Attaches it to Stacy's pussy

Stacy's body laughed silently as it held the slimy thing just in front of her breasts, its tiny mouth gasping as it stretched to reach her nipples. At the last second, her arms pulled it away and Stacy felt her relief turn sour as she felt her body kneel on the floor, leaning back against one wall so that she had a clear view of the worm being lowered between her legs.

Stacy's horror at the thought of the thing crawling into her pussy rocketed when it suddenly shot down and latched onto her clit, the ring of tiny feelers around its mouth burrowing into the flesh surrounding it. The sudden stimulation sent her body into a blind fit, arching her back as she shuddered violently, but her body kept her eyes fixated on the worm as her hands released it. It landed against her belly with a splat and sat there, suckling on her clit like a baby.

As the agony of being penetrated so invasively faded, Stacy became aware of a steady, rushing sensation between her legs that felt disturbingly familiar. Her suspicions were confirmed as the creature began to slowly swell, its body becoming bloated with the blood it had drained from Stacy's clit.

Oh God, not again...

She felt herself becoming light headed as drop by drop, the thing drained Stacy's body of her life's blood. She was on the verge of passing out when the suction stopped, leaving her dizzy and confused.

A sudden contraction send a rush of blood back into her body, her mind clearing as the thing on her abdomen noticeably shrank, but as it did so, Stacy noticed the textures of its skin changing. Much as the grey worm that had penetrated her mouth had stolen the appearance of her tongue, the dark red thing attached to her clit was turning into something she recognised all too well. She'd seen one very recently.

Between Alex's legs.

With each rush of blood, the worm's surface became paler, matching that of Stacy's own skin except for the head which remained a deep crimson. Eventually it deflated completely, shrinking down against her stomach like an empty balloon.

Stacy didn't know what she could possibly hope for, other than that she might wake and find that this had never happened, or at least that soon she might lose her mind completely. Stacy's body stood up, her joints sore from being in such an awkward position for so long, and looked into the mirror, her new addition dangling limp between her thighs.

As she stared at her newly attached cock, her face smiled and licked its lips slowly. Stacy could sense what it was thinking about, could feel the beginnings of arousal tickling her insides and a rush of blood begin to move between her legs. In time with the beating of her heart, Stacy's cock began to slowly harden, raising itself little by little as the involuntary desire flowed into it.

It felt... cold... lonely. Stacy could almost feel it cry out for the embrace of something warm and moist.

And with that, her body spun around and sat down on the toilet seat, the head of her now painfully hard dick twitching inches away from her face. She knew what she was going to do, what her penis desperately wanted her to do, but she still fought uselessly as her body lowered its head, her tongue reaching out and swallowing the head with its open tip.

Stacy felt the hot sensation envelop her cock, felt the glorious warmth wash over her penis in a lover's embrace, and lost consciousness.

Stacy opened her eyes in a world of red and white. All around her, a landscape of softly pulsating flesh stretched into infinity while the "sky" was pure and featureless. The "ground" was soft and slightly damp, but firm enough to stand on.

Stacy felt unbalanced as she rose, as though her body wasn't quite hers, but noticed that she didn't have a cock and that when she stuck her tongue out, it only went as far as it normally used to. Even though she felt unaccountably uncomfortable in her own body, it was her body. Her normal, human body.

Where...?

A sudden presence behind her made Stacy whirl around and **** back a scream. In front of her stood herself. Two of herself. One of them with a tongue that dangled down to her breasts and the other with a penis so hard that it trembled.

Stacy paused for less than a second before turning to run.

A mouth suddenly opened in the flesh where her foot landed, sucking her down to the knee and pulling her off balance. The hand that she flung out to catch her fall was also captured, and soon Stacy found herself trapped on all fours as the figures behind her languidly made their way over.

Her doppelgängers remained mute as they approached, instead giving her a predatory smile. The one whose tongue left trails of drool across her tits kissed her deeply, her alien tongue wrestling with Stacy's own human one. Stacy squirmed, the joy of finally being able to fight back tainted by how helpless she still remained.

The fake broke away, licking Stacy's face playfully before crawling around her arms and beneath her body. Stacy tried to look down at the sensation of something warm running against her breasts, but her chin was jerked up by the other fake, its rigid cock pressed hard against her face. Stacy could feel every heartbeat, every surge of warm blood that flowed through it and gritted her teeth.

But she was unprepared for the sudden warmth of penetration as a tongue **** itself into her pussy. She moaned instinctively, unable to stop herself before her fake shoved its cock into her mouth. Her wild attempts to wrench her head away were useless and she had somehow lost the ability to bite down.

The feeling of being penetrated below had changed to a rhythmic sucking as the tongue writhed around her clit, licking and teasing and forcing her body to respond even as her mouth was assaulted. The doppelgänger fucking her face suddenly tensed, an expression of ecstasy passing across its features as something warm poured into Stacy's mouth.

She had prepared herself for the chocking, foul taste of semen and was shocked into stillness.

It's... sweet?

Without thinking, her body swallowed a mouthful of the stuff to avoid **** and Stacy couldn't resist swallowing a second. It was the best thing she'd ever tasted, its heavenly flavour matched only by its smooth, creamy texture. She leant forwards against the cock in her mouth, her tongue now eager for more as it wrapped itself around the shaft.

Around and around and...

Stacy pulled back in alarm, her tongue refusing to relinquish its coiled grip on her mirror image's penis. She stared in horror at its snakelike length only to shudder as she felt something far too long to be her clit being sucked beneath her. Her tongue slowly withdrew between her lips as she froze, paralysed by the sensation of having her alien appendage drowning in a sea of warmth. A steady, juicy, squishing sound came from beneath her legs and again, Stacy felt the cock in front of her pressed into her unresisting mouth.

She wanted it - needed it - and this time, Stacy's tongue was her own to command. She felt the muscles within twitch, opening the tip like another pair of lips which attached themselves to the head of her twin sister's cock and thrust forwards, engulfing its entire length well beyond Stacy's own mouth.

She watched, mystified as her tongue-pussy fucked the length of the penis in front of her while the steady pumping below mirrored her own vision, the sensation giving the bizarre illusion that she was going down on herself. Even the insides of her tongue could taste the sweet juices that leaked from the tip, and as her fake's hips began to shudder in anticipation, Stacy felt her own orgasm beginning to rise.

The pace her bodies set was relentless, and as the pressure reached unbearable levels, she felt her own cock release in the same moment as the one buried in her tongue, its explosive twitching mirrored beat for beat with her own as the warmth rushed down her throat and out from her loins.

As the euphoria began to overwhelm her, an alien thought entered her mind from the encroaching darkness.

You will surrender yourself. There is no other outcome.

Stacy awoke feeling bewildered and exhausted.

She looked around blearily, realising that she was sitting on something in a place. She frowned.

The thing was a... toilet. And the place was... bath room.

A slimy, flapping sensation at her chest made her look down. Something long and pink had attached itself to one of her breasts and was suckling at her with enthusiasm, its tail whipping back and forth, coating her in its slime. She realised vaguely that she must have run dry and gently placed it against her other nipple before wondering why.

You will feed the young one.

Stacy blinked. The thought wasn't hers, but it had come from her own head.

With great effort, she remembered what had happened, but it was odd, as though she remembered seeing it in a film happening to someone else. She must have impregnated her own tongue, giving birth to this new worm, covered in ridges with a strange bulb at its tail.

She knew she should be feeling something, and tried to recall what it was. A fleeting sensation passed her mind, an echo of emotion that only barely brought a tear to her eye. She felt a twitch in her head snuff out the sensation, and knew.

They had taken part of her mind from her. They had taken it for themselves.

Correct.

A cold, hollow sensation that might once have been horror, despair or mourning opened up within Stacy, but was again blown away as the things in her mind wiped it out. Instead, she felt her body twitch back into life, standing in the mirror once more with the newborn at her breast, her expression of glee masking the empty hopelessness she had become inside.
