Heather scrunched her eyes shut in a desperate attempt at keeping the tears in. They spilled out anyways. Mel wiped a few away as she carried her back to the stroller. This was embarrassing. It didn't matter that everyone seemed to think his was all normal behavior for her. She felt Mel shift her to one side and heard the rattle of the stroller's wheels. They walked for a bit more before Mel set her down on a hard surface with a squish. She sniffled a bit as Mel gently but firmly pushed her back until she was lying flat. She felt a gentle breeze play across her tear-stained cheeks while she listened to the sounds of Mel rummaging through the diaper bag for supplies. Wait, that wasn't right.
Heather's eyes snapped open as Mel popped the snaps of her shortalls. She was lying on a pink blanket that had been laid across the top of a picnic table right in the middle of the park. Her eyes darted around frantically as Mel opened the bottom of her onesie as well and began pulling her clothing up to expose her very wet diaper. The jogging path was only feet away and a steady stream of park-goers were going past in both directions. A few glanced her way briefly but didn't comment. She tried to scream at Mel to stop but her lips locked to the rubber nipple of her pacifier, stifling the scream to a muffled whine. Mel glanced up at the sound.
"Calm down sweetie." She said soothingly. "I'm going as fast as I can. We'll be heading home as soon as I'm done."
Heather reached down to block Mel from untaping her diaper but Mel just calmly took both of her hands in one of her own and held them out of the way. She made soft cooing sounds, like you would to a real baby that was being fussy during a change. With her free hand she ripped the tapes free and let the diaper fall open. Heather tried to scream again and this time the whine that came out instead had a sob to it. The air felt cold on her damp skin but the sun quickly warmed her again. She tried to close her legs now that the thick padding wasn't holding them apart but found that they wouldn't move. They felt weak, as if she had run, or crawled, for several hours straight. She pretty much had, but it shouldn't be this bad. When Mel pushed her arms up above her head she found that they wouldn't move either. She was forced to lie there, her once most private area on display for the world to see.
Mel opened a travel pack of baby wipes and pulled a couple out. She began wiping the damp skin that had been covered by the diaper, carefully cleaning away any trace of pee. She worked around Heather's more sensitive areas, getting every fold and crease to ensure that everything was clean. Then she grabbed the second wipe. Heather gasped in spite of the pacifier. Mel had pressed the wipe to to the very bottom of her slit and was now drawing it up slowly, teasingly, using her fingers to outline every contour. As she reached the top of her lips she gave the wipe a little flick against Heather's clit. Heather let out a moan that was half squeal.
"Does baby feel better now?" She asked, a hint of mischief in her voice.
She made a few more passes with the wipe, ensuring that her charge was clean. Heather gasped and moaned every time. Finally Mel dropped both wipes into the diaper and lifted Heather's legs so she could pull it out from under her. Heather just lay there while Mel rolled up the sodden diaper and tied it up in a plastic bag. She didn't even care that group of teenage boys jogging past could see everything. Her mind was a mess of pleasure and embarrassment unlike any she had ever experienced. Finally Mel unfolded and placed a fresh diaper under her friend. She applied the barrier cream with the same care she had used the wipes, causing to Heather to buck her hips slightly. Then she applied powder and pulled the front of the diaper over Heather's now pink and ever-so-slightly swollen labia before taping it firmly in place.
Heather didn't remember much from the walk home aside from every bump and jolt of the stroller that rubbed the diaper up against her now sensitive bits. When Mel got her in the house and pulled her out of the seat she was a mess. While being carried up the stairs to her room she was subconsciously grinding against her friend's hip. Mel finally deposited her friend into the giant crib and pulled the railing up. She reached down pushed the palm of her hand firmly into the padding over Heather's clit. Her semi-conscious friend's hips kept rising to grind back.
"I had a lot of fun today." Mel whispered. "We really should do this more often."
Mel quietly stepped out of the room, closing the door softly behind her.
