“Julie the short curvy girlfriend is nervous to strip in front of you”
you thought through a few of the options this sentence offered you... you could make her excited, instead of nervous, to strip for you, you could make her something more, or less, than Charlie's girlfriend, like a slave, or a pet... or maybe just change her name to something embarrassing. You smirk at the thought of her legal name being Blowjob, or Fuckdoll, or Cumrag... Introducing herself at parties, filling out job applications, even ordering drinks at Starbucks, nobody suspecting it was anything but a normal name, given to her by her parents at birth. You'd have to try that sometime.
Julie gave you a confused look, pausing as she began to pull on the hem of her soggy shirt. She seemed to notice your expression, or perhaps the way your footlong was beginning to tent your robe. You decided to try something creative.
“Julie the short curvy girlfriend is nervous to shrink in front of you”
Her expression immediately changed to one of panic, and she sniffed at the drink you spilled all over her shirt and jeans. "Wait, is this... is this orange juice?"
You nod, excited and curious for what's coming next. "yes, dear, is that a problem?"
You notice that Julie is already a few inches shorter, and her wet clothes are hanging a little loose on her curvy body.
With a surprising urgency, she started stripping - it seemed like she wasn't nervous about that part any more - struggling with clothes that were rapidly becoming too big for her, and splattering little droplets of juice around the laundry room as she did. Finally naked, you could see her ample breasts and curvy hips still damp with juice, glistening in the fluorescent light. She was much shorter than you to begin with, but now the top of her head was well below the bottom of your breasts, and still sinking. "I'm allergic! I'm having a reaction!" she exclaimed. "I need to rinse off or I'm gonna keep getting smaller! Where's your bathroom?" She was shrinking faster now, and she was already straining her neck to look up at your face, still totally unconcerned with her nudity. "Oh my! isn't that a surprise" you remark with feigned confusion, amused at how the app had made your changes a reality, inventing some kind of impossible 'shrinking allergy' out of whole cloth.
Julie was jumping up and down now to get your attention, paying no attention to the way it set her round, juice-soaked breasts in motion. "Mrs. Smith! I'm serious! if I get much smaller, I'm going to have to miss school! I- oh." She stopped mid sentence, noticing that she was now eye-level with your tremendous cock, which was now rock-hard and tenting your bathrobe, threatening to come uncovered with one wrong move or the slightest gust of wind. Even to a normal-sized person, your log was absolutely enormous. From Julie's three-foot-and-falling perspective, it must have been downright terrifying.
You sat down on the floor of the laundry room, lowering yourself to her level, and enjoyed the helpless expression on her little face, as well as the cool breeze on your eighteen inch rod as your robe gave up any hope of concealing it. It stood like the tower between you two, and Julie stared at it with a look of abject terror her height dwindled further. "P-please, the shower..." she pleaded.
"Down the hall, and to the left," you whispered with a smirk. Julie took off like a shot.
You stood up slowly. You laughed ass you realized that, at her two foot stature, it would take her much longer to reach the bathroom, even at a sprint. By which time she would be even smaller. Following after her at a casual pace, you generated another sentence.
"Julie is traumatized by the callous way you reacted to her shrinking, not to mention the sight of your enormous hard-on."
Well, maybe you went a little to far. At least the solution was simple.
"Julie is aroused by the callous way you reacted to her shrinking, not to mention the sight of your enormous hard-on."
