As herself (More gentle mistress route)

Cassandra comes out wearing a plain grey sweater and black tights on a pair of sneakers. She smiles and wrap her arms around Mark for a hug. "Oh, its so nice to meet you!" Mark stays still for a moment, to surprised to move, but then returns the hug gently. "You can hug me harder than that Mark, I workout to." Cassandra pouts cutely.
After a moment they let go and Cassandra beckons Mark to follow her in. As she turns away, Mark check out her tight clad legs. He´d dated a few of the girls at the gym, and Cassandra had muscular legs and glutes just like them. But unlike them she wouldn´t bend over for a spanking.

Cassandra shows him out the massive hall into the kitchen where a man in his thirties is very focused on cooking. He briefly looks up when Cassandra sits down at the large dinner table. "I´ll be done in about 7 minutes."
Mark sits down opposite to Cassandra, feeling out of place in the large hyper-modern kitchen. Cassandra however is totally relaxed, and doesn´t hide that she´s checking him out. "So Mark. If I remember correctly, you don´t have much experience with this sort of relationship? I´m guessing most women who came your way weren´t the bossy type?" "Yes, I don´t have much experience with it. Most of the women I´ve been with wanted a big strong man, which I am, but as their Daddy or stuff like that."

Cassandra smiled. "But you want something different, something Gimpy?" The chef interrupts them with a large plate covered in small slices of bread with varying toppings, all carefully placed. "Wow, great work as always Robert." Cassandra smiles and grabs a salmon and citrus covered sandwich. Mark does the same. The chef leaves them to it and Cassandra continues. "So, let´s get down to it. As advertised, I want you to stay and live here with me 24/7 for a week. Just to see if we could work as a D/S relationship." Mark nodded. "While here you will be my **** or, since you seem to be into it, my gimp. I´m having an outfit readied for you already, it should arrive in a few hours." "Wait what?! How did you get my measurements?" Cassandra gets a mischevious look. "The man who makes my leather gear can model things almost perfectly with eye measurements alone. He will make some adjustments overnight after we try it out today, then it will fit perfectly."

Mark leaned back, processing it. Soon he would have a gimp suit in leather, tailor made for him. It was a lot to take in for a guy who so far had only had leather shorts and hoods in the bedroom. "Wow." Was all he could say. Cassandra continues. "For tonight I won't lock up your cock, I intend to give it at least one good ride before that." Before Mark could respond Cassandras phone rang. "Hello? Yes I'll be right there." and she scurried of to the door. She opened it and a short stocky man in his early sixties came in, followed by an equally short and stocky man who looked to be in his late thirties carrying a large bag.

Cassandra introduced him, and then the younger man pulled out Marks leather suit. Mark was amazed when he got to hold it in his hands. The leather was so smooth, the stitching was so perfect. It had thicker areas at his knees and elbows, and several flaps in case Cassandra wanted to play. Although he was still very nervous about the whole thing, he couldn't wait to try it on. Cassandra ordered the men to leave them alone. "Now then, strip down and put it on. I'll get the back zipper and the hood for you."

When Mark had gotten naked before, most women had been kneeling in front of him, wanting to suck his big cock. But Cassandra seemed to almost grow taller and a bit imposing as he got naked, something about er body language started to radiate power. She was starting to get into Domspace.
Mark slid the leather suit up his legs, enjoying how the leather caressed his ass and creaked as he wriggled his ass into it. It was tight in the back, but that only served to accentuate his butt. He then slid his arms into it, marveling at how well it fit. Last time something fit him so well was when he bought a custom leather jacket, but this was tighter. Cassandra went around his back and started zipping it up the back, all the way up to his neck.

"Now, I want you on your knees Gimp." While she didn't yell, Mark almost felt as is her voice had smacked him across the ass with a riding crop and quickly got down on his knees. She came around with his hood in her hands. She started putting it over his face, smiling as the leather started hugging Markus face as she tightened the cords in the back. "It looks good on you. I'll be sure to show you in just a bit." She took a few steps back "I'm gonna get into something more comfortable, you stay here on your knees until I get back."

Mark stayed on his knees, but let his hands roam his leather clad body. It was definitely a good fit, only a few areas that weren't perfect but he'd still have payed a lot of money for this suit as it was now. He didn't know how long he waited, but suddenly he heard the sound of boots on the floor. He looked to up and saw Cassandra now looking the part of a Mistress. He muscular thighs were covered by tight latex leggings, opening around her crotch. Her lower legs were covered in high heeled black leather boots. Her breasts were held tight by a black latex bustier with red accents. Her arms from her hands up to her upper arms were covered in black latex gloves. Her make-up wasn't to heavy, but definitely gave her a more refined look. In one of her hands she held a large leather collar with blue accents. "I see you're enjoying your outfit." She slipped the collar around Markus neck and buckled it while he admired her. Gently tugging on it, she told him to get up and follow her.

She led him to a large mirror in the hall, Mark see himself. "Woah." Marks whole body was covered in tight black leather, his face was hidden behind his hood, showing only his eyes and mouth. Next to him was Cassandra, looking every bit the Mistress in her outfit and a finger in under his collar. She reached to his cock, gently squeezing the shaft through the leather. "Looks like you're enjoying it Gimp." Mark could only moan, this was a dream come true to him.

Cassandra pulled him to the side "From now on you will refer to me as Mistress C, understand?" "Yes, yes Mistress C" She smiled and guided him to...
