Arthur meanwhile was having problems of his own. He had been taken to and locked up in a giant clear bubble that kept the water out but kept him in. He had sat for hours wondering where Dana was and what cruel tortures the lecherous underwater people had devised for her very maidenly body.
Those thoughts had led to others, and his mind was still dwelling on her very very maidenly body. His cock hardened as he remembered the scent of her juices and the feel of her wet virgin cunt on his back as they rode. Then the memory of her giving oral sex to the Sorcerer caused his massive cock to spasm and jump with excitement. A popping sound disturbed his thoughts and he turned to see a young mermaiden lying in the bubble next to him.
She closed her eyes and seemed to concentrate. Immediately her fishy fin began to morph into human legs. Now Arthur had the chance to appraise her. She was totally naked except for a shell necklace hanging between her two large breasts. He noticed that only briefly as his eyes darted to the hard nipples whose pink color was a strong contrast to that of her gorgeous pale skin.
He followed the curve of her waist down to a beautiful pair of sculpted legs that glistened with sweat from their transformation. Tracing her inner thighs upward he noticed she had assumed human female maidenly areas. Once again his cock began to dance in wonder and hope. She teasingly walked around him admiring what hung b/t his back legs. He blushed as he watched her gaze but he saw she seemed to enjoy the sight of him as much as he enjoyed the sight of her.
"Mermaids are a cross breed between fish and man. To survive we must have adequate supply of both breeds in our blood, or we become almost entirely fish and vice versa. We have plenty of fish willing to mate us down here but it is all to seldom we get a man, or even a half breed. If you wish to ever leave then you will fulfill our breeding program and mate 3 young mermaidens like myself. If you do not then you will remain under the sea till you die. What do you choose centaur?"
Arthur didn't even really need to be asked. His cock answered for him as it spasmed again and droplets of precum ran down his head.
"I will take that as a yes. Come and mate me now!" the mermaiden said to him in a voice filled with need. Arthur nearly bowled her over as he galloped to her and she kneeled before him. She lowered her head to his cock and began to run her smooth, soft hands over his length while her small dainty tongue darted and teased his tip.
Arthur lowered his human torso to watch her while she worked. Her tongue caught a droplet of precum as he spasmed again and she giggled. The sound itself was filled with sexual lust. Her hands stroked up and down the length, their years underwater leaving them soft as a down. He lurched forward and let out a long groan unwillingly as she used her long prepared skills to ready him for his coming breeding. She enveloped his cock in her hot mouth, bobbing her pretty head up and down his length.
