Yoko the Half-Genie Sylveon belongs to me

“Mmm…this place is beautiful, isn’t it, Anon-kun?”

You couldn’t help but agree. Yoko had been right after all; this beach truly was a divine looking place. The curvy Sylveon had stopped by your apartment for a visit earlier today. While you were tidying the place up a little, she was scrolling through social media. You heard her gasp just before she got your attention, showing you the location of a tropical beach on her phone. Yoko practically begged you to come with her so the two of you could check it out.

“Listen, Anon-kun: today is a Friday. You have the rest of today and all of the weekend off of work. I can use my magic to teleport us right now, and it’ll only be for a few hours. What do you say?”
A few hours… I suppose it couldn’t hurt.
“Alright, if you say so.” You grinned, tousling her brown, shoulder long hair.
The two of you had changed into beach attire–board shorts for yourself and a sky blue genie outfit with gold adornments for the Sylveon—and grabbed a few towels and snacks. Just like that, you held hands with Yoko as she chanted a spell, and the two of you were teleported to a tropical paradise.

Despite your initial concern, now that you were here, you had to admit:
“Okay, you were right. This beach is beautiful… maybe coming here wasn’t such a bad idea after all!”

You did find it a bit odd no one else was out here, but maybe the beach was hard to reach without teleportation magic. Just as you set down the beach towels and snacks, you looked over towards Yoko. She went walking further out on the beach… and then, suddenly…
Schlorp!
…her foot was sucked underground in an instant!

“Oh my…” Yoko gasped, putting a hand over her mouth.
Instantly, you recognized the pillowy crater that had formed around her. It had to be quicksand. “Yoko! Be careful! I don’t have any rope aro—”
“Anon-kun, don’t worry!” She called back, looking over her shoulder at you. “I think I’ll be fine. Just… keep an eye on me, okay?”
Wait… keep an eye on her? What’s she talking about…?
Considering Yoko was a half-genie Sylveon, she could easily conjure up some magic to get herself out. At the very least, she could make a rope appear so you could help pull her out. Still… something didn’t feel right about what she said. Quicksand was dangerous… she shouldn’t be toying around with that hungry suction!

Unless…
…She doesn’t know… does she…?

Yoko slowly turned around to face you, lifting up her sunken leg as the other one started to find itself disappearing into the muck. Once she was looking directly at you, that same, quicksand-soaked leg idly plopped back down. Her arms began to raise in a way that… looked like some sort of exotic dance? You weren’t entirely sure, but as her hips swished back and forth as one knee sank into the earth, then the other… you could only assume the Sylveon’s dancing was meant for an audience to… well, it was pretty obvious, given how suggestive it was.
As her soft, plush thighs were sweetly sucked down by the mud, Yoko used the last of her legs to pump herself deeper and deeper. The earth squelched and bubbled eagerly as she sank down to her hips. She placed her hands on the mud to keep herself in place for a bit.

“Anon-kun... I’m sorry for not telling you earlier, but… I actually visited this beach earlier today. I know about your… well… tastes.” She gave him a small smile.
“Wait, how did you find ou—”
Yoko put a finger to her muzzle, silently shushing you and giving an excited giggle at your reaction. “You ask too many questions, Anon-kun! I know you’ve been pretty stressed lately, and I just want to help make you feel better, y’know? I hope you won’t mind…” She paused, then gave a playful smirk, “...actually, you better not mind!” With a laugh, she gave a sultry look to you. “You may as well let me keep going… I’m in pretty deep already. What do you say? Can you watch me, just this once?”
Your face went warm with embarrassment. Sure, you knew being into stuff like this was weird, and it was even more awkward now that Yoko knew about it… but, then again… she seemed to be pretty accepting of it all. Why not make the best out of it and enjoy the show?
“If you say so, Yoko… then… yeah. I’ll watch.”
“Thank you, Anon-kun~~”

Slowly, steadily, the half-genie puts her hands back up, lifting each side of her hips one after the other as she looks right into your eyes. She winks, holding the expression as her singular eye continues to look sultrily at you.
“Be sure to watch closely, Anon-kun. This is a once-in-a-lifetime opportunity… and if you blink, you just might miss me sink aaaaalll the way…~”
