I like this A ALOT

-straight sex

-male pony parts aren't massive

-look like they're probably in a relationship

-random male OC lets me insert myself into the situation

-generally well done and cute

now... why are they doing this on a park bench?

Considering they walk around in public naked, they have no nudity taboo. Maybe public sex isn't as heinous to them, though possibly it's considered taboo: the way we would consider public nudity. Rainbow Dash's reaction in the background certainly suggests this is a noteworthy event.

I would assume they wouldn't do this thing in public regularly...
but I guess it works

maybe they're just being really really spontaneous?
IDK
all I know is if I were to take this image and change the male pony's mane and tail to be red and orange it would basically be my OC. I'm really really tempted...
