Adam silently fumed at Simone's deception. He'd thought they could just have a nice hike. Instead she'd led him out here to seduce him again.


It wouldn't be the first time that Simone had duped Adam like this. In fact, it was almost exactly a year ago that she'd done it last. It had been the middle of May, and she'd invited him to her aunt's house in the wealthy suburbs of Pennsylvania. It had been only a year since they'd both graduated, and Simone was living with her parents, while Adam rented a small apartment in the city, close to the school where he was working on getting his MBA through a 1-year program.


Fortunately, the art studio where Simone worked was only a few blocks away from his school, which allowed them to have lunch together almost every day. Living apart provided natural boundaries for them, and allowed Adam to push for longer periods between having sex, to limit Simone's growth. The last time they'd fucked had been 2 weeks ago, but before that, they'd waited 5 months - a new record for them.


Both had agreed to wait until October to do it again. 6 months was a long wait, but Adam was focused on finishing his MBA, and Simone was still new at her job. She'd grumbled, but had agreed that it would be for the best. Which was why, 2 weeks later, sex was the furthest thing from Adam's mind when she'd invited him to her aunt's house. It was a pool party, she'd said - her whole family would be there, having a cookout. Adam had met Simone's parents and sister before, but not her extended family yet. He was nervous as he pulled into the long driveway that led to the house where Simone's Aunt Wanda lived.


The driveway was long, and the sun cast dappled shadows through the towering trees that stood on either side. The landscaping was pristine, and as Adam approached the house itself, he realized that in truth, it was a mansion. He knew Simone's family had money, same as his family did. But the brownstone manor that rose above him was old, and belonged to old money. Apparently her Aunt was quite wealthy indeed. Despite its age however, the facade was well-kempt, and modern lampposts lined the freshly paved driveway, leading to a 3-car garage.


But as Adam got closer to the house, he frowned. There was only one other car in the driveway - Simone's red hatchback. He glanced at the clock. It was a little past 11am. Where is everyone? he wondered. Parking next to Simone's car, he grabbed the bottle of wine he'd brought, as well as his swim trunks and towel. He walked up the granite steps, listening for the sounds of people, but all he heard were birds chirping in the branches above the walkway. The steps wound a long path up the hill from the driveway, toward the massive front door. Hoping he didn't somehow get the wrong house, Adam rang the doorbell, and stepped back.


After a few seconds, the door opened, and Simone greeted him excitedly. "Adam! You made it!" she exclaimed, swinging the door wide to invite him in. She was wearing a gray t-shirt and white shorts.


Stepping over the threshold, Adam looked around, impressed with the elegance of the foyer, with its marble floors and crystal chandelier dangling from the high arched ceiling. What he didn't see though, were any other people. "Where is everyone?" he asked, turning back and forth to glance down the hallways. His voice echoed around the large entrance, but he didn't hear any sounds of people in the other rooms. "I didn't see any other cars in the driveway."


Simone had maneuvered around Adam to close the door behind him, and as she turned around, she smiled up at him. "Well, um," she said, biting her bottom lip. "It turns out nobody else could make it. So it's just us."


Adam's eyes widened, and he blinked down at her. "What, uh..." he said, his eyes darting around the foyer again, as he tried to process what she was saying. "What about your aunt?" he asked, befuddled. "Is her car in the garage?"


Simone glanced off to the side mischievously. "Well... she's not here, either." she said, then looked back up at him. "She's on a cruise, actually, in the Caribbean. I'm house-sitting for her this week." Her smile widened as she rocked back and forth on her heels, and the pieces finally clicked into place for Adam.


"...There was no party today, was there?" he asked, raising an eyebrow and smirking. Simone shrugged her shoulder and looked off to the side again, feigning ignorance. "...Baaa-aabe," he said disappointedly, leaning his head back as he drew out the complaint. "Are you telling me I drove all the way out here for nothing? I thought I was gonna meet your family today. I even brought wine," he said, holding up the bottle.


Simone reached up and slowly took the bottle from him. "Oh, no," she said softly, smiling as she gently plucked it out of his hands. "Whatever will we do all day, with this big house all to ourselves?" Her eyes twinkled with delight.


Adam slouched his shoulders and let his head fall limp against his chest, letting out an exasperated sigh. "...Honey, I don't think this is a good idea." he said, looking back up at her tiredly. Simone frowned at his reaction, as he reached out and caressed her shoulder. "We made a schedule, remember? We can't have you getting too big, too fast... not before we have the money to find a place with some breathing room."


Simone looked up at him, her frown turning into a pout as he spoke. She sighed and flopped her head back, snorting in annoyance. "Rrrrgghhh. Fine," she said, rolling her eyes to complete the display of her disappointment. She held up the bottle in her hand and looked at it. "Well, at least have some lunch, before you head back," she said, raising her eyebrow at him. "There's plenty to eat in the fridge." She turned and stalked off down the hallway, her flip-flops slapping with each step.


Adam glanced back at the door. I should just leave right now, he thought. But it had been a long drive, and he was hungry. I'll just have a quick bite to eat, and head out right after, he decided, following her down the hallway.


The house was even more impressive on the inside than it was from the outside. The hall leading from the foyer passed by a large elegant dining room, a coat closet bigger than Adam's kitchen, and a staircase that led to the next story, with a curved banister of polished mahogany. Expensive ornaments and pieces of art tastefully decorated the walls. Simone pointed to a painting that they passed, which she had helped her Aunt Wanda pick out. Adam paused to admire it, complimenting his girlfriend on its tasteful subtlety, and how it fit the color scheme of the walls.


Eventually they reached the kitchen, which was massive, and would make a professional chef jealous with its counterspace and range of appliances. While Simone put the bottle of wine inside the wine cooler, he marveled at the kitchen setup, walking around the island in the middle of the room, running his hand over the polished granite countertop.


"Wow," Adam said. "Your aunt has a really nice place." There were even two sinks in the kitchen - one set into the island, and a larger one off to the side. He'd always enjoyed cooking, and this was his dream setup.


"Yeah, I know" Simone said casually, as she opened the fridge and began grabbing things out to place on the counter behind her. Ingredients for sandwiches - bread, cheese, meat, lettuce, pickles - were taken out, and Simone began assembling them onto two plates, while Adam wandered around the room. He poked his head into the pantry, and was amazed at how full it was.


"Does your aunt live alone?" he asked.


"Yeah," Simone said, as she slathered some mayo on a piece of bread. "Ever since my Uncle Kevin died, a couple years ago."


"I'm sorry to hear that," Adam said solemnly. Simone nodded and smiled sadly, while she kept making lunch.


"She's got a lot of food, here, though," he continued. "What does she do with it all?"


"Oh, she has kids, and grandkids. They come to visit her pretty often, and we come over sometimes," she said conversationally. "She also throws parties for her country club friends."


Adam nodded, familiar with country club parties. His parents loved to attend them, and had even hosted a few. He found them terribly boring. Circling back around the countertop island, Adam saw that the sandwiches were finished. Simone reached into the cupboard behind her and produced a bag of potato chips, shaking a handful out onto both plates, then pushed one over to Adam, as he thanked her.


"Wanna have lunch out on the patio?" Simone asked, grabbing a chip and munching it.


"Sure," Adam said, and followed after her as she led the way outside.


Like everything else in the house, the patio was large and beautifully built, with a small fountain burbling in the middle of it. They were on the second story, looking out over the enormous and well-manicured backyard. As Adam walked over to the railing, he saw that it looked directly down at the in-ground pool below them. He still had his bathing suit and towel under one arm, and he placed them down on a chair next to him while he sat down at the glass table and ate lunch with Simone.


The couple conversed casually while they ate, as they did when they had lunch in the city, during Simone's work day and between Adam's classes. Adam asked a few solemn questions about Simone's deceased Uncle, and then asked whether her Aunt Wanda was planning to find another husband.


Simone smiled at this, holding her hand on her mouth demurely while she finished chewing her bite of food. "I think right now, she's just having a good time," she said with an amused expression. "She's had a couple boyfriends since then, but, well..." she trailed off, looking to the side. "...let's just say, she broke up with her most recent one a few weeks ago, and booked this cruise right afterwards," she said, raising her eyebrows suggestively as she looked back at him.


"Ah," Adam said, smiling knowingly. "So she's planning on really having a good time on her cruise, then," he said with a chuckle. Simone smiled, and nodded as she took another bite of her sandwich. "Well, good for her," he said, as he took another bite of his own.


For a while, they ate in silence, enjoying the pleasant sunshine, and the sounds of birds chirping in the trees. "You know, it's too bad you weren't having a party, today," he found himself saying. "It's such a beautiful day; would have been nice to have a cookout, hang out at the pool..." He glanced at her, raising an eyebrow.


Simone sighed, and slowly licked some potato chip grease off her thumb as she looked around the patio. "...I'm sorry, babe," she said, her face sincere. "Next time we do have a cookout, I'll let you know, and you can meet the whole family."


Adam nodded as he finished chewing his last bite of sandwich, and pushed out his chair to stand up. "I'd like that," he said, as he took a stretch. It was going to be a long drive back. "Thanks for lunch, honey," he said, smiling at her appreciatively. He knew he needed to get going - the longer he stuck around, the harder it would be to leave.


Simone's face fell suddenly. Her sandwich was only half finished, but she stood up anyways. "You can still go for a swim, babe," she said, grabbing her plate. "C'mon." She shrugged her shoulders, and skirted around the table. "It's a nice day, and you brought your swim trunks." And she bustled past Adam before he answered, heading back inside.


It WOULD be nice to take a dip, he thought as he grabbed his own plate, then collected his bathing suit and towel. It was nearly noon, and the heat of the sun directly overhead was starting to bake the stone patio. The rational part of his brain flashed a warning, though, as he followed Simone inside. It's not worth it - just thank her for lunch and leave, he thought.


In the kitchen, Simone was covering her plate with plastic wrap, saving the rest of her sandwich for later. She put it in the fridge, while Adam put his empty plate in the dishwasher. "C'mon, you drove out all this way, honey," she said, as he turned from the counter. "Let's just hang out by the pool, for a bit."


Adam looked at her for a moment, considering. She stood with her arms crossed, hips cocked to the side, and shrugged casually, as if to say, "Your call". Her expression had none of the desperation that she would show towards the ends of long breaks between sex. It had only been two weeks. Her eyes seemed normal; there was no sign of hunger in her gaze.


Still, though, she looked cute, standing there in the kitchen. Dangerously cute. Get out while you still can! his brain warned. But he didn't want to be rude, leaving so quickly. And he loved her. Did they really have to avoid each other so strictly? He sighed. "Yeah, alright," he said with a smile. "Just a quick dip, then I'll hit the road."


Simone immediately did a little hop, and clapped her hands in excitement. "Great!" she said in a high voice, and bounced towards the door that led to the stairs. "You're gonna love the pool, babe," she said as they descended. "I would've felt bad if you didn't get a chance to use it, after such a long drive. And it's the perfect weather for it, today."


She opened the door onto the pool deck, which consisted of a large rectangle of blue and white tiles that outlined the pool. The pool was decently-sized, although quite shallow. Adam saw that the deepest part was only 5.5 feet deep, and there was no diving board. Still, the pristine water sparkled brightly in the sun, beckoning him to take a plunge. There were lounge chairs spread out around the deck, and a grill set into a countertop far off to the side.


"Oh, hang on" Adam said, realizing there wasn't a place where he could change into his swim trunks. "Where's your bathroom?" Simone directed him through the sliding glass door that led from the pool deck into the basement. The basement was an entertainment room, complete with a pool table, a dart board, and a bar complete with beer taps. By the side of the bar was a bathroom, which Adam used, and then he changed his clothes.


As he padded barefoot back out onto the pool deck, he saw Simone was in her bathing suit, as well - a bikini, which was patterned with diagonal yellow and blue stripes that matched on top and bottom. She must have been wearing the suit under her clothes. Damn, he thought, feeling a little thrill as soon as he saw her. It was rare that he saw her in a swim suit. He'd forgotten how great she looked in one. Her back was turned to him, and he couldn't help but admire her ass in the bikini bottom.


She had sunglasses on, and was laying out a towel on one of the beach chairs, getting ready to do some sunbathing. He looked away from her, before she caught him staring. Easy, cowboy he thought to himself. You aren't here for that. He planned to just swim around for 20 minutes or so, that way he could say that he accepted Simone's hospitality. Then he wouldn't feel so bad for leaving her alone to watch the house. Stripping his shirt off, he put his clothes and shoes on the chair next to Simone, then took a running jump into the pool.


The water was colder than he expected, and the shock of it made Adam gasp when he got to the surface. "You okay?" asked Simone, smiling from her chair.


"Yeah, babe," he laughed, as he spit out water. "Water's a little cold, is all."


"Yeah, I guess it's still spring," she said. "It was pretty chilly outside this morning."


Adam shivered, but he knew he'd get used to the temperature. He walked around the pool a bit, working his legs in the water, as he acclimated to it. After a few minutes, he didn't feel cold anymore. He also didn't really know what else to do in the pool, now that he was in it. Usually, a pool party would have multiple people in the pool, and maybe some people on the patio to talk to, as well. He glanced over at Simone, who had reclined into a sunbathing position. She looked comfortable, and he didn't want to distract her. So, lacking anything else to do, he began to swim laps.


The pool was well-dimensioned for swimming laps - unlike some private swimming pools, the steps leading into the water were in the corner. This gave Adam a straight lane where he could traverse the pool with smooth, repetitive motions. He was a strong swimmer, but without goggles, he found himself needing to swim somewhat awkwardly, to keep his eyes above the water. As he got some exercise, he did some more thinking. What am I doing? he wondered. Why am I still here?. He knew that leaving as soon as possible was the best move. The problem was, he didn't want to leave.


Partly, he was lamenting the drive home. He'd been here less than an hour, and having to get back on the road for the long trip back to the apartment seemed like such a waste of a beautiful day. He also didn't want to be rude to Simone.


Despite her deception, it had been a nice gesture for her to invite him out today. They rarely got to spend time alone together, and never in such lavish surroundings. Both their parents were well-off, but with the young couple still being fresh out of college, it would be a few years before they could buy their own home. And he couldn't see them ever affording a property such as this one - not unless Adam got serious about earning some money. Was it really so bad for them to just spend some time here, enjoying the lovely amenities of her aunt's mansion?


Each time Adam swam past Simone's chair on the side of the pool, he kept glancing at her out of the corner of his eye. God, she's so pretty, he thought. She really did look incredible in a bikini. She was sitting up again, rubbing sunscreen on her arms. He couldn't tell where her eyes were watching, behind her sunglasses. But she wore a small smile on her face as she applied the cream, and slowly rubbed it on herself. He couldn't help but notice when she squirted a line across her upper chest, and raised her hands to massage it into her skin.


He tore his eyes away from her before he could see much of it, but the brief image he'd gotten was already locked into his mind. Trying to avoid any further glances towards her, he switched strokes on the next lap, turning his body around and starting the backstroke. He had to close his eyes against the bright sun overhead.


But unfortunately, his imagination was actively filling in the scene of Simone applying sunscreen, in his mind. He pictured her cupping her breasts and slowly rubbing the lotion onto them, her hands moving in circles as they trailed all over her chest. He imagined himself leaning over her instead, and him being the one to apply the cream. He imagined her breasts growing, as he did so.


As the images sprang into Adam's brain, he felt an erection coming on, his dick pulsing in his swim trunks as he swam. Oh, shit, he thought, feeling his tip rising above the surface of the water while he paddled backward. He'd meant to do a few laps of the backstroke, but instead he was forced to switch back to swimming face down, so Simone wouldn't see him getting aroused.


He transitioned to the breaststroke, which was the easiest stroke for keeping water out of his eyes. Unfortunately, the name of the stroke triggered his imagination even more. He imagined Simone's breasts growing inside her bikini, and felt his cock stiffen under the water. It quickly became uncomfortable, as it was now rubbing against the inner netting of his swim suit with every stroke. It didn't help that Simone was still slowly rubbing on sunscreen - now she'd reached her legs, and as Adam glanced over mid-stroke, her head rose towards him, and she smiled while she massaged the cream on her inner thigh.


Shit, he thought. He needed to get himself under control, and leave soon, before things got spicy. Closing his eyes and taking a breath, he dove down and swam underwater for a time, trying to expel the images of Simone from his brain. Dammit, I thought I could avoid getting horny, today he thought angrily.


Before leaving this morning, he'd made sure to jerk off, to satiate his libido before seeing his girlfriend. While masturbating, he'd taken inspiration from their most recent sexual encounter a couple weeks back, remembering how big her boobs she'd gotten. Imagining them even bigger. Picturing how large they would be, come October. You could check on their size again, today. The thought rose up from his primitive brain, the part that only cared about pleasure. It gleefully visualized just how easy it would be to take that path, instead of heading home. There's nobody else here, and the backyard is hidden by trees, it cackled. Nobody would stop you, and she would love it.


Adam squeezed his eyes shut tighter underwater, and gave his head a violent shake, trying to clear the dirty thoughts out of his mind. But his cock remained hard, continually chafing inside his swim shorts every time his legs extended. Eventually he bumped the wall of the shallow end of the pool, completing his lap, and came up for air. He stood up in the hip-deep water, then crouched back down as he felt his dick pressing against the netting of his shorts again. Man, that's super uncomfortable, he thought.


He kept his back to Simone as he leaned against the side of the pool, mentally berating himself for being so horny. Willing his boner to go down. He tried to focus on objects around the pool, checking out the grill, trying to determine what brand it was. He peered in through the sliding glass door leading to the entertainment room, seeing if he could read some of the kitschy signs that were displayed on the wall behind the bar. Desperately, he tried to get his mind off the image of Simone laying in her chair.


Just as he started to feel some of the blood flow leave the area, Simone suddenly spoke up behind him. "Hey, babe?" she asked lazily, her voice sounding a bit muffled. "Before you leave, can you get my back?" Adam looked over his shoulder at her. She'd finished putting sunscreen on her front, and was laying face down, now, resting her head on her arms. Looking at him. She'd taken off her sunglasses when she'd changed position, and as soon as his eyes met hers, Adam felt his dick pulse. Immediately, his rod got hard again. SHIT! he thought.


Trying to appear casual, Adam turned around and slowly started moving in her direction. "Sure, babe," he said nonchalantly. "I was just about to head out, anyways." But as he paddled towards her, his mind was racing to figure out how to get out of the pool without her noticing his hardness. Her chair was only a few steps from the pool's edge. She watched him calmly as he approached, and Adam swam in an arc, so that he'd end up directly behind her when he was getting out. He tried to suppress his boner in the few seconds it took him to reach her side, but it was no use. He had to just chance it, before she got suspicious why he was taking so long.

With a heave, he sprang out of the water, keeping one leg tucked in, and got up on the edge in a kneeling position, carefully diverting his erection down the leg of his shorts in one smooth motion. Simone's back was to him; as long as she didn't see him in profile, he thought he could avoid her noticing his hard-on. He stood up, but as he took a step forward, he intentionally stumbled, allowing him to stay crouched as he made his way towards her. "Woah!" said Adam, smiling as he came around to Simone's side. He kept his crouch as he reached his own chair, and, keeping his hips pointed away from her, spun around to sit down on the chair beside her.


"Easy there, clumsy," Simone said with a small smile. She was still looking at him calmly. He didn't think she'd noticed anything, despite his odd movements.


Adam chuckled, letting one arm hang casually over the bump in his swim shorts as he reached over and grabbed the towel he'd brought. Man this sucks, he thought, as the netting of the shorts pressed against his sensitive member again. He dragged the towel over and began to dry himself off, grateful for the temporary screen it provided. In his mind, he screamed at his erection to go down, knowing that he'd need to stand up in a few moments, to apply sunscreen to Simone's back. But despite the discomfort of the swimsuit, despite the inconvenience of getting one right before he needed to leave, the boner simply would not dissipate.


After Adam thoroughly scrubbed the towel on his hair, he realized he had nothing else to dry off. He would have to stand up. Letting the towel drape over his shoulder on his left side, the end dropping near where his erection was hiding, he caught Simone's eye again. In the bright sun, her iris reflected a brilliant emerald color. She was watching him silently. Adam's heart was thumping in his chest, now. She's so beautiful, he thought.


And then immediately afterwards, came the warning, Get out of here! Now! Leave! he thought. But he still had one thing to do, first. If only he could avoid giving himself away.


Licking his lips, Adam tried to stall for a little more time. "Sorry that I have to leave so soon, honey," he said, smiling sadly. "I just, um... we can't..." he trailed off, looking into the backyard. "You know how it is," he finished awkwardly, rubbing the back of his neck.


Simone's lips pursed in a pout. "I know, baby," she sighed. "Someday, we'll find a way to make this work for both of us."


She really was just going to let him go, Adam realized. If he could just apply her sunscreen without her noticing his boner, he could escape. He'd be able to keep his back to her the whole way inside, and once he reached the bathroom, he could calm himself down enough to leave.


Reaching over to the small table between their chairs, Adam grabbed the bottle of sunscreen. In a last-second decision, he knelt down next to Simone's chair, rather than standing. The better to hide his boner, leaning on one knee, with his hips turned away from her. He squirted sunscreen in a few spots on her back, and then turned and put a line down both legs. She's so close. She's so pretty, he thought, and swallowed.


He started rubbing the lotion onto her legs, marveling at how soft her skin felt. Her legs were perfectly smooth - she must have shaved them today. Adam's heart pounded as he slid his hands up her calves, towards her thighs. Stay focused, he thought, taking care to keep his erection pointing below the chair, along his knee. Almost there. Almost free. He felt sweat forming on his forehead, and the back of his neck, despite coming from the cold pool only a minute ago.


His hands worked their way up her thighs, massaging the cream into her skin. God, why did she have to wear a bikini? he whined in his head, as he approached her bum. Her cheeks, poking out from the yellow and blue striped garment, were so enticing, only inches from his face. A bead of sweat trickled down his neck, and he suddenly was finding it difficult to breathe normally. But he kept his touch professional when he reached her backside, avoiding the urge to squeeze her cheeks, or stick a lotion-covered finger in between her thighs. He was just doing her a favor before he left, that was all. Just a normal thing that couples did for each other.


Finally making it past her bikini line, Adam spread around the pool of sunscreen that he'd squirted on her lower back, feeling the ridges of her spine, and her lower ribcage. Then he scooted himself forward to get the rest of her. As he turned, again making sure he positioned his boner so it stayed below the chair, he saw Simone looking up at him. Her eye was wide, sparkling green between strands of her hair. He suddenly felt the irrational worry that she could hear his heartbeat, this close. It felt like his heart was going to pound out of his chest.

Just keep it together. You're almost there, thought Adam, as he reached over to the last pool of sunscreen that he'd placed on her shoulders. He spread it around her neck, and her upper back, working his way down towards the center of her back. As he rubbed her, he heard Simone exhale, as if she was out of breath, too. He struggled to control his breathing, but as he made it down past Simone's shoulders, he realized he was in trouble.


Her boobs were bigger. The bikini strap had grown tight across her back, and he could see flesh bulging out to the sides. His hands, slick with cream, slid around the strings of her bikini top, and as he did so, he saw the string getting tighter, digging into her skin. Simone was slowly rising upwards atop the cushion of her growing breasts. Touching her had been a bad idea.


Adam's hands ceased the slow circles he'd been making to rub the lotion into her skin. His eyes grew wide as he knelt next to his girlfriend, watching her breasts slowly inflate, flesh bulging out of the side of the bikini cup right in front of him. "Don't stop," Simone whispered breathily. "You missed a spot."


And suddenly, she twisted her torso around to face him. Her tits were already crammed for space in the yellow and blue striped bikini top. Adam knelt there, his hands hovering over her body. They were both openly breathing hard, now. Adam's eyes greedily took in the sight of her cleavage, then flicked to her face. The hunger had returned to her eyes, and they flashed electric green in the bright sunlight.


Simone trailed her hand up her belly, past her ribs, nestling her delicate fingers in her cleavage as she reached her breasts. "Right here," she breathed, arching her back while she pointed in the center of her chest. Her boobs were still swelling, mashing together in the tight top. "It needs a little more lotion, babe," she whispered breathily, her eyes flicking to the bottle on the table.


At this point, Adam was a spectator in his own body. He felt totally detached from himself, almost as if he was floating behind and above his own head, watching the events unfold. His hand reached out and grabbed the bottle of sunscreen, flicking open the cap in one smooth motion, and squirted out a massive dollop into his other hand. Then, he leaned forward, and glommed onto her tits with both hands, spreading the lotion around in her cleavage.


Simone gasped, and her breasts ballooned into Adam's hands, growing faster in response to his touch. She leaned back in the lounge chair as her boobs swelled, and Adam climbed up onto the chair to reach her chest better. His erection rubbed painfully against his swimsuit netting, but now he didn't care about it being seen - with a quick adjustment, he positioned his cock so that it rested in the waistband of his shorts, that way he could focus on more important matters. The lotion still needed to be spread out, and there was so much more skin to cover, now.


Kneeling in front of Simone as she reclined in the chair, Adam used both hands to rub the sunscreen all across her tits, inside her cleavage, around the bikini straps. Grabbing massive handfuls of flesh in the process, feeling it swell in his hands. Her breasts were packed tightly in the top, flesh pouring out the sides and the bottom of the yellow and blue striped top. After a few seconds of surging growth, the string snapped, and her boobs bounced outward onto her stomach. Adam's eyes widened. Now there was even more skin to cover. It wouldn't do for his girlfriend to get a sunburn. Not on her perfect growing tits. So he reached for the bottle of sunscreen again, and from above, squirted it all over her chest.


Simone laughed melodically as Adam coated her chest in a zigzag of lotion, squeezing the bottle to get as much out as possible, then releasing it and squeezing again. It spurted out another dollop, but it was nearly empty now, so he tossed it aside. Then he leaned down and began to massage Simone's breasts, spreading his hands in wide circles to coat them in the lotion.


"UNNHH!" she closed her eyes and moaned as her boobs swelled out bigger, accelerating even faster every time his hands brushed across her nipples. They were dominating her whole chest, and Adam had to move backwards on the chair as they crept down past her waist, now as big as yoga balls. As fast as he could rub their expanding surface area with lotion, more flesh appeared out of nowhere, and he was forced to raise his hands higher and higher to reach the tops of them.


"I think... I need to..." Simone mumbled in between heavy breaths, twisting her shoulders to the side as she braced against the armrests, trying to get up. Adam knew her intent immediately. She was growing too big for the lounge chair, and wanted to get to the ground. He stood up, and to make things easier for himself, peeled his wet swim trunks off, kicking them to the side.


Now, unencumbered by the troublesome netting around his groin, he helped to heave Simone's breasts to one side of the chair, and she fell on top of them, her back facing towards him. Her massive breasts pushed both chairs out of the way as they tumbled onto the tile of the pool deck.

The chairs made a grinding sound as they were shoved aside, and as her boobs continued to swell, they were slowly pushed further and further away. The small table between them was pushed forward, until it tilted forward and fell onto the smooth rocks that surrounded the edge of the pool area. Beyond the bed of stones was the lawn. Plenty of space for Simone to grow onto.


Adam swallowed as he saw Simone's ass in front of him now, looking juicy in her bikini bottom. His cock stood out straight as a rod as he stood behind her. It ached for her, but she wasn't ready, yet. The angle wasn't right. She was slowly rising higher on top of her breasts as they swelled bigger, but he was feeling impatient, now. Stepping over to her, he knelt down on one knee beside her, resting his elbow on her breast.


Simone looked up at him, her eyes sparkling excitedly, a giddy smile on her face. "I'm getting so big, honey," she said, her arms stretched out across the tops of her boobs. They swelled larger and larger; it was everything both of them wanted, in that moment. But it wasn't enough.


Adam just smiled a wolfish grin at her. He took a breath, and leaned in towards her. Then, in her ear, he whispered, "Grow for me, babe."


Her eyes widened. Then her smile turned into a shocked expression as she looked at her boobs, and suddenly they surged outward, growing faster than he'd ever seen them grow.


"UUUUUHHHHHHH!" she yelled, and Adam saw her whole body twitch a few times, as it rose higher off the ground. He thought she might have cum, just now. She looked back up at him, her eyes still wide, a manic smile on her face as she grew. "UHHH! I'm growing, Adam!" she said with a laugh. She was no longer kneeling, now leaning against breasts that were equal height with her. "I'm-UHHHH! Growing so big!" Her boobs spread out along the pool deck, shoving the chairs further apart as they dominated more and more of the space.


Adam stood up as he watched the spectacle unfold, slowly moving around to her backside. She was able to stand almost totally upright now, as her boobs grew taller than she was. NOW, she was ready to take him. He stepped forward, placing his hands on her hips, and gripped her smooth bottom for a moment. Then he gently peeled the striped bikini shorts down, and Simone arched her back upward slightly. Preparing himself to not cum immediately, he entered her.


"HAAAAHH!!" she shouted, and another surge of growth came out of her. Adam's feet slid across the smooth tiles of the pool deck, but he managed to keep thrusting.


Bigger and bigger Simone grew, surging outwards with each thrust from Adam. He thrust into her again, and again.


"HUNNHHHH!" bigger.


"HUNNHHHH!" bigger.


"HUNNHHHH!" and bigger still.


Until once more, he felt her reaching her limit. Her reverse thrusting slowed, and her expansion dwindled. Adam suddenly felt the ground under his heels change, and he realized he'd reached the rough cement that made the perimeter of the pool, which gave better traction near the edge. Mid-thrust, he glanced back, and he realized they were nearing the water.


Just then, he felt Simone spasm slightly, and take a breath. Then: "AAAAAAAAAAHHHHHHHHH!!!!!" she unleashed her final wave of growth. Once more, Adam came at the same time she did, feeling himself sliding back, back, back, until his heels passed over the lip of the pool's edge.


With his last bit of leverage, he gave her one more good thrust, and then he was airborne, gripping tightly onto Simone's shoulders as he continued to release inside her. He could only hold her for a few seconds though, before his sweaty hand slipped on her slick skin, covered in sunscreen. Dick still pumping as he fell backwards, Adam plunged into the water.

Hours later, Adam drove home. He spent the whole time cursing himself for his weakness, his inability to resist Simone. He was nothing better than an animal. We can't keep this up, he thought, furious with himself. Something had to change.
