Emerald groaned at the suggestion. She wanting to at least ENJOY the sex, but, after hearing you say you'll give her bigger breast in return, she eagerly agrees! In Dragon Culture, bigger is simply better! And everyone respects it like its law! She braces herself as your barbed kitty cock pushes into her asshole, she nearly screams as the barbs prick and rub against her skin, however, her skin doesn't stretch or scrape like a humans does. She starts gasping, actually enjoying your cock slightly more then she would have a humans, too bad she decided to get it into the butt. She groaned and moaned as she got fucked in the ass, raising her tail, wanting her so badly too over come her sister. Her skin while tough, is actually rather soft. Her chest being extremly soft and gropable, she gasped as you did so, moaning and blushing as she got horny from you touching her.<br/><br/>Ember giggled watching this, and hearing what you have to say. "<strong>Oh yes! Make the slut flat chested! She is after all my Assistant, and little sister! And its my job as the bigger sister to have the bigger chest! Besides! ONE of us has to have a flat chest! Some perverts like small chest, some like big chest! Nothing can be gained from two people with large chest. We'd get twice the customers if one of us was cute and adorable rather then busty..."</strong>She looked both ways and made sure her sister wasn't listening before whispering into your ear<strong> "That's why I've been casting spells to keep her from physically aging! So she stays cute and small chested!"</strong>
