muttered. She closed her eyes and turned around to face away from Maxwell. She then squatted slightly and began to push. "Hmmmph..." she grunted with a fart.
Maxwell awkwardly watched as Anna messed herself, right there in front of him. He watched the rear of her diaper bulge out, turn brown, and sag down low.
Anna stood there messing her diaper for a little under a minute. When she was done, she slowly got back up. "Hah... aaaah..." she moaned in relief. She turned back around.
Maxwell, now catching onto Anna's baby fascination, smiled and asked, "Baby make a stinky?"
"S-Stop..." Anna giggled, feeling the huge lump in the back of her diaper.
"But seriously though," Maxwell said. "You really stink. Let's get you changed."
Anna led him to the changing table in the back before hopping onto it. "Alright," she sighed. "Let's do this." Maxwell just hesitated. "What's wrong?" Anna asked him.
"I... I'm a bit nervous. I've never... y'know... changed a teenager's diaper before," he explained.
"It's alright," Anna reassured him. "It's not that hard. Besides, in your own words, how hard could it be?"
Maxwell gulped. She did have him there. "If you say so..." He slowly undid the sides of Anna's diaper and peeled it open, exposing her smelly mess. "Ugh...! Never had to deal with this big of a mess before..."
Nervously and quickly, Maxwell disposed of Anna's dirty diaper, wiped her bottom clean, and slid a clean diaper underneath. He finished by taping the sides. "Phew..." he sighed. "Finished."
"Thanks," Anna said. "I've never really had anyone else change me... not even my own mom."
"Really?" Maxwell asked.
"Yeah, I just change myself most of the time, but..." Anna giggled. "...you did a really good job," she said, smiling and getting up from the changing table.
"So... uh... I guess both of us had some awkwardness," Maxwell said. "Y'know... with your diaper obsession. You didn't want to mess in front of me... and I wasn't prepared to change it."
"I guess," Anna said. "We're both pretty awkward." As the two of them walked out of her room, she looked directly at Maxwell. "Y'know... you'd make a really good daddy."
"Well, I obviously haven't really thought about who I'd start a family with just yet--" Maxwell began.
"No, no..." Anna said. She blushed a bit. "I mean... you seem like a great daddy... for me."
"Hmm," Maxwell mumbled. He knew she had this teen baby fantasy and he did think she was cute, but he wanted to know why she thought this. "Why do you say that?"
Anna sighed and sat down on the floor. Maxwell sat beside her, and she began her story. "Well, I barely had a father figure throughout my life. In fact, I almost never had a father figure throughout my life... My own dad... he died just a year or two after I was born..."
Maxwell just stared with his jaw wide open. He couldn't believe what he was hearing.
Anna continued, "It's pretty much just been my mom and I for most of my life. One day, I just kinda discovered this teen baby lifestyle and adapted it. I told my mom, and she seemed to completely understand. She even buys my diapers for me..."
Maxwell couldn't believe that this was actually starting to get to him. Anna, this cute girl with a diaper fetish, had managed to crack his cold shell open and get to his soft heart. He even started to cry a little. "That's... terrible... I'm sorry, Anna."
"Don't be, I've been fine," she said. "I just haven't met anyone like you. I just don't seem to make many close friends because of my secret."
Maxwell put his hand on her shoulder. "Don't worry, Anna. Your secret's safe with me." He winked at her. She blushed back. "If a little daddy-daughter relationship is what you want, I'll gladly oblige."
Anna looked up and asked, "Do you really mean it?"
Maxwell nodded. Then, he did something Anna never expected from a guy: he kissed her. He came in and locked lips with her, showing how much he cared. Anna awkwardly but happily returned the favor. The two of them just sat there kissing for some time, enjoying the other's company.
Eventually, the newly-acquainted couple heard a voice at the bottom of the stairs. "Anna? Anna, are you up here? Are you ho-- Oh!" The two looked down and saw Anna's mom, surprised at what she had just witnessed.
Anna gasped. "Mom! Uh..." she began.
Roslyn just laughed. "Don't worry, I know what I saw." She came up the steps. "So you must be Maxwell," she said, looking right at him.
"Yes, ma'am, and I--" he began.
Roslyn interrupted with, "Oh, please. None of that 'ma'am' trash. Just call me 'Roslyn'. Or 'Mom'. Either works," she said, winking at him. Maxwell just chuckled a bit.
She turned back over to Anna. "So what happened to, uh... hiding your secret?"
"Long story," Anna explained. "But Maxwell actually changed me."
"Oh did he?" Roslyn asked, fascinated. "Thank you, Maxwell."
"No problem, Miss Roslyn," he said.
Roslyn began walking back downstairs, smiled, and said, "Well, I'll be down here if you need anything. Just keep doing... what you two were doing..."
Anna just smiled at Maxwell. He smiled back. "Thanks again," she whispered.
"Anytime, Anna," he said.
"Hey!" Roslyn called from downstairs. "You know there are still nachos down here?"
"Oh, shoot, that's right!" Anna said. She called down to her mom, "Yeah, I just forgot! Sorry!"
"It's fine!" her mom called back. "But I might eat them all if you don't get your diapered butt down here!"
Anna looked at Maxwell. He said, "Nachos sound pretty good right now." Anna smiled at him, and, hand-in-hand, the two walked back downstairs together.
