There's a story I read a long time ago, of which I remember many small details but not enough to find it. It was a long story that chronicled a man's first relationship with a dominant female. Overtime, she feminized him, and turned him into a slut to service her friends. She becomes abusive over the course of the story, and by the end of the very last chapter was going to castrate him against his will. However, another Mistress who was friends with the first helped to distract her so he was able to free himself from bondage and the story ended with him becoming her's instead.
There are some other random details I remember. I remember her giving him a blowjob in the first chapter while I believe he was in bondage, the first time that he went to see her. He had a gay roomate, and for some reason a random freudian slip stuck out in my head where he said to his roomate something along the lines of he loves to "service" his mistress, to which his roomate replied that he could smell that on his face.
I think in the second or third session she had him serve, dressed up as a girl at a party and give blowjobs to her friends. I think at one point she had him tied up in such a way that his cock was pointing towards his mouth, and she had him cum in his own face.
If anyone can help me figure out what story this is, I would greatly appreciate it. I've been trying to find it for ages.
