Kurai Shirin Gagged and bound

Episode 1 — Bound in Curiosity
The desk lamp cast its light over the vanity, the shadow of her glasses stretching across the wooden floor. Kurai Shirin sat down calmly, as if preparing a small, familiar experiment. She picked up a roll of silver tape, letting her slender fingers brush against its shiny surface, and smiled with satisfaction.

“This time, I’ll try with more attention to detail…” she murmured to herself. Her soft voice was swallowed by the room as she slowly pulled out a length of tape, cut it to the perfect size, and carefully set the roll aside.

Rin leaned forward, holding the roll in one hand while pulling the tape’s edge to her lips with the other. She positioned it precisely, wrapping it slowly. The sensation of the tape against her skin, and the faint whisper of the adhesive, sent an indescribable shiver through her. She wrapped it until her lips were sealed tightly, her breathing reduced to a soft, muffled rhythm through the layer of tape.

Her usually playful face trembled slightly with excitement, some strands of hair brushing against her cheeks. Once her lips were sealed, the feeling of confinement intensified—like a game in which she was both the creator and the player.

She then began tying herself up. Her hands, accustomed to the rope, moved carefully. She wrapped the rope around her wrists, tightening just enough to be secure but still easily undone. Yet, with Rin’s meticulous nature, she chose knots more intricate than before—knots that initially appeared stylish but could complicate escape when alone.

As she continued, she felt every movement making withdrawal more complex. Her slender hands tried to reach the knots, but the sealed lips and tighter bindings gradually restricted her motions. Her heartbeat thundered beneath her ears, sounding both soft and heavy at the same time.

Rin froze, her face flushed from both embarrassment and a slight guilt, knowing the game might have gone too far. She tried rubbing the knots with her shoulders, seeking a slack point, but every movement only tightened the knots further.

She lay back against the pillow, breathing slowly through the tape. The sounds she made were almost unrecognizable, yet her eyes remained sharp, mischievous, and alert. Rin let out a quiet laugh at the chaos she had created. “Well, that was fun… but next time, I should have an emergency pair of scissors,” she whispered in her mind.

Several hours later

In the silent room, lit only by a dim lamp, Kurai Shirin—Rin—sat motionless on the bed, her body bound by her own handiwork. The white cloth that had initially covered her mouth was now layered with black tape, muting her breaths to soft, quivering sounds.

She tried to move but couldn’t. The ropes were too tight for her to escape, and her sealed lips made her heartbeat quicken, a mix of embarrassment and excitement.

Suddenly, a knock sounded at the door.
“Rin… are you in there?” The clear voice of another girl called out.

Rin’s eyes widened—it was Miyu, her close friend since high school. Before Rin could move, the door opened.

Miyu stepped in and froze at the sight. Rin was tightly bound, pink eyes trembling behind her glasses, her lips taped shut, communicating only her embarrassment through her gaze.

“Rin… what… what are you doing?” Miyu whispered, her face flushed but without judgment—only a mix of surprise and concern.

Rin wiggled slightly, her eyes saying, Help… but remember how embarrassed I am.

Miyu sighed, sitting beside her and gently touching the ropes.
“You’re… way too playful. Do you know how dangerous this is?” Her voice was stern but warm.

As Miyu slowly peeled the tape from Rin’s lips, a soft gasp escaped, followed by a mischievous smile.
“…I just wanted to try it a little.”

Miyu shook her head, her gaze full of tenderness rather than scolding.
“If you want to try… tell me next time. At least I can be there, so nothing like this happens again.”

Rin’s cheeks flamed. She turned her face slightly, but the smile at the corner of her lips couldn’t be hidden. Embarrassment turned into warmth—and perhaps the beginning of a relationship deeper than mere friendship.
