A group of actresses from Matsushita Koichi's studio subjects a male masochist bound to a torture frame to an extreme tickling session. The M man cries out in intense agony, occasionally locking eyes with Matsushita Koichi himself, who shows up at the studio looking concerned, silently pleading, "Aren't you going to stop yet?" But the tickling punishment shows no sign of ending. The actresses laugh mercilessly, refusing to halt the torment. What was supposed to be a 10-minute tickling session unexpectedly stretches to 45 minutes. The charm of Matsushita's works lies in breaking conventions. For the M man, this excruciating, near-death level of tickling ultimately becomes a cherished memory. For those who wish to experience the ultimate suffering—where you cannot stop the filming by your own will, unlike in a brothel—we highly recommend enrolling in Matsushita's training school to savor the pleasures of hell. The video features a variety of tortures, including intense nipple tickling and tickling while sucking the nipples. The exclusive actresses of Matsushita Koichi's group, who perform this relentless 45-minute tickling assault, are mostly former athletes, their physical builds and endurance enabling such extreme torment. ※ Please note that the same scene is repeated with different camera angles.
