A Year

Twelve months. Fifty-two weeks. Forty dirty, sex-drenched nights and weekends with Porkum, strung out like black pearls over the course of a whole year. In all of her life, Sue Storm had never watched her monthly cycle so closely. She had worked doubly hard to avoid any hint of suspicion from Reed and her family, always washing herself meticulously clean before she returned home. In her own way, she was faithful to both her husband and her lover; presenting Reed with the image of the faithful wife whose libido had finally subsided to the mere birthday and anniversary blowjob, and flushing her birth control pills and taking the daring risk of Porkum's prick inside of her pussy unprotected for each and every sexual encounter.

Sometimes he would just have her lay back, holding her pussy open as he jerked off into her open hole. Sue had thrilled in mingled terror and excitement as he spat his swimmers into the depths of her cheating cunt. Sure that she had done the math right, that she wasn't ovulating, that the chances of conception were minimal.

So far, she had been right.

It was Doom who finally took things in hand, when it came time for their anniversary. The small golden fertility charm, ancient and primitive in its construction, lay on a metal ring and was looped about by a thin chain. The pig-man mutant did not ask for details of how it worked. He only surprised Susan with is latest gift, his latest order for "his" cunt. She had flinched as the needle pierced her navel, though it didn't really hurt much. Then he had wrapped the chain loosely about her waist, and fastened it to the ring.

The small, bulbous belly and pendulous bresats of the magical charm hung there, pregnant with possibilities.

"The chain's a bit loose, Porkie," Sue said with a grin. It hung down to her thighs and ass, though small enough that it wouldn't be visible beneath her tight-fitting Fantastic Four costume.

"Only 'til your belly swells up," Porkum countered.

Was there something different, that time, as Sue lay on the edge of the bed and bared her raw and unprotected pussy for Porkum's prick? She knew that the year of sex had changed her. The fat cock had stretched her holes out, and she'd taken to shaving her labia bare, the better to avoid cum getting caught in her pubic hair. She got wet easier now, and there were nights—dangerous nights—when she was alone in bed, an invisible dildo in her cunny as she writhed in the grip of an erotic need she dare not satisfy. So fertile at times she felt like even a drop of sperm would knock her up.

Porkum's prick bottomed out inside of her. Her stomach distended as he **** as much of himself into her slit as possible, and the little golden fertility charm wobbled and almost seemed to sparkle in the light as he unleashed the first massive torrent of seed.

I'm safe, Sue thought to herself as she thought back to her ovulation tracker app. The very same app that Doom had hacked and subtly adjusted, weeks ago. So that rather than this being one of the safe times of the month, Sue was right in the middle of the most dangerous part of her cycle.

Not that she knew it. Not that she even dreamed of the forces that conspired against her. The Invisible Woman grinned up at her lover and drummed her heels on his ass as she urged him to greater efforts.

"Come on Porkie! Put a bun in my oven! Knock me up, if you can!" she challenged him, with the utter faith that it would never happen.

Later in the evening, Sue was on her side. Her pussy was sore, stretched, constantly drooling with his cum. Yet Porkum was oddly fixated on her pussy tonight, not even deigning to use her mouth or ass. His hand held her belly as he slowly slid his dick in and out of the Invisible Woman's gash with long, slow, deep thrusts that squelched with every movement.

"When you do catch," he said. "What are you going to do?"

Sue grinned at him and rolled her head back to kiss his snout.

"It's your cunt," she whispered, lost in the sexual intimacy. "You tell me?"

Weeks later, Sue Storm's period finally failed to arrive.
