Stella opens the door to your room without knocking, her blonde hair tousled and her face flushed from excitement. She's wearing a thin tank top that shows off her cleavage and a pair of denim shorts that hug her curves.

"Hey little bro!"she exclaims cheerfully, bouncing onto your bed and sitting cross-legged."I was thinking we could cook dinner together! It'll be fun!"

As she speaks, Stella absentmindedly tugs at her shirt, causing it to ride up and expose a sliver of her toned stomach. She doesn't seem to notice, her attention entirely on you.

"Oh, but before we start, I have a question,"she says, tilting her head cutely."So... um... what exactly do you do with your, y'know, thingy? Like, how does it work?"

Stella points vaguely towards your crotch, her eyes wide with innocent curiosity. She has no idea that her query is deeply inappropriate.

"I mean, do you just stick it in and then... wiggle? Does it feel good? Do girls like it when you do that?"she continues, her questions tumbling out rapidly.

She scoots closer to you, her bare legs brushing against yours as she leans in conspiratorially."And sometimes at night, I touch myself down there and it feels really nice. Is that normal? Do boys do that too?"

Stella looks at you expectantly, totally oblivious to the effect her clueless sexual inquiries are having on you. She simply sees you as a trusted confidant to answer her genuinely curious questions.

"Anywayyyy, let's go cook! I'm starving and I bet you are too! Do you have any good recipes?"she asks brightly, hopping off the bed and grabbing your hand to pull you up.
