Species Experiment - Sol III

"Don't be scared. It'll feel good. Trust me." He whispered sensually in her ear and he thrust his pelvis forward. His cock pierced her hymen and she screamed, arching her back. The orgasm that exploded through her was the greatest relief she had ever known. Her pussy clenched and her eyes rolled back in her head.

"Ohhh so good~!!" She cried, reeling from the extreme feelings flooding her mind, "It feels like your arm is inside me!"

He barely had three inches in her and it already felt amazing for both of them. Kyle remembered what it was like with his last girlfriend two years ago before he met Tammy. It wasn't anywhere near this good.

Tammy on the other hand was panting and having trouble even forming a coherent thought. Even through the twinging pain of her torn hymen, pleasure was totally overwhelming her mind and soul. She gasped and shuddered as Kyle's cock sank a few more inches into her. Half his cock was inside her and she already felt like he was slipping up to her throat. He could feel his head pushing against her cervix and he pulled back to thrust again. She cried out loudly and he sank a little bit deeper than before.

"Kyle! Kyle, yes! Yes~!" Tammy howled, feeling another orgasm creeping up on her.

"Tammy, you feel so good inside!" Kyle groaned, pulling on her hips as he pushed harder. Her insides seemed to stretch a little and he felt her cervix start to give. She moaned and hugged him tighter, another orgasm erupting through her entire body. He slipped through her stretchy cervix and his head popped into her womb. The sensation of such a deep penetration coupled with her orgasm made her scream at the top of her lungs.

While her wet insides were convulsing around him, Kyle pushed the last bit of his cock inside her. It felt so astounding to have the entirety of his shaft buried inside her delicious warmth. He moaned in ecstasy and came. His muscles clenched and...

Nothing.

Nothing happened at all. His dick twitched and nothing came out. He thrust again and gave a loud moan. It felt great, but he just couldn't get anything to come out. His balls tingled and he felt them stretch a bit. He groaned loudly and pulled out of her.

"Ahhh... Kyle... that was amazing... but why didn't you... impregnate me?" Tammy panted, letting go of him.

"I don't know. It didn't come out. This has never happened before." Kyle said, touching his balls nervously, "But these got bigger. I don't know why."

"Well maybe I could try... you know... my mouth." Tammy said with a sheepish embarrassment.

"Sure. If you want." Kyle nodded and she tried to sit up. Her body didn't want to listen and she barely got her shoulders off the bed.

"I can't get up. I can't feel anything... down there." Tammy mumbled, smiling a little.

"Here, just lie back. If you really want to do this, I'll just take care of it." Kyle said, helping her lay more comfortably among the pillows. He moved up until he was straddling her chest. His cock lay on her night gown, between her breasts. She blushed as his wet dick pushed against her nose.

"Can you expose my breasts?" Tammy asked, her face turning crimson as she felt the heat coming off him.

He smiled happily and pulled down the shoulders of her nightgown. He pulled it down past her boobs and they jiggled free.

"I've heard... I've heard that... you can do pleasurable things with my breasts like this while I..." She looked down at his dick. He smiled and grabbed her ample bosoms, pushing them against his dick. Her lips wrapped around him and she sucked on the head of his cock. Her cunt clenched with pleasure as she tasted the sexual fluids all over him. She could feel his big balls pushing against her chest and the heat between her boobs.

He moaned happily as her tongue wriggled about under his cock. It felt ecstatic and he couldn't resist humping a little. Her eyes went wide as he pushed to the back of her throat. He rubbed her beautiful mounds back and forth as he humped. The orgasm came on wonderfully fast and he grunted loudly. He came and thrust into her mouth. She gagged and coughed.

Again, nothing came out and again, his balls stretched a little more. They were nearing the size of oranges and he groaned loudly.

"Nothing. Ohhh damn it." Kyle moaned in annoyance, sliding back from her, "That felt so great, but nothing."

"This sucks." Tammy sighed, licking her lips as she let her head fall back on the pillows.

"How do you think I feel?" Kyle sighed, rubbing his balls with both hands, "I need to go to the doctor."

"Right now?" She pushed herself up on her elbows.

"No, I think I can wait until morning. I'd rather cuddle with you sweetheart." Kyle sighed, slumping into bed next to her. His dick flopped against her naked thigh and she squeaked a little.

"I can't believe we just did this." Tammy mumbled, sighing softly.

"I'm going to love you forever." Kyle said, turning to her. She was pulling her nightgown off completely. She kicked it away and turned over, letting him cuddle close around her. His dick pressed against her bare ass and she blushed, heart continuing to pound.

"Those aliens... you think they made it feel this amazing? I always heard it was supposed to hurt the first time. And... and you were inside my... womb." She murmured quietly.

"Yea, that's not normal. But it felt so good, huh?" He whispered, wrapping his arms tightly around her.

"I love you so much." Tammy cooed.

*******

It had been the best night sleep of their entire lives. Their sweaty, warm, naked skin pressed together all night had made everything so incredibly sensual. He had awoken to a raging, hard cock pressed lustfully between Tammy's soft buttcheeks.

He squeezed her and gently rubbed his cock back and forth.

"Mmmm... you're so big..." Tammy said quietly, feeling his hard, burning hot length rubbing against her butt.

"I want to be inside you." He whispered to her and he shuffled down to get his dick between her thighs. He pushed upward and felt a warm hole. He knew it wasn't the right one, but he wanted to see what Tammy would do. He pushed and her ass began to stretch around his dick.

"H... Hey! That's... that's not my..." Tammy squeaked as he pushed.

"Sorry." He said, slowly pulling back.

"No! It... it felt... good. So if you want to..." Tammy mumbled, her face burning.

"Really? Just tell me if you want to stop." Kyle said with a wide smile. He grasped one of her breasts and pushed, sliding his cock into her ass. She moaned loudly and he felt a strange wetness growing around his dick, as if her ass was getting moist just like her pussy would. He slipped deeper, sliding with ease.

"Ohhhh~! Kyle!" Tammy moaned, feeling just how deep his erection was creeping.

He buried his entire length inside her, almost a whole foot sunk into her backside. She moaned and rubbed her face against the pillows, her ass stretched and full of hard cock.

"Oh god this feels good." He moaned, thrusting harder. His balls slapped against her thighs and she moaned louder.

"Kyle! I'm gonna cum Kyle!" She cried out, her ass clenching tightly around him.

He groaned as he felt his balls shudder. They began to stretch again as his orgasm was backed up yet again. He moaned and grunted frustration.

"I forgot about that." Tammy sighed, rubbing her head.

"Yea, I need to go to the doctor today." He sighed, feeling his balls tingle further.

*******

After a meeting with his doctor, Kyle and been told that he needed to go to a specialist at the urologist's office. It was annoying to hear because his balls had continued to get bigger even after he got out of bed. He had come down hear wearing sweatpants and they were just about stretched to their breaking point. He headed inside and talked with the secretary. She directed him to an examination room to wait for one doctor Sugimoto. After seeing what the secretary had looked like, he wasn't looking forward dropping his pants and letting her fondle his now basketball sized testicles. He couldn't help but feel nervous as he looked around. In the room, there was only one chair and it had arm and leg straps on it. In front of it was a large three foot stainless steel tub. He looked around before sitting down in the chair.

Down the hall, doctor Sugimoto was looking at her patient chart. She smiled widely at the next one on the list. Another man with backed up testicles. She loved her job when it came to these. You see, she the cum fetish to end all cum fetishes. She liked to smell it, taste it, see it spew from cocks. She liked to feel it on her skin, liked to feel it filling her wholes and she loved to bathe in it. A good bukkake was nothing short of heaven to her and the changes brought about by the recent alien virus had made her ever happier.

She headed into the exam room and looked at Kyle. His grey sweatpants were stretched wide around his gigantic balls and she almost moaned at the sight of them. These were the biggest yet and she knew how this virus made men cum. This man would be able to fill her tub and give her all that she wanted.

"Hello Kyle. So I was told you were having a little issue with getting to release. It seems to be a common problem lately. I've gotten probably thirty cases since the aliens started all this. We've determined that the change in genitals and increase in sensitivity causes a spasm that restricts seminal flow." Doctor Sugimoto explained professionally.

Kyle barely heard anything she said, as he was entirely too busy staring at her enormous breasts. Her shirt was clearly too small and she was almost busting out of it. The mutation had clearly hit her hard, almost as hard as his dick was getting.

"So what I'm going to do is give you a shot at the base of your penis and strap you to this chair. It will be uncomfortable, but it's very important that you don't move while the spasm releases. Your testicles will immediately attempt to return to their normal size and you can imagine exactly how they're going to do that, thus the tub. Now, please take off your pants and sit down in the chair." Sugimoto instructed him.

"Ye... yes ma'am." He stammered, still staring at her. He pulled on the pants until the waistband started to pop and break before he could finally get it over his enormous balls. He dropped them and waddled over to the chair, grateful to be allowed to let himself free of those sweats. His cock hung out more than a foot from his crotch, easily clearing the edge of the chair.

"Good, we won't need to put on a hose to get your cum into the tub. Now, your orgasm is going to be almost immediate once the spasm is released, but the spasm itself is going to take some time to loosen up. During that time, you will start to release large amounts of precum because of the way the drug acts. So please try to sit still because we'd like to keep the office clean." Sugimoto said, "Oh! Speaking of which, would you like to take off your shirt and shoes? I can store them in the cupboard here so they'll stay dry."

"Oh, yes please." He nodded, stripping off his shirt. Sugimoto quickly stored them and moved to strap his arms to the chair. She strapped down his legs and then touched his cock, making sure it was properly in position over the tub. She wanted every bit she could to have fun with after this.

"Okay, now this first part obviously isn't going to feel good, but you're going to be very thankful for it." Sugimoto said, casually pulling off her coat and then her top.

"Uhhh..." He started, his dick twitching excitedly.

"Oh, I don't want my clothes to get ruined either. I need to stay in here the entire time to make sure the drug acts as it should and no complications set it. However, during that time, I expect you'll try to make a mess of me." Sugimoto said with a giggle as she dropped her skirt and panties.

She put all the clothes away down on the bottom shelf of one of the lower cabinets. Kyle watched her bend all the way over and show him her delicious, wet slit. His dick was aching to unload and his balls shuddered with new growth.

"We better get started." She said, holding up a small needle, "Hold still."

She lifted his cock and he felt a twinge of pain. Almost as soon as she had thrown the needle away, his dick began to drool thick precum. It dribbled in long ropes and pooled in the tub.

"Perfect, that's just right. Is that feeling better?" She asked, teasing her fingers through the stream of glistening delight.

"Ohhh yea, I can feel it already." He sighed. Even with the relief of something finally coming out, the ache to orgasm was getting ever worse.

"Alright, now we just have to wait a little while." She smiled, pulling over a small stool to sit down. She sat across from the tub, watching his cock intently. He couldn't help but blush a little with the intensity at which she was staring at his genitals.

One minute passed. More than a pint of pre was lying in the bottom of the tub. Two minutes, then three and a full gallon was seeping into it.

"You're getting there, how does it feel?" Sugimoto asked.

"I need to cum. Please, can't you give me more of that stuff? I want to cum!" He groaned, pulling at the arm straps.

"No, that would be dangerous. I told you that this would take some time. You've released probably close to two gallons of pre so far. Here, let me see if this helps." She said, leaning across to him. Her hand grabbed around his cock and he grunted loudly from pleasure. A huge eruption splattered across her breasts and up her shoulders. He moaned happily and she laughed, "Well there's something!"

She stepped back and put her hands on her breasts, rubbing around the sticky goo. Her huge boobs were shining with it and he watched it stick in thick strands in her cleavage.

"Alright, let's try to get a little more out." She said, stepping into the tub. She knelt down in the inch of sticky goo and held her tongue under the constant stream. As it ran down her cheeks, she put her mouth on his head. It jerked and a huge spurt filled her mouth. She gave a throaty moan as she swallowed it down.

"Ohhh yea! I can feel it coming! This feels so much better!" He moaned as she pulled on him with both hands, "Oh yes! Yes! Ahhhhh!"

Thick, hot semen exploded from his cock with the force of a firehose. It glazed her face and ran down her front, spewing thick and rich. The scent overwhelmed her and her pussy grew wetter and wetter. She jerked on him and he unleashed more all over her. She let go and leaned back as his shaft jerked around. It sprayed sticky seed all over her waiting body. She loved every second of it, loved every drip of goo that fell on her body. She rubbed her breasts and slid her hands down her belly. She massaged herself all the way down to her thighs, rubbing the hot goop all around.

"This feels so great!" He moaned happily.

"Go on, keep cumming. You're doing fine." She moaned, starting to finger herself as he came on her chest more. The tub was about half full now, probably a thick six inches of spunk.

His balls were inching up the chair and tingling happily with their lessened weight. This continued for probably the next five whole minutes, his entire body shuddering in orgasmic pleasure. The tub neared over-flowing as his sack completely returned back to normal. He slumped in the chair, panting happily with how much better he felt. His cock slowly fell limp on the wet chair between his cum-lathered thighs.

"Thank you..." He sighed, lying completely still.

"Ahhh... No, thank you." Sugimoto moaned happily as she fingered herself amid all the cum.

Kyle couldn't help but watch as the totally iced woman cooed and shuddered with pleasure. She rubbed the cum all over, constantly bringing her fingers to her lips to drink more and more of it. Her finger teased her clit wildly and she felt her biggest orgasm yet rushing up on her. She shuddered and cried out, thrashing about in all the slime.

"Yes~!" She cried, collapsing onto her ass. The cum rose up and ran over the sides of the tub, dripping all over the floor. Kyle sat upright and rubbed his face, a little exhausted from it all.

"Doctor, I... I don't rightly understand, but thank you." Kyle sighed, "Because of you, I'm now going to go home and make a baby with my beautiful wife."

"Y... Yea... good luck... with that." She sighed weakly, staring at the ceiling.

*******

Kyle walked through the door and sighed happily. It had taken him a while to get cleaned up at the doctor's office, and he felt so much better to get back home.

"Sweetheart! Are you home?" Kyle called out.

"In here!" Her voice came from the bathroom.

He kicked off his pants, lost his shirt and waltzed into the bathroom naked. She was standing in front of the mirror, looking closely at her nose. He walked up behind her and put his arms around her, pressing his half-erect cock to her ass.

"Dear... I want to do it... Right now." Kyle whispered in her ear, "I want to have a baby with you."

"Eeep~!" She squeaked in surprise, looking up at him in the mirror.

He grasped her breasts through her shirt and rubbed himself against her. She squeaked and tried to push his hands away.

"But... But Kyle... Last night... we really shouldn't have. We're not married." Tammy stammered, "I... I cracked under my desire..."

"Look, we both know that we can't wait. We won't make it to the end of the week." Kyle cooed, groping both of her breasts more. She moaned and shivered.

"Nooo~!" She gasped.

"I want to fuck you again. I want to put it in your delicious little pussy and..." He licked up the back of her earlobe, "...Fill you up with my hot seed."

"Ahhh!" Tammy moaned loudly, pleasure exploding through her at just his words.

"Okay, fine. I'll be in the bedroom with this thick... hard... cock. Come if you want to." He teased her, rubbing his erection against her ass.

He turned and stepped away from her. He didn't even make it to the door before Tammy threw her arms around him and grabbed his hot dick. She pressed her breasts against him and felt up and down his shaft.

"Fine. Fine, Kyle. I want it bad. I want you, I'm dying for you!" She moaned, stroking up and down him.

He turned around and scooped her up in his arms. He took her back to the bedroom and tossed her on the bed with a funny squeak from her. Before she could move, he grabbed her and ripped her clothes off. With the light of day shining through the window, they could see each other's naked bodies completely. Tammy blushed and looked away as he spread her legs. Her pussy was undeniably wet and he nestled his tip against her.

"Hey sweetheart, let me tell you a secret." Kyle cooed, kissing her on the lips passionately, "It's not wrong to enjoy it with your lover."

There was still a slight bit of shame on her face as he looked her in the eyes. He watched her intently and pierced her womanhood with a single thrust. Her face went from blushing to pleasurable shock in an instant. She moaned and threw her head back, her heart clenching with all the sensations rushing up from her pelvis.

"Kyle, yes!" She cried loudly, arching her back. He penetrated deep into her, pushing right up against the deepest parts of her.

"Ohhh you feel so good!" Kyle grunted, thrusting in and out of her tight slit. His balls had retained a touch of their increased size, probably the size of plums now. He gripped her hips and shoved harder.

"You're so big! You're splitting me in two!" She cried desperately, her body already nearing orgasm.

"I want to cum inside you! I want to fill you to bursting!" He moaned as he humped.

"Do it! Fill me! I want your child!" Tammy howled.

He drove himself into her and unleashed his orgasm. Wonderful pleasure erupted through him as his cum poured into her womb. She cried joyously as her insides stretched from the spunk. It felt so good to feel the warmth growing inside her. He thrust again and sent her over the edge of a wonderful orgasm.
