The next morning, Charlotte woke up with a pep in her step, her usual energy undimmed by the bizarre turn your life had taken. You, on the other hand, felt the weight—or rather, the lack of weight—of your new existence pressing on you. Or, more accurately, pressed against her. You were still her thong, nestled snugly against her skin, and you hadn’t even fully processed the events of the previous night before she was already moving on to the next thing.
“Oliver,” she said, her voice cheerful as she stood in front of the mirror, brushing her long blonde hair. “I’ve decided we’re going to spin class today!”
“Spin class?” you asked, your voice muffled by the fabric of your new form. “Charlotte, I don’t think—”
“Oh, don’t be such a downer,” she interrupted, waving her hand dismissively. “It’ll be fun! Plus, it’s been ages since I’ve gone. And you’re the perfect workout buddy now, aren’t you?” She grinned at her reflection, her eyes sparkling with mischief.
You wanted to argue, to tell her that being pressed against her ass for an hour of intense exercise wasn’t exactly your idea of fun. But before you could say anything, she was already slipping into her workout gear. Your objections died in your throat as she pulled on a pair of tight black leggings, her enormous, jiggly ass stretching the fabric to its limits. You could feel the heat radiating from her skin, the softness of her curves pressing against you as she adjusted the waistband.
“There,” she said, smoothing out the leggings with her hands. “Perfect fit, as always.” She turned to the side, admiring her reflection, and you couldn’t help but feel a strange mix of awe and anxiety. Her ass was huge, the kind of asset that turned heads wherever she went. And now, you were intimately acquainted with every inch of it.
Charlotte grabbed her water bottle and headed out the door, the tightness of her leggings leaving no room for you to move. You were trapped, your face pressed firmly against her backside, and there was nothing you could do but hold on for the ride.
The spin class was located in a trendy studio downtown, the kind of place where everyone seemed to know each other and the music was always pumping. Charlotte greeted the instructor with a bright smile and claimed her bike near the front of the room. As she adjusted the seat and pedals, you could feel the anticipation building in the air.
“Alright, everyone!” the instructor shouted, her voice booming over the music. “Let’s get ready to sweat!”
The class started, and within minutes, you were in hell. Charlotte’s ass moved rhythmically as she pedaled, her hips swaying with each rotation of the bike. The heat from her body was overwhelming, and you could feel the sweat beginning to build, soaking into the fabric of your new form. Her massive cheeks jiggled with every movement, their softness pressing against you in a way that was both suffocating and strangely exhilarating.
“Charlotte,” you muttered, your voice barely audible over the music. “This is… a lot.”
“What was that, Oliver?” she asked, glancing down at you with a playful smirk. “I can’t hear you over the music!”
“I said, this is a lot!” you repeated, louder this time. “I don’t know how much longer I can take it!”
“Oh, come on,” she said, laughing as she increased the resistance on her bike. “You’re doing great! Just think of it as a bonding experience.”
A bonding experience? You weren’t sure how being pressed against her sweaty ass for an hour could be considered bonding, but you didn’t have time to argue. Charlotte was in the zone, her focus entirely on the workout, and you were along for the ride—literally.
The class continued, and the intensity only increased. Charlotte’s ass became slick with sweat, the heat and moisture making you feel like you were suffocating. Every movement of her hips sent a jolt through your fabric, the sensation of her softness pressing against you becoming almost unbearable. You could feel the fabric of her leggings clinging to her skin, the tightness of the material amplifying every jiggle and bounce.
“Charlotte,” you groaned, your voice barely a whisper. “Please, can we stop?”
“What’s that, Oliver?” she asked, her tone teasing. “You’re not giving up already, are you?”
“I’m not giving up,” you protested. “I just… I can’t breathe!”
“Well, don’t worry,” she said, her voice dripping with amusement. “I’ll take good care of you. Just hang in there, okay?”
You wanted to argue, to tell her that this was not what you had signed up for. But before you could say anything, the instructor called for the final sprint, and Charlotte pushed herself to the limit. Her ass bounced and jiggled with every pedal stroke, the heat and sweat making you feel like you were being smothered. You could barely think, let alone speak, as the class finally came to an end.
Charlotte slowed her bike to a stop, her breathing heavy as she wiped the sweat from her face. She glanced down at you, her smirk widening as she saw the state you were in.
“Well, that was fun, wasn’t it?” she asked, her tone light and playful.
“Fun?” you repeated, your voice hoarse. “Charlotte, I thought I was going to die!”
“Oh, don’t be so dramatic,” she said, laughing as she peeled off her leggings. “You’re fine. Besides, I think you’re starting to get used to this whole thong thing.”
“I’m not sure I’ll ever get used to this,” you muttered, your voice muffled by the fabric of your new form.
Charlotte just smiled, her eyes sparkling with mischief as she gathered her things. “Come on, Oliver,” she said, her tone teasing. “Let’s go get some water. You look like you could use a break.”
You wanted to protest, to tell her that you needed more than just a break. But before you could say anything, she was already heading for the door, her massive ass jiggling with every step. You could only sigh, resigned to your fate, as she carried you out into the world once again.
