Smolder and Silverstream are best friends - or maybe more than that, as Smolder has a big crush on Silverstream but doesn't want to admit it. They hang out one night, and Smolder suffers a few embarrassing moments, but Silverstream gets her to laugh them off, unashamed of doing them herself. Smolder soon realizes that Silverstream might feel the same way about her, leading to more moments, which turn kinky, wet, and sometimes smelly.
Contains: Farts, wetting, spanking, underwear, olfactophilia, and soap/washing. The last two are light in Chapter 4 and prominently featured in Chapter 5. Also, probably low quality and stretchy/ludicrous scenarios, and I think I got carried away with the fetish stuff yet again.
Characters are humanized, but not EqG, they have the standard white human skin, but the same hair color as the show, Silverstream has long hair in her usual style, and as for Smolder, we'll say she has neck length hair, I've seen that quite a bit. Also both Smolder and Silverstream are 19 in this story (in case they weren't 18 before, which is likely the case with Smolder).
If you really like these characters but hate the fetishes, please ignore and don't subject yourself to depictions of them that disgust or offend you. Keep loving the original, canon, dragon and hippogriff Smolder and Silverstream or clean human depictions of them, don't let the fantasies of a guy with some weird fetishes change the way you feel about them, and don't take this story too seriously.
Also I don't write Smolder or Silverstream often so forgive me if I didn't get them exactly right.
