Johnny has been wary of Sissy and the twins. When he was a she, and they had futa cocks, they weren't exactly easy on him, and for that matter, he as she, loved it. After he returned to normal, his pride took a major hit and he was annoyed with them. There were lines he, in his right mind, would not cross with his own sisters, but Sissy was another matter. Whenever they had the opportunity, Johnny was rough with his girlfriend, doing to her what she did to him. He found she liked it, and perhaps finds it humorous annoyed he was. One such opportunity for Johnny to take his aggression out on Sissy was the night before they had a week-long vacation from school, and Johnny's parents were going on their own vacation to celebrate their anniversary. The two lovers made a mess in Sissy's room, and Johnny stood up from the bed, satisfied in more ways than one, leaving Sissy on the bed, exhausted and covered in his cum. He made his way to her bathroom to wash himself, but stopped when Sissy made a clever comment.

"So, a week off, huh? I think we should spend it at your place. You take some of those Hottie Body Flakes, a take some Futa Fusion pills, and we have some fun with your sisters." The punk girl suggested, lying on her stomach and looking at Johnny. She made sure to flash her cleavage at him. It always bothered Johnny that Sissy was in no way weirded out by the scene of actual incest she walked into, or that he was having sex with other girls at all. He asked her about it before, worried that she'd break up with him. She would be right to do so of course. She explained that, while she wasn't okay with an open relationship, it was a science experiment with a controlled environment with his sisters. She also thought it was super hot, something that bothered him.

"Yeah, not happening. Not turning into a girl again, and not getting gangbanged by my girlfriend and my psycho sisters again. Nope." He flatly refused. Sissy giggled. "Like you didn't enjoy it. I did. You had some really good moves." She praised him. Johnny grit his teeth. "We were being manipulated! The girls said it themselves. No way would we actually enjoy any of that." He tried to explain it to his girlfriend. Sissy contemplated it. "Sure, but it's not like we were being mind-controlled. Heck, you were better at blowjobs than I was at that point. I learned moves from you. You weren't being forced to do any of that." She reasoned. "Man, the way you used your tongue..." She recalled with a amorous grin. Johnny loudly sighed and went into Sissy's bathroom. "No more girl Johnny! And no more futa Sissy either." He was adamant about that. Sissy merely giggled and began planning for a fun week-long vacation.

Johnny, Susan, and Mary waved to their parents as they pulled out of the driveway and headed to the airport. Johnny swore up and down that the house would be intact when they returned in a week. Their parents had left early to catch a flight, so the weary siblings lumbered into the kitchen to eat breakfast. "We built a new invention last night, the Fashion Blaster. It can create any sort of outfit you can imagine with just the pull of a trigger." Mary announced. "Uh huh." Johnny was still out of it, eating his eggs and bacon. He had a late night too, but he was less productive than his genius sisters. Sensing they wanted more from him, he added to his reply. "Sounds good. You'll put the fashion industry on notice." The twins giggled in response. "Yeah, we're careful about that. This will just be for us." Susan informed him, placing the large gun on the table. "It'll save us a ton of money on new clothes." Mary added. Johnny shrugged, too tired to care. After eating another bite of eggs, he grabbed the salt shaker to season his breakfast.

After seasoning his breakfast as he preferred, Johnny took a big bite of his eggs. In between chews, his body transformed into his buxom female form. She swallowed the food and looked down, immediately seeing the change in appearance. She immediately yelled. After finishing her house-shaking yell, anger coming over her and she glared at the twins. "You swapped out the salt for the Hottie Body Flakes?!" The twins looked to one another for a moment, before looking at the angry flame-haired girl. Susan spoke first. "Well, Sissy insisted on really enjoying your two-month anniversary, and far be it for us to stand in the way of true love." She excused their actions. Johnny grit her teeth, seething in anger. "No more girl Johnny, and no more futa girls!" She declared. The twins shared another glance. "Yeah, about that..." They said in unison. Johnny sighed, knowing exactly what they had planned. "No. None of that. Seriously, aren't you girls and Sissy straight? I thought Gil was gay, but you girls clearly have a thing for girl me." Johnny argued. The girls giggled. "Silly Johnny, we are straight, but we're also scientists." Susan clarified. "Right, and Sissy may have a new kink she wants to explore. As her boyfriend, you should support her." Mary added.

Johnny quickly scarfed down her breakfast, not really caring for the flakes on it since the timer won't extend past twenty-four hours anyway. Once finished, she rose from her chair and glared at the girls. "I'm going to my room until this wears off." She announced. Before she could move, Sissy burst through the back door and into the kitchen. She was excited to see Johnny transformed. "Yes! Now we can have fun." She cheered. "No we can't!" Johnny shouted. Susan aimed the Fashion Blaster at Johnny and pulled the trigger. In a flash of light, her normal clothes were replaced by a black skimpy bikini top with yellow hazard signs on each cup and a pair or small green hot pants. Johnny looked at his new attire and yelled again. "These don't cover anything! Why would you make these?" She demanded. The bikini top showed off more of her chest than necessary, exposing the sides of her breasts, and the hot pants were small and thin enough to see the outline of her flower and bare most of her cheeks. "Because, it's Swimsuit Day and we have plans." Susan replied, shooting herself and forming a blue one-piece swimsuit with the back cut out, and most of the front, completely showing off the bottom of her breasts, ending just below her stomach, with a french cut between her legs just barely covering her crotch. She takes aim and fires on Mary, forming a pink two-piece crop top bikini that had a window to show off her cleavage. The bottom of her breasts were also clearly seen. The shorts hugged her hips and ass, and showed off some of her pelvis. Finally, Sissy was blasted, giving her a black one-piece with vertical laces on the front, showing off the inner sides of her chest, and a short transparent flannel-colored skirt that only reached the middle of her thighs. The sides of the swimsuit had an usual style to them, showing off her hips and waist with a thin v cut that just covered her crotch, and definitely just exposed most of her ass.

The girls ushered Johnny into the living room and showed her the news. Hank Anchorman was on scene in front of a coffee shop, wearing a colorful Hawaiian shirt. "Hank Anchorman here! The Mayor formally announced Swimsuit Day! This may be a bid to help his lowering approval ratings, and it worked! Feel free to dress up in anything you'd wear to any beach!" The newscaster happily announced. Johnny's jaw hung open. "Say wha?" She was baffled. Sissy began to consider things. "Say, why don't we call you Joni while you're a girl? Calling you Johnny when you look like this is weird." The punk girl suggested. Johnny was about to argue, but something occurred to her. "Why does that name sound familiar? Never mind. The answer is no! No more girl Johnny, or Joni. Or whatever!" She refused. Sissy made a play to get Johnny to cooperate. She pretended to cry and give Johnny a sad face. "But I wanted to spend the day hanging out with some cool girls. Is that too much to ask? Did I do something bad?" She lamented. Johnny winced. She knew it was fake, but couldn't handle it. "Fine. Joni it is. No sex though!" She agreed, setting ground rules. Sissy quickly cheered up. "Does it look like we can hide anything in these?" She joked, clearly indicating that their clothes were too tight, or too little, to hide anything. The twins giggled and used the Fashion Blaster to create stylish sandals for them to wear outside.

Joni, Sissy, Susan, and Mary strolled along the sidewalk, heading downtown. Susan had a purse hanging off her shoulder, no doubt carrying the Fashion Blaster. "Are you girls sure you're comfortable in those? We're not even really covered up." Joni questioned them. Susan grinned. "Please Joni, everyone is dressed like this. We're fitting in." She explained, waving her concerns away. Sissy giggled. "Do you like my swimsuit, Joni? It's okay for you to look." The punk girl told her lover, striking a seductive pose by extending her leg and stretching her arms above her head. Joni gave her a wry look and grabbed her ass, sinking her fingers into the soft skin. "Yeah, I like it. I'd like it better if I had the equipment I need to enjoy it." She remarked. Sissy giggled again. "I'll remember that when you have that 'equipment' again." She joked, pulling Joni's hand off her ass cheek. Joni grinned and walked in step with Sissy.

The four reached downtown quickly enough and made plans to see the new Speed McCool movie when they bumped into Mr. Black and Mr. White, dressed in similar Hawaiian shirts and swim trunks. "Johnny, why are you a girl?" Mr. Black inquired. Joni sighed. "Because my sisters don't have girl friends." She explained, exasperated. "Aww. That's sweet of you to go the distance for your sisters." Mr. White praised her. The twins giggled. "Yep. That's our Johnny. Er, Joni." Mary agreed. The two agents laughed and walked away. Joni gave the girls a cross look before heading to the movie theater.

The girls settled in the theater to watch their movie. After purchasing some drinks and snacks, they took their seats. The theater wasn't exactly packed, so they had their pick of seats. Joni sat with Sissy on her left, and Mary on her right, with Susan beside Mary. They decided to use a special spray bottle that instantly sanitized their seats and the surrounding floor. No telling what was on them. Joni hoped an action-packed two hours of Speed McCool would brighten her day. When the movie finally began, Joni happily ate some popcorn and watched the high-speed chases and explosions. She felt a hand on her thigh, and looked to find its owner. Sissy casually placed it there. Shrugging, the flame-haired girl went back to watching her movie. Sissy looked at Joni from the corner of her eye and smirked. Mary did the same and watched Sissy. The girls had their own plans for the movie. A loud, action-packed movie can drown out most any sound, after all.

Sissy moved her hand up, and began to stroke Joni's inner thigh. The flame-haired girl stifled a yelp and glared at Sissy. Her girlfriend was merely watching the movie and sipping from her cup. The punk girl's hand moved again, gently running the tip of her finger along Joni's covered flower. Joni nearly jumped, but stopped herself. She grabbed Sissy's hand, but Sissy countered and took Joni's hand, placing it on her own barely-covered flower, and gave Joni a sly grin. Joni was surprised, and let out a slight yelp when Sissy moved her hand back and pulled down the zipper on Joni's hot pants, exposing her flower. Sissy began to rub her below, having access to everything there, due to the zipper extending from the button in front to the belt line in the very back, a feature Joni did not notice before. Sissy leaned closer to Joni and spread her legs. "Touch me, Test." She whispered in a sultry tone as she grazed Joni's clit. The new girl stifled a moan, and knew her switch was flipped. She pulled the small amount of cloth aside and rubbed Sissy's flower.

The two softly moaned as they masturbated one another. Joni could feel herself getting more aroused by the moment. Her heart raced in her chest. She never had any intention of doing anything sexual in public. She might share a kiss with Sissy outside, but everyone did that. No, sex in a public movie theater was not on the list of things she intended to do. However, as a girl, when her switched was flipped, but was up for anything with Sissy and the twins. Out of the corner of her eye, she saw Mary and Susan watching the movie, oblivious to what was happening. Joni spread her legs more, desperate for Sissy to continue to please her. She heard Sissy's labored breath beside her, and felt her girlfriend getting hotter. Juices began to flow from her, which only made Joni more aroused. She began to rub the punk girl's erect clit between her fingers, which made her audibly moan. However, Speed McCool's movies were known for being loud, so no one but Joni heard her. Or so she thought. She felt Mary place her hand on Joni's right breast. The kinder twin was giving her a wanton smile. Together, Sissy and Mary pulled Joni's bikini top down, exposing her chest to the darkened theater.

Mary leaned towards the flame-haired girl and gave her a brief kiss before moving down and licking her hardened nipple. Mary took Joni's hand and, like Sissy before her, placed it on her own waiting flower. Joni's head was already clouded by lust, so she eagerly pulled down the front of Mary's small and thin shorts to rub her warm flower. Mary let out a soft moan as she continued to lick and suck on Joni's breast. Sissy did the same to Joni's left breast, making the middle girl cry out in ecstasy. She felt Mary's fingers move between her thighs, joining Sissy's in teasing and playing with her wet and eager slit. Their fingers probed her inside and out, making her nectar flow. Joni kept her own fingers moving, pleasuring Sissy and Mary as much as she was by them, thrusting her fingers inside them, teasing their clits. Distracted as she was, she did not see Susan move. "This is the real reason why we wanted this area as clean as possible." The younger twin announced. She was on her knees between Joni's legs.

Sissy and Mary moved their hands away, allowing Susan to move forward and run her tongue along Joni's wet slit. Joni tried in vain to stifle a moan as Susan pushed her tongue inside the flame-haired girl. Joni continued to move his fingers inside Mary and Sissy, thrusting her digits in and out of them while her thumbs rubbed their clits. They moaned in pleasure as they licked and sucked each of Joni's breasts. The sounds she made were music to them. As much as Sissy loved Johnny, she had a special affection for his girl form. Susan noted how close Joni, Mary, and Sissy were, and decided to put in more effort. Despite not receiving any attention herself, she was aroused, and might just have her own release. She pulled her tongue out of Joni's eager flower and replaced it with two of her fingers. She began to quickly thrust her digits in and out of the girl while she licked and sucked on her clit. With her free hand, she began to play with herself, completely engrossed in pleasure enough to satisfy herself for now.

Susan and Mary timed things out well. Just as the four girls cried out in ecstasy and relief, a large explosion erupted on the big screen to drown them out, maintaining their cover. After licking Joni clean below, Susan rose to her feet, trying to maintain her balance in the process, and returned to her seat to fix her clothing. She enjoyed the soft moans Joni made as she pulled her fingers out of the flame-haired girl. Joni collapsed back onto her seat, chest heaving with each labored breath. She had forgotten what it was like to climax as a girl. Mary and Sissy pulled her fingers out of themselves and licked them clean, tasting their own nectar, before taking turns making out with Joni, giving the middle girl a passionate kiss each, before kissing one another in front of her. Joni was oddly aroused by the display, something else she would have to consider once her mind was clearer.

The girls fixed their clothing to cover themselves, though given how little clothing they wore, it seemed a moot point to Joni. She grumbled as they left the theater together. She couldn't really watch the movie since the girls kept playing with her. "Oh come on Test, you liked it." Sissy teased her. Joni glared at her. "I was looking forward to this movie." She retorted. Susan raised an eyebrow. "So you prefer movies to sex. Typical guy." The younger twin quipped. Joni crossed her arms below her chest. "No, but I don't go to movie theaters to have sex, do I? No, I go to movie theaters to watch movies. Like normal people." She argued. The girls giggled. "Well, you still had fun. If you really want to watch it, we'll set it up in the lab for you later." Mary offered. Joni shrugged. "Whatever. What do you want to do now?" She questioned. "To the beach!" Susan declared.

The beach was as packed as they expected. People were enjoying their fun in the sun, whether they were surfing or sunbathing. They caught sight of Gil surfing along a wave. The twins were marveling at the sight while Joni and Sissy picked out a spot that provided plenty of room for them. People were packing up, and they jumped in as quickly as they could. Gil walked past the twins ogling him and proceeded to check out Joni as she bent down to fix the towels. Mary's bag was larger on the inside, and packed with beach supplies. Joni felt an odd stare and stood up. She was quickly weirded out, and quickly pulled away by Sissy, who gave her a kiss to show Gil that Joni was taken. Dejected, Susan and Mary joined them by their towels. "I can't believe he was checking you out." Mary commented. Joni shuddered. "No kidding." She noticed how down they were and felt a pang of sympathy. "Hey, he's about as shallow as that kid's kiddie pool, and about as useful as a kiddie pool at a beach. Am I right?" She joked. The red-haired twins giggled, appreciative of her attempt to cheer them up.

Joni settled on a beach towel, sitting down and leaning back with her arms behind her to prop her up. She sighed in content, closing her eyes and enjoying the sun's rays. Susan and Mary pulled out a disc-shaped device and activated it. It created a transparent field around their spot, projecting a barrier to ward people away and a hologram that would deter any curious people from seeing or hearing anything amiss. The girls then moved on Joni, each taking a special pill that would let them really enjoy the beach.

Through her closed eyes, Joni noticed that something blocked the sun. She opened her eyes and was met with three clearly aroused girls, newly-formed cocks standing erect and aimed at her close to her face. She blinked, processing the sight, before getting annoyed. "No way! We're in public now! Everyone can see!" She argued. Sissy pushed her shaft closer, right beneath Joni's nose, filling her with the scent of her girlfriend's eager shaft. Joni felt light-headed for a moment, her pulse quickened, and she felt aroused. Shaking those feelings, she rose to her feet and looked around. Susan giggled. "Let me introduce you to the Super Safe Space. We can do anything here and no one will notice." She explained, pointing to the disc-shaped device. Sissy took the opportunity to go behind Joni and reach between her legs to unzip her shorts, pulling the zipper from the front to the back. She parted the jeans and slipped her erect shaft between Joni's legs. She then pulled the girl's bikini top down, exposing her chest to the twins. "Let's have some fun, Test. Sex on the beach is a new fantasy of mine." Sissy pleased, licking her girlfriend's ear lobe. Joni tried to resist, but the hot and hard cock rubbing her flower, and Sissy teasing his ear, flipped her switch.

Mary pulled her top up and showed her chest off. Susan unzipped the top part of her intricate suit to bear her own chest. Behind Joni, Sissy did the same, unlacing her top to get more comfortable. Sissy began to massage Joni's chest, gaining soft moans from the girl. "So, how do we do round 1?" Sissy asked the twins. Susan had ideas. "Well, I want to finish what I started earlier." She suggested. Mary nodded. "I'll take her from behind." The twins decided together. Sissy agreed. "I want these to myself then." The punk girl stated, teasing her girlfriend's nipples. Joni was too far gone to argue, wet and eager for the girls to begin.

The twins sat opposite one another with their legs laced one on top of the other. They leaned back with one arm behind them to prop them up. They made sure their futa cocks were slick enough to easily slide into the flame-haired girl. Joni settled between them, and the girls lined their hot and throbbing shafts with her holes. Aroused more than before, and still just as conscious of their surroundings, Joni pierced herself on their futa cocks, her flower and ass stretching to pull them in. With a loud moan from them, she hilted herself and readied for them to move on their own. Sissy stepped over Mary and aimed her hard shaft at Joni's mouth. Joni moved on her own, wrapping her large breasts around Sissy's shaft and rubbed them together. The punk girl began to buck her hips, pushing her cock up and down, always making sure the head of her cock slipped between Joni's lips each time she moved up.

Joni felt the twins move, easily finding a rhythm as they pierced her from below. They alternated their moves with one another, knowing just how Joni enjoyed it and where to tease her to really drive her wild. Sissy began to tease Joni's nipples as she thrust between her girlfriend's breasts. Joni herself could only think about pleasure, indulging in the feeling of being filled below. She wanted to swallow more of Sissy's shaft, but loved the feeling of it moving between her breasts. A part of her knew that she would be angry later, but for now, she would move her lower half and her chest to meet the girls's movements. Sissy noticed Joni's eagerness and grinned. "When you're a guy again, I might just let you play with my chest like this too." She told the girl. Joni could only groan in response. Mary began to play with her clit from behind, sending shivers through her. Susan giggled and began to gently rub Sissy's flower. "After all this, you could pretty much let him do what he wants." The younger genius twin suggested. Sissy let a soft moan escape her lips. "Yeah, you're right." She agreed.

Susan licked her finger clean of Sissy's nectar and decided to go for the source. She leaned forward and licked the punk girl's flower, making her moan louder. Having Joni and Susan both pleasure her at once was a new sensation, one she wanted to try more often. Joni took longer strides with Sissy's shaft, licking her from base to tip. It was still difficult to focus with Susan and Mary claiming her holes for their own, driving her absolutely wild. She still wanted Sissy to climax, and given how hot and throbbing her shaft was, and how much pre-cum was drooling out into her mouth, it would not take much longer. Susan began to thrust two fingers into Sissy's dripping flower, sending her over the edge. White ropes sprayed forth, painting Joni's chest and face, before the flame-haired girl could take the erupting shaft into her mouth to hungrily drink the remaining fluid. Susan and Mary began to rock their hips harder and faster, and Joni could feel them getting ready to fill her.

Pushing the limits of the Super Safe Space's sound buffer, the four girls cried out in utter bliss. Sissy, having already climaxed, carefully sat beside Susan and watched her girlfriend and the twins ejaculate. Joni could feel her insides filling with Susan and Mary's seed, and she indulged in her wanton desires, sighing in contentment as the softening shafts let loose in her. Susan and Mary leaned forward and held Joni, pressing their chests against her. Susan claimed her lips, tasting Sissy's fluids, while Mary kissed and licked the nape of her neck. Sissy giggled. "Hey, the day is still young. Let's get started on round two before you three decide to cuddle our day away." She suggested. Mary looked to her and nodded. "Round two of sex on the beach is a go." The older twin announced, feeling herself get hard again. Joni sighed, still in a dreamy state of lust as Susan's tongue explored her mouth.

By the time the girls were finished, the sun was beginning to set. They laid on their towels, Sissy resting her head on Joni's shoulder, and Mary and Susan using her Joni's stomach as a pillow. The girls had lost their futa cocks just a short while ago. They were spent for now, having stained Joni quite thoroughly, filling her insides as they could, while painting her face, neck, chest, and everywhere else with their fluids. She was essentially marked as theirs, and when she finally came to, she was annoyed. "I can't believe you gangbanged me on the beach." She spoke. Sissy giggled. "Sex. Sex on the beach. And it was amazing." She happily said, kissing Joni's cheek. Joni grumbled. Susan and Mary sat up and smiled to her. "It was amazing, and you were way into it." Susan recounted. Mary nodded. "Yep. Once your switch is flipped, you're as aroused as any of us. You practically drained us dry." Joni grumbled again, knowing it was true. She made plans to destroy the Hottie Body Flakes entirely, and delete their data on it. Along with the Futa Fusion pills, just to be on the safe side. She was rocked senseless most of the day and wanted to prevent that from happening again. If they got carried away, they might make plans to keep her as a girl, and with how much they normally pumped into her, she'd get pregnant for sure.

After some rest and making great use of cleaning wipes, the girls ate a quick meal and packed up their belongings. Joni still felt herself filled with their juices despite cleaning herself, which made her both sick and aroused, which in turn made her feel more sick. She felt self-conscious when Mary disabled the device. Though no one gave her a second look, Joni felt like all eyes were on her. Fortunately, the only eyes on her were Sissy, Mary, and Susan's eyes. They had plans of their own for when they got back to the Test home. Little did they know that Joni had her own short-term plans.

When they arrived home, Joni flopped onto the couch and sighed, disparaging herself for falling into their trap. Again. Sissy joined her on the couch and smiled sweetly. Joni scowled in response. "No more. We spent all day having sex. While that would be a good thing in most cases, I was the one getting screwed." She snapped. Susan and Mary joined them and each gave a sweet smile, before Susan leveled the fashion gun at Joni. She saw Mary placing a futa pill in her mouth, and acted quickly. She grabbed Sissy and used her as a shield while grabbing her futa pill and swallowing it. Joni moved Sissy off to the side and pulled down her zipper, watching as her own futa cock grew, as large and thick as the girls'. "Oh, this is gonna be good." Joni gave Sissy a sly grin. "Turn about is fair play, right?" She threatened. Sissy was wearing a Ladybird Scout uniform, complete with a pink neckerchief and green beret, but the green skirt was incredibly short, reaching just blow her pelvis, and the green button shirt was equally short, exposing the lower half of her chest. Sissy looked at herself, then to Joni and her new member. "Uh oh." She smiled weakly. "You wouldn't let your sisters have sex with your own girlfriend, would you?" She pleaded. Joni snickered. "You let my sisters have sex with me, as a girl, numerous times now." The flame-haired girl countered. Susan agreed. "At this point, I think we're in our own sort of relationship, so this is fair." A sentiment Mary agreed with. Joni gave them a side-ways glance. "Yeah, we'll talk about that later. For now, it's payback time."

Sissy quickly found herself in Joni's position. Her head was bobbing on her girlfriend's thick and throbbing shaft, noting that it tasted the same as when Joni was a guy. She was laying on the floor with Joni sitting right in front of her. Mary was sitting on the ground behind her, thrusting her hips and piercing her flower while Susan straddled her hips and thrust into her ass. "They're a great combo, you know? They know exactly how to double-team someone." Joni commented, having been on the receiving end of their attention quite a few times. Sissy groaned in pleasure. She understood how Joni could just lose herself. She wasn't going to complain though, the Test siblings were perfect for her. They were ravishing her like beasts, and she loved every second of it. The girls moved in perfect rhythm, pumping their hot and hard shafts into her, making her whine for more. Joni wasn't too sure about how much she was enjoying herself, and was worried she'd ask for more four-ways in the future. Her plan may have backfired a bit. Sissy hungrily took Joni's cock into her mouth and down her throat, letting her tongue twirl around and drag along the bottom. Much to Joni's dismay, she may have learned such techniques from Joni herself.

The three Test girls cried out in their living room, spilling white fluids deep into Sissy, filling her flower, her ass, and her mouth with the first shots. Sissy moaned and took everything as she climaxed hard, a bit harder than when it was just Johnny having sex with her. Susan giggled at her reaction. "Jeez Joni, I think she's a bigger slut than you." She slapped Sissy's ass, which just made Sissy moan again. Joni glared at her. "I'm not the one who keeps changing her brother into a girl just to have sex with her. If anything, you girls are the sluts." She challenged. Mary chuckled. "Let's just say that we have incredible chemistry with one another and leave it at that." Ever the compassionate one, she settled the issue and pulled herself out of Sissy's hot and wet slit, letting her fluids dribble out. Joni pulled herself out of Sissy's mouth and moved onto a nearby sofa chair, her futa cock ready for round two. Sissy pulled Susan out of her ass and stood up, eager to be filled by Joni again. Joni took her by her hips and spun her around, guiding her ass onto her shaft. Sissy slowly pierced herself, sighing as she felt Joni fill her up. Once she was hilted, Joni spread her legs and rested them on hers. Susan moved first, positioning herself between their legs, and lining herself up with Sissy's eager slit.

Joni and Susan bucked their hips, pushing their hot and thick shafts deep into Sissy. The punk girl moaned in wanton bliss. Mary moved to Sissy's side and teased the girl's chest, rubbing one breast while she licked and suckled on the other. Joni reached between Sissy's legs and began to rub her erect clit, which made the girl cry out. Somewhat resentful, and incredibly aroused, Joni thrust harder and faster into her girlfriend, which compelled Susan to keep proper pace. Joni wanted to really mess the girl up, something her sisters agreed with, and something Sissy was craving. With her ass and slit full, and her chest teased, she could do nothing but indulge in the unrestrained attention of the Test siblings. She arched her back and let out another cry as she climaxed. Joni and Susan did the same, ejaculating into Sissy once again.

After relaxing for a couple of moments, Sissy, Mary, and Susan went to their knees between Joni's legs and licked her shaft between their breasts. Finally, she felt in control. Lust was clear in their eyes as they pleasured her shaft, covering every inch with their tongues and chests. "Much better." She commented, letting out a sigh as Mary took her futa cock into her mouth. "Just remember Joni, we can only have this fun when you're a girl." Susan pointed out. Joni rolled her eyes. "Is this a ploy to get me to look like this on my own?" She wondered aloud. Sissy nodded. "Yup." Unashamed of the scheme, she admitted to it. Joni sighed and watched as Mary let Joni's shaft slip from her mouth so Sissy could take it. "Fine, as long as there's no more Joni gangbangs." The flame-haired girl relented. Mary giggled. "That's still going to happen, but you have the option to give as much as you take." The older twin clarified. Susan began to rub Joni's slit as the girls used their chests to pleasure her. They felt her throb, ready to climax again. Sissy let go of her shaft and worked with the twins to get her off, moving their breasts up and down, eagerly licking her member. They watch with glee as she climaxed, spraying them with her juices. They indulged themselves as they licked her clean, before licking themselves and giving Joni a show. They made exaggerated moves as they licked each other and shared intimate kisses, which only made Joni's softening member hard again.

Joni woke with the sound of a buzzing alarm. She spent all day yesterday having sex with her girlfriend and twin sisters, stopping only for brief breaks before getting back to it. She found herself wearing a laughably short and thin black tank top, which only covered half her chest, and her nipples were clearly poking through. Below, she woke a green thong that hugged her hips. Susan mercifully killed the alarm before snuggling next to Joni again. Joni looked around herself and recalled how the girls used an invention to make her bed larger, big enough to comfortably fit four people. Susan laid on Joni's right side while Sissy was on her left, and Mary was just behind Sissy. They were all completely nude. Joni looked between her legs and saw that her futa cock vanished again. Sighing, she rested her head on the pillow, remembering how the unusual relationship was ironed out. When Johnny was Johnny, he was in a committed relationship with Sissy. When Johnny was Joni, she was in a committed relationship with Sissy, Susan, and Mary. She was also instructed to wear the black bikini top and tight green jeans whenever she was in her Joni form. It was weird, but she was somehow convinced of it while she was cumming inside all three girls last night. With another sigh, she closed her eyes and went back to sleep.

Author's Notes: I'll be honest, this was born of just me wanting to dress girl Johnny in different clothing. I also saw the summer was here, and wanted a beach scene. For real this time, I don't see another chapter coming. This is a good ending though. I'm sure they'll be happy, even Johnny/Joni. Yeah I went with Joni this time around, the name of Johnny genderbend counterpart. It made it easier to write and read.

I hope you liked this chapter. I'll figure something out for the oft-promised and never delivered 50 follower story.
