Doll Collar

"Master said to play with tits not his cock," she murmured dreamily. "My nipples are so damn sensitive today. I could almost cum from just playing with them. Do you want me to cum for you Master?"

"No," I said and she smiled again. "I want you to suck me off."

"Can I swallow Master?" Haley asked in that sultry voice and I nodded. "MMMMM, Master is very kind."

I watched as she dropped down to her knees and using just her mouth snared me between her lips. She focused on the tip for now and I couldn't fight the urge to moan. When I was painfully hard she began using her hands. She lifted my cock up so that she could lick the underside as well as suckle my balls. Haley was going all out. She swirled her tongue around the sensitive head before thrusting her head forward and deep throating me in one go. I grabbed her hair instinctively and that ratcheted up the intensity a few notches. She took my other hand and placed it at the back of her head. The meaning was clear.

"You want me to fuck your face don't you," I asked and she moaned around my dick in answer.

I pulled her head forward driving my cock as deep as it could go. She would pull her head backward and we'd repeat that until I was shaking so bad I was seconds away. I told her I was close and she took over and began ramming her head forward and licking and sucking for all she was worth. I cried out as my load hit the back of her throat. Sis gobbled it up and I stood there shaking. I remembered the machine and saw that I had mere seconds left on the timer before the collar shut itself off.

"Forget and sit back down," I cried out as sis licked the last of the cum from my cock.

"That was tasty," she said as she returned to her seat. "Why am I naked? Why is your cock out?" She asked as she licked her lips. "Oh someone's been a naughty boy."

I tucked my cock in and zipped up. I asked her how she felt and sis just smiled. That's when she dropped the bombshell.

"You don't have to make me forget," she purred. "I like sucking dick especially yours."

I glanced at the monitor and she was still under the influence. I almost told her to forget again but I found myself too curious to stop myself.

"Remember," I said. "Remember this last session only."

"You ordered me to suck your cock," sis said blushing. "I knew you had it in you, Master."

"That doesn't bother you?" I asked and she shook her head. "Any suggestions," I asked and she nodded.

"I will show you once I get unhooked," she replied cryptically.

We sat out the remaining six minutes and Haley never even bothered putting her dress back on. She caught me staring at her tits on more than one occasion. She just smiled and winked. Once her pattern had returned to normal I interviewed her on how her experience had been and she had nothing detrimental to say. That surprised me quite a bit. When I asked her about being ordered about she replied that many women like a firm hand from their partner. Is that what we were then, partners?

I removed the headgear first but when I reached for the collar she shook her head. I unhooked the charging cable so she could walk around in it. Haley raced upstairs and returned with one of my tablet computers. She plopped down in my lap and held it up so that we could both see. I could feel the way she ground her ass against me as she opened up the files she had been working on. They were collar designs. Sis told me that my design while functional looked like shit. No gal worth her salt would be caught dead wearing my collar. Her sketches were impressive and she was eager to help me on finding attractive young ladies to model for me.

"Wait a second," I said as her hips did slow circles over my groin. "Are you saying you want to help me get laid?"

"I want you to realize what a good thing you've got going on here. There are some seriously sex starved MILF's out there that are too shy to go out and get a good cock. You have an amazing cock once we get it trained."

"What the hell does that mean?" I asked and sis just giggled.

"You are a near virgin, we need to fix that. Once we are over that hurdle we can address your skills as a lover. I can handle everything."

"Whoa, wait a second, you want to be my sexual instructor?"

"That is one way of putting it," she said. "I prefer the term fuck buddy. No emotional strings attached just good old fashioned sex. What do you say?"

I never had the chance to answer. Sis lifted up long enough to unzip me and free my cock. She took me in hand and before I knew what was even happening impaled herself. The little shit had taken off her panties when she went upstairs. I was now balls deep in her soaked cunt.

"Oh god, you are bigger and thicker than I remember," she moaned. "This is gonna be good! Now let me do all the work for now."

I was too stunned to say a word. She leaned forward and set the tablet on the work surface. Haley began lifting up nice and slow and then falling backwards driving half my cock deep into her. She repeated this several times before switching gears. She used her hips and made those slow circles again driving us both crazy. I cupped her tits and weighed them in my hands. How the hell did I go so long without this? I teased her nipples on her suggestion and found the perfect amount of pressure for her liking. Oh god, was I actually analyzing tactile pressure as I had sex? Yes I was, I was hopeless. Suddenly everything stopped and I looked up to a very unhappy Haley.

"I can see it in your eyes. You are doing the math while I am fucking you, aren't you?" She asked and I nodded. "I have just the solution."

She removed the collar from around her neck and placed it on me. She adjusted it so that it fit comfortably. She dragged the laptop over without disengaging us. With a few mouse clicks the very first setting was up and running. It felt like she was stroking my cock without ever moving. There was a kind of tunnel vision and then Haley was on her knees on the floor and I was behind her fucking her like crazy. I was slamming my hips into her and she was thrusting her own to meet me. It felt amazing. She was so wet and so damn tight wrapped around me. I was pinching her nipples again as I fucked her harder now. I told her how close I was but she never had me pull out. I howled as my sperm fired into her tight little cunt.

"I came... I came inside of you," I said as I panted.

"Yes you did big brother," she purred as she pressed her tits to the carpet and raised her ass as high as it could go. "I want you to fuck me again. Oh dear god, you are as hard as steel! Oh yes... oh god yes..."

The rest is a bit of a blur. We fucked for what felt like hours. When I woke up I was in my bed and a bit fuzzy on how I had gotten there. I touched my throat but the collar wasn't there. I rolled over and sis was in bed with me. Her naked ass was pressed against me again. I noticed bite marks on her neck and shoulder. Did I bite her? I guess I had. I didn't feel hungover exactly just fuzzy. I ran my hands over her naked body and she purred in her sleep. I lifted the covers and discovered a few more bite marks on her tits and even her belly. I had lost my virginity to her and now we were fuck buddies.

I let her sleep as I got up to take a much needed piss. I winced as I emptied my bladder. My dick was a little sore after whatever she had put me through. I took a quick shower and dressed in pj bottoms and a t-shirt. I went downstairs and checked the laptop. How long had I been under the influence of the collar? I fired up the program and almost fell out of my seat when I read the numbers. I wasn't angry with Haley, she had set the computer to crunch the numbers and they were astounding. I had been under for three hours with no adverse effects. I double checked my readings but everything appeared to be normal. I looked at a new column of data and sat back in the chair. Sis had actually tracked how many times I had climaxed.

"Fifteen," I said. "Holy shit, I came fifteen times that has to be a record somewhere."

She had also keyed in on when she directed my activity. Not only was she a sex addict but a not too shabby lab assistant. Apparently the collar bypassed the normal limits of human behavior and allowed things like this to happen. She ordered me to get an erection and by god it happened, over and over again. I had been her plaything for three fucking hours! I was surprisingly okay with that. I picked up the tablet and looked at her designs again. Some I had to discard for practical purposes but there were five that I really liked. They fit form and functionality nicely. I imported them and began to render them with very specific measurements and created the first blue prints for my doll collar.

I was down there for another six hours as Haley slept. I had one of the collars down to the millimeter and printed off the schematic. I looked at jewelers at first but decided they might not be able to build what I needed to the exacting specifications. That's when I shook my head and researched 3d printers. I could make the pieces myself and then have them electroplated for cosmetic reasons. The only real issue was the battery life of the device. I decided on a wireless system similar to those used by cellphones. The last part was the trickiest, the locking mechanism. I wanted to be able to lock and unlock the collars via remote or an app. I found just what I needed online.

"You need to eat something," Haley purred as she pressed her naked breasts against my back. "Ooh, is that one of my designs?"

"Yep," I told her as I showed her the digital version of it.

"What is that in the back?"

"A locking mechanism," I told her as I triggered the animation.

"Oh that is so wicked," she said. "That is almost seamless big brother. I ran your numbers for you."

"I see that," I said as I turned to face her.

I cupped her tits and lightly licked her sensitive nipples. I told her how naughty she had been. But I forgave her and let her sit on my lap. I showed her the first new prototype and the printouts. Haley took the computer mouse from me and clicked on a folder on the desktop. It opened and there was a file named models. She clicked on that and there was a list of names.

"Potential women to model your new collars," she purred. "Now we go upstairs and I fix us some breakfast."

"You are right," I agreed. "This is going to be epic with you onboard."

"I will do the sales and you can break them in." She said giggling. "I can't wait to see how this works out."

My Hands Are Tied:

Two weeks passed as I tore down and rebuilt the collar half a dozen times. With each build I got better ideas on how to improve it and add, tweak or just fuck with it. Haley suggested I was putting things off and she was probably right. I had a dozen versions of the collar most of them were identical with the only difference being the cosmetic casing that sis had designed. Two of them were different. One was the Master collar. The other had every setting preprogrammed into it. The rest had only three or four settings at most.

Sis was out with friends and I was home drinking, again. I was pretty lit when the doorbell rang. Damn did she forget her key again? I walked over to the door and opened it. It wasn't Haley it was mom. She frowned when she saw that I was drunk.

"Enter into my domain Lydia," I said calling her by her given name.

"Are you drunk," mom asked and I nodded. "Where is your sister?"

"Out with friends," I said returning to my chair and my bottle. "Have a seat. There's beer in the fridge and wine in the cellar. You know I didn't even know this place had a fully stocked wine cellar until tonight."

"I'll have a beer," mom said as she stalked into the kitchen. "You are paying her way too much."

"You mean Haley, she is earning her keep. She cooks, cleans and is my personal lab rat."

"About that," Mom said bending over to reach for a beer. "You sure these experiments of yours are safe."

"Perfectly," I said staring her ass. "I never realized."

"Never realized what," mom said as she closed the fridge door and opened her beer.

"What a nice butt you have. You must like seriously work out to keep it looking that good." I said only slightly slurring my words.

"Thanks sweetie, you really need to get a girlfriend." She replied laughing. "Ooh, what are these?"

"Oh those are..." I began and stopped. Mom was holding up one of my collars. "You don't want one of those."

"They are so pretty! Did Haley design these?" Mom asked and I nodded. "Ooh this one is gorgeous!"

"Please... stop... don't put it on," I said half-heartedly knowing she wouldn't listen. Click, the collar locked around her neck and powered up. "How do you feel?"

"Oh damn, what is happening?" Mom said her eyes glazing over with pleasure.

"I told you not to," I said as I got up and took her beer and set in on the kitchen table before she dropped it. "How does it feel, tell me?"

"Oh it's like somebody is licking my pussy," Lydia moaned. "UNNNN it's teasing my tight little asshole too. Did you make this?"

"Yep, sit down mom," I said pointing and she sat down.

I returned to my seat opposite of her. I sipped from the wine bottle and watched her squirm. I could've grabbed the remote by my hand and ended it but she looked like she was having such a good time. I asked when the last time she got laid was and she replied 'about a week'. I was thrilled to see her and dad were still an item. That's when I learned dad wasn't her partner; it was her personal trainer at the gym. So that is why she looked so damn good.

"I want you to take off your jeans, place one leg over one each arm of the chair. Have fun, I want to watch and see what all the fuss is."

Mom nodded and made a show of it. She stood up, knelt in the chair and undid them. She slowly tugged them down until I could see her panties. She tugged those down too revealing her soaked slit. So that's where I came out of I thought as she wiggled her way out of those jeans. I swallowed hard as she kicked off shoes and jeans. Lydia followed my directions to the letter.

"You look good mom," I said as she placed a leg on either arm of the chair. "I like the trim job."

"I'm glad," she moaned as she began fingering her pussy.

"Whatcha thinking about," Lydia purred as she stared at the erection in my pants.

"A couple of things," I said as I watched her fingers work her pussy. "I've already fucked your daughter. I am thinking fucking you wouldn't be much worse. I've already crossed one line you know."

I picked up the remote and pressed a button. The bar split open revealing a hidden wide screen television. I pressed a second button and an antiquated piece of machinery appeared just below it. Mom watched all of this with great interest. Her eyes widened when she saw the VCR. She looked at me curiously.

"I like to cover my bases," I told her as she continued fingering her pussy relentlessly. "I thought this might happen so I did a little forensic accounting. It is a fascinating field. You know you don't have any federal or state income tax forms for a stretch of three years."

Mom's face went pale. It took a little digging and not a few bribes to find out why. I hit the play button and there on the big screen was a nineteen year old version of my mother on her knees taking on three guys at once. She looked quite enthusiastic as she sucked one guy off and took the others in her cunt and up her ass.

"Not an academy winning performance but entertaining none the less," I said just as mom climaxed off and on screen. "Damn, I never pegged you for a masochist Lydia."

"That was a long time ago," she said between gasps of breath.

I got up and took out Haley's toy box hidden under the sofa. I set it in front of mom and opened it. I sat back down and took out my cock. I began to stroke while mom lubed up a rather impressive faux cock and eased it inside her pussy. We watched each other as we masturbated. Lydia licked her lips as she fucked herself with the toy. I watched the toy slide in and out wishing it was me.

Could I really cross that line? Sis had been easy, she had shown some interest without the collar. This was mind rape clear and simple. I could turn off the collar's power and see what happened. Nah, I was enjoying the show too much. I could test out the Master collar and give it a whirl. I stood up and walked over to the case holding the collars. Mom's eyes tracked me the entire time. I slipped on the black metallic piece and felt it lock into place. Once it powered up mom let out a soft cry of pleasure.

I could remotely access any and all of the other collars with this one. I could change what program was running or even adjust the speed and tempo of the pleasure they were receiving. Mom's cry was when I deepened the penetration of the phantom tongue inside her ass. I sat back down and watched her. I set the remote down and silently guided her actions. It was untested programming but now was as good a time as ever.

'Kneel on the chair so I can see your ass and pussy better,' I sent and she reacted instantly.

What I envisioned she did. Soon Lydia was on her knees with her ass high in the air working the toy with her free hand. The naughty sounds of her moans combined with the slick sounds of the toy had me hard again in no time at all. The feedback loop told me she was close, real close. I nodded and mom's second orgasm hit her so hard she actually fell from the chair. Her head missed the glass coffee table by inches.

"We need to move this upstairs," I said. "Grab me another bottle of wine and meet me in my bedroom."

"Whatever you want," she purred as she got to her feet.

"Oh and clean up that mess before you come up."

I staggered up the stairs and to my room easily enough. I was going to do it. I was going to cross that line and then make her forget. I had to. She would hate me otherwise and I couldn't live with that. I stripped down and lie on my bed. Lydia appeared equally nude a few minutes later with an open bottle of champagne. She walked over and set the bottle on the night stand. I see where sis got her tits from.

"How big are those?" I asked.

"My tits, they are 38 D's sir," mom purred. "Do you like them?"

"Yep, why don't you wrap them and your lips around something," I suggested.

"I was hoping you'd ask."

She walked to the foot of the bed and climbed on. I watched as her breasts swayed with each movement as she closed the distance to her target. Lydia placed a hand on each of my thighs, opened her mouth wide and took my cock down to the base in one smooth action. God damn mom can deep throat! She did a sort of oral push-up using my cock as the measure of how far down to go. I thought Haley was a talented cock sucker, mom put her to shame.

I stared down as she thrust her head down a half a dozen times before focusing on just the tip for a while. I shivered as I felt her tongue work the head and the sensitive underside of the shaft. That tongue of hers was magical. I was grunting and groaning and she picked up on every image my hungry thoughts conjured up. She reached out and grabbed my hands and placed them on either side of her head.

"Fuck my throat," she growled. "I want you to shoot your load there like the filthy little slut I am!"

Ding, mom's masochistic side just reared its head. I pulled her head down until her lips were once more around the base. I then yanked her head up and down slowly but forcibly. Her tongue worked me fiercely as her cheeks sunk in as she applied suction. Oh damn this was fucking intense! I let go and directed her to use her tits next. Before I lost it I wanted to feel that.

Mom just smiled and adjusted her position. Her saliva was an adequate lubricant and my cock slid between them quite easily. The pillow like flesh felt amazing just below Haley's pussy and Mom's mouth. She pushed them together as she massaged me between them. I was panting as my toes began to curl and I warned her how close I was.
