"Well hey there..." She steps back, making room for RJ to step inside. Not wanting to offend, RJ stepped in immediately, Anna shutting the door behind him surprisingly gently."So... you live downstairs, right?"
RJ nodded. "Uh, yeah, my name's RJ, I work with your sister, Sabrina."
Anna suddenly grins toothily, bending down and offering RJ a handshake, which, again, not wanting to offend, he accepts. Her grip is tight, but not crushing.
"So you're the human Sabrina told me about. Hmmm..." She suddenly pulled RJ closer, giving him a testing sniff. "Heh, I guess you two haven't hit it off."
RJ blushed a bit, surprised at the forwardness of Sabrina's large sister. "H-Hit it off? We're just friends! A-And she asked me to check up on you."
Anna's tail began to wag, as she looked RJ over. "Just friends, huh? Well then..." She sits back, her mass completely covering the door RJ had come in through. "Why don't you stay awhile? We can have some fun and get to know each other." She pats her massive gut as she talks. "Course, if you need to be anywhere, you could also take a short trip through me to get out the door, if you want, I know I wouldn't mind."
RJ's pretty sure she isn't serious, though her wagging tail suggests she has something up her sleeve, he wasn't sure what to do.
