Ayako grabs him by accident

Ayako suddenly faltered. Her foot slipped on the rope, and on instinct, her hand shot out to grab something—anything—for support.

Unfortunately for Shirou, that “something” was his pants.

“Ayako, wait—!” Shirou yelped, feeling the sudden tug.

But Ayako, not realizing her mistake, clung tighter. With a sickening fwoop, his pants slid down. Shirou froze, his mind struggling to process the situation. His belt, already loose, gave way without a fight. Worse yet, Ayako’s death grip yanked down his underwear along with it.

Time seemed to slow.

Ayako blinked. “Uh—Shirou, I—”

“Let go, Ayako!” Shirou yelled. He tried to reach down to pull his pants back up, but the effort only caused him to wobble dangerously on the rope.

“I can’t!” Ayako shouted, still struggling to regain her balance. “If I let go, I’ll fall!”

And then it happened.

With a final tug from Ayako’s flailing hand, Shirou’s pants and underwear dropped all the way to his ankles, leaving him dangling there with nothing but his shirt and his whole tiny flaccid cock.
