You are Seth, and you just arrived at Ashley's house for the sleepover. The other kids are already there, Joey and Katie. Katie opened the door and let you in.
"Come on in, Seth! Party's just getting started." Katie said.
She was wearing a cute nightie. Joey had on regular pajamas. You hadn't changed into your pajamas yet but you had them in your bag for when it was time to change.
"So, where's Ashley?" You asked.
Katie smiled.
"Actually, she's upstairs. She wanted to ask you something!" Katie said, excitedly.
you grinned wide, hoping this meant she liked you. Quickly you ran upstairs near her room. Katie followed close behind.
As you walked upstairs, you heard Ashley's voice.
"Seth, is that you?" She said.
"Sure is!" you replied.
"Hey... Seth... Come here... I want you to do something for me." She said.
You opened the door to Ashley's room and saw the young girl sitting near her desk. She was wearing a thick white diaper and a bra, although her chest was flat so she didn't really need one. You'd never seen her in this state of undress before and it got you a bit more excited. Your heart was racing now.
"So, Seth, you know how I need diapers, right?" She said.
You nodded.
"Well... um... I'm kind of... self-conscious about them. It would really mean a lot if you wore diapers tonight too." Ashley said.
This wasn't what you had hoped she would say, but you felt you could work with this. Katie and Ashley looked at you expectantly. You thought this over for a moment. You had a major crush on both the girls here, Ashley and Katie, and you figured wearing a diaper around them to be nice would score a lot of points with them, even if it was kind of humiliating and uncomfortable. you also figured Katie was used to seeing Ashley in diapers and she wouldn't think less of you for wearing them too... you hoped.
"Um... All right. I can do that." You said.
Ashley smiled and nodded.
"You have no idea how much this means to me, Seth." She said.
Katie walked over to the changing station on Ashley's floor.
"Come on, boy. Strip naked so we can diaper you." She said.
You began taking off all your clothes but stifled for a moment at your underwear. These girls had never seen your tiny penis before.
"You're not having second thoughts, are you?" Katie said.
She was already reaching into a diaper drawer to take one out.
"No... it's just... I've never been naked around girls before." You said.
Ashley giggled.
"Oh, tell you what, Seth, I'll let you watch me get changed if you do this for me." Ashley said.
She patted the front of her diaper for emphasis. The thought of seeing Ashley naked was enough to embolden you. You removed your last bit of clothing and laid down naked on the changing station. Ashley and Katie looked at your tiny penis for a moment.
"Aw, it's kind of cute." Katie said.
You k new it was cute, and were proud of that. Katie then powdered you up and taped the thick white diaper around your waist. She even checked the legs to make sure it wouldn't leak.
"Now, Seth, you don't have to say yes, but since you're diapered too..." Ashley said.
"Okay, what is it?" You asked, sitting up.
"Do you think if you have to go you could use the diaper too?" Ashley asked.
This was a lot to ask for, but you felt like you had a shot at being Ashley's boyfriend if you said yes.
"Ah, I can try." You said.
Ashley leaned in and gave you a hug, a tight one around your shoulders. She was practice ally crying tears of joy now.
"Thank you, Seth." She said.
So, here you were at the sleepover party, wearing nothing but a diaper for Ashley. What do you do now?
