Species Experiment - Sol III

Dribbles of white cum began to come from her pussy and Quinn sucked it out of her. She moaned sporadically as Jenine's cock hardened inside her, stretching her pussy both wider and deeper. She began to thrust lustily, loving the feeling of finally being inside one of the twins. Her hands rubbed over the curvy ass before her and she held onto the thick hips. Her fingers sank easily into the soft flesh and she humped wildly.

"Ahhh! That feels good!" Bell moaned loudly. Quinn licked her pussy while Quill sucked on her nipples. The pleasure was exceptional, almost as wonderful as Josiah's cock.

Quill slipped a finger into her own pussy and stifled a moan. She continued to pleasure Bell, playing with her breasts and kissing her passionately.

"Yes! Fuck your pussy is awesome!" Jenine moaned, leaning over her soft body. She listened intently to the loud, wet slapping of Quinn's ass against her crotch. She grasped her lover's breasts and gently played with her nipples.

"Ahhh! Jenine! You're... you're so big!" Quinn cried happily as her pussy was wildly plowed by the lusty futanari.

"I want you now!" Quill growled, pushing her on her back. She turned around and straddled her backwards, pushing her pussy into Bell's face, "And I want that."

She licked down Bell's wet pussy, making her moan loudly. The touch on her clit was driving her to new levels of pleasure. More dribbles of white cum came out of her aroused pussy and Quill licked it up.

"Awww... Ah~!" Quinn moaned loudly, both annoyed at losing her pussy to lick and incredibly pleasured by the huge shaft in her cunt, "Ohhh! More! Pound me harder!"

She grasped the edge of the couch and held on as her pussy was slammed with a hard rod. Jenine's fingers sank into her boobs, squeezing and holding on while she thrusted.

"Ohhh yea, get your tongue in there..." Quill cooed, rubbing her big ass around on Bell's face. She could feel her tongue sliding in and out of her lips.

"I'm gonna cum! Quinn! Where do you want it?!" Jenine grunted, slapping against Quinn's spacious ass again and again.

"In me! In my womb! Fill me with your seed!" Quinn cried happily as Jenine's cock sank completely inside her. She howled and semen spewed into her, making her pussy stretch gloriously.

"Ahhh! It feels so good to cum!" Jenine moaned and giggled, falling over backward. She pulled Quinn with her and the two of them fell flat on the ground. Quinn's big ass bounced on her lap and she moaned loudly. Cum spurted out of her and all over Jenine's lap. "Ohhh! God I love your ass."

She rubbed and squeezed Quinn's big ass on top of her, gyrating her pelvis around to nestle her cock even deeper inside.

"Looks like she's gotten her load." Quill smiled as she looked up from Bell.

"God I could use a cock." Bell sighed, leaning back from Quill's squishy bottom.

"Well it's mine first." Quill giggled, jumping up. Her ass jiggled as she walked over to her sister, "Up you get sis, come on. It's my turn."

She grasped Quinn's hand and helped her get off the hard cock. Cum dribbled from her pussy and ran down her thighs. Quill gave her sister's big rump a slap, making it shake in a very sexy manner.

"Oooh! Alright!" Quinn squeaked and laughed, moving out of the way.

"Come on, I want to try your pussy now too." Jenine said, holding the base of her wet cock, "Get that gorgeous ass over here."

"Yes ma'am!" Quill smiled, crouching over her. Her pussy dripped with eagerness as she felt her insides seemed to squirm with lust. She very nearly came when her pussy touched Jenine's cock. Her legs shuddered and gave way, making her fall completely on it. Her big ass slapped loudly on Jenine's wet lap, making very lewd sounds. "Ahhh! So biiiig~!"

"Oh god! Your pussy is ever bit as good as your twin's. Squeeze me, yes!" Jenine moaned happily, staring at the huge ass on her lap. She kneeded it and pulled down on it, reveling in the burning heat of her pussy.

"So deeeeep!" Quill moaned, holding on Jenine's knees as she slid up and down.

"Come on, lick me, finger me! Pleasure me! Please!" Bell moaned, reaching out to Quinn. She grabbed her ass and teased the soft flesh, feeling about the big round butt. She leaned forward and got off the couch, kneeling behind Quinn. She leaned forward, spreading Quinn's big butt cheeks to lick at her ass. She could taste her pussy juices mixed with Jenine's scent.

"Ohhh! Oh yes!" Quinn moaned in surprise. She had been so intent on Jenine and her twin that she hadn't heard Bell's begging.

Bell crawled around her and put her mouth to her pussy. She began to lick Jenine's cum from her while holding onto her beautiful butt. Quinn moaned loudly, putting her hands on Bell's head. She felt her sucking Jenine's cum from her pussy, loving the delicious flavor of their mixed juices.

"I want to taste yours too." Quinn said, flopping back on the couch, "Upside down, come on."

Bell nodded and turned around. Quinn grasped her hips and pulled her crotch up to her face. Bell squeaked in surprise as she was pulled up her. Her pussy was lifted before Quinn's mouth and she began to lick and devour voraciously. She spread her thighs and Bell began to lick at her pussy. Quinn kept her arms wrapped tightly around Bell's middle, face deep in her cunt.

"More! More! Ahhh~!" Quill cried out, bouncing wildly on Jenine. Her big ass jiggled with her desire and lust, driving Jenine's cock deeper and deeper.

"Quill! Quill, it's so hot inside you!" Jenine moaned loudly, holding onto her hips, "Yes, I'm cumming again!"

She thrust up into the second twin and her cock erupt like a lusty fountain, filling her in moments with hot seed. Quill screamed in pleasure as she orgasmed as well. Her heart pounded wildly as ecstasy like she had never felt poured through her body. She could feel her womb stretching from the amount of cum being shot into her.

"Ahhhh yes!" Jenine cooed joyously as her cock spurted the last of this orgasm into her cunt. Her own pussy shuddered with pleasure, loosing some girl-cum on the floor.

"That's so good..." Quill sighed happily, sliding sideways off her dick. She slumped on the floor with a soft exhale.

"More. I want more!" Jenine said, seeing Quill's inert body, "Give me more pussy!"

She got to her feet and looked at Quinn and Bell on the couch. She grasped Quinn around the middle and pushed her off to the side of the couch, making her squeak in surprise. Without further waiting, she spread Bell's thighs and rammed into her cunt.

"Ahhh~!" Bell cried out loudly.

"Yes! That's it! More! More! More!" Jenine moaned, thrusting animalistically. She held onto Bell and rammed harder into her. Her cock was really starting to get going and she couldn't get enough pussy. It was like back with that team of cheerleaders, her mind just went mad with desire. She wanted to cum more, to feel more tight, warm holes around her shaft. Drool ran down her chin and she pounded Bell ruthlessly.

"Whaaaa~! So good! So big!" Bell moaned happily.

"That's it! Yes! Squeeze that little cunt tighter!" Jenine grunted, wrapping her arms tighter around Bell. She grunted and thrust, only caring about her own pleasure at this point. Her cock was hard and showed no signs of stopping as it throbbed with endless lust.

"Ohhhh Jenine! More! It's so good! Fuck me harder!" Bell cried out.

"Harder? You want harder?! I'll turn you into a pile of useless lusty flesh!" Jenine yelled, ramming harder. She took Bell's comment as a personal insult, vying to prove her wrong in every possible way. Her hands gripped Bell's hips tightly and she piledrived her lovely pussy. "Take it! Take it!"

She screamed more and pounded against Bell's cunt with every bit of lust she could muster. Her spit dripped down her chin as her tongue hung out of her mouth. She moaned and grunted like an animal, clearly not interested in being gentle. Her cock was hard as steel, making Bell's abused cunt stretch more with each thrust.

"Now take all my seed!" Jenine howled at her. Her cock came stronger than ever, firing like a hose inside Bell. She moaned and thrust, spurting nearly a gallon of thick seed into her pliable pussy. She thrust again and again, making the cum spurt all over the couch.

"Ahhhh... haa... haaaa..." Bell panted weakly as her orgasm-wracked body slowly went limp.

"More! Quinn! I want your asshole!" Jenine cried, pushing Bell out of the way. She clambered up on the couch and grabbed Quinn's body. She rolled her over on her belly and marveled at the glorious round ass. Her body was so lean and tall, except for this beautiful, sexy backside. Jenine was so horny just looking at it and she couldn't help laying her cock between the tight buns.

"Oooh!" Quinn squeaked at the cock slipping between her cheeks. Jenine's fingers sank into her big, glorious ass, squeezing the soft cheeks to either side of her cock. She thrust against her ass, rubbing against her hot ass crack.

"Yea, yea. Look at that ass. My god, that is a glorious ass! Watch it jiggle!" Jenine said, slapping her big ass. It jiggled and bounced about, making each thrust more pleasurable. Her ass grew wet with the juices on Jenine's cock and the precum dribbling from her. "I'm going to fuck you so hard!"

She pulled back and dove straight into her sweaty asshole. The hard shaft slid in with little resistance, piercing deep up her anus. Her butt squeezed tightly, making Jenine moan happily. Pushing down on her gorgeous, brunette lover, Jenine pounded deep into her ass.

"Ahhh! My ass! So good!" Quinn moaned happily. The way the cock moved unstoppably in and out of her shuddering rectum made her scream with ecstasy. It was heavenly pleasure and she could only imagine how good it would be if she could have another cock in her pussy too.

"Yes! Oh your ass is top notch! Fuck yes!" Jenine screamed, spreading her legs to better pound her hole. She positioned herself above with her cock pointing straight down at Quinn's asshole. She squatted and drove her shaft completely into the tight hole. In this new position, she reached a new speed of pistoning, driving Quinn's asshole so hard that she began to cum immediately. Her pussy squirted on the couch and she moaned in joy, grabbing the edges of the cushion.

"Jenine! Jenine, yes!" Quinn moaned loudly, her eyes slowly rolling back in her head. Jenine felt her asshole clenching tightly and she came for a fourth time today. Her cock erupted like a geyser, painting Quinn's innards with delicious white spunk. She kept thrusting and cumming, unleashing all she had into her ass. She stood up with a loud moan, splattering pearly cum all over Quinn's big ass. Her cock twitched and started to rise again almost immediately. With the twins around and their big, glorious asses naked before her, she just couldn't get off enough times.

"More! More! I want to fuck more!" Jenine growled, jumping off the couch. Quinn and Bell were both unconscious and Quill was half-asleep on the ground. That was good enough for Jenine and she was going to destroy her ass just like she had done to her twin's.

Crouching behind Quill, she began to rub her ass around lovingly. Her cock dribbled precum about her big, pudgy ass. She knelt down and put her cock between the cheeks again. This time she wanted to just see the big, round ass completely glazed in seed. Then she wanted to lick it clean and give her a nice bite on the ass.

"Mmmm..." Quill moaned quietly as the dick laid between her cheeks. Jenine squeezed them tight together and began to thrust back and forth. She dragged her long, cum-wet cock back between her cheeks, loving the warm, deliciousness of them. Sticky cum wet her entire buttcrack, making Jenine's thrusts quite pleasurable. At this point it wasn't going to take her a long time to cum. She squeezed and kneaded her beautiful, thick ass, driving the cock harder in and out of it.

"Ahhh! What an ass! What an ass! I love your butt!" Jenine moaned lustily, hot-dogging her cheeks harder, "I'm going to glaze it soo good~!"

She cried out and came, standing up with her hands around her cock. Cum spewed all over the beautiful, glistening cheeks. She jerked herself wildly, making thick ropes of goo splatter all over the place. It ran down her hips and pooled between her thighs. She continued to cum and cum and cum, unleashing all she could as she stared at the perfect ass before her. She couldn't believe how sexy it looked all glazed in her spunk. She dribbled out the last of what she had, finishing her beautiful frosted ass.

"Look at that glorious sight." Jenine smiled, kneeling down behind her. She put her hands in the cum that covered her perfect ass and began to play with it, rubbing it around and squishing it between her fingers. She leaned down and ran her tongue up her crack, licking up a big mouthful of delicious cum. Swallowing it with glee, she continued to lick around her big, soft ass, swallowing all that she could. Smiling widely, cum dribbling down her chin, she gave Quill a bite on the butt. She was too exhausted to react to the bite mark.

Standing up, Jenine looked around. She felt good, very good. It had been a wonderful time with both the twins and this random waitress. Apparently she had been fucked by Josiah and Marla, but that didn't matter to Jenine. Her dick was satiated and she was finally feeling relaxed.

"You two are gonna come home with me. I want to sleep with you forever." Jenine cooed, laying down on the floor. She put her head on Quill, using her big, soft ass for a pillow. The warmth and squishiness of their backside quickly soothed Jenine into a soft sleep.

CHAPTER 10 - FURTHER TESTING

Bae was closely observing their experiments when Fos slipped into the science lab.

"What's going on?" Fos asked.

"They're fucking more. It's just pretty hot to watch." Bae chuckled, idly stroking her erection.

"You've been watching them like that for days. Would you like to just bring them up here?" Fos asked with a smile.

"What? No! What do you think I am? A perv?" Bae scoffed.

"How about this, I've been curious as to what aspect we've changed them so I say we bring them up here to test their bodies. Let's see just how far we can push them. How much milk can she make? How much cum can he shoot? How far can she stretch? How big can he get?" Fos rambled, waving her hands about as she gave suggestions.

"That sounds good. Let's try that. Bae nodded, typing on the console. She targeted their experiments while they slept off another wild session and teleported them on board. It took barely a minute for them to appear in the cells in front of them. However, one thing happened that they hadn't been counting on.

"Huh... What? What's going on?" Marla mumbled and sat up, having been awoken by the teleport itself.

"Put her to sleep for now!" Fos said.

"No wait! Stop!" Marla called, scrambling to her feet, "I want to ask you something!"

"Yes, we're aliens. Bye bye. Sleep time." Bae said, waving at her.

"Nooo~!" Marla squealed, putting her hands on the clear wall.

"Wait, why the hell didn't you colorize the cells? Why are they transparent?" Fos accused Bae, staring angrily at her.

"Are you two the ones that have given Josiah and I these bodies?!" Marla cried quickly, interrupting them.

"Well, yea. No one on your primitive planet could do such a thing." Fos said, crossing her arms.

"Thank you." Marla sighed, letting her hand slide down the wall.

"What?!" Bae exclaimed in surprise.

"Thank you so much. This life with these new bodies is heaven. My love with him has given me the greatest feelings in the world and you are so kind for doing this for us." Marla said, taking a step back from the wall.

"We experimented on you! We did this for fun! You could've died!" Bae said striding towards the cell.

"Yes... but we didn't... and we're happy. So thank you. I'm sure if my sister were here, she would thank you as well." Marla told them.

"Good lord she means it." Bae said with wide eyes.

"Alright, I think it's time for you to sleep now. Sit down so you don't fall over." Fos sighed, clicking on the console. A quick sprits of sleeping gas and Marla, who had quickly sat down, slumped against the wall. They also shot a bit into Josiah's cell just to be sure.

"Are we ever going to let them keep their memories of us?" Bae asked, watching her sister work the console to erase the last few minutes from Marla.

"Not a chance. We'd be in so much trouble if anyone found out. No recollection or knowledge of us, you know the law." Fos said, shaking her head, "I'm going to change the cell configuration. We need a bigger one, not just a bunch of small ones.

The light barriers that made up the walls of the cell began to move, expanding and merging together. They grew into one large cell that surrounded both of their captives and left them plenty of room for equipment.

"So how will we begin? I mean, it doesn't really matter what we do at this point, she said it herself. This is heaven to them." Bae waved her hand about, "Let's go with your plan earlier. Start pumping milk from her and start feeding it to him. Then we'll let them get just close enough for her to suck him off, but let's keep him from cumming. We can see how big his balls will get."

"You are devious sister, but right. If she's really this happy knowing it's all an experiment, that means this next part will blow her mind." Fos chuckled, making sure to change the insides of the cell walls to an opaque white. They could see in, but Marla couldn't see out anymore.

"Did you get all of that IO? Get some pumps and things ready. Bind their limbs and hold them steady." Bae spoke to the ship.

"Acknowledged. Proceeding." IO said.

Chains of light appeared around their hands and feet.

"Pump in a little aphrodisiac." Fos hummed as she worked.

Josiah's cock grew erect in seconds and Marla's pussy grew visibly moist, dribbling between her thighs. Her nipples began to drip milk on her lap.

"Alright, wake up now." Fos said as a little more of another drug sprayed into the cell.

"Huh?! What?" Josiah jerked upright in a second, "What's going on? Where am I?"

"Whoa!" Marla sat up at the same time, her mind rushing forth.

"Marla? What's happening? I'm confused." Josiah asked as he looked around.

"I don't know... Oh god I'm horny. Josiah, let's do it! I don't care where we are, I need to fuck!" Marla moaned, feeling the full effects of her total arousal.

"I need to too!" Josiah groaned, feeling his huge erection. He shoved himself to his feet and found chains of white holograms holding him in place, "What? What the...? Come on!"

Marla got to her feet and found the same things holding her. She could take a step forward at most, still leaving almost three feet between the two of them. If they leaned forward, they might be able to kiss, but that the moment, fucking was out of the question.

"Oh come on! I need it!" Marla cried desperately, squirming and struggling to reach Josiah.

"Hey! Wait a second!" Josiah got an idea. He thrust his crotch out and his tentacle cock snapped forward, easily reaching Marla and sinking into her pussy.

Outside the cell, Fos groaned, "We forgot about the damn tentacle."

"Oh fuck it. Who cares. Just get pumping and stuffing." Bae waved it off.

"Yes! Josiah, that feels great!" Marla cried happily, feeling the tentacle burrow deeper and curl about in her pussy.

Just then, a trio of clear tubes descended from the ceiling, moving of their own volition. Two of them latched onto Marla's tits and began to pump. Creamy white milk immediately poured forth, rushing up the tubes. It came right back down the tube nearing Josiah and began to spill out on the ground.

Not wanting to see his love's glorious milk go to waste, he wrapped his lips around the pipe and drank her milk. The effect was immediate and powerful, his balls beginning to swell. His cock stretched out from his waist, growing in length and girth. Even his tentacle swelled in size, filling Marla more.
