Yeah. XD

@Bahamut
 
There’s a reason her wings are puffed out like that

“ Cadance! Spikes in the hot springs with Rarity and Applejack! Can you kick him out? ” twilight exclaimed.
 
“ Ohh~ Spikey-Wikey is here~ ” Cooed the Princess of Love
 
“……” Twilight stared in bewilderment, wondering why Cadance was Blushing at her Cousin Psike

@Animegx43  
It looks like Spike is an adult in this picture and is trying to hide (with Rarity’s help. Twililight just noticed him there.
 
@unicornlord  
I somehow did not put that together.

Oh, and I just noticed that Twilight is pointing at him, possibly to ask Cadence on why Spike is in the women’s bath.  
And Cadence is OK with it.

@Animegx43  
On the other hand, though…You can’t see his body and his head is pretty big for a kid, in proportion to those around him…

@Animegx43  
_{^{… Damn it.}}

@HJSDGCE  
I believe it’s because young children are usually allowed to go in when with their guardian/watcher. Do remember that Spike is only a kid.
 
In other words, he’s a lucky bastard.

What does the apple symbol mean?

@HJSDGCE  
because.  

Why is Spike in the women’s bath?
 
Also, this isn’t a mixed bath since we can see Pinkie peeking at the men’s bath.

@Princess♥Luna  
I think that’s a dock?

@Wolfjira  
Cadance: That just makes it Extra-Naughty Fun~♥

@Background Pony #E951  
Twilight: B-But he’s like a brother.

@Princess♥Luna  
I think its because this is the Safe For Work Edit, and the bottoms of AJ’s swimsuit wasn’t quite put on properly. So you’re actually seeing part of the original image.

You lucky little shit. XD

@unicornlord
 
It’s not that, its the space in-between where the tail is arching over her rear. Could be also how the cheeks on the rear are spread out, it looks rather odd.

@Swashbucklist  
oh my goodness, that got me laughing so hard i woke up the whole house

why we need to add likes and dislikes for the comments section for reasons like this :D  
@Swashbucklist

@Princess♥Luna  
no because he tail is in front of her butt?

@Swashbucklist  
Ok, you definetly win.

Does anybody not see that Applejack has a section of her ass missing just underneath the tail? It looks weird and it’s not lining up where her back is leading downwards.

@Wolfjira  
Cadance: Come on, Twilight, I’m sure we can all have some fun together

@Bahamut  
Cadance [leans over Spike, settles boobs atop his head]: Are these girls giving you a hard time, Mister Brave’n Glorious?
 
Applejack: Somethin’s hard, alright.
 
Rarity: Oh, stop it, you two. If we get him any more flustered we’ll make his head explode.
 
Cadance: What kind of head, and what kind of explosion?
 
[Spike’s face reddens, everyone giggles.]
