Very Deep

She expanded further with every inch he put inside her, and he now had more than half his tail, at least two and a half feet of the thick limb was filling her stretched-out body. As he continued in amazement, he finally stopped when he had three fourths of it in her. Her belly was extended out, her waist was bulging, and her whole midsection was rounded with the huge intrusion. She was moaning heavily. Her juices, the results of countless orgasms, now soaked more of the sand and trickled down Isaac’s legs.
Still, both of them seemed to want her to be even more filled than she already was. Lysira assured Isaac that she had plenty of stretching left. He grinned and rolled her from being on her back to slightly on her side. He grabbed her tail and guided it to her tailhole. Gently, he pressed it against the tight entrance. Lysira felt an endless ecstasy, pleasure beyond anything she thought possible, and still this new thing, her own tail, penetrating her tailhole right at its base, was so much more than what she already felt. Isaac pressed Lysira tail into her slowly. Very gradually it penetrated her, filling her and stretching her even more than his tail had already. Her whole body expanded as her thick tail slid into her. The feeling of being inside of herself was amazing to Lysira She screamed and groaned with unbelievable pleasure. All the while it was still building as her lover pushed her tail deeper. Now both were amazed to see that Lysira was actually able to take almost her entire tail! Only a small, sharp bend was visible where her tail curved around and into its base. She was penetrating herself, and it was very, very deep. Isaac stroked her expanded belly, rubbing his body against her while his tail still rested inside of her warm depths, and her tail was still crammed into her tailhole. She purred in unison with him as he rubbed her. Her stretched skin was incredibly sensitive, and his touch alone brought her near orgasm. Finally she gave in again and again, the tails filling her, her skin stretched, her lover's touch was, itself, an **** pleasure. She leaked more and more of her sexual juices, and the sand was wet with the liquids of their love. Everything Isaac touched drove her wild, and her juices flowed until she could come no longer. Finally Isaac let his lover relax. He pulled his tail out of her burning hot sex and helped her remove her own from her tailhole, which didn't seem to want to let go of it. They both laughed at this, though Her body quickly went back to its original shape, leaving little evidence of what had happened.
The two lovers embraced, kissing each other deeply, Lysira broke the kiss and looked deeply into Isaac’s eyes and said in that sweet voice of hers. “Isaac do you want to start a family?”
