Rina Uchimura is beautiful and tsundere. Men who were rejected by her joined forces out of resentment. They deceived her, expanded her anus with an air pump, and observed it with a speculum. They made her climax with an anal vibrator, relentlessly pounded her with a fucking machine's intense pistoning, and forced her to orgasm with an electric current vibrator! Rina's widened anus swallowed the men's semen.
