Chapter 2 — Forbidden Orbit - Episode 1: The Intruder on Line 2 (2)

Thomas Choi, standing behind Grace Kim, felt his heartbeat pounding so violently in his ears that it nearly drowned out the rumble of the train. He wasn't what people called a "player." An ordinary office worker, he had boarded this unusually packed car today purely by accident. But the moment he saw Grace Kim's pale nape and the gentle curve of her hips barely visible above her slacks, his reason shut down.

At first, it really was an accident. When the train jolted, the back of his hand brushed lightly against her buttock. Thomas Choi flinched, startled, and tried to pull his hand away—but Grace Kim showed no reaction. Instead, she leaned even deeper into her husband standing in front of her.

She's not mad? Does she not even notice?

A strange, suppressed courage surged within him.

Swallowing hard, he slowly reached out again. This time, not a mere brush—but a deliberate, slow glide of his fingers along the curve of her hip.

His fingertips trembled. The terror that getting caught would ruin his life clashed violently with the inexplicable thrill of touching this beautiful woman behind her husband's back. A whirlpool of guilt and desire spun inside him.

Grace Kim felt the tremor against her back. She sensed the hesitation in the man's touch, the fear—he wasn't a professional predator.

This person... he's not a real criminal.

Her tense body relaxed slightly.

She felt a vague sense of relief. He probably wasn't bold enough to pull her away or brandish a knife. Just a pitiful man, chasing a fleeting escape in the chaos of the subway. She told herself this again and again, as if brainwashing her own conscience.

Just endure a little longer. He'll stop soon.

But Grace Kim's assumption was wrong. Her lack of resistance was interpreted by Thomas Choi as silent permission—perhaps even invitation.

His breathing grew ragged. The touch of his fingers was no longer enough.

Carefully, he pressed the hard bulge beneath his zipper against the cleft of Grace Kim's buttocks.

"Mmm..."

Grace Kim unconsciously rubbed her face against David Kim's chest.

Separated only by two thin layers of fabric, the heat and firm pressure of another man's arousal pressed against her. Terrified of being caught, Thomas Choi didn't dare move recklessly—he simply held himself there, fused to her body. Every time the train jolted, the pressure ground against her most private place. Thomas Choi closed his eyes, drunk on the faint, delicate scent rising from Grace Kim's skin.

Slowly, almost as if letting the train's vibrations guide him, he began to rock his pelvis forward and back in soft, rhythmic motions. He wasn't skilled—his movements were awkward, but that very clumsiness made the sensation sharper, more intense. Grace Kim's core grew damp.

Right in front of her, her husband David Kim gently patted her shoulder, checking the station names outside the window.

"Grace Kim, five stops left. Almost there.*"

Each time David Kim's kind voice reached her, Grace Kim's sense of betrayal surged to unbearable heights. Her husband was trying to protect her, while she was surrendering, fully, to the trembling advances of an unknown man behind her.

The fear of being victimized had long since vanished. Now, the raw, unfiltered desire radiating from this awkward stranger was gnawing away at her reason, bite by bite.

Thomas Choi now gripped Grace Kim's waist tightly with both hands. Then, pressing deeper, he thrust himself between her buttocks as if driving himself into her.

Grace Kim bit down on David Kim's tie to stifle a moan. This precarious contact had long surpassed mere groping—it had become a secret, silent dialogue between two strangers.
