The ad was vague, mentioning only "male modeling" and "great pay for open-minded candidates." Evan had filled out model consent forms online and posted a picture of himself wearing only a tiny Speedo. He was called back and invited to the studio the next day.

Evan had never imagined himself modeling in revealing underwear, but then again, it was similar to what he wore during swim practice. The promise of making 1200 dollars in just one day was too tempting to turn down, even if it meant sacrificing his pride and modesty.

Evan had visited the website SirPrize.com and found four galleries, pictures of muscular male models clad in skimpy underwear briefs, thongs, and even backless jockstraps. In some of these, the male model was posing with a female model; curiously, the female models were all completely clothed. He shook his head thoughtfully. There was a disclaimer: All photos are private. These sets were released with our model's permission to show off our work.

With tuition looming and his parents having a tough time with money, Evan desperately needed cash. His friend Josh had told him about the studio; he said he had modeled with this company before and promised it was an easy way to make a ton of bucks for just a few hours of posing with attractive models. It seemed like the perfect solution for Evan's financial woes.

Evan stepped off the campus bus dressed in a blue three-button shirt, snug denim jeans, and black leather shoes. He paused in front of the sleek modern warehouse named SirPrize above two glass double doors and nervously ran his fingers through his hair. Could he go through with it? With a sigh, he opened the door and entered the well-appointed, sleek waiting room of SirPrize Studios.

Evan nervously fidgeted in SirPrize Studios' sleek, modern waiting room. His fingers tugged at the collar of his shirt. The black leather couch beneath him creaked as he shifted his weight, echoing through the spacious lobby.

As soon as he had stepped into the office, a pretty redhead receptionist handed him a stack of forms to fill out. He quickly signed his name on the consent forms for artistic nudity and posing with another model, his hand shaking slightly from nerves.

The walls were painted a bright, crisp white and adorned with striking black-and-white photographs. All the pictures showcased male models in various poses, their chiseled bodies and confident smiles taunting Evan's nerves. From backless jockstraps to barely-there thongs, the men flaunted their toned physiques with ease. At the same time, Evan couldn't help but grimace at the provocative nature of the photos.

He flipped through a thick bound leather book titled 'The Blue Collection' on the table beside him and saw more scandalous shots. Male models completely nude with their legs spread lewdly, one with a model spreading his asscheeks and looking over his shoulder with a grin. Another showed a smiling muscular man with an erect penis smiling as a pretty redheaded woman, dressed in a white blouse and white skirt, had her hand wrapped around his waist.

Evan found the photos off-putting, put the book down quickly, and blushed. He was just here for the underwear shoots and was not interested in being part of the Blue Collection.

As Evan drank some tea that had been provided, he thought seriously about getting up and leaving. Just then, the receptionist looked up from behind her natural wood desk and said, 'Evan, if you are ready, Wendy is on her way to escort you back."

The door to the studio suddenly swung open, and a stunning woman appeared. She had a great figure with long legs and impeccably styled blonde hair. Her outfit consisted of a white V-neck T-shirt, form-fitting denim shorts, and crisp white sneakers, perfectly showcasing her perky breasts and toned bottom.

She couldn't be much older than 19, a year older than him. Somehow, this made him even more anxious.

Evan's heart skipped a beat as she flashed him a warm smile. "Hello there," she said in a sultry voice, "you must be Evan. I'm Wendy. "H-hi," Evan stammered, his eyes inadvertently drawn to the outline of Wendy's breasts beneath her thin shirt. He quickly averted his gaze, face flushing. "Nice to meet you."

Wendy's eyes sparkled with amusement. "You look so handsome and fit. Don't worry, I'll take good care of you." She winked and gestured for him to follow her inside. "Let's get you ready for your shoot."

Evan trailed behind her, trying not to stare at the sway of her hips. The studio was a flurry of activity—assistants scurried about, lights were adjusted, and makeup artists touched up chiseled models.

Wendy's voice echoed through the narrow hallway as she led Evan to a small alcove. It was sectioned off by tall black privacy screens, creating a sense of seclusion and intimacy. In one corner stood a full-length mirror, its frame adorned with intricate designs and carvings. A small table with neatly arranged grooming products sat beside it, waiting to be used. The soft scent of lavender filled the air, adding to the overall luxurious atmosphere of the changing area.

"These are the outfits you will be modeling today," she said matter-of-factly, handing him a fashionable black bag with SirPrize Studios embroidered on the front, which she unzipped.

Evan's eyes widened in surprise as she presented him with a collection of seductive fabrics. Inside were tiny white cotton briefs with a high cut back, a see-through white mesh bodysuit, a little red thong, and a backless light blue jockstrap.

"You can't be serious," he sputtered.

Wendy laughed, "These are actually some of our more conservative sets."

Evan hesitated, his face burning. Wendy raised an eyebrow. "Come on, no need to be shy. I've seen it all before. I need to see what sizes we should use."

With trembling hands, Evan began to undress. He pulled off his shirt, revealing his pale skin, and sculpted swimmer's physique. Wendy's eyes roved appreciatively over his muscled torso.

Evan fumbled with his belt, hyper-aware of Wendy's gaze. As he pushed down his jeans, his white boxers came into view. Wendy handed him a white cotton brief with an elastic band about the size of a tiny Speedo. Wendy paused and said let me get some measurements. Evan turned and stripped off the boxers and slid into the tiny white briefs; he turned with his hands over his groin.

Wendy stepped closer, tape measure in hand. "Arms up", she instructed. Evan complied, his heart racing as she wrapped the tape around his chest, biceps, and forearms, her fingers brushing against his skin. Wendy's sweet perfume and closeness aroused Evan more than a bit. She jotted down numbers, then moved lower, measuring his waist and thighs, nearly touching his balls. She moved to his calves, nodding affirmatively as she sat on her heels before him.

Wendy smiled as she looked up at him, her blue eyes sparkling as she brought her face level with his crotch; even flaccid Evan was filling out the front pouch of his briefs provocatively. She pulled out a tape measure and began measuring from his waistband down to the hem, occasionally tugging at the fabric to get an accurate reading.

She then moved on to measuring his cock and balls through the material, all the while looking up at him with admiration. "I have a feeling you're going to be one of our top performers," she said enthusiastically.

Wendy's fingers grazed Evan's skin as she adjusted the waistband, sending tingles through his body. He tried desperately to think unsexy thoughts, but it was no use. His cock began to swell, straining even more against the thin fabric.

"Wow," Wendy breathed, her eyes widening. "You're really filling this underwear up." She glanced up at Evan and grinned. "We might need to go up a size..or three'. Evan's cock stood straight out, covered in the thin fabric. Wendy reached out and moved his dick so that it pointed towards his hip. Wendy turned and let out a laugh. "Now that's what I call a SirPrize," she giggled. "Karen will have her work cut out for her today."

Evan's face burned crimson. "I'm so sorry," he stammered. "This is so embarrassing."

Wendy stood up, her body inches from his. "Don't apologize," she purred. And trust me, the camera will love it." Her hands were on his hips as she turned him around.

Evan's heart pounded as Wendy's hands roamed over his body, adjusting the tight briefs but lingering far longer than Evan thought was necessary. Her fingers traced the curve of his ass, tugging the fabric to accentuate his muscular cheeks.

"We'll definitely need some shots from behind," Wendy murmured.

"There we go," Wendy said, standing back to admire him. The white briefs strained to contain Evan's impressive package. You look stunning, Evan. "Wendy had him sit in a chair, styling his hair and even applying small amounts of makeup to his face.

Evan squirmed uncomfortably as Wendy's fingers brushed against his skin, applying a light dusting of bronzer to his chiseled cheekbones. Her touch was feather-light, but it sent tingles racing through his body. He was acutely aware of how exposed he was, his massive cock barely contained by the flimsy white fabric.

"Almost done," Wendy murmured, leaning in close. Her warm breath tickled his ear, and Evan felt his member begin to stir again. He silently willed it to behave, knowing there would be no hiding an erection in this tiny garment.

"There," Wendy said, stepping back to admire her handiwork. "You're ready for your shoot; you look great, Evan. "

She led him towards one of the elaborate sets from behind the privacy screen. Evan's heart pounded as he realized this was really happening. He was about to pose nearly naked in front of strangers.

"So, Evan," Wendy began, "do you have any modeling experience?"

Evan shook his head, feeling slightly embarrassed. He had never done anything like this before.

"That's okay," Wendy reassured him. We'll walk you through everything. You look great, and I'm sure you'll do just fine. You look amazing. I'll oil you up when you get on the first stage."

Evan felt his cheeks heat up at her words, "Oil you up," as she led him toward the first set. It was an elaborate stage with sand and a large beach scene backdrop. The sand felt cool under his feet. For added effect, there were some beach balls and a cooler filled with drinks.

"Wow, this is amazing," Evan thought as he entered the studio filled with various lights and technical props. Wendy assured him Karen would arrive soon to take photos and was just there to assist. As they began setting up beach props and adjusting the lighting, Evan couldn't help but shift nervously on the stage.

Evan caught snippets of a conversation between Wendy and a woman behind him. The woman had a sensual, husky voice and explained that she was filling in for Karen, who couldn't make it today due to illness. The woman then turned to Evan and complimented his physique, 'You really do have a great body,' she said.

He turned around and gasped, as the photographer wasn't' Karen,' but instead, he saw his Aunt Lisa standing there. Lisa was in her late thirties, with blonde hair and bronzed skin that radiated sensuality and beauty. A low-cut white blouse barely contained her ample bosom, while her tight black slacks and high heels accentuated her hourglass figure. Known as the family's wild child, Lisa had always been an artist and free spirit.

It was a shock to both of them, and Lisa struggled to find her words before asking Wendy to retrieve some lights from the office. She approached Evan with a whisper, "I never thought I would…

Evan's heart raced as he stood there, nearly naked, face-to-face with his alluring Aunt Lisa. He struggled to find words, acutely aware of his exposed state.

"I... I didn't know you were the photographer," he stammered, fighting the urge to cover himself.

Lisa's eyes roamed over his physique, a mix of shock and something else in her gaze. "And I had no idea my nephew was moonlighting as a model," she said, her voice low. "Does your mother know about this?"

Evan shook his head, feeling like a child caught misbehaving. "No one in the family knows. It's just to make some extra money for college."

Lisa paused, her lips pressed together as she considered it. Finally, she let out a deep sigh. "Well, you have the ideal physique for this kind of work. Just remember that it's just posing, and I've seen plenty of nude men in my line of work."

"Try to forget I'm here and focus on the great pay. Some poses may be challenging for both of us and can be quite suggestive. But we can handle it." She tried to reassure me with a smile, saying, "Think of it like being at the pool...well, kind of."

In her twenties, Lisa was the lead actress in an artistic X-rated film, ' Sensual Strokes,' which greatly embarrassed her family. As a result, she had become something of a black sheep, rarely spoken of except in scandalous whispers. It had been ten years since Evan had last seen her in person.

Evan couldn't help but feel uneasy as his mind raced, and he recalled watching Sensual Strokes. His uncles had talked about it frequently, sparking his curiosity to see what it was all about. As he watched, he found himself becoming increasingly aroused. He had ended up masturbating furiously to one particularly intense scene, where Aunt Lisa was being ravished on screen.

Her tan body had writhed in pleasure as she eagerly sucked the male actor's cock each time he pulled out of her tight asshole. The scene finished with the man releasing streams of cum all over her flawless smiling face and ample natural breasts.

The thought of Aunt Lisa taking photos while he was wearing next to nothing filled Evan with heat, which spread across his pale skin, leaving it flushed.

Lost in her thoughts, Lisa's expression shifted to a more professional one as she placed her hands on his hips. Her intoxicating perfume wafted through the air as she adjusted the white briefs. She methodically rubbed his chest, abs, and flat belly before turning him around and continuing her appraisal of his shoulders, back, and thighs.

Her lips were pursed appreciatively as she returned to his front, placed a hand below his belly button, and looked him deep in the eyes. Returning to the camera setup, she said excitedly, "Evan, I have a feeling this is going to be amazing."

Evan's heart pounded as he stepped onto the set, hyperaware of every inch of exposed skin. He could feel Lisa's eyes on him, professional yet tinged with something he couldn't quite identify. Was it embarrassment? Or something else entirely? Still, her professional manner and affectionate tone reassured him.

"Evan, the setup is a young man on the beach exercising," Lisa said. These will be warmup poses. "

Evan nodded, trying to steady his nerves as he positioned himself on the beach-themed set. The artificial sand felt spread beneath his large feet. He focused on getting into character, imagining the warmth of the sun on his skin and the sound of crashing waves.

"That's it," Lisa instructed, her voice steady and professional. "Now, I want you to do some stretches. Reach up towards the sky, really elongate that torso."

Evan complied, raising his arms high above his head. The movement tightened his abs and caused the waistband of his briefs to dip lower on his hips. He heard the rapid click of the camera shutter.

"Perfect," Lisa murmured. "Now bend forward, touch your toes."

As Evan leaned over, he felt the briefs strain against his muscular thighs and backside. He held the pose, acutely aware of how exposed he must look.

"Hold it there," Lisa said, her voice slightly husky. "Now, slowly arch your back. "

Evan arched his back, feeling his muscles flex with each movement. He caught a glimpse of Lisa's face behind the camera- her cheeks were flushed, her eyes dark and intense.

"Let's try some push-ups," she suggested.

Evan dropped to the ground, assuming the position. As he began the exercise, he could feel the fabric of his briefs pulling taut across his ass with each rep. The camera clicked rapidly, capturing every flex and strain of his body. Evan was already sweating from the exercises and the hot lights on set.

"That's it, Evan," Lisa encouraged, her voice calm and relaxed.

"Perfect," Lisa called out, her voice steady and commanding. "Now, lean against that prop palm tree and give me your best 'carefree beach day' look."

Evan leaned against the tree with his arms down, trying to look off in the distance and avoid Lisa's and Wendy's eyes.

"Relax your shoulders," Lisa ordered. "Just enjoy yourself." She came closer and placed her hands on his shoulders, massaging them gently. Evan couldn't help but be entranced by her sensuality: her pink lips and blue eyes were captivating, and he couldn't resist stealing a glance at her gorgeous natural tanned tits. Her shirt was unbuttoned lower than it should have been and showed off most of her gorgeous tan cleavage.

Evan took a deep breath, trying to relax as his aunt's hands kneaded his shoulders. Her touch sent shivers down his spine, and he struggled to keep his composure. He could feel his cock starting to swell in the skimpy swimwear, and he prayed it wouldn't be noticeable.

"That's better," Lisa murmured, stepping back to survey him. Her eyes lingered a moment too long on his sculpted abs and crotch before flicking back up to his face. "Now, let's try something a little more... dynamic. Lisa's breath caught audibly as she watched him through the camera lens. Lisa said, "Now turn to the side and reach up like you're grabbing a frisbee out of the air."

Evan reached, twisting his torso and extending one arm high. The pose accentuated every rippling muscle in his lean physique. He could feel Lisa's eyes roaming over him hungrily.

Evan nodded; the pose caused the already tight underwear to shift lower on his hips. He heard Lisa's sharp breath intake and...
