Taboo Sin System

Chapter 9 The First Grope

The timer burned in his vision.

[00:03:12]

Pan had wasted too much time posing and pushing.

"Nah, sis," he said. "I want the satisfaction of taking the cufflinks myself."

Pan let the words come slow, tasting them. "You crossed me without mercy. Dad would have whipped me and put me in the stables for a week. There needs to be a penalty this time."

"What do you mean?" Christina stammered. "What do you mean?" she said again, panic rising in it.

Pan offered her a lopsided grin. "Turn around for me. I want to fish into your back pocket and take the goods with my own fingers. That will be my revenge."

Terror flashed across her face as the meaning of it hit.

Christina's eyes darted again as she took in her position. She was cornered between the island and her brother, with no clean escape left.

"Pan… Please. This is wrong. I am your sister."

"I am adopted, am I not?"

He smirked wider as the lust made him cruel. "You remind me of that every single day. And you are a bully who needs a taste of her own medicine."

Pan leaned in close, low by her ear. "Turn around. I won't ask again."

Christina swallowed hard, her lips trembling. A single tear rolled down her cheek. Defeated, she nodded her submission.

Slowly, the girl pivoted to face the island counter. Her hands gripped the marble edge with white knuckles.

[Christina Submission +3] [Christina Resentment +5]

[Relationship Meter unlocked] [Christina Osborne, 19]

[Affection 0, Lust 0, Submission 3, Fear 0, Resentment 5, Trust 0, Corruption 0]

"Just… be quick," she murmured. "And don't touch anything else. Be careful."

Her voice dropped. "Marta will come through at ten to take supplies for the ballroom. If she walks in and sees whatever you're trying to do..."

That was the first honest thing Christina had said all morning. She was not afraid of him. She was afraid of being seen.

"Don't tell me what to do," Pan growled, reading the new system panel with interest. The Relationship Meter.

It has seven bars, one per feeling, each capped at fifty. The two that had just changed were Submission and Resentment, in the same instant his sister turned around.

The meter would determine how Christina perceived him from now on, and her actions would follow the numbers. She had just surrendered herself to a physical invasion, and the Submission points had shot up for it.

So the panel did not judge, it only kept score. Fear could be raised. So could Submission. Even the last bar, Corruption, sat at zero like a door waiting for a key.

Interesting.

Pan stepped up behind his sister until his crotch nudged the firm curve of her ass through the jeans. She gasped and tried to inch away. He did not give her the space, and dropped his gaze to her lower body.

Fuck, the view is criminal.

The denim hugged every curve of Christina's legs. The seam dug right into her crack like it was trying to split her open.

She had round, firm cheeks that jiggled a little each time she breathed. He could picture the pale, creamy skin underneath, the kind that begged to be spanked red.

Lower down, the fabric stretched tight across her thighs. Everything about her body was disciplined, controlled, and perfect.

Perfect until I decide otherwise.

Pan slid his hand into the back pocket slowly. His fingertips brushed the gold chain. At the same time the heel of his palm pressed full onto one firm cheek of her ass.

Christina flinched hard.

"Pan—!"

"Stay still," he ordered. "I am just retrieving what is mine."

Pan closed his fingers around the chain and pulled it free. He did not lift his hand, though. The challenge wanted ten full seconds.

One. Two. Three.

God, it is plush. The butt's flesh yielded under his grip like warm dough, then pushed back, firm where the running had built her muscle. He spread his hand and took more of it.

Four. Five. Six.

Christina's breath hitched over the stone. She bucked once, her glutes clenching hard around his palm. Pan pinned her with more pressure until she went still.

Under the denim was the edge of lace, the waistband of whatever she wore for church.

Seven. Eight. Nine.

A drop of sweat ran off her jaw and hit the counter. Her knuckles had gone bone white on the stone. She was not fighting anymore, only waiting for it to be over. That was somehow worse, and somehow better.

Struggle, bitch. Make it nasty. You are mine today.

Ten.

Ding.

[CHALLENGE: Your first butt grope] [Completed]

[Reward] [Consumables: Kiss Dart x2, Flash Dart x2]

[Kiss Dart forces the target to kiss the shooter]

[Flash Dart forces the target to expose the area struck]

[The darts are invisible to others, but show if exposed for more than ten seconds. If dropped or lost, anyone can use them. Each dart vanishes after it hits]

Satisfaction hit Pan like a shot of whiskey. He had won.

The cufflinks were in his pocket. The six o'clock timeline was dead. There would be no whipping, no stables, and the evil plan of the two sisters had failed miserably.

Moreover, the challenge's completion gave him rewards. Two darts that forced a kiss. Two that stripped whatever they struck.

Pan went through the rules twice, and a slow grin spread across his face. These were not chore-tools. They were keys, and most of the doors in this world had stayed locked to him for eleven years.

Riding the triumph's high, the victory only made him hungrier. Groping one side, one cheek was not enough. What was he, a middle schooler? Weak.

Pan needed both. The whole handful of Christina's holy ass, to really mark the win.

Something dark boiled over in him.

[Warning: Predator mode active]

Pan's free hand shot out and slammed onto the other side. It rang almost like a slap against his sister's butt. His fingers dug deep, kneading hard, like the flesh owed him money.

"Ow! What are you doing?" Christina yelped and tried to rise off the kitchen island.

Pan held her down with almost no effort, which surprised him. She wasn't resisting much in the first place. "Wait. I am trying to shake the chain loose. It's stuck in the denim."

Christina settled after a moment, panting onto the stone, looking deeply uncomfortable.

"I don't remember pushing the cufflinks in that deep. Be careful. Try not to hurt me."

"Will do, sis. The last thing I want to do is hurt you."

The chain was in his grasp already. Nothing was left to work loose. Both of them perhaps knew it, and neither one said it aloud.

Pan kept both hands on her and kneaded slowly, catching the tremble in her, the change in the way she breathed.

Somewhere in the last half minute her body had stopped bracing to pull away and started doing something else. Her thighs had pressed together. The panting had gone quiet and even.

[Christina Submission +1] [Christina Lust +2]

Pan raised his brows at the numbers.

Is the ice queen getting turned on? My sister likes what I am doing to her?
