Spike has had a long time to grow up, and now that he's eighteen he's found that he has been experimenting more and more with his body. Particularly in... only mildly horribly revealing outfits when Rarity isn't home. He isn't sure why he enjoys the feeling of them, only that it makes him embarrassed yet enticed. While he's attempting to play with himself, however, a certain demi-god decides it's time to have some fun of his own. Especially, as Discord put it, with those big, chubby cheeks.
