Stepsis

He exited the male restroom, but before he could even take a moment to collect his thoughts, a woman—a tremendously busty one, at that—stood directly in front of him.

"Carl?"

Carl stared at her, taking in the sight of a graceful, mature woman possessing a poised and professional demeanor. She radiated quiet confidence and intelligence, clad in an impeccably tailored formal teacher's suit designed to strike a delicate balance between elegance and an authoritative academic vibe.

Her crisp white blouse was strained to its absolute limits, the top buttons desperately fighting for their lives against the massive melons hidden beneath. Below, a tight miniskirt barely reached the middle of her thighs, paired with long black stockings that accentuated her smooth, shapely legs.

Here we go... don't raise, my soldier... don't you dare raise! Carl wanted nothing more than to cover his groin, but he managed to force his body to stay still and composure intact.

Ding!

Unfortunately for him, the Lewd Stepbro System had other plans.

[ SYSTEM QUEST ACTIVATED! ]

[ MISSION: TOUCH AND GROPE THE ASS OF YOUR STEPSISTER. ]

[ DESCRIPTION: YOUR STEPSISTER, WHO WORKS AT THIS EDUCATIONAL INSTITUTION, IS IN DESPERATE NEED OF SOME TEASING. AS A MAN, YOU KNOW EXACTLY WHAT TO DO. ]

[ REWARDS: 1 BRONZE ROULETTE TICKET ]

[ FAILURE PENALTY: 50-50 SPLIT ]

Great... you really pick the absolute best timing, don't you? Carl had no idea what a "50-50 Split" penalty entailed, but he was dead certain he didn't want to find out the hard way.

"Hello there, Teacher..." Carl stammered out, feeling completely out of his depth. He might have been a legendary adult star in his past life, but his formal acting skills had always been notoriously terrible.

"Huh?" Carl's stepsister froze, utterly stunned by the response coming from the boy who had done nothing but hide away in the shadows for months. He had been cold, withdrawn, and completely indifferent ever since the family tragedy struck.

"What happened to you, Carl?! Did someone bully you again? No... tell me, are you hurt right now?!" Her reaction was so sudden and intense that she completely forgot to lower her voice, though thankfully the long hallway was empty.

"No, I am perfectly fine, Teacher. I just slipped and fell," he said, waving his hands defensively as the faint, lingering smell of toilet water on his soaked clothes made him grimace.

"No, this isn't normal at all! Why are you suddenly calling me 'Teacher'?! Did you hit your head or something?!" She immediately grabbed his wrist, dragging him toward her private faculty office down the corridor.

"Wait... please don't pull me, Teacher! Class is already in session, and I desperately need to change my clothes," he protested, feigning reluctance. If he wanted his new approach to work without raising immediate suspicion, he needed to alter his usual pathetic behavior step by step.

"Nonsense! I need to examine your body right now to see if you're injured!" The shock of seeing him act so unnaturally calm was driving her mind wild with concern.

The old Carl would have cowered, sprinted away, or accepted his miserable condition as normal. He usually didn't give a damn about getting bullied, nor did he ever speak up for himself. Yet now, he stood before her looking completely different—addressing her as "Teacher" instead of his stepsister, his eyes looking straight into her face rather than blatantly ogling her chest and rear like he usually did.

Creak... Bang!

She pulled him into the empty room and shut the door behind them.

"Teacher, please let me go now. My spare uniform is kept inside my locker," Carl said, gently pulling his hand free from her grip. He had a singular objective today: avoid acting like a pathetic simp on his very first day of transmigration.

"What on earth happened to you today, Carl?!" She spun around to face him, her frantic movements causing her lush breasts to jiggle violently beneath her blouse, coming within a hair's breadth of spilling out right in front of his nose.

Look, I love huge tits as much as the next guy, but definitely not right now. I am not risking finding out what a 50-50 Split penalty means, Carl thought, keeping his focus locked strictly on completing his mission.

"Nothing happened, Teacher. My clothes just got soaked, that's all."

"No, I know something happened! You're acting completely out of character... and why do you keep calling me 'Teacher' instead of my name?" She shifted nervously from foot to foot, utterly unaccustomed to hearing a clear, articulate tone from a boy who usually pretended to be mute around her.

"You're overthinking things, Teacher," Carl replied softly, taking a deliberate step closer to her. He needed to grope her ass to fulfill the quest, and he just needed the perfect opening to strike.

System, give me the probability of successfully touching her ass right now.

[ CALCULATING... 14 MILLION POSSIBLE OUTCOMES, HOST. ]

Great, you're not helping me at all. Give me the actual percentage instead!

[ 78% CHANCE OF SUCCESSFUL PHYSICAL CONTACT WITH TARGET. CURRENT AFFECTION RATING: 5% TOWARD HOST. ]

Man, what a classic stepbro setup... Was this original kid really so pathetic that he had to sneak into his stepsister's bedroom just to steal her panties? The only reason he hasn't been branded an open pervert yet is because of his stealthy moves, Carl thought while carefully calculating his distance.

"Is that so? Then let me see for myself!" Silvia declared without hesitation, stepping forward to yank his wet shirt upward.

"Don't touch me, Teacher! I can handle it myself!" Carl protested, skillfully sliding his hands around behind her waist, hovering mere inches away from her firm, rounded buttocks.

"Don't fight me on this! I'll call Mother right now if you try to hide injuries from me again," she threatened, resorting to her ultimate leverage.

"You can't do that! I didn't do anything wrong!"

"You certainly are! I know for a fact you're hiding something... why are you acting so distant and strange?!" Taking the initiative, she dragged his frail frame toward the teacher's desk in the center of the room.

"Stop it, Teacher!"

Unfortunately, despite his inner determination, Carl couldn't physically overpower her. His current body was terribly weak and frail—a direct result of being severely malnourished from his ridiculous habit of masturbating five to seven times a day, every single day!

"What is all this...?" Silvia gasped, freezing in place as she pulled his shirt all the way up.

Exposed across his pale torso were clear, angry bruises—fresh, dark purple punch marks scattered across his ribcage and stomach.

"Don't stare at it, Teacher..." Carl muttered, his voice dropping low as her eyes filled with shock and distress.
