"I came here to win / I'm already there / I'll get the blue ribbon like I'm at a state fair…"

Britina's latest album could still be heard from her Kimmunicator as one teen hero walked around the home, ensuring that she really did have the entire Possible household to herself. She would let nothing get in the way of her time alone if she could help it.

Front door locked? Check. Confirmation that Ron will be with Felix all night? Check. Neutralised tweebish and Wade-ish security cameras? Check.

Satisfied that everything was as right as it was gonna be, Kim let out a sigh of relief and headed for the family bathroom. Her heart rate was already increasing in anticipation.

She firmly closed the bathroom door behind her, full lips caught in between her teeth and a gleam in her eye.

She turned on the tap, letting the water run over her fingers until it reached her ideal temperature. She plugged the tub to let it fill, and she could already feel the slow build-up of steam in the room.

While she waited for the tub to fill, Kim began disrobing, taking the opportunity to massage her breasts and tweak her nipples as she did so. She was so going to enjoy this bath.

Spring Break was in a few days. For most high schoolers, that was a week-long guaranteed downtime. She, however, didn't have the luxury of thinking all of her time would be free, so whenever nights like tonight presented themselves, Kim relished in them.

The tub was halfway full now, so she added her favourite bath soap scent from Shower and Skin Works and watched the bubbles build up. Her lips stretched into a wide, genuine smile.

Bubbles, and bubble baths in particular, have been a favourite of hers ever since she and Ron were little. The colourful refraction of images within the multitude of spheres gave her a sense of whimsy she didn't naturally possess, and she and Ron would always try to make the silliest faces and props out of the condensed bubbles.

She turned off the tap when the water reached the perfect height and picked up some of the bubbles in her palms. She placed them on her face, taking care to avoid her eyes, and tried to morph them around her mouth. She turned to the mirror to see the result and laughed out loud.

Standing there in only her underwear with her vibrant auburn hair starkly offsetting the white bubble beard on her face, she looked like a Rated-X Santa Claus. She briefly contemplated snapping a pic and sending it to Ron (and maybe another one without the bubbles… or maybe with bubbles in choice locations) but nixed the idea when she remembered that would ping Wade too. 'Gorchy,' she grimaced to herself.

She doffed her clothes and finally sunk into the water. Kim let out breathy groan at the warmth on her skin, and her subsequent deep inhale brought her the airy citrus and mint scent that she loves. Her beard blended in with the rest of the bubbles on the surface of the water, and she briefly imagined having a beard long enough to fill an entire tub. She chuckled to herself, making a note to herself to tell Ron about that musing. He'd get a kick out of it.

"I don't vibe with your 'tude / Don't try to step to me / If you are all you say you are, uh, see you 'n' three…"

Kim sang along to the next Britina song as she made a topography out of the bubbled surface on which she could imagine battle strategies. Just as she was using her knee to make a mountain, her Kimmunicator rang.

She let herself sigh before picking it up. "Sitch me, Wa-oh, Britina!"

"Kim!" Britina greeted jovially. In the background, Kim could see Britina was flying in her private jet. "What's the dilly?"

Sensing this was purely a social call, Kim relaxed back into the water. "I'm just spankin'! I have the house to myself tonight, and I'm actually listening to your album right now! It is so the bomb."

"No you are not!" Britina enthused. "I'm so glad to hear that! Your opinion means a lot to me."

"Aw, you're sweet," Kim grinned. "Not that I don't love catching up with you, but what's the sitch?"

Britina's dark eyes sparkled with excitement. "Album sales are through the roof, so I was finally able to cinch a yummy mansion in Beverly Plains that I had my eye on. I saw on your website that you're going on Spring Break soon. Why don't you and your new beau stay at mine for the week? It's the least I can do after you helped me avoid that major fashion faux pas in Amsterdam!"

"No big!" Kim dismissed. "Nothing that a bicycle spoke and a naked mole rat with teeth like shears can't fix! And I know you would have done the same for me."

"And that's exactly why I want you to help me warm my house! Oh, Kim, please say you'll come? You won't have to pay a dime, and you don't even have to pack clothes! I'll handle transportation and everything. Just say yes!"

Kim deliberated for a moment before smiling. "With a wicked offer like that, how could I say no?"

Britina squealed. "Poppin'! I'll get someone to pick you up right after school on Friday. Can't wait!

"See you soon, Britina!"

"For sure! Enjoy your bubble bath," she jested with a wink before cutting off the connection.

Kim blushed a little when she realised that she had that whole conversation with nothing but bubbles to cover her modesty. She blushed even harder when she realised she kinda liked it.

She leaned her head back against the tile and closed her eyes as she trailed her hand down her body. She squeezed her waist, palmed at her rear, and played with her curls, gradually getting closer and closer to her throbbing center with each movement.

Her legs unwittingly spread as Kim continued her ministrations until she finally let herself slip her forefingers past her lips. She bit down as she massaged herself, imagining that it was Ron's thumb circling her clit. She was sure that even without the soapy water, her fingers would be slick with her juices.

Her other hand started at the base of her head, lightly tugging at her hair before moving down to her breasts. She rubbed at her chest, tweaking her tits just enough to effect a twinge that shot straight down her torso to her core.

So engrossed was she in pleasuring herself that she didn't notice when the last note of Britina's album played, leaving the room silent except for Kim's mewls and the displacement of water by her arm as her fingers increased their intensity.

… But it wasn't working! All of the rubbing and pinching and flicking, and she was barely scratching the itch.

She abruptly stopped and flung her arms against her sides, paying no heed to the water and bubbles spilling over the side of the tub.

Kim frustratedly stared at the ceiling, contemplating if it was worth it to get out of the tub to get her vibrator from her room, when she noticed the showerhead.

The detachable showerhead with eight different jet settings.

She grinned lecherously.

Kim carefully stood up in the bathtub and immediately felt her nipples stiffen from the abrupt temperature change. She turned on the water just enough to test the settings, and she found the one with the most powerful pulse. 'Lucky number 7 it is,' she grinned to herself.

She unplugged the drain to account for the extra water, laid back down in the tub, and directed the showerhead right at her opening.

Much better.

Kim spent some time just playing with herself, rubbing her clit between her forefingers as she angled the stream of water up and down her slit. She stretched one of her legs to hook on the rim of the tub to open herself up to as much pleasure as feasible.

She brought her hand back to cup her breasts, imagining what Ron would do if he were here. She longed for his hooded brown eyes, his panting breaths as he touched her, the warmth of his manhood pressed against her thigh as he took control of the showerhead for her…

Kim then imagined Britina perched on the edge of the sink, hand buried in her crotch as she watched the two of them in the tub, and Kim finally got her release.

She called out into the empty bathroom and rode the wave for as long as she could, encouraging herself with both hands in and around her fluttering lips. Finally, she slumped into the tub, totally spent.

Slowly, the sounds and sights of the outside world registered in her mind. She shivered as she realised the water levels in the tub was far lower than it was at the beginning of her bath; her body was splattered with patches of bubbles. The showerhead lay forgotten on the floor of the tub from where she let go in her preoccupation, still shooting water at the shower wall. A quick look outside the tub revealed a soaked and bubble-ridden bathroom rug.

She self-deprecatingly mused to herself that this is exactly what happens when she only gets the house to herself once in a blue moon.
