Begging To Be Bred

Time lost meaning. Porkum seemed insatiable. His cock never seemed to flag, his thrusts never lessened in intensity, though he sometimes entered brief periods of jackhammer speed that made Sue Storm's screams echo throughout the factory. His rough hands played with her tits, mashed them together, teased the nipples, sometimes pulling them painfully.

Yet pain wasn't his true desire. With every shift in position, with every cervix-brushing thrust that left her cunt stretched taut around the thickness of his inhuman prick, Porkum held back. He could have easily torn her holes open, yet in his own way, Porkum was being gentle. His holding back was a sign of his utter dominance of her, and for her own part, Sue had ceased trying to escape from the dick that impaled her. It was the one constant in her new existence.

The pace told on her. Due to her cosmic-ray enhanced physiology and constant exercise, Sue Storm had the body of an Olympic athlete, could have run an ultramarathon and still been able to fight at the end. She was fit enough to pass SEAL training. Yet a few hours of constant, energetic sex strained muscles that Sue Storm had seldom had occasion to exercise after the birth of her second child.

The thought struck Sue with a sudden, terrible pang.

Porkum wasn't wearing a condom. His unprotected cock pushed in and out of her stretched-out slit with terrible potential. Sue and Reed hadn't been intimate enough in months for the Invisible Woman to bother with birth control. Even if he hadn't cum yet, the sperm in his precum could—

Another small climax ripped through Sue's body. Not so much from the constant stimulation, but from the idea. The image of Porkum's massive balls emptying their billions of virile swimmers into her snatch. The Invisible Woman's breath came in ragged gasps, her body felt overheated, her hips creaked, and her pussy burned from the friction of his massive tool, yet what was getting her off now was something different. Something more primal.

"I want you to breed me," she said through cracked lips. Her body shook as she gave voice to her desires. Tired vaginal muscles squeezed the womb-breaking fuckmuscle that plundered her pussy with each stroke. A terrible aching need filled Sue Storm, an emptiness in the middle of her being. She had no idea that this was the next stage in the effects of Porkum's personal biochemical warfare. An activation of ancient instincts, an exhausted, intelligent mind trying to rationalize a biological clock that had just been set to five seconds to midnight. Sue Storm swore she could feel her ovaries throb.

Porkum was on his back now, Sue atop him. The dark eyes watched the naked heroine, dripping with sweat, feverish and lost in a sensation she had never experienced. Not unlike how other mammals went into heat. An overwhelming need to breed.

"Cum," she begged. "I need your cum. I need to be bred. Fuck your babies into me! I need you to knock me up!"

There was a note of distress in her voice, her chest heaved in sudden frantic need. Her body shook as tired muscles strained to put all of herself into pumping his cock, as if she could encourage him to pump his cock into her empty womb.

Porkum grinned. Sue Storm was right where he wanted her.
