“Wife” Swap: Gender Swap Stories

“They should be here by now,” Laura said, glancing out of the window. “You don’t think they chickened out on us, do you?”

Mark sat at the dining room table, his hand on a glass of whiskey. “Rick said they were coming. He was the one a little freaked out by the idea, not Carrie.”

The smell of sizzling meat drifted in from the kitchen. Laura tutted as she went to check on dinner. Mark took another drink and compulsively ran his hand up and down his thigh. Moments later, Laura returned. “No, you’re right. Carrie had the idea in the first place. How about you? Are you still ok with it?”

Mark’s eyes rolled wildly, spiraling to focus on different points around the room. “I mean, as much as I can be. We’ve talked about it. I’m pretty freaked out, I won’t lie. I’m afraid everything will be normal tonight and then tomorrow we won’t look at each other the same.”

Laura touched his shoulder and kissed the top of his head, “I love you more than anything. Nothing that happens tonight will change that.”

“And what if you like Rick more? Shit, what if I like Carrie more.”

“Then I’ll have to do my best to convince you that I’m better.”

A pair of headlights flashed in the driveway. The couple went silent, holding their breath. Two car doors slammed. Voices spoke outside, audible but soft throught the windows. Mark downed the rest of his drink. “Well, here we go.”

Mark led the way to the foyer. They waited until the guests knocked. Mark almost opened it immediately, but his wife hissed at him to wait a few seconds. After a brief period of frantic pantomime, Mark pulled open the front door. Both parties exclaimed greetings, but neither moved to come in or to step aside. The two couples looked fairly similar. Both of the men were tall and broad chested with lanky arms and narrow faces. The women were of comparable height to their husbands at five foot eleven in flats. Laura had dark auburn hair while Carrie’s leaned toward a darker shade of red. While the men had opted for generic blue button ups and jeans, the women chose brightly colored sweaters. Rick held a bottle of wine while Carrie had a casserole dish. “So, can we come in?” they asked in unison as they handed over their dinner contributions.

“Oh, yeah, come on. Mark get out of the way,” Laura nudged him. “Ooo, this looks good, what is it. Come on to the kitchen.” She waved for Carrie to follow her. “Rick, make Mark get you a drink.”

Carrie stopped for just a moment, “Hey, Mark.” She gave him a light hug. Mark, all too nervous about the situation, kept his eyes on Rick while being keenly aware of the other man’s wife pushing her breasts into his chest. It lasted only a moment before she pulled away, taking the wine from her husband, but Mark could still smell her perfume in the air. Both men watched the women leave, each anxiously watching the swaying bottoms of their wives. Mark closed the door and waved for Rick to follow him.

The two men went into the living room and over to the small bar. Mark poured two new glasses and handed one over to his friend. “So….what’s up?”

Rick grinned, “Shit man, I don’t know. This is weird right?”

“Fuck yeah, it’s weird.”

“Carrie is really gung-ho about it, though,” Rick said, after a long drink. “I mean, even that sounds bad. It’s not like she’s specifically excited about the idea of fucking….you. Sorry, that sounds bad.”

Mark, actually a little insulted but prepared for a lot of that throughout the evening, responded, “No, I get it. Laura’s been the same. She goes on about how this will really build up our relationship and make it stronger. She says she’s excited to you know…watch me with another woman.” He punctuated his sentence with a drink. “We don’t have to do it though. Not too late to call this whole thing off and go back to being normal.”

“I think it might be a little too late, don’t you? But hey, lot of drinking and stuff to go before we get there. Let’s try not to think about it. That’s Carrie’s advice anyway. The whole week she’s been trying to coach me. I swear she’s terrified that I’m gonna cum immediately or not be able to get it up at all.”

Mark laughed. “They’ve been swapping notes or something. I think they’ve gotten on some kind of couple swapping forum. Oh, that reminds me, did you see that post about the new patch?”

Their conversation drifted to more comfortable topics of video games and sports. They both continued to drink, and the alcohol began to at least dull their nerves. Meanwhile, the girls chattered and laughed in the kitchen. Their seeming comfort with the evening did little to assuage the guys’ apprehension. Mark turned on the television and flicked it over to a baseball game. The two men pulled out their phones and mindlessly tapped at the screens while their minds wandered to the one topic they wanted to avoid. Finally, as the silent tension began to mount once again, Carrie summoned them to the dining room.

“Everything looks delicious, Laura,” Rick said as he settled into his seat. Both he and Mark cringed slightly at the unintentionally loaded statement. Before them, the women had spread a beautiful meal of pork tenderloin, russet potatoes, a light salad, and fresh baked bread. Somewhat out of step with the rest of the table was Carrie’s casserole. It seemed to be composed primarily of cheese and noodles. The top of it bubbled slightly from being heated in the microwave. Rick saw Mark eying it suspiciously. “Oh, don’t worry. Looks bland, but her cheese casserole tastes amazing.”

Carrie playfully slapped her husband’s shoulder. “It’s not a ‘cheese casserole.’ It’s sort of like chicken spaghetti, but with different kinds of cheese….and no chicken, but breading. So like a really cheesy dressing.” She ladled out huge servings for herself and Rick.

“I’m sure it’s wonderful,” Mark said politely. He scooped out a small portion for himself, but Laura, who had been zipping around refilling glasses, took the dish from him and gave him a second scoop. Mark looked up at her in protest, but she returned a look that indicated he shouldn’t be rude. Sure, I wouldn’t want to insult her casserole if I intend to fuck her later, he thought bitterly. “Well, go on then, no sense in just looking at it.” He tried to inject as much cheerfulness into his tone as he could.

Laura finally took her seat beside him, pouring the last bit of the wine into her glass. “Don’t worry, we have two more bottles,” she said to Carrie. “So, what were you two talking about?” She asked the question with a devious smile.

“Nothing mostly,” Rick answered. “Guys can do that. We don’t have to be constantly talking when we’re around one another.”

“Yes, stoicism is one of the best traits of men in women’s eyes,” his wife added. “Every women wishes she had a man who sat around and said nothing, never communicating his thoughts about anything. Frankly, I wish you’d shut up most of the time.” She leaned over and kissed his cheek. Nothing about the gesture was unusual. Mark and Laura had watched Carrie peck her husband on the cheek hundreds of times before. This was different. The whole room grew more aware of their bodies as she pulled away. She cleared her throat, “So, Mark, how’s work?”

Happy to move the conversation away from the awkward moment, Mark lapsed into discussing his latest project. Though he tried to remain bashful about his work, he could never resist when people prodded him with questions. In short order, he was explaining art design in between bites. The others chatted about their jobs as well. Rick rarely had much to say. The life of a banker was pretty mundane. Carrie loved to talk about her dress shop and her new designs, but it was terribly dull to the two men. She tried to create some artistic link between Mark’s work and her own, but Mark did not care much for artistry in clothes. He liked practicality.

As they chatted, Rick scooped up forkful after forkful of the casserole. He was surprised to find that he liked it. The whiskey had dulled his taste slightly, but the more robust flavors managed to get through. Even so, something about the dish tasted strange. The texture was grainier than it should have been. Rick seemed to notice as well. Mark caught the unpleasant expression on the other man’s face a few times. Neither of them stopped eating it though. The girls lapped it up as well, ignoring the rest of their plates. Mark started to notice the two exchanging quick looks. “What are you two up to?” he asked finally.

Laura batted her eyes in faux innocence, “Whatever do you mean dear?”

Rick joined in, “No, Mark’s right. You two are acting strange, even considering the…you know, plans.”

Laura giggled. “I guess it’s time we started talking about the elephant in the room. Not really sure how much longer we have to talk about it actually.”

Carrie looked at her watch. “Thirty minutes from ingestion. So maybe ten-ish?”

“What the hell are you two on about?” Rick said, his voice no longer humorous.

“Now, don’t get mad,” Carrie said, soothingly. “We knew you guys would be super anxious about tonight.”

“Our research told us that it’s not the idea of sleeping with another woman and incurring your spouse’s jealousy that bothers you,” Laura explained while waving a wine glass. “You’re more worried about your wife thinking of you as inadequate if you let her sleep with someone else. Even if it’s a closer friend. And it’s not even a physical thing. Men worry just as much about emotional betrayal as physical. They even think of the two being more closely linked than women do.”

“Right,” Carrie continued. “You know some women don’t get that mad if their man is sleeping around so long as she is the one he comes to for love and affection. For men, it’s kind of the same, but since you link physical contact with affection so closely, you feel betrayed emotionally by the physical act. Women do too, but in a more round about way.”

Mark clenched his fist on the table. His heart raced, and waves of imbalance washed over him. “What the fuck are you talking about all this for?”

Laura put her hand on his forearm. Her touch sent sparks through his body. “We didn’t want this to become some cock measuring jealousy fest because Rick fucks me or you fuck Carrie. There’s no way you two would have kept being friends after this. So we decided to take a different approach.”

Carrie was somewhat shrinking under Rick’s angry gaze, but she didn’t give in. “If we’re the ones doing the fucking, then you won’t get jealous. What do you care if I fuck Mark? You only would get upset if he’s fucking me.”

“They’re the same god damn thing. Now what the hell did you put in the casserole. My head feels like it just did six rounds on a roller coaster.”

Laura answered, “Change-X.”

Both of the men’s eyes went as large around as dinner plates. They both blurted out a string of objections, but only Mark’s was heard. “Are you fucking insane?”

The two women rose from the table with furtive glances. They shrugged at their shocked husbands. “We’re going to the bedroom. I think you should both join us. At the very least you’re going to want looser clothing.”

The girls left. Mark and Rick turned to look at each other. “They didn’t,” Rick said softly. He took his fork and prodded at the casserole, finding nothing in his inspection. “They didn’t right?”

Mark could still feel where Laura had touched him. The spot on his arm burned and radiated heat. “They did. They dosed us with Change-X.”

“What do we do? How do we get it out of us? Shit, how do we get it out of them?” Rick’s voice quickened. Mark’s eyes raised as his friend’s normal low baritone cracked into a softer, more effeminate tenor.

“No getting it out of you. Just have to ride it out. I remember in college they would have those parties before it was restricted. I never went. Always thought it was too weird. Kind of don’t have a choice, man.”

Rick looked crushed. He held his hands up in front of him. “When does it happen?”

Mark stood up from the table. “I don’t know, but the girls are right. We’re not going to want to be clothed when it does.”

Chairs rattled against the floor as they made their way out of the dining room. Rick followed Mark down the hallway to the master bedroom. When they arrived, Laura was already in her underwear helping Carrie tug off her pants. Mark looked at his wife in frustration as she twirled in front of a wall mirror, inspecting her body for any changes. “Decided to join the party, boys?” Laura teased. Both men’s eyes went to Carrie’s round, white ass as the pants came away. Her thong covered little. Mark happily took in the sight until his wife tossed aside her bra. Rick gawked. He’d seen Laura in a bathing suit before and hadn’t expected to be so surprised by the size of her breasts. He liked Carrie’s small tits, but did sometimes wonder about burying his face in a chest like Laura’s. She inspected them idly, as if surprised to see them at all.

“You should have talked to us about this,” Mark squeaked. His voice cracked as he tried to clear his throat.

Laura came over to him, her face actually contrite. “Oh, I know, but neither of you would have wanted to try it. We know you’re going to love it, but getting you to try it would have been a nightmare. Just getting you both here tonight at all was nigh impossible.”

“Have you done this before? Either of you?” Rick asked. He tried to fixate on his anger and outrage, but the strange feelings spreading over his body grew more distracting by the second.

Laura shook her head, but Carrie answered, “Yes, I have. It was years ago.” She sauntered over to Mark and took him by the belt pulling him to the bed. “Don’t worry,” she whispered, “The Change-X version of me has a thick cock.”

Carrie’s hands moved over his body, unbuckling his belt and pulling down his jeans. Mark watched as his wife led Rick to the opposite side of the bed. Laura looked different. Her shoulders looked slightly broader and her breasts had shrunk. Rick had changed too. He looked thinner, and his hair hung down below his neck. Laura opened his shirt and pulled it off of him. Rick’s normally buff chest had softened into a flat board with small lumps of tissue behind his nipples. Mark realized his own body was changing as well. Carrie pulled off his clothes revealing a smooth, pale chest. His chest hair had fallen away leaving smoother skin than he’d had since puberty. Mark looked down at Carrie as she pulled his jeans away from his legs. He could feel her breath on him. The idea of his friend’s wife being so close to his cock definitely aroused him, but he didn’t see his cock straining forward against his boxers.

His attention turned to Laura. His wife pushed Mark onto the bed and pulled his legs up in the air to finish stripping him. The two men had worked out together several times and, by chance, seen one another naked in the locker room. Rick’s cock was nothing special, normal size and everything, but it wasn’t even that any more. As Laura pulled his legs up, Mark caught a glimpse of the shrinking nub of his friend’s dick nestled at the top of folding skin. A twinge of panic flooded into Mark’s system. He reached under the band of his boxers and grabbed for his familiar manhood, but found nothing. His palm flattened out as Carrie pulled away the last of his clothes. The butt of his hand rubbed against the remnant of his penis, a tiny bundle of nerves, while his fingers traced the outline of smooth pussy lips. Carrie smiled up at him, “You’re coming along quite nicely, Mark.” Her tongue slipped out of her mouth and lightly wedged itself into Mark’s new folds, causing his body to quake with pleasure.

The changes manifested more quickly around the room. Rick laid on his back massaging his chest where heavy orbs grew in rapidly. Laura stood between Rick’s legs frowning as she felt her own butt. Though it wasn’t becoming the flat ass of her husband, it lost a considerable amount of its volume, disappointing her. She liked men with big butts, after all. Carrie, meanwhile, focused on her own new growth. She pushed Mark down on the bed such that his head rested beside Rick’s while the two changing women stood on either side of the bed. Carrie looked down at her crotch with a sort of mad laughter. Mark followed her gaze. The thin bit of underwear she still wore was being awkwardly shoved aside as a thick cock pushed its way out from her. The thin bit of fabric wedged itself between her growing balls. As she pulled it down, Mark could only look at the thick rod and let his mouth water.

Rick was in a similar position. He felt a light pop between his legs and took his hands away from his soft, new tits to explore his new pussy. Whatever hesitancy he had about being tricked and changed into a woman vanished as he sunk a finger into his hot, wet sex. A new craving came over him, something he had never experienced before. As a man, he had wanted to touch, to feel, to claim, but now his urges were slightly different. He wanted to be touched, he wanted to be filled up, he wanted Laura to be close to him. And she was rising to the task.

Laura stroked her cock in her hand, amazed by the feeling. Each stroke urged forth a little more excitement, made manifest in the ooze of precum issuing forth from the head. She loved the feeling of power it gave her. Moving her other hand down, she cupped her new set of balls. The weird, squishy feeling pleased her. She was surprised to find that gently rubbing them felt nice. Her eye was caught by the changing person in front of her though. Rick watched her with hopeful eyes. His newly feminine hips spread wider to let her get close to him. She hunched over him to lower her head to his breasts. Taking one of the nipples into her mouth, she swirled her tongue around the nub and sucked, hard.

Mark’s change was almost complete. His flat butt rounded into a big, plush ass. Tits twice the size of his wife’s wobbled on his chest as he stroked his new pussy. He loved every second of it, but knew something was missing. Carrie loomed over him, looking at him greedily. She looked little like herself. Her hair was still back in a pony tail, but her jaw had thickened to match her broad shoulders. The glorious pair of tits she’d sported earlier had transformed into rock hard pecks that sat atop a pair of washboard abs. Carrie hadn’t lied, the Change-X version of her was a stud. Mark hoped the female version of him was sexy enough for her. “Tell me what you want, Marki?” Carrie taunted. “Tell me what to do to you. Tell me who I am and what you want me to do, exactly.”

Desperation set in. Something in Mark’s body was going utterly mad to be fulfilled. “You’re Carrie, my best friend’s hot wife. And I want you to fuck me with your big cock.”

He felt pressure between his legs as she moved into position. Behind him, his wife laid on top of his best friend sucking on his tits while rubbing his pussy. Mark struggled to make sense of it all. He remembered some report that said people on Change-X could suffer identity shock and lose themselves. The warm buzz prevailing throughout his body quieted as his worries returned. He felt the nudge again and realized what it was. The fat head of Carrie’s cock was pushing against his pussy lips. Before he could react, she pushed again. Mark groaned in grateful pleasure. Mark thought back to the feeling of sliding his own cock into his wife’s wet pussy. The unbelievable warmth of it wrapped around his shaft always drove him wild and so he understood what Carrie felt as she pushed further into him. If she could link with his feelings at the moment, she didn’t show it. Her masculine face contorted in concentration, likely not trying to cum immediately from the feeling of Mark’s pussy squeezing her shaft.

Rick’s mind was no better in comprehending the changes to his body. Laura pulled off of him suddenly. Newly powerful hands gripped Rick’s hips and flipped him over. He could feel his new ass shake as he landed on his hands and knees. From this position, he had a full view of his wife’s new cock slipping further and further into Mark’s pussy. It excited Rick even more, his own pussy drenched in arousal. Laura’s strong hands took greedy handfuls of his ass, massaging the big orbs and reveling in the feel of female flesh. Laura’s cock slid against his pussy, and he ached with need. Rick mimicked something he’d seen a thousand times in porn, lowering his shoulders to the bed and scooting his ass as high up as he could, giving Laura a full view of his engorged lips. Laura wasted no time. Taking her throbbing cock by the root, she put it against the slick entrance and pushed inside her friend.

The room filled with the sloppy sounds of sex. Both couples breathed heavily as they all rode waves of pleasure. Mark concentrated on the feeling of the cock thrusting inside of him. He could feel Carrie’s dick throbbing in rhythm with the thrusts. Mark wrapped his legs around her, pulling her into him with more force each time. Wet smacks came from behind them as Laura pounded into Rick from behind. Mark could look underneath them to see Laura’s balls swinging forward to smack against Rick’s clit. Carrie’s rhythm changed, and Mark knew what was coming. His own pleasure built to a simmering ember, ready to ignite. The idea of Carrie’s balls emptying inside excited him all the more. He concentrated and squeezed his pussy muscles, trying to milk the cock invading him. With little warning, Mark felt the first gush of cum inside of him. A dam broke, and his world became nothing but sparkling lights. His arms wrapped around Carrie’s neck, pulling her down to him while his legs pulled her cock all the way in. He wanted every spurt of Carrie’s cum to splash inside his pussy. With each spray, his orgasm reached a new peak as wave after wave of ecstasy rolled over him.

Behind them, Rick moaned and squeezed his tits as Laura slammed into him from behind. Laura’s fingers gripped Rick’s ass so hard that she left small divots in the soft flesh. With a huge gasp, her cock slid out of her friend’s husband. The long, wet member slapped against Rick’s ass, wedging itself between the large cheeks before Laura groaned and sprayed cum all over Rick’s back. Laura kept thrusting, rubbing her cock between her friend’s ass cheeks and urging rope after rope to spill down his feminine back.

The two new males fell onto the bed, their cocks half erect and shining with lubrication. Rick dropped down onto his stomach, enjoying the feeling of Laura’s warm jizz on his back. Mark focused on the feeling of Carrie’s cum dripping from his pussy onto his thighs. “How long does this stuff last?” he asked, surprised to hear a soft female voice come from his lips.

Carrie answered between deep breaths, “About twelve hours.”

Mark crawled onto the bed and positioned himself beside Rick. “Guess us girls will have to give you a show to get you going again then.” With that, he pulled Rick into a deep kiss. In moments, they were both upright, rubbing themselves together while Laura and Carrie watched.

Laura whispered, “How much of this stuff do you have?”

Carrie grinned, “More than enough.”
