She moaned to herself as she groped her huge tits - feeling the fabric of the bra, as tight as a drum across her chest.
Her cock started to swell and rise off the bed, her balls - previously the size of goose eggs, started to churn and swell, growing into heavy baseballs that slapped against her thighs as she started to sway back and forth from the sensations coursing around her new body. She reached down with one hand to feel her new balls and a big dollop of pre-cum slurped out of her huge cockhead - which she quickly reached over and scooped up, sucking on her fingers to taste the delicious slippery liquid.
Her breasts groaned and tingled, the bra creaking ominously as the magic fluid started to work its spell on her already heavy chest. She massaged her nipples through the bra - feeling them press aggressively into the material. The more she played with her breasts, the more it felt like they started to firm up even more - the bra creaking every few moments, as new growth, accompanied by little pin pricks and popping feelings inside her breasts, washed over her in delicious tingly waves.
Her beautiful cock, having now risen up to the level of her mouth, with its graceful taper, and tennisball sized mushroom head, swayed back and forth - its motion capturing her attention like a snake charmer's dance. Reluctantly, she took one hand off her breast, and guided her cock into her mouth, jacking the upper reaches slowly - coaxing more delicious pre-cum onto her tongue. Her tortured bra increasing its protestations as her breasts tingled and started to swell further, bunching up under her chin like rising dough. Her balls continued to swell, reaching the size of grapefruits and the maddening pin pricks inside her breasts finally stopped, only to be replaced by the feeling of fresh swelling - a filling, sloshing feeling.
This riot of new sensation cause her to orgasm once again, and she locked her mouth over her cockhead - struggling to swallow down the firehose of cum from her new bigger balls. Her breasts immediately lept larger and with a loud creak, and many popping sounds (and no small amount of pain), the bra's four hooks all bent straight from the pressure, and it shot off her chest, halfway across the bed (having caught on her cock along the way, slowing its path). Her breasts surged forward and down, nearly to her navel - wobbling back and forth, each easily the size of a gallon of milk, and still swelling by the moment as the realization of what just happened hit her. She had burst out of the bra, and that made her cum even more, now shooting directly into her stomach, without having to swallow, her breasts simply filled like a waterballoon left on the tap. Quivering heavily and sloshing as they filled with cum, and now, apparently with milk - getting firmer and firmer - her huge cock now trapped between the growing masses of boob flesh.
Her nipples now wine dark and larger than she remembered were the objects of her affection - both hands grasping their thimble sized ends and massaging the still swelling breasts as she bravely swallowed the last of the huge load she had ejaculated. Her breast trembled larger, their bottoms resting on her thighs now as she kneeled on the bed. Letting her enormous cock flop back down - she leaned her head back and took a deep breath - feeling her breasts swell larger, and larger as the milk ducts worked overtime to fill and overfill the huge breasts she cradled.
She felt her breasts start to lift off her thighs, as they swelled tighter with milk. Engorging and tightening almost painfully as she kneaded her nipples now hoping for release to the filling sensation, as much as for pleasure. Her breasts stood proudly out from her chest now, supported by the tight skin and seeming gallons of milk in them. She could barely reach her nipples with her breasts this full - her arms entirely wrapped around their swelling mass, and she sat back on her heels and gasped in pleasure as the first rivulets of milk started to dribble out of her nipples and off the shelf of her breasts onto the bed in front of her, wetting her cock, and causing it to start to fill with blood again, her grapefruit sized balls gurgling in pleasure and starting to swell again.
