Giantess, Transformation, Growth, SFX, Brunette, jeans, barefoot, bare feet, glasses, tails, heavy breathing, from shy and timid to powerful and more. Jessica always wondered exactly what her friend did at her job. She had asked many times, but her friend would only say that she wasn’t allowed to talk about it.  Jessica overheard her friend and a mutual friend, talking about a brand new spray for him that they are going to have clinical trials on next week. Jessica's friend calls, and after making sure that she wouldn't be home for a while, she decided to go check out the spray for herself. She knows exactly where it was hidden, and it's just going to sample a couple of sprays to see if anything actually happens. The sweet, smelling mist is so alluring that once Jessica sprays one small pump, she cannot resist, spraying herself a few more times. She looks at the bottle and says that there won't be a problem because her friend won't even be able to tell that any of it is missing She notices that her clothes begin getting a little tighter and tighter as time kicks by and then she becomes well aware of the fact that she is definitely growing much larger. It's as if she feels more power with every growth spurt that she has, and she actually loves the feeling. You will see her grow on screen and watch her shirt getting tighter until she is topless. She then realizes that her friend will be home soon and her only concern is hoping that she transforms back into her normal size before she arrives home.
