His opponent was ready, ducking to the side and trying to trip him but Ao had fought before, he jumped spinning and kicking. A blow connected solidly in the man's chest, another connected with his throat. Ao went down on top of him, trying to pin him. The man struggled, slamming an elbow repeatedly against Ao's face, he felt blood splatter and tasted the iron. He loosened his grip, the man rolled and Ao found himself on the bottom. It was blindingly fast. First he had been slamming his fists down and now it was all he could do to get his arms up in front of his face.
Bad move. His opponent reached down and grabbed him by the balls. It was a feeling as if he was held - he lived or died in this man's hands. He felt all his power, all his dominance, all his will to take and destroy this man - fade away. The man slammed his fist into Ao's jaw a few more times for good measure and then grabbed his hair as he stood up. Ao tried to struggle but found his body to be oddly weak. He shouted but it came out as more of a girly shriek. Ao wondered why the man had let go of his balls.
The crowd roared, and the man went down to his knees behind Kneeling Ao. A Knee came between legs, which Ao instinctively parted. Ao felt the man's cock pushing and moaned involuntarily, suddenly wanting it inside of her. She felt wet at his dominance of her. She arched her back as the man grabbed her hips and slammed himself into her newly formed slit.
She gave a gasp as it felt like the air was knocked out of her. He was huge and she had never been entered. It took a moment to get her breath back, and move through the pain of this massive thing in unexplored space, but once she began to breathe she noticed how much she had changed.
Where Ao had taken pleasure in dominating suddenly she found it in being dominated. It was so easy now. How had she thought this a bad thing? The man pumped in and out of her and she felt awash in new sensations. More pleasure than she had ever felt before.
He grabbed her hair and she reveled in it as he pulled her up and closer, turning her and kissing her, his lips claiming her as his own. His hands pawed at her breasts, bringing up a new flurry of sensations, and still inside of her was that pounding, a constant rhythm, a beat to the melody of her pleasure.
Then he picked her up, and still inside her spun her around. Holding her easily in his massive arms, he showed her off to the world. The crowd roared and hooted as she hung there embedded on his massive cock. He brought her up, and let her go holding her for a moment with the strength of his cock alone before returning hands under her.
She was his. He claimed her, took her, owned her. There, held in his big strong arms he bellowed and emptied his overfull balls inside of her. She could feel it. She had always wondered if a woman could feel it - it felt riverlike, and at its crashing she exploded, her eyes closed and her world filled with stars.
Then she was being carried over the man's shoulders out of the pit. Behind her two women entered and the crowd roared. The man, already erect again, bent her over the bench and entered her again. She was still wet and slippery from his last load and it slipped in easily. She knew that a newly made woman was almost guaranteed to get pregnant from this, and she found that excited her. She wanted a baby. She wanted a baby from this man. His second ejaculation triggered her second orgasm. Her pleasure came from his.
He dressed but left her naked, paying the pit, and stepping out with her into the streets. Ao looked up at the clouds racing above her, the crowds cheered behind her - then she looked back up to meet the eyes of her master. Ao smiled.
