The guards try to use her for sex

The guards had never seen such a beatiful fit girl and will not pass the opportunity to have her body.

Out of the four guards one steps outside to make sure they are not interrupted while he waits for his turn. Of the other three, one lifts her up and another began ripping her clothes. A third cut off the ropes bonding her ankles (they wanted those legs open wide) and took off the bag on her head. A naked girl with her hands tied behing her back could not be a threat to 3 big men.

Katsumi saw that the men were already naked and ready to **** her. They were all tall and muscular. They were well endowed too, specially the balls. The one behind her began squeezing her firm glutes, while kissing her neck while the one in front played with her small but pert tits. Only the one knelt before her while freeing her feet was distracted. She gave this man a knee to the jaw that knock him down on her back. The other 2 men were paralyzed by the surprise but she was as fast as she was cunning.

Katsumi took a small step placing her left foot above his scrotum and stoped hard crushing the first guard's balls into the wooden floor. Having him inmobilized she knock her head back smashing the man behind her in the face and sent a snapping kick to the one in front. So far none of the guards had been able to call for help and she wanted to keep it like that. Three men were already enought to deal with. Her expert kick found it's mark and the third guard got his balls smashed by her perfect right foot. The first man was lost in agony and could only think of the cold foot flattening his manhood. The third one had had his breath knocked out of him and had his mouth open in a silent scream so she focused back on the second, standing behind her. That guard had his hands on his face, trying to contain the blood flowing from his broken nose and never saw Katsumi measuring their distance over her shoulder, much less her butt tensing while her mule kick flew towards him.

She knew exactly how a pair of testicles felt so she checked on the other 2 guards while the heel of her right foot was coming up between his thighs. On his side it felt like a wooden log had crashed into his groin but looking down he caught a glimpse of the pretty sole of her foot disengaging from his nuts and going towards the floor. Devastated he fell to his knees and bent forwards resting his forehead in her back.

Katumi smiled, she had clearly felt one of his testicles rupturing so she knew he was out of the fight.

She had to free her hands before the fourth guard came to check on his mates but 2 men were still not completely out so to gain some time she twisted her left foot. One of his big balls was below the middle of her sole and the other caught beneath her toes. She curled her toes squeezing that ball even harder against the hard wood of the floor and send an open hand strike to the nose of the man in front. The third man had his hands between his legs and caught her blow without defense. The shock of pain in the face made him raise his hands to it. The sexy ninja girl quickly lifted her right leg and while resting her entire weight on the first man's nuts she gave the third one a strong and solid knee between the legs. The first man passed out and the third felt to his knees.

She let herself fall ass first into the first man's groin and took his knife that lay on the floor right where it has fallen when she first knee him.

While she was trying to cut the rope around her wrists the door opened and the fourth guard rushed in.
