Asuka belched wetly then winced as her distended belly groaned in discomfort. She'd thought being shoved bodily into Shinji's monstrous cock was nightmare enough, but that was before she'd fallen into one of his testicles.

There was more room here, barely, than when she'd been squashed inside his cock, but it came at a steep price. Shinji had spent most of the time since she'd popped through the valve into her scrotal prison fucking - she had no way of telling with whom - with wild abandon, and his balls slapped heavily against assorted asses, chins, and other body parts, and Asuka slapped with them. If her prison had been made of brick and mortar, rather than flesh and blood, she would long since have been broken beyond recognition. Instead, she was bruised and sore, bounced around so much - and so often in motion - that she could have no more identified which way was up than she could have given birth to a horse.

And even that wasn't the worst of it. Asuka had always known, in an offhand, learned it in Sex-Ed sort of way, that a man's balls were where is cum was produced. What she hadn't known, until today that is, was just how fast some men, i.e. Shinji, could produce a full load. Maybe it was all the changes that had been happening to all of them, or maybe Shinji had always been quick to reload, she didn't know or care, but the fact remained that her little round cell filled with sticky white goo at a dangerously fast rate. So fast, in fact, that she was dreading what would happen when, inevitably, Shinji took an extended break. Even his short breaks while switching women, or maybe just waiting for Misato to recover, had been enough to induce her present predicament.

In order to keep from drowning in cum, Asuka had been forced to take in the excess whenever Shinji wasn't blowing his load. She'd been gulping it down by the mouthful every time the world stilled enough to indicate her captor wasn't going to spurt soon enough to serve the purpose of preventing her from drowning in the stuff. She'd already swallowed gallons of his hot spunk, and her stomach was grumbling unhappily at the strain, stretched to such a girth that it was hanging down below her waist, forcing her legs to splay apart.

Fortunately, or unfortunately depending on her mood at any given moment, Shinji's cum was more than willing to make use of her instead of whoever he happened to be fucking. Any time she relaxed even the slightest bit, hot cum flooded up her pussy into her womb, as well as through her ass and into her bowels, partially accounting for how she had filled up so quickly. She was also, naturally enough, plastered head to toe with cum that she hadn't managed to get into her belly; her hair had practically turned white there was so much in it.

There was one thing going for her: the last time Shinji had climaxed had been right after she had managed to almost empty the testicle she occupied, and she'd relocated the valve through which she'd entered and which controlled egress from same. She hadn't been fast enough to escape then, but she had managed to get her left hand wedged in, up to the wrist. The next time Shinji ejaculated, she intended to ride the wave. She could only hope no one was giving him a blowjob at the time.

...

After what felt like hours, as Asuka nervously watched her cell begin to fill once more with cum, she felt Shinji shift position and the telltale jarring began that meant he was once again vigorously pounding someone. After more agonizing waiting, made more so because she was being flung about while her arm was pinned in place, she felt him tense up and the valve began to loosen. She quickly pulled herself as close as possible as it opened and...

...

Shinji had more or less forgotten his little occupant since she had been shoved down his cock by Misato, mostly because he'd been having mind-numbing sex almost nonstop ever since. He did, however, notice when the small knot formed at the base of his cock and slowly began forcing its way up to the tip. He didn't really care - it felt exquisite - and the only part of his mind to connect that knot to Asuka was not actively engaged in his present activity. So, even if he hadn't wanted to release her yet, he never paused as the powerful orgasm pent up behind her finally erupted when she reached his tip and blasted her deep into the womb of -
