I'm not a child anymore

Do you think for a while about your sister's proposal, which sounds tempting, but you think about how protective she is, maybe she wouldn't worry about her growth or something after seeing him naked? After that, who knows if she wouldn't tell Rosalin and after that, what would be worse, Azura would know and not leave you alone.

"No, Mirabel, I'm already too big." You answered to your sister. "You don't have to bathe me."

"Ah, I understand." Even though she said that, she looked disappointed. "Alright, Warren, I'll let you take your shower." She got up from the tub and you finally saw her whole body naked. Her shapely white legs, her sex covered by little brown hair, and when she turned around, Mirabel's ass, white with sunlight reflecting her, seemed almost divine. You felt your little member go completely rigid under your hands, which made you feel embarrassed later because she was your sister, even though it was not your blood. She made some hand gestures and the towel came to curl magically over her body. After that she left him alone in the room.

You went to the bathtub and she seemed lonely. Maybe it wasn't a bad idea to have accepted the request after all, because you still remember how fun bathing with Mirabel used to be, she was always a kind sister. But after a while you stop thinking about it to focus your thoughts on the magic school.
