This is my first time writing a story like this, feedback and constructive criticism are appreciated! I plan on writing a few more parts to this that focus on chastity and what happens after the end of this story.

I've been president of the chess club at my college for the past 2 years. I was simply better than everyone else, so when it came time for voting, I was elected with no real competition. I was cleaning up after another successful meeting when a girl walked into the room. She was a shortstack, only about 4'11" with a beautiful face, ass, and set of tits. She came up to me, introducing herself as Jennifer and telling me she had an interest in joining my club. After the first few weeks of the semester I didn't usually allow new members, but I figured I'd be able to make an exception for someone like her. I was about to let her know she had a spot when I decided to flirt around a bit with her first.
"You're in the club - on one condition" I said. "You play me in a game of chess where the loser does one task of the winner's choice." Once I won, I'd ask if she'd like her task to be going on a date with me.
"Omigosh, yes!" She giggled with a sly grin on her face. "I even brought my own set we can use!" As she pulled it out, I was impressed at the quality I saw. Each piece was made of carved wood and each king had a diamond on top of its crown. After I won a coin toss to determine who would play as white, Jennifer set the board up. When I looked down to make my opening move, I noticed how the diamond on Jennifer's king caught the light coming in from the window. I found myself just staring at the glimmer as a sort of fuzziness was clouding my mind. Suddenly, as the fog fully enveloped my thoughts, a sharp voice cut through directly into my mind.
"Having trouble thinking? Try playing F3!" Jennifer's voice said, immediately being replaced by white noise again after. F3? I felt like something was a bit off - but the fuzziness stopped me from thinking about that further. My hand moved and pushed my pawn to F3, but my eyes never left the diamond.
"Hey, it's your turn again - maybe you should play G4?" Again, Jennifer's voice went directly through the fog into my brain. I hadn't even realized she'd made her next move. The little nagging feeling was still there, but weaker than last time. It quickly was overwhelmed by the fog, and I was happy to move my pawn up to G4.
"Aaaaand checkmate!" Jennifer squealed excitedly. I managed to drag my view away from the diamond for a moment - she had put me in fool's mate! My mind was racing, trying to figure out what had just happened when I heard her joyous voice say "For your task, I want you to look me in the eyes!" My eyes shot up to meet hers as I immediately saw her holding the ornate diamond between her deep hazel eyes. I felt the fog reenter my mind far stronger than it had before as one word hit my mind like a ton of bricks.
"Sleep." I instantly lost consciousness.

Groggily, I opened my eyes. "Wh... What happened?" I whispered. As my vision focused, I saw Jennif- no, Mistress Jennifer still sitting across from me. I tried to ask her what she had done, and why I was only able to think of her as Mistress Jennifer, but I couldn't move my mouth. Mistress Jennifer noticed me struggling.
