That Time I Was Reincarnated as a Babysitter (Private with Kakarot)

[Arkin]

Shion happily hugs Rimuru against her chest, loving the sensation of his gooey form pressed against herself. She nods at his suggestion and leaves the room, trying to move quickly to avoid being seen. "Getting to nap with Great Rimuru... I'm so excited!" The quickened pace at which she's walking makes her thick padding crinkle noisily. She usually looks like a very mature and attractive business woman, so the juxtaposition of such a babyish garment around her waist makes her seem absolutely adorable.

Once in the room Rimuru stayed in his slime form but held up a section of his body and a soft purple night shirt appeared in what would look like a 'hand'. "Here, this will be more comfortable for you to sleep in than your suit" he explains.

"You move quite adorably in your diaper Shion. We might have to do this in private more often" he coos.

[Arkin]

Shion looks at the night shirt with a small smile. Any gift from Rimuru is precious, after all. "I-I'm going to change into this... look away if you want to." What she really wants to say is, 'please admire my body,' but she's not shameless enough for that.

As she strips down to just her crinkly diaper and then puts the shirt on, she does a little twirl to show off for him. "W-we can do this whenever you like!"

[kakarot]

Rimuru blushed lightly but did not look until she twirled about. "Good now let's rest" he says.

Once Shion laid with him and they took a nap, he found himself awake first and he returned to his human form and held her head to his chest and gently pet he head.

[Arkin]

"Mhm," Shion nods, getting comfy and falling fast asleep.

The large lady manages to stay asleep for a while, even after Rimuru wakes up she's still snoozing soundly. As he pats her head, she nuzzles his hand and smiles, obviously having some pleasant dreams. Also, the front of her diaper is just a little bit yellow, and the padding is slightly soggy from a small accident.
