A Fine Young Woman

"Uh, nothing. Just thinking about how much you've grown since I left. Last time I saw you, you were little more than an ankle biter. You've grown into a, ugh, fine young woman."
>You cringe internally at that.
>She's grown alright.
>In more ways than one.
>You're sitting on a bench next to a lake right outside of town.
>You got here just a few days ago and have been going around checking up on old friends.
>Some of them haven't changed at all.
>Some of them are like completely different people.
>Sweetie Belle, the younger sister of your close friend Rarity, is one of the latter.
>When you last saw her, she was still in middle school.
>Now...
>She giggles a little.
>"Well, thanks Anon. And you've grown into a finer young man."
>You give a small smile.
>"Anyways, I think we've been sitting for long enough, I want to get wet."
>Some rather naughty thoughts entered your mind unbidden at that.
>Dear god, pls help
"Alright, alright. Let's go."
>She pulls you up and attempts to tug you towards the water's edge.
>As you stand there, looking at the semi-murky liquid sloshing at the shore, Sweetie suddenly dashes forward.
>Her as she gets ankle deep in the water, she turns around begins to splash you with it.
>"What are you waiting for Nonny? Take your shirt off and get in here!"
>You quickly whip off your t-shirt and throw it aside.
>Sweetie, however, doesn't let up.
>By the time your feet actually touch the water, you're already soaking wet.
>You charge in, past Sweetie, and turn around.
"You think you're funny, dontcha?"
>Her smile falters as yours grows wider.
"Let's see how you like it."
>You take a step towards her.
>"Haha, ok Anon, you've made your point, I don't-
>She starts to backpedal.
>Too late.
>She squeals as you lunge forward and grab her.
>"Non, d-don't!"
>You carry her until you're in waist deep.
>You launch her towards the deeper water, which she hits with a satisfying splash.
>Her head emerges a moment later.
>She doesn't look too happy.
>However, the glum look on her pretty, youthful face, combined with her long hair clumping together in comical shapes, only makes you want to laugh.
>And you do.
>"What? What's so funny?!"
>You pause for a second, only to burst into even louder laughter.
>She pouts at you for a second, before she finally sees her reflection in the water.
>She begins to chuckle.
>Soon the two of you are are practically in hysterics, bent over in laughter.
>You're the first to come back down.
>Maybe she hasn't changed as much as you thought.
>You spend a bit more time splashing each other before the two of decide you've had enough.
>As she exits the water, you lag behind her.
>You can't help but stare at her beautiful young body, wet and glistening in the afternoon sun.
>Goddamn, you need to snap out of this.
>She's your friend's kid sister, for God's sake!
>And yet, a part of you doesn't care.
>It doesn't care that you knew her since she was a little kid.
>It doesn't care that you're 23 while she's barely 18.
>Somewhere along the way, you realize that you are now driving back to Rarity's house.
>"Hey Anon?"
>You give Sweetie Belle a quick glance.
"Yeah?"
>"I've been wondering..."
"Yeah?"
>"Well..."
"...Yeah?"
>"Do you have a girlfriend?"
>...
>Oh brother.
"No, no I don't. Why do you ask?"
>She shrugs and looks away nonchalantly.
>"Oh, no reason."
>She couldn't mean what you think she means?
>She looks out the window for moment, watching the scenery pass by.
>"You know, my 18th birthday is in a week. I was wondering if you wanted to come."
"Of course I'll come Sweetie. I wouldn't miss it for the world."
>As you say this, you quickly reach over and tussle her still damp hair.
>She giggles and playfully shoves your arm away.
"S-stop! You'll ruin my hair!"
>You chuckle.
>You need to stop thinking like that.
>Get your mind out of the gutter, Anon.
>Her body may be that of a woman, but she's still the fun loving kid you knew, right?
>You pull into Rarity's driveway and get out.
>Sweetie Belle does so as well.
>You are about to start walking up the stairs to their porch when you hear running behind you.
>"Hey Anon, think fast!"
"Whu-"
>Sweetie hug tackles you.
>Thankfully, she doesn't weigh much, and you're a big guy.
>For her, anyways.
>"Thanks again for taking me to the lake, Anon! You know how busy Rarity is nowadays, and since my friends couldn't come and all."
"Again, it was no problem Sweetie. It's not like I didn't have pleasant company.
>She pulls away and looks deeply into your eyes, a slight flush to her cheeks.
>Or maybe this is just your imagination, and that's just a bit of sunburn.
>"Anon, Sweetie? What ARE you two just doing just standing out there?"
"Oh, heh, sorry Rares, Sweetie here was just thanking me for taking her to the lake. Yup, just that, nothing strange going on here!"
>Rarity, standing at the threshold of the doorway, raises an eyebrow at you.
>"...Okay. Well get in here, you two. You're still a bit wet and I don't want you getting pneumonia or something!"
>"Alright Rarity!"
>Sweetie bounds past you into the house.
>You follow in after Rarity.
>"I have your clothes all washed and ironed, darling. I thought it'd be nice to go out later and get something to eat with the girls.
"Thanks Rares. What who's all going?"
>"Twilight, Sunset, Rainbow, Applejack, and Sweetie Belle's friends, Scootaloo and Applebloom."
"What about Pinkie?"
>"She couldn't make it. Family matters."
"Ah. Well, we'll make do."
>You head up to the guest room Rarity so graciously offered you and change.
>She so sweet, that Rarity.
>What would you do without her?
