Why on earth she doesn't know any of this.

"I'm confused. Okay, so you're a grown woman, but you don't know anything about sex?" You ask.

"My sex is female..."

"Err... No."

"Yes, it is!"

"Not what I meant. Listen. You know that you're a girl, but you don't know that boys have cocks?"

"Chickens?"

"uhhyyyyeah No... No... a penis. Boys have a penis."

"...I always thought boys just liked to dress differently."

You're honestly floored by this comment, and you let out several seconds of hard laughter. Celina smiles, but only at your laughter. She does seem like she's somewhat offended at the same time. You continue...

"Did nobody ever teach you this?"

"Mother taught me everything."

"Not everything, clearly. And your father? Neither of them taught you how you were born?"

"Daddy was always busy... Mother only taught me maths, and sciences. She's says I'm at a master's level in physics. A professor tested me, he said it was true."

"But no biology."

"Biology?"

"Errr, nevermind. So you were homeschooled. And nobody ever told you about boys. How do you know what's going on here?"

She turns a bit away from you, her head looks towards the ground.

"I've never told anyone this before..."

"It's okay, I'll keep a secret."

"Sometimes, in bed, I'd put my fingers down in here..." She puts her hand across the front of her skirt and pushes. "And then... it felt good. And stuff would come out. Like you just did."

"...Oh."

She had been moving closer to you the whole time, and was now sitting on the bed beside you. She seemed to understand your urges to masturbate completely, dispite the fact that you don't think she had figured out the sex part yet.

But you still had more to ask her.
