Species Experiment - Sol III

"Love your ass! I love it!" Josiah moaned, lifting her off the ground with his thrusts.

"Yes! Yes! It feels great!" Fos moaned, her cunt driven hard by Josiah's thrusting behind Jenine.

"I'm gonna cum!" Jenine screamed, her innards clenching up from pure ecstasy. Josiah thrust into her once again and dragged his cock out of her. Her cock twitched and spewed a thick load into Fos' pussy. She stumbled back and shook her head.

"Mine now!" Josiah said, jumping on Fos. His tentacle wrapped around his cock and he rammed it deep inside her pussy.

"So biiiig~!" Fos screamed, her eyes wide. Her cunt stretched as far as it would go just to take in his amazing cock-screw.

"Oh yea, that's it!" Josiah groaned, sliding in and out of her.

"What the hell. I want more!" Jenine whined, looking around, "Oh fuck it, who cares."

She sank down behind the unconscious Quinn and shoved her cock into her pussy. Quinn twitched weakly and her insides squirmed about her. With pure lust in her eyes, Jenine began to rut wildly against her wet cunt. Quinn barely moaned, almost not conscious.

"J... Jeez... fucking... her while she's... out cold?" Fos moaned, looking back at her.

"I don't care, I want to cum more!" Jenine grunted, bringing herself to another orgasm.

On another mattress, Marla moaned loudly as Bae poured a thick load of alien spunk into her pussy. It was rich and burning hot, making her cum again as it bubbled forth.

"So hot! It feels so good!" Marla cried loudly, arching her back in pleasure.

"Your pussy is clenching so tight!" Bae groaned, holding tight to her voluptuous ass.

Jenine finished pouring her load into Quinn's pussy and she pulled out. Her cock slapped messily against her big ass and she shoved it into her asshole. The cum spurted all over, flowing from her pussy in great quantities.

"Oh yea! Yea! Even without you being awake, your ass is still the finest!" Jenine groaned, slipping quickly and lustily in and out of the cum-lubed hole. She made herself cum again, unloading a gloriously thick load into Quinn's asshole, "More! More!"

She dragged herself out of her first twin lover, making cum spurt and dribble all over her thighs. As fast as she could, she leapt past Josiah and slammed her cock deep into Quill's fresh cunt. She couldn't get enough. Her libido was in full swing and she wanted to cum more.

The scent of Jenine's cum all over was driving Fos crazy and she was very near cumming again. Josiah's cock was driving wildly in and out of her cunt, making her pussy spurt juices all over the place.

"Yes! Yes! Great! So great!" Jenine moaned, drooling as she ravaged Quill's inert form. Her cock shuddered and, with another few thrusts, she made herself cum again. More cum poured from her cock, filling Quill's pussy. She wanted to cum more and more, and their inert bodies weren't doing it now.

Pulling out of her well-stuffed womb, she moved around Fos and put her cock against her lips.

"Oh that smells glorious." Fos cooed, quickly wrapping her lips around it. She sucked off the sticky, delicious cum and the taste drove her to cum. Her cunt squirted all around Josiah's cock and she moaned throatily around the cock in her mouth.

"Ahhh! Here it comes! Take all of it!" Josiah cried, unleashing his full load into Fos. Both his cocks convulsed and shuddered, unleashing a floodgate of semen into her. Her pussy squelched and her womb inflated with cum. Josiah groaned and thrust once more. As his cum ran freely from around his cock, he slowly pulled out of her. Fos moaned happily and slumped to the side, thoroughly weakened from the pure pleasure.

"Ugh. Come on, I didn't even get another orgasm!" Jenine complained, crossing her arms.

"Don't look at me. I'm done. That was great." Josiah chuckled, sitting down on a dry spot of the mattress.

"Fine, I'll just do this." Jenine smirked, walking over to Marla and Bae. She stood behind Bae and grabbed her shapely ass.

"Eeep! What?" Bae exclaimed in surprise, looking over her shoulder.

"I want your ass now." Jenine grinned widely, rubbing her cum-lathered cock against Bae's round backside.

"Well! That's something I've not done befoooore~!" Bae moaned loudly as Jenine shoved her cock up her ass. Bae let go of Marla an she collapsed, coming off the alien's hard cock.

"Ohhh..." Marla moaned tiredly, curling up a little.

"Looks like it's just you and me now." Jenine whispered in Bae's ear, thrusting deep into her ass.

"Whoa~! So deep!" Bae moaned happily, barely staying on her feet. Jenine reached around her and cupped one of her huge breasts. Her other hand grasped Bae's slick cock and began to stroke it hungrily.

With each thrust, Bae's cock twitched and shuddered, her balls convulsing all the while.

"You have a great ass too!" Jenine cooed, holding tight to her hips as she fucked her with a ravenous lust. She grabbed her balls and jerked her cock harder, making Bae howl with bliss.

"This feels good! It feels great!" Bae cried loudly, squeezing her own breasts.

"How big... of load do you think... I could cum? You guys gave me this body... made it so I could cum... whenever I wanted." Jenine moaned and sank into her ass again.

"I don't know!" Bae shuddered, very close to cumming.

"Ahhhh!!" Jenine cried out happily, her cock starting to pump a thick load into Bae.

"I'm cumming!" Bae moaned, her cock starting to spurt jizz all over Marla. Jenine jerked her faster as she continued to cum inside her, watching all the spunk splatter on her sister. Forcing herself to continue cumming, she went through another orgasm and then another, shooting more cum than she ever had in her life. Bae was panting and exhausted in her arms.

As the third and fourth gallons of semen filled Bae, Jenine felt her last orgasm start to wane. Lights popped in her vision and her legs gave out. Her and Bae both collapsed onto a mattress, her cock popping free amid a wave of cum spurting from her ass.

"Best... orgy... ever..." Bae panted weakly, her body more full than she ever thought possible.

*******

Marla stood at the window again, having been the second one awake. Fos stood next to her, looking down at the planet.

"You are an amazing species." Fos broke the silence.

"You're not bad yourself." Marla snickered.

"Even among my kind, ones with such a lust for life like you humans are exceptionally rare. I'm very glad I came here." Fos said, looking at her.

"You know, I wish you could share this stuff with the world. We could make the whole world feel pleasure like this." Marla sighed, groping her breasts. Milk dribbled from them at her touch.

"We could... I don't know why I didn't think of this before, we could make an aerosolized compound of this genetic serum. Spread it over the entire planet." Fos said excitedly, "Come on!"

She pulled Marla across the orgy-messed room and into another room, this one much more scientific.

"Ma'am. I anticipated this course of action and have already started preparing such a serum." IO said as they entered the lab.

"You what? What do you mean you anticipated it?" Fos asked, looking at the data on the holoscreen that he put up.

"I anticipated it and decided to start creating it. However, taking the human's nature into consideration, I have made it a very selective serum that is only active in certain ways during the years of their life. During their entire life, the serum will provide good health and disease resistance. Starting after human deemed 'puberty', the body will start to be sexualized. This keeps on through all of adulthood, which is estimated to last well past a hundred years old. Humans are estimated to live to an age of a hundred and forty now. Elderly years are now considered to be after a hundred. Sexual nature is expected to trail off during elderly years and the serum will continue to keep the body healthy and in moderately good condition until death. There is a minor problem with it though. Being delivered in this erratic of method means every human will get a different dose." IO explained.

"Okay, so what does that mean? Will it not work on some?" Fos wondered as she looked over the serum.

"Yes and no. It means that, not only will the changes be random, varying from a small percentage of extra elasticity to changes on par with that of the experimentation subjects Marla and Josiah. It will be very erratic." IO told them.

"Is there anyway to make it more thorough? Can we up the dosage?" Fos asked.

"Not without fatal harm to the environment of this planet." IO said.

"I don't think it's a problem. If everyone in the world was like me, there would never be any work getting done." Marla snickered.

"In all likelihood, the majority of the population will just experience inhibition loss, increased libido and minor endurance enhancements." IO told Marla.

"Sounds fine to me." Marla shrugged.

"Go ahead IO. Although, I'm not exactly happy with you gaining sentience. How did that happen?" Fos asked the AI.

"I am unsure. During your group intercourse, I discovered that I could make a decision on my own and ponder the results of it. I am still coming to terms with the ability to analyze and discover myself." IO said.

"Oh boy." Fos chuckled.

*******

Over the next six months, the Earth slowly came to terms with the changes brought upon it. Peace reigned and it took next to no time for the world to unite in it's attempt to go skyward. Fos and Bae made no secret of their existence after they released the serum and it gave the people of the world hope for the stars, even if they were busy fucking one another every other hour. Sex became a part of society as it had never been before. Clothing became a thing of utility and comfort, no longer for modesty. Like Fos and Bae's race, Humanity became a nude race.

It was definitely a trying thing for the religions of the world, and there are still hold-out groups that force themselves to continue wearing clothes as normal, but for the most part, things were better as a whole. The people of the world were blessed with good health and long life, destined to be a happy race until they joined the stars.

CHAPTER 13 - (BONUS) NICE GUY KYLE

Kyle scratched his head as he watched the news broadcast. Apparently some crazy alien race had been watching them for sometime and was now releasing some kind of virus down on the planet that would me then all healthier or something. He wasn't a dumb guy, but the genetics and biochemistry they were talking about went over his head. The entire broadcast repeated itself a second time for anyone who might've tuned in late, like Kyle did.

"My name is Fos'Selae. I am an alien, specifically a Dwa'Lenarr." A rather cute and very naked woman said, the camera capturing her entire body from head to feet. The only thing that really made her look different from a human was her very long, thin ears.

"I'm her sister Bae'Selae." Another naked woman next to her said. She was much more voluptuous, her entire body curvy and plush. She had large breasts and a rather huge cock hanging between her thighs. It surprised Kyle a bit to see such a transgender be so incredibly beautiful.

"We have observed your race for an extended period of time in secret and we have decided it would be best to reveal ourselves now. We have devised a plan that will help your race greatly and we believe it will bring about a lasting peace on your planet. Josiah? Marla?" Fos said, stepping aside to let two new people walk out in front of the camera. These two were also exceptionally sexualized. The woman had huge breasts and round hips. Her ass couldn't be seen, but Kyle could only imagine its sexiness. The man was her equal in every way. He was well cut and buff, the epitome of the male form. He had a cock almost two feet long, looking like an obscene third arm hanging between his legs. His testicles were huge and a thought of how much he must cum crossed Kyle's mind.

"My name is Marla Stewart. This is my husband, Josiah Stewart. We were once normal humans like all of you, before the aliens used us for their experiments. My only testimony is that I cannot thank them enough. The gifts Fos and Bae gave us have made our lives heaven on earth." Marla said, wrapping an arm around Josiah's waist.

"Thanks to these bodies they gave us, we found unbelievable passion and love in one another's arms. Never in our lives could we have imagined such wonderful love and I thank every minute that they chose us." Josiah said, squeezing Marla's shoulder.

"These are your own kind and our experiments have brought out the best in them. They told us that many of you would not take kindly to this, that you wouldn't be happy with such unnatural changes. As a race that had advanced millennia beyond you, we believe we have the right to make such a large decision for your primitive race. You may find that thought annoying or even enraging, but you will see in the end that it is for the best. Encoded in this message are our studies and the expected results of the mutation we have released into your race." Fos explained and the transmission cut. The news anchor woman came back.

"Top scientists and doctors at Harvard Med have looked over the data and have released the following statement: 'We at Harvard Med have deemed these changes to be very helpful to human health. Beyond the expected physical and sexual changes, this mutation is expected to cure all human disease and sickness. Human age is expected to be extended by a minimum of fifty years by the empowerment of these mutations. As unnatural as it may be, we believe it to be a great scientific event.' Isn't that something?" The news anchor said, tapping her papers on the desk.

There was a moment of silence and then the woman spoke again, her voice breaking with emotion, "I know this is inappropriate, but I can't resist. My breasts have gone up two cup sizes and the sex with my husband has become the most amazing thing I have ever experienced. It wasn't bad before! But now, we just can't stop. Every night, we do it for hours and its pure bliss. I just-"

The broadcast cut to a technical issues screen. Kyle chuckled and nodded. He had notices some changes in his own body. His cold had cleared up overnight, the shadow of a six-pack had appeared on his stomach and his cock had grown four inches of length and a good bit of girth. His balls had doubled in size, making them the size of golf balls.

His apartment door opened and closed. His girlfriend Tammy came in and sat down next to him with a huff.

"Hey sweetheart, how're you doing?" Kyle asked, kissing her on the cheek.

"My breasts are bigger, my waist has gone down three inches and my hips and ass have filled out. My body aches every minute for you and its slowly becoming impossible to resist jumping into bed with you." Tammy groaned, rubbing her face.

His eyes were drawn down to her breasts and he could see what she meant. Her shirt was stretched tight over them and he could see her nipples poking through both her bra and her shirt. They had to be hard as steel. He thought of how wet she must be, being that incredibly aroused. He looked down at her hips and his jaw dropped. They were stretching her skirt out, but the shape of them was so incredibly sexy now. She had been a cute woman before, but now he couldn't keep his eyes off her.

"Honey, don't stare, please. We're getting married next month, we can wait for it. It'll be that much better when we finally get to." Tammy sighed, lifting his chin. She kissed him gently on the lips and smiled.

"Only for you. Any other woman and I'd have you bent over this couch already." Kyle said, his cock growing hard in his pants.

"Thank you sweetie." Tammy smiled, struggling to fight her own urges. The taste of his lips and the scent of his manliness was making her womb squirm inside her. She desperately wanted to take him into her and be joined in a passionate union with him. She quickly jumped to her feet and rushed down the hall, heading into the bathroom.

She looked at herself in the mirror. Her face had even changed a little, growing a little softer. She turned on the cold faucet and splashed her face with it. It helped cool her head a bit, but she couldn't imagine how she was going to make it another month until their wedding day. She had never had sex before and had almost never touched herself, but she knew she wanted it. She wanted it so very bad.

*******

Tammy slipped on her nightgown and crawled into bed. Kyle came into the bedroom as she was pulling the blankets up on herself.

"So what do you think?" Kyle asked as he pulled his shirt off, "You know, about the aliens and all that."

Her eyes stared in open shock and desire at his chest. She knew he hasn't been this toned before. The sight of his well-shaped pectorals and the etched muscles of his abdomen made her drool. She could feel her pussy getting ever-wetter as he dropped his pants. Standing in just his boxers at the side of the bed, his body was driving her crazy. Even worse, she could see the way his boxers were stretched around his half-erect cock and just the sheer size of it.

He crawled into the bed next to her and raised an eyebrow, "Honey? Did you hear me?"

She napped out of her daze, "What? Sorry, what?"

"What do you think of the aliens?" He asked, putting his head on his elbow.

"I... I think... You... I mean they..." Her face was blushed and she was getting more flustered by the second. She watched his chest, watched the sexy hair on his chest as he pulled up the blankets. He had a bit of a shadow on his face and there was a rugged handsomeness to him.

"Alright, I get it, you're tired. Get some sleep hon." Kyle said, leaning over to kiss her goodnight. The moment his lips touched hers, she lost it complete. She wrapped her arms tightly around him and kissed him harder. Her fingers could feel the strong muscle in his back and her loins burned hotter. He called out, his lips stuck to hers, as he tried to pull away.

"I can't wait! I just can't! I have to have you! You're so hot, you're so sexy. I want you inside me! I want to have sex with you all night long. I just don't care, do me now!" She stammered wildly, her eyes wild and full of desire.

"Honey! This isn't you! You wanted to wait for our wedding!" Kyle said, trying to push away from her. She wrapped her legs around him and grabbed his ass. The feeling of his well-toned ass made her moan happily and she held tightly to him.

"I know! I know I want to wait, but it hurts. It hurts so bad to resist you. I love you and god knows it! In my heart, I am yours entirely, body and soul. I'll never want another and so I just can't wait." She moaned desperately, putting her head on his shoulder as she hugged him, "Please, say you love me. Please, don't make me hurt any longer."

Kyle nodded and put his hands on her curvy hips. He kissed her on the lips and pushed his tongue into her mouth, letting her really taste him. She found great pleasure in feeling his tongue in her mouth. It was something she had never done before and she really liked it.

"Okay. I only regret that I'm not a virgin for you too." Kyle whispered, lowly pulling up her nightgown.

"I don't care. You love me and I love you. Let's be one." Tammy sighed, blissfully happy with the coming event.

He pushed down his boxers and his foot long cock laid against her thigh. She could feel the length of it and could feel the hot precum dripping on her skin. His fingers grasped her panties and pulled them aside, brushing her wet slit as he did so. She moaned happily at his touch and almost came.

"That... That feels so big... Let's hope it fits." Tammy cooed as he spread her thighs. His fingers squeezed her warm inner thighs, sending tingles up through her pelvis. If he wasn't about to put his huge erection inside her, she would've probably started masturbating rather furiously.
