"You must be the one with the lame husband," he said as Jennifer opened the door.

"That's me," she responded, taken aback by his abruptness and shocked by her own answer. She quickly composed herself. "Thanks for coming. I'm Jennifer." She reached out to shake his hand, without thinking how silly the formality was given the evening's agenda.

"Thanks for having me," he said. He grabbed her hand and moved it to his lips. "I'm Sam." He smiled as their eyes met. He gave the top of her hand a quick kiss.

He quickly looked her up and down and it was clear that he liked what he saw. Her flowery sundress showed an alluring amount of tasteful cleavage. At 24, her skin glowed with youthful radiance.

"Please, come in," Jennifer said. He entered the house and followed her through the hallway to the living room.

At just over 6', he was a little taller than she had imagined from his online profile. He looked younger than 30, but it was evident -- if only by the way he carried himself -- that he was a few years older than her husband.

James was in the living room, waiting for them.

"And you must be the husband," Sam said. He walked confidently over to James, who nervously rose to his feet. Sam shook his hand firmly. "You have a lovely home... and a beautiful wife," Sam said, glancing towards Jennifer. She smiled, but James was extremely nervous -- and that showed on his face.

* * *

James and Jennifer had gotten married the year she had graduated from college. James had graduated the year earlier and gotten a good, if boring, job at an office in the city. They lived comfortably, but sometimes she thought that maybe she had missed out some youthful adventures. Still, she had always wanted a family, and James represented stability, so she never thought too much of it. Besides, James doted on her every need. He adored her, and would do anything to make her happy.

She and James were trying for a baby, something Jennifer wanted very badly, but hadn't yet been able to conceive. To make it worse, Jennifer's friends knew she was trying. When they weren't talking about their own flings and boyfriends, they were asking her about their progress. One of her friends had even drunkenly asked her, "What's the matter? Can't James pump a baby inside you?"

In truth, it had only been a couple of months. But Jennifer knew women who had gotten pregnant without trying and she was growing more frustrated by the day. What's more, fertility counseling was way too expensive for their budget.

Of course, when Jennifer first mentioned to James the idea of another man, she didn't mention their efforts to expand their family. She simply wanted variety, she said, and thought this would be a good way to mix it up. She didn't want a threesome, she explained, but he could be there to watch if he really wanted to be.

James was a little surprised -- and more than a little hurt -- but he ultimately agreed. She never had any doubts he would end up going along with her plan; after all, he always did. She sat down and posted the personal ad that very night.

The two men sat down on the couch. Jennifer sat in between them, holding her husband's hand.

"Well... First... there are a few things I want to go over," James stammered.

Sam leaned forward and quickly interrupted. His annoyance was apparent in his dismissive tone. "Sorry, that's not how it works. Only the two of us get to make the rules." Sam placed his hand on Jennifer's leg, several inches above her knee. "That's it. If you wanted to make the rules, you should have given your hot little wife what she needs." He gently squeezed her thigh and stroked her soft, smooth skin.

Sam continued. "My only rule is this: you don't get in our way."

Sam's confidence struck something in Jennifer, and she instinctively parted her legs. Her right hand was still grasping her husband's left hand, but she slid her left hand to rest on Sam's knee.

James couldn't believe his ears or his eyes. This man, in his house, was groping his wife -- and telling him that he couldn't do anything about it. "This is what she wants," he told himself, trying to calm himself down. "She'll realize what a mistake this is. This is bad, but it’ll be over after tonight."

Sam moved his hand from Jennifer's leg to around her shoulder. He gently tugged her closer, and, without thinking, she turned her head to meet him in a kiss. His hand moved to cup her cheek.

"Time for us to take this somewhere else," Sam told Jennifer. She quickly let go of her husband's hand and got on her feet. Jennifer guided Sam to their bedroom.

James followed them and sat in a chair a few feet from the bed. He watched as Sam kissed her neck, and he could hear her soft moans as Jennifer reacted to the warmth of his breath on her skin.

"My God, this is really happening," she thought to herself. She felt Sam reach behind her shoulder blades to unzip her dress. He continued to kiss her neck and then traced kisses to the top her chest.

"Wow, these are fantastic," Sam said of her breasts. His hands moved underneath to gently cup her supple flesh. His thumbs brushed her nipples. They hardened immediately.

Her dress was quickly on the floor, followed by her underwear. She sat on the bed and unfastened Sam's pants. She couldn't help but show a grin on her face when she took Sam's thickening member into her hands -- she hadn't ever seen anything like it.

"Don't worry, I'll be gentle," Sam said. "I know you aren't used to real cocks."

Both of them naked, Sam kissed Jennifer's lips and gently guided her on to her back on the bed. His hands glided over her body, down between her legs. He felt her warmth and wetness -- her excitement was evident.

"Oh, I almost forgot!" Jennifer said with a start. She reached into the bedstand, pulled out a condom, and rolled it on to Sam's member.

James watched helplessly from his chair. He didn't want to see this, but he desperately wanted to be there for his wife, in case anything went wrong. Yet, even from several feet away, he could see how wet his wife had become, and the look of sexual desire in her eyes was one he hadn't seen since the two had met in college -- if she'd ever looked at him that way at all.

He watched, transfixed, as his wife lay on the bed with her legs spread wide. With her right hand, she gently grasped Sam's cock and guided it to the hungry entrance of her pussy.

Sam paused for a moment, only dipping the tip of his encased tool between her slippery lower lips. But Jennifer was in no mood for waiting. She grasped his hips, eagerly pulling his whole length inside her.

"Mmm, your pussy is way too nice to be wasted on your husband," Sam said, smiling. He could sense James squirming in his chair just a few feet away. Jennifer's eyes widened as Sam's girth slid between her labia. "Damn, you feel like you've never been fucked," Sam continued, "but we're going to change that right now, aren't we?"

Sam withdrew his member from her pussy, suddenly leaving Jennifer with an empty feeling between her legs. She immediately let out a whimper.

"Tell me you want this dick. Tell your husband, too." Sam knew what Jennifer's body wanted, and he was now in control.

"Yes. God, I want that dick. Fuck me, Sam. I need it." Jennifer's words surprised even herself. Sam smiled, knowing that any concern Jennifer had for her husband's feelings was now gone.

The condom was coated in her slick natural juices, so his dick easily slid into Jennifer's hungry hole. Sam's back bent over her body as he pumped slowly and kissed her neck. Before long, he arched his back and increased his speed.

James desperately wanted to stop watching his wife's tits bounce with each thrust from another man, but he couldn't look away. His thoughts raced. He went into denial. "This is going too far... There's no way this is what she wants."

Finally, James found the courage to raise his voice. "Baby... Jenn... are you okay?" His question went unanswered, except by the enthusiastic moans that emerged from his bride's mouth with each thrust of Sam's hips.

Sam also ignored the husband's question, but he didn't miss the opportunity to show him who was in charge. "Is that what you like? Is that what you can't get from your husband?"

"God, Sam, yes... fuck me... fuck me like that," she gasped. "He never fucks me like that." Sam's rock-hard tool was probing depths of her wet hole that had never been explored before. He slowed his pace, lifting her legs to give himself -- and Jennifer's increasingly distraught husband -- a better view of his cock disappearing deep into her welcoming slit.

Sam was in full control of both them now, and he knew it. Jennifer was in ecstasy, her first orgasm imminent. James now had his head buried in his hands.

It was then Sam felt the tell-tale pop of a condom succumbing to the relentless pressure of a good pounding. The mushroom head of his cock felt magical against the bare, slippery walls of Jennifer's warm pussy. But after a few deep strokes of unprotected pleasure, he paused to pull the shreds of latex off his dick.

It didn't take long for James to realize what had happened. "Oh my god! It's her most fertile time of the month," the panicking husband said, fear rising in his voice. "You didn't cum in her, did you?"

Sam looked at him. "You have nothing to worry about. But unless you have another one, I guess we'll just have to do this the old-fashioned way." He stroked his bare dick a couple times reinserted himself into Jennifer’s soaking wet hole. The two quickly reestablished their rhythm; the sound of Sam’s thick rod deep into Jennifer’s now-unprotected, married cunt filled the room.

James was apoplectic. "You have to stop." He was now standing, watching his wife fuck a stranger bareback. "I can't fucking believe this." Jennifer and James ignored him as he stormed out of the room.

The two lovers were relieved to be rid of him, and were now free to concentrate on each other. Sam pounded Jennifer harder, and she felt his balls slap against her asshole with each thrust.

“Yes, oh yes! Fuuck!” Jennifer was cumming, and her pussy clenched down on Sam’s bare cock.

"Mmm, baby, you're going to make me cum." Sam grunted, with one hand on her shoulder and another full of her right breast. He slowed his rhythm, and prepared to withdraw his member from her before it was too late.

Jennifer woke from her orgasmic trance. She wrapped her legs around her lover, pulling him deep inside her. Her voice was soft, almost meek: "Don't pull out, baby. Give me your cum."

"You want me to finish inside you?" Even the always-cocky Sam was surprised to hear that from another man's wife -- especially since this was their first time together.

Jennifer grew more strident, more serious. "Fill me, baby. Give me your seed. Make me yours."

She looked him the eyes. "Give me your baby," she urged. “Please.”

Sam wasn't about to argue. He pushed inside her, grinding his hips into hers and pushing the head of his cock right up against her cervix. He withdrew almost completely before plunging in again. On the third stroke, he reached the point of no return.

"Oh, shit," Sam groaned. "Fuck, baby. Yes! I'm... I'm cumming!"

"Yes! Give it to me," she whispered into his ear, kissing his neck and sucking on his earlobe. She was ecstatic. Everything she wanted was about to be hers.

Sam unleashed a torrent of hot cum towards Jennifer's receptive, fertile womb. She felt the first warm jet of his seed splash against her cervix, followed by two more. His slick wetness filled her cunt to the brim, soaking Sam’s cock in his own live-giving juices.

“I’m yours now,” Jennifer said. She knew Sam’s seed was well on its way to finding her fertile egg.

Sam could only smile. He withdrew his twitching member from her and met her in a tender kiss.

James had heard them moan together in ecstasy from the other room. "At least it's over," he thought. He collected himself and entered the bedroom.

To his horror, he walked in to see the two them embracing and sharing a tender kiss. What’s worse, Sam’s semen was leaking from his wife's still-quivering pussy.

"Don't worry, there's still plenty left in there," Sam told James, sensing his horror. "Your wife really drained my balls tonight."

Jennifer was still in heaven. She didn't want to move; she was desperately trying to keep as much of Sam's seed inside her as possible. She kept her knees up, knowing her cervix was dipped into the seminal pool that Sam had freshly deposited deep inside her.

Sam broke their kiss. "Thanks, sweetheart, you're really something,” he said as he turned to leave.

"Oh, we're not done here," Jennifer responded quickly. "You're going to stay the night and give me a top off tomorrow morning, just to make sure I'm pregnant." She paused. "That is, if that's alright with you."

She wasn't addressing her words to her husband. She was looking right at Sam.

Sam laid back down beside her, where her husband had slept next to her for many years. "I'm at your service," Sam replied.
