SISTER CAR INCEDENT
There was darkness all around, a severe pain in the head, and the whole body felt numb. Slowly, consciousness returned to the two girls. The two sisters slowly regained consciousness, and slowly a rather eerie sight opened up before them - the dark blue depths around them, fish and algae swimming by. But even so, she realized where they were, she saw that the whole car was under water, and it was already seeping in, squelching around her feet
She turned to her sister, who was still unconscious after the accident, and her sister Almari was also coming to after hitting the water. When consciousness and vision returned to her, her face changed from understanding the situation, gritting her teeth and turning to her older sister with a displeased look. The two were in the car at the bottom of the lake they had recklessly driven into.
- Ouch! Alkari, what happened?
The older sister turned to her younger sister, unable to answer the question. The last thing she remembers is a long drive to the lake and a sharp slope straight into the water. It quickly dawned on Alkari what had happened as the pieces came together in her head, and she concentrated, looking around to confirm her fear. She tried to look around, but the seat belts that had kept them from flying into the car's glass kept the busty girl pinned securely to the driver's seat.
- Well done Alkari, right there!
- It was an accident! Honest!
The front of the small car was angled in the water, hood down, they were in a fairly shallow part of the lake, with flashes of light barely seeping in from above. The water had not yet reached her feet because she was smaller and sitting higher up. Also, at least for the moment, it was only splashing on the bottom of the car itself, although Alkari could feel the coldness of it.
-"It's okay, Almari, try to calm down now, okay? 
- I can unbuckle myself.
- That's good, my belt is stuck a little bit.
Alkari tried to unbuckle her seatbelt and grabbed the handle of the nearest door, pulled it hard and pushed it open, but the water pressure from outside blocked it, water crept down her legs and soaked the bottom of her skirt.
- Not good, we are deep, until the pressure is equalized...
- To equalize the pressure, the car has to be completely submerged
- Unfortunately, we'll have to wait.
Both realized the situation they were in, but they had few options. The strong water pressure from the outside kept the door closed, and the two girls remained trapped in the metal beast. The two sisters watched the water slowly rise as it flowed out of the closed doors and windows of the car. They were completely submerged and quite deep. The pressure on the doors no longer allowed them to get out, and it took time to equalize the pressure. The metal of the car creaked noticeably under the pressure, but the water penetrated very slowly. 
- So, what, we're just going to wait?
- Almari calm down, I'm sure one of the guys saw us...
- They were following us, if they had time to slow down...
- So we'll just have to wait until they get us out, so we can even have a nap.
- HERE? Your optimism will kill me before we drown!
- Well, heh, heh...
Almarie, unlike her sister, was more realistic in her prediction than her sister. Alkari tried to stay calm as she sat in her seat, even though the water was touching her panties, and the water was rising more and more. At least she was happy she wasn't alone, but she still had questions and she tried to keep her mood light and cheerful, panicking would only hurt them. Her sister sat next to her, the water moving slowly down her legs, pushing up against her underwear. 
- "Shit, my skirt! 
- You're a little wet, aren't you?
- Very funny...
In her troubled mind, she didn't realize that all her clothes would have gotten wet anyway, as the machine was slowly flooding and equalizing the pressure required complete flooding. Not that she could see since she couldn't see around her own seat.
Almari, unlike her sister, was feeling anxious, she tried to knock on the window, whimpered a little, starting to lose her own calm as the water crept higher and higher. But her attempts to open the window disappeared as soon as her sister pulled her arm.
- You're not helping the situation - Alkari said, before steeling herself and grabbing her sister's hand, trying to smile at her.
- I can't just sit there while we drown.
She wasn't really upset, just mentally denying the fact that they were stuck in a flooded car. She watched as her sister fumbled with the buckle a little more before Alkari unbuckled herself.
- Great, at least I can sit more comfortably.
The water slowly arrived, the water surface inside slowly engulfing their knees, the water soaking their skirts and panties. The two sisters were unpleasantly surprised by this situation, trying to cover themselves and move away from the water, but in vain.
- "Alkari, if we sit here and drown, there's a go... Ah!
The younger sister turned around and before she could finish her words, her sister unbuttoned her blouse and bra, revealing her tits.
- What the hell sister!
- Ah, if we stay here, we can get distracted, hehec
Almari was shocked by her sister's recklessness and fearlessness, at the depths, in a flooded car that threatened to drown them underwater, her sister found the time and inspiration to play with herself.
- The hell with you!
Alkari just smiled mockingly at her as her hand slowly pulled off her clothes. She looked down at her breasts, her nipples already sticking out with a mixture of cold and pleasure. The older sister didn't feel any fear, her mind was spinning with the need to distract herself from a bad situation and slow masturbation would be a good option for her.
Then she reached down to her breasts, caressing both breasts as slowly as she caressed herself. Goosebumps ran all over her body, her body shuddering and her mind clouded with pleasure. She let out a slight moan as my hands slid down her hips, her chest, and finally her breasts. She opened her eyes and looked down at herself, her breasts with the nipples on them erect, her hand seemed to reach out to cover them on its own, but instead my fingers were gently stroking her breasts. Slowly, the hands grabbed hold of her tits and began to massage them, causing the owner to moan softly. She clenched her fingers on her nipples and twisted them slightly, her eyes squinting in arousal. She began to lose herself in her pleasure, her mind racing with possibilities. The girl's hips began to jerk and thrust gently as she continued to move, becoming more and more sensitive with every second she massaged herself. She continued with her fantasy, swaying her hips, she began to pick up speed, fingering herself, and she also began to squeeze her own breasts. 
- Ah, why... Such a stupid feeling
- Well, little sister, if we're going to drown...
- Why not with pleasure, right?
The younger sister sat next to her, completely confused and looking shyly at her sister out of the corner of her eye, she continued to stroke and massage herself, taking some kind of perverse pleasure in the danger. Slowly, Almarie herself felt something pushing her thoughts of drowning away, and she became aroused by her sister's moans. Her younger sister's hands reached for her T-shirt, fingers sliding under the fabric to her breasts. Almarie sat up in the seat, the water already rising to her stomach, and so did her sister. 
- Ah! That feels good...
- Almari, we'll get out, but if you don't want to stay here too long...
- What's on your mind?
Alkari, distracted from herself, moved closer to her younger sister, she quickly pulled off her sister's and her own outerwear, leaving her in only her wet panties. Without asking her sister's permission, she grabbed her by the neck and pulled her into a hug and kiss. Almari could only moan in shame as her sister's tongue swirled inside her mouth, arousing her even more. 
The older sister's hands ran over her naked torso, searching for her most pleasurable places, one hand grabbed her breasts, the other slid down and reached her younger sister's panties with a splash and a gurgle. Fingers slipped into the wet fabric seeking entrance to her vagina, fingers slid across her lips and caressed her clit, making Almari moan.
- Alkari, take it easy...
- Ah, sorry, I got a little carried away.
Turning away from the kisses, the two sisters caressed each other, their hands running over their breasts, pulling and fondling the nipples of the two perverted sisters. This would never have happened otherwise, but now there was no one around them. 
The two sisters jumped and screamed with pleasure, along with their breasts, they fondled each other's pussies, but Alkari was better at it, her bigger hand brazenly penetrating her sister's inside, looking for a weak point. Almarie shivered at the intrusion and moaned, only glancing at the water coming up to her neck.
- Alkari, the water will soon flood us
- Yea, it's okay.
- We should grab some air while we can, I don't want to drown and not come.
- Good idea.
After stopping for a while and breathing heavily, they stood with their hands on the ceiling of the car, the water already grabbing their excited breasts and approaching their lips after their necks, the cold water felt on them, the nipples became even more sensitive from the cold. She tilted her head up as the water reached her neck. She took a deep breath, trying to stay calm.
- Shit, this is not good.
- Calm down, I'm here, I won't leave you.
- Should I try to open the door?
- Only after you... blublebl
Alkari fell silent as the water reached her lips and approached her nose. Almarie stood by her side, just watching worriedly as her sister and she disappeared into the water, but her older sister encouraged her with a smile. A moment later, the water engulfed the car completely, leaving the two girls floating in zero gravity inside. Alkari pushed herself away from the ceiling and awkwardly swam to the door, grabbing the handle and frantically trying to open the door, but in vain. Alkari let some air out of her lips in frustration at her failed attempt to open the door, she floundered in the water adjusting her breasts so they wouldn't get in the way. The door silently refused to cooperate. Almari tried the same thing but got the same result.
Moving away from the door, they accidentally bumped into each other, losing some of their air in surprise. Turning to each other, they didn't expect anything, but continued their perverse act. Almarie, accepted the invitation, pressing her lips to hers and kissing her deeply, she rolled onto her, wrapping her arms around her sister's waist and holding her close.
Alkari reached down with a smile to her sister's legs spreading them, then her tongue found her clit and her sister moaned releasing a portion of air from her lips as she let out the breath she had been holding, the tongue's invasion of her clit and its stimulation, causing intense pleasure to overwhelm any rational thoughts in her mind. Alkari slowly licked her clit, flicking her tongue, and then gently massaged it. She gurgled and moaned as the bubbles crept up her sister's thighs before splashing out and lingering on the ceiling of the car. She twitched slightly, and her hand instinctively went to her sister's head, clutching her hair as if urging her to keep going, to never stop, not for anything in the world. Alkari paused her licking and lifted herself up a little, once she was in front of her sister's clit, she brazenly released a strong stream of bubbles onto her sister's pussy.
Alkari then pressed her lips to the clit and sucked gently, and Neri's mouth gaped open at the intense stimulation. She put her hand over her mouth, but moans and whimpers escaped her throat as she began to squirm. She tossed her head from side to side, her pleasure making it impossible to hold her breath. Bubbles burst from her nose as she felt a burning desire to breathe. 
She was losing more air than her sister, and she was afraid of it, afraid of cumming and drowning before her sister. Alkari pulled away from eating her clit, turning to her sister. Her sister whimpered and writhed in slow suffocation, opening her eyes with force to her sister. Alkari knew that her sister wouldn't last long, so... Alkari opened her mouth and pressed into her sister's again in a kiss, giving some of her air into her sister's lungs, the younger sister sucked in as much air as she could, but most of it slipped through their lips and rose to the surface as a cloud of bubbles. Only when her sister stopped squirming and calmed down did she open her lips.
"Grobrbll! Mmrgbl!!!"
Alkari leaned back, exposing herself to full view, her legs spread open to reveal her cute, slightly hairy pussy, inviting her sister to take the last ride for them now. The younger sister hesitated but feeling that the portion of air would not be enough, she made a similar movement.  Once she was completely naked, she swam over to her sister, where she placed her legs between the younger girl's. Even just by being close to her, Almari could feel the warmth coming from the older girl's heart. 
"Mmmm... Mmmm!" moaned Almari, trying to communicate with her sister.
With their legs pressed together, feeling the warmth of the two pussy, they began to rub each other. Their bodies turned into a twitching, tangled mess of Yuri's debauchery. Alakri's hands remained glued to Almari's. Her body already felt exhausted. It tingled with lust and squirmed on her sister's clit but did little else. Both kept their pussies connected. Alakri looked back at her with a thoughtful look. She giggled weakly before smiling. 
"Mmmmm...!!!"
The way they moved their hips precisely, the ecstasy that appeared on their faces when, with each friction of pussy against another pussy, they lost air in the form of small gasps from their closed lips. Every second she held her sister in her arms, their bodies pressed together, she felt her skin stretch and slide and her body respond with a crazy pleasurable warmth.
"Urp... Mmf... Grbl......"
The tension in her muscles grew and grew until her back arched. Almarie's mouth gaped open, she gargled the penetrating water down her throat and coughed out the last of her air in short bursts, pleasure blocking her airway. As her lungs contracted, she felt and knew it would soon be over. With the two sisters' hearts pounding furiously in their chests, pushing the remaining air in their bodies and the surge of adrenaline, they both began to tense up, preparing to end the painful breath-hold. Alkari saw the condition her sister was in. Almari was left convulsing in the rhythm of the kicks, trying to feel her chest and cover her mouth in any way possible, even if she was swallowing water at the same time.  But she didn't care, it felt good to her and no one saw it. She gurgled a burst of air, releasing a large cloud of bubbles.
Soon, the younger sister let out a gurgling moan as she made one last push to reach orgasm. Muscles trembled throughout her body as Almarie thrust forward violently. Their breasts slammed against each other as Alakri's tongue slipped into her sister's mouth one last time. They struggled inside in a last kiss before drowning, fire searing through their crotches and burning the rest of their bodies with a strange warmth. At that moment, Almari's eyes opened. The same flame that was burning inside had spread to her, and only one thing could extinguish it. As blue began to cover their faces completely, all that filled their lungs was the cold and unpleasant water of the lake. 
"Mmm-MMMPH! MmmmMMMPH!!~"
Juices flowed from their pussies and mixed with the water. This force alone was enough to tear the two girls apart, leaving them floating and choking on the water. Their bodies were completely exhausted from sex and suffocation. Cries of pleasure filled the water but did not let go of the girls, preoccupied with the resulting spectrums of emotion and pleasure, two tired bodies quenching from fatigue and orgasm, and their minds slowly disappearing in that pleasure. Almarie's chest contracted only a few times before the rest of her body relaxed, and with no sense of danger or anxiety in her tired mind, she inhaled slowly, slowly, swallowing the water into her.
"Hrbrbrll... Mmorbl!"
"This was so much fun! Haha... maybe we should go, huh? " Alkari thought as she looked at her naked sister, who was spasming furiously and squirming with every movement of her pussy against her sister's. Her sister was quickly drowning in pleasure and no longer stopped to breathe in water. She gurgled and whimpered, and with each whimper the bubbles became less and less until there were none left. Her body gave up and now no bubbles were coming out of her mouth, on the contrary her mouth constantly began to swallow the water inside. Each gulp made a blue tint appear on her face.
gakkhkhkhkh.......hel...helppp.....blblbl...."
With a few last little gurgling gulps, her arms and legs dangled aimlessly in the water. When Almari finally drowned, her sister put her hands on her. Alkari was not far from the same state, exhausted from lack of air and mutual caressing, her body slowly gave up and she began to swallow water into her lungs. Her head became heavier, but she didn't care, pleasure and drowning, now a smile of pleasure covered her blue face, her mind accepted this fate and she only awkwardly enjoyed her orgasm drowning next to her sister. Her chest throbbed slightly, still trying to expel the water from her overcrowded lungs, but with each heavy breath she took in more water. Each gulp was accompanied by a dull moan and a gurgling sound in her throat. There, in their naked embrace, the feeling of having her sister by her side made the two sisters feel even more joyful about drowning together. Closing her eyes, Alkari pulled her younger sister into her arms and held her head to her chest.
"Mmmph... Brbrll... Grk....."
Eventually, her body's movements froze and the struggle ceased, the only movement left being the tiniest heaving of her chest and twitching of her stomach. Alkari pating her drowned sister's head as her consciousness slowly faded away, and with a last painful gurgle she passed out, shaking her whole body. Remaining in the water prison, the two sisters were unconscious, both drowned from water inside their breast and the pleasure derived from mutual caressing and sex. The two drowned bodies lay in each other, waiting for rescue.
