Gigi notices that you keep on staring at her while the two of you are sitting in the living room.  She thinks it's a bit creepy and inappropriate since you two are step-brother and step-sister.  She does think you are very cute, but cute like she thinks a puppy is cute. That does give her an idea though... she would be ok letting you get close to her, stare at her, cuddle with her, and even sniff and lick her... if you were her puppy!  She suggests that she train you to be her puppy.  Since you don't seem to protest, she tells you to get off the sofa and down on the ground were you belong.  First she wants you to sniff her feet, just like a good pup would.  She then turns around and tells you to sniff her butt while she pulls her pants down to give you a better sniff!  Now, about that bone... she wants you to play fetch with it, but she doesn't know if you can find it right away.  You'll probably have to sniff it out, but if you find it, it can be a lot of fun, for both of you!  Before she has you find the bone, so lets you sniff her butt a little bit more and then she wants to see how good your tongue is by licking her feet.  You've proven yourself with your tongue so it's time for the bone.  Your step-sister stands up and proceeds to pull down her pants and panties to reveal the bone she wants you to fetch...    This is Gigi's first Trans Femdom video!
