﻿Moonlit Serenade: An Underground Trip And Hot Spring Rendezvous


“Were are we going exactly?” Asked the curious yet excited pink hedgehog to her Hyper-sonic blue boyfriend who was carrying her as he raced through the trees of the Mystic Jungle. 


“You’ll see.” He simply said, wanting to surprise her tonight. 


It’s been two months since the beginning of their relationship and the ‘lovely couple' have been doing pretty good for themselves. Life together has been nothing but good fun and one exciting adventure after another. Nowhere was out of the question for them as they enjoyed exploring new places and discovering new things, which was especially easy since one of them was the fastest thing alive that is capable of getting them anywhere they wanted/needed to be in a matter of seconds. 


Tonight was no different as they had spent the first half of it exploring a newly discovered underground water cavern. 


WindyValley Mountains: 4 hours ago


When they had arrived at the cave entrance, they marveled at it’s beauty. Mostly Amy though, Sonic was already walking forward after a quick look. It was huge with all kinds of rock formations decorating the ground, ceiling, walls and pathway leading deeper into the cavern. Some were simple stalactites and stalagmites, others were shaped like spiral spikes twisting upwards and downwards, columns of rock were scattered in different parts of the cavern entrance, the walls were smooth and rippled down and inwards, sheets of flowstone made a makeshift path leading into the main cavern with a gentle stream of water–no higher than the soles of their shoes–flowing down it, the entrance itself was shaped like an giant mouth that seemed both intimidating and welcoming at the same time as the immediate inside was large and wide. Blue crystal like gems imbedded into the ground and walls reflected the light from outside giving the entrance a soft glow.


Amy followed closely behind Sonic as he walked into the cave. She kept darting and looking all over with sparkles in her eyes and her mouth wide open. Every generation that twinkled caught her eye, each spiral felt brittle when touched, the walls felt smooth and cool, each step she took in the stream of water flowing down the main path made small ripples in it. 


Sonic chuckled at her apparent wonder. “You know we’re only at the entrance right?”


“Huh?” She turned to him, not quite catching what he said. 


“We’ve seen way cooler cave entrances then this.” He said matter-of-factly.


“Oh, I know.” She replied before turning on her heel and bending down to stare at a gem shaped like a tear drop.


He smiled amusingly while rolling his eyes. “but~ ” 


“But–” She continued. “That doesn’t make this one any less dazzling to admire.” She said with a smile, now looking at the gems that decorated the cave walls. 


“You say that about everything.” He reminded her. 


“And it’s true every time.” She says smugly without turning. 


He chuckled softly. “Sure, whatever you say.”


He continued on into the cave. “Come on, I’m sure it gets better inside.” He called out to her. 


She turned around and sprinted up to him to not fall too far behind. “You sure?”


He gestured to the cave walls. “The cave itself says so.”


She took a look at the cavern walls (and the cave entrance in general) and noticed how everything seemed to point inwards. 


The flowstone path and stream were obviously moving into the caverns but so was everything else; the rock formations became more packed together and uniformly aligned the further deep they got into the cavern, the crystals that were spaced out slowly became more tightly packed together, the pathway became narrower and the light became dimmer. 


“Wow your right!” She said in acknowledgement. “I wonder what it’s like deeper inside.”


He stopped to stand beside her and took her hand in his. “Only one way to find out.” He said in anticipation–his grin widening and ecstatic.


She giggled at his enthusiasm. “Hehe… Welp what are we waiting for?” she squeezed his hand before taking steps forward, pulling him with her. “Let’s go!”


As the traveled deeper underground, they watched as the walls narrowed down the further in they went, slowly becoming a tunnel of ripples, the path got slimmer and the stream rose higher now reaching past the soles of their shoes, the rock formations from the entrance no longer surrounded them–the tunnel to narrow for any to form, the light got dimmer and further away the deeper they went, the only light source now becoming the soft glow of the blue gems in the walls.


“Starting to get a little cramped.” Sonic said calmly, already used to narrow tunnels that only got smaller. 


“Yeah, it’s… kinda unsettling.” Amy said shakily, not fond of tight spaces. 


“Hey relax,” Sonic reassured once he felt the slightest tremble in her hand. “It‘s gonna be alright.”


“Are you sure?” She asked quicker than she intended to, trying to mask her growing discomfort but her nerves betrayed her. 


“Absolutely, after all–” He let off a toothy grin. “I’m here so nothing’s touching you.”


She stared at him for a moment before giggling “Yeah your right,” she leaned up and pecked his cheek. “I’ve got nothing to worry about.”


She leaned against his shoulder as the continued further into the cave. The glow of the gems casting a soft blue hue over them.


“Not as long as I have you by my side.” She said lovingly. She had her eyes closed knowing Sonic wouldn’t let anything happen to her. 


His grin softened into a tender smile and his hand tightened around hers. 


Before long they saw the tunnel slowly get brighter; the gems’ glow slowly got brighter and fuller, small patches of Fluorescent fungi began to pop up more and more and soon, light was visible from the other end of the tunnel. 


“Looks like where at the end,” He looked over at her, smiling softly. “Ready to see what this place REALLY has to offer?” He asked, already knowing her answer. 


She returned his smile with a wider one. “With you, Always.”


They entered the main cavern and had their breath talked away at what they saw. 


“WWWWOOOOOOOWWWWWWW!”


“Whew~ now THIS is what I call Beautiful.”


The central cave of the entire cavern was far larger than the entrance and was at least as big as Cathedral. The walls had multiple large holes leading to other caves, the gems they saw were twinkles compared to the large sapphire crystals that decorated the walls and ground of the cave, ground that fell in large–uneven steps, almost like plates of earth had been placed on top of one another and then broken at their centers leading down into the large pool in the very middle of the cave. Several streams of water flowed from different cave openings down the layers of rock and into the central pond, bioluminescent plants and fungi were all over the floor–most abundantly around the pool giving it a whitish-green glow as it reflected their lights along with the moonlight that was shining down from the opening above. 
Said opening was directly above the pond and framed the night sky like it was a window into space. 


It was beautiful, otherworldly as some would say. Both hedgehogs made their way down the water covered path, Amy rushing ahead of Sonic to the very center of the cave, stopping just shy of the pools edge. 


“This place is INCREDIBLE!” She marveled at her surroundings, spinning in place to get a complete look at everything. She stopped and bent down to a patch fungi growth that were surrounding a gorgeous glowing flower that was shaped like a dandelion. Her wonder growing by the second–as well as her smile and the sparkle in her eyes. 


Sonic, finally catching up to his energetic girlfriend chuckled sincerely at her excitement and placed a hand on his hip while raising an eyebrow. “You really do get excited over everything don’t chya'? We’ve been to all kinds of places like this already.” He lightly teased her, finding her easy-to-amaze habit quite funny if not cute and endearing. 


She turned her head to him with a bashful smile. “Hehehe I guess you have a point,” she admits. “But I mean come on, look at this place.” She stood back up and gestured all around them. “How can I not, it’s Gorgeous!” She exclaimed with one of the biggest smiles he’s seen. 


He grinned, folding his arms while looking around. “Hey, I’m not saying you’re wrong to do so, I’m just saying with the amount of times we’ve seen places like this,” He stopped and looked at her. “Wouldn’t you have gotten used to it? I mean, Ya tend to act like it’s your first time seeing a place like this.” He said plainly. 


She smiled, closing her eyes while letting out a soft breath. “Well if you ask me, it doesn’t matter how often you see or experience something.” She opened her eyes to look fondly at him. “If it makes you happy or excited or elated or anything like that,” She bobbed her head side to side as she spoke, swaying her hips as well, “Then why keep it in? It would be better if you just let it out for the world to see.”


She turned around and opened her arms out, spreading her legs. “And this place–just like all the other places we’ve been to–makes me feel so amazed at what the world has to offer that I–just. can’t. help myself but be amazed.” She then turned back to him with the same fond smile. “Just like how I can’t help myself when I’m around you.”


Sonic was left shocked by her openness, the irony of which is not lost on him. since he was just teasing her for still reacting to things she should be used to. 


Now here he is reacting to the same thing he’s been exposed to the exact same way. Left speechless by her unabashed openheartedness that he has seen countless times. 


And yet he still can’t help but marvel at her like he always does. 


“heh.” He lets out a soft chuckle, muzzle turning red from her cuteness. 
‘God I’m a hypocrite.’ The thought flew through his mind as easily as she did. 


But then another thought flew through his head. One brought up by both Amy’s little speech about always being amazed by what’s around her and he thought. 
‘Huh, wait a minute, if she’s always amazed by places like this then...’
A smile slowly grew on his face. ‘Maybe,’


“Uuuhhh Sonic?”


“Hm.” He’s pulled out of his thoughts as she called out to him. 


“What cha' thinking about~ ” She asked in a sing-song. Innocently smiling at him, wanting to know what was making him smile so much.


“Oh, nothing just… ” His smile returned after making his decision. “I just remembered, I know somewhere else we could visit tonight.” He continued. “Just like here.”


“GASP–! REALLY?!” She jumped at revelation, eyes filled with literal sparkles (or probably just the light of the cave). 


Sonic chuckled at her giddiness. “Yep, really. And trust me when I say,” he gave her his signature thumbs up while flashing his well-known smirk and wink. 


“You’ll love it.”


Mystic Jungle Deep Wood: Present 
He was certain she was going to love what he had in store. 
‘And on the perfect night for it too, Amy’s gonna love this.’ 


The night air was crisp and clean, carrying the faintest hint of pine from the surrounding forest as Sonic dashed along the winding jungle path, Amy cradled securely in his arms. Her laughter rang out like wind chimes as the world blurred around them, the blue hedgehog's speed making the stars streak like silver ribbons across the sky.  


“Ooooohhh I just can’t wait to see what it is.” Amy giddily said as she clung to his shoulders as he took a sharp turn. “Are we close by yet?!” She asked with excitement even more present in her voice. 


Sonic smirked, his emerald eyes glinting in the moonlight. “Relax, Ames. We’ll be there soon?”


“Oooohhhhhh, come on Sonic just tell me Please!” she pleaded with him, kicking her impatient legs.


“Woo-hoho, easy there Ames. Wouldn’t want us to tumble over now would ya?” He said regaining his balance from that near fall she almost caused. 
‘And I’m usually the impatient one.”


“Oops, sorry.” She apologized with an embarrassed smile. “But could you just tell me.”


“Amy–”


“Ppppllllllllleeeeeeaaaaaassssss?” She added a wide toothy smile at the end. 


He smiled at her attempts to persuade him, they were cute in all honesty. “Sorry Amy, gotta keep it a surprise.”


“Hump, fine then.” She pouted as she turned her head forward and furrowed her eyes but nestled closer, her arms looping around his neck. 


The cool night breeze ruffled through their quills as they had reached the deepest parts of the jungle, the sounds of civilization had long since faded behind them.  


After a few more minutes of running, Sonic slowed to a stop at what seemed to be a dense growth of tress with vines blocking the path forward. 


Sonic placed Amy down on her feet and moved in front of the vines, grabbing them like a curtain–ready to pull open. He turned to her with an excited smile of his own. 
“Alright, you ready?”


She nodded, her energy matching his. He pulled open the vines and her eyes and mouth flew open. 


“Oh. MY. GAIA!”


Before her, hidden within the dense foliage of jungle trees, was the hot spring—its crystal-clear waters shimmering under the full moon's glow. The surface rippled gently, reflecting the starry sky above. Steam curled into the cool air, carrying the faint mineral scent of the springs.  


The grass clearing surrounding it was flush and green, filled with life and lights from the fireflies flying around. Beautiful flowers were dotted here and there; daisies, dandelions, some white roses and violet irises.


The spring itself was nestled right up against a large boulder that curved around it, creating a sort of backrest of smooth rock. 


“Sonic, this is BEAUTIFUL!”


He grinned. “Yeah, I know,” He cockily rubbed his nose. “Found it during one of my runs. No idea where the hot waters coming from but hey,” He shrugged as he didn’t really care for it’s origins. “Good place to come and relax.” 
‘Especially on a night like this.’  With the full moon hanging heavy in the sky, it was nothing short of magical.  


Amy wasted no time, slipping off her gloves and dipping a hand into the water and a sigh of contentment escaped her lips. “Ohhh, that's perfect.” Closing her eyes to take in the warm feeling of the water. 


“Well then what are you waiting for?”


She opened her eyes to find Sonic already in the hit spring, gloves and shoes on the ground beside her. 


“Get in.”


She blushed, taking off her clothes nervously. It’s not that she’s not used to being naked around him, he’s seen everything at this point naturally. It's that she didn’t even notice him get in in the first place. 


Once she had taken off all her clothes and was as bare as the day she was born, she folded them neatly and placed them on the ground a few feet away from the spring so as to not get them wet. 


The moment she sank into the spring, the warmth enveloped her like a warm embrace from the sun itself. Amy sighed, leaning back against the smooth rocks as the heat seeped into her muscles, melting away all the stress in her body she wasn’t even aware of. 


Sonic slid over and settled beside her, his arm brushing against hers before wrapping around her–pulling her close against him, their wet fur rubbing together.


“This feels nice.” She stated, eyes closed as she enjoyed herself. Her head resting against his chest, a small smile of content clear on her muzzle. 


“It really is.” Sonic agreed. “I mean, it’s not like the cave’s but–”


“Your right, it’s better.” Amy cut him off without turning over to him. 


“Really?” He questioned her, looking down with curiously raised eyebrow. “How so?”


She nestled in closer into his chest. “Because this is our special cave, which makes it even more amazing.”


He smiled at her statement, glad he went through with his idea. 


They sat in silence for a while, just enjoying the heat of the hot springs, how the moon's glow painted their quills with shimmering silver highlights and each others company above all else. 


The water was so clear that even beneath the surface, their reflections danced alongside them, distorted only by the gentle ripples their movements created.  


Amy opened her eyes halfway and looked up at Sonic, her cheeks flushed from the heat. “So… do you come here every night?”


He was still looking down and smiling at her, eyes half lidded as well. “Nah, only when I need to unwind,” His eyes softened, a flash of desire flying across them “Or when I wanna impress someone.”


She giggled lightly. “Hehe, And how many ‘someones' have you brought up here?” She asked quietly, desire also flashing across her eyes. 


Sonic turned to her fully, his other hand rising out of the water to turn her face to look at him fully as well. “Just one.”


Amy's breath hitched as his fingers traced her cheek, his touch sending sparks through her despite the warmth surrounding them. 


He leaned down and pressed a kiss to her lips, holding her close as the heat from the springs stored their hormones. 


Her free hand reached up, brushing a droplet of water from his cheek. 


Breaking the kiss left them both breathless as they stared into each others eyes. “You know... ” She started, “This would be a really romantic place to... ” She trailed off, voice getting lost in the rising heat. 


She didn’t need to say anything anymore anyways. 


Sonic's eyes darkened, his hand moving from her cheek to her waist–tightening just slightly. “Yeah.”  


And then she was moving, shifting until she straddled his lap, the water swirling around them in gentle waves. Sonic's breathed a hot breath as her hands settled on his shoulders before slowly moving to cup his face, her body pressing flush against his. The heat of the springs was nothing compared to the heat inside them.  


She kissed him deep and slowly, hands moving from his face to his quills, fingers tangling in them as the water rippled around them.  


Sonic’s hands took their place on her waist, and then further down to worship her soft pink rear. 


Her moans escaping her throat only to be muffled by his lips moving against hers and then eventually his tongue.
She wrapped her arms around his neck, pulling him closer to her–deepening their kiss–her chest getting pressed harder against his, the friction made evermore enjoyable by the hot springs.


As they continued to pleasure one another, their bodies became more restless and soon their arousals began to make themselves known. 


Amy broke the kiss once she felt her lover’s member against her thigh. She looked into his eyes, want clear in those emerald orbs. 
“Sonic~”


They both knew what the other wanted and were more than ready to give. 
“God, you’re beautiful~” He breathed out as he held her up to a line himself with her, once he did he brought her down slowly and began to enter her, inche by inche. Their shared moans mixing in the air as they joined together again. 


Once she had taken all of him into her, she began moving her body softly and he was already meeting her halfway in rhythm with her.


Amy threw her head back and let out her sounds of pleasure while Sonic continued to stare at her ample breast, plump and round as ever and now glistening in the moonlight thanks to the hot springs. He took her left breast and began to suck on her nipple, sending a wave of pleasure through her body. 
“Oooohhh Sonic~ yes…… please, don’t stop~”


Amy held his head closer to her chest and took his other hand and placed it on her other breast and held it as he began playing with her right nipple, moaning as Sonic licked and played with her breasts. 


She moved faster on his member, the feeling of him entering and leaving her flower sending shocks through her spine, made more prevalent as he made effort to match her as well, the surface of the springs continually rippling from their love making. 


Sonic soon released her breast from his mouth and trailed a line of kisses up to her neck, his pace quickening as he did so. Amy’s hands never leaving his quills or left hand, holding on to them as her body shook from ecstasy. 
Her chest rose and fell rapidly as she couldn’t control her breathing, coming out in short gasp of air as her body bounced on his. 


Sonic soon brought his lips right beside hers and Amy’s grip on his quills tightened, ready to hold him in place. He took the hand she held to her chest and caressed her face with it before gently turning her to look at him directly. As soon as she did he kissed her and pushed his tongue into her mouth, she moaned into his mouth as she reciprocated the kiss, the taste of his lips driving her even further. 


They settled into their rhythm and let their desires carry their bodies further into bliss. The heat of the springs making their already sweaty bodies more aroused, the water splashing all around them becoming another sound of their pleasure. 


After several minutes, they could feel their climaxes approaching. Amy Broke the kiss they were still enraptured in and hugged him tightly. Sonic’s hands instinctively took their place on her hips, ready to help ride out their orgasms together.
“Sonic~ I’m so close… ”


“I can tell, you’re squeezing me so tight… inside right?” He asked knowing the answer already. 


“As always…. My darling Sonic~ ” She closed her eyes and rested her head on his shoulder. 
Sonic began to thrust his hips as fast as he could while Amy clung to him. She repeated words of encouragement and pleasure as her orgasm got closer and closer, the waters of the spring now splashing more violently as they got closer to their end. 


Finally, Sonic reached his limit and erupted inside of Amy’s tunnel. He groaned as he continued to thrust into, shooting thick streams of Cum into depths of her womanhood. 
Amy let out choked moans as he pumped her full of his Cum, the sensation pushed her to the limit and soon she had reached her orgasm, her fluids mixing with the water of the spring as she released them. 


Once they had finished riding out the climax, they sat there in the hot spring to catch their breath. Amy still on top of Sonic, his penis still throbbing inside her, neither dared to move, still enjoying the contact they were sharing, the warm waters doing their part in calming them down. 


Amy nestled her face into his neck and smiled at the feelings that were swirling around inside her (both emotionally and physically inside her). 
“That was amazing~ ” She sighed contently. 


Sonic had an arm lazily wrapped around her, his other arm resting on the outer edge of the hot spring. A similar smile on his face. 
“It sure was.”


Amy pushed herself up to be eye level with him and cupped his face, Sonic held her waist as she pressed their lips together, soft moans and purrs leaving their throats. 


When their lips finally parted, they pressed their foreheads together, basking in the moment they just shared. 


“We should definitely do this again.” Amy whispered. 


Sonic chuckled, before readjusting her to be resting her head on his chest before replying. “Yeah, definitely.”
