Chapter #4Jenny, Her Brother's Cock: Part One by: M.M.69   As you sat there, ogling your gigantic perky tits, your door opened to reveal your sister Jenny.
You froze out of habit, but she didn't appear bothered by the sight of your exposed breasts in the slightest.
"Hey bro," she said casually. "Mom said you got a package?"
She stepped into your room and stood at the foot of your bed, curiously.
"Uh, yeah," you replied. "I just ordered a... um... new case for my phone."
Jenny looked a little disappointed. "Oh, okay."
She began to turn to leave, but suddenly you thought of using the remote on her.
"Wait!" you almost shouted. You were almost too excited to test it out on her.
Jenny sighed and placed a hand on her hip. "What?"
"I was wanting to ask you something."
You selected her with the remote. Her info appeared on the little screen, and you began frantically scrolling through settings and options while simultaneously racking your brain for ideas.
"What is it?" your sister asked again, now with a tinge of impatience.
Finally you found what you were looking for, selected it and clicked the 'Enter' button.
ZAP!
Immediately, your sister's already impressive rack began to stretch her sports bra forward as they grew. You heard the semi-elastic fabric creak and groan as it protested the expansion of its enclosed mammaries.
However, as Jenny's tits grew, their appearance also changed. The skin was darkening, and becoming textured... almost wrinkly. Her cleavage was disappearing by the second as the skin of her boobs began to merge together.
After a few more seconds, and her tits were now very wrinkly, and colored a dark grayish tan that contrasted with her otherwise smooth pale skin.
The growth of her bosom settled once each "boob" was the size of a watermelon. Her sports bra looked as though it was about to snap.
As a final touch, dark scraggly hairs sprouted all over her chest, until the entire region was a sweaty forest of pubes.
It was done. Your sister's boobs were now a giant set of hairy testicles.
She was still looking at you expectantly, completely unaware of the horrific alteration of her body.
"Ummm," you began awkwardly, unable to pull your eyes away from her dark hairy "cleavage". Veins webbed throughout the almost translucent skin of her enormous sack, and her gigantic nads audibly gurgled and sloshed as they produced probably gallons of hot semen. "You take care of yourself, right Jen?"
Jenny scoffed and rolled her eyes. "What kind of question is that? Of course I do, dork. I go to the gym every day!"
"Well I was just wondering... You take such good care of yourself, but why don't you shave your balls?"
"My balls?" she queried, raising an confused eyebrow. For a moment you thought she might see what happened to her tits and freak out, but instead when she looked down at her "rack" she merely smirked and raised a hand to caress the top of her chesticles, running it through the dense pubes in the process. "I mean, I've thought about it. But I kinda like the au naturale look, you know? Besides, Brandon likes them hairy as well."
You almost laughed. It was comical to think of her boyfriend Brandon, a veritable dude-bro who's about a straight as they come, to be attracted to your sister's monstrously giant and hairy chest-balls. But it was good to know that the remote really does adjust reality to fit whatever changes you make with it.
"Do you ever go freeballing?" you continued. "You know, let em swing?"
"Uh, DUH, where have you been?" she chuckled. "I only wear a bra like this when I'm going jogging or something. You know that. Although, come to think of it, I don't know why I put on such a tight bra today. My boys feel like they're suffocating!"
With that, Jenny gripped the bottom of her desperate sports bra and pulled it upward. Her balls went with it, allowing you to see their smoother and less hairy underside, as well as the seam where they connected to her chest.
A short struggle later, Jenny managed to free the bra from her enormous testicles, which promptly flopped back down onto her torso with immense weight.
"Ahhhhhhhhh," Jenny sighed with great relief. "That's so much better." She dropped her sports bra to the floor and set about massaging her balls with her hands, smiling down at them as they shifted and rolled around.
Just as you suspected, there were no nipples to be found. These were 100% genuine human male testicles hanging from her chest. They smelled as well; a strong musky sweaty masculine smell that almost burned in your nose.
Seeing your sister playing with her chesticles inspired you to add another change into the mix. You aimed the remote at her again.
ZAP!
"Ughhhh," Jenny moaned. "All this massaging my balls is making me hard."
You quickly saw exactly what she meant.
Her neck was gradually extending. The veins on it were visibly swelling with blood. Her neck broadened and slowly took on a more tubular shape.
1 foot long... 2 feet long... 3 feet long.
You stared in wonder as your sister's head traveled further and further toward the ceiling. She was always statuesque in height -- over 6 ft -- but now she dwarfed you.
You could hear her cockneck creaking and straining as it continued to expand, and her balls were gargling even louder than before, being encouraged to produce even more cum for their cock.
"Ohhhhh goddddd," your sister moaned again, her head now 4 feet from her shoulders. "I'm almost at full mast." She removed a hand from her balls and glided it up the side of her thick heavy shaft. Her neck throbbed in response to the touch, causing her head to wobble around at the top.
Just as she said, it was only another inch or two before the expansion ceased. Your sister's neck was at a complete erection. She sputtered as a flow of pre gushed from her mouth and down her chin.
"I-I should probably g-go and... nnggg! deal with this in my r-room," Jenny stammered, face clearly flustered. Her thoughts were swimming with lewd images: her boyfriends ass... her mother's spectacular tits. "U-unless you're fine with me shooting ropes all over your room."
You grinned up at her. "I don't mind at all, Jen. You can jerk off all day in here, if you want."
Your sister looked relieved. She really didn't want to travel all the way to her room, especially with how low the doorways are!
You admired your sister's new look, of course, but you felt you could take it just... another step forward.
Zap!
At the top of Jenny's 4 ft long neck-shaft, skin began bunching up just under her head. The skin darkened and folded on itself, becoming a thick ring of foreskin.
Once it was formed, you watched as the foreskin slowly began to slide up Jenny's head. The folds flattened out as the invading flap of skin swallowed your sister's jaw, then her mouth, her nose, her ears, her rolled-back eyes. The last to be enveloped in foreskin was your sister's platinum blonde hair.
Just as the last bit of her ponytail was slurped inside, the foreskin reached its full extension around its cockhead. It's dark tan skin was now smooth, surrounded by thick bulging veins pulsating with need.
Jenny's hands reached up and explored her cock. They slid around and reached upward, almost as if they were wondering where her head went.
And the answer to that was soon to be revealed, as they gripped her throbbing shaft, and firmly pulled the skin downward.
At the top, Jenny's foreskin noisily rolled back, revealing that your sister's head was... no longer there.
In its place was a regular human cockhead, purple and smooth, even a little shiny as it reflected your ceiling light. A steady flow of pre oozed from the vertical slit at its end.
"Say Jenny, did you do something different with your hair?" you asked sarcastically.
There was no response. Her hands just began pumping at her giant cock. Her melon-sized glans was repeatedly half-swallowed by her thick foreskin as she masturbated.
Made sense. She had no ears or eyes anymore, so how could she respond?
You giddily imagined that her thoughts must not be so different from a cock's at this point. Without any senses other than touch, her thoughts were probably BREED BREED BREED CUM CUM CUM
This was validated by her hands roaming even more ravenously around the bulging expanse of her shaft. She was desperate for release, she couldn't jack herself off fast enough.
With these observations in mind, you were inspired to complete your sister's transformation. Selecting her with the remote, you opened her settings.
About midway down the list, you spotted 'Identity'.
You grinned and opened the menu.
Inside it listed everything there was about who Jenny was as a person.
Daughter
Sister
Girlfriend
Former Track Star
Former Magna Cum Laude Student
et cetera
'Cum' was right, you thought, as you deleted all the info and typed in a replacement:
My Cock and Balls
You clicked 'Save Changes'.
The remote dropped to the floor as you were suddenly overwhelmed with foreign sensations.
"Ouugghhh GOD," you groaned, clutching at your groin. What you felt within was your genitals sucking themselves into your body. In only a moment, they were gone. Pulling your pjs forward, you looked through past your cleavage to see that only a featureless patch of hairy skin remained between your legs. No hole of any kind.
At the same time, your mind was flooded with the pleasure from Jenny's masturbation. Your brain was now wirelessly connected to the giant human cock standing at the foot of your bed. You could feel everything; as real as jerking off your own cock ever felt.
"Fffffffffuck!"
All you could do was lie back on your bed and rest limply while your sister -- well, your cock now -- did its best to pleasure you. You felt its hands sliding around square feet of cockflesh, occasionally reaching a hand down to heft a massive nut and massage it. You could feel heaving quantities of cum swelling within your new balls, as a gallon of pre gushed out your slit.   indicates the next chapter needs to be written. |
