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.
He began to lunge forward as she pulled back matching her pace and speed. She was letting out soft feminine gasps as he thrust into her mouth. Arthur watched as her hand slid down her neck to one of her breasts as she continued to please him wonderfully. She pinched and played with each nipple letting out louder moans and gasps as she did. Then her hand slid down to her pink patch b/t her legs where two fingers went to work on a virgin cunt.
They thrust in and out and played with a hard clit with obvious practice. She began to lunge on her own fingers as she prepared to orgasm. Arthur to felt one building in his stomach also. He managed to control himself for a while longer. But she was lost in a mindless lust thrusting her fingers, which now shone with fluid lubrication, deeper into her cunt. Finally a loud scream escaped her lips as she came. She fell backwards onto the soft bubble floor and lay there panting before emitting a little squeal and standing beneath him bent in half. Arthur knew what to do after his time with the harpies and the Sorcerers daughter.
He lunged forward in one powerful motion pushing his cock head deep into her cunt. Almost immediately he met with a strange resistance he hadn't experienced in any of his other fucks. So this was the famed maiden head! he exclaimed to himself mentally. He pulled back steadily and lunged in harder breaking through it in one swift movement. The mermaid bit her lower lip in pain but the expression soon disappeared as Arthur pulled back with a low groan.
He began to lunge in and out, in and out at a steady pace enjoying the feeling of her warm cuntal juice and the little blood flowing from her tear. She lifted her feet off the ground as he impaled her again and smoothly turned herself over so her hard nipples and large breasts were pressed against his furry underside. She used his body for leverage and began to grind her wet pussy up and down on his massive cock.
