Sable whispered, "You sure we're allowed to be here, Mabel? I'm sure we're kind of breaking and entering doing this..."
Mabel silenced her with a kiss to her sister's lips, their tongues meeting before breaking off, "Sure, nobody's gonna know we're here anyway. Now come on, I need you~..."
The two were locked in a passionate kiss before Mabel shifted her weight, the couple falling into the pool with a loud splash. They broke the kiss as the cool water of the pool hugged their bodies tight, their nipples growing rigid. Sable broke the embrace and surfaced with a squeak, "I thought the water would be warmer!"
Mabel surfaced beside her and smiled back, "That's not gonna be a problem. So, you ready?"
As Sable was hugged from behind, her sister's legs wrapping around her waist, she gave a warm smile back and cooed, "Mmm, my baby sister's growing up~..."
The two kissed again and dove under the surface, swimming to the deep end of the pool together as Sable paused, waiting for her sister to prepare herself. Sable too got ready, leaning back with a wry lick of the lips as she spread her legs wide open. Mabel took the opportunity to get her sister nice and wet for the occasion, so leaned down and slipped a tongue into her folds, making her sister gasp in reply, "Ghaahlkgb!"
Sable then started shifting her sister's weight, signalling she wanted to return the favour as Mabel rotated her body until she was floating upside down, the older sister gripping her younger sister's thighs and licking at her own folds, "Ooooohgblblbl~..."
Soon, the two felt sufficiently more prepared for the task ahead and got into place. Sable spread her thick legs open first, allowing her sister to dock, her pussy lips grinding against each other. Sable stifled a need to gasp as bubbles streamed from her pursed lips, Mabel smiling in reply as she began riding her sister's pussy. The two shared bubbly, passionate cries as they scissored together, Mabel groping her breast with one hand and fingering herself with the other, Sable riding her sister's fingers, "Ah-Nhaagbkglaaah!"
The two spent what felt like an age grinding and bubbling away, their minds frazzled from the crazy amount of pleasure being given to one another. Mabel's breasts bounced in the water with each grind of her lips against her sister's, Sable's own breasts bobbing in the water, unsecured by her grip unlike!e the blue hedgehog in front of her. The two were lost in a sea of pleasurable ecstasy, so much so they failed to notice a strange mechanical buzzing above them.
As the two neared their climaxes, Mabel leaned back, her quills flowing as she threw her head back, "Oogblbl~... I'bm cubgling!"
Sable felt her eyes roll back as she felt an orgasm stir inside her, her body losing all control as she embraced the growing warmth inside her.
As the two hilted their breaths, they both came into the water simultaneously and let out bubbly cries of immense pleasure, "Nhaaaaaghkbgblbgl!!~"
The couple came for quite a while, their bodies convulsing and rocking as they shared their seed, breasts bobbing and legs kicking wildly, their folds leaking cum as it clouded in the water. Soon, the couple were completely spent as they pulled themselves off one another. Sable floated weakly as she fingered herself, the last few drops of cum leaking from her. Mabel swam to her and gave her another bubbly kiss before the couple pushed off the pool floor and swam to the surface.
That is, until Mabel hit something solid, "Mmgblbl?!"
Mabel felt something plastic above her, the lack of lighting making it hard for her to see but recognised the material and bubbled in panic, "Thebl poolbl cobergbl! We'reghl tragbbled!"
In their haste to scissor one another made them fail to notice the pool cover had automatically closed on them, their forgetfulness and haste forgetting to remind them to set the automatic cover off. Now the sisters were trapped under the cover as they scrambled to find a means of escape before they drowned completely, cum still leaking from their pussy lips as they almost connected to each other.
Mabel scratched at the surface, her hands pounding uselessly at the covered surface as she tried to push an air pocket open, but the material was too heavy for her to shift effectively. Sable tried to help by helping her push but to no avail, the two sisters were stuck under the pool cover as they drowned helplessly, "AAAAGHBLGBKGBLBL!!"
As they drowned together, they felt the sudden pinches and itches of drowning mixed with the convulsions in their chest and lungs caused them to start orgasming again, cupping their mouths to prevent letting go of any more air, but as Sable found that their situation was futile and they were to drown together, she plunged her fingers into her pussy and opened the floodgates as she came again into the water, "NNNGHGBLBL!!"
Mabel noticed her older sister orgasming and swam up to her in a panic, "SABLEGBL!"
In her last waking moments, Sable felt her sister try and keep her alive as she breathed air into her lungs, but didn't want to see her suffer any longer. With a smile, she plunged her fingers into her sister's pussy as she drowned in the midst of a massive orgasm, "AAAAGHBLGBKGBLBL!!"
Sable watched as her sister breath in pool water as she twitched and convulsed in her arms as she slowly but surely drowned in her arms, "Sorry, sis. Had to be done..."
With a last gulp of pool water, Sable faded completely as she drowned alongside her sister, the couple locked in a tight embrace as they came to rest on the pool floor, Mabel lying atop her sister peacefully as they quietly slumbered in the cool pool waters, the moonlight above them giving them an almslt ethereal glow. While Sable didn't want to drown at all tonight, she had to admit...
She wouldn't have wanted to go any other way.
