Johnny Test Porn Story: “Pheromones”

Johnny, could you help me out for a second?” Susan’s voice vibrated on his wrist. It took him a moment to realize he was being spoken too. He looked down at the watch to see where she was calling from. The lab, obviously. He should have known she wanted him to test some nonsense.

 

 

“I’ll be there in a second, okay?” He pushed himself up off the tangle of sheets on his bed, pushing aside crumpled porno magazines and candy bar wrappers. He hopped onto the carpet and stepped over Dukey’s sleeping form.

 

 

As he left the room, he thought for a moment what it was like to still be a lab rat at fourteen. When he was eleven it was fun to travel around the town and fight the military and various trouble makers with his sisters and dog. Now, in the beginning of his High School years it was becoming stressful. Mutant farts were no longer attractive when you wanted to get laid.

 

 

He walked down the hallway, tracing the outline of the frames on the wall with runaway fingers. Finding himself at the lab door, he typed in the lab code without even thinking about it. The doors opened in the same fashion of the Enterprise and he walked in.

 

 

Susan was standing with her back to him, fiddling with a test tube filled with a liquid the same shining shade of sapphire as her eyes. Her deep red hair flowed down her back like velvet. Her lab coat seemed scandalously short and appealing, revealing luscious calves underneath her short blue flared skirt. “Hey Johnny,” his sister peeked at him over her shoulder, peering at him over her oval frames. She smiled at him gently.

 

 

Johnny looked around, his flaming hair catching the fluorescent light. “Where’s Mary?” he asked, cautiously, knowing very well that she might have been inside one of the many machines surrounding him in the metallic village. She turned towards him. Her shirt was a simple v-neck tee shirt, but it was tight and low cut. He couldn’t help but notice the generous amount of cleavage as it presented itself.

 

 

“She’s presenting plans for our new disintegrating weapon to the military right now. The proposal didn’t require both of us, so I figured I’d stay back and get some work done. You know, be productive?” Susan explicated. She removed her glasses and pulled a small cleaning rag from the breast pocket of her pristine lab coat. Susan cleaned her spectacles gently and replaced them on her nose, “But alas, I need your help.”

 

He sighed dejectedly without meaning to. “What do you want me to take?” he asked her. She looked at him, frowning slightly.

 

 

“No, no Johnny. I don’t need you to test something for me. I’m going to test it, but I want you to tell me if it works.” She explained, simply. He raised an eyebrow inquisitively. Why was he down here if she was going to test it?

 

 

He voiced the question, “Why am I down here then, Susan?”

 

 

“I’m not explaining this correctly,” she bit her sensuous lip, “Mary and I created a serum that increases the invisible scent of female pheromones. It’s supposed to make you absolutely irresistible to the opposite sex. Mary has ideas of making Gil lust after us.” Susan grinned at him devilishly. Johnny rolled his eyes; he was so tired of hearing about Gil. The blonde skater boy obviously had no interest in the two redhead scientists.

 

 

“Then why aren’t you testing this on Gil?”

 

 

“It’s only a prototype and I don’t want to test it on Gil yet.” Susan told him, “All you have to do is tell me if I become attractive to you. That’s all and then you can go back to your room to pupate. I’ll even give you twenty dollars.” She curled a stray piece of scarlet around her finger and tossed her hair over her shoulder.

 

 

Aw, what the hell. Why not? He nodded. Susan smiled excitedly and clapped her hands. She grabbed the vile and threw her head back, chugging the vile in an instant. She put the vile back and looked at him, wiping a small drip of blue from her lips. Johnny stared at her for a moment. Nothing was happening. It was obviously another one of their failures. He was going to tell her, “Susan, look it’s—”

 

 

He stopped speaking.

 

 

Something overtook him and he could not find any words. His blue eyes glazed over. “Johnny?” Susan tried to peer into his eyes, but he was looking at her through lust-shaded glasses. His cock sprang to attention. Suddenly, her hair seemed like a halo of crimson and her eyes were deep pools of azure. He could see her nipples peeking through the thin fabric. Was he drooling? He couldn’t tell. She said his name again but all he saw were thick, luscious lips.

 

 

He dove on her.

 

 

“J—Jo—” he cut her off with his lips on hers forcefully. He could feel her arms trying to push him off of her, but he was stronger. He pushed her back into the lab table, forcing her ass into the edge. She squealed from pain. He kissed her ferociously, licking her lower lip then forcing his tongue into her mouth. He drank her taste. She tried to bite him to force him out of her mouth, but he sighed with pleasure. His cock throbbed against his leg. Johnny winded his fingers around her cherry locks and bit her lips. She sobbed slightly, but an unmistakable sigh escaped her.

 

 

He broke the kiss and stared into her eyes momentarily. “Johnny, we can’t do this.” His sister’s eyes were wet with tears. She tried shove him away but he caught her hands and raised him above her head. Gently tipping her chin upwards with his fingers he bit her already purple lips. She screamed. “STOP! Johnny, why are you doing this?”

 

 

“It’s you’re experiment Susan. It’s always your mother fucking experiment, isn’t it?” Johnny said, nastily. He couldn’t hide his anger. Years of being embarrassed by her and Mary’s malfunctioning experiments… He was tired of it! “I’m always your lab rat, Susan! Always your little experiment. Well, how about you be my experiment now, huh Susan? How about that?” His cock was close to bursting now, but he managed to control his urges. He was going to take this nice and slow.

 

 

Susan was sobbing now. The tears dripping down her face were illuminated behind the lenses of her glasses. She looked absolutely beautiful. Like a crimson haired goddess dressed in white. Not for long. Johnny tore at her lab coat, opening it wider to reveal her tee shirt and short skirt. He wanted the lab coat on and nothing else. He looked around him.

 

 

Spotting a pair of scissors on the lab table, Johnny picked them up. Susan’s eyes widened in terror. He placed the scissors below her navel gently. “Stay still,” he whispered. Sliding them up expertly, the flimsy shirt shredded in half and two beautiful breasts popped out. He stopped to admire the silky ivory globes tipped in pink for a moment. He could hear Susan’s heavy breathing as he watched her well-endowed chest heave up and down. “Holy fuck…” he murmured. Johnny closed his eyes for a second and tried to regain control. He could smell something in the air and it was driving him crazy, making his manhood ache with need.

 

 

He opened his eyes again and went back to work, crouching down he positioned the scissors at the bottom of the navy skirt. Gently, taking as much care as he could possibly manage, Johnny cut up the skirt to Susan’s sumptuous waist. The tattered fabric fell to the ground to reveal a pair of mint green satin panties with a little bow. They were so cute he could have died. It was then that he realized what the smell was; looking upward at the crotch of the panties he saw a wet patch.

 

 

The smell driving him crazy was the scent of his own sister’s pussy.

 

 

He set the scissors aside on the ground and pushed his face into Susan’s clothed pussy. A choke escaped her. Even through the fabric Johnny could feel the drip of her arousal on his face. Instinctively, he nipped at her labia through the sheer satin. Above him he could feel his redheaded goddess’ legs going weak. He caught them for her, keeping her upright.

 

 

Susan leaned on the lab table for support as Johnny slid her cute panties to her knees, creating sweet, silky bondage and went to work gently spreading open the lips of his sister’s pussy. The soft floral smell enveloped him almost immediately. Intoxicating him like a hard drug. He was addicted to her scent. He could see the wetness gleaming at her hole and gently lapped it up like a kitten. She sighed with newfound pleasure as he explored her inner-walls. Tracing her petal lips with the tip of his tongue, Johnny nibbled and licked the clit gently. A little awkward with his inexperience, he didn’t quite hit the mark every time. But instead of directing him, the ever logical (and also virginal) Susan gyrated herself on his face to get more pleasurable access to his learning tongue.

 

 

Her orgasm hit like a ton of bricks. Incoherent in the throes of pleasure, Susan had proceeded to knock the pheromone test tube off the lab table and onto the floor. Eyeing it out of the corner of his eye, Johnny got an idea. Not stopping his tongue movements, he slyly inched his hand over to the ice cold test tube and grabbed it, suddenly shoving into her with force.

 

 

Susan contracted on the tube immediately without realizing, or caring, what the cold object contrasting with the heat of her little brother’s tongue might have been. Her moan rattled the beakers. A soft splash of juices coated Johnny’s face and mouth as her orgasm gently subsided with a few last clenches.

 

 

Pulling the slippery test tube out of her and setting it aside, Johnny stood up to face her. Susan blushed intensely and could not look him in the eye. “Better than Gil?” he said spitefully, knowing full well that she had never been with the blonde. Susan frowned and looked away. Johnny smiled evilly and began undoing his pants.

 

 

At the snap of the belt buckle Susan looked up at him. Her eyes once again widened in surprise as she watched him take off his pants and boxers. His hard cock popped out, standing at full attention. A small, shining string of precum dripped from the end. “J—Johnny what do you think you’re doing?! You’re crazy if you think I—” he didn’t let her finish.

 

 

“I think you’re going to let me do whatever I want. You just let your little brother make you cum and I know you have fucking security cameras in this place. Do you want Mom and Dad seeing what you made poor little Johnny do with you most recent experiment?” he asked innocently, unable to keep the malevolence out of his voice.

 

 

“Johnny I don’t understand why you’re doing this…” Susan protested, “I’m sorry for all the years as a lab rat I won’t do it anymore. Let me make a pheromone antidote. Please.”

 

 

“No,” Johnny said angrily, “It’s more than that. It’s everything I’ve done for you and you still see me as a little goddamned kid. I’m not a child anymore Susan. You can’t see me as anything other than your little brother.” He sounded hurt and he knew it. Things he didn’t even know he thought were escaping from him. Was it the pheromones talking? No, it was him… maybe he was always in love with Susan and just needed a reason to act on the feelings. Really, how many hundreds of pictures of porn models with straight red hair and glasses did he have upstairs?

 

 

Susan looked at him gently, her deep cerulean eyes magnified ten-fold by the lenses of her oval glasses. So fucking beautiful. No more time for talk, he may never have another experiment to blame for something like this again and he wasn’t going to waste it!

 

 

Before she knew what was happening he took the two steps between them and was on top of her. The thin fabric of his shirt pressed against her bare breasts. His cock rubbed the soft tuft of crimson above her pussy. He kissed her deeply, tenderly. He took his time on each kiss, taking in the soft feel of her lips and the gentle roll of her tongue and before he could comprehend her actions, she was kissing back. He tugged her closer and made the kiss deeper, deeper, until…

 

 

He couldn’t take it anymore.

 

 

The heat off of her pussy was coating his cock in moist warmth. It was driving him absolutely insane. Without warning he broke the kiss and moved his hands down her body, laying soft scratches down her navel. She winced slightly, but sighed. He slid her panties off one leg and spread her legs open. She muttered some unheard protests as he positioned his quivering length at her entrance. In one fell swoop he drove into her.

 

 

She clutched her eyes closed in pain. He waited a moment until she opened them again to move. He sighed, burying himself in her neck and enveloping himself in her hair as he fucked her. Her pussy was so sweet and lush. It was soft like satin and smooth as butter he thought he might come from just a few strokes.

 

 

The tightness was unbelievable. He bit her neck as he increased the pace, using his hands to grip her buttocks he picked her up and positioned on the very edge of the lab table so that he could drive into her more effectively. Johnny could feel his sister’s nails dig into his buttocks as she clenched down on his hardness. She moved forward, impaling herself on the length. Any protests she may have had were long forgotten.

 

 

Her sticky cum dribbled down his cock into his pubic hair. He could hear the arousing slap of skin on skin each time their bodies smashed together in motion.

 

 

Susan’s muffled cries alerted him to her. He shook his head from her flowing hair to look in her eyes. She was sobbing too hard to speak, a choked look of shame and unrestrained lust tore her face in half. It was as if he could see her inner-turmoil painted like a mural in her endless eyes. She bit her lip so forcefully one of the bruises he’d left welled back into shining life. It was as if all movement had stopped, though he knew he was still thrusting into her.

 

 

Wordlessly, he licked away her tears. They tasted salty, of lust and desire. Of need and fulfillment. Of the present and the future. Kissing her purpled lips with the utmost tenderness, he felt his heart swell. The problem being, it was not only his heart swelling. He gripped her ass tightly and breaking the kiss he whispered, “Sorry for this,”

 

 

Susan didn’t get a chance to open her mouth before Johnny pulled out of her and flipped her around. She caught herself on the lab table and it wasn’t long before she felt the swollen head of her brother’s penis at the puckered rosebud of her anus. “Johnny, oh God no… please stop! Please!” she begged uselessly. The scientific fact was: she couldn’t deny that she was still very wet and the lubricant that her brother was using was her own. The fact was, she had read many magazines where the phrase “No” really meant “Yes” and by this point she wasn’t really sure if this was one of those situations or not. She couldn’t finish her thoughts as her loudest scream yet escaped her.

 

 

Her tears ran anew as Johnny’s pubescent cock probed her innermost walls with little forgiveness. She could feel herself stretch and rip in ways she’d never truly thought possible and yet… she didn’t want it to stop.

 

 

She could feel Johnny’s cock swelling inside her with each stroke, reveling in her tightness. He appreciated her, didn’t he? He found her body beautiful and desirable; she could deduce that from the way he was digging his nails into her hips as he grinded into her. So what if he just so happened to be related to her? Susan didn’t care, anything that felt like this couldn’t be wrong.

 

 

One of Johnny’s hands snaked around Susan’s waist to her clit, tickling it gently. A moan escaped her and she clenched without meaning to, eliciting a guttural noise from deep within Johnny. Her brother was becoming animalistic as he neared orgasm. Any signs of gentleness gone, he pounded into her completely on instinct and feeling.

 

 

Susan gripped the lab table white-knuckled, she could feel his nails draw blood as he pummeled her asshole mercilessly. His fingers bruised her clit from the force of their strokes, causing her honeyed wetness to run down her legs with her excitement. Their movements knocked beakers and stands down. Pencils and papers clattered to the floor around them. Susan’s breath began to escape in staccato as she neared her second orgasm when Johnny gave her a hard, vampiric bite on the back of her neck.

 

 

Her entire body tightened.

 

 

It was that final spasm that sent Johnny Test over the edge into the land of no return. He felt his balls clench as his sperm began to release itself he pulled out of Susan and came on the ivory globes of her ass.

 

 

Staring at Susan’s heaving form, scratched, sticky, with a cum covered ass, something seemed missing. He realized it was his mark. If he could never have the pleasure of doing this again, he wanted her to have something to remind her of this day. Quickly, he gripped Susan’s waist and forcefully issued a few, well-placed smacks to each cheek in turn. A surprised squeal escaped her.

 

 

He admired the cum hand prints for a moment before releasing her. Susan let go of the table and stumbled sideways for a moment, before her legs gave out from underneath her.

 

 

“Oh my God Susan, are you okay?” he dove to the floor and lifted her head up. Seating himself on the floor, he put her head in his lap.

 

 

She blinked at him, “I’ve read about this,” she said, “it’s a type of weakness one gets after a very strong orgasm. The normal symptoms are usually wobbling legs and slight dizziness.” Johnny couldn’t help but crack a smile.

 

 

“Susan, I’m sorry,” Johnny apologized, he could feel himself tearing a little. Now that it was over, he knew that he had pretty much raped his sister. “It was… I mean, the pheromones. You know? I am really sorry about all this,” he repeated.

 

 

“Johnny?”

 

 

“Yeah?

 

 

Susan was silent for a moment before sitting up. She sat on his lap, facing him. He could still feel the latent wetness of her pussy on his semi-hard cock. “Pheromones just increase your attraction for someone you’re already attracted too. They don’t just materialize attraction,” she smiled, “Plus, if you recall I was never using them in the first place.”

 

 

Johnny matched her smile. Susan’s fingers danced playfully across the tips of his flame-shaded hair. She kissed his lips, letting him guide his tongue into her mouth. His hands massaged her breasts, pinching her nipples. She squealed. Susan was quickly finding that she was quite the aficionado of the pain/pleasure mix.

 

 

Susan raised herself up on her knees while her brother straightened his cock. She gently lowered herself onto it. Johnny gave her a pleased sound and she matched his grin. “What now?” he asked.

 

 

“Bite me.” She grinned, leaning her head to the side and exposing her neck.

 

 

He smiled.
