In the small hours of the morning, nothing could be heard in the house. Amber and her sister were sleeping in their own bedrooms, their parents down the hall safely tucked away in theirs. The twins had always been close, a pair of stunning redheads, they looked almost alike aside for the subtle differences that few noticed. A difference in walk, slightly larger breasts, slightly more athletic thighs, their freckles arranged in different patterns. Many times they had fooled strangers by swapping places but that had been a simpler, less frustrating time.

Once puberty hit, the two had taken completely different paths. Whereas her sister had been outgoing and friendlt, Amber had become more reclusive, studious. She'd given up all sports and wouldn't even come down the beach these days, regardless of the weather. She eschewed tight fitting clothes, instead favouring baggy, casual wear that gave her a somewhat tomboyish appearance, a far cry from her sister. When she had moved to her own room, Amber had relaxed a lot more but anyone could tell that it had caused a gulf to open up between her and her sibling.

It should have been quiet except that Amber was not asleep. She found that she was often troubled with recurring dreams, dreams that wound her up and left her feeling stressed and frustrated once she woke. She couldn't remember the last time she'd had a good night sleep without having to 'relieve' herself. As she lay on top of her sheets, warm in her white shorts and tank top, she knew what would help her to drift off again, even if the thoughts were strictly taboo. As she closed her eys again, her hand slipped across her soft bosom and then further, across her belly.

Just a quick one, she told herself, enough to get her back to sleep. In the gloom, she had not noticed that her door was slightly ajar...
 
For the past few days now she had noticed not only her sister was tired in the mornings, but also strange sounds were coming from her room. And despite the fact they had separate rooms for a reason, Emily couldn't help but go and check up on her sister and find out what was going on. Afterall they were sisters and up until recently they were practically inseparable.Emily hadn't really noticed the gap between the two of them, imply thinking Amber had her own ways of dealing with things going on around them. And since their parents had never explained much to her, Emily knew nothing about her sister's condition. Despite that she spent whatever time he could with Amber, but that even proved difficult as he two grew apart bit by bit.

The girl began to wonder why her sister had suddenly chsnged, or at the least grew so distant from her. Amber rarely did anything outside, didn't seem to enjoy dressing like a girl and such, and she couldn't get a direct answer from her.So with the door slightly opened, Emily looked inside, about to speak as she watched her sister lay there on the bed. Her eyes watched in silence however as her eyes followed Amber's hands, watching as she began working her figure. She swallowed a bit, her breathing slow and deep, wondering what her sister was up to.
 
As one hand crept across her chest, caressing the roundness of her full bosom, the other slipped beneath the cotton of her shorts and began to touch her sex. She gasped as her fingertips made contact and she felt her nipples pucker as the pleasure began to flow through her. She wished that something so weird didn't feel so good, that her repulsive changes didn't make her feel so amazing inside but she couldn't help it. As her fingers brushed against her hard nipple, the other hand began to stroke and work on her nether regions, a flush overcoming her freckled face.

Oh how she wished she could tell someone but who would understand? No-one, not even her sister would be able to sympathise, to come close to comprehending what changes puberty had brought to her. First there had been the lump, then a swelling and then a growth that she was terrified of yet reluctant to report to anyone. None of their books or sex-ed classes had prepared her for this. All she could do was hide away, keep it secret. But oh dear gods, how good it felt! As the amazing feelings ran through her, she felt herself swell, a bulge growing underneath her shorts, getting bigger and clear to see even in the pale light. She rubbed her hand over it, her mind lost in thoughts of lust, of forbidden thoughts and the joys of unbridled passion.
 
Still she watched, eyes glued to her sister as she watched the girl fondle herself. Emily felt a strange warmth and tingle between her legs and in the pit of her stomach, gtting aroused a the sight. Aside from them being sisters, what she was watching was more or less like porn, only it was happening right in front of her, and all she could do was watch. Her breathing picked up, hands roaming her own slender figure until she had one hand cupped around her breast and the other dropping into her pants.

Swallowing hard, Emily bit her lip to fend off a soft moan as her fingers dug into her snatch, eyes locked on her sister as the girl played with herself. But when she saw a bulge growing in Amber's pants, Emily's eyes widened a bit, shaking as she stared, unsure what it was. And wih the way Amber squirmed and moaned she could only imagine what it was, her breath heavy, her legs shaky a she stood ther, lust flooding within her, aching to be released.

With a low breath she topped herself, biting her lip hard as she cleaned off her fingers which dripped with her juices."A-Amber?"She called in a breathy tone, waiting for a response before entering.
 
So lost was Amber in her lust, she didn't hear Emily's approach or her whisper. He touching was becoming more urgent, the need to pleasure herself a desperate priority. Her eyes were closed and as one hand groped her breast, the other pushed aside the cotton of her shorts and exposed the bulge that had been growing there.

Exposed to the air, the flesh of her thick, rigid cock sent a shudder of pleasure through her, its bulbous head fully engorged. Rolling her head to one side, Amber did not look at the monstrous organ but gladly wrapped her slender hand around it and began to pump it back and forth. The beast quivered as the jerked it, her breathing going from sighs to increasingly urgent moans. She had to be quick, she needed this so she could sleep even if it meant touching her mutant organ.

She rubbed her cock back and forth, eagerly pursuing her elusive orgasm as she bit her lower lip before sighing, "Oh Emily...!"
 
She could only watch, eyes wide and shaky as Amber pulled aside her shorts and revealed the monster of a cock that plagued her, the beast throbbing as she began stroking it, tending to its lustful needs. Emily took in soft, sharp breaths of air, watching as Amber was oblivious to her whisper, only to call out her name as she pleasured herself which brought a blush to the girl's cheeks. he couldn't believe what she was hearing, and everything began to make sense with how Amber had started distancing herself from Emily.

But another swallow moved down her throat as she slipped inside, taking a breath as she stayed by th door."A-Amber..?"She called out in a breathy, labored tone, her bed pants soaked in her juices, the girl fighting the urge to dive her hand right back at her cunt.
 
This time, Amber did hear and her eyes shot open to see Emily standing, watching her from the doorway. In an instant, she pulled the bedding over her, removing her massive cock from view. She gathered the sheets to her chest as she sat bolt upright, breathing heavily and terrified of what her sister might have seen.

"Ems!" she gasped, her eyes wide. "What's wrong? What is it? Did you have a nightmare?"

Amber tried to sound as natural as possible, scared of what her sister might have seen in the dim light. She didn't see anything, she told herself but she already knew that she was in deep, deep trouble. Strangely though, she did not feel bad about it, instead the buzzing deep in her stomach just grew louder and more intense as her cock twitched beneath the covers.
 
She watched Amber as she quickly hid herself and sat up, Emily slipping into the room, shutting the door behind her. Shaking her head at the question, Emily crawled into the bed, sitting beside her sister. And as much as she should have been freaked out, and disgusted, Emily was far from it. Instead she leaned into her sister and hugged her close.She simply kept silent, hugging Amber close, relaxing where she was. She decided not to push the matter just yet."W-What were you doing..I heard moans...and you calling out my name..."She pointed out, seeming to let Amber know she was around for that much at the least.
 
Amber sat rigid and still as Emily entered her room and climbed into bed with her. It was the closest she had been to her in years and the thought of her sister finding out what she had hidden between her legs terrified her. She clutched the bedclothes as close to her as she could, frightened of her sibling's discovery.

"I was..." stammered Amber, not sure what to say. She knew! She could tell and it freaked her out. "I was just... lonely. I think... I think I had a bad dream.

Emily was next to her, holding her in a way that she hadn't experienced for years. She felt the comfort and pleasure of being touched by her sister but between her legs, her throbbing organ became swollen at the feeling of Emily's touch, moisture bubbling at the crack and seeping into the gathered sheets.
 
Emily listened as Amber explained why she moaned and the like, Emily knowing herself that wasn't true. till she sat there, resting her head on her sister's chest, listening to her heartbeat. She relaxed a bit more now, smiling som as she pushed the covers from Amber's hands."Try again sis.."She whispered, pushing herself closer to the futa.

"I saw what you were doing..."She pointed out, looking up at Amber with a soft, innocent smile.
 
Feeling Emily starting to move the covers, Amber immediately became flustered.

"I... um.. no! I was just... stop it...!" she stammered, pulling as many of the covers back over her as possible. Another time, this would have been funny, the type of high school pranks she'd enjoyed back in the day but not now. She struggled to retrieve the sheets, her cover disappearing rapidly.

"I just... c'mon.. you must get.... frustrated too," she stated, her freckled cheeks already burning with shame. "Stop it... I'm not decent under here...!"
 
She stopped when Amber asked her to, Emily moving her hand away only to pull Amber's to her, letting the covers fall, leaving a tent where her erection met with the covers. She ignored t for now, snuggling into her sister as she sighed."I do..But..I don't tend to it like you did..And yet you also called out my name.."She grumbled. She looked up at her sister and gave her a smile.

She knew Amber would tell her if she was ready, and given how far apart they had gotten, she was eager to find out for herself."Why don't you ever spend time with me anymore Amber? all you do is hide away in here..."
 
Amber's cheeks went scarlet, blushing hard and doing her best to try and conceal herself. She was painfully aware of her rigid cock pushing its way up through the sheets but if she tried to roll over, it would have brought her face to face with her sister and that thought only made her erection painfully more hard.

"I... I was half asleep I think..." she stammered, praying that her dick would go down. "I... I spend time with you all the time... like breakfast and... other times..."

Her voice petered out and she ended up looking sheepish, one hand coiling her radiant auburn hair. She couldn't help it, the proximity of her sister, once such a comfort to her was now erotically stimulating and she hated it. She was painfully aware of how excited her cock was and how close she had been to orgasm when Emily walked in. It wouldn't take much to put her over the edge. Please just go, she thought to herself, willing her sister to leave...
 
She could tell Amber was trying to hide it, refusing to let her see or even know about what she was doing. But she knew and wasn't going to let it go. So with a sigh she kissed her sister's cheek."Not like we used to though..we were always inseperable and always had fun.."She pointed out, resting her hand on Amber's thigh, just inches from the tent of the covers. She watched, waited to see what her sister would do.

When it seemed apparent that Amber wasn't going to say much more about the matter, Emily took in a breath."I-I saw what you were doing sis...such a dirty thing..."She teased. not moving away at all. She herself still wasn't sure about this, but wanted answers, and at the same time couldn't shy away or dny the strange sensations she felt when watching Amber.
 
Amber shifted in the bed, realising that her words were not making her sister go away. She was lying next to her, uncomfortably close and it made her attempts to get rid of her throbbing erection harder. If anything, Emily's proximity was making matters worse. When Emily kissed her she went a shade of red, her many freckles blooming with her embarrassment. Was it bad that she had liked it?

"I know but... things are different now aren't they?" she continued. "We have our own lives and stuff...!"

Amber jumped slightly when Emily put her hand on her thigh. Dammit, why was this making her so hot? Why was her sister's hand being so close to her cock exciting her so much. She gave her a weak smile but then became aware of a cool sensation at the tip of her member. Emily's closeness had caused her to start leaking pre-cum and it was soaking its way through the tent caused by her large prick...
 
Still she listened as Amber continued to pry and try and get her to leave, without being mean and saying just that. But Emily was determined to get her sister to open up, to admit her feelings. She had grown tired of how distant they had come, disliking how she couldn't hang out with her sister all the time because she had other things to do. However she had a good idea now as to why, but had to make sure herself, even if the huge bulge under the covers wasn't enough.

"Or because you think you're so much different than me?"She asked, her eyes looking at the tent, her hand moving over it, pressing down softly. Her cheeks brightened, swallowing hard as she felt it throb, her own body tingling, her eyes forcefully shifting back to Amber.
 
The moment Emily touched Amber's throbbing cock, she sat upright in bed and gasped, lightning bolts of pleasure shooting through her. Although she had fantasized about it often, no-one had ever touched her there and the feeling was orgasmic. She clapped her hands over Emily's not wanting them to ever leave her, her prick quivering to finally feel the caress of another person. The fact that it was her sister just made it even more dangerous, so wrong and yet too amazing to suppress.

"Oh god!" she cried. "Don't touch me there...!" Yet she did not let go as the feelings rippled through her, exciting her in ways she had only dreamed about. She turned to face her sister, trying to read her expression in the dim light. What was she doing? What did she want? Amber didn't care as long as she kept touching her...
 
She smiled a bit more when Amber gasped and quickly sat up, her eyes watching as her hands clutched to her own, keeping them on her cock. Feeling the throbbing and twitching brought a darker blush to her face, wallowing hard at the realization that it was real, her loving sister had a real cock. Emily only giggled when her sister pleaded to her not to touch there, all while her hands firmly kept Emily from moving her hands."Why? you were touching it.."She pointed out, grinding her hand roughly on the covered, engorged cock.
 
Amber struggled to reply, the sensations shooting through her were too powerful, too taboo for her to reconcile. Everything was wrong and yet it felt so good. Why was Emily touching her like this? She felt scared and wanted to run away but at the same time, didn't want it to stop.

"I... I... It's personal... please," she whined, not sure what to say. She recognised her sister's wicked streak, it had got them into all kinds of trouble when they were younger but now she could tell it was leading to a new kind of trouble. "It's... wrong, I'm wrong... I shouldn't have this..."
 
She watched her sister struggle, smiling all the more as her eys watched and her hand pushed down more. She loved getting into trouble with her sister, lways enjoying the time they spent together, regardless of what came of it. And this was no different. She saw her sister having trouble and as many time as she denied her offer for help, she was not going to hear it this time.

"Stop talking like that Amber..Yopu're perfect..and anyone would be happy to have you."Emily assured her with a smile, snaking her hand beneath the covers and pulling them away, tossing them to the floor.
 
Amber tried to remain calm but it was difficult with Emily pressing down on her hard dick. There was no letting go of this now, she knew how persistent her sibling could be when she wanted something. It was annoyingly cute yet she still felt pushed to talk about it. She even blushed slightly when her sister complimented her. For a few seconds there was relief and then suddenly the bedclothes were on the floor, leaving her naked before her.

Amber gasped but it was way too late to cover up her swollen organ. Her pants were pushed down to the tops of her thighs, exposing her throbbing cock. It was large but not preposterous, a thick phallus of pulsing flesh and a smooth, glistening head. The shaft was slick and smooth, slightly broader at its base where it sat just about Amber's pussy. Her sex was almost obscured by a tight pair of balls that sat beneath it. Unable to hide any longer, she lay in bed, not sure what to do or say next.
 
She watched as her sister lay here squirming trying to resist her still. But when the covers hit the floor, she still stared at her sister, not saying nothing for a few moments, wanting to see what Amber would say or do next in response to being exposed. But when nothing came and she simply laid there, letting everything be seen, Emily swallowed a bit, her bare hand no rubbing the thick phallus teasingly."So this is why my sister has been so avoidant and everything..?"She mocked with a playful giggle. But with a breath she leaned down, snuggling with Amber"And I don't suppose It was me..that made this thing so hard and...yummy looking?"
 
"Emily, stop... you don't know what you're saying..." gasped Amber as she felt her sister tug on her rigid member. She squirmed in the bed trying to resist the temptation to leap on top of Emily and drive her cock into her.

Her lust was dangerous, so wrong... How could she possibly tell her sister how much she admired her beautiful body? How often had she stood in the shower and jacked off her mutant cock while thinking about her sibling? She told herself that fantasy was permitted but this was going beyond just idle daydreaming, this was wrong, perverse. So why did she not just stop her sister from playing with her?

"This is... it's wrong... you're my sister...!"
 
Emily listened, shaking her head some as her sister continued to protest, continued to deny how good it felt. She now knew what was going on, why her sister was so avoidant and more, and with such a large phallus between her legs, how could she not talke advantage and d what she wanted.. Bu when She explained how wrong it wa, Emily simply shook her head."I'm just trying to help my sister feel so much better...I'm tired of you avoiding me and not doing the things we used to do...Besides..It isn't wrong if no one else knows....right?"
 
Amber squirmed, her toes curling into the bed as she felt herself become even harder at her sister's touch. Why was she doing this? Every part of her know that what Emily was doing was wrong and yet her body screamed to reach out and embrace he sibling. She looked up at her, the conflict apparent in her eyes.

"No-one... no-one has to know?" she stammered, her fingers slowly grasping her sister's waist. Her darkest fantasies were coming true and it was both terrifying and exciting to witness. "It can be... our secret...!?"
