The Fall of Heaven

The Swamp Witch has sent a army of demons to invade heaven and conquer it.

The angels of Heaven had put up fierce resistance, but as their realm was slowly corrupted by the Swamp Witch's magic, their resistance slowed ebbed. The Swamp Witch unleashed a powerful magic spell that corrupted the angel’s holy power. The angels are unable to properly use their holy magic as it was being corrupted and replaced by dark magic, which make things easier for the demon as they had defeated most of the angels and **** them as their sex toys.

Nanael knew that the invasion of Heaven was reaching its climax. All around her, the once clear sky was now dark gray and emitting a dense and oppressive atmosphere. The formerly pristine white clouds and clear streams were darkened like thunderclouds. There was even lightning that flashed in the distance. One by one every angels that was captured by demons are beings **** turning into sex ****. The Swamp Witch had almost completely conquered the realm, if not totally dominated it already.

Nansen: "I fucking knew this would happen!"

She whimpered. She didn't like abandoning her fellow angels (unless it served to gain her an opening to escape), but she knew that fighting the demons was a lost cause. With all the loud moans and screams going on, she also had a feeling that her best friend Hachiel was among those being turned into winged sex toys.

Nanael would've already high tailed it out of Heaven and went down to Earth, but only the Head Angel had the power to send angels to the human world without danger. There were other ways, but Nanael was nowhere near any portals or pitfalls she could take, and thus she was scrambling around like a headless chicken looking around for a way out.

The flapping of large wings alerted Nanael to the coming of demons and she looked up to see two shadows coming down on her.

Nanael: "No, no, no!"

She tried to weave through the clouds and temples to lose them, but two sex hungry demons are hard to escape. Though she was a fast flyer, they were just a bit faster, and when the two demons split up to corner her, she knew she wasn't getting out of this unfucked. They blocked off her two escape routes and then **** her into a prayer temple, where she couldn't find room to fly away.

Now Nanael was pressed against the wall, trembling as the two demon marched up to her. She looked down and gulped at the sight of their erect cocks pointing towards her, as if sensing the presence of a fertile female close by.

Nanael: "W-Wait!"

Nanael pleaded, hoping that they'd at least pause to listen.

Nanael: "L-Let me do it! I'll fuck both of you at once, just don't **** me!"

It was a desperation move, not wanting to be fucked into lustful insanity like the other angels, but knowing that any further attempts to escape was ultimately futile. At the very least, she could do this on her own terms and maybe even get off lightly after it. Not like the other angels would call her out on her bullshit.

And that was what led her to kneeling between the two demons on all fours, with one of their cocks in her mouth, while the second one groped her soft ass, slapping her behind while groping her soft flesh afterwards. As she bobbed her head up and down its cock, the demon behind her flipped up her skirt and tore off her panties, ripping them right off her bubble butt to fully expose her.

The Demon she was sucking off wasn't too pleased with her getting distracted, and it reached out to grab her by the wrist, guiding her free hand under its cock, to its balls. She began to massage and knead its nutsack, even as her eyes started to water from just how deeper she was taking its cock. From how deep the demon was MAKING her take its cock.

She choked and gurgled on its thick, meaty member, the tip of which continued to slide deeper and deeper into her esophagus. Nanael was so busy trying not to **** from the cock stuffed down her gullet, she was completely taken by surprise by the second Grigori, which had pressed its cock against her slit half a second before the rest of its demonic shaft slammed home into her dripping wet, but wholly unexpected cunt.

Nanael's eyes went wide and she squealed all over the youma's cock as the one in her cunt immediately started on a rather brutal and rough pace. It fucked her without consideration for herself, but the pain she felt was minimal. The pheromones that were absorbed into her body dulled the pain of being fucked so roughly, and before long the girl was moaning around the demon’s cock even as her inner walls clenched along the pistoning member. The winged demon fucked her from behind, laying a fresh slap against her bouncing, jiggling ass every once in a while, while the one in her mouth **** her further and further down its equally impressive shaft, until she can't even keep her had on the base of its member anymore.

There's no mercy in it, as her free hand pressed against the stone wall for support and her lips finally reached the base of the Grigori's cock, the entire length buried in her tight, convulsing throat. Her pouty lips pressed into her other hand, which is still massaging its ball sack at this point. She slobbered all over her fingers and the demon’s nuts, even as her eyes threatened to roll back into her head.

And yet, despite their rough treatment of her, the pleasure is overwhelming. There's no discomfort, no pain. Not anymore. Demonic energy flowed into her body, perverting her mind, mutating her into a creature who lived only to get whatever cock she could find. Nanael is beginning to see this, even as she reached her peak and hit her first orgasm.

The way they were fucking her with such wild abandon, Nanael couldn't imagine a regular human woman surviving such a thing, even as she cried out around the cock in her throat, her eyes going crossed for a moment from the pleasure that washed over her. Her inner walls tightened and squeezed rhythmically around the demon’s length, and it groaned by kept fucking her all the same, burying its entire length in her cunt with each and every thrust.

Nanael's eyes rolled up in her head on her next climax. She moaned around the cock, her tongue slathering around its length. With a grunt, the demon fucking her mouth tightened its grip on her hair for a moment, and then began to cum. She wasn't really ready for it, and with its cock buried in her throat, she made quite a mess as its seed came back up and exploded out of her nostrils and the sides of her mouth. As the demon released her, however, letting her slowly pull her throat off its cock, another hand grabbed her to drag her up a bit faster.

The azure haired angel was left moaning profusely into open air, her eyes glazed over with pleasure and her ruined face covered in cum as the demon dragged her head and **** her back to arch. Her tits bounced and jiggled, giving the demon in front of her a front row seat to her fucked silly expression as she came again and again on demon cock, until finally, her insides milked the demon of its own release, its seed filling her womb.

As it slid out of her, and Nanael fell forward, landing onto the ground, squishing her breasts underneath her. She twitched and convulsed on the ground, her ass stuck in the air, even as the demon’s seed flowed out of her. The two demons stood over her, cocks still erect as the young angel started emitting dark energy from her body.

There was one little thing that the Swamp Witch added to the demon before invading Heaven. She made their seed incredibly corruptive and addicting, more so than a regular demon’s. For angels, it corrupted their holy energy, the very fiber of their being, and turned them into something little more than a demon in nature.

Nanael's wings were the first to turn, her bright white feathers slowly darkening until they were pitch black. This spread to her clothes to, turning from white to black and oozing wisps of black energy. Nanael felt her body become rejuvenated and energized. She got on her knees, moaning and rubbing her cum stuffed pussy as dark magic flowed through her veins. It felt so good, so wonderful. It felt so…erotic.

When her conversion ended, Nanael's dress and wings had turned black, her eyes a deep violet that conveyed the horniness and sinful cravings she was feeling at the moment. Meanwhile, the two demons who fucked her are both looking at her expectantly, their cocks hard and ready to go.

Nanael: "I'm ready for round two if you two are."

Nanael smirked and leaned over to take the cock that had jazzed in her womb in her mouth this time, while she jutted her ass out in the other demon’s direction so the creature can have its way with her.

This is her new life now. This is her reward for being so accepting and submissive to her new masters.
