Since you were caught sniffing her dirty lingerie again like a pu ppy, your step-Mommy has been training you to be Her pu ppy. Your behavior has improved so she will let you stay in her bedroom as she changes clothes for her date.   As she strips out of the white panties she has been wearing for two days so knows you really want to sniff them, but not just yet. She puts on a sexy pair of black lace thong panties and tells you to crawl over to her and not only sniff the front of her panties, but she turns around and commands you to stick your nose in between her butt cheeks and get a good sniff there! She then proceeds to put on a matching sexy black lace bustier and then slips on a short, see through little black dress that leaves nothing to the imagination, not that it matters because her date will probably just rip it off of her and take care of her sexual needs, that no pu ppy boy could satisfy.  After her date if she is feeling generous, she will let you crawl under her dress and put your nose and tongue to work... and you might even get her wet panties as well!
