Bathtime for your Puppet Puny Pervert chapter 8 by dellobenedetto

Much though you wanted to just parade Nikki through town, you felt following a bit of what she said would help keep her from getting suspicious, and she did say she wanted to wash up. And from being up close to her, you could tell she needed one. So you carefully walked her up to the bathroom, having her turn on the water. As you waited for the tub to fill, you spent some time making her grope at her boobs. "Ah, I'm so proud of these," she says absentmindedly as she rubs her nipples, "Definitely gonna show them off at a party tonight."

Ooh, she had plans to go to a party? That'll be fun to puppet her around in, maybe making her do something she's never done before—like maybe make her get into a threesome, or put her into an eating contest! The ideas were limitless, though also unclear until you know what this potential party will be like. For now, you got Nikki into the water now that it was filled, grabbing the body lotion and making sure she washed every part of her body—her nipples and pussy especially. "Ah, nothing like a good soak to loosen up," she commented as you coated her body in soap that was summarily washed off.

Eventually, the bath finished, and you pulled Nikki's body out and drained the water—and you couldn't help but hump the gray matter a bit as you admired her ample naked figure, making her bounce on her heels as a result. "Ooh! Maybe I should go for a run, I feel so full of energy after all that."
A run? That sounds good. All you need to do is figure out an outfit for your sister to wear... Or perhaps, you could just have her head out in naught but her birthday suit... What'll it be?
