"Honey, I'm going away with my brother Rob this weekend hunting. He wants to know if you can look after Kate while we're gone."

I raised my eyebrows from my book and looked at him.

"Does your brother trust me enough?" I asked.

Mike laughed. "I guess he does. Oh, and Kate's friend is going to stay with her too, to keep her company."

My pussy twitched slightly at the thoughts of having two 17 year olds with me all weekend.

"You'll be good, won't you?" he asked.

"Oh sure, sure," I said slyly.

Mike cleared his throat. "Um, ok, well... Rob will drop the girls off Friday afternoon when he picks me up."

"Great, I'm sure we'll have a good time," I remarked sarcastically.

Friday couldn't come soon enough as I thought about what would happen that weekend. I was secretive about my intentions to Mike, but I'm sure he knew what I would do once alone with the two teenaged sluts.

I had met Kate a few times. She was haughty little bitch just like most 17 year olds are. But, oh, her body was to be lusted over. She was of medium height, but her legs were impossibly long and slim. Her ass was full and firm as well as her breasts. They were definitely a C cup and I longed to see what her nipples were like. The thought of her writhing naked beneath me, trussed up and bound sent small shockwaves through out my body. I would enjoy breaking her in.

As to her friend, I had no idea who she was. This could make things more interesting as I've never had the pleasure of two slut-girls at the same time. I decided to have a 'friend' help me out.

Alex was a fellow Dom who had been teaching me the art of using rope. I had mostly used restraints such as cuffs and clamps to do my work, but was interested in the intricate procedures of rope. I had seen dozens of pictures on the internet of slaves tied up, but it was harder than it looked.

When I asked Alex to assist me, he was more than willing. He had a special weakness for young girls that I was about to help him fulfill, so it was easy. He would bring all his 'special' equipment on Saturday. I was to have the girls alone on Friday night.

My heartbeat quickened when I heard Rob's car pull up Friday afternoon. I pretended not to be interested as they all entered the house where Mike greeted them. It wasn't until he called out for me that I entered the room.

Kate was standing there smiling and flipping her long red hair at Mike like a little flirt. I narrowed my eyes at her, watching. It was a several seconds before she noticed me.

"Aunt Diana!" she cried and rushed over to me for a hug.

"Um, you don't have to call me Aunt," I said evenly. "It makes me feel old!"

She laughed and pulled away.

"This is my friend Amber," she said, drawing my attention away from her to her friend.

A cute girl with short black hair and large brown eyes stepped forward and extended her hand shyly. I smiled at her and discreetly looked her over. She was a bit small with perky breasts and narrow hips, but when she turned sidewards to give her coat to Mike, I saw she had the most luscious full ass I've ever seen.

"Nice to meet you, Amber," I breathed, trying not to picture that ass ravaged by my mouth.

She smiled sweetly at me and said: "Thanks, same here."

Mike and Rob were anxious to get going, so they hastily took their leave. I gave Mike a big hug and kiss good-bye and whispered to me to make sure I didn't leave any marks. I stifled a laugh and watched them get in the truck and go.

"Ok, girls," I said as I shut the door behind me, "You can use the spare bedroom upstairs to put your things. Unfortunately I only have one queen-sized bed up there, so you'll have to share. Is that alright?"

"Oh sure, Aunt Diana," Kate said brightly. I saw her smile at Amber and they went upstairs with their bags. I sighed and watched Amber's magnificent ass wiggle as she climbed the stairs and willed myself to get through this evening.

I cooked them a big dinner of spaghetti and meatballs which they enjoyed with all the gusto of teenagers. I secretly longed for the time when I could eat that much and still be able to get my pants on. I was only 30, but I had to watch everything.

After dinner, we went into the living room to watch tv. I sat next to Kate and Amber took the recliner off to the side as we watched a movie. I didn't really pay attention to the movie as I was trying to get more comfortable around Kate.

During a commercial I complimented her on her thick red hair.

"Oh thanks, Aunt Diana," she said, flipping it back self-consciously.

"Please, Kate, don't call me Aunt, ok?"

"Oops, sorry."

I reached out and lightly stroked her hair.

"Ooo, very soft too. What do you use on it?"

She told me the names of some very expensive hair care products and I wanted to call her a spoiled bitch. Instead I just smiled back.

I began to comb it with my fingers and she didn't seem to mind. I could smell a fresh scent from it and breathed deeply. I began to wonder what her pussy smelt like once she was all hot and bothered.

Once the movie was over, I began to feel a bit drowsy from the few glasses of wine I had after dinner. The girls also seemed tired and I thought it would be a good idea if we went to bed early. I had told them we were going shopping the next day. Of course that was a lie, Alex would be over to start the fun.

I let the girls get ready for bed first as I was hoping to see them in skimpier clothing. Sure enough, Kate walked around upstairs with nothing but a t-shirt and panties. Her long legs still had a tan from the summer and her toenails were painted dark red. I noticed her breasts poking out the thin material and I thought I could almost see her dark nipples underneath.

"Good night, Diana," she said hugging me again. My body went a little stiff as she pressed those firm, young mounds against me.

"Night, Kate."

I was turning down the comforter of my bed when Amber came in to say good night. She had the same type of nightshirt on and I hugged her as well. When she turned to go, her shirt had ridden up a bit showing me that ass concealed by the white cotton of her panties. I swallowed hard watched her go, shutting the door softly behind her. I so very badly wanted to fuck myself with a big vibrator, but I told myself to wait. It would be worth it.

We were all lounging around the next day after a leisurely breakfast when the doorbell rang. I knew it was Alex and I had purposely steered the girls away from getting dressed into regular clothes. I breathed a sigh of relief as I opened the door.

Alex was big, broad shouldered guy with long dark hair that he usually kept in a pony tail. Today he was sporting a goatee and it made him look absolutely evil and sexy. I had never fucked him, I told Mike that I would never do that as I had plenty of sluts to keep me happy. I'm sure Mike would have let me, but I wanted to keep my relationship with Alex somewhat 'professional'.

He walked in carrying a duffle bag stuffed with probably ropes and other devices and gave me a hug and kiss on the cheek.

"Where's the girls," he whispered.

"In the kitchen, finishing coffee. I thought you'd never get here..."

He grinned at me and took off his coat and followed me into the kitchen.

At this point I had spent a lot of time trying to figure out how to cross the line from Aunt to Dominatrix and realized there was no other way then just surprise. When we walked into the kitchen both girls looked at me then Alex. I saw they were both blushing as they were still in their t-shirts. I had to work fast.

"Girls, this is Alex, a friend of mine. Why don't you go downstairs to the basement and use the shower down there? The one upstairs is leaky. Then we'll go shopping, ok?"

They padded over to the door and I could see Alex watching them intently as their young, hard bodies moved beneath their t-shirts. As soon as the door closed, we waited a few seconds and proceeded to join them in the basement. Everything we needed was down there.

As we descended the stairs, Kate was at the bottom.

"Diana? There isn't a shower in the bathroom down here."

"I know," I said simply as Alex and I made our way down.

She looked confused and a little scared as she looked up at Alex. He was very imposing.

Alex smiled at her and immediately grabbed her around the waist and dragged her to the center of the room and threw her on the carpet. She screamed loudly, but the walls were soundproof and no one would hear us. I snapped on the lights and went over to grab Amber. She was shaking as I pulled her to me.

"Don't worry, we aren't going to hurt you... much." I said softly in her ear. She was trembling with fear as she watched Alex begin to restrain Kate.

He worked fast - in no time he had her hands bound with cuffs and her feet were tied together quickly with a short piece of rope. She squirmed hard, but once restrained, there wasn't a lot she could do. He then put a piece of tape over her mouth and stood up, breathing hard. It was just a preliminary restraint until we had everything under control.

Next I grabbed the other set of cuffs I had laid out and did the same to Amber. She didn't resist as much probably realizing there was no use. Alex was able to bind her ankles and I put the tape over her mouth. I pushed her down on the floor next to Kate and we stood back to admire our quick and dirty work.

"Mmm... Diana, you found two lovely sluts, didn't you?"

"Oh yeah. It will be a great weekend, I can tell."

Both girls squirmed on the floor and there were muffled yells under the tape. It was time for the fun to begin.

Alex unpacked the duffle bag bringing out many ropes and other restraints. He carefully laid out the implements on the floor and started explaining how to use them to me. We decided to do Kate first. Since she had larger breasts then Amber, he was going to show me how to bind them.

We rolled her over on her back so her arms were pinned under her. I used a scissors to cut away her t-shirt and her panties. More muffled yelling was heard, but it only made me more excited. When her breasts and pussy were exposed I sucked in my breath at the sight. She had beautiful luscious tits with large, upturned nipples. Her pussy was neatly trimmed with a patch of red hair.

"Wow," Alex said.

"I know. Did I do good?"

"Fuck yeah," he laughed.

He rolled Kate on her back and began his work. He started with a long white rope and began to loop it around her neck, but not tight, and down between her breasts. Then he wrapped it around her tits tightly, causing them to stick out. Kate moaned and squirmed beneath him until he slapped her face. Tears came to her eyes, but she didn't squirm anymore. Next, he brought the rope down to her pussy where he pulled it through and turned her roughly on her stomach. He then looped another rope tightly around her waist and attached the pussy rope to it. Everything snug and secure and I noticed the rope through her pussy was pressed hard against it. Her hands and wrists were bound with another coil of rope before the cuffs were removed. Finally her ankles were bound for about six inches up her leg. When he was done, he rolled her back so we could see her firm tits sticking out. I wanted to suck them right there and then, but I had to wait.

"God, she looks great," I said as we watched the little slut bound so tightly she couldn't move.

"Yes she does. It will be a pleasure to use her."

We then turned our attention to Amber. Alex wanted to use a less elaborate method on her and he had me do it as he instructed me what to do. First we removed her clothing as we did Kate. She put up hardly any fight, so it was somewhat easy. I rolled her over on her stomach on the cold floor so she would feel it through her pert little breasts. Next I took a single strand of rope and began to bind her wrists over and over (after I removed the cuffs). They were pulled tightly behind her and resting on that ass of hers. Once it was naked, I couldn't take my gaze off it. So full and firm and curvy. I knew I was going to have her first.

Next, I brought her legs up and bent them at the knee where Alex held them for me as I bound her ankles using the same piece of rope that kept her wrists together. It basically forced her to keep her legs at a ninety-degree angle.

Although Alex coached me through it all, it was tough work and I was definitely ready for a break. I went upstairs to change and get some coffee for us.

Lately I had been into wearing the full dominatrix bondage gear. It definitely felt great on my body. I slipped into a latex corset that barely covered my breasts and pushed them up. I then pulled on black, lace panties before putting on my leather mini. For my feet, I had tall, black latex boots with a spike heel. Finally, I slid on black, latex gloves. My pussy throbbed with anticipation as I went downstairs to join Alex.

The bulge in his pants was apparent as I entered the room. He looked me over with approval and smiled.

"You look great," he beamed.

"Thank you." I said, blushing slightly. "Shall we have some coffee?"

"Sure."

We went upstairs leaving our sluts to themselves for a while and planned what we would do with them that afternoon. We decided to do the discipline thing first before any pleasure was to be had by them.

I stood over Kate and handed Alex the whip. Her eyes widened in fear as he raised the horse-hair whip and brought it down on her breasts. A scream was to be heard behind the tape and tears sprang to her eyes. He whipped her again bringing an angry welt on the firm, tanned skin. I realized the slut had been sunbathing nude. Alex grunted and whipped her few more times on her bound tits. They were red but none of the lashes actually did too much damage - they would just be tender for a while.

When Alex was done, he got down on his knees and began to suck her swollen nipples and tits into his mouth savagely. Kate shut her eyes and I wondered if she was actually enjoying it now. Alex continued to suck, drawing her nipple into his mouth and making it hard. He went back and forth for a bit until they were both standing at attention. Satisfied, he flicked them with his fingers until she started screaming again. He stopped and stood up smiling at me.

"She has tasty tits," he said, laughing.

"I bet."

We left her for a while and went over to Amber. I had decided I wanted to spank her ripe, full ass. Alex cut the rope that kept her ankles and wrists so close together and we pulled her up to her feet. I sat down on a chair and Alex brought her over to me and laid her over my lap. Her firm ass beckoned to me and I began to rub it, loving the feel of her hardness underneath my gloves. I then raised my hand and brought it down hard on her ass. A loud SMACK echoed throughout the room.

"Mmmm... ," I heard Alex mutter as he watched a red patch appear on her ass.

I began to hit her again and again. Muffled cries were heard from her as her ass got redder and redder. My hand tingled from the effort, but it was wonderful abusing this beautiful ass. I gave her a few more swats and pushed her off me. She fell onto the floor and looked up with a mixture of fear and lust in her eyes. I smiled wondering just how much she was enjoying it.

Satisfied that both our sluts were properly disciplined it was time for them to start serving us. Alex ripped the tape from Kate's mouth and brought her up to her knees.

She started cursing him out as soon as the tape was off. He slapped her face and told her to shut up, or it would be much worse for her. She gave him a dirty look, but he ignored it as he pulled out his semi hard cock and placed it at her pouty lips.

"Open your mouth, slut and take my cock."

She kept her mouth firmly and defiantly closed. Alex looked at me and I took my whip and twacked her on ass.

"Owwww!" she whined. "Take his cock or you'll get another one."

She reluctantly opened her mouth and he stuffed his cock in. He was a good 8 inches and her mouth soon filled with his hard meat. He grunted and began to slowly slide it in and out of her mouth. I gazed at her bound breasts and saw that they were swollen and puffy from being bound. Her nipples were large and flat now and I wanted to do nothing more than suck them into my mouth, but I had to wait. Alex was having his way with her mouth.
