"Agreed." They circled each other like a pair of alleycats. Kurt struck first. Kitty blocked his kicks and fist strikes. She had the advantage of being already warmed up. After a few solid minutes of dancing around each other, Kurt lunged forward and caught her around the waist, bringing her down to the mat. She was not a very good wrestler due to her smaller size, but she'd always been an expert on wiggling. She squirmed out of his grasp and swung her fist into his solar plexis. He gasped and backed away. She rolled back onto her bruised shoulder and sprang to her feet. She spun on her toe, but Kurt managed to deflect her foot and snake his tail around the ankle that supported her weight.
Kitty went down on the floor again and lunged away from her opponent's well-aimed kick. The blow glanced off her good shoulder and she bit back a cry of pain. She flung herself under the remaining punching bags and stood between them, sending one swinging toward Kurt. He angled his body away from it and missed his chance to grab her. She continued to fight, but she was tiring.
Kitty executed a rather tidy back handspring and he had to duck fast to avoid her flying feet. He slipped under her next flip and seized her wrist with his tail. She managed to land on her feet, but he got one of his hands on her ankle and with him pulling from top and bottom, she tumbled to the floor again. He wrapped an arm around her neck and pinned one arm behind her back while holding the other with his tail.
Kurt was using one of Scott's wrestling moves to subdue her, but he must not have done something quite right because her sharp little teeth clamped down on his wrist. He grunted with pain when he felt the skin break under her desperate assault. With a snarl, he ripped the collar of her shirt and sank his fangs into her battered shoulder. Kitty let out a cry and seemed to explode within his arms. She knocked him backwards and flipped over, landing on his chest. She grabbed the sides of his face and lifted his head, slamming it back on the matted floor. She jumped up and started to run away but he grabbed her around the knees and she landed with a squeak on her stomach. He crawled up her struggling form and used his weight to pin her down. Blood soaked through her shirt where he'd bitten her but she paid the injury no mind. She jerked her head back and tried to hit him in the face with her skull. When he ducked and held her firmly to the floor she took an unexpected approach.
Kitty knew she was losing the fight but with Kurt's tail in the mix, she told herself it wasn't fair to begin with. She arched her back and pressed her buttocks firmly against his pelvis. For a moment he stopped breathing. He still held her limbs immobile, but she wasn't without resources.
"Tricky, Liebchen." Kurt growled into her ear. "But I'm in the mood to call your bluff." He was feeling savage, and the smell of a warm female beneath him was more than he could combat when his blood was up.
