Chya walked into the kitchen and stopped in the doorway.

Marco was finishing drying the dishes, his back a little hunched from tiredness.

She watched him in silence for a few seconds, her blonde curls falling over her shoulders, her perfect breasts faintly outlined under the light t-shirt.

“Still you doing the chores,”

she said with a half-smile.

“Last night I saw you on the floor in the living room. You looked almost like a sack of potatoes.”

Marco turned sharply, his cheeks already a little red.

“It was nothing.

I just dropped the controller and fell.”

Chya tilted her head slightly, amused.

“Really?

Because from the way you were holding your groin it didn’t look like a simple fall.”

He lowered his gaze and went back to drying a plate with too much attention.

“I’m telling you nothing particular happened.”

Chya stepped closer and leaned against the table, arms crossed under her breasts.

“Fine.

Keep lying.

I already know how things went.”

She stayed quiet for a moment, then added:

“Listen…

I’ve got a lot of stuff to do today and I don’t feel like it.

How about you do my chores?”

Marco looked up, a bit suspicious.

“In exchange for what?”

Chya smiled slowly.

“In exchange for a blowjob.

Here, now, in my room.

You do all my chores for three days and I give you a blowjob.”

Marco stood still.

His heart sped up, but he immediately shook his head.

“No.

I’m… not interested.”

Chya raised an eyebrow, still smiling.

“As you wish.

If you change your mind you know where to find me.”

She pushed off the table and left the kitchen without another word.

Half an hour later Marco knocked on Chya’s bedroom door.

Her voice came from inside, calm.

“Come in.”

He entered and closed the door behind him.

Chya was sitting on the bed, blonde curls loose, her perfect breasts faintly visible under the t-shirt.

Marco stood there, hands slightly clenched into fists.

“I… I changed my mind.

I accept.

The blowjob.”

Chya looked at him for a long second, then a malicious smile appeared on her lips.

“Really?

Then come here.”

She stood up and positioned herself in front of him.

Marco was already looking at her with slightly wide eyes.

His cock was pressing hard against his pants, clearly visible.

Chya lowered her gaze and smiled.

“Look at that…

already all ready.

Pull down your pants.

Get undressed.”

Marco obeyed immediately.

He slid off his pants and boxers in a few seconds, left naked from the waist down, his cock already hard and throbbing.

Chya watched him with a malicious look, without touching him.

Then, without warning, she raised her knee and slammed it hard right into the center of his balls.

The impact was sharp, full, cruel.

Marco let out a strangled sound.

His legs gave out instantly.

He dropped to his knees, then collapsed onto his side, both hands clamped over his groin, body curled in on itself as the pain exploded in hot, nauseating waves.

Chya stayed standing, her knee still raised and held right in front of his face, as if she were still aiming.

She looked down at him, voice calm and amused.

“So?

Do you still want the blowjob?”

Marco shook his head with difficulty, eyes closed from the pain, voice broken.

“N-no…

no…”

Chya slowly lowered her knee and smiled.

“As you wish.

But you’re still doing my chores.”

She turned and went to open the door.

“Now you can get dressed and get out of my room.

Thanks.”

Marco and Lily were on the living room couch, controllers in hand, locked into a fighting game on the PlayStation. They were both almost twenty, but she was still “the little sister” in the house, especially when it came to competing.

“You’re losing pretty bad, Lil,”

Marco said with a smirk, eyes still on the screen.

Lily clenched her teeth. She only had a sliver of health left and he was about to close out the round. Without warning her right hand left the controller and shot straight between her brother’s legs. Her fingers closed around Marco’s balls through the thin shorts and squeezed firmly.

“Ah—!”

Marco jerked forward, the controller slipped from his hands, and in less than two seconds his character was on the floor. Victory screen for Lily.

She let go almost immediately, but not before the pain had already hit. She turned toward him with a bright, wicked smile.

“Oops. Hand slipped.”

Marco was bent forward, one hand already protecting his groin, breathing hard.

“You’re… you’re a bitch.”

Lily rose onto her knees on the couch, still smiling.

“A bitch? I just won. You’re the one with balls so sensitive that a single grab makes you lose all concentration. They’re literally your weak spot, aren’t they?”

“Shut up…”

“No, come on, admit it.”

She leaned a little closer, voice lower and amused.

“They felt so full and soft. It felt really good holding them for a second. Almost a shame I had to let go so soon.”

Marco looked at her with a mix of anger and something more confused. The pain was still throbbing, hot and unpleasant, yet her words stuck to him longer than they should have.

“Now you get to do the chores,”

she sang, standing up.

“As agreed. Have fun washing the dishes while I enjoy the win.”

Two hours later, after finishing the kitchen, Marco came back into the living room with the face of someone who hadn’t swallowed the defeat.

“Rematch.”

Lily, sitting cross-legged on the couch scrolling her phone, raised an eyebrow.

“Oh? You want to lose again?”

“This time the stakes are higher. If I win, you do the chores for both of us for three days. If I lose…”

he hesitated for a second,

“…you get to kick me in the balls and I still do the chores.”

Lily stared at him for a moment, then a slow smile spread across her lips.

“Interesting. So you’re willing to risk those poor balls of yours again just to try and make me work. Brave… or stupid.”

“Do you accept or not?”

“I accept. But one rule: no touching the balls during the match. No low blows while we’re playing.”

Lily raised her hands in surrender, still smiling.

“Fine. No hands on the balls during the match. Promise.”

They sat back down. The match started again, more tense than the first. Marco played focused, almost aggressive. Lily, on the other hand, looked almost relaxed, like she already knew how it would end.

They reached the deciding round. Marco was winning. Lily had almost no health left. Then, instead of reaching for him, she did something completely different.

She set the controller on her thighs, grabbed the hem of her shirt, and pulled it off in one smooth motion. She wasn’t wearing a bra underneath. Her breasts bounced lightly once free, bare and only inches from her brother.

Marco froze for a fraction of a second too long. His eyes dropped on their own, his brain short-circuiting.

“Lily, what the fu—”

He didn’t finish the sentence. His character was defeated. Victory screen for Lily.

She calmly set the controller down, still topless, and looked down at him.

“Stand up.”

Marco stared at her, still dazed.

“What…?”

“Stand up, Marco. Now.”

Her voice was soft, but it left no room for argument.

“Open your legs. Wide.”

He hesitated a second too long. Lily tilted her head slightly, her bare breasts shifting with the movement.

“Don’t make me repeat myself. You lost. You earned the kick, and I want to give it to you properly.”

Marco slowly stood up, cheeks already hot. He spread his legs as ordered, standing there in the middle of the living room, exposed and waiting.

Lily stood up as well, stepped closer, and looked him straight in the eyes as she raised her knee.

“Look forward. I want you to feel all of it.”

The kick came sharp, precise, and full. The top of her foot slammed dead center into Marco’s balls with cruel force.

A strangled sound tore from his throat. His legs gave out instantly. He dropped to his knees, then collapsed onto his side, both hands clamped over his groin, body curled in on itself as the pain exploded in hot, nauseating waves.

Lily stayed standing over him, still bare-chested, watching him writhe with a satisfied smile.

“There we go. Just like that.”

She leaned down a little, voice low and amused.

“You opened them up so nicely for me… they were right there waiting. Full, soft, and now on fire. You felt that impact, didn’t you? That dull thud… I liked it.”

Marco couldn’t answer. He was breathing in short gasps, eyes closed, face tight with pain.

Lily straightened up, picked up her shirt without putting it back on, and gave his shoulder a light nudge with her foot.

“Come on, get up when you can. The chores are waiting. And while you’re doing them, remember your balls are still burning because your sister made you spread your legs and wrecked them with one single kick.”

She walked toward the living room doorway, then stopped on the threshold and looked back one last time, laughing under her breath.

“They really are nice balls, Marco. Shame they’re also so easy to put out of commission. Have fun washing the dishes with those things on fire.”

And she left, leaving him still on the floor, legs trembling, the pain showing no sign of fading.
