A knock at the door.

The creatures had been playing with him for some time, while he remained trapped behind his own eyes. He could hear his only hope for help struggling in the bedroom, just as helpless as him. Then a tiny knock at the door, instantly halted the worm's and they moved him to answer the door. Alex panicked, shuddering to think of what loathsome creature would be on the other side.

When the door opened he was shocked by a beautiful woman wrapped in a loose lab coat. Her face was picturesque, and here eyes radiated a depth that stole his words away from him.

"Ah, you must be Alex" She said, calmly, dispite him staring at her while completely naked and caked in drying cum "I see you met my experiment. You don't have to say anything, I know that you can't. May I come inside?"

She quickly stepped past him, and his body closed the door behind him.

"I'm pretty sorry about all off all this Alex, I know it's not fair. But this research represents an important leap in gene editing, and I couldn't let my work be disturbed."

"Yes," the worms said in his mind. "This is good, don't fight it."

"You don't need to understand or approve," She continued "But, you will enjoy this at least"

Alex was petrified now, he tried to scream, but no sound came out.

"Are the females subdued?" She asked the creatures inside him.

After a nod, she said coolly: "Then lets begin, sit."

The worms mechanically maneuvered him to the couch, sitting him down near the edge so he was leaning back, with his hard cock standing proudly erect. The gorgeous woman began to take off the lab coat patiently, slowly revealing pale naked skin underneath. The heavy coat rolled over her shoulders, exposing a swollen abdomen on her slender form. Her pouting belly made her look so clearly pregnant that Alex wondered how she hid it under the coat. Alex couldn't feel a tinge of real arousal watching the gorgeous girl undress in front of him. His eyes drifted up and over her plump breasts and met her beautiful eyes.

"Are you ready?" She asked the creatures. They nodded, but Alex also meekly accented, from within his prison.

The naked girl stepped onto the couch and straddled Alex, standing tall above him as the creatures stared and resumed stroking his cock slowly. She stood tall and closed her eyes as she ran a hand down over her pale skin. Another hand began to cup her left breast, slowly massaging it as her right began to massage her pink lips. She sucked in air as a finger found her clit. She looked down, seeming to remember that he was there. And she smiled devilishly as sh saw his cock. Alex could do nothing but stare helplessly and enjoy the sensations as the woman masturbated above him. She looked into his eyes for a moment, and whispered over the growing squishing sounds of her fingers.

"Here she comes baby"

The woman moaned again and threw her head back. A small gush of fluid shot from her pussy, stunning Alex momentarily. He could feel his arousal growing as the jelly soaked his skin. Then he saw a tendril emerging from her tight slit. She moaned gutterally and collapsed to her knees leaning her upper body against his. Alex was revolted by the creature the woman was birthing, but the aphrodisiac was kicking in and he wanted her so bad.

She moaned again deeply as she feverishly rubbed her clit, coating his crotch in more slimy goo. Alex was pinned under her, and even the worms struggled to rub his cock under her weight. He felt feverish or high as more of the stuff soaked his skin. Alex forgot his panic until the tendril wrapped itself around his dick, and began to pull. "What the fuck is happening" he thought. The thing tugged, pulling hard, causing the girl to gasp each time.

For a moment he thought that the thing was trying to align his cock with her opening, but then it pulled itself out of the woman, dropping with a wet plop onto his abdomen. He couldn't see the infernal creature but it felt soft, wet and hot on his skin. It's grip began to coil around his shaft, holding it firmly.

"Don't worry." She said sleepily. "There is nothing you can do now, it's got you."

Alex couldn't even talk if he wanted to, but his hand stopped stoking. The creature's circled around the head of his dick before slowly sliding it's strong but fleshly tendril into his hole. The pain was unreal, but somehow distant, and the pressure made him feel like he was close to cumming. It sank deeper into him, sliding along with the slimy lube that coated half his body. Even the worms shuddered and goosebumps covered his body.

"Shhhh," she whispered, still panting "You should enjoy this, and its for science."

The mysterious creature penetrated him more, stretching his hole as the tendril grew wider. He choked out a cross between a moan of pleasure and sound of the wind getting knocked out of him. The girl rolled off of him to sit beside the orgiastic mess, and resume rubbing her pussy.

"I've been working on my creature my entire life, it's my baby, no pun intended."

Now that Alex could see the creature it looked radically different from the other worms. This creature was light pink and narrower. It's body was about the size of a pen, and it had several marble sized bumps along it's body, one end had an array of tiny tentacles, while the end buried in his cock seemed to taper off to nearly nothing. It resembled a long, slender squid more than anything else. Alex could feel the thing pulling itself deeper into him with the one end.

"I've designed every part of this creature" she said through moans "Once It's inside you, this parasite will use your body and dna to serve my every purpose. You will make a great host, that is why I picked you for this experiment."

Alex grunted as the tubular creature continued to struggle into his rigid cock. The wider sections were reaching the tip, and it clearly wasn't going to fit easily. As the larger marble shapes bumped against his stretched hole the little tendrils flicked the fluid against its sides.

"You see, each of those bumps is a specially engineered ovary that she is going to plant inside you. These parasites need a host to reproduce, and you are the only man on the planet that currently has enough of their dna to fertilize the eggs."

Alex screamed as the first one popped inside his urethra, he wanted to pull it out, but could not escape the **** urge to push it deeper.

"I know that her mating is a little more aggressive than we are used to, but I've made it as enjoyable as possible. See, she is going to climb inside your scrotum and begin to lay her eggs. They can then grow inside you until they are ready to be laid, you are going to be a mother!" And with that, she began to shudder and orgasm next to him.

Alex looked down in horror as ovary after ovary began to sink into is tortured cock. He could feel it moving within his pelvis, sliding inexorably toward his sac. He felt an orgasm rock him, but the creature blocked every drop from escaping.

"Sorry," she said panting. "You are going to need every drop for her eggs, you two will be fertilizing them for the rest of your lives. I just hope that when her nerves fuse with yours that she leaves some of you to enjoy it."

BAD END
