Enough is - Enough––!  
She did achieve one goal, but Chrysalis wasn’t very satisfied.  
Kh.. next time, I’ll make you cry…  
Huh?  
/산기가..?/ (meaning she’s going to have child, i dunno the direct word in english)  
After this, a changeling with white skin was born. Hyangg

It actually looks like a Japanese comic translated into Korean, so the origin is Japanese.

@Perteks  
I think this is actually written in Korean.

@Tornero  
We have a word for that in English.  
We call it “being a cuckold”.  
It’s not that rare in yurop

@Tornero  
Japans are strange, in wrong way :P

@Perteks  
Trust me. I loathe it a lot for good reason.

@Tornero  
I don’t even…

@Perteks  
Yeah, it’s “netorare” or NTR for short.  
It’s a fetish of being aroused by your significant other (mostly married) cheating on you.

@Tornero  
NTR fetish ?

Well, Chrysalis wanted to break apart Cadance and Shining, she needed to get some sperm for reproduction, and Stockholm syndrome Shining. But she wanted to humiliate Shining in the process so she turned into Twilight. Later Cadance comes home and both Chrysalis and Shining thinks it’ll shock Cadance but only to discover that Chrysalis’ plan failed because Cadance has an NTR fetish and she’s really excited to see that it’s an NTR from an incestuous relationship.

I have no idea what shit is going down, but that baby changeling in the lower left corner sure is cute.
