some do Twilight, seriously get with the times.

@DanielTepesKraus
 
You nailed it. That’s actually the story I had in my mind when I drew this. I literally thought, “How would she react if she saw all these drawings of her and her friends with a penis?” She’d probably react in a scientific fashion before being appalled. The wingboner was just exploring the idea that she may be a little turned-on by the thought.

@DanielTepesKraus  
Thanks alot, now I want it.

@Lupin Quill  
I just realized how much I want a comic series of Twilight reacting with shock and horror to porn stuff that isn’t actually real. I mean like getting out and out outraged by it because it isn’t plausible or realistic.
 
“This species makes no sense! Why would these cephalopod creatures try to assault mares?!”  
“Twilight, it’s just–”  
“It’s just something that doesn’t make sense, Spike! How do they see, or breathe?! How do they have the strength to restrain ponies like that? HOW DOES THEIR SPECIES WORK?!”
 
“But if she loves her, why did she shrink her down and swallow her? That’s not love, that’s cannibalism! And how is she surviving inside the stomach without suffocating or being digested?!”  
“Twilight, you remember when Applejack was shrunk by poison joke and how force-fields are a thing, right?  
“Silly Spike! That’s a pegasus! She can’t use magic!”
 
“That poor stallion! Look at that nasty gash down there where his privates should be! He shouldn’t be smiling and aiming it at me like that! He should be at the hospital!”  
“Twilight, that’s a vagina.”  
“Silly Spike, mares have vaginas and stallions have penises.”  
“But the mare in that picture has both.”  
“Both?! BOTH?!”
 
“SPIIIIIIKE! HELP!!! THIS LAMIA PERSON PUT BREASTS ON A COLT!!!”

Since it was so easy, I just made the edit myself. https://derpiboo.ru/1046400

Derpibooru challenges Twilight’s encyclopaedic knowledge of biology.

I suddenly think this would be much funnier, and would like to see it edited, with a question mark instead of an exclamation point.

Surprise, Twilight!! You’ve got a dick now! :D
 
You’re welcome.

@DanielTepesKraus  
“Eeee _eeyup..”

It’s not hard for a mare to get a cock, Twi. You just need some surgical tools and something to knock a stallion out.
 
“Hello Big Macintosh? Say… does this cloth smell like chloroform to you?”

If you can’t already tell; this was done tongue-in-cheek. I don’t care what people draw.

@furbyguy  
I’ve done that to a friend who doesn’t like futa. Needless to say, all I got was a proverbial roll of the eyes.

I don’t personally like futa either and I can’t draw BUT NOW I HAVE TO DRAW A WHOLE BUNCH OF FUTA MARES JUST TO PISS YOU OFF

I’m pretty sure mares have dicks.

Careful there Twilight, people will see that as a challenge.

But they look so good on them!

Pfft. I’ll put cocks wherever I want. Male ponies, female ponies, in my bum, on homework assignments, in museums

You’re wrong. Fluttershy has a few in her coop.
