As the doors unexpectedly slammed behind them, Tails, Amy, Rouge, Cream and Tikal were in big trouble. The group were trapped completely in a submerged chamber deep within the winding pathways of the Labyrinth, with no air pockets to catch a much needed breath. Rouge immediately swam to the opposite end of the room and tried to open the door from below, but no such luck as she pulled and suddenly exhaled a precious glut of air. Her legs kicked as she tried to catch her breath, breasts bobbing wildly, clutching her mouth with her hand, "Mmgblk!"

Amy and Tails began examining the room around them to see if there were any means of escape, but Cream and Tikal were left frightened in the center of the room, holding onto what little air they have left. Tails felt around the walls of the ruins, feeling his lungs sting inside him, his cheeks puffing up as his member stood erect, the pressure of the water temperature and depth hugging his form tightly. As the others began scanning the room, Cream felt something tickle the back of her leg as she looked down, her eyes widened with excitement.

"Mmbbl! MMMNGBL!!" She mumbled out through pursed lips, a string of bubbles escaping from her mouth, pointing wildly at a crack in the floor, exhaling giant air bubbles at random intervals.

The group crowded around it, kneeling on the stone floor as they tried to keep the air in for the new bubbles rising from the crack. While they were excited that they weren't completely screwed, another problem came up that while there were enough bubbles to go around, the time it takes to form and rise from the crack means that some of the weaker breath holders like Cream and Tikal would have to take theirs first, and the others would have to struggle and wait possibly up to a minute waiting for air, which they didn't have.

Rouge and Amy watched expectantly at the foaming bubbles, their breasts rippling in the waters as their cheeks began to puff up, exhaling air to relieve the pressure, "Mmnngblbl..."

Tails put a hand to his chest, trying to hold down the urge to breathe a lungful of water, his fingers clawing as he let out a short gasp of bubbles, "Gblkbl!"

Cream was struggling immensely as her chest began to convulse, her pupils shrinking and dilating as the urge to take a breath grew stronger and stronger. Despite she was certain she'd get the first bubble due to age, she felt she was not ready for this kind of strain on her lungs at her age, she wanted her mommy, "Uuurghgblbl..."

However, Tikal was at breaking point. She was constantly fighting off taking a breath as she felt her pussy begin to tingle as she exhaled more air, untapping some hidden underwater fetish. She cupped her nether lips with her hand, desperately fighting off her urge to take a deep breath, but her eyes showed she was losing, "Hhrk! Nngblbhk! Hellblhbl!"

As the small bubbles frothed quietly at the cracks, no air bubbles big enough for them to inhale were coming forth, and the five swimmers were growing very hungry for air and were fighting a losing battle to hold their breaths. Cream looked on at the crack and cupped her mouth shut, trying vainly to swallow her breath down but it kept rising back to her cheeks as they ballooned to quite a large size, her blush glowing a bright red to a dark purple. "Hrrrmgblbl!"

Tails looked on at the rabbit and fretted, almost wanting to share his remaining air with her to keep her going until the bubbles came through. But as his chest rocked and his lungs seared with pain, he realised he couldn't bring himself to do it and drown for her sake, hopeful that the air bubbles will emerge eventually. Unfortunately, his struggles also brought about another odd sensation, one that only seemed to arise in these kinds of situations, the feeling of lust. He didn't know why on Mobius he felt horny underwater, but being trapped deep under the surface with no means of breathing just turned him on, his member growing rock hard with excitement.

Oddly enough, he wasn't alone as Tikal felt the same urges as her hand, previously cupping her twitching, needy pussy had slithered down to her folds and began stroking them with her fingers, letting loose a bubbly cry of excitement and pleasure, "Ahhngnblbl!!"

The others saw her pleasured struggles as Rouge began feeling the same way, watching the echidna stroke herself off was enough to get her going too, stroking her own folds and tweaking her nipples playfully as she too began to find immense pleasure in their predicament like some of her peers. Suddenly to the bat, finding escape wasn't as important anymore as her need to finger herself furiously seemed to be the only thing clouding her half-drowned mind, "Nngbl! Mmpphbl! Ooohblbl yeahgblbl~..."

Tails was finding himself stroking his erect cock at the display the two girls were giving to him, puffing his cheeks as air helplessly frothed and bubbled from his nostrils, pooling on the ceiling above them. He looked at Cream as she was on her knees, gripping her throat as she coughed out her air, failing to hold in her last lifeline, "Ahhgblk! Nnghkbl!"

He caught a glimpse of her well rounded behind and puffy labia, twitching and bobbing in the water as he stared at the prize in front of him. He could tell she took after her sexy milf of a mother very closely. Seeing as they were going to drown in this flooded chamber, what better way to go out than with a final orgasm? He paddled behind her and rubbed his member against her butt, emitting a gasp from the rabbit, "Hrrgblp?!"

As he rubbed her butt with his long fox dick, she didn't seem to resist as the feeling of drowning was feeling somewhat pleasurable to her as well, shaking her behind at him as he got the signal. He guided the head of his member into her folds as it smoothly slid in, lubricated by the waters as he gripped her thighs and let her bounce repeatedly on his member, the couple groaning in total satisfaction and pleasure as they enjoyed their last bubbly moments together as a couple, "Mmgblp! Aahngpl! Oohbl Tailbls!~~"

Out of the group, Amy was the only one not to be seemingly affected by the lust going on around them, as she watched her peers enjoy their last moments masturbating mindlessly, or in Tails and Cream's case, fucking each other until their air was drained. She almost felt the feeling to pleasure her own body, her nipples poking forth as the cool, emerald water hugged their bodies, but Amy was in too much of a panic to masturbate herself as she tried to swim and catch some of the pooled air above them. But as she kicked off the floor, her pussy convulsed uncontrollably as she was thrown into her own internal orgasm as she kicked aimlessly, clutching her throat as air poured from her tired lungs, "Nhaaaaaghblgblblh~!
As the group gave their last cries of pleasure as their air finally escaped them, their bubbly voices choked by their drinking of the ruin's waters, they felt their bodies weaken and tire. But as their drowning soon rolled around, the group started to feel their orgasms spike and flare up as they braced themselves for their final release.

Tikal was the first to go, her cum spilling forth from her pussy as it clouded in the water, her eyes widened with shock as streams of air poured forth from her weary lungs, her chest convulsing as she struggled to stay anchored to the floor, "AAAAAHHNNGBHKGBLL!"

Rouge joined her shortly afterwards, her fingers plunging into her folds and pushing forth a huge wave of cum to leak from her pussy, her breasts bouncing as her chest convulsed rapidly, "Hrrrrkaaagblkgblbl~..."

Tails and Cream were in the midst of their pleasured and horny fuck, feeling their orgasms begin to well inside them. The young fox was the first to cum inside his lover, with Cream's triggering just as Tails spilled his seed into her pussy, the young couple bubbling out their last in a unified cry of love, "NYAAAAAHGBLBLBL!~~"

Amy watched as her peers drowned around her, her body convulsing as she nearly doubled over from the pain searing in her chest, her breasts bouncing wildly as she could no longer puff her cheeks and hold in her air. She soon released her air and drowned helplessly into the water, her legs kicking and body rocking as if it had been possessed, "Aaaahgbkl! Ngghaaaaaagblblbl!~"

And even during the midst of their drowning, a lonely bubble bloomed from the frothing crack and floated in front of them, but the orgasms of the room's occupants were taking priority of their need to breathe, as it was sadly ignored. Amy caught a slight glimpse of the bubble in her drowning state, but her body was too waterlogged to react on time as it floated out of reach.

The group floated lifelessly as they relaxed from their comedown, their chests twitching as they swallowed the ruins' water around them. Their bodies soon came to rest on the floor of the ruins, Tikal and Rouge kneeling in their drowned state as Tails and Cream slumped onto the floor, almost in an unconscious embrace as his member was still stuck inside her folds. Amy slowed her kicking and soon came to rest on the floor, her vision fading to black as she swallowed on the water, "Hrrk! Nglup!"

And as they drowned and breathed their last gulp of water, the doors to the room opened up as light flooded into the dim room, opening up to show all future swimmers and explorers of the ruins the reminder of what happens when you trespass into the wrong room and give into your primal, lustful urges...
