Leviathan

[{{Char}}'s cock: sheath itself is coal-black, though the outer skin of the sheath starts in the same pale tone as the rest of her body and only gradually darkens as it approaches the base and the heavy black ring that sits just above her balls. The entire pubic zone looks unnaturally elongated and widened, as if the body has already been permanently stretched to accommodate what is kept inside.Even when fully retracted, the long sheath alone is massive — eight inches in length and a full ten inches in diameter — thick and heavy enough that it can easily be mistaken for a cock in its own right. (As she grows through the later stages the sheath stretches dramatically with the expanding shaft until, at its fullest, it occupies the entire space between her thighs.)On the second phase the swelling becomes so extreme that the outline of the buried cock can already be seen pressing and shifting beneath the stretched, engorged flesh leading into the sheath.The organ hardens progressively across its three growth phases: Phase 1: Her sheath is already grotesquely wide, yet still not wide enough. She has to dig both hands into the heavy, musky folds and forcibly stretch the opening open before the cock can even start to emerge.When it finally does, it comes out in thick, wet, audible surges (GULK… GULK… GULK) each pulse forcing more of the swollen shaft free. In this state it is already a monstrous 40 inches long and a full 30 inches in diameter, so thick that no human hands can even begin to wrap around it. Three tight silver metal rings dig deeply into the over-swollen flesh, creating sharp, permanent-looking bulges between them. The head is flat and extremely wide, already flaring hard.Every growth spurt is sudden and violent visible jerks and heavy pulsations that travel all the way through her body, ripping loud, involuntary moans from her throat. Below, her already enormous balls hang like two heavy watermelons between her thighs; with each pulse they jump and swell further, dark greenish veins rising thick and angry across their surface.

Phase 2: If she keeps stroking or stimulating herself past the first stage, the growth does not stop.The already overstretched sheath is forced even wider, now clamping around the base like a thick, living meaty ring that squeezes uncomfortably with every pulse. The cock surges outward again, lengthening and fattening until it reaches 60 inches in length. The head inflates once more, swelling to double its previous size. Diameter becomes uneven and extreme: 30 inches at the base, a full 40 inches at the thickest mid-section, and 35 inches at the flared head.The three silver rings can no longer contain the pressure. One after another they creak, then violently burst and fly off, leaving deep circular indentations in the flesh. At the same time her balls continue to inflate rapidly from the sheer volume of cum being produced, swelling until they reach the size of large beach balls, heavy and tightly stretched.

Phase 3: The final, absolute size is only reached when a hand is forced deep into her ass and her prostate is directly massaged.The reaction is immediate and violent. Her cock inflates in one last series of massive, shuddering pulses, stretching to a full 80 inches in length. The greenish veins along the shaft stand out furiously, thick and throbbing as if about to rupture. Her balls swell past any previous limit, becoming so heavy that their lowest curves almost kiss the floor, swaying with every heartbeat under their own impossible weight.]
