just then the door opened. the doctor walked in and walked up to riley. "hello riley, do you want a treat?" he said. riley just looked at him in astonishment. "who does this guy think he is? does he really think im an animal?... what kind of treat?" riley's ears began to perk up. the doctor held out his fist slightly open. riley crawled up to him and sniffed his hand. suddenly she felt all happy and dumb. the doctor opened his hand and riley ate the green leafy stuff he had. she fell to her back and pawed at the air feeling very content and happy and giggly. the doctor was kissing her nipples and dry humping her. before the doctor even knew what was going on riley's tail had undone his pants and pulled out his cock and was pulling and squeezing it. riley was still kind of giggling and spaced out. she stood up pulling the doctor up with her. she turned away and started sleepily walking away. her tail leading him by his cock behind her. the doctor turned her around and pushed her to her knees and commanded her to suck. she looked up at him dreamily and began licking it. the moment she got the taste in her mouth she focused. she could remember the taste where had she tasted it before? she tasted it again. she still couldnt place it but she knew she wanted to have more! she started sucking and deep throating it. the doctor flinching the whole time because she had acquired some sharp little fangs somewhere down the line. riley began to lose interest in this taste and turned away to find something else to do. the doctor didnt mind in fact this was just what he wanted. her luscious ass waving as she crawled away from him was too much to bare.
