Rabbit-like beauty Kurumi Amai strikes back at a male masochist in a sleek black string bikini. Kurumi's tight-fitting black bikini perfectly accentuates her gorgeous figure, captivating the viewer instantly. The restrained M man has his arms and legs completely immobilized, unable to move at all. Then, Kurumi begins her "counterattack tickling" in full force. First, she uses her fingers to tickle the soles of his left foot while telling the man about her hardships, saying, "This was really tough, you know." The man bursts into uncontrollable laughter, unable to hold any conversation. Next, Kurumi moves from his calves up to his inner thighs, all the while turning her backside toward the camera, adding a highly erotic vibe. She then shifts to tickling the sole of his right foot, teasing him with, "They told me it's extra ticklish when you tense up~." The man can't stop laughing, completely overwhelmed, his face showing nothing but helpless giggles. Gradually, Kurumi's sadistic side starts to emerge. She positions herself between the man's spread legs and demonstrates her skill by tickling both feet simultaneously. As she moves from his inner thighs to his side ribs, she repeatedly questions him, but he can barely respond, lost in endless laughter. Then, moving behind the man who's now bound with arms raised overhead, she attacks his back, armpits, and upper arms. Putting on gloves and applying cream, she says, "Let's make this extra slippery~," before zeroing in on his armpits. Her intense, gritty tickling technique amplifies his reactions, making his laughter grow louder. She follows up with a devastating combination of underarm and side-tickling, driving his responses to new heights. Finally, she runs her hands all over his body, checking his reactions thoroughly, showcasing her sadistic tickling mastery and Kurumi's dominant charm. This title perfectly blends the fun of tickling with a strong S-girl atmosphere—highly recommended! Don't miss it!
