The normally peachy skin of the elf had turned an utterly bright red, and Krystal could swear a small amount of fume was rising from how embarrassed she was getting.  Still, she tried to stammer it out.  "I mean... it feels really good... but I don't think it's fun... just really... really... good..."  The flattened elf was slowly getting herself hot and bothered by the conversation, and Krystal could see a slight motion in the girl's small, pink nipples as they seemed to rise up just a bit.
