Ultimately, you decide to change Jessica's mind for your first act. She already has a rockin' body, so there isn't much to improve. Indeed, the past year has been rather interesting, living with her E-cups and tendency to wear tight, revealing clothing. The past 20 or so years of her life she had been living with just her mother, so it didn't really cross her mind that traversing the house in a curve-hugging tank-top was inappropriate. Dad had only you, so he figured this was normal behavior, and your step mom didn't mind it much either. You had no qualms either, as her choice of attire lead to a bountiful amount of cleavage shots.
Getting acquainted with her chest had been a dream of yours, and if this wand was what it claimed, it was time to fulfill that dream. Wand in hand, you enter the room and take a seat on the opposite side of the couch. Her eyes are glued to the TV which means she doesn't notice the wand aimed directly at her head. You hesitate for a moment, unsure of whether to continue, but finally gather your courage and push through. You mentally command that "Jessica will not know I am here and will be oblivious to me feeling up her body". There is no outright change, as it was all internal, making the next moment of finding out whether it worked worrisome. Just grabbing at her tits would get her pissed if it didn't work, so you take it gradually.
To begin, you cautiously slide across the couch, taking up less and less room until you are sitting side-by-side to her. She doesn't seem to respond to the invasion of personal space, so you take it up a notch. With an open palm, you place your hand against her shoulders, and still no response. Things seem promising, so you decide to go for it all. Extending a finger, you slowly press it into the side of her large tit. The digit sinks into her fleshy mound in a manner that she could not simply ignore had the spell not worked. Despite you worries, her face is still glued to the screen, more focused on her stupid shows than whats going on with her body.
It was time to go to town. You squeeze your body behind her position on the couch, taking advantage of a gap she left, and essentially begin to spoon her. Even you would admit this was sort of odd, but your libido was too strong to care. Her t-shirt disallows you from reaching them up top, so your hands go through the bottom of her shirt to reach her massive love pillows. Your hands quickly reach her tits, and since she isn't wearing a bra, you grasp as much flesh as you can; they're too big to fully grasp, although you don't mind. The softness of her flesh is so much better than you'd imagined. You had had girlfriends before, but never this big.
The fun comes to an end when she lets off a moan. Panic sets in as you think that its possible she was too confused to respond earlier rather than actually unaware, meaning that Jessica would most certainly freak out. You pull forward to look at her face, expecting shock, but are greeted by a look pleasure. It seems that while she may not sense you, the kneading of her tits is sending sensations throughout her body.
This gives you an idea. She's enjoying it, so why not take it to the next level?
