A Shared Snowflake (RWBYxNeptunia crossover RP) (Private with Moemura)

Purple Heart let out a smile at Weiss's request to wear a swim diaper and told her "That'll be no issue. Lucky for us that Napgear is a very attentive girl, so she already got you some swim diapers when she had gotten the other stuff for your nursery, just in case. Please wait here until I get back." And with that, Neptune left to go back to Weiss's nursery to pick one of her swim diapers up for her and returned within a few minutes.

Once she did and started running the bath for Weiss, Purple Heart then sat down onto the toilet lid and told the heiress "Come over here so I can get you changed into your bathwear." When Weiss did, Neptune started by pulling down her still clean diaper and remarked "...I think I'll save this one to put you back into once we get done with your bath. Can't let a good diaper go to waste after all." as she put the diaper aside. She then held the fresh swim diaper out but low so that Weiss could step into it as she explained to her "Now...step into these and I'll pull them up onto you for you."

"Swim diapers?" Weiss muttered. Before she could question further Purple Heart was already out of the bathroom. The heiress figured that swimming while padded was gonna be on the woman's agenda. Weiss didn't have long to ponder on that as Purple Heart returned almost as quickly as she had left.

Knowing the drill the girl waddled towards the woman, flustering cutely as her diaper was slid off with no intent on Purple Heart's part to dispose of it completely. After all, it had still yet to be used. "F...fine with me," she replied as she looked down towards the floor, seeing the swim diaper ready to be put on. Without question Weiss stepped onto the holes of the diaper, remaining still as she patiently waited for the garment to be slid right up.

And slide up up onto Weiss Neptune did, pulling it up all the way up to her hips where it snuggly and comfortably fit on her. Looking down at it, the heiress would find that the swim diaper itself was largely a solid green-ish blue color, though the bubble prints covering mainly the bottom-half of it were more of a lighter yet still normal-hued blue in color to make them be visually present. And wearing it, she could note how it had somewhat less of a fluffy feel to it compared to the diapers she normally wears. There was still padding to it of course, but it felt like the padding itself was treated a bit differently to allow it to not soak in any water at all. Fine for holding bowel accidents at least, even if bladder ones seemed like they wouldn't be able to be held inside the diaper at all.

Purple Heart just smiled a little at the sight as she told Weiss "I'll let you get used to that for a bit, while get your bath ready." as she got up and headed back over to the bathub. After letting the water flow for about a minute longer, Neptune stopped the water and made sure it was perfectly warm without being too hot for Weiss to get into. "...Okay Weiss, you can get in now. I think the water's just fine now." She then replied to the white-haired girl once she had gotten it to a point that she expected that the heiress would enjoy soaking herself in.
