Although, with some creatures they basically *have* to fuck during their estrus/heat/“any-other-term-for-a-creatures-period-of-horniness”, and they stay in that state til they get fucked, and if it has something to do with dragon biology, where they get intense feelings of need, and some of that was transferred to Ocellus (Spike and Smolder left DNA on her, and vaginal fluids, etc), and if she somehow incorporated that into herself- Changeling’s don’t just change their physical body after all- then perhaps that’s why sex solved the problem:
It’s building and building, and now there was a release, which lowered the need/arousal to a point where her body could naturally reboot and fix the issue, thus “curing” her… Because with the majority of creatures, when they’re bred they usually don’t get super aroused (til next season obviously), so, maybe tha-  
WHY AM I ANALYZING AND JUSTIFYING A FUCKING PORN COMIC!?

now kiss

Pharynx is a bit meta here…

sex

I’m still on board for having Spike plowing Smolder some more!

Well, I meant have Ember show up for no reason at all (I mean, Thorax was talking about her earlier on), but that’s also a funny idea.

A little while down the line, the changelings get a new queen in ocellus, one they can be proud of, a good queen that births dragon hybrid lings :P

Sex is the solution, Ask

@Jonny Manz  
you mean have Pharynx turn into Ember?

Breaking the 4th wall is getting a little cliche

Ask about sex. It doesn’t have to lead to sex with them, but clearly something is afoot and it would be a shame to not investigate.

Ask about sex - and then hope something crazy happens, like a threesome between Spike, Thorax, and Ember (hell, maybe throw Pharynx in there and make it a foursome - or drag Ocellus back in and have it be a full-fledged orgy XD)

Ask

@PapaDragon69  
Giggity giggity! :-P

Go on, ask!

@FurryXXI  
We don’t know what was Thorax’s past sex life. For all we know, he could’ve been a changeling Quagmire.

Ask

@FurryXXI  
nah, I’m pretty sure that Thorax and Pharynx had sex before Spike

Don’t ask anything! That’d be a bad idea, just like what Spike did to Ocellus back at school!

Ask

Ask

I say ask

Hey, I’ve been waiting for this moment! ASK ABOUT SEX WITH THORAX PLEASE!
