Kai drove home from his shift at the local grill restaurant, driving slowly and a little below the speed limit. While most people would be excited, he certainly wasn't. Back at home--he likely had more work waiting for him.
He lived in a modest suburban home, a typical three-bedroom, one-bath setup that always felt a bit too small for his liking. But he didn't have to pay rent, so that was good. At 19, he was stuck between adolescence and adulthood, living under his parents' roof while working a part-time job at the local grill restaurant. His older sister Serena was 21, currently in her final year of college. She still lived at home too, saving money while she finished her nursing degree. They got along well most of the time but bickered here and there, as siblings do.
Their parents were devoutly Eastern Orthodox, strict about their beliefs and moral codes. Church every Sunday, prayers before meals, and absolutely no tolerance for anything they deemed inappropriate. That was the problem.
Kai could never forget the day his parents gave him and Serena 'the talk'. Their parents had just returned from a church retreat, looking more serious than usual. Kai's memory wasn't great in general, but one thing he'd always remember was his father's exact words:
"Masturbation is a sin. It's a temptation of the flesh meant to lead you away from God. Giving in to it weakens your spirit and damages your soul."
Despite the serious talk, Kai and Serena didn't fully buy into the teachings they were raised with. The very next day, when it was just the two of them at school, they voiced their doubts to each other.
"I don't get it," Serena had shrugged. "Why is it bad? Why is just being curious about...that kind of stuff...a sin?"
Kai was relieved to hear her say it. He had been wrestling with the same question too. "I know, right? It's like they're afraid that we'll turn evil if we partake. How can something that doesn't hurt anyone be so bad?"
They'd shared laughs over the contradictions and the loopholes they found in their parents' rigid rules. They were careful, though. Neither of them dared to admit how deep their doubts really went. They still played the part of obedient children, bowing their heads during prayers and attending church without complaint. But the faith their parents tried so hard to instill in them never quite settled in their hearts the way they intended.
Late one night, curiosity got the better of Kai, and he decided to experiment. Locking his bedroom door, he knew the temptation was too strong, and he had to give in.
Guilt followed immediately, and he half-expected his parents to burst into his room to confront him like a SWAT team raiding a house for narcotics. But nothing happened. He didn't feel corrupted or ruined. If anything, he felt normal.
Afterwards, masturbation became a secret habit. He was always careful, locking his door and double-checking that his parents were asleep or out of the house. He never spoke about it, not even to Serena. It was his deepest secret.
Then, a few weeks ago, Kai made a big mistake. Masturbation had become boring, and one day he made his way to the adult store in the mall, purchasing himself a Fleshlight and a bottle of lube. In his haste to hide them before anyone got home, he tossed the receipt in the kitchen trash bin, never imagining anyone would notice.
But Serena did.
She fished it out while cleaning up and confronted him the next day, a wicked grin across her face as she waved the crumpled evidence in his face.
"You know, Mom and Dad would lose it if they found out about this," Serena had teased, folding her arms smugly. "They might even disown you."
Kai's heart sank. He could already imagine his parents' reaction--the yelling, the disappointment, the endless lectures about sin and temptation. There was no way he could let that happen.
Since then, Serena had him wrapped around her finger. He was her personal servant, running errands, doing her chores, and even cleaning up after her. She was already a brat and got everything she wanted, but this took it to the next level. Kai grew resentful, his anger growing each time she ordered him around. He needed leverage, something to hold over her, but Serena was annoyingly careful. Her bedroom door was always locked when she wasn't around or whenever she was in the bathroom. Kai suspected she was hiding something, but he never had a chance to investigate.
Until today.
His shift at the restaurant was cut short when a fire broke out in the kitchen. Luckily nobody was hurt, but they had to close for the day.
When Kai finally pulled into the driveway and stepped inside, he heard the unmistakable sound of the shower running. His parents were out of town on a business trip, so it had to be Serena.
Kai's heart raced when he noticed her bedroom door was open ever so slightly. She must have been in a hurry, thinking she had the house to herself. This was his chance.
His pulse quickened as he slipped inside her room, the air tinged with the faint scent of her perfume. Her space was neat, obsessively organized, but he was determined to find something--anything--he could use against her. At first, there was nothing unusual: textbooks neatly stacked on her shelf, clothes folded in her closet, and her bed perfectly made.
Then he saw it. A pink object on her desk. He did a double-take, his eyes widening as he realized what it was. It was an adult toy, bold and unmistakable, lying out in the open. It was a sleek, pink, U-shaped silicone toy, compact in size with a power button. The remote was small and oval-shaped, matching the toy's pink color. It had a smooth, matte finish with simple buttons and a discreet LED indicator.
Shocked, Kai's lips curled into a grin. He wasn't expecting this. This was his ticket out of being Serena's personal servant.
He couldn't help but grab the remote and press the button to test it out. The toy jolted to life instantly, vibrating intensely and skidding across her desk. He quickly turned it back off and positioned the toy back where it had been, thankful that it was clean. Although they had both agreed that masturbation wasn't as big of a deal as their parents made it to be, Kai never would have imagined that Serena would go so far as to buy a toy to pleasure herself with.
Kai ruffled through her trash can for a receipt, but he found nothing. Then he checked her desk drawer, and tucked away underneath a notebook were two wrinkled receipts. Kai carefully smoothed out the wrinkles from both as he read the details. One was Serena's receipt. The same adult store at the mall, but purchased about a month before Kai bought his stuff. The other receipt was his own--the one that granted Serena the power to use him as her slave. He couldn't believe his luck. Serena's blackmail was officially over. With both receipts in hand, Kai knew the power dynamic had completely shifted.
But then a wicked idea crossed his mind. He looked up the toy online and found out that a remote control could be purchased separately. And conveniently, the adult store in the mall had one in stock. He decided to take it a step further. He popped the battery out of Serena's remote and made sure everything else was exactly as it was before--with the exception of the two receipts, which he pocketed. He knew he had enough time to buy another remote because Serena took notoriously long showers when she had the house to herself.
Kai drove to the mall, speeding, and his adrenaline made the trip feel like a Fast and Furious race. The cashier barely glanced at him as he made his purchase, his heart pounding as he clutched the bag on the way back home. Now, standing in the hallway with his new remote, he heard the hair dryer shut off. He needed to be careful and play his new cards right.
He slipped into his own room, closed the door, and sat on his bed, staring at the remote. His mind raced with possibilities. This was his chance to turn the tables, to make Serena pay for every chore, every errand, and every smug look she had given him while holding that receipt over his head. But he had to be smart. Doing research, he discovered how the remote's sole button worked. It was rather simple. An initial press turned the vibrator on, starting it on level 1, which was the lowest setting. Subsequent presses would increase the level to a maximum of level 10. During any level, pressing and holding the button would turn the device off.
Kai carefully deposited the remote into his pocket, his grin widening. Payback was going to be sweet. But how was he going to get his sister to use the vibrator? And how would he know when she had it in? It wasn't like he could just casually ask her.
Kai stepped into the hallway and approached Serena's bedroom door, knocking loudly and trying to keep his expression casual. He heard her shuffling around before the door cracked open, revealing her damp hair tangled around her shoulders. Her eyes widened in surprise. "Kai? You're home? Already?"
Kai shrugged, leaning against the doorframe. "There was a fire in the kitchen. They sent everyone home early. Nothing big, just some grease flames."
He watched her face closely, enjoying the way she struggled to compose herself. Clearly, she hadn't expected him to be here.
As she opened the door wider, Kai's eyes flicked over to her desk. The pink toy was gone. He fought back a grin. He knew exactly where it was now.
"Oh... well, I'm glad you're okay." Serena hesitated, biting her lip before asking, "Hey, do we have any 2032 batteries at home? You know, those little coin-shaped ones?"
Kai felt a jolt of satisfaction. She was already looking for a replacement, and he knew exactly why. But he kept his expression neutral, tilting his head in curiosity. "What for?"
"Uh...my computer mouse died." Serena's eyes widened just for a second.
"Your computer mouse? You mean the
wired
one?" Kai's grin widened, and he scoffed. He pointed toward her desk, where the black cord of her mouse was clearly visible, tangled behind her laptop.
Serena's cheeks flushed. Her fingers twitched at her sides, the faintest sign of her growing impatience. "Just...do we have any or not?" she snapped, her voice sharp.
Kai shook his head, pretending to think. "Nope, doubt it. Last time I checked the garage, there were only AA and AAA batteries."
Serena's shoulders sagged, her frustration poorly concealed. "Fine. Whatever." She turned on her heel, slamming the door shut behind her.
Kai stood there for a moment, the thrill of victory surging through him. He had never seen her look so flustered. He could almost hear the gears turning in her head as she tried to figure out what went wrong. What she didn't know was that he was many steps ahead.
He turned and walked back to his room, the remote feeling heavier in his pocket. He flopped down on his bed, pulling the small device out again. He leaned back against his pillows, grinning to himself. Serena had no idea what was coming.
Kai decided not to waste his half-day off and sprawled out on the living room couch, feet kicked up on the coffee table, watching the newest episode of his favorite TV series. Serena's bedroom door creaked open moments later, and he fought to keep the smirk off his face as she came into view, dressed in a baggy hoodie and tight black leggings, her hair tied up in a messy bun.
She was heading out. Of course she was. Probably going to get that battery she needed. Kai kept his eyes on the TV but spoke up just as she was about to put on her shoes. "Where are you off to?"
Serena paused. "Grocery shopping," she answered, avoiding his gaze.
"Oh? You sure you're not going to buy batteries for your wired mouse?" Kai couldn't help but take another jab at her.
"Shut up, Kai." Serena's face twisted in annoyance as she bent down to pull on her sneakers, fingers moving quickly as if she couldn't get out of the house fast enough.
Kai watched her for a moment, then lazily stretched his arms over his head. "Hey, before you go, make me some microwave popcorn."
Serena stopped tying her laces and turned to glare at him. "You have legs, don't you? Make it yourself."
