Through her belly

Some time later, Aurora stirred. She wasn't sure how long she had lain there in a haze, but the quality of the light hadn't changed. There was no way to mark the passage of time, no day/night cycle she could notice. The room she lay in was lit seemingly from all around with gentle bio-luminescence, which pulsed like the beating of a giant, slow heart. Still groggy, she looked around for a door... an exit... some feature, but the walls were featureless and smooth, with a rough organic texture. The resinous fluid that had bonded her to the wall had dissipated or something, leaving her lying on the floor. She rolled over, her memory starting to come back...

and nearly vomited at the sight of her body.

Aurora had always been quietly proud of her breasts-- military-issue flak armor did little to emphasize them, but she had always been well-endowed and more than once had caught other marines trying to catch a quick glimpse in the shower or when they thought she wasn't looking. Her skin was smooth and clear, and she exercised regularly and watched her diet to avoid unsightly stretch marks. Now, though, her breasts were grotesquely exaggerated. Each was the size of a basketball, orbs of soft flesh that jiggled and gyrated unnaturally. What's more, there were four-- a second set of equally enormous tits hung below the first, pressing uncomfortably up on them from below.

The second set of breasts were sandwiched between what she was already thinking of as her original tits and a bloated, rounded stomach. It had the look of pregnancy, but exaggerated far beyond any normal human proportion. She found she could roll over, but standing up was out of the question. Her legs felt weak and rubbery, but even at her full strength she doubted she'd be able to left her massive stomach. It had to be at least a meter in diameter. As she watched, something rippled inside her womb, sending a wave of nausea through her-- mixed with an electric feeling of pleasurable tension.

She hazarded a feel of her breasts and was revolted by their soft pliability-- her finger sank three inches deep into what felt like jelly. She yanked it out as if stung, and the flesh placidly returned to its former shape. Even a gentle touch, though, had been enough to awaken a fire in all four of her breasts. Her nipples glistened like dark coals, each leaking a steady stream of fluid that coated her breasts. They ached and itched for release.

Moaning softly, Aurora reached a hand down to her top right breast and gripped her nipple. Normally she would only be able to lightly pinch her nipples with her fingertips on the rare occasion she had the time and privacy to masturbate, but with the increased size and altered texture of her breasts she was able to grip the nipple tightly in her fist and still see the very tip peek out between her thumb and forefinger. She had only meant to caress herself lightly, but as soon as she touched herself a wave of pleasure bloomed outward from her areola and she squeezed as hard as she could. More of the thick fluid gushed from her nipple, oozing over her hand. It smelled faintly like old incense. She tried to reach her pussy with her other hand, but her massively oversized stomach got in the way. Instead, obeying an instinct she didn't even know she had, her questing fingers found a gap above her navel, ringed by tiny teeth, and opening into a second vagina. She didn't hesitate to question this, but began rubbing around the rim, looking for some kind of clit analogue. Brushing her fingers against the bottom of the opening sent an electric tingling up her spine, so she focused her efforts there while kneading her breast with her other hand. Between her legs, she felt her "real" pussy spasming. She had had orgasms before, but nothing like this. The pleasure seemed to be suffusing her entire body, coming from everywhere at once.

Breathing more quickly, she felt something twitching deep inside her. One of her hands continued milking her engorged nipple, squeezing as hard as she could and releasing in a rhythmic pattern. The other crept up to one of her lower tits and fastened on, her fingers plunging deeply into her spongy, yielding flesh. The flow of thick, slimy fluid from all four of her nipples intensified. She opened her mouth wide and squeezed a jet of it onto her face, spattering her hair with goo. Most of it went down her throat, and she swallowed enthusiastically. It was warm and tasted sweet, like honey. The twitching intensified, as if whatever was moving inside her had tasted it as well. She felt another orgasm overtaking her and she bucked and writhed wildly, pinned under her bloated stomach as she was. Her pussy gushed-- she had never been a squirter before, but it seemed that whatever modifications the Pisceans had made to her body extended that far at least. As she felt the fluid welling up inside her, waiting for release, she felt whatever was inside her stomach move as well. The pleasure abruptly turned to agony as she felt herself stretched from the inside out.

Aurora had never had a child, but she recognized the pain of childbirth when she felt it. She through back her head and howled, her fists beating futilely against the soft floor of the room. Whatever was inside her wasn't a passive baby-- it was pushing, trying to get out. She thought she would split open. Her "baby" was huge-- at least the size of an adolescent human. She could feel her insides deforming around it as it quested blindly for freedom. Her stomach-pussy felt like it was going to rip in half. Another spasm of pain wracked her-- a contraction-- and she howled until she was hoarse. Nobody came. No alien midwife stepped into the room to help her. She lay panting as the pain receded, until another contraction hit-- the worst yet. She thought she might black out from the pain. Something was forcing its way out of her. The first thing to appear was a rough ovoid about the size of a football. As its widest part cleared her stomach-pussy lips she could swear she felt something tear, but it didn't notice or didn't care. She pushed hard with muscles she hadn't had until her abduction, trying to **** her baby out before it killed her.

The ovoid turned out to be a bullet-shaped head. The thing's neck was slender, giving her some respite, but the body that followed was even thicker. Grotesquely, the feeling of the thing's ribbed chest against her second clit sent waves of pleasure through her, and her four tits erupted in a thick milky spray. This display appeared to encourage the thing, which heaved more of itself out of its mother. Following the sinous body was an amorphous mass of tentacles-- these at least were soft and passed easily out of her. When the last of them cleared her womb, a flood of greenish slime poured out of her. She thought light-headedly that that must explain her immense stomach-- there must have been four gallons of the stuff pouring out. The flow slowed to a trickle and Aurora, exhausted, slumped onto her side and began to cry.
