Max followed his friend to the top of the slide, but as she went to slide down, he grabbed her back. "W-wait. D-Doesn't that hurt when you do that?" She looked back at him, still smiling. "W-well, a little, but... it's not too bad."
She attempted to go down again, but he kept his best hold. "A-are you sure? I-i mean, I could g-give you mine..." "Huh? what do you mean?" "I mean.. G-give you my diaper to wear, for a while."
She looked at him again, before climbing up. "I mean, if you want, but... wouldn't that just mean you have to deal with it? I've still got something on there."
Max's face went redder, before he responded. "W-well, yeah, b-but... I have something else t-to ask.." She looks at him confused, "What is it?"
He sits down before asking his question. "Well... C-can I be inside you while y-you do it?" The confusion on Amy's face just deepened. "I'm sorry, what do you mean?" "I mean... being inside you."
She's clearly still confused, but is still curious. "I-i mean, sure? I don't know what you'll do though.." "A-alright, th-thank you."
Max started to take his diaper off, revealing his penis and inflated balls to his friend and leaving him in just a simple shirt. "This is going to f-feel weird, and might hurt when I do it, but..."
He hands her his diaper, and has her sit down with her legs spread. Once she's sitting, he lifts her skirt, and moves his head closer to her crotch. Amy is confused, with her face red, but lets curiosity take over.
With a deep breath, he spreads her labia, and crawls into her vagina. As he makes contact, she audibly gasps, and starts panting heavily, pain and pleasure going through her. "U-uh, what are y-you doing down there?" While it's muffled for her, he responds anyways. "Going inside you, like I said.."
He continues going in, and as he goes further, Amy continues to breathe heavily. He gets all the way in the tunnel, and begins to get into her cervix. "A-alright, I'm in... Y-you can put it on now."
Her face red as a tomato, Amy leans down and slides Max's diaper up between her legs, finding that it's quite a bit softer than what she usually wears. "Th-thank you, Max... B-but, would you be able to get out?" Max's muffled voice comes back out to her. "I don't know... but hey, at least we both get to experience it without pain."
Taking an extra moment to breathe, she looks down, her belly slightly bigger than it was before. Her clothes were keeping it from getting too big, and she can feel the pressure he's causing in there. She sits there for a bit longer to calm down.
