Chapter 17: Monstrous Pleasure
Brenda’s scream echoed off the bedroom walls, a raw, ragged sound torn from the depths of her being. Her body arched, rigid as a bowstring, every muscle locked in a spasm of overwhelming sensation. Her cunt clenched. Hard. Brutally hard. A vise grip of slick, desperate muscle spasming around the impossible girth splitting her open. Wetness flooded between her thighs, hot and sudden, soaking Harold’s groin and the bunched comforter beneath him.
"Oh FUCK! OH GOD, FUCK ME! YES! MORE!" she shrieked, the words dissolving into a guttural moan as the violent clenching triggered another wave of agonizing pleasure. Her hips jerked erratically, uncontrollably, grinding the massive, pulsing shaft deeper, impaling herself on the monstrous thing tearing her apart.
Harold could only watch, terror and a dark, unwanted thrill warring within him. Her pussy, stretched obscenely wide around the deep purple head and swollen shaft of his secondary cock, glistened under the dim lamplight, lips pulled taut and trembling. The sheer size was unreal. It looked like she was trying to swallow a fist. A thick vein throbbed visibly along its length, pulsing in time with the deep, terrifying thrum Harold felt radiating from its core. Growth. It hadn't stopped. Inside her convulsing depths, the flesh pulsed again, thickening infinitesimally but undeniably against the crushing resistance of her body.
"Bren... stop... please, you have to..." Harold gasped, his voice choked. He tried to lift his hips, to dislodge her, to pull the monstrous thing out before it did unthinkable damage. But her weight pinned him, and the brutal grip of her orgasm held him locked inside her molten depths.
"NO!" she snarled, her eyes wide, pupils blown dark with lust and pain. Sweat slicked her red hair to her forehead. She slammed herself down again with a wet, meaty smack, forcing every inch of the pulsing thickness back into her impossibly stretched passage. "FUCK ME! RIDE IT! RIDE THE FUCKING MONSTER! STRETCH ME WIDE, HAL! MAKE ME TAKE IT ALL!"
Her hand abandoned his chest, flying down to where they were joined. Her fingers scrabbled at the swollen flesh of her outer lips, stretched taut around the base of the secondary cock. She pressed hard, frantically rubbing her clit in rough, frantic circles. "Feel it! Feel how fucking big you are inside me! Oh god, it's so deep... so fucking thick... I can feel it moving..." Her words dissolved into another choked scream as the secondary cock pulsed again. A distinct, sickening expansion under her probing fingers.
Harold felt it too. The deep internal throb. The terrifying pressure intensifying, the flesh swelling against the confines of her body. The heat was fierce, radiating outwards, making his own skin prickle. He could feel the drag of her inner walls, impossibly tight even stretched to breaking, milking the throbbing girth. It was excruciating pleasure fused with bone-deep horror.
"Ahhh! Christ! Bren, listen!" He managed to grab her hips, his fingers digging into the flesh of her ass, trying desperately to still her frantic bouncing. Her skin was slick with sweat, burning hot. "It's... it's still growing! I can feel it! You have to get off!"
But Brenda was beyond reason. Lost in the maelstrom of sensation. The pain was a white-hot brand igniting every nerve ending. The stretching was unbearable, yet the friction, the sheer fullness, was driving her towards another precipice. "Fuck your warnings!" she spat, her voice hoarse. "Fuck your wife! Give it to me! GIVE ME THAT MONSTER COCK!" She wrenched her hips free of his grasp and rode him with renewed savagery. Downward thrusts that were less about movement and more about brutal impact, pounding herself onto the expanding shaft, forcing it deeper than should have been physically possible.
Each brutal descent sent shockwaves through Harold. The monstrous secondary cock filled his awareness, a pulsing, demanding entity consuming sensation. But there, trapped against the heated curve of Brenda’s ass, lay his neglected primary cock. It stood rigid, thick and veined, weeping a steady stream of pre-cum onto the sheets. It felt almost alien now, dwarfed, insignificant beside the obscene bulk of its twin. A familiar ache built at its base, an ache utterly drowned out by the terrifying symphony emanating from the other.
As Brenda slammed down again, her cunt clenching in another agonizing spasm around the invading girth, the friction against his trapped primary cock became too much. The base rubbed roughly against the sweat-slick skin of her ass cheek with her violent motion. The neglected pressure, the sheer overwhelming sensory overload, triggered it.
With a choked gasp that was half-sob, Harold felt it. His primary cock twitched violently against her ass. A thick, pearly rope of cum spurted out, landing with a soft plop on the floral comforter beside her thigh. Then another. And another. Short, weak bursts, utterly devoid of the powerful release it usually delivered.
Brenda barely registered it. Her focus was solely on the searing stretch inside her. "Yes! Fucking yes!" she moaned, mistaking his choked gasp for shared ecstasy. Her grinding intensified, her body demanding more from the impossible flesh filling her. "Harder! Make it hurt! Make it split me! Oh god, Hal... it’s... it’s getting hotter... bigger... I can feel it... fuck... I can feel it swelling..." Her voice rose, tinged with a new edge, not just lust, but dawning, breathless panic mingled with the relentless drive towards oblivion. The wet sounds of her frantic riding filled the room, punctuated by Harold’s ragged breaths and the helpless, weak spurting of his abandoned cock against her skin. The monstrous secondary cock pulsed again, deep within her straining depths, its relentless growth unchecked.
