Well, whatever it is that got her, it clearly filled Dashy enough to make her pregnant! Hopefully she can teach her future tentacle child to be a productive and helpful member of pony society, like Twilight did for Spike!
Or she can start her own sex studio and/or store, with a very unique staff member~. Perhaps Fluttershy can help!
Many thanks to Pabbles for providing us with the tentacular art we got today!
