Misty is excited to plan Valentine's Day with you. She is looking forward to spending a romantic evening with you, exchanging gifts, and indulging in each other's company. As she sits across from you, her eyes sparkling with anticipation, you can't help but feel a mischievous urge. Without warning, you reach over and grab a long cylindrical hose, quickly placing it in her mouth. Misty's eyes widen in surprise, but before she can react, you begin to pump into the tube. She lets out a muffled cry as her cheeks puff up, and you can feel her struggling against your grip. But you don't stop. You continue to pump into the tube, watching with glee as Misty's body begins to balloon in size. Her belly starts to swell and inflate even further. The fabric of her shirt strains to contain them, and you can see the seams starting to rip. Misty's eyes bulge up, and her mouth fills up with her own saliva from the intense pressure. But you don't let up, vigorously pumping more air through the tube and into her mouth. Her chest continues to expand, growing rounder and bigger with each passing moment. Watching your girlfriend inflate before your eyes, her body gets fuller and rounder, as you can see the air pressure starting to fill up different parts of her body, but mainly on her belly. You can't tear your eyes away as her tank top is now stretched to its limit, seeing it starting to tear as it struggles to contain her ballooning body. But you don't stop pumping air into her, enjoying the sight of her becoming bigger and rounder by the second. You inflate her until she is almost twice her original size, her belly expanding in seamless proportions. And as she looks at you with eyes bulging and mouth-watering from her own drooling saliva, you know that this is going to be a Valentine's Day she will never forget.
