Kronii aging herself backwards into a childlike form
Hates that a time anomaly forced her to do this
Hates that she can't reach things on high shelves anymore
Hates that she has to ask for help to even reach something on the counter properly
Most of all, she hates that she can't sleep with (You).
Until she actually tries.
"Ugh." She clicks her tongue, feeling your erection press up against her childlike belly. "Seriously?"
You can't really control your body, you explain. You try to make it sound like a compliment, that you love her so much even in a kid's body.
"Tch. No, I know what it is," she tells you, sitting up. "You're just a pervert."
Blink, try to refute her words.
"Shut up." She feels your cock through your pajamas, glaring up at you—lacking the refinement of her adult self, she just looks adorable. "You're a huge pervert who gets off to children."
What? You're not a pedo!
"Pff, maybe you say that. But this part of your body is more honest," she tells you.
Her hands are so small it takes both of her hands to wrap around your dick properly.
The soft hands on your member make you groan, biting your tongue to hide anything else.
"C'mon, admit it. Tell me you're a creep who gets off to little girls, and I'll let you cum." She's grinning now, clearly enjoying having found such a weak point.
Refuse—even through the sensation of her body brushing up against you. Was she using her powers on you again?
"Say it!" she insists, pumping your cock faster and faster, until you were aching to burst.
"I-I'm a creep who gets off to little girls," you choke out.
"Good boy," she tells you, and releases her mental grip on you, allowing you to cum. "Or should I say… good job, onii-chan!" She lays a kiss on the tip of your dick, and you burst, cumming like a fire hose. Christ, you'd never cum that hard before, not even when Kronii forced you to edge for eight entire hourse.
"Hm." Kronii licks her finger, cleaning it of your semen. "Maybe being like this isn't so bad after all."

I'm not even a lolicon, I swear. I just had the idea.
