Looking for specific author/story

[tazellis]

For a long time there was a very highly rated gay sci-fi story on the site. I am trying to get the name or author of the story. It had a lot of chapters and was about an alien race(resembling cats sort of -had tails anyway). The earth guy was taken by the alien race ... Eventually fell in love, had two babies, twins but not identical. And there was a very controversial final chapter with a very strong bdsm feel between the alien and his earth mate and their two best friends. One of the best friends was also human and in a gang back on earth. I hope this is enough info. I am dying to find out what happened to my favorite author and if he ever wrote more episodes. Thanks
