Here is the traslation:  
Rarity: D… Don’t worry. It’s okay. Rarity is here.  
Rarity: It’s fine. It’s all fine…
 
(Sweetie Belle keeps scared herself)
 
Scootaloo: Hey, Sweetie Belle, let’s play with us!  
Apple Bloom: Hello!
 
(Rarity sighs)
 
(Sweetie Belle is afraid because of the page contains sexually explict content(The page says the poster wants to do sexual relationship with Sweetie Belle without condom)
