All of It

For all of its intimidating length, Porkum's cock was not as rigid as a baseball bat. It compressed and squeezed like a rubbery sponge. So too, the Invisible Woman's asshole, while formerly virgin, was at the peak of unaugmented human elasticity and strength. As the villain fed his cock into her gaping hole, she took it like an adult porn star who had trained her ass for years.

Just to be on the safe side, Porkum went slow. His salliva was a better lube than anything on the market, but even so Sue Storm whimpered as he fed inch after inch of his massive pink worm into her gaping ass. Sue felt it slide deeper into her guts. Felt her anal ring stretch little by little, as the cock thickened. Her head swam, awash in Porkum's pheromones, but all she could focus on was her ass, the slow, massive insertion that was stretching her poor hole to its limits and rearranging her internal biology.

Literally. Porkum's precum sloshed through Sue Storm's intestines, and the specialized sperm in his pre-cum attacked cells, released compounds that muted pain, increased elasticity, and eased the passage as two feet of mutant dick pushed forward into the heroine's digestive track. The Invisible Woman's abdomen bulged as the semi-rigid cock stretched her out...and then it happened.

Porkum's massive balls slapped against her pussy. The impact of those hot nuts against her snatch sent a spasm through Sue Storm's body. Her whole form quivered with sudden, unexpected pleasure, and she squired a little, her heart juices anointing those immense balls like a bottle of champagne christening a new ship. Porkum grunted in satisfaction as the MILF's ass stretched around the base of his cock. Sue herself was beyond rational thought, impaled, her asshole dilated more than her cervix had been when she had given birth to Franklin.

With barely a grunt, Porkum lifted her up, still impaled on his cock. Her spine curved along his great gut, and he looped her arms around the back of his neck.

The Doombots moved in. Sue was barely conscious as they connected her to a kind of harness, strapping her to Porkum's body, unable to move her arms and legs. Unable to do anything but lie there, completely impaled on Porkum's dick, in full view of anyone. With a chuckle, Porkum reached forward and played with the Invisible Woman's breasts. She moaned, her blonde head lolling, the sickly yellow light of the defraudium crystal at Porkum's throat bathing her in its disabling glow.

"Right then," he said. "Time to go for a walk."
