You lose. Hard.

You lost the right to keep your name. No doubt about that. Despite this being your first time with a girl, and her telling you that this was her "first time with a guy" (you didn't notice the obvious catch in her words until much later), she had absolutely dominated you throughout the two hour experience. For your name, Sam had picked out the demeaning nickname "Baby Boy", until you managed to negotiate it down to "Boy" with the promise of an hour of facesitting every week. She had wrapped you around her finger faster than you had any idea.

The weeks went by, and you kept up your visits to her house, or sometimes she would visit yours. She kept you to your word about the facesitting, and you didn't even really mind. Sam had been training you well, and by the end of the third week, you had lost track of the amount of times you and her had had sex. It was pretty clear you were girlfriend and boyfriend, and you loved it.

But then, she dropped the bombshell on you. You might have been Sam's first boyfriend... But she had constructed a harem long before you ever knew her. Students, teachers, girls from the night class, and even the principal was a part of it. And this week, her girls were all coming over for a monthly get-together, and you would soon be introduced to them...

And she made it very clear you didn't have a choice.

...You hated how turned on you were by this.
