If Twilight was a pony while they had sex then Flash wouldn’t have had that reacted that way.
Then again, sometimes a man doesn’t give a fuck when he’s horny….
@Twilatron217 We kind of have an entirely different tag for when a human and a pony go at it here… It has something to do with action, humans, ponies, and a position with respect to anothers position.
At least in the context of derpibooru, there is a difference between “bestiality” and “interspecies.” Interspecies is sexual stuff between sapient beings of different species, whether those sapient beings are ponies, humans, griffons, diamond dogs, etc. The “Bestiality” tag is for when a sapient is having sex with a non-sapient animal, like a pony having sex with a timberwolf, a phoenix, or a regular horse. In this case, it’s the sapient human Flash Sentry having sex with the sapient pony Twilight Sparkle, so it falls under “interspecies,” which we have.

Even if it were the truth, there’s a much nicer word for it anyway: zoophilia. But since this is intercourse between two sentient creatures, it’s not. If you really want to call it something, then you should call it human -iality, as Flash was the nonconsenting one here, not the “animal”.
