This Dragon Forced Me To Breed

Hein - a poor jeweler accidentally awakened Sir Dragon while polishing his newly purchased ring, then realize that his actions were equivalent to praying for fertility, and Sir Dragon forced him to fulfill that prayer. Sir Dragon placed a curse on Hein, transforming him into a woman after ejaculating into his anus.
Poor Hein was penetrated to the deepest part of his body by the dragon's two dicks, exploring the orgasms he never knew and had to endure Sir Dragon's hot semen to produce many eggs.

This was a wild, passionate, and enjoyable lovemaking session for both of them.
