Kelly had slept for a while but once the sunlight broke into her room and hit her face she stirred. She sat up and stretched. She had felt like she had gotten a good nights sleep.

Getting dressed she grabbed the towels from yesterday, including the one she used to clean her and her brother off from their time "playing" in her room. She put the laundry on and then started making herself breakfast.

Again all normal, or so it seemed. Their parents had already left for the day donor was only the two of them.

 

[shizzz]

Sam had woken up early that morning and gone through the notes he had made last night. However there are several times were he couldn't help himself he stop started flipping through the pictures he had taken yesterday on his camera phone. He sifted through them feeling is conquer Steffi recall the events of yesterday the way his sister had made him feel.

It wasn't very long before he found himself laying back in his bed and masturbating to the pictures on his phone after all she was gorgeous

Soon after he picked two pictures one picture of her when she was in the shower display her beautiful body the other was one of the pictures he took afterwards when where she was bent over the sink leaning against the cabinet her ass pull to the side and her pretty pink pussy plain to see


you could hear movement is he himself got dressed or distant typical sound of somebody messing around in the kitchen and he went downstairs to the kitchen. Had the two pictures ready on his phone in order to address any sort of accusations his sister my throat with him however she didn't seem bothered by it at all

" morning sis are we doing no run this morning I thought you were still running every morning ?" He asked her

 

[Cherrybomb400]

"Gonna take it easy today." She explained as she dug into her cereal. "Don't want a repeat of yesterday." Meaning when she passed out. "Just going to work on stretches and then maybe go to The gym to practice."

Kelly finished up her cereal and then took her bowl to the sink and started cleaning it. She had already put on her yoga pants and a tight top to get ready for her stretches. The pants, much like the ones she wore yesterday, hugged her ass and there was a seam that ran down the middle. It almost looked like the fabric was just painted on! It was also obviously that she was once again not wearing panties. She just didn't like how it felt to workout or stretch when she wore them so when she knew she would work out or train she just didn't put on a pair.

"So what about you?" She turned to him and leaned back on the counter. "Trying to save it take over the world with Science today?"

 

[shizzz]

"Just working on my concoctions"
He said with a smile. His eyes sliding over the tank top she wore. The neckline was very very revealing. He wondered if it could actually hold her chest back under the right stretch

"Yeah. I umm actually made a little hydrating concoction. It's kinda like diet Gatorade on steroids if you want to tryout" he told her.

He himself was wearing a pair of gym shorts and a t short. His work in the lab had been intense, and he had spilled some. The clothes he had just tossed on to appear casual. He was aching to test this mix on her.

"I got a glass
Over here" he said dashing to fetch it and return. He had played to his best bet and hopes the mix was close to yesterday and he had some idea on how to check, without pushing to far. He was kinda curious about her memory of yesterday.

"Dos you sleep well?" He asked with a smile as he offered the drink to her. "I had the craziest dreams"
He said as his eyes dipped to her tight top again

 

[Cherrybomb400]

"Sure," she wouldn't pass at the chance of trying a new sports drink. She watched as he poured it and then took the glass. She sipped it and couldn't help but to show how tart she thought it tasted. Hopefully it worked better than how it tasted.

"Crazy dream?" She asked. She tried to recall any dreams she might have had last night. "I don't remember anything past closing my eyes as soon as my head hit the pillow." She took another sip of the drink. Honestly she didn't like it but she wanted to... She wanted to... What did she want to do?

"This tastes like shit." She said flatly as her body language changed. Her hand rested on her hip and her eyes narrowed. She turned back towards the sink and dumped the rest of the drink down the drain.

"If you're going to give me something to sample at least make sure it tastes better than garbage water." It seemed like this attitude was coming out of nowhere. Her blood was getting hotter and hotter and the target of her anger was directed right to her brother.

 

[shizzz]

He half chuckled at her comment. At first anyway. Then she tossed it! That was not in his plans at all!!

"Whao. I worked hard on that. You have no idea what it takes to make these drinks!" He told her as he half reached out to the sink, but it was too late

"Ugh. Seriously sis. Next time taste it, tell me it sux and give me a chance to fix it" he soda as he ran his big hands through his wavy blond hair, exhaling in a long blast, thinking just how much was wasted here. Well at least he had the pictures, he thought to himself with a half smile as his eyes came to rest on his sisters

 

[Cherrybomb400]

"There was no fixing that shit!" She snapped at him. She really had no reason to be angry with him, it was the concoction he made that was working its effects on her. Kelly couldn't give two fucks about anything.

She pulled her long blond hair up into a messy bun. "I don't have time for your stupid experimental drinks. God, the whole fucking world doesn't revolve around you!" Which was ironic since yesterday she was pretty much at his beckoning call.

She stormed out of the kitchen and started to get ready to head out the door.

 

[shizzz]

He stood there shocked. She had stormed out. A minute ago she was gonna be stretching and now, now where was she going!


He would be responsible for whatever she did. He had to get to, she wasn't safe to be off running about.

He chased after her as she headed to the front of the house

"Hold up sis" he said as he grabbed her arm, and stopping her from getting to the door

"We made a deal about my health drinks a long time ago. So don't give me the blame on that" he said, tugging her back, and twisting so that he switched spots with her. Now he was closer to the door.

"Why don't you just cool off here. Can't have you running off all pissed. It's no way to leave the house. Let me make it up to you, and make you another drink. More tasty?"

 

[Cherrybomb400]

"More tasty? How do I know your not just gonna slip me something funny?" She raised an eyebrow to him. If she had been in her right mind she wouldn't think he would ever do such a thing.

She rolled her eyes and shook her head. "Whatever, go ahead and try." She crossed her arms. She was annoyed that he stopped her from leaving. The more she thought about it the more angry she was getting. Just because he was her old brother he thought he could order her around and do whatever he wanted with her.

She wasn't a Guinea pig!... Ok maybe she agreed to it but that doesn't mean he could just force her to stick around. There was something in the drink that was forcing her to comply. He did tell her to let him make her another drink and so she couldn't refuse it, no matter how hostile she was acting.

 

[shizzz]

" great. Just sit down in the kitchen. I'll be right there" he told her as he hurried off to the basement. He quickly mixed another dose of what he made, only making it half as potent this time because he wasn't sure of how much she had drank before tossing it.

Then he grabbed a little crystal
Light single serving packet and used
That

He hustled up the stairs, careful not to spill it. Then he found her sitting, just like he said.

He handed her the drink, curious.

"Thanks for doing this though sis" he said with a grin.

"Go ahead and get comfortable. This might take a bit to kick in. You'll have to wait here with me for awhile"

 

[Cherrybomb400]

Kelly rolled her eyes and just chugged the drink down. It did taste better but she just wanted to drink the stupid drink and be done with it. She crossed her arms and waited until he was satisfied.

Annoyed by the inconvenience she tapped her foot. The. She looked through her phone. It was obvious that she was restless. "What exactly is it that we are waiting for? There better not be any strange side effects!"

Kelly was building more and more pent up energy. The only time she was this snappy was during her time of the month. As she looked around she felt the bun on her head feeling looser. It almost felt like it was it had fallen as it was no longer on her head but the bun was hitting the back of her neck.

Her eyes widened as for a moment she thought her hair fell out. Her hands reached up and touched her hair... No bald spots. She gave a tug for good measure. The bun was now down to her mid back. She realized that her hair wasn't falling out, it was growing rapidly.

"Sam!!! What the fuck is this?!" She yelled pointing to her hair. Then something else occurred to her. She checked her legs... Just as she suspected, her legs that she shaved yesterday were now hairy.... Which meant.

"God damnit! Now I have to take another shower!" She growled. "How long am I going to be fucking Rapunzel?"

 

[shizzz]

Shit, he cursed inwardly. He had no idea howntat could happen

On the other side, had he cited baldness

"You look great with long hair sis. In sure this little burst will be short" he knew the body couldn't keep that level of growth up for long. He quickly followed her up to the jack and Jill bathroom they shared.

"Quick take off your clothes" he tells her as he get the shower going. He grabs a pair of electric clippers, a mans beard shaver. He though it might help as he turned back to her.

 

[Cherrybomb400]

Kelly grumbled behind him and followed him up the stairs. Kelly was so annoyed, of course she looked good with long hair, it was already long! By the time they got up to the bathroom. The bun was down to her butt but it seemed like it finally stopped growing.

"Fine," she grumbled and started pulling off her top and then her pants. This was turning into a reoccurring theme with them. Kelly undid the bun and found that her hair was so long that it was almost touching the floor. She looked at herself on the mirror. Her hair was so long that she looked like the lady Godiva! When she saw the clippers in his hand she scowled.

"You are not shaving my head," she didn't even think that he would be shaving elsewhere.

 

[shizzz]

"It's not for your head" he told her as he nodded at her body. While the growth was definitely localized to her head. The rest of her body appeared as though it needed a trim. Maybe missing a couple of weeks at most. He had no idea how often girls shaved.

In the other hand, her long hair looked amazing.

It fell over her shoulders , coyly covering her full pert figure, like one of those classic painting.

"I just figured this might make it easier. Then you can shave however. I just was not expecting this growth. So I want to stick around in case there are any other side effects. Either way. This recipe is a no " he said with a smile as he handed her the electric shaver. His eyes driving over her chest, watching the hair part over one full breast, her nipple becoming visible only barely.

 

[Cherrybomb400]

She took the electric razor. The chemicals in the drugs started to subside as her face softened. She looked at the tool, it was clear that she was nervous about using it. "I... I want you to do it." She blushed as she handed the razor back to him. "Never used an electric razor before."

It seemed that this batch had short effects at least shortly after her hair stopped growing. She moved closer to him and started to unbutton his pants and pull them down. "It'll be easier if you're in the shower with me." She continued to pull off his clothes until he was just as naked as she was.

 

[shizzz]

He smiled when she handed him the razor. He was getting ready to agree, but then her hands slid to his shorts, and she began to undo his shorts. The casual nature was extremely erotic to him, that coupled with how little sexual experience he had. His cock began to stiff instantly.

Before he could say nothing to stop her though, his shorts and boxers fell to the floor. His cock was not stiff and obviously erect, but it hung thick and swollen between his legs as his sister casually stood back up.

"Ok. I guess I'll help you. I don't know what we will do about that hair. You should put it back up in a bun or whatever before you get all wet" he told her, hoping his business like approach would distract him from his hot naked sister. Of course if her hair was up, well then her body wouldn't be hidden.

He tugged his own shirt off. And waited to see if his sister would listen. Was it working? Was she complying? She had seemed to have no qualms panting him, maybe this was different. Not like yesterday, but equally enjoyable

 

[Cherrybomb400]

Kelly ended up braiding her long hair before twisting it around and it was like a crown on braids on her head. She pinned it in place before climbing into the shower. She grabbed the shaving cream and started lathering her legs. Finding a comfortable place for her to stand and allow her brother to shave her legs with the electric razor.

Kelly was surprised by how it felt and it seemed like the shave was pretty close. Maybe she should get her own electric razor. It seemed to go faster too. It also felt really nice having someone else her legs, like she was being pampered. After he finished she rinsed her legs and started to feel how smooth they were. They felt really good.

"Feel!" She grabbed his hand lead it to her leg which she had raised so he would feel how smooth her calf leg is. Kelly also liked how it felt to have her freshly shaved legs touched.

There was only one place left to shave. She got the shaving cream and rubbed it over the hair on her mound and between her legs. After she finished applying she just stood there and waited for him to start shaving once again.

 

[shizzz]

The shaving was a little weird, but as she shifted and turned, lifted one leg then the other, he found it very erotic. His hands were sliding over her thighs, bracing on her hips. All the while her hair was piled up on her head and her full round breasts glistened with water, shimmered as littl rivulets courses over her curves.

More than once he had held her plump little ass in her hand. The entries chore had gotten him harder than a rock as he ogled his sister, feeling her ass and thighs every which way, all the whole openly gazing at her pert swollen breasts.

She stopped him when he was done, her hands sliding over the freshly shaved skin of her legs. Then with out a word, she sat him back, lifted a leg and handed him the shaver.

Her pussy was inches from his face. He wondered what it would taste like, how it would feel. He reached up with the razor and began to work on her pubic hair, slowly cutting it back to reveal the swollen mound of her hidden clit. He leaned closer as the trimming becam more treacherous, a hand slipping up to support her lifted thigh. His thumb slipping over her pussy lip as he did

That touch alone drove his heart to hammering.

He had finished and he had to know. Was she under any sort of effect from the drink. He smiled at the thought a she stood up, his stiff cock brushing her thigh, the meat rigid and hungry

He handed her the shaver

"Your turn. You shave me"

 

[Cherrybomb400]

Kelly took the razor. She was surprised when he told her to shave him. She doubted that he meant his legs. He didn't have any scruff on his face, none that she could see. She knew some guys shaved down there, and it was the only other logical place.

Kelly knelt down and then slathered the shave cream over his pubes. She was nervous about shaving someone else and using something like the electric clipper. She didn't pay any mind to his erect cock, it wasn't the first time she had seen it. She was very careful when she started shaving his package. In order to get all of the hair she needed to touch him intimately like he did with her. She had enjoyed feeling him touch her there and wondered if he was enjoying the same touch she was giving him.

Once she finished she inspected to make sure she hadn't missed any hairs. Her hand lightly brushed over his shaft and then around his balls. She was pretty impressed with herself, she didn't miss anything and managed not to nick her brother.

 

[shizzz]

His body aches and trembles. He had not thought through what he was asking, but as she finished he couldn't help but think that it made his cock look even bigger.

His beautiful sister belt before him, her hand gently slipping over his throbbing member as she rinsed his cock clean.

Then it hit him. She had done what he told her to do

A simple command, then he looked down at her

"Tell me, do you like my cock?" He asked, and before she could answer.

"Let me feel these again" he said a Shia hands landed on her breasts. He was taking a big risk, not positive of he was right, but it made sense. He just had to tell her to do it.

His hands closed on her hefty chest, and he squeezed gently, he was half stopped over her, his cock even closer to her face

"Tell me. Do you like sucking dick"

 

[Cherrybomb400]

"Yes-ahhh!" She let out a surprised cry when her brother grasped and lifted up her breasts. Her mouth dropped open as she looked up at him. His cock was so close to her mouth, that's when he asked her if she liked sucking dick.

She blushed a little as she thought about it. Kelly had only done it twice but both times she found that she enjoyed it when the guy would groan in pleasure from her mouth sucking and teasing them.

"Yes," she blushed as she spoke softly, her words almost getting lost in the sound of the shower head raining down water on them. As she breathed her breath was gently hitting his meat. If she wanted to, all she had to do was stick her tongue out and give it a good lick... in fact, as soon as the thought crossed her mind, that is exactly what she did.

Her tongue gave his head long licks, feeling the flesh slide over her taste buds before her would swirl her tongue around the head. The fact that this was her brother's cock didn't bother her in the slightest. The more she licked, the more turned on she because. It was so thick, would it fit in her mouth?

 

[shizzz]

He smiled as she admitted to liking his cock. That made him feel much more appreciated. He let go of her hefty breast as she eyes his meat, then she answered his second question. Before he knew what was going on, her lite tongue was gliding over his long thick pole. His body quivered as he felt the liquid heat pouring off her tongue practically burning his cock. It looked so big when it was so close to her face

And she liked sucking dick, that made him smile even more.

"Tell me. Would you like to suck my dick" he wondered with a grin as he lowered his hand to the base of his shaft, moving his member to tease her tongue and lips as she coyly teased him.

"Tell me all the things you want to do with my cock" he said in avoids that was growing thick with lust, and power.

 

[Cherrybomb400]

"Yes," she answered between licking his cock. Oh god, she didn't know why but she felt her body getting hotter the more she tasted his meat. He asked her if she wanted to suck his dick and she responded with a desperate sounding "yes". She wrapped her lips around the tip and started sucking. She moaned on his member as her head bobbed up and down.

Then he asked her all the things she wanted to do with his cock. She kept her lips wrapped around him as she started to bob her head with more force and sucking more of him down. She pulled back until her mouth released his dick.

"I was to suck on it until you cum and shoot it down my throat and in my mouth," she sucked on the tip briefly, "I want to touch it and stroke it whenever I want it," she started imagining all this as she spoke, her tongue teasingly licking him. "I want... I want to fuck your cock." She blushed but she didn't stop, "it's so big. I want to feel it inside me."

 

[shizzz]

His body was on fire, his gorgeous sister telling him all the things he's dreamed of

She was hungry for his cock

Her lips. Wrapped over his throbbing member and she begin to slide his meat into her mouth

"Oh shit"

It felt sooooo much better than he had ever imagined!!!

Then she paused letting his cock slip free to answer his questions. She wanted it all!!

"You can have it whenever you want it. Wherever you want it" he said as he worked more and more into her bobbing mouth.

He lenses back letting his hands slip to her head and he began to pull her done more

"Take it all in. Intense you to take all 10 inches into your throat "

 

[Cherrybomb400]

She moaned as her brother pushed her head further down on his cock. She continued to make lewd grunting sounds as her pushed her head back and forth with the help of his hand. When he told her she could have his cock anyway she wanted she sucked more passionately. He pushed her head a bit more and her chin was now hitting against his balls.

Kelly wanted to make her brother cum. She needed to drink his warm seed and she wasn't going to remove her mouth until she had every drop. She loved her big brother and she loved his huge cock and she needed to tend to it whenever he needed. She was a good little sister after all.
