Hiding Her Cunt-Stretching Is Harder Than She Thought

Sue Storm had given birth to two children. Natural births, not Caesarians. Her pussy was not the demure, tight little slit it had been when she was a teenager. Over the years, she had noted the changes to her body—and taken a certain amount of pride in the stretch marks, the slight darkening of her labia, as marks of womanhood.

Two weeks of using Porkum's toy whenever she could, however, had repercussions.

Reed, Ben, and Johnny had returned empty-handed from their interdimensional trip. Franklin and Valeria had returned. The family was back together once again, the Fantastic Four reunited, and Sue's leg healed enough that she could participate in missions. Porkum's immense dildo was tucked away in the back of Sue Storm's closet, available whenever she had a few minutes for some big-dicked fun time, the pheromones embedded in the material maintaining the biochemical control that the mutant pig-man had subjected Sue to.

The toy, she could hide. Her sessions with the toy, even the videos she had sent to Porkum showing how she could take almost two-thirds of the immense length, were easy enough for the Invisible Woman to conceal. But what Sue wasn't prepared for was the effects of the cunt-stretching with the mutant dildo.

"Jesus fucking Christ, Sue," the Invisible Woman muttered to herself.

Her labia wasn't just puffy, it was protuberant. The lips had thickened and hung nearly three inches down her thighs. Normal panties were swallowed by the hungry, often wet and dripping maw of her cunny, and during the day Sue felt miserably empty, her thighs rubbing her engorged cunt constantly.

In her costume, it formed the biggest cameltoe imaginable. Sue had swiftly had to shift her costume to include a skirt, just to disguise the protuberant pussy. And now that skirt was getting tight. A quick check with the measuring tape confirmed it: Sue's hips were wider, and getting wider. Her buttocks were putting on muscle and fat. All of which required a careful rethink of her wardrobe, both civilian and superheroine.

Reed Richards didn't seem to mind the slowly expanding hips and ass. But that brought with it other problems. There was no way Sue could take Reed without him noticing the gaping fuckhole that had once been his wife's tight slit. Sue fretted about that. One loose fuck would ruin weeks of secretive masturbation.

And Reed and Sue's anniversary was coming up.

So when, on that night when Reed abandoned his lab for a candlelit dinner, cracked open the champagne, and strewed their bed with rose petals, Sue had a plan in place.

"You know, darling," Sue said as she stepped out of the bathroom in just her lingerie. The room was lit only by candles. "I'd like to try something different, tonight."

The unstable molecule panties carefully covered Sue's pussy, but left a cut-out over her freshly cleaned asshole.

Reed went slow. Used lots of lube. He was gentle as he pressed the rubbery glans against her pert pucker...and Sue, unable to contain her excitement, had uttered one word:

"Bigger."

By the end of the night, his python was nearly the size of Porkum's inhuman prick. Sue Storm bit the pillow, fists tangled in the sheets as her darling husband plunged his engorged erection in and out of her ass with the pent-up desperation of a sailor on shore leave at last. Her ass burned...and for a moment, as he bottomed out and her sphincter felt on the verge of snapping, Sue Storm wondered terribly if she could take them both at once.
