Dirty Erotic Oneshots by Mistress_ Red (reading list .txt) 📕

Jenna decided to focus on her work. She was a little behind on her actual work assignments having gotten carried away with her own private research. She unlocked her office door and sat down to finish off two reports. The work helped to keep her mind away from her body's lustful cries but the heat emanating from her loins kept sexual thoughts perpetually playing in the back of her mind.

Just as she was getting finished off one report and was about to check on her bodily readings, Jake Watson walked in. Jake was the Chief Executive Officer of SimBioTech. A chemist by training, he had devoted many years of his life to research in Universities and had finally moved into the more lucrative area of private funded research. At 56, he was extremely distinguished looking and still had a trim figure.

"Hows it coming along Jen?" he asked "Pretty good Jake." Jenna replied, "almost finished off the Digestive Probiotics research." "You look kind off flushed." Jake said with concern. "Are you alright?" "Y-Yes." Jenna responded, a little too quickly she realised. "Everything's fine."

Jenna realised that each time she looked at Jake, her breasts started to tingle. Suddenly her back seemed to arch and her hips jerked outwards. Jenna made a conscious effort to control her spasms. Then it happened again, as if she was thrusting her hips in a dance.

Jake was explaining something to Jenna but her mind was too focused on controlling her spasming legs. She realised that each time she looked at Jake, one of her legs spasmed. To make it worse, the tingles had spread from her breasts to her pussy.

She also noticed that her sense of smell seemed to have become extremely acute. Jake's cologne teased her nostrils and she could even smell his musky sweat. The hot flushes seemed to envelope every inch of her body and all her senses seemed to be heightened.

"You smell good." She heard herself say. Her back and hips were spasming even more now and she was surprised Jake didn't seem to notice. She could smell herself too. The whole room seemed to smell of her sexual juices.

"Uh..Thanks, I suppose." Jake said, confused at this sudden compliment from Jenna. "Is something wrong Jenna?"

"N-no... I mean.... No" Jenna muttered. Her mind had become cloudy, filled with a desire that she could no longer control. Her body was craving fulfilment although her mind was telling her that she couldn't do anything. Not here. Not with Jake.

"Jenna?" Jake had come forward and had placed his hands on Jenna's shoulders. "What's wrong? Your hips seem to be twitching. Is everything okay?"

"Uh.. yes... I mean no. Oh God you wouldn't understand." Jenna cried, trying desperately to control her feelings. Her body was slowly taking control over her mind. 

"Tell me. Maybe I can help" Jake said, still confused. Jenna buried her head in Jake's shoulder, her arms clutching his tightly.

"This stays between us." Jenna hissed. Her body had taken over now. She needed it and she needed it now. She needed to be fucked.

"Yes, of course" Jake replied. "What is it? What's wrong?"

"Fuck me. Fuck me now. Don't ask questions, just fuck me!" Jenna pleaded. At the back of her mind she knew this was wrong and that she shouldn't be doing this. Not here and most certainly not with Jake but she couldn't help it. 

Jake was not one to ask questions when given the opportunity like this. He had spent many days secretly checking Jenna out and fantasising about her. Yet, he would never make a pass at her or do anything to jeopardise their relationship. But her asking him to fuck her, in fact almost pleading to be fucked was a different thing altogether!

He unzipped his pants slowly as Jenna cleared the table with one sweep. She unbuttoned her blouse and lay on the table. Jake took in a deep breath as he saw how erect and long her nipples were. Raising her hips, she pulled her skirt and panties down in one smooth move.

Jake had removed his pants now and his cock was stiff at attention. He leant over to lift her legs and Jenna helped by spreading them. He looked at her red swollen pussy and let out a low grown.

"My God! Look at how swollen you are!" Jake cried out. "and your soaking....!"

"Just fuck me Jake. Please! I need it." Jenna pleaded.

Jake slid his cock slowly into her hot seething pussy. He had never felt anything so tight before! Although she was so well lubricated, her pussy was tight and hot.

A hot, wet, tight cunt! Jenna hissed as she felt his cock spear its way slowly into her. She could feel every inch of his cock separating her swollen pussy walls. It was pure pleasure as she felt his hairy balls finally smack against her vulva.

"Fuck me Jake. Fuck me hard." Jenna moaned. "Don't be gentle with me. Just fuck me!"

Jake needed no further prompting. He grabbed her shoulders as Jenna wrapped her legs around his ass. He started thrusting deep and hard into her, knocking the breath out of her with each thrust. Jenna moved her hands upward to remove Jakes hands from her shoulders. She placed them on her breasts, urging him to squeeze them as he fucked her.

His hands covered her breasts and he squeezed them. He pinched her nipples hard, eliciting a sharp cry from her. He grabbed her breasts and used them as leverage as he sawed in and out of her pussy.

Jenna's mouth was wide open in an 'O' as Jake hammered hard into her. She drummed her heels into his ass, urging him deeper and deeper into her.

"Aaooooohhh....yesss...yessss....fuck me! Fuck me! Fuck me hard!!" She cried out. All sensation was focused in her battered cunt and her whole body felt like it was nothing but a big, pussy with a thick cock satisfying it.

"Cummm...gonna cummm....cum with me...please....cummm!!" Jenna mewled, almost incoherently.

Jake could feel the spunk building up in his balls and he thrust harder into the beautiful girl lying like a whore under him. 

"Unnh...gonna cummm" Jake cried out.

"Fill me! Fuck me and full me with your cum" Jenna wailed. "Fill me like the bitch I am!"

Her gutter mouth was all it took to drive Jake over the edge. He slammed into her and his cock throbbed and spasmed as he shot his load into her.

"Oooohhhh Yeaaaahhh...yessss...." Jenna cried out as her own body spasmed and shuddered with ecstasy. She felt her pussy clamp down on Jakes cock, milking every last drop into her boiling pussy. Her pussy seemed to clamp and spasm many times, leading her to another mini orgasm.

Jake stayed deep within her until her pussy stopped clenching and he slowly withdrew his cock. He looked down at her pussy hair all matted with both their juices.

"That was so hot Babe!" Jake enthused.

Jenna smiled weakly up at Jake. "Thank you. You don't know how much I needed that." One hand moved automatically to cover her leaking pussy while she draped her arm ove her breasts. The attempt at modesty didn't go unnoticed and Jake averted his eyes as he pulled on his pants.

As is often the case after hot, unplanned sex, reality set in and Jake started to wonder what had really caused this sudden sexual wantonness from Jenna.

"Um..Jenn? What exactly just happened?" Jake asked tentatively. "W-Why did you need it so bad?"

"Shhh!" Jenna replied. "Please. No questions and please keep this between ourselves. Someday I hope to be able to explain all this. For now, please just consider it a favour among friends. Okay?"

"Um, yeah. Okay." Jake responded. " I suppose it's the least I can do. Um..call me again if you need help." He continued lamely, trying to make a feeble joke. "Anyway, I suppose I should get going."

Jake paused at the door to turn back and feast his eyes once again on the nubile figure lying on the table. Jenna didn't respond as she watched her boss walking out of the lab. She pictured what a sight she must make, lying with nothing but her blouse hanging open off her, with her cunt dripping cum.

She reached backwards for some cotton swabs and cleaned herself up before swinging off the table and heading into the toilet. She was thankful that each lab had a private toilet and she was able to fully clean herself up without leaving the confines of her lab.

After cleaning herself up she made more notes, adding in her heightened smell and spasming back and hips. That made seven side effects. And of course her increased sex drive – but that was the main purpose of the experiment!

Jenna consulted her research again, poring over her notes. She finally found it. Her spasms of the back and hips were a signal trait known as the Lordosis Behaviour. It caused the spine to arch downwards, making the genitalia elevated and more easily accessible. Obviously the experiment was working. She was displaying all the traits of estrus. 

She recalled the careful study that she had done. How she had carefully extracted the blood of cats and dogs and then spun them in a centrifuge. This had enabled her to isolate and then combine the enzymes that she required. After controlled tests with lab rats and special computerised simulations she had injected herself with it. And now the results were proving spectacular. 

She was a bitch in heat!

She made a mental note to fuck on her fours the next time, since she was displaying acute signs of Lordosis. She imagined herself on her fours, her hips pressing themselves downwards involuntarily, awaiting a cock to take her from behind.

Jenna felt a gnawing in her stomach as she thought about getting fucked again. She had really enjoyed the fuck with Jake. The enzymes had altered her physiology to make it the most sensational fuck she had ever received. Even though she was still feeling horny, she knew she had to see how much she could control herself.

Perhaps she had injected herself with too strong a dose. Briefly she considered taking the antidote. But if she did, she would never know how far she would go and how to perfect her experiment into a drug. A drug that would make her millions!

She had only one concern. Estrus, or the condition of a bitch in heat, lasted anything from 4 days up to 15 days!! If she was so horny on the first day of the Estrus Cycle, could she last for 4 days? And what if it went up to 15 days? She knew however that she had to see the experiment through. She was a bitch in heat
