It was the second time that the power had gone out. The night that he had nearly told her about his discovery. He now knew he shouldn't have taken his brother's advice. But when he asked Marty thought Troy, his older brother, was usually right about most things. And after he and Crystal had tried to get pregnant for over six months, he had confided in Troy. Troy had two kids himself, with his now ex-wife Betty, so maybe Marty thought he was some expert. Troy had just told him. "Man go to the doctor and get them to run a test and find out. If it's got something to do with you, then you can tell her and save Crystal all this heartache."

That is what convinced Marty to go. He had, since he had started dating his wife, this unquenchable desire to give her everything she ever wanted. It had driven his mother crazy when they dated. Now, his desire had him stuck.

He had listened to his brothers advice. Snuck off and got himself tested and the doctor had confirmed his fears. He was sterile. A case of the measles when he was a child probably the culprit. He had meant to tell her then, but he tried to pretend the doctor was wrong. A month later and still no pregnancy and he knew he had to tell her, but he didn't want to admit it to himself, much less to Crystal.

For the first time he was not going to be able to give her what she wanted. And the only person at fault was himself. The person who had always given her everything, couldn't give her the very thing she so longed to be. He didn't know what to do.

Until the night the power went out on their street for the second time in less than a month. They had been in the middle of dinner the first night and had finished by candlelight, the next night Crystal had been in the shower and had needed help. Both nights had led to them having wild, hot sex. And on that second night, right after she had drained his infertile balls, he had come up with the idea to give her what she wanted. It wasn't a plan he wanted to execute, but one that he knew he would need to do if he were to make his wife what she always wanted to be, a mother.

So now, one month later, the plan was coming into fruition.

In the moonlit bedroom, Crystal lay nestled under the covers, her bare shoulders exposed to the cool night air. It was 1975, and the suburban home she shared with her husband, Marty, was bathed in the soft glow of the moon filtering through the french doors of the bedroom. She had removed her glasses hours ago, leaving her vision blurred, but she didn't need them to feel the warmth of the man beside her. She traced along the bed and realized that her husband was gone. The warming sheets, the only clue of his absence. She leaned up and shifted to the lamp to turn it on as the house was uncharacteristically dark. The lamp wouldn't come on and then she noticed that the alarm clock was off too. "Another power outage," she said to herself.

Marty had slipped out of bed as soon as he knew Crystal was asleep, his heart heavy with the secret he couldn't bear to share. He had devised this plan, a desperate, humiliating plan, to ensure she could have what she had always wanted. He'd enlisted the help of his brother, Troy. The one who had gotten him into this mess. He had thought to ask his younger brother, Rusty, but since Rusty didn't have kids of his own yet and he had also had the measles when they were younger, Marty had decided on Troy. Troy was only one year his senior and although nothing like Marty in personality the two shared a slightly similar build and had voices that were similar enough that even their mother couldn't recognize them apart over the phone.

So as Marty had planned, he had stolen out of his bed to stage a power outage, plunging the house into darkness at the breaker box in the garage. It was here that Troy was supposed to meet him. Troy was parked down the street and was waiting on the lights to go out to come up the drive. Marty could see his silhouette slowly coming down the gravel driveway.

Marty thought back to asking Troy. He had met him for lunch on a Saturday and Troy had refused. Told Marty it was the dumbest idea he had ever heard and all but stormed out of the restaurant. Marty knew that Troy was no angel, but he knew enough about his older brother to know that he had a twisted moral code that Marty was pushing the limits on during the conversation. It had taken two more conversations for Troy to even consider it, and Marty truly believed it was the thought of him asking Rusty that truly convinced Troy. They both knew their wayward younger brother would say yes, and that the chances of Crystal discovering it were far greater with their more muscular and shorter brother.

So here they were, Marty having left his unknowing wife in bed, while he quietly retreated to the garage, leaving Troy to take his place. The arrangement was clear: Troy would impregnate Crystal, but she would never know it wasn't her husband. Troy didn't say anything as he came up. Marty looked up at him. "I left her asleep. Did you put on the boxers I bought you?"

"Yes," Troy said exasperated. "I don't know why you are worrying over details. There isn't going to be any light in that room to see a darn thing." Troy slipped out of his cut off jean shorts and took off the tanktop he had worn over, so that now he was in the same boxers his brother was sporting in the garage. Troy had even gotten a shorter haircut yesterday, so that even that couldn't be a clue to Crystal. "Anything else I need to know?" he asked.

Marty shook his head "no", and watched as Troy opened the screen door and entered into the home that he shared with his wife. Marty thought back to Troy's comment and he chuckled to himself. He wondered if Troy was upset that there wouldn't be any light in the room. He figured that Troy wanted to get a good look at his gorgeous wife. Her breast even covered in a shirt got a lot of attention, and even though Troy would never admit it, he knew he had probably ogled her a time or two himself. He was glad it would be too dark for Troy to see her, but as he looked across the moonlit backyard he didn't' feel as confident. He suddenly remembered the glass paned french doors beside his bed, which were free of any coverings and his past experience on a full moon night told him that the visibility was probably going to be more than he had anticipated. Fear clutched at him. Maybe he had made a mistake. There was a chance that she would be able to see him. What if she had gotten up while he was away. She had been asleep, but she could have gotten up, found a match or something.

Marty's guilt and worry gnawed at him as he stood in the garage, the cold concrete floor beneath his bare feet. He tried sitting down. He had pulled out a folding beach chair from the supply closet for that very thing. The lights were out and it was nearing 2am. But his anxiety got the best of him. Was this what he wanted? "No!" the answer quickly came to his mind, but it was what he needed to make sure that Crystal got her baby. He just hoped that the one time would take.

He couldn't stay here, though. He stood from the beach chair he'd pulled out to wait out the night. But now he knew, he had an overwhelming need to witness what was happening, to make sure that their plans were going through. To make sure that Crystal was none the wiser to what was happening. Just one peek Marty told himself.

Troy had one shot to give her what she most desperately needed, which he could never give. The thought of that was too overwhelming.

Marty crept from the garage and around to the backyard, his footsteps silent on the dewy grass. The blinds were down and closed, but a broken panel allowed him an unobstructed view of the bedroom. He had left the window cracked, knowing how hot the room got when the power went out. At the time, he had not planned to come and watch, but to make sure that the room got a breeze when he turned off the power. Now, he pressed his face against the bedroom window, the glass cool against his skin. Inside, the room was dark, but the moonlight from the curtainless french doors cast just enough illumination for him to see the silhouette of Troy climbing into bed beside Crystal. His heart sank as he watched Troy's broad frame settle next to her, his brother's muscular build a similar, but also stark contrast, to his own more lean physique.

Crystal stirred, her hand reaching out instinctively. "Marty?" she murmured, her voice thick with worry.

"Yeah, babe," Troy replied, his deep voice mimicking Marty's tone as best he could. "Go back to sleep."

"I wasn't asleep. I woke up and couldn't find you and then I realized the power was out."

"Yeah, it woke me up when it went out. I got up to check." Troy was talking too much. Marty knew their voices were similar, but not enough alike that he should be talking this much. Marty's mouth was dry. Was Crystal going to pick up on it?

"This is the third time in less than two months." Crystal said.

"I like the dark," Troy said again. Marty flinched at the sound of his brother's voice. Crystal chuckled and turned so that he body was facing what she thought was her husband. Troy moved closer to Crystal. Their bodies only inches away as he settled the sheets over himself.

They grew silent for a moment and Marty's eyes were adjusting more to the dark. He saw Crystal reach up and touch Troy's face, thinking it was her husband. He watched as Crystal's hand found Troy's chest, her fingers tracing the contours of his bare chest. She sighed softly, her movements slow and sensual. "You feel different tonight," she whispered.

Marty's heart stopped. Was this it, was this when she realized her husband's betrayal? Troy was more muscular, his chest had more hair, but would she notice. Marty's mind spiraled.

Troy's lips curved into a smirk, though Crystal couldn't see it. He didn't know why, but he liked the fact that Crystal recognized the differences between him and his brother, even if they were not enough for her to know that they were two different people. He kept silent and slowly moved in and found her lips. Troy had never wanted to admit this to anyone, especially his brother, but he had always lusted after his curvy sister-in-law.

Marty's stomach churned as he watched Crystal's hand wrap around Troy's neck. Troy was up on his elbow, she lying flat beneath him. Troy was leaning over her, his face to hers, their mouths together in a sensual kiss. Then he saw Troy lay back, moving away from her to lie flat on his back. Marty's mind couldn't understand. What was he doing? Why wasn't he doing what he came here for? Why not just slip it in while they were kissing, pump a few times and be done. I mean, that is what he would have done on a normal night.

But then he saw Crystal. She moved closer to Troy, first snuggling into the crevice of his arm, where she traced her fingers across his chest, and then before Marty could even blink she was now up on her elbow looking down at him in the light. Marty worried that her sudden movement spoke that she had recognized a difference, but then she lowered her lips to Troy's chest kissing him. Troy's hand traced the length of her arm, a soft touch, one that Marty often gave her.

Crystal in her nightgown, suddenly sat up and discarded the gown. Exposing her round breast to Troy. The light was more illuminating than Marty had imaged and he knew his brother was soaking up every inch of her bare skin. Troy's hand raised and traced in a fine circle her left breast his thumb lightly brushing across her nipple. He heard her breath out, heavy and lustful. Then she flipped down the covers. Troy lay beneath in the boxers.

Marty watched as Crystal's hand traced across Troy's flat stomach. Troy reached his hand down and pulled the waistband of his boxers down and then off, discarding them to the floor beside her discarded gown. Crystal's hands were on him as he lay back, tracing his muscles, retracing her path down his stomach until she slid lower and gripped his cock. He suddenly saw it in her hand, and his heart lurched. The size of it was wrong. It was so much more than what he was packing.

Troy had never been more turned on in his life. Was it the forbiddenness of this or just the utter sexiness of his sister-in-law? He didn't know, but his prick was as hard as a teenage boy's on prom night. He looked up when Crystal took off her gown and he probably could have cum just from the sight, and when she had pulled back the covers, he couldn't wait anymore. He had shed those boxers as fast as he could. What he hadn't expected was for the minx to take charge as soon as he leaned back, and when she had grasped his shaft and began to pump, he nearly lost it. God, she was sexy.

In Crystal's hand Marty could tell his brother's cock was thicker, longer than his own, and the realization stabbed at his pride. He'd always been self-conscious about his size, and now, seeing Troy's superiority in Crystal's hands, he felt utterly inadequate.

"Mmm," Crystal hummed, her fingers stroking Troy's length. "You're bigger tonight. What's going on?" Troy couldn't help that a shit eating grin suddenly painted his face. He had figured that he and Marty, who were so similar in body size would have similar size pricks, but her words helped him realize they weren't. And he was the bigger. He couldn't help that this brought a serious satisfaction to his ego.

Troy chuckled softly, the sound grating against Marty's nerves. "It's you babe," he said, using the term of endearment that Marty often used. "He's just happier to see you than usual."

"It's the biggest it has ever been," Crystal replied. The confirmation for Troy that he was bigger than his brother brought another thrill to him and he felt his prick jump in Crystal's petite hand.

Crystal's laughter was soft, her body relaxing into the bed. "Well, I'm happy to see him too," she said, her voice playful. He watched as she stroked it. "Man, you feel so hard tonight." Her voice was husky with lust. "Maybe since he's so happy to see me, he needs a special treat." Before Marty could process her words, she leaned forward, her lips parting as she took Troy into her mouth. Marty heard Troy's intake of breath as her mouth enveloped first the head and then down his shaft.

Troy couldn't believe what was happening. Marty had told him before that Crystal completely refused to give him a blow job, even though he had begged for years for one. And now, here she was opening up her luscious lips to take him in. He knew that he was going to have to hold back or he could ruin what he was here for, but the feeling of her lips as they slurped away at his prick. And the thought that all of this was because he was bigger than her husband, or seemed bigger than her husband usually was, was almost too much for him. He felt like he was on edge, but he wasn't going to push her away. Not from her first blow job.

Marty's breath caught in his throat as he watched Crystal begin to deepthroat his brother. How did she even know how to do that? Her head moved rhythmically, her hands gripping Troy's hips as she sucked him with a fervor he'd never experienced. This was new--Crystal had never been one for oral sex, always claiming it wasn't her thing. But now, with Troy, she seemed eager, her enthusiasm undeniable. One of her hands crept to his balls and she began to move her head down coming off his shaft to nuzzle at his balls.

"Fuck, Crystal," Troy groaned, his hands tangling in her hair. "You're amazing."

Marty's chest tightened as he heard the raw desire in Troy's voice. He wondered if his brother was relishing the moment, savoring the power he held over both Marty and Crystal. The humiliation was almost too much to bear, but Marty couldn't look away. It felt like an eternity. She was really giving it to him. The gluck, gluck of her mouth and his heavy breathing. Marty had not signed up for this. Anger rose in him. She wouldn't get pregnant this way. He couldn't believe that Troy had let this happen.

Then as if reading his mind, he saw Troy motion for her to stop. Crystal pulled back, her lips glistening as she smiled up at Troy. "My turn," she said, her voice sultry. She shifted onto her back, her legs spreading invitingly. "Come here."

Troy didn't hesitate, his body moving with a confidence Marty had never possessed. He positioned himself between Crystal's thighs, and then he dove in. He devoured her. His tongue licking between every fold. Troy could taste and smell the desire in his sister-in-law and he wanted to answer her longing. He found her nub and began to flick his tongue faster there as he entered her with two fingers. He lavished her slit with long and deliberate strokes of his tongue. She moaned beneath him. He couldn't take it anymore. He knew he had to have her. He had not expected his brother's proposition to play out like this, but he was so glad it had.

Troy stood up and slid her to the edge of the bed. Her hips hung over the side. His hands gripped her hips as he entered her with a single, smooth thrust. That took her breath away. She pawed at the sheets beside her as he stood silent, his cock buried to the hilt inside of her. He had never felt anything so tight, anything so wet. He let her adjust to him.

Marty's vision blurred as he watched Troy fill Crystal, the man's size stretching her in a way he never could. He heard her sharp intake of breath, followed by a soft moan of pleasure. "Oh, Marty," she whispered, her hands clutching the sheets. "That feels so good. You feel so much deeper."

The name on her lips was his, but the body inside her was Troy's. The irony was unbearable, and Marty's guilt deepened with every slow agonizing stroke of his brother. He watched as Troy continued to move, his strokes slow and deliberate, his hips grinding with a rhythm that soon had Crystal arching beneath him.

"Yes," she gasped, her nails digging into the sheets. "Right there. Oh, that's it." Crystal had never been vocal with him. Always a quiet mouse in the sheets, but now after only three or four strokes she was expressing her pleasure in ways he had never heard. "Oh God, Marty, you have never touched me there." Her voice was shrill with excitement, dripping with pleasure.

Troy had never been so turned on in his life. His cock was bringing her to life, as she vehemently expressed her pleasure with this new prick that was reaching places her pussy had never felt. God, she just thought that this was Marty super turned on, she had no clue this was her brother-in-law riding her. No idea this was her brother-in-law with a prick bigger than her husband's giving her pleasure like she had never felt. Troy was beside himself and he could feel his balls beginning to tighten. That he had lasted this long through all of this was a fete for a king.

Marty's jaw clenched as he heard the lust in her voice, the way she responded to Troy's touch. He'd never made her feel this way, never elicited such raw, unbridled passion. The realization was a knife to his ego, and he felt himself sinking. A slow spiral of doubt gripping his thoughts to plunge him into blackness.

Crystal's moans grew louder, her body tensing as her first orgasm approached. "Don't stop," she pleaded, her voice desperate. "Oh God, don't stop. Don't stop. Marty. Oh fuck, Marty. That is too much. I am...I am going. I am going to..." and then she was blabbering, words that neither Troy nor Marty could understand.

Troy grunted, his pace quickening as he drove into her with a ferocity that left Marty breathless. He watched as Crystal's body shook, her cries filling the room as she climaxed, her walls clenching tightly around Troy's cock. He knew without a doubt that she had never had an orgasm with him so powerful and his heart sank.

Troy roared out his own climax, but to his astonishment his prick stayed hard. God, what was this woman doing to him? He had never felt this turned on.
