Flash of Lightning

Hannah was old enough to take care of herself. Even at the age of 18, the calamity of storm sounds seemed to get the best of her. If the low grumbles of something in the distant sky made her heart skip, then the horrible crackle this night made her choke on tears. She tried her best to hold her breath until it all passed, but she found herself up and out of bed quickly making her way to her siblings room.

Too scared to think about getting into something more appropriate. Hannah crept down the hall in the dark empty house in her tank top and panties. Her young mind was still not aware of how she presented her vivacious swelling figure. She grabbed the back waistband as she slowly made her way down the hall. Her big hips squeezing out where they could.

When she could see the dim light from the crack in her brother's door she started feeling safe. Gently opening the door she looked around through the night to see if she could see him. The storm's constant murmur was disturbed by a loud boom. Hannah saw the streets through the window go darker than they ever had been.

She couldn't help but yelp at the ghostly sound of everything purging its last energy into a void of quiet. "Hello, is anyone there?" she could hear her brother's voice. Thank God he was awake. Was he scared too or had she startled him? As always he was more than inviting to comfort her. He invited her to sleep in his bed.

She entered his room shyly. Cautious to not make any disturbing noise. She thanked him as she seated herself on the mattress. Her big butt was cradled deep by the soft cushion. When her cheeks snuggled into the unoccupied fabric she was made aware of how awkward it was that she came in her undies.

It was dark but the windows gave an almost radioactive glow as her eyes adjusted. It seemed to make her yellow satin panties illuminate. There's no way her brother wouldn't know how barely dressed she was. The thunder cracked again though and before she knew it she was under the covers backing into her brother. "Hold me" she was almost in tears.

His arms wrapped around her and he came up close behind her. She felt an instant peace as his hot body pressed up and spooned behind her. As she relaxed into his embrace she was hesitant to completely let go though. She was still bashful about her attire, and the thought of her big butt on him made her feel weird to say the least.

He got there before her though. She froze as his body made contact. In a perverted way the only thing she could think of was how there was only a thin layer of fabric between them. She kind of wiggled her hips in thinking about it. She could leave to put on shorts but that put her in crippling fears way.

So she tried her best to stay perfectly still. It was awkward enough that a nearly grown ass woman was still this afraid of thunder. They were siblings, after all. After about 5 minutes she was able to rest while the chaos swirled outside. She adjusted herself for maximum comfort, but there was something off.

Protected in the embrace of her supposedly sleeping big brother she could feel something protruding below. She was subtle but pushed her big rump back to inspect. Was her brother really asleep?

She had to be sure so she waited a moment and pushed back again. She could feel something firm cradling between her cheeks. Was her rump actually exciting him?! Maybe if she just got to sleep she could never have to think about how weird this was. It got weirder again when she felt him nudge forward subtly.

One thing was when she was scoping out the situation. Him pushing into her was something completely different. Her heart skipped a beat as she felt intruded upon. She would have said something but she was absolutely terrified to even pick her head up. So she just laid there as her brother pressed his hard on gently into her again.

The second time had blood rushing to her head. "This is really weird " she kept thinking as her temperature rose. "I must be such a pervert". Her body was starting to respond. She was hot and she could feel the blood start to percolate in her veins. When he humped on her a third time she found her big luscious booty humped back.

Hannah wasn't just afraid of the storm now. Something else was happening and she couldn't stop her budding body from responding. She anticipated him banging again so she turned her hips up to receive the knock on her love cushion. She was afraid of how enjoyable this inappropriate game was.

From outside the covers you would never know but this play went on for about 10 minutes beneath. Hannah and her brother didn't say a word to acknowledge what was happening and after some time things progressed. Her brother was now pushing up against her hard.

It wasn't forceful but firm enough to be obvious. Hannah had never been touched by the opposite sex let alone her brother. And now he was full mast giving her a major wedgie with his thing. She was getting warm enough to feel herself perspire. If she didn't know any better she'd say she could feel herself getting wet.

She continued to present herself as he rhythmically pushed on to her but now she was pressed with another challenge. She could feel the dampness between her legs cooling as he pulled away. "How embarrassing" she thought in her naivety. "If this goes on I'll soak through" there wasn't a thought about where this was all leading.

The culmination of her anxiety and sexual excitement had her quietly panting. She felt so protected and safe in his bed but should they be doing this? It felt good to give in and let him take control. After all she needed to be subdued by dominant safety.

She felt him shuffle behind her for a moment before she could feel the hotness of something bare against her satin backside. "Of course he would take it there" she thought. "He's already enjoying my ass so much it's only natural that he'd want more" The voice in her head was calm and she even caught herself rationalizing this behavior.

She was dealing with layers of emotion, but she was kind of proud of how cool she was keeping it. She actually thought it was kind of hot. Her own brother couldn't resist her. his skin glided over her fabric. She resumed her own humping again. She bit her lip thinking that maybe she wanted more too.

She breathed heavily in the dark as she let her brother explore her. His hand now on her hip. Hannah was struggling against her desire. She wanted to push the envelope but she couldn't bear the thought of how wrong this was. This was bordering incest.

Her eyes grew wide at what happened next. She could feel it on her bare skin. she covered her mouth to keep herself from breaking their silence as her heart fluttered again. Hannah's growing hips and thighs often had trouble being contained. This time was no different as her panties slid down her plump skin with their movement. She humped back anyway hoping deep down that they would slide down further. They did.

Hannah's eyes rolled back as she could feel his thick cock between her buns. Her pussy was tingling and she knew that all they needed was to touch to release the river accumulating. As she pushed back against his cock she tried to point her hips up. She just wanted to see if it felt as good as this.

He caught on quickly. She almost teared up when she could feel the hot head of his cock finally hit the bottom of her slit. "He must want to touch me there too" she figured as they now shamelessly humped in bed. One hand now reaching behind to grab a thick asscheek to spread herself.

His head was slick with a wetness she could only assume came from her. This felt too good. She had to hold her breath to keep quiet. Although they were now both engaged in obvious activity she couldn't bear the embarrassment of letting her brother hear her moan. It was becoming difficult.

Aside from her careful gasps for air Hannah kept perfectly silent. By now her hips were trembling as the overbearing sensation was starting to take over. Every time her brother withdrew he seemed to motion forward more forcefully through her meaty pussy lips. She didn't know how much longer she could stay quiet while he churned her juices

The pace of things came to a screeching halt when one of the biggest cracks of lightning exploded overhead. Hannah couldn't help but cry out as it completely took her by surprise. It wasn't just the lightning that made her scream though. Her sudden movement took things to a whole other level.

She had no choice but to speak now as they laid there Frozen in place. The head of his apparently thick member wedged into her entrance. "H-hey I um think this has gone f-far enough" she stuttered as she tried to deny how good it felt. "W-we c-can't sh-shouldnt". It was no use though. Her eyes literally crossed as her slippery pussy swallowed the head of a cock for the first time.

"H-hey um wha-what are you d-doing back there?" she asked, although she could figure it out for herself. She waited for a reply but all he asked her was if she was ok. She had to narrow her mind past all the stimulation to really formulate an answer. "I'm f-fine b- but what are y-you doing t-t-to me. D-down there... This is sex isn't it? D-do you really want to do that with me" she almost wasn't ready for the real answer.

Under his comforter she could feel the humidity from their heat and her damp anxious body almost suffocate her. It was difficult to think as she was burdened by her fear of the storm, and the need to be somewhere safe. Now she bore the weight of a third dilemma. The confusing lust for her brother to do more. She finally cleared her throat to speak "should a sister and brother b-be d-d-doing thisss" the head of his cock gently fucking it's way into her entrance.

She could tell he was trying to stay still but it was no use. Gravity and her now wet pussy had them gently coming together. It was only a matter of time she told herself. She held her breath as the brilliance of lightning flashed silently. She braces herself for the inevitable explosion of weather racket. "Oh God please hold me tight!" She yelped.

As she finally released her tensed body she found herself tight in his arms. As he pulled her close to rescue her from the storm her simmering twat returned the favor by inviting every inch of her brother's hard cock. She whaled quietly as she held a handful of bedsheets up against her mouth. "I'm so scared right now". She wasn't just talking about the storm. Their hips now pushing firmly against each other.

She laid there panting like a dog bracing herself as he built up the momentum. He was really fucking her now. She could barely speak anymore as she began to sweat. The blinding pleasure made it easy to accept her fate. "O-ok j-ust this one. P-p-please be careful though" he was now squeezing into depths that had never been touched. The tree branches slapped violently against the window but the only thing she could hear now was the slapping of her own brother drowning his dick in her pussy juice.

body sunk into the mattress as his weight bared down on her. It didn't cross her mind again to question the sin as his dick coaxed her onto her belly. She had finally kicked off her soaked undergarment. In one final declaration of acceptance she parted her legs and rolled her hips up to present herself. "You can keep doing; whatever this. We can k-eep having iincessst s-sex but, please." She pleaded "don't forget to hold me when thunder strikes" she spoke in a trance like song.

Their rhythm slowly synced and Hannah had the hang of things now. Her entire being was being raptured by sin. This in itself seemed to seer though her inexperienced neurons. Then something else started. "S-something feels weird..." She whispered. Her brain now caught in the repetition of his withdrawal and her reception. She focused hard on this strange feeling that was building in her. It felt good.

She tried to dictate to her brother what was happening, but she couldn't explain it. "Something f-feels l-like it's tightening up inside me. I can feel it d-down there too. Like a beating heart." Her brother knew what she was talking about. Before she even mentioned it he could feel the pulses of her overburdened womanhood struggling with stimulation.

The room strobed with the brightness of the storm reminding her of the terrors outside. "Oh it's a big one" she shrieked just as the sensation below her navel became unbearable. "Oh my god it's too much! You have to hold me! You promised!" Hannah was hysterical as he seemed to ignore her pleas to administer the final blows to her virginity. "Please!..."

It was only moments later Hannah figured out his delay. She felt her belly tighten as he caressed her insides and the gentle pulsing of her pussy turned into a violent seizure. He delivered several more blows before leaning over her just in time for the loudest thunder they ever heard. She orgasmed in his arms as the loud noise was replaced by the gentle pitter patter of droplets.

"Wh-what's h-appening" she went limp on the bed. Her brother slowed down but he continued his love on her. "T-thank god it's over" she felt like she had to clarify though. "T-The storm not the s-sex... I don't know what's happening to my body right now but you held up your part. You held me during the height of the storm..." She gathered her strength again to arch pushed her butt up. "I guess t-this was my part" he put her hands on her hips and started again.

Towards the end of the night her brother was on top of her pushing in as far as she could. The only thing she could do was give it to him. She groaned as she began to receive the third orgasm of the night, and for that matter in her life. To her surprise she could feel the warmth of her own fluids running down her ass as she came. The familiar pitter pat of rain was actually her own on the saturated mattress

She was starting to familiarize with the cues of orgasm, and she thought the roller coaster would never end. After what seemed like an eternity of love spasms she could feel him slow down. She could finally catch her breath as his cock traded speed for a deep firm massage.

"You can't give it back now that you took it" She said but, before she could choke out again "P-please be care-ful." her body began to tremble. It's almost like her pussy knew before she did. Again she was immobilized as her own brother grabbed her hips and leaned in as he throbbed inside her.

She felt his thick meat tightly sealing the opening of her pussy. The feeling of his blood pounding against her inner walls. She didn't know where he put it all but she could feel a tidal wave of hot cum as it splashed in pulses at her depth.

They remained silent. As they both came down from their own hurricane of emotions they remained still. For what seemed like a good ten minutes Hannah couldn't bear to move and her brother seemed the same. She stayed tense grabbing on to the covers with her pussy turned up as they stayed firmly wedged into each other. Occasionally she could feel their fluid drip down.

The tension slowly released as her brother withdrew his still firm cock. Her pussy seemed to buckle and tighten to displace the empty space within. She could feel him lean in from behind her and give her a peck on the cheek before they drifted off to sleep. The storm subsided outside.
