Yuzu's heart jumped into her throat when Mei grabbed her hand. This was the first time Mei had voluntarily moved during these nighttime activities, and it was to prevent her from retracting her hand out of her shorts.

Her stepsister had an iron grip on her wrist. Her palm was pressed against Mei's pelvic mound, held down by the shorts' waistband.

Mei released the wrist and laid her hand on top of Yuzu's. Slowly and deliberately, she pushed Yuzu's fingers inside her.

Yuzu moaned when her two fingers slid inside her stepsister's center, her head falling forward on the crook of the girl's shoulder. The sensation of Mei's wet heat around her fingers was incredible. Her heartrate picked up and blood pounded her through her body.

After guiding Yuzu's fingers between her legs, Mei stopped moving. The only indication of Mei being awake was her shallow breaths, her chest rising and falling rapidly.

Several moments passed. Yuzu wondered if maybe Mei was back to pretending to be asleep. Did Mei actually want her to carry on and then in the morning just act like nothing happened? Yuzu would have giggled at the absurdity of the situation, if she wasn't so horny she couldn't think straight. Nope, I can't last one more night.

"Mei," she murmured softly against the brunette's neck. She felt the girl hold her breath.

"Mmmmhhmm?" was the sleepy response.

"Are you asleep?" Yuzu inquired.

"Hhhrmm, yeah," Mei mumbled.

"Oh okay." Yuzu said very slowly. She shifted closer, and moved her leg on top on Mei's own. "It's just that you're very wet."

To demonstrate, Yuzu moved her two fingers that were inside Mei very slightly. Just enough to bring Mei's attention to the area. Yuzu heard Mei's breath hitch in her throat.

"My hand accidentally slipped inside your pants," Yuzu whispered conspiratorially. She withdrew her fingers an inch, and then gently slipped it back in. It was like dipping her fingers in wet silk.

Mei hummed again, but this time it sounded a tad strained.

Yuzu started to stroke between Mei's legs at a languid place. She loved the smooth, velvety drag of her fingers on Mei's warm, slick walls. She was delighted at the shudder that swept through her stepsister's body.

"Imagine my surprise at what I found between your legs."

A choked sound came from Mei, a cross between a deep exhale and an aborted moan.

"You're positively soaked, Mei." Yuzu stroked her stepsister harder. She pushed her fingers into Mei with more force. Mei's walls clenched around her.

"Hhhnngghh."

"So I don't know if you were really asleep." Yuzu pulled her fingers out halfway and then buried them to the hilt. Again, and again. Deeper each time. Yuzu wet her bottom lip with a swipe of her tongue when she felt Mei get even wetter, a fresh gush of arousal coating her fingers.

"Hhhmphff."

"Does this happen a lot when you're asleep?"

"Hhhmmyes."

"Were you maybe having a wet dream?"

"Y-yes…"

"Dreaming of me?" Yuzu angled her hand so that the heel of her palm hit Mei's clit with each stroke.

"Fuck," Mei whined. "Yesss..."

"Was it a good dream?"

"Oh god, yessss."

"Did I make you feel good?"

"Hhhngghh," Mei's hips started to rock against Yuzu's hand, thrusting up to meet each down stroke. "So," thrust— "very," thrust – "very," thrust – "good."

Yuzu's thumb pressed down to mash her throbbing clit in small, tight circles.

A desperate mewl was torn from Mei's throat as she ground her hips against Yuzu's hand, trying to chase the friction on her clit that was causing the coil of tension in her core to wind tighter and tighter. She was getting close— just a little more—

Yuzu suddenly completely withdrew her whole hand out of Mei's shorts. The younger girl gave a broken cry, the breath ripped from her chest at abruptly being pulled back from the precipice.

"Mei, I think you should take off your shorts. This is going to be much easier if you didn't have your bottoms." Yuzu announced as she bent over the side of the bed and looked for the switch of the nightlight. She flicked on the light, illuminating the area of their bed with a dim orange glow, casting long shadows into their room.

Mei looked up at Yuzu who was looking down at her, propped up on hands on either side of her head. She stared up at her older sister, confusion and bewilderment clear on her face. What the fresh hell? What kind of game is this?

Yuzu on the other hand, wore a teasing, smug look on her face.

Mei placed her hand flat on Yuzu's face because she wanted to wipe the shit-eating grin on it. Grunting, she used Yuzu's face to push the girl off of her, and brought herself to a sitting position. Looking the blonde dead in the eye, she crossed her arms across her front, grasped the bottom of her camisole and pulled it off over her head in one smooth motion, and sent it sailing into a darkened corner of their room. Still not breaking eye contact, she drew up on her knees and divested herself of her shorts and panties in much the same efficiency.

Mouth agape, Yuzu stared at her stepsister. Sitting naked surrounded by a sea of sheets, the nightlight creating shadows that caressed her beautiful curves, Mei looked like a priestess to some ancient goddess of love and beauty. Yuzu's eyes raked over her flawless skin, her supple breasts, the graceful curve of her waist. The flare of her hips with the deep V, drawing the eyes to the apex of her thighs, which lay, to Yuzu's mind, the gates to heaven. The blonde wet her lips, suddenly feeling parched.

But it actually wasn't Mei's naked body that had the most devastating effect on Yuzu. It was The Look in Mei's eyes saying she was done playing games and Yuzu better take care of her right the fuck now.

"They're off," Mei said in an impatient voice. She leveled an intense gaze at her stepsister for good measure.

The words set Yuzu's body aflame, and she felt like she was about to have a religious experience. Desire coiled in her gut, lust clouded her mind. She intended to defile her pure, perfect stepsister. Right here in the bed they shared. Her vestal virgin on the altar of her wildest Sapphic fantasies. All the blood rushed to her pelvic region, sending waves of pressure pounding on her clit.

Yuzu crawled towards Mei sitting at the head of the bed. Emerald eyes locked on dark amethyst orbs before they lowered onto Mei's mouth. She sealed their lips together as she pushed her stepsister back against the pillows.

Yuzu swept her tongue along her stepsister's lower lip, and the raven-haired girl parted her mouth with a small moan. Yuzu gently explored the inside of her lips and even darted a little deeper to touch her teeth.

Upon tasting her stepsister's flavor, a needy moan bubbled up from Mei's chest and she opened her mouth wider. Yuzu's warm tongue slipped inside her mouth, and pleasure scattered across her senses. Mei wrapped her hand around the back of Yuzu's neck, pulling her closer, and she pushed out her own tongue to engage her stepsister's. Their tongues circled each other, slick, warm, and tasting of the keen tang of passion.

Yuzu's hands were roaming Mei's bare body, stroking her flushed skin, running down her sides. Mei moaned against Yuzu's mouth when the blonde's hands found her breasts and squeezed, reverent. Yuzu's thumbs swiped the hardened nipples back and forth, making tingles shoot down to her stomach. The ache was starting to build in her core, and her usual reaction to this was to squeeze her thighs together, but this time her stepsister was lying between her legs.

Pleasure surged in her loins when Yuzu felt her stepsister's thighs squeeze her midsection, and she thrust her hips in response.

Mei broke their kiss as her head fell back and a small "hhnnh" fell from her lips when Yuzu's pelvis pushed up against her bare, sensitive center. She grasped Yuzu's shoulders, and when her stepsister decided to keep repeating the action, Mei dug her nails into the soft flesh. Yuzu thrusted into her, harder each time. With each slam against her center, her clit was stimulated, shooting electricity down to her toes.

"Fuck," Mei panted. "Yuzu, please, please." She wasn't entirely conscious of what she was begging for, just that her stepsister was the one who could give it to her. Her whole body felt like a live wire, nerves singing in places she didn't know existed.

Yuzu stopped her thrusting and lowered her head and pressed it against the other girl's neck. "Don't worry, Mei. I got you." She promised in a low, silky voice. "I've waited a really long time for this."

Yuzu let Mei ponder those words as she started to move down the brunette's body. She traced Mei's jawline with soft lips and the gentle graze of teeth. Yuzu laid open-mouthed kisses on the delicate column of Mei's neck before gently biting the tender spot right below the pulse point and then sucking.

Mei gasped with pleasure at the sensation of Yuzu biting her neck before a nagging thought filtered through the fog of arousal. She laid her hand on the blonde's chest and nudged gently. "Baby, no," she whispered tenderly in Yuzu's ear. "No marks. Not there."

The term of endearment made Yuzu's stomach flop. She didn't want to stop sucking on her stepsister's neck like she was trying to get to the chocolate center of a hard candy, but she acquiesced to the request immediately. She knew the student council president wouldn't be happy in the morning if she had to go to school with her neck covered in hickeys. No sir. Besides, it didn't mean she couldn't taste and mark her exquisite skin in other places.

Holding herself up on her palms on either side of Mei, Yuzu blazed a trail down Mei's front with her mouth, alternating between wetly kissing and sucking on skin. She started with giving a gentle nibble on Mei's collarbone and then tasting the skin with her tongue, then applying suction. Mei's hands were tangled in her blonde locks, gently holding onto her head as she kept moving down her chest. After each new mark was sucked into place, Yuzu lathed the red spot with her tongue before trailing her lips to the next delectable patch of skin.

Before long the blonde's mouth arrived at wisps of hair covering the mound between Mei's legs, the ones she had started stroking during the witching hour two nights ago. Yuzu closed her eyes as she slowly nosed her way down Mei's mound, inhaling deeply. The keen tang of Mei's scent entered her nostrils, coiling around her mind, making her dizzy with unbridled lust. The idea that she made Mei so wet that she was dripping onto their bedsheets sent high-octane arousal to race through her veins.

A gasp was torn from Mei's throat when Yuzu laid a long firm lick along the length of her sex. The blonde then started lapping all over, and Mei realized that Yuzu was trying to lick off all the wetness between her legs. Heat bloomed on her face and she hissed, "Yuzu, what are you—"

"You taste delicious," Yuzu snapped her head up and stated matter-of-factly. Giving Mei what could only be described as bedroom eyes, she continued, "I think I found my new favorite flavor. So I hope you'll feed me well going forward. And not let me starve."

Mei was speechless for a few moments as she tried to wrap her head around her stepsister's…pick up lines? If that's what you can call it? Deciding that she had more pressing issues than admonishing Yuzu for her terrible lines, she simply grasped the back of the girl's head and pushed it back down to her waiting sex.

Mei felt the rasp of Yuzu's tongue lave over the seam before moving to her folds. The warm tongue explored every moist corner of her folds, the heat in her core building with each sensuous lick. The intrepid tongue moved down and licked around her entrance, and the raven-haired girl sucked in a mewling breath. Yuzu plunged her tongue inside, and she was pierced with a sharp lance of pure pleasure.

As Yuzu thrust her tongue in and out, a lust-filled moan rumbled through the brunette. Her hips started to stutter against Yuzu's face as she attempted to spear herself on that tongue. Mei fisted the sheets with one hand, and the other threaded through blonde hair. Yuzu's tongue fucking into her felt so unbelievable good. The drag of Yuzu's slick tongue as it plunged into her wet hole sent warm tingles crawling up her chest and to her extremities. With each rock of her hips, she pulled at Yuzu's face, burying the girl's tongue deeper inside her, she just needed a few more strokes and she was going to—

The blonde head between her legs disappeared. One moment she was mainlining sex hormones and the next second the IV was forcibly ripped from her, and Mei felt herself come crashing down from the high. She bit back the scream at a certain gyaru who apparently thought it was amusing to tease her mercilessly. She opened her eyes to glare at her stepsister, who sitting back on her heels with an impish smile on her face. Yuzu gave her the bedroom eyes again and made a big show of sensually licking her lips.

"Mmmmm I think I could get addicted to your taste, Mei. It's even better than I ever imagined. See, when I came up with this plan—"

Yuzu never got to finish talking about how she had devised the strategy for tempting Mei during the last couple of weeks, methodically increasing each touch and caress in carefully planned increments because Mei lunged at her.

Mei straddled Yuzu's hips and pinned her hands beside her head.

Yuzu was momentarily stunned at finding herself on her back, but then she closed her eyes at the delicious weight of Mei on her pelvis. Her hips bucked once involuntarily, and the brunette responded by squeezing her thighs and bearing down. Muffled sounds of pleasure slipped from both their lips.

Yuzu opened her eyes and gazed up at the raven-haired beauty on top of her. Her stepsister's eyes were almost indigo as they bore into hers.

Mei released her grip on Yuzu's right wrist and brought the hand to rest below the blonde's navel. Still locking eyes with the girl beneath her, Mei unfurled Yuzu's fist and gripped her middle and ring fingers. She raised her hips up slightly and lined up Yuzu's fingers against her entrance, still holding on to the blonde's hand. Just before lowering herself on the digits, she said in a voice that brooked no argument, "Yuzu, I want you to fuck me until I come all over you."

And with that Mei bottomed out on Yuzu's lap. Yuzu's whole body clenched at the sensation, and she wasn't able to contain a whimper. The blonde's free hand reflexively went around Mei's waist to hold her close as she moved on top of her. Her occupied hand was mostly pinned under Mei, and she didn't have a lot of range of motion. But that didn't seem to bother Mei in the least because she seemed like she was deriving a lot of pleasure in fucking herself on Yuzu's fingers. Yuzu leaned back a little to look down at their centers pressed together, and she was momentarily mesmerized by the sight of her fingers buried in Mei's pussy. Oh my god. Even down there she looks so fucking pretty.

Mei increased her pace and she was practically slamming into Yuzu's hand. Her breasts started to bounce, drawing Yuzu's attention to her heaving chest.

Yuzu leaned forward and captured a nipple in her mouth. She closed her lips around the areola and gently sucked. Mei threw her head back and a long drawn out moan fell from her mouth. Yuzu circled her tongue around the erect bud, and her stepsister's breathing turned shallower, coming in soft pants.

The idea to tease her stepsister flitted across her mind, and Yuzu opened her mouth to release the nipple, but Mei simply plunged her fingers into Yuzu's hair to hold her head in place and thrust her chest up to the blonde's mouth. Yuzu happily acquiesced and started suckling on the hard nipple with enthusiasm.

The blonde concentrated in committing this moment to memory. The insanely gorgeous Aihara Mei was straddling her lap, fingers tangled in her hair, riding her hand, hard. Her other hand was wrapped around the back of the heiress' waist, locking them in an intimate embrace where their skin slipped against each other's.

Yuzu shifted the angle of her wrist so she could move her hand in the confined space of her lap. Achieving a little wiggle room, she drove her hand into Mei's pussy, plunging her fingers in and out. She felt Mei getting wetter, and her arousal started to slick on her palm.

A look of absolute ecstasy came over Mei's face, and the moan that she made was so loud and sounded so pornographic that panic suddenly seized Yuzu and she slowed her hand. "Mei, not so," she begged. "Not so loud. You'll wake up Mama!"

"Mama drank at least five Asahis tonight. She's sleeping the sleep of the dead right now," Mei hissed. Her pupils were blown out as she stared at Yuzu's face in the dim light, and she slowly rotated her hips in a small circle.

Arousal shot through Yuzu at the blatantly sexually provocative move. With a groan, she leaned forward to shift her weight onto her knees, letting Mei slip off her lap and land on her back. She couldn't hold back anymore and continue to tease Mei. Her only concern was to make the raven-haired girl under her orgasm so hard that she'd forget her own name.

Mei was panting softly as she tried to retain control of her body. The pace that Yuzu set between her legs was making her mind go slowly blank. Pressure was building low in her belly from Yuzu's fingers slamming into her, almost too intense to bear, but somehow her hips rocked to meet Yuzu's thrusting hand, almost of their own will. Then Yuzu's fingers found a delicious spot inside her that shot pleasure up her spine, and she keened. The blonde rubbed that patch inside her again and again, and it tripled the pleasure thundering through her body. Her walls clenched around Yuzu's fingers as the pressure became too much, pressing for release. Her back arched off the bed as her body quaked, and she saw stars erupt behind her eyelids. Loud, uncontrollable moans fell from her mouth as her body rocketed to her orgasm.

Yuzu held Mei in her arms as she recovered, running her fingers through obsidian tresses and murmuring tender words of love and adoration.

When Mei finally turned her head to gaze into Yuzu's face, she said, "I want you to know that this can't become a habit."

Yuzu's heart dropped. "No?"

"On a school night, past midnight? If you intend to…do this, you make your move well before 9pm."

"Got ya." Yuzu laid a tender kiss on Mei's cheek and smiled reassuringly.
