"Heck yeah I did..." Terry murmurs past the kiss. She strokes along the upper tentacle, then drops her hand to run her fingertips along the other giant tentacles between her legs. Small tremors ripple through them, making her moan softly. She follows the one in front to where it disappears into her body and massages around her wide-stretched lower lips with a sigh. Then she glances back over her shoulder at where her cheeks are divided by the other massive tentacle penetrating her rear end. "Oh wow..."
"All four bases in one go. Impressive," says Melanie quietly.
Is that a hint of envy that Harmony detects in her voice? The older women shakes her head and puts a palm to her face in disappointment. "All that training..." she murmurs regretfully under her breath.
"Terry, I..." Keith starts to say something.
"Sshhh," Terry puts her finger on the tip of the upper tentacle, even though it's not where he was speaking from. "It's going to be alright."
The monster quivers in her arms, drawing itself into a more compact ball. "I... it's all so overwhelming... I'm tired... I need... need..." his weird multiple voices go out of sync, echoing that last word and trailing off before he can finish his sentence.
"Come closer," Terry says softly, hugging that front tentacle to her chest. "I need you."
Harmony mentally scoffs at the younger girl's sappy words. It seems it's not the monster that's doing the hooking here. But then she sees Terry clench down and shudder in response to something that the monster does, her answer triggering some more strange behaviour.
With a surge, Terry's belly swells outwards briefly with Keith's instinctive thrust inside her. She throws her head back and moans throatily, the motion growing more insistent as her pleasure feeds into it. The tentacle in front plunges in and out, but the one in back just shoves in, pauses, then in again. It does this repeatedly, foot by foot of that immense tentacle making low squishing and squashing sounds as it penetrates even deeper into her anal depths.
Harmony can't help but stare in horrified fascination as more and more of that tentacle sinks completely inside the much smaller schoolgirl. Terry takes it like a champion, her body swaying from side to side as the monster has its way with her. Or is it the other way around?
"OoooOOHH!" Terry cries out as the entire length of that huge column quivers all along its length, jerking her back a little harder. The gigantic teeming ball of the monster's main mass draws underneath, still cuddling her, but as it runs out of tentacle it doesn't seem to be stopping there. "Oh my- oh KeeeEEEEITH!" Her cry turns into a delighted shriek as that massive ball wedges up against her butt.
"Holy shit..." whispers Melanie in awe.
The creature's body is massive. With all the tentacles bundled up around the girl, it looks like she's sitting on top of some strange nest several feet across. But the snake-like blue-green tentacles writhe with a single-minded intent, and before the spectators disbelieving eyes the creature seems to tuck itself into itself in a headache-inducing inversion, making itself smaller, more of its tentacles curling around and underneath and seemingly penetrating through its own body to extend upwards underneath Terry. There's a dull creaking sound as the girl's rump stretches even wider to accept more. Her head hangs back, her jaws working soundlessly, as her entire body goes tense under the otherworldly onslaught of pleasure. With her back arched fully, her belly sticks outwards, the dome of it gleaming dramatically in the low twilight.
The monster retracts even more, compressing itself down with tiny jerks and flexes, accompanied by loud, lewd, and very wet slurping sounds that carry disturbingly across the courtyard.
Harmony fights her growing sense of nausea at the sight of the poor girl's distended body. But the monster either can't or won't stop, and with a sudden *schl-PLOP* Terry drops down almost all the way to the ground with a loud gasp of surprise, her butt wobbling drastically as it flexes around the massive intrusion. The teacher runs to Terry's side as the girl shudders tremendously, her eyes rolling back, and makes it in time to keep the girl from falling backwards onto the hard pavement. She gets a good close look as the last several thick tentacles slurp backwards, drawing themselves after the main mass of the creature inside the girl's body until they vanish completely between her cheeks.
Terry's butt flexes back to more normal dimensions in moments as her anus finally squeezes shut. Her body tenses one last time as she lets out a short moan, then goes completely limp in Harmony's arms. The incredible roundness of her belly writhes fitfully with soft bulges, gurgles loudly, then begins to shrink too. Bit by bit, her gut dwindles in size until it goes completely flat.
"Oh for the... Terry!" Harmony looks down with concern at the girl's blissfully closed eyes.
Terry slowly stirs at the sound, opening her eyes to gaze up at her teacher with a look of total satisfaction. "Oh, hello, Ms. Gallerston," she murmurs, then closes her eyes again.
