The doctor leaned forward towards her swollen breasts, pulling down his mask and revealing a white, noseless face with large, black, inhuman eyes. Regan didn't even seem remotely disturbed by his appearance, her soft gasps filling the room as he began to suckle at her sensitive breasts. Much to her surprise, the creature seemed to be gaining sustenance from her breasts. A stream of milk flowed from her nipple into the creature and she moaned in pleasure to nourish her new lover. She vaguely remembered the injection she had received earlier. Apparently, it had prepared her body for motherhood. Unbeknownst to her, her womb was now fully prepared to carry the offspring of this alien race whose desire to overtake humanity would begin with the production of hybrids with this female, whose vitals had proved ideal for housing their alien spawn. The injection had altered her ovum, making her not only dangerously fertile but changing the structure of the eggs to be susceptible only to the cum of her alien lovers, who would service her now likely until she died.
"Please," Regan moaned, though her own tongue felt thick and useless in her mouth, having a difficult time forming words, or making any sense of her situation. The alien obliged, having the straps around her ankles released while two robotic arms reached out and pulled her slick thighs apart. The alien aligned his cock with her entrance, continuing to suckle at her breast as he gave a mighty thrust and pushed his huge member into her hot, wet pussy, a satisfied sigh passing over Regan's lips.
It was better than anything she'd ever had, including all the toys and vibrators she'd amassed over the years. The thick, rigid cock seemed to swell and throb inside her as the alien rutted against her in a desperate frenzy, his bulbous head butting against her cervix relentlessly, his own need to breed intermingled with her need to be fucked. She writhed against the table, her hips bucking like crazy as half-human noises flew from her throat. The rhythmic pounding drove her wild, feeling flushed, hot, pleasured like never before. "Ahhh, ung," she cried, tossing her head as the alien switched breasts, feeding from the other as the sustenance gave him energy to continue. Deep within her abdomen, she felt her womb throbbing, begging to be filled with the hot cum of her mate, eager to be filled to the brim with as many offspring as it could hold.
"Nnnnng, ahhhh!" Regan arched her back sharply as the first waves of climax washed over her, her pussy squeezing down hard on the alien cock, as if to milk the cum from the heavenly cock. She was soon rewarded as the alien gave a sudden shudder and a flood of white hot cum flooded her womb, much more than a man could produce. The alien kept cumming and cumming, his hips still pounding against hers, until her womb was stretched and warm with the seed of her mate, her legs glistening with the excess cum that dribbled down her legs. She shuddered in the final waves of climax, feeling so thoroughly filled.
She gave a soft cry of dismay as he pulled out, a flood of cum pouring down her legs. His job was done however, as the screen showed the number of fertilised eggs. One. Two. Three. Four. Five. Five hybrid offspring were now growing in her womb, feeding off her body. The inexplicable feeling of warmth and fullness caused her to sigh in content. She could feel her motherhood already. She was ready, and more than willing.

Her pregnancy progressed at an inhuman pace and within a week, her stomach was enormously bloated. She had been placed in a small room that was pleasantly bright and was given everything she needed. For the most part she merely laid in her bed, stroking her clit and rubbing her massive stomach. One day she woke up to find herself back in the medical theatre, her legs up in stirrups but her arms free. She felt a huge pressure inside her and knew that it was time for her to see her young. Perversely excited, she stroked her sopping pussy until a bucket load of sticky greyish-white fluid gushed between her legs and the contractions began. Unlike human contractions, however, each one felt like a small orgasm, causing her to writhe in ecstasy through her labour. As the contractions grew closer together and more powerful, she started to scream in pleasure as the pressure began to move downwards and the first little one started to make its way out of her.
"Eeeeee!" she cried in bliss as she sat up, pushing hard as the top of the baby's grayish head pushed against her opening. She panted, eagerly rubbing her clit and throwing her head back as the baby slid out of her, making little noises, looking almost entirely human except for the odd, mottled skin. She bit her lip, eagerly pushing as then next offspring travelled down her body and forced its way out of her slick entrance onto the table, her body shocked by almost endless orgasm. By the time the last baby slid out of her, she had experienced countless orgasms, her legs soaked with a mixture of the birth fluids and her own cum. She panted, exhausted and sated, her stomach feeling empty now as she gathered her offspring against her and let them suckle at her hugely swollen breasts. It was the first batch of many that would be assimilated into the human race. She would be the mother of earth's downfall, but she didn't even care. All she knew, all she wanted to know, was this intense pleasure, forever.
