At the sound of Jeff's final, decisive *CLICK* Jennifer felt a wave of heat wash over her. "Oh god! What..." she sat straight up on the mattress, her legs sliding down as she frantically fanned her face to try to dissipate the sudden flush suffusing her body. It wasn't helping though, and her previous shyness was apparently forgotten as she gripped her shirt and pulled it off over her head. Her chest was heaving in her modest cotton bra, and Jeff found himself shocked into stillness at the sight of his girlfriend panting topless on his bed.
As the flush finally began to fade, Jennifer slumped back against the wall with a slight thud. "Did I... did anything change? That was INTENSE, Jeff!" Suddenly, she realized could feel her shoulder blades sliding upwards against the cool surface behind her - oh! it had just begun! she was definitely growing! Was Jeff making her older and more mature, like him? Gazing down at her body, she watched as her hips pushed outward, straining her jeans as they grew wider, making her waist appear tinier by comparison. She squirmed, adjusting to her changing body and feeling more cushioning underneath her - her buttocks were much plumper than her former flatness! Jenn struggled to unbutton her jeans and slide them down her hips before they burst.
There was a pulsing sensation in her chest, and she realized that her boobs were rapidly enlarging, quickly becoming twice their normal size, slightly more pendulous, and feeling... fuller? As she watched, wet patches blossomed on her straining bra cups, and she was momentarily frozen with the realization that her breasts were leaking... milk?!
Suddenly, her gaze was drawn further downward at the sight of something roiling beneath the skin of her stomach. Raising her hands to clasp the slight pooch just below her abs, she was shocked as they were pushed out rapidly, her belly expanding forward and obliterating her once-thin figure. She could feel a fluttering sensation from within the huge mound, and a sharp jab kicked against her left hand!
"Ohmygod Jeff... am I... PREGNANT?!" her wide-eyes lifted from her enormous belly to find her boyfriend slumped in his desk chair, his right hand absently rubbing himself through his shorts.
