New Technology [Weight Gain/MGTS]

    "Are you sure you want me to get bigger? You know most of this is going to go to my belly, right?" she warns, hesitantly.

    You excitedly nod affirmative. 

    She sighs, not entirely convinced her new figure will be worth abandoning the remnants of the beach-bod she had worked so hard for. Giving you a stubborn glare, she repeatedly taps the touchscreen's "+5 lbs" button. The tablet she's holding hums with strain, and you see her garments gently stirring, as her figure begins to swell. 

    She looks mildly chubby, and she gives herself a couple experimental pats and pinches. You're completely awestruck at her 50 lbs gain, her once painfully flat chest now sports some healthy looking C cups, her torso looks a little more healthy, and she seems at least three inches taller; putting her at eye level with you.

    "Hey, you know this isn't so bad.." she says, reveling in her newfound height and looking a little mischievous. She looks at you, and then the device, and without any waste of time she quickly taps the "+50 lbs" button a couple times. The device hums loudly as you first stare speechless at her brash move, and then her developing diameter.

    You're further pushed into speechlessness as she swells faster now, beyond a comfortable chubbiness into absurdly rotund proportions. Her breasts balloon and bulge against their restraints, her stomach inflates with soft adipose tissue, her thighs and butt swell out, and her whole frame grows a foot taller to support the new mass. She experimentally twists and turns, pushing her huge belly out. She's at least twice as wide as before, and it doesn't look like you could reach fully around to unbuckle her straining bra if you tried; however with how strained the brassiere looked, that problem would solve itself with a sufficiently deep breath on her part.

    She approaches you seductively, pushes you back onto the bed and climbs on top of you.
You're completely overwhelmed in her new, warm softness, and greedily feel up as much of her new size as you can, lost in a lustful haze..

    You're lost in your passionate kissing and groping when you notice a slight movement to your left, and a strange loud humming begins. You crane to see that she's rapidly tapping the "+100 lbs" button..
