My Master calls me little one. He has from almost the beginning. He doesn't deviate very much and I worry when he doesn't call me that! He often calls me his slut too, adding other words such as pain, ass, cum before the word slut. It was my birthday last week and he called me his little birthday slut. ~giggles~ It made me laugh. It was absolutely fantastic! I can echo the sentiments though. If anyone else called me a slut I'd probably be pretty upset, but when he says it I just smile and say "Yup. Your slut!"
