Her cock was not the only thing she wanted to have showering her, so she changed the word "large" with "leaking".
The second she hit enter on the app screen, her other hand clamped down on her bottom-right nipple as if her life depended on it.
Her nipples were no longer just sensitive, no. They were more like additional small dicks, sticking straight out of her breasts, but way softer. Now swollen so large with milk that the ones she hadn't in a death grip were drooping low and sagging against the breast they stuck out of.
Her right hand was filled completely with sticky flesh she just couldn't stop squeezing.
And she was rewarded.
A near torrent of milk was spilling out of her right hand, firmly closed around her nipple. Still, it was less like the eruption and extacy of an actual orgasm and more the feeling of massaging a particularly sore spot after a workout, or finally going to the bathroom after a long day in the office, utter relief. She didn't hesitate long and soon her left hand joined her right, taking a nipple for it's own and massaging it like her life depended on it.
She could no longer call the nipples, these were teats, plain and simple.
Her cock meanwhile, despite not being stimulated, stood tall and proud, poking the air and swaying in time with her breath. She wasn't cumming, not yet at least but the feeling of clutching at her teats had her cock constantly trembling and on the brink of orgasm, leaking pre-cum in concert with them.
As her hands were busy tending to her breasts she could finally look at what exactly her change with the app had done. Her new teats were the obvious change, having grown larger, thicker and more prominent. Even the ones she wasn't busy handling were leaking milk onto her breasts in large amounts. Seeing this she switched her hands around, trying to get at each breast at least somewhat and was immediately rewarded as a pressure she hadn't noticed before abated.
Her breasts had also changed. They weren't small to begin with certainly, but by filling them with milk in such amounts that her teats were even leaking without her involvement they had to adapt nonetheless. They were overall bigger, maybe 2 cup-sizes, and curiously perkier than before. The milk inside of them giving them more structure, bloating them like balloons and highlighting thick veins that crisscrossed all over them. They were also much heavier, the fluid inside making itself felt, though not uncomfortably.
Soon she could no longer concentrate on just looking at her breast but also simply had to feel them. Her hands glided from teat to teat, sometimes lingering to spread her milk over her breasts, the fluid feeling like oil on her gravid breastflesh, drawing attention to the dark blue veins as they were supplying all her breasts needed to keep her production up.
She pushed all four of her breasts together, eliciting a moan from her, her whole front gushing at once with fresh milk and splattering her dragon dick liberally with it. She could no longer contain herself, she simply had to taste it.
She had no trouble guiding one of her faucet like teats to her mouth, so long were they. Immediately after closing her mouth around it she knew she had made the right choice, fresh delicious milk filling her mouth and driving her to start suckling in earnest, all the while still milking herself as if she were a dairy cow.
...
Regretfully she soon had to stop drinking her milk, simply too full and unable to stuff anymore inside herself, regardless of how good it tasted. She felt bloated as her teat popped out of her mouth she noticed that while she was focused on drinking herself into a coma her tail had taken the initiative and was servicing her unattended cock, sliding up and down her rock hard rod and causing even more pre to spurt out of it.
The flow from her breasts had not abated and her teats were still spilling milk all over her front, but the pressure was less insistent and she could get away with removing her hands from herself for a time to maybe deal with her still hard cock.
Or maybe... she could generate a new sentence with the app, who knew what she could change?
