The queen let out a gasp and fell forward, her breasts pressing down against horse chest as her overly swollen clit brushed up against the nobbled rim of Fey's penis. She didn't stop moving however, her thighs pushing her forward, her slippery pussy sliding over the top and falling down in front of the length, the head pressing up against her crotch, parting her thighs.
"F-fuck, this feels- why am I more sensitive than I intended…? N-no matter, distractions shall not slow me."
The queen rocked her hips from side to side, each motion producing floods of her juices which spilt down the sides of Fey's barrel to wet the duvet.
Then she began to press herself back onto Fey. She had come prepared and Fey gasped as she felt the queen's pussy shift, her labia moving off its own accord, hidden muscles that should not exist squirming, hauling open her cunt, inching across the surface of Fey. The queen's clit moved and latched on too, curling and dragging itself across the surface, helping to open the queen, gaping her wider and wider. The sensation of the mimic's puss hungrily spreading itself to engulf her was a startling one, but that was as nothing compared to what happened next.
Fey shrieked as something from within touched at her urethra, a soft squirming thing that explored her shape, circling the hole. That sensation was joined by another and then another and another until nearly a dozen of the things were licking and fondling against the head.
"WHAT IS THAT?!"
The queen looked up at her and smiled, her tongue emerging from her lips, a very very long tongue and growing longer, really more like a tentacle than a tongue. She licked the air suggestively before pulling it back into her mouth.
Fey stared at the mimic queen in shock, her mouth hanging open, the truth of what the queen had said about experimentation that non-mimics weren't capable of now truly dawning on her.
"Hnff, such size, it is admittedly rare that a mimic would wield such a barbaric tool. AHH!"
She suddenly shuddered as her cunt yawned wide, splaying out, spreading wider and wider, accelerating until her inner lips were nearing the edge and a field of tentacle tongues slobbered over the tip of Fey's dick, making swirling motions as though blowing her, the effect in total was an almost overwhelming sensation and Fey's legs kicked involuntarily at the air.
With a lurch and a SCHL-POP! the queen suddenly rocked backwards, her cunt thirstily engulfing the massive head, her inner lips stretching out around it paper thin as her insides wrapped tight, the dozens of tentacle tongues pressed up vice tight against the centaur's length, barely able to move due to the sheer pressure, inching side to side as they still desperately tried to lick the surface.
The sensation was devastating and Fey cried out, her back arching, but that was a mild reaction compared to the queen. The queen's mouth yawned wide and she let out a shrill scream, her fingers digging into Fey's chest as her thighs wobbled like jelly. Her clit went rigid, swelling larger still as she squirted like a broken hose, clear fluid spraying down onto Fey's barrel so hard it misted, washing down over her barrel, making her sticky with the queen's juices.
"FUcCCKKAUUGHH!!"
The queen groaned long and loud as she came down from her shuddering orgasm, fingernails dragging lines down Fey's chest.
"Th-that-! THAT!" she breathed.
"M-more than you expected?" said Fey between heaving breaths, still struggling to deal with the insides of the queen constantly writhing over her dick.
"M-my mistake, I clearly made myself too sensitive… somehow…" she lowered her voice to a whisper and glanced down, "I am not quite sure how that happened…"
"So turn it off!"
The queen glared up at her then concentrated. After a moment she scowled.
"Why can I not…?"
"Is something wrong?"
"No! I have reduced my sensitivity, I h-have done so, there will be no further problems."
The queen steadied herself, determination rising, and then heaved herself backwards, plunging down the horse dick, sleeving her own body upon it, going much further in one push than she clearly expected as her eyes shot wide. Her belly tented out, her womb tattoo stretching tall as her body wrapped around Fey, moulding to her enormity. Of course, this only exposed more of the mimic queen's pussy tongues to Fey's length and the centaur whimpered as she simultaneously experienced both the sensation of the queen's unusual musculature and the feeling of being licked and slobbered on as though by dozens of girls. It was an intense experience to say the least.
"Hnnnnnn!!" The queen curled her body as she was stretched open, parted by Fey, a sprinkle of fluid raining onto Fey's fur, "G-gods that went in way too easy," she muttered as her body then eased.
"What was that?"
"Nothing centaur, I am but focusing on analysing your anatomy, studying you, hnff- in g-great detail."
That much was true, Fey could feel the mimic's tentacle tongues lovingly stroking and circling her flesh, tending to all of her.
"W-well maybe you need a closer look!"
"I... do-? AGGHHHH!"
The queen gasped as Fey bucked her hips and nearly a foot of dick shoved up into her causing her to shriek and squirt once more. Fey abruptly realised she might have made a mistake as the head of her cock slammed into the entrance to the queen's womb and it reacted, latching on, a great sucking motion coming from it as it made an airtight kiss on her urethra, in fact it felt very much like a mouth slurping at her.
"F-feels -so g-guuuuhdd," groaned the queen, her words starting to slur, as she finished spraying. Her clit had grown with her orgasm, swelling larger, its clitoral hoodfar too small to contain it, squeezed back by its sheer size. The dick bulge in her belly brushed against the freshly soaked through surface of Fey's barrel, the queen's skin becoming wet with her own juices.
