The popular training series returns! This time, company secretary Murakami Ryouko, a clumsy airhead, has been blackmailed and transformed into a shameless nymphomaniac who can't get enough of vibrator insertions. Called in as usual, she reluctantly submits to public masturbation and humiliating sex, trembling as her body heats up with arousal. Enduring relentless vibrator and electric stimulator torture, she repeatedly squirts in spectacular fashion—must-see scenes. In the end, she collapses onto all fours, becoming a ravenous sowslut greedily devouring cock.
