"You want me to do what?" Brim's eyes widened as he leaned back against the plush pillows on the bed, his tail flicking in surprise. Jemma held up the magazine with a glossy page titled "50 Spicy Ideas to Rekindle the Romance!" She had a mischievous glint in her eye that Brim knew all too well.

Jemma giggled nervously, her cheeks tinged with pink. "Well, I read this article about these potions. They're totally safe and reversible. And it said, you know, sometimes trying something new can really bring a spark to a relationship." She held out a tiny vial filled with a shimmering blue liquid, the same shade as the one in the magazine.

Brim took the vial in his slender otter paw, examining it closely. "And how do you know it's safe?" He eyed her skeptically, his whiskers twitching.

Jemma waved the magazine in the air. "They have rave reviews from all these happy couples!" She watched as Brim rolled the potion between his fingers, the light dancing off the shimmering surface. "C'mon, Brim, it'll be an adventure!"

Brim sighed dramatically, a smirk playing at the corners of his mouth. "Okay, okay. I guess it would be a little fun to be more adventurous." He tossed the vial into the air, catching it deftly. "But if I turn into a tiny otter, you better not squish me."

Jemma's eyes lit up, and she extended her pinkie finger out, waiting for him to wrap his around it in a promise. "Pinkie swear, I'll keep you safe," she said with a playful grin. The anticipation grew thick in the room, and Brim felt his heart quicken. He looped his pinkie around hers, their digits locking together in a silent agreement.

With a deep breath, Brim uncorked the vial and downed the potion in one swift motion. The blue liquid glided down his throat, leaving a cool, tingling sensation in its wake. Jemma's eyes widened, her face a mix of excitement and trepidation as she waited for the transformation to take effect.

As the seconds ticked by, Brim felt a strange warmth spread through his body, his limbs tingling. He looked down and watched in awe as his paws and tail grew smaller and smaller. "Whoa, it's working," he murmured, his voice pitching higher as his body continued to shrink.

Jemma's eyes went wide with excitement. She leaned back, her thighs spreading apart slightly as she watched the transformation unfold. Her hand slipped under her skirt, her fingertips tracing the softness of her fur before sliding into her panties. She began to explore herself gently, her breath hitching as Brim grew tinier by the moment.

Brim felt his heart racing as he shrank down to the size of a small toy. His body was now so light that he could feel the fabric of the bed shifting beneath him as Jemma's hand moved with increasing urgency. Her scent filled the air, a sweet and tantalizing aroma that sent a thrill down his spine. He watched, his eyes fixed on her, as she grew more and more aroused, her fingers working steadily.

With one swift movement, Jemma scooped him up and brought him to eye level with her soaking wet pussy. The sight was overwhelming; he had never seen her this way, so open and large. He felt a rush of desire that was unlike anything he had ever experienced before. His little otter cock grew hard, straining against his fur.

Jemma spread her velvety paws, exposing her swollen pink folds to him. "Look at me, Brim," she instructed, her voice thick with desire. "I want you to see just how much I want you." He nodded, his eyes wide, unable to look away from the slick, inviting warmth of her sex.

With trembling excitement, she brought him closer, inch by inch. Brim's heart hammered in his tiny chest, his cock standing at attention despite his miniature size. He could feel the heat radiating from her, smell the musky sweetness that filled the air. His body was a live wire, every nerve ending on fire.

Jemma's eyes bore into his, a wild hunger in their depths. With a gentle yet firm push, she inserted him into her wetness. Brim gasped, the sensation of being engulfed by her warmth unlike anything he had ever felt. Her pussy walls clung to his small form, the softness and wetness enveloping him completely.

He found himself adrift in a sea of sensation, surrounded by the velvety softness of Jemma's inner folds. Her love juices coated his tiny body, allowing him to glide and swim with ease, much like he would in the waters of their favorite river. The walls of her vagina rippled and contracted around him, sending waves of pleasure through his body. It was as if he had been miniaturized to fit perfectly within her.

Jemma's eyes fluttered closed, a low moan escaping her lips as she began to rock her hips, creating a gentle current for Brim to ride. His little otter hands paddled through her warm, wet depths, exploring every nook and cranny with curiosity and wonder. The potion had not only shrunk his body but had also heightened his senses, making every stroke and squeeze feel amplified.

The walls of Jemma's pussy were like a velvety playground, each contraction sending ripples of pleasure that Brim chased with eager strokes. He could feel his tiny otter cock growing more and more sensitive with every moment, the tightness of her grip on him felt amazing.

As Brim explored the depths of Jemma's warmth, his paws came into contact with something new - a firm, yet yielding wall that he hadn't felt before. It was her cervix. His eyes went wide with realization, and a thrill of excitement shot through him. This was uncharted territory for both of them.

With a mix of curiosity and anticipation, Brim felt around Jemma's cervix, the softness of it making his heart race. He traced the smooth surface, his tiny fingers caressing the delicate tissue, feeling the pulsing of her arousal.  Then he found what he was looking for.  He felt the entrance to her womb, her sacred place.  The hole was so small, but so was he.

Taking a deep breath, Brim aligned his miniature body and thrusted. The pressure was intense, like trying to fit a cork into a bottle. Jemma's eyes snapped open, her breath catching in her throat as she felt him pushing against her deepest barrier. "Oh my," she whispered, her voice a mix of pleasure and surprise.

With a gentle yet insistent push, Brim's cock began to penetrate her cervix, stretching it just enough for his small form to pass through. The sensation was unlike anything either of them had ever felt, a mix of tightness and yielding that sent jolts of electric pleasure through both of their bodies.

Jemma fell back on the bed, her chubby belly jiggling. Her paws found her swollen black nipples, pinching and pulling them in time with his movements. The sensation of his tiny body making love to her cervix was unbelievable, a feeling of fullness and connection that went beyond the physical. Her eyes rolled back in her head, and she let out a deep, guttural moan.

Brim's movements grew erratic as he felt his climax approaching. The tightness around him was unbearable, and he knew he couldn't hold on much longer. His strokes became more desperate as he approached the edge. His little otter body was a blur of motion, lost in the overwhelming sensation of her warm embrace.

Jemma's moans grew louder, her hips bucking against him as she matched his frenetic pace. She could feel his tiny form pulsing within her, his body tensing as he approached the point of no return. The sight of him, so small yet so powerful, was more than she could handle. Her own orgasm was building, a crescendo of pleasure that threatened to drown them both.

With a final, desperate thrust, Brim came inside her, his miniature body convulsing as he filled her with his seed. The feeling of his release was like a burst of electricity, sending shockwaves through Jemma's body. She threw her head back, her fur standing on end as she reached her peak. Her pussy clenched around him.

But as she came, her mind went blank and her primal instincts took over. Her body, acting on its own accord, did something neither of them had anticipated. Her cervix, which had been tight and unyielding just moments ago, suddenly expanded, pulling Brim in deeper.

Brim felt himself being drawn into Jemma's warm, velvety womb as if by a vacuum. He couldn't stop, couldn't fight it. He was being sucked into her womb, his tiny form slipping past the barrier and into the uncharted waters of her depths. The pressure was intense, but the thought of the act was so overwhelming that he could only let out a high-pitched squeak of ecstasy.

Jemma's eyes flew open, her pupils dilated as she realized what had happened. "Brim!" she gasped, her paws reaching down to feel her now empty pussy. "Oh my god, Brim!" Panic began to set in as she realized he was no longer in her pussy, but inside of her womb.

Brim's tiny body was adrift in the warm, enveloping fluid of Jemma's womb. The walls were smooth and pulsating, the feeling eerily similar to the gentle rhythm of the sea. His otter instincts kicked in, and he began to swim, his tail propelling him. Brim was in a serene bliss.

Above him, Jemma sat up in shock, her paws trembling as she felt the emptiness where Brim once was. "Brim! Are you okay?" Her voice echoed through the vast space of her body. She leaned back, trying to listen for any sign of his response.

To her amazement, she felt two faint taps against her cervix from the inside. It took her a moment to understand what it could mean. Could he be...? "Oh, you clever otter," she murmured with a smile, realizing he was trying to communicate. She felt the taps again - one, two. It was like a miniature Morse code, tapping out his message against the doorway to her womb.

Jemma's paws shakily reached down to her pussy, feeling the wetness and the slight bulge of her belly. "Are you okay down there?" she asked, her voice a mix of amusement and concern. Again, she felt the reassuring two taps. Her mind raced with the reality of the situation - her tiny lover was now swimming inside her womb.

Curiosity piqued, she leaned closer, whispering sweet nothings into her own pussy, trying to convey comfort and love. "Do you want to stay in there a little longer?" Brim's tapped twice. The idea of keeping him there, nestled within her, was oddly thrilling.

With a sigh, she laid back and stretched out on the bed. "Alright, have fun in there, darling," she murmured. "I'm going to take a nap." Her eyes grew heavy with the weight of the day's excitement, and she closed them, her breaths deepening into the rhythm of slumber.

As Brim felt Jemma's body relax, the gentle waves of her breathing lulled him into a tranquil state. He continued to explore her womb, his tiny paws brushing against the velvety walls. But soon, even his boundless curiosity could not fight off his own fatigue. The potion had taken a toll on his small body, and he felt a profound weariness seep into his bones.

He found a cozy spot nestled between two folds of her womb, the perfect size for his tiny frame. With a yawn, Brim curled up, feeling the warm, comforting embrace of her body all around him. The gentle throb of Jemma's heart lulled him to sleep, his tail wrapped around him like a blanket.

The next day, Brim awoke to the sound of Jemma's voice, muffled but still soothing. He knew it was time to leave this cozy haven. He swam back towards the entrance to her cervix, feeling the walls of her womb pulse gently with her movements.

As he approached, the once inviting opening now seemed tight and unyielding. He pushed against it, feeling the muscles of her cervix contract around him, as if her body was reluctant to let him go. Brim's tiny paws pressed against the slick tissue, his body straining as he tried to force his way out.

Jemma felt the sensation of his struggle, the pressure against her insides both alarming and thrilling. She had read that the potion could have unpredictable effects, but she never imagined he'd be stuck inside her like this. "Come on, baby," she cooed, her voice filled with a mix of concern and excitement.

With a final, desperate push, Brim felt himself slip out of her warm embrace. He emerged, gasping for breath, his tiny otter body coated in a mix of her fluids. Jemma's paws immediately went to her pussy, feeling the odd sensation of his exit.

"You're out!" she exclaimed, her eyes lighting up with joy. She scooped him up into her palm, inspecting him for any signs of distress. He was a bit soggy but otherwise unharmed. "Are you okay?" she asked, her voice filled with genuine concern.

Brim nodded, his cheeks flushed from the ordeal. He looked up at her, his tiny voice barely audible. "I'm great!  That was the best sleep of my life." He took a moment to compose himself before a wicked smile spread across his face.

Jemma couldn't help but laugh, the tension in the room dissipating as she felt the wetness of her hand from his birth fluids. She held him closer to her face, her eyes sparkling with mischief. "Well, it's time to get you back to your usual size, my little otter."

Holding the second vial, she uncorked it and a pungent, spicy scent filled the room. "Here, drink this!" she said, dropping a single drop of the growth elixir into her palm. Brim looked up at her, his tiny body trembling with excitement as he leaned forward and licked at the potion.

The liquid was potent and fiery, burning a path down his throat as he swallowed it. Jemma watched, her eyes glued to his body, as he began to stretch and expand. His fur ruffled and stood on end as he grew larger, his paws and tail elongating until he was back to his usual size.

"Wow," Brim exclaimed, his voice deep and strong once more. He sat up, the vial now dwarfed by his hand. "We have got to do that again sometime." His grin was infectious, his eyes sparkling with the thrill of the experience.

Jemma couldn't help but giggle at his enthusiasm. "I would love that," she said, placing the vial safely on the nightstand. "We'll definitely have to try some more adventures." She leaned in and kissed him, her panda's fur tickling his nose.

The room was quiet, the only sound their panting breaths mingling with the gentle rustling of the sheets. Jemma whispered, "Hey Brim," her voice barely audible. Before he could ask what was on her mind, she pulled him into a tight embrace, her chubby body enveloping his thin frame. "I love you," she murmured into his ear, her breath warm and soft against his neck.

Brim returned the embrace, feeling the comforting weight of Jemma's larger body around him. "I love you too, Jem," he whispered back, his voice a bit shaky. The experience had been more intense than either of them had anticipated, but it had brought them closer in a way they never thought possible.
