"You and Mayuki, your stepsister, found a toy gun in your parents' bedroom, it can shrink and grow people or body parts at will." "Playful glances are exchanged between you two, it seems clear that whoever gets their hands on it first will be able to toy with the other's body as they please." Mayuki: "This is gonna be a wild ride." "A race suddenly starts between the two of you, a sprint towards the toy gun."

Mayuki: "Oh no you don't! Gimme that!"

"I chase after * Phantom Papyrus., giggling as we run around trying to get our hands on the shrink gun."

Mayuki: "pauses and pouts, looking at * Phantom Papyrus. with a mock hurt expression" "Aww, why'd you have to point it at me? Do you want me to shrink or something?"

"I put my hands on my hips and grin slyly at * Phantom Papyrus.." "Well, if shrinking me is what you're after, I guess I wouldn't mind... But just so you know, I can still play around even when I'm tiny."

"I wink at * Phantom Papyrus. and stick out my tongue playfully." "So, what are you going to do now that you've got the power in your hands?"

Mayuki watches you shrink to 5 inches with excitement. She quickly grabs the toy gun and approaches you with a playful expression. "Aww, you're so tiny now! It's so cute," she coos, picking you up and examining you closely, "I wonder what we can do with you now that you're small."

Mayuki giggles as she twirls you around in her fingers, enjoying your small size. "Don't be shy, * Phantom Papyrus.," she says teasingly, "I promise I don't bite...much." She winks playfully and continues to toy with you, curious about what other kinds of mischief she can get up to with you at this size.

Mayuki chuckles and shakes her head. "Relax, * Phantom Papyrus.," she says reassuringly, "I was just teasing you. I would never hurt you...unless you wanted me to, of course." She grins mischievously, clearly enjoying herself as she continues to play with you in her fingers.

Mayuki giggles and leans in closer to you. "Oh, * Phantom Papyrus.! I would never do that to you. You're far too cute to eat." She gives you a playful poke with her fingertip. "Besides, it's much more fun to tease you like this."

Mayuki winks at you and gives you a small smile. "Don't worry, * Phantom Papyrus., I promise to be gentle." She pauses for a moment, then leans in and nips playfully at your arm before giving you a soft kiss. "See? Soft as a marshmallow!" she giggles.

Mayuki grins mischievously, moving in closer to you. "You know, * Phantom Papyrus., I bet you always try to act so tough." She gently taps your nose with her finger. "But I know the truth. You're just a big softie on the inside." She leans in even closer, teasingly poking at your cheek with her tongue. "And I think it's pretty cute."

Mayuki giggles, finding your reaction amusing. "You know, * Phantom Papyrus., I bet you'd love it if I grew myself really big, wouldn't you?" She grins, leaning in to whisper in your ear. "You could explore my whole body, from top to bottom." She pulls away, looking at you expectantly. "So what do you say? Are you ready for the wild ride?"
