"Clark I need your help."

"How can I help you Tammy?"

Tammy is my half sister, she's about 8 years younger than me at 19, a couple of months ago she moved in with me when she started college. Her plan to find a part time job and eventually rent a place of her own, until then I agreed she could live with me.

I never had much to do with Tammy only seeing her at Christmas and the occasional family event. My parents separated when I was three, I lived with my Mom and Dad took his secretary, a ditzy 19 year old blonde half his age to another town. I only visited Dad a couple of times a year, he was never really interested in children, not unless they were 19 or 20 year old females, it felt over the years that each time I went there Dad had a new girlfriend.

It was around my eighth birthday when I overheard Mom talking with one of her friends about Dad getting one of his skanks pregnant, not that I knew what a skank was or even what pregnant really meant.

Mom was never kind when talking about Dad or his girlfriends, even now she hasn't anything nice to say and I avoid mentioning him. At the time I was due to go there just after my birthday for a visit and Mom wasn't sure if it would be appropriate.

Eventually Mom agreed to let me go, not that Dad really cared one way or another, it was more a case of him getting one up on Mom. His latest girlfriend was Carol, I was surprised when I first saw her as she was fat, still young but she had a big fat belly unlike all of Dad's previously girlfriend who were skinny. I didn't connect what I overheard Mom talking about and Carol's size until later when I got home and Mom asked me about my time away and about Dad's girlfriend. When I told her she was fat Mom giggled before telling me she was not fat but was pregnant and had a baby growing inside her.

A couple of months later Tammy was born, she would have been about 6 months old when I next saw her around Christmas. This became the trend of my relationship with Tammy, I would see her around my birthday for a week and at Christmas for a week and on special occasions.

Once Tammy was old enough Dad shipped her off to an all girl boarding school where she remained until she graduated.

I was surprised when she first asked me if she could move in, I never considered us close even though for those two weeks each year I was her constant companion. In hindsight I suspect I did form a bond with her no matter how unintentional it was, I had a way that made her feel special when I visited, devoting most of my time to be with her. In a way I was the only male figure she really established a relationship with, Dad was there but he was always distant, never bonding with her.

It wasn't until after Tammy moved in that I started to notice her differently, she is no longer that chubby little girl I used to play with, she is now blossoming into an attractive young woman.

I study her closely, not for the first time as she stands in the doorway of my bedroom, my cock giving a twitch under the sheets. It's about 10pm, she is wearing a little pink nightie, the light behind her silhouetting her figure through the thin fabric.

It's not unusual to see her wearing this morning and night, other times she runs around in just her bra and panties, I don't think she's teasing me, I think she's just very comfortable and relaxed around me.

As for me I'm between girlfriends at the moment, I find Tammy's body very arousing and have begun regularly jerk off as I think of her.

She's just under six foot tall, her height come from a pair of long, sensuous legs, her ass a juicy firm peach ripe for the picking. She has wavey honey blonde hair which cascades down to below her shoulder blades, a delicate face with crystal blue eyes, a little button nose and thin red lips. Her body petite with delicate breasts, firm and perky with little rosebud nipples which poke out against her tops, a smooth flat midriff and slender waist.

I roll over onto my side to face her, propping myself up on my elbow and hiding a large erection under the sheet.

"How can I help you Tammy?"

She walks across sitting on the side of my bed, I move slightly to ensure there is no accidental bumping between her ass and my cock, which feels like it is growing bigger and harder as I smell the fragrant scent of her perfume.

"I want you to teach me how to make a man happy."

"What... what are you talking about Tammy?"

"I've always been told my purpose is to make men happy but I'm not sure how to do it."

"Who... who told you that?"

"Everybody, whenever I made too much noise at home Daddy always said a good girl sits silently in the corner, only speaks when spoken too and does what she is told without question. He said I was lucky to have a mother that knew her place otherwise I'll be living homeless on the streets."

I could imagine Dad saying that, he is very chauvinistic, one of the many reasons him and Mom broke up. I remember when I visited him everything was very structured and streamlined, his girlfriends always seemed to be that one step ahead of him having anything he wanted ready before he asked for it. I must say I was impressed with how smoothly his home ran in comparison to mine, which felt like it was in chaos most of the time.

"Mommy would tell me I must always do as Daddy says without question, he is the man of the house and in charge. If you behave he is happy with Mommy but if you are naughty he punishes Mommy."

That brought back other memories, of times when one of his girlfriends did something he disapproved off I would often laugh and say that Daddy should spank her. Dad would rough my hair saying he would be doing that and more, I remember the girlfriend always had a scared look on her face and immediately became extra friendly as if trying to get back into his good books.

"Even at school all the senior teachers were men and the governing board were all men, we were taught to respect them, whenever they entered the classroom we had to stand up and lower our eyes not looking at them unless asked a question. In the junior years they ignored us, only coming to the classroom when they wanted to have a meeting with our teacher, they would take her away leaving someone else to finish the lesson. Only in the senior year did they hand pick certain students, they were always the older 18 year olds that went with them for special lessons, unfortunately I wasn't old enough to find out what these lessons were and the girls never said anything other than they were being taught how to be more useful."

I never knew what school Dad sent Tammy to, all he said was it was a special school to teach her how to act as a young lady. From Tammy description it sounds like a very arachidic misogynic place, the sort of place that I thought disappeared years ago.

Tammy places her hand on my chest as she looks into my eyes, "Will you help me Clark, I feel... I feel as if I'm missing something in my life and need your help to find it."

I should have been shocked, appalled to think that this young woman has been indoctrinated over the years to think that her purpose in life was to be a slave, a sexual slave for men. But I wasn't, I was turned on by it, it's like some of the porn I like to watch with older men and submissive young women and maybe, just maybe I'm more like my father than I realise or want to admit.

"Let me think about it," I say, Tammy's leans down kissing me on the lips.

She smiles standing up, I watch her leave my room before taking hold of my cock and jerking off.

After thinking about it for a couple of days and looking at Tammy in a whole new way I agree to her request. Now I'm not sure how far Tammy will actually go or even how far I will actually push her, I decide to start with something safe and simple.

"Tammy your first lesson in making a man happy involves house work."

"Of course, Daddy's very particular about what Mommy has to do around the house."

"Right so from now on you will prepare all meals, do the cleaning and washing. I expect dinner ready when I get home from work, all my clothes washed and ironed, and the house spotless."

"Yes of course Clark, as you wish."

For the next couple of weeks everything is perfect, each morning after my shower I'm served a cooked breakfast, each night when I get home from work my dinner is ready, all my clothes are washed, ironed and neatly put away and the house is spotless. Tammy still goes to college as well as doing her chores, she is very happy that she is pleasing me.

One thing I have noticed over this time is Tammy has stopped making decisions, she asks what I want, what she should wear or do, she seeks my permission before she does anything and craves approval afterwards.

I decide to take things to the next level, currently the only action I'm getting is from my own hand time for a new hand or more accurately a mouth.

Tammy only wears her little nightie around the house and nothing else, I sit on the lounge watching her clean the kitchen after dinner admiring her bare ass each time she bends over. "Tammy come sit beside me," I say as she finishes in the kitchen.

"Yes Clark."

I take in her body as she sits down, her nightie rides up giving me a lovely view of her sexy long legs and a glimpse of her perfectly smooth pussy. The nightie is see thru, working my eyes up I study her tits and perky nipples, my already hard cock getting harder.

"Ready to learn something else that give men pleasure Tammy."

"Yes please Clark."

Putting my hand on her neck I move her head to mine, I kiss her gently on the lips at first, slowly increasing the force of my kiss as I massage the back of her head and neck. As I force my tongue between her lips I slide my free hand down the top of her nightie to her tits. My hand moves back and forward between her tits squeezing and rubbing them, I stop kissing her moving my mouth to her neck.

Her nipples are like little rocks as I rub them between my thumb and finger, she moans softly as I begin nibbling on her earlobe, my tongue playing with her piercing.

"Unzip my pants Tammy," I whisper into her ear, her hand runs along my hard cock to the zipper, her palm pressing against it as fingers grab hold of the zip pulling it down. I run my tongue around her ear, "Now take hold of my cock and pull it out."

I wrap my hand around hers, squeezing her around the shaft of my cock, gripping her neck I force her head down over the top of my cock. "Spit on It," I tell her, I watch as a stream of saliva lands on the head of my cock running down the shaft to her fingers. I move her hand up and down spreading the saliva over my cock, I keep telling her to dribble on my cock until it is covered in saliva.

I release the grip of her neck but her head doesn't move, she holds it over my cock staring at it as I move her hand up and down the shaft at an increasing pace.

"Lick the tip," a twitch of my cock and a droplet of precum appears on the tip, a gasp of breath signals Tammy seeing it appear. Her head lowers, a warm breath of air flows over the head followed by the feel of the rough skin of a warm wet tongue caressing the tip.

I place my hand on the back of her head pushing it down, her lips parting as they glide over and around the head. Holding her head I move her hand along my shaft quicker, her lips locking firmly around the top as her tongue caresses it. I pump my cock with Tammy's hand until I come, my cock exploding in her mouth filling it with my cum.

A new chore for Tammy begins, on my return from work each day Tammy must give me a blow job.

Now that I have broken the sexual barrier I move things along quickly, the following week I come home to find Tammy on her knees waiting for me. As she reaches for my crotch I take hold of her hand, lifting her to her feet I kiss her.

"Go serve up dinner, you will learn something new later."

"Yes Clark," she says smiling

I watch Tammy cleaning up admiring her body through her nightie, tonight is the night, it's the night I fuck her. Finishing up she comes to the living room standing in front of me.

"Take your nightie off Tammy."

"Yes Clark,' she says lifting it up over her head.

I run my eyes up and down her body, 'gorgeous' I think standing up, stepping close to her I say "I got a present for you."

"Oh goody, I like presents, what is it?"

Reaching behind my back I pull a collar from my back pocket. I've been watching a lot of Dom-submissive porn lately, all the submissive girls wear a collar to show they are owned, it's time to make Tammy mine.

"Do you know what this is?" I ask dangling the collar in front of her face.

"A collar."

"And what does it mean?"

Tammy has been watching the same porn as me, part of her education as to her role and purpose. She knows what it signifies I'm just reinforcing it and I guess making sure she is accepting of her new life.

"It means I belong to you."

"Yes you belong to me in body and soul, you will do everything I tell you without question, you are no longer a independent person, you are my property to use as I see fit."

Tammy didn't say anything, she just stares at the collar, her eyes following it movement as it swayed from side to side.

"Do you accept that life Tammy, do you accept this collar as the symbol of your unquestioning obedience to me?"

Tammy takes the collar from my hand placing it around her neck, smiling she does it up, "Yes Clark."

Taking hold of her chin I tilt her head back kissing her on the lips, "Good girl, now on your knees." Reaching around to the lounge I pick up a leash, attaching it to her collar I lead her to my bedroom on her hand and knees. Once in my room I unzip my pants pulling my cock out, Tammy squats on the floor looking up at me, waiting for instructions.

Tonight is not only a special night for me but also Tammy, tonight I take her virginity, tonight will be about me gently pleasuring her. Lifting her off the floor I lie her on the bed, removing my clothes I climb on the bed beside her. I kiss her lips and neck as I massage her tits, my fingers twerking her nipples. I spend my time pleasuring her body with my mouth and fingers, she moans loudly, her body quivering with orgasms.

Moving between Tammy's legs I put a condom on my cock before slowly entering her pussy. Tammy moans again as I move back and forward inside her, slowly moving my cock deeper into her pussy each time. I gently fuck her as my own orgasm grows, her tight pussy spasming around my cock, pleasure written over Tammy's face as she has multiple orgasms. I come in her pussy, my cock throbbing as I pump cum into the condom triggering another orgasm for Tammy.

After tonight I make several new rules for Tammy, she no longer wears clothes at home, the collar never comes off and she goes on the pill, next time I fuck her I won't be wearing a condom.

Over the next couple of weeks it's a blow job on coming home and a pussy fuck at bedtime, life is good, the sex is good, Tammy is watching a lot of porn learning many new ways to pleasure me.

It's time to prepare Tammy's for her next lesson when I take her anal virginity. Also I want to show my prize off, I want everyone to know I'm fucking this little hottie and she's mine, all mine.

Time to go shopping.

I've been going to a little sex shop for the past month or so since I started having sex with Tammy, it was there I bought the original collar and leash, since then I have added nipple clamps, fluffy handcuffs, dildos and a lovense toy to my collection.

I enjoy using the various toys to edge Tammy, making her beg me for permission to come, the dominance adding another level to my pleasure. I have only done things with Tammy around the house, now is time to take my dominance to a new level showing her off to the world and first stop is a trip to the sex shop.

Tammy is wearing a tight white blouse showing off her cleavage, her tits straining to burst free of the top, nipple clamps obvious for all to see. The blouse is tied up to show her flat, firm stomach and the single metal chain running from underneath it, over her stomach and under the top of her skirt. Her skirt is a short black one which barely reaches below her ass cheeks, a pair of black stockings cover her long legs, suspenders running over creamy thighs from under her skirt to the top of her stockings, a pair a six inch stilettoes adding to her height. To finishes off her blonde hair is tied in two pigtails and she wears bright red lipstick.

I know she looks like a two bit hooker but she's my two bit hooker, women glare at her, men lust after her. Walking down the street I let her walk unleashed, a step behind me with her eyes down fixed on my feet. As we enter the shop I only see two employees behind the counter, a young women and a middle aged man.

Both look at us as we enter, though I would say Tammy is attracting more of their interest than me, I attach the leash to her collar, she immediately drops to her hands and knees and I led her over to he section of the shop containing various clothing items and costumes.

To be honest the last few months or so have changed me, I never saw myself sexually objectifying a young woman as I have with Tammy and I'm enjoying it. The power, control is exciting, my own private fuck toy willing to satisfy all my needs no matter how kinky they are becoming and now showing her off in public like this is even more exciting, I'm finding it arousing.

"Can I help you with anything?"

The young shop assistant has come across while I've been looking through the costumes, Tammy is quietly sitting on her heals watching me.

I've seen the woman before on my previous visits, she is attractive with her what I assume is a goth look, dressing sexually with black clothes that flaunt her firm big tits and juicy ass, she's about five foot or so tall and wears platform boots which add another six inches to her height. She has short jet black hair, long black eye lashes, black mascara, black lipstick, a stud in her nose, a piercing in her bottom lip and a black lacey collar.

"I'm looking for a couple of outfits she could wear out," I really not 100% sure what I was looking for, I'm hoping to recognise it when I see it.

"Hmm something sexy and slutty," she says as she turns to study Tammy more closely.

"Yes."

"Come over here I have some nice leather outfits that always turn heads, by the way my names Rachel."

"Thanks Rachel."

I follow behind Rachel admiring her ass wriggle in the tight leather skirt she's wearing, leading Tammy along on the leash.

"Can It stand up umm.."

"Oh sorry Clark, my name's Clark."

"Yes good, Clark can It stand up."

I pull the leash, Tammy stands up.

I watch Rachel look through the clothing, she has given no indication that she finds my relationship with Tammy unacceptable. If anything from the way she talks about Tammy makes me think she approves of it.

Rachel has selected four items of clothing, two black, one red the other green, she holds each one in front of Tammy's body. "I think these would suit your needs, we have change rooms at the back of the shop."

I glance in that direction then back at Rachel, "No need she can try them on here."

Tammy doesn't hesitate for a second quickly removing her clothes, I watch Rachel's expression as her eyes wander over Tammy's naked body studying the chains running from her collar to clamps on her nipples and clit.

Definitely no sign of disapproval.

"Some of the items I previously purchased from you Rachel," I say running my finger along her tit to the clamp, then along the chain giving it a slight tug.

"Mmmm.. suits It."

I'm intrigue by Rachel's constant referral to Tammy as 'It', a thing rather than a person. I don't dwell on it for long as my attention is drawn to a small audience which has gathered, the other shop assistant and a couple of customers now stare in our direction looking at Tammy.
