She happily accept anal Fucking

Isaac wanted to try something new. He rubbed a foreclaw against her tailhole, causing her to groan and twitch slightly. He pressed against it and slipped it slightly inside, and she moaned loudly. This surprised him.
"That doesn't hurt at all?" he asked.
"Not at all. I'm surprised you haven't realized how elastic a dragon's skin is. Stretching is not painful, but actually brings us pleasure!" Lysira grinned as she said this.
"Wow... Being a dragon is so spectacular, wonderful!" He exclaimed, then, in a quieter tone he asked, "So... would you like to try anal sex then?"

Lysira nodded, still grinning. Isaac grinned as well, and pulled his finger out of her. He positioned his cock at her tailhole, and gently pushed forward. Slowly his draconic length slid into Lysira tight depths. She moaned softly, but constantly as his shaft pushed into her. Soon all thirteen inches of his dragon cock were buried deep in Lysira’s tailhole, and Isaac rested there, leaning forward to kiss his lover. He did so, and then moved up a bit to her neck. He bit her neck and sucked on her flesh lovingly, Lysira purred loudly, loving the sensations that were pulsing through her body. She felt him deep inside of her tailhole, and it brought her a strange contentment.. Anal sex was different than vaginal, but with that difference, it brought a whole new type of pleasure.
Isaac began to pull out of the tight hole, and then, before exiting completely, pressed back in. Soon he was thrusting in and out, and Lysira screamed with pleasure as he wracked her body with new sensations like nothing she had felt before. Isaac pumped in and out faster and faster, until finally he reached his climax. He pumped her tailhole full of his pure hot dragon seed, and Lysira now felt a filled sensation similar to what Isaac had experienced. His seed oozed out of her anus, mixing in small pools on the sand with the large amount of liquids produced from Lysira numerous orgasms that she had during this new experience.

She took Isaac’s tail and licked it playfully, then stuck it in her mouth and sucked on it with a facial expression of happiness. Isaac purred, and let her do so. He took her tail and sucked on it as well, finding that even this part of her skin had a strange sweetness to it. They went on with this for a while, until Isaac had a new idea.
"Just how elastic is dragon skin, Lysira?" he asked.
"Oh, it's quite stretchable." She replied with a nod.

Lysira wondered what that gleam in her lover's eye was, but she soon realized what his intentions were when he pressed the tip of his tail against her sex. She looked up at him and grinned.
Isaac pressed his tail against her, and soon it was penetrating her vaginal lips. She moaned immediately, feeling the first few inches enter her, each bit wider than the last. He stopped at about the width of his cock, smiled, and then pressed further. They both watched as Lysira’s cunt expanded and stretched with each inch. When Isaac had pushed at least a foot into her, a large bulge in her waist was already noticeable. He looked up for any sign of pain or stress, and saw that she was lost in the pleasure he was giving her. He smiled, and pressed further, wondering just how much a dragoness' body could stretch before she reached her limit.
