Realizing that she was still able to breathe despite the loss of her nose and mouth through the odd location of her navel, Hillary (pleasurably) pushed apart her rows of breasts, squishing them just enough for a small amount of milk to dribble out of four of them. Her belly button was replaced with a sort of Oreo-sized, toothless, sphincter-like, pseudo-mouth opening. Testing it out for a bit, Hillary closed and puckered it and then opened it to an extremely wide degree (to the size of a watermelon's width) before hurriedly closing it. Lolling her new extendable tongue nestled in the maw, Hillary then tried to speak - to no avail. The only sounds that she could produce were wet smacking ones.
She tried to stand, grunting as her back and abdominal muscles straining to hold up her huge jugs.
Halfway through her dazed, painful trip from the kitchen to her apartment's sofa, the familiar pleasure resurged again on her dribbling nipples.
Before her eyes, all six nipples grew into impressive cylindrical forms before tapering off with a mushroom-like head and gaining sparse veins.
And so within just 40 seconds, Hillary had gained a new grand total of eight penises. All of which were rock solid, throbbing and dripping with need. Her nipple-penises were practically leaking a bumpy stream of "milk" before the red-faced, sweating girl finally intervened, and shakily gave her two topmost breasts' penises a light tug.
She arched her back and gasped with her navel maw as those two penises' testicles quivered before "ejaculating", releasing torrents of a nutritious mixture between breast milk and semen into a high arc in the air, before either getting stuck on the ceiling or going splat on the floor.
She couldn't get enough.
Hilary tugged on her four remaining breast penises and began to deftly rub off her two facial cocks with her graceful hands as her nipple penises prepared to ejaculate. She sped up fast enough and held back just long enough for all phalluses to fire at once.
The previously terrified girl's mind, now bathing in sheer ecstasy, collapsed on her apartment's sofa, her jiggling breasts and facial penises causing the remainder of the ejaculate to fly every which way in curved streams.
Lolling and panting, the girl then passed out, in a state of post-coital bliss.
