Mirabel

Just sticking her head out, Mirabel emerges from the waters, giving to you a gentle smile. You, red with shame, immediately cover your male parts, even if Mirabel wasn't seeing, because you and your back were to her.

"I didn't know you were here." You answer embarrassed.

"It's fine, we are siblings." She then begins to rise higher from the waters, this time revealing her naked front, the nipples of her large breasts were covered by her wavy wet hair. You had seen her naked before, as a child, but this time it was ... different. "Why are you embarrassed?"

"Is nothing!" You respond by avoiding her looking straight.

"Hey, little brother, do you remember that I used to bathe you here, at this fountain, when you were younger?"

"What's the matter?" You ask suspiciously.

"Ah, it's just that you're growing up so fast! Today you will start studying at Crimson Grimoire and in a moment you will be with your family!"

"Don't rush things!"

"But it's true!" She pouted. "Today you have come naked here, this cannot be a coincidence."

"What you mean?"

"Ah, that may be my last chance to bathe you again."

"What ?! That won't happen!"

"Oh, little brother, one last time, come on! Please, for the old times."

"I'm not a child anymore, Mirabel, I can bathe myself."

"But it is not the same." She pouted again. "I don't know what you're ashamed of, I've seen your little wee wee many times."

You blushed to hear her address your cock like that.

"D... don't call it that!"

"Ah, that's true, right?" She stuck her tongue out, mischievous. "He must be grown up already, and that's why! You, after today, will be too grown up for your big sister. So, little brother, do it for me, please, one last time." She gave you a big-eyed, hard look that was very hard to resist... even more so after you looked down a little and came across her big breasts. You felt your penis start to come to life.
