Rain roared against the corrugated tin wall next to Rebecca's head. The churning intensity of the storm had increased over the past hour peaking in the thunderous deluge that now surrounded her. The air tasted of ozone, and the greasy stench that leeched up from the soaked ground. For her part Rebecca wrapped herself tight in her blankets, and willed herself to go to sleep. She had stoked the fire with an extra log to ensure the house would be warm for Travis when he got home. He would be soaked to the bone. Best not to think of him, and what he was facing out there. Willing herself to go to sleep, she began to sing a lullaby in her mind. The words were as familiar to her as breathing. Her mother had spent every day of her first 14 years of life singing it to her. When she died two years ago, her voice stayed in Rebecca's head. There was a sick greenish flash on the other side of Rebecca's eyelids, and the unique tin pop that followed told her that it could be only one thing.
"Rad lightning" she whispered to herself. The legacy of the bombs that had wounded the world 200 years ago, rad lightning was both terrifying and wonderful. The sky outside her little shack would be pale green, and each flash of yellow lightning would turn the world crystalline for the span of a breath. Part of her wanted to go outside and watch as the rain slacked and the sky poison set the clouds to dancing. Part of her wanted to bury itself deep in the earth, the only place safe from the radiation that could blister skin and melt the eyes that beheld it. She did neither. Instead she wrapped herself ever tighter in her scratchy wool blankets. The next pop of lightning brought a roil to her stomach, inviting her to vomit in her hands. She didn't do that either. Instead she groped blindly on the floor next to the bed. Her fingers lightly brushed against cold plastic. She closed her fingers around the little blue cylinder, and slipped it under the covers with her. After a moment of twisting, she bunched the skirt of her shift up over her hip, exposing a smooth expanse of thigh. Biting her lip, she brought the plastic canister up against her skin. She hesitated for only a moment before her thumb twitched, and the hidden needle, spring loaded, broke her skin. The narco entered her blood stream and began to spread throughout her. First her leg warmed, then her bottom. The hot syrup of the drug spread deep into her belly, and deeper into her groin. This part always made her feel like she was wetting herself. Who knew? Perhaps she was. Slowly heat crawled up her torso, under her breasts, and deep into her chest. She could feel her heart slow, her breathing deepen. Like the scalding breath of a lover it spread up her neck, relaxing her jaw, and unwinding the little muscles of her skull. Then it found her brain, and Rebecca began to not exist, at least for a little while. Another pop and quark of rad lightning tickled her stomach, but this time it felt more like the probing of a lover in the deep parts of her, than it did the urge to vomit. The canister slipped from her fingers, and she could feel herself crying and laughing at the same time.
"I poison my body with this," she said to the air, and the unyielding storm. "so I can't feel you poison me with that." As if in response the sky popped and quarked at her again. Rebecca didn't notice, for she was fast asleep.
The door to the tin shack grated open. Rebecca opened her eyes under the covers. She still felt warm and wet, half held in the high of the narco she had taken. Perhaps she had wet herself, but who cared, she felt good. She knew she should be alarmed at the sound of the door. It could be anyone coming in. it could be raiders, or traders, or Travis. They could be here to kill her, or buy her, or slip into bed with her. She didn't care, as long as she could feel like this while it happened. Travis' voice came to her through the muffle of blanket wool and brain wool.
"Caught a fox, and three big rabbits." He said. The thump that followed told her that he let something heavy fall to the floor. "Found an old dog carcass too. Not long dead, so I put the knife to it. A week's good eatin' if we are careful" His voice sounded harsh, like his throat was raw from heaving. Rebecca recalled the feeling in her stomach before the narco had taken her to this place. He didn't have chems out there. He must have gotten it pretty bad. Rebecca rolled onto her back under the covers stretching like a cat.
"There is some rad away on the table." She purred, voice silken in the depths of her high. "you should take it. You don't sound too good." The only response she got was the sound of the pills being shaken out.
"This is the last of it" Travis said, mild concern lacing his voice.
"It's ok." Rebecca told him. "I feel fine."
"Travis had always known about her love for chems, and while he may not have liked the idea of her putting chems in her body, he never complained about the way it made her feel. A knowing grunt told her that Travis knew exactly what she had been doing to survive the storm. There was no more talk left in him. She could tell by familiar sounds that he had bent to unlace his boots. There was a wet quality to the process and it confirmed her suspicion that he was indeed soaked to the bone. The long process of stripping off many layers ended in a heavy shift in the weight of the bed. Travis fussed with the sheets for a moment, and then snaked under the covers with her. His skin was wet, and his hair wetter. He, just like she, would never know if she had pissed herself, dripping as he was. Rebecca rolled back over on to her side, facing away from him as she made room on the little bed. She was immune to the cold of his skin, so she did not flinch when he pressed himself close. At first she thought he would fall straight into the arms of sleep, exhausted from his two days of hunting. Then his hand found her thigh, still bare where the needle had broken her skin. Curious fingers began to stroke along the hem, pushing it up a millimeter at a time. Travis' probing digits sought until they found the spot where she had hooked her shift in her panties. Feeling his fingers on her underwear, Rebecca knew he wouldn't stop. This thought thrilled her. She purred deep in her throat, rolling the barest increment toward him, allowing his hand better access to the front of her smooth panties. Gently his fingers traced along the front of the fabric, his rough skin snagging and tugging sheer material. Each rustle of her underwear brought a teasing thrill to everything underneath it. Her hand slipped down to cover his, and she halted his progress. His body stiffened for a moment.
"What's wrong?" he asked, voice heavy with excitement.
"I think I pissed myself earlier" She told him. The thought of it both excited her, and shamed her. "When I doped."
"That's ok." He said, pressing his body firmly against the back of her. "I don't mind. I smell like two days of road and blood. A little piss aint gonna bother me none."
Suddenly she could feel his manhood, half hard and pressed against the back of her leg, just below her ass cheek. She turned his hand loose, and he wasted no time. Given her tasset permission, his fingers slid down between her thighs. He brought his fingers to her clit with practiced ease, and applied gentle pressure through the thin fabric. Rebecca moaned, shivering as the sexual stimulation mixed with the heady swim of the drugs in her system. Time was slowed for her, allowing her to experience each nerve in her body coming to life. She had felt wet from the moment the needle had first punched into her, but this had a different quality. She could feel the slick moisture of arousal beneath Travis' fingers. Travis shifted behind her, and his now stiff member slid along the back of her leg. With a satisfying thump it came to rest along the crack of her ass. The head of him was nuzzled just between the tops of her thighs, held against her panties by its own rigidity. Suddenly his hand spread wide across the front of Rebecca's hips, and the tip of him pushed slowly between her legs. She lived in every moment of it, the drug allowing her to focus on the trek his cock was taking. Slowly he pushed between her legs. First his tip pressed firmly against her slit, then his shaft rested comfortably there. She squeezed her legs tight, keeping firm contact with his rigid pole. Travis' hips began to pump behind her, pulling the tip of him back and forth. When he pulled back the ridge of him would bump against her clit, halting firmly against her entrance, held in check by only her tight panties. When he would thrust forward, his head again would electrify her clit, then the shaft would drag along the slit of her. Each thrust would end with the tip of his cock peeking meekly out from between her thighs. Rebecca reached behind her gripping Travis' hips. She willed him to push harder, be rougher with her. She could feel quivers building inside of her. Excitement joined raw lust, at the thought that this might be the time. Travis, encouraged, was thrusting hard and fast. Her thighs and quim and underwear were becoming a sloppy mess of arousal. She relished his hot breath between her shoulder blades as she thrust back with equal need. Then the trusting stopped. Clumsy fingers groped between her thighs from behind. Rebecca could feel her panties being pulled to the side, Travis' tip probing to enter her. Forcing herself, Rebecca slid a hand into the ruin that was her sex slick crotch. She blocked his entrance and said
"No!"
"Please!" Travis whispered, almost whimpering behind her. "
No." She said again, gentler this time.
"But why?" Travis asked sounding defeated.
You know why Travis." She began, launching into a conversation they had had many times before. "We are brother and sister, and bein' twins we is closer than most. You know what momma used to say about babies born o' those as close as us. They come out with all sorta problems. Add to that you got a good dose of radiation out there,"
"But I took the drugs." He protested, interrupting her.
And I didn't." She said with finality. That seemed to quell him. His fingers, slower now, slipped her panties back into place over her sex.
Will you still let me," He trailed off.
"Of course I will." She said, tucking his manhood firmly between her thighs, and tight against her now clothed sex. One of his heavy hands slithered around her body, his fingers grasping her throat in a gentle but firm squeeze. The other grasped her breast roughly, thrilling her to the core. Rebecca was substantially smaller in frame than her twin brother. He could twine himself around her like a coiling snake, choking her air and controlling her every move. It aroused something deep and savage in her mind and other places when she was handled roughly, used for the pleasure of her user. In times like these she was so much like the drugs she more often turned to, pleasure to feed the need of the addict. Travis drove himself between her thighs with the fervor of the religious. His cock roared against her sex once more building a quivering tumult inside of her. Her loins once again were soaked in hot unrepentant desire. She felt herself approaching her edge. This had never happened before. Not with Travis. She had cum many times in her life, but never had it been at his hands. Always it was in the dark places, alone and needful that her own touch had sent her to that screaming and shuddering place of release. Now she was there, at the touch of her one companion in life. Finally he would take her over the edge. Just then there was a break in the rhythm. Travis' hand tightened around her throat and on her breast, pushing her even closer, but not over her edge.
"I'm gonna!" Travis grated against the back of her neck.
"No! Wait! Just a bit more!" she whimpered. Her words where choked off by the intoxicating hand on her throat. Then there was an eruption. Hot cum burst out between her thighs. Jet after jet of rampant release pressed hot against her panties, and barely covered sex. She was so close to her own climax she practically growled in lust. She tried to grind herself against his still spurting head, but his grip, like iron, held her firm and motionless. Still he was cumming, and still she was so close. There was nothing she could do but hold still forced to live his release while she was denied her own.
Then the flow stemmed, and the rough spasms stopped. Travis removed his cock with efficiency, and Rebecca could feel herself retreating from the orgasmic edge. Hurriedly, gagging with need for some kind of release she groped once more next to her bed. Her hands fell on one of the unused narco canisters. Desperately clinging to the edge of her orgasm, she rammed the canister against her neck. She had heard that dosing in the neck was a feeling better than sex. She had never tried it, but now, in her moment of desperation she needed raw pleasure more than life itself. The dose was strong, and so close to her last that she worried she may never wake from it again. It was amazing. Instantly intense heat settled behind her eyes and time slowed to a crawl. Warmth traced down the large veins of her neck, spiraling into her chest. Her nipples seemed to glow with the kisses of a thousand lovers. The chem crawled still further, liquid fire in her belly. Then it reached her intended target. Lightning settled in her center roiling like the storm that passed. She spasmed hard, breath slammed out of her, as she doubled over. There was a wave of euphoria as the universe penetrated her just were she needed it most. Then the dams burst. There was a gush of hot liquid between her thighs. A storm torrent of hot moisture, to accompany the lightning in her sex, soaked the bed under her. Over and over she shuddered. She gagged with the relief of the moment. Her hands twisted in and ripped the fabric of her thin shift. Her nipples were like knives and sensitive to every shift and shiver of blanket and air. Still the core of her emptied. Still she shook and came. A universe exploded inside of her mind as she exploded on the sheets. Her brother's cum mingled with her own as one last groaning heave emptied her essence completely into the cotton and wool twisted around her body. Then she fell still. Her body, lead heavy, sank deep into the blankets. She could feel her heart, thrilling only moments ago, slowing. Gently consciousness reseeded from her. Just before she lost the world, she whispered to Travis, who had fallen into exhausted sleep even as she was cumming next to him.
"I think I may have pissed myself again." She said, listening to her tiny voice against the howling wind of the wasteland. "It was so good. I feel so good." With that, she slept.
