Jeff quickly came to her senses calling back to Emma, "But Mistress, I thought I'd be the knight."
"A Peasant like you? A knight? Don't be ridiculous slave." Emma laughed condescendingly, getting into character.
Jeff, forced into staying in character just looked to the ground, unable to say anything more. The Jeff fought against them, but a tear still escaped.
Emma, not truly a heartless knight with a slave, realized something about this was truly upsetting Jeff, and it clicked. "Aww, Jeff, you suggested this because you wanted to be a big, strong, powerful man, didn't you?" Jeff nodded. "I thought you'd find this fun and I didn't mean to upset you... If you are REALLY THAT attached to your gender" She gave a final glance to Jeff who was nodding vigorously. "I have a few other ideas, give me a minute, I can change things around."
Jeff ran to the bathroom already feeling his breasts deflate and his stature increase. Emma was typing furiously as the physical changes she queued went into effect. A few seconds later she had finished with the second set of instructions and set it into motion.
She stood to greet Jeff in the bathroom finding him admiring his enhanced form. "You made me more masculine!"
Emma smiled at her handy work, "I did. I didn't realize you identified so strongly with your masculinity, I wasn't trying to hurt you and I thought it would be a fun change of pace. I won't make you female without your permission again. However... You did diminish my fun, just a tad... I was looking forward to watching you get hit on by guys, and watching you squirm... so, to make up for it I made you illiterate like a real slave would be, and you're becoming a little dumber by the minute my big muscley himbo, and you're still my slave... if its a good enough role for me to play, its a good enough role for you to play..." she shot a glare.
"Yeah babe, that's cool for a night, I just didn't want to be a girl and it wasn't good for my mental state to have my identity ripped away from me." Jeff said, but it came out as, "Yes mistress, I am further indebted to you for your charity. I suffer not for the additional payment you ask but truly could not bear your original plan."
The couple shared a confused glance but after a few eye signals and head nods the meaning was confirmed. Jeff turned back to the mirror admiring his build having shifted toward athletic, and the day or two of stubble having appeared, fully that he had yet been able to grow. Emma confirmed he was now 18, and had a build matching what his role would be serving her estate, acting as builder, carpenter, gardener, cook, stable master, and any other role she was shorthanded finding help with...
Jeff and Emma got into the car, Emma drove, and Jeff didn't realize he usually insisted on doing the driving, but it felt natural to follow his owner's lead. Driving through town Jeff realized all the stores, he recognized by color and visual makeup but couldn't read the signs. Maybe letting her make him illiterate was a bad idea...
They arrived at the party, and by that time Jeff could recognize people as friends but most of the thoughts going through his head were of the chores he still had to do tonight and tomorrow to keep Mistress pleased with him, and remain her most highly prized slave. Its truly an honor, it is.
