Becky always had fun with her snapchats, often sultry, teasing, and seductive. But never before had she sent you something quite so… overt, unnuanced, or needy. The usual, string of increasingly suggestive shots, drawn out expertly with some unknown skill of erotic timing- was completely skipped, in favor of sending quite a risque picture of her new lacy bralette, with the accompanying text of “Please come over as soon as you get this, I need you”. After a buzzed jaunt across town and a nervous elevator ride, you found yourself in the long, wide shadow she was casting from her apartment window.

“Oh, you’re here,” she said, turning with a half-smile into a sultry pose. She hadn’t been devoid of curves before, and she had always been a striking looker in other regards- But now her entire bottom half was thickness personified. Her broad, luxurious hips flowed into immense, round cheeks, which rested atop vast, but plush looking thighs. Her lingerie was straining, and as the straps of her garters were forced a little further to the side with each tiny movement, you could almost hear their protest. “Oh, come on,” she said in a mock pout, in response to your silent confusion. “I told you I was going to keep working on my figure.” Before continuing, her eyes unfocused in sudden, internal distraction. Her knees buckled and with barely controlled descent, and you as she slid shuddering into a fetal position on the floor. She bit her lip, breathing heavily in the grip of some unseen passion, she practically oozed across the hardwood with suppressed ecstasy.

It took several more seconds for Becky to finish. She had spent a long few moments in what looked like repressing the urge to buck her pelvis, her every movement quivering across hundreds of pounds of womanly flesh on the floor. When she finally managed to focus her eyes again, panting and nearly breathless, she stretched out and tried to mock some semblance of composure. The shock of her indulgent display fading, it was now undeniably obvious how much she had immediately grown. The lingerie had strained to the point of tempting failure, her panties had all but completely vanished from sight and the uncovered gaps in her thigh-highs ever further under the onslaught of ballooning, creamy flesh behind it. “Finally one of those mail-order diet pills worked,” she confessed, looking a little amused and letting out a tiny little trill of pleasure at her own self-inspection. With visible effort, she floundered with her new mass on floor a moment, and finally, with some struggle, rocked herself back into a sitting position. “Side effects, though,” she murmured breathlessly, her eyelashes fluttering as she gripped the window frame for support.

Her legs seemed plenty strong enough to accommodate all the mass. How much of her strain was the actual weight of her new dimensions, unfamiliarity of her new volume, or the residual weak-knees from the display before- you could only guess. The window she had been partially occluding before now be completely eclipsed if she managed to stand, and you watched her hips thighs broaden even further. She was now rivaling the dimensions of a two-seater couch, and the plump curvature of her improbably-pert cheeks was still visibly expanding backwards over her heels. “It’s been happening every couple minutes,” she said. “Or when I move too much, or when I slide my thighs together too roughly, or when I think about how good I look now.” She ran her tongue along her lips thoughtfully. “I think I need some help to get it out of my system. I think I need you, lover.” She leaned over, and pulled you against her with some startling tenacity, forcing you to grab around her cartoonish hips. Despite the perfectly-round shape of her bottom, your fingers sank into doughy softness, distorting her cheek until your forearms were almost completely engulfed in bulging, warm butt-flesh. “What do you say?”
