"Babe, can you hand me another bottle? I'm still way too small."
Your girlfriend had found out about your special interests. There was a time when she was weirded out by it, but she's since seen the light. Now she's even more into size than you are (to a slightly concerning level), and is determined to make both your fantasies real.
One pill at a time.
I can still remember the night that my fantasy became our fantasy. I was scrolling on my phone, as I often do before settling into bed, when I could hear the shift in her breathing. Her breasts sat heavy on her chest, easily doubling their previously impressive size. She had thought her H cups were big, but these gargantuan breasts would have made her old self look puny. They dominated her torso, her pale skin covered in a web of veins. Her nipples had grown, too, easily as thick as my thumb, practically quivering as arousal overwhelmed her. Her sudden grip on my arm dragged me away from my phone and, god, the lust in her eyes when her gaze met mine. "Fuck... Fuck... They're so... They're so sensitive. I can feel everything. I can feel the fucking air. It's going to make me lose my mind." Her attempt to placate me, to get me riled up, was a little obvious, a little forced, so I decided to get back at her by leaning in and gently blowing over her breast. I got maybe a second and a half into it before her whole body tensed and she let out a deep, desperate moan, clasping her hand over her mouth as her hips writhed beneath her. Unless she had been taking some serious acting classes without my knowledge, the orgasm that wracked her body was genuine. Sweat trickled down her cheek as she met my gaze again, her eyes glazed over, her chest heaving. Her mouth opened and closed a few times, swallowing to wet her throat. Finally, she managed to whisper a single word: "Bigger."
It wasn't uncommon for her to throw herself wholeheartedly into whatever she was doing and this was no exception. Bottles seemed to empty faster and faster, the growth accelerating just as much. Some women would be panicked to wake up and find themselves unable to heft their own tits off the bed. My girlfriend decided to spend that day on top of them, bucking her hips against them. The pleasure only encouraged her, narrowly managing to get her out of the house before her tits could no longer fit between door frames. Putting up a party tent in the backyard seemed like a good solution, but the daily, unending growth made it obvious that it was a temporary solution at best. I tried to talk her into maybe slowing down a little, maybe even stopping, but she just laughed. Neither of us really wanted it. I was just afraid. She wasn't. "Come on, baby. We've both read all those stories you've bookmarked. Now, go get my another bottle so I can outgrow this tent. Then there's the block, the neighborhood, the city..." She giggled, a ripple moving through the wall of tit that rose above her head. Almost six feet out in front of her, her nipples stiffened. "Ask yourself: haven't you ever wanted to live on a planet of tit?" I felt a little numb as I handed her the bottle, watching her greedily swallow the pills. I genuinely couldn't tell if that was a joke anymore. And, worse, I liked it too much for it to really matter.
