Blue Lets Her Have Naughty Fun

She found out a moment later, when Blue Diamond abruptly said, "Of course, you may be my baby, but I realize you still have the same urges as the human adult. As such, I would be happy to indulge you in that fashion, too."

"What do you mean... Mommy?" Priyanka asked, genuinely curious.

Blue Diamond smiled at being addressed as such, and she said, "Rather than explain, let me show you."

She then held Priyanka securely in her left hand, before holding up her right hand and extending her index finger. She brought that one enormous finger down to the front of Priyanka's drenched diaper and began... rubbing.

Priyanka bit her lip to keep from yelping in shock. Then she did so to prevent herself from moaning in arousal.

"Do you like that, baby girl?" Blue Diamond asked, more motherly than sensually.

Priyanka was speechless, but she found the strength to nod in affirmative. It had been a while since she and Doug had last made love, so she had had plenty of pent up energy left over in that regard. As Blue increased the speed and intensity of her rubbing, Priyanka felt herself beginning to hump her padded crotch in rhythm to it. Before very long, she was also moaning excitedly. "That... that feels so good!" she exclaimed.

"Mommy's so glad to hear that," said Blue, keeping up the rubbing on the much smaller human. "It seems you're about to have a very wet diaper for TWO reasons."

Embarrassing as the whole spectacle was, Priyanka was hardly in a position to voice any form of disagreement. Only a few moments later, she arched her back and squealed in pure ecstasy, cumming into the front of her already wet diaper.
