WICKed Hormones Ch. 09

Jacob overheard his aunt's statement and curiously wondered what dark secret the two sisters shared. He was interested in finding out, but that could wait for another day. For now, his only concern was that one of these two gorgeous women was going to help finish him off. Heck... a threesome would be even better... that would be like hitting the jackpot.

After the sisters ended their embrace, Brenda turned back to Jacob and said with a smile, "Now... I think I should finish my special treatment for my special patient."

Karen grabbed Brenda's forearm, and they locked eyes. The older sister then said, "You know you don't have to do this."

Brenda glanced back over to find Jacob standing by the exam table, patiently waiting and slowly stroking his massive cock. "What kind of physician would I be if I didn't follow through and help my patient?" She then looked to Karen and added, "Besides, he's also my godson... so as his godmother, I think it only proper that I help him if I can."

"Well, if you insist..." Karen then alerted her sister, "However, I feel I should caution you... it tends to make quite a mess."

Giggling, Brenda pointed down at the beaker in Karen's hand. "That's what this is for." She then motioned with her head towards Jacob, "Stud over here already warned me."

Karen added, "I should also inform you if his stuff gets on your clothes... the stains won't come out." The embarrassed mother blushed and continued, "I've had to throw away several good blouses."

Brenda's eyes widened as she replied, "Ohhhh... I see what you're saying." The horny physician reached back and began to unzip her short skirt. She then looked over to Jacob and said, "I really like this outfit, Jake, so I hope you don't mind if I take it off."

The excited teenager shook his head and replied emphatically, "No, Aunt Brenda... I don't mind one bit!!" Jacob's excitement increased as he watched his aunt shimmy the tight skirt down over her wide and curvy hips.

After Brenda stepped out of her skirt, she turned and placed the garment on the exam table. Jacob's eyes went wide with astonishment as he gazed upon his aunt's beautiful backside. Her skimpy thong panties left her round and juicy ass nearly naked.

Dr. Sullivan then unbuttoned and slipped her blouse from her delicate shoulders. Brenda was now down to her lacy bra, skimpy panties, thigh-high stockings, and heels. The respected physician and wife looked as if she had just stepped out of a lingerie catalog.

Jacob watched with anticipation as the walking wet dream he knew as Aunt Brenda stepped back over to the rolling stool. His eyes drank in the sight of her mostly naked body with its lightly tanned skin and ridiculous curves.

Brenda sat back down on the stool, making her enormous tits jiggle around inside the white lacy bra. She then reached behind her back and began to unfasten the hooks on her bra and said softly, "I just bought this the other day... I don't want to mess it up."

From the chair across the room, Karen asked, "What about Mark... are you going to be okay hiding this from him?"

Brenda looked back over her shoulder at her sister and replied, "Don't worry, Sis... I'm a big believer in doctor/patient confidentiality. Besides, it's not like we're doing anything really bad like having intercourse."

Karen couldn't help but feel her cheeks burn from embarrassment. She looked down, hoping her sister did not see her blush as that could give her away.

Brenda removed her bra after releasing the final hook, exposing the big wobbling breasts to her teenaged nephew. "Wow... nice ones, Aunt Brenda!" Jacob commented softly. He wanted to touch them but decided it best to wait and see how things go before making such a bold move.

"Why, thank you, Jake. They better be nice... I spent enough money on these puppies," Brenda said while she tossed her bra onto the pile of clothes on the exam table.

"You mean they're fake?" Jacob asked in surprise.

Brenda replied, "I had them enhanced years ago with the best plastic surgeon in the southeast." She then chuckled and nodded towards Karen and said, "Not all of us were blessed with big naturals like your mom over there." The nearly naked doctor then took hold of Jacob's throbbing erection and whispered to the creature pulsing in her hands, "Now, my new friend... where were we?"

Karen sat quietly as she once again played the part of a captive voyeur. On the one hand, she felt relieved that her younger sister was so accepting of her plight and was more than willing to help Jacob, and along with it, keep their secret. However, as she watched yet another woman giving sensual pleasure to her son, she could not help but once again feel slight pangs of envy.

After a while, the chemicals in Jacob's pre-cum had increased Brenda's arousal to a fever pitch. Her nipples burned, and her thong panties saturated. The horny physician snaked her hand between her shapely legs and ran her fingers over the silky gusset, further torturing her already tingling clit. She now found herself desperate to finish up with Jacob and hurry home and take out her frustrations on her husband.

Pulling her head back, Brenda swallowed then said, slightly out of breath, "Damn, Stud, what's it gonna take to make this thing blow?" She then rubbed the side of her cheek and added with a chuckle, "My jaw is killing me."

Jacob saw an opening and decided to take a chance. He reached down and took Brenda by her hand, and pulled her up from the stool, and said, "I'm sorry, Aunt Brenda... let's try something different."

Like with his mom the other day in the laundry room, Jacob guided his aunt to rest her hands on the exam table. With her mind clouded from the extreme arousal, Brenda gave him no resistance, but asked, "What do you mean different?"

Brenda watched in the mirror on the wall as her nephew took up position behind her, and she spoke with slight panic, "Jake... what are you doing?"

Jacob placed his hands onto Brenda's fleshy hips and said, "Aunt Brenda... I'm gonna need you to lower yourself a little more." He then tapped the inside of her foot with his.

Karen instantly realized where this was heading. The memory of the laundry room incident caused her vagina to spasm involuntarily. She wondered if she should intervene, but for some reason, the concerned mother couldn't bring herself to speak up, so instead, she kept quiet and stayed seated.

Brenda knew she should put a stop to this and quick, but her mind and body did not want to cooperate. Giving her nephew a blowjob in order to help extract a semen sample was one thing; however, full-blown sexual intercourse was a whole different level.

Against her better judgment, Brenda stepped out her heels and widened her stance as Jacob instructed. Then, as if on autopilot, she bent over and lowered her naked torso down onto the exam table. The cool vinyl cushioning gave soothing relief to her sensitive burning nipples.

The confused wife battled with internal conflict. Her aroused body wanted nothing more than to experience Jacob's freak of nature. Her well-lubricated vagina awaited to be stuffed like never before. Yet, the sight of her wedding rings brought back the memory from five years ago. She couldn't allow herself to cheat on her husband a second time... but even worse than that... with her own nephew... could she?

Jacob took hold of Brenda's thong just where it disappeared into the deep cleft between the flawless globes of her beautiful backside. He then lifted it and pulled it to the side, out of the way.

At that moment, Karen noticed Brenda's vagina was totally bald, just like Melissa's. In her mind, she asked herself, "What is it with women and shaving their pubes?" She couldn't help but be intrigued by the sight of her sister's glistening clamshell.

In a final desperate act of keeping her fidelity intact, Brenda said softly, "Jake, Honey... I don't think I can do this... I shouldn't cheat... on your uncle."

As Jacob slid the head of his enormous dick along his aunt's sopping wet gash, he replied, "It's not cheating, Aunt Brenda... remember... you're just being a good doctor and helping your patient."

The feel of Jacob's gigantic cock sliding between Brenda's pussy lips felt so good she had to fight the urge to push her hips back against it. Looking into the mirror, the frantic wife locked eyes with her sister in search of help and blurted out, "Karen... I'm not sure I should do this again!"

Looking back at Brenda's reflection, Karen could read the mixed signals in her sister's pleading eyes. There were emotions of confusion, anticipation, and fear, but primarily lust and desire. So instead of coming to her rescue, Karen tried to ease her guilt and said softly, "Don't worry, Brenda... Mark will never find out."

At that moment, Brenda's eyes went wide with shock. "Ahhhhh!!" she gasped as the head of Jacob's cock penetrated her tight opening. As more and more of her nephew's thick phallus slowly burrowed its way deeper into her wet pussy she began to chant in quick succession, "Oh my God! Oh my God! Oh my God!"

Brenda contemplated telling Jacob to stop. However, in an attempt to ease some of the intense pressure, she reached across and grabbed the far end of the exam table. This position caused her torso to lay flat against the vinyl cushion and allowed her to raise her butt higher and give Jacob a better entry angle.

Unlike her older, more conservative, and straight-laced sister, Brenda dated a lot of different guys in high school and college. She even ended up having sex with quite a few of them. However, no one in her past, including her loving husband, had anything in size remotely close to preparing her for the onslaught her nephew was about to bring.

Jacob knew best to go extremely slow, with his gained experience, especially it being his first time fucking his Aunt Brenda. He wanted to do all he could to make it as pleasurable for her as possible because he hoped it would not be the last time.

After feeding her clutching vagina the first couple of inches, Jacob slowly pulled back to where just the head was inside. He would then slowly push forward until Brenda's hungry pussy swallowed another inch or two. The patient teenager would repeat this move over and over until his crotch finally came to rest against his aunt's soft and curvy upturned ass.

While Jacob paused to give Brenda's body time to adjust to his incredible size, he commented, "Wow, Aunt Brenda... I'm all the way inside you... it feels awesome!"

Taking the opportunity, Brenda raised her head up off the examination table. Her only reply was constant moaning and gentle gyrations of her hips. She had never felt so full and could actually feel Jacob's monster cock pulsing deep inside her body. It gave her a weird sense of pride to know she was able to take his entire length.

As Brenda's pussy adjusted to her nephew's incredible girth, the agonizing pressure began mixing with feelings of intense pleasure. She still fought with herself over the guilt of having sex outside her marriage again; but, she remembered what Jacob said earlier and tried to use that as justification. This would not be cheating... this was only to help her nephew... her patient.

With her mind a bit more at ease, Brenda pushed back and ground her hips into Jacob's crotch. She moaned from the delicious sensations that continued to build deep inside her cunt. Looking back over her shoulder, the committed physician said to her patient in a heavy whisper, "Okay, Jake... let's get that sample, but whatever you do... go slow."

Jacob nodded as he dug his fingers into Brenda's fleshy hips and pulled his cock almost out of her sopping wet pussy. He then sank all the way back in with one powerful stroke causing him to moan and his aunt to cry out from the overwhelming, painful pleasure, "Oh my God!!" The teenager then began a slow and steady rhythm of full in and out strokes setting Brenda on a path towards orgasm.

From the chair in the corner, Karen watched the incestuous coupling like a captive audience of one. In an ordinary world, she would be furious and horrified to see such wickedness. After all, this was her teenage son and her married sister committing this salacious immorality. However, she once again reminded herself that until they find a cure for Jacob, their world would no longer be ordinary.

Karen continued to witness the wildly sinful act... the constant groans and moans of her son and sister made her think of two rutting animals in the wild. However, the ordinarily demure housewife found herself somewhat envious of the improper pornographic scene taking place before her.

The jealous mother mindlessly squeezed her thighs together, trying to extinguish the severe tingling in her clit; however, her efforts seemed to have a reverse effect of fanning the flames of her desire and only heightening her frustration. Tonight, her husband Robert would be in for a surprise as his horny wife was going to put him to work.

"Ugh! Ughhh!! Ugghhhh!!" Brenda's grunts grew more intense as Jacob continued to thrust away at her saturated pussy. Her nephew's fleshy spear violently pierced into new areas of her body and ignited nerve endings that, until now, lay dormant.

The new titillating sensations quickly spread throughout Brenda's curvy body, causing her to tense up as the first wave quickly approached. She called out, "Ohhh!! It's cominnnngggg!! Yessss!! It... It's... COOOMIIINNNNNG!!" Arching her back, the beautiful married physician loudly announced the arrival of her powerful climax. "OHHHHH!! YEEESSSSSSS!!"

Jacob continued to piston in and out of Brenda's well-lubricated tunnel as her body spasmed from the overwhelming ecstasy. The teenager once again felt a sense of pride, knowing he was able to bring another gorgeous married woman to climax on the end of his incredible manhood. He then paused for a few seconds as a litany of satisfied moans came from his aunt while she slowly recovered.

Wanting to bring Brenda off one more time before his own completion, Jacob began sliding his cock in and out of his aunt's delightful pussy once again. This time, however, he quickly built up speed and attacked her with more urgency.

"Holy... SHIIIIITTTTTT!!" Brenda cried out. She had barely recovered from the first wave, and now her nephew, not wasting any time, was pounding into her like there was no tomorrow.

Brenda could already feel the early warning signs of the impending second wave. Reaching across the examination table, she grabbed hold of the far end of the vinyl cushion, turning her knuckles white as she held on for dear life.

A continuous stream of "Ohhh... yes! Ohhh... yes!" escaped Brenda's mouth as Jacob's thrusting appendage primed her pump. The tantalizing pressure continued to build deep in her core, and it became evident her next climax would be nothing short of epic.

The lovely physician still battled with a sense of guilt and reluctance. However, the sensations lighting up Brenda's nervous system were unlike anything she had ever felt, and her walls of defense were beginning to crumble. As Jacob continued his relentless attack, the reluctant wife saw no other viable option except... total surrender.

Rising from the cushion, Brenda waved a white flag to her nephew, "Go Jake! Ughhh!! Faster! Ughhh!! Harrdderrrrr!!" The teenager obliged by increasing his tempo and ferociously slamming into her round womanly backside. Each collision of flesh on flesh sent ripples coursing throughout the flawless globes of the cheating wife's big, juicy ass. A lewd 'slap slap slap' sound reverberated throughout the small room.

The extra stimulation caused Brenda to cry out, "Ohhh, Yesss!! Yesss Jake!! Ohhh, Yessss!!" She could feel the second wave hovering just above her, waiting to crash down at any second. Raising her head up, she locked eyes with Jacob's reflection in the mirror. "Do it, Stud!! Fuck Me!! Fuck your Aunt Brenda!! Make me cuuuummmm!!" At that moment, the incredible wave crashed, and Brenda drowned in a sea of ecstasy. "OHHHH YESSSS!! OH MY FUCKING GOD!! YEEESSSSS!!"

Karen should have been appalled by the filthy language that spewed from her sister's mouth. But, she was so aroused from the immoral and vulgar scene that she mindlessly began pinching her hardened nipple through her cotton dress.

That, along with squeezing her thighs together, set off Karen's own mini-orgasm. Embarrassingly, she bit her bottom lip, hoping neither of them heard her shameful moans.

While Brenda continued to ride out the last waves of her glorious orgasm, Jacob cried out to her, "Aunt Brenda... I'm almost there... I can't hold it!!"

Until now, Karen had not even noticed that Jacob was not using a condom. Jumping up from the chair, Karen rushed over and pulled Jacob by his shoulder, "Don't finish inside her, Jake!" She then held out the glass beaker and added, " You need to use this!"

Surprisingly, Brenda turned around just in time to take the beaker in one hand and Jacob's throbbing cock in the other. She then aimed her nephew's dick at the open container and vigorously stroked his shaft. "Okay, Jake... just let it out."

In just a few seconds, Jacob howled as torrential amounts of semen shot out of his cock. The first ribbon splashed out of the jar and onto Brenda's neck and chest, causing her to shriek, "Oh my God!!" She continued to jack off her nephew and commented in shock, "It's just... so much!"

Finally, the flow ebbed, and Brenda was able to collect more than enough for the sample. After setting the beaker down, the gorgeous doctor watched as her nephew's semen streamed down across her boobs and stomach. The naked doctor ran a manicured finger through her impressive cleavage, scooped up some of the creamy liquid, and then popped it in her mouth.

Catching his breath, Jacob apologized, "Sorry, Aunt Brenda... like I said... it makes a mess."

After sucking her digit clean, Brenda giggled then said, "That's okay, Stud. But you best be careful with that thing, or you're gonna end up drowning some poor girl."

A while later, after cleaning up and getting dressed, Brenda tightened the seals on the sample jars. She then said, "Okay... I'll send the samples off tomorrow, and we should have the results back in a week or two." Looking at Karen, she continued, "Want me to call you when I hear something?"

Karen nodded and said, "Yes, please."

After Jacob finished tying his shoes, he stepped up to Brenda and asked, "Aunt Brenda? Would you happen to have anything to drink around here? I'm dying of thirst."

"Of course," Brenda replied with a smile. She pointed to her left and said, "Just go down the hall, to your left, and you'll see the staff break room. In there, you'll find a refrigerator filled with all sorts of drinks and snacks... go help yourself."

Jacob returned her smile and replied, "Cool, thanks!"

"Buuuuut," Brenda said while holding up her index finger. "Before you go, you have to pay your doctor's bill."

Jacob gave his aunt a confused look.

Tapping her cheek with her finger, Brenda said, "My fee... you gotta plant one right here."

Jacob smiled and kissed his aunt's cheek. He then said, "Thanks for everything, Aunt Brenda."

Brenda replied, "You're welcome, Stud. But remember..." She then held Jacob by his shoulders, "What happened here today... must stay here... understand??"

Scrunching his brow, Jacob jerked her chain, "I'm not sure I know what you mean." He then shrugged his shoulders and added, "Nothing happened here today that I'm aware of."

Ruffling his hair, Brenda chuckled, "Okay, smarty-pants."

After Jacob left the room, Brenda sat down in the chair previously occupied by Karen. As she slipped her heels back onto her feet, she asked matter of factly, "Sis... are you on birth control?"
