It's Christmas morning, I can hear the sounds of the house waking as I lie in bed with Rachel's head resting on my chest. I'm having Christmas at my mothers and will be heading to my Dads for New Year, Tammy has gone to have Christmas with her mother and my Dad.

Tammy wanted to come with me and Rachel, I felt meeting my goth girlfriend would be enough for Mom, she still hates my father after all these years and I didn't think having her ex-husband's daughter here would be a good idea. Though she possibly would have got some perverse pleasure from seeing her used as a my submissive sex toy.

Running my fingers through Rachel's hair I think back over the last 10 months and how much my life has changed. How it all began when Tammy asked to move in with me when she started college while looking for her own place, her request for me to teach her how to please men, the way our relationship developed from her doing household chores to becoming my full fledge sex toy.

Rachel stirs opening her eyes, she runs a fingernail down my chest to my cock, giving me a smile before disappearing under the sheet. Thinking about Tammy and the pleasure I have had with her has me hard.

As Rachel sucks my cock I close my eyes thinking about her, my girlfriend that I met in a sex shop where I buy toys and clothes for my sex toy Tammy. What began as a normal relationship quickly changed on her first night with Tammy, now she's Tammy mistress, she has her own wild and kinky habits and is also submissive but no where near the level of Tammy.

"Good morning Clark," Rachel says licking her lips as she reappears from under the sheet.

"Morning Rachel, up for the challenge of meeting my family."

"Oh yes but are they up for the challenge of meeting me."

Christmas day involves a family get together with Mom's sister Amy, her husband Bill and daughter Grace, they travel here each year spending several days over Christmas with Mom before heading off to the beach for New Year. They were here when we arrived last night, we only had time for brief greetings before bed.

We join everyone in the kitchen for breakfast, Mom and Aunt Amy are busy cooking bacon and eggs, we sit with Uncle Bill and Grace at the table. Breakfast traditionally is the start of a day of eating and drinking, Mom prepares enough food to feed a small army and we live on leftovers for days afterward.

This year is no different, after breakfast Rachel, Grace and myself go outside to enjoy the sunshine, I sit at the outdoor table whilst both girls have changed into bikinis and lie on deckchairs on the lawn. Within half an hour of coming outside three plates of nibbles are brought outside by Uncle Bill along with an esky of beer and wine.

I give my Dad a ring wishing him a Merry Christmas then I give Tammy a ring to wish her a Merry Christmas and arrange for her to be in her bedroom when I'll ring her again later.

For the rest of the morning I sit at the table drinking beer, eating snacks and watching the girls sun themselves, they appear to be getting on well together as they lie facing each other chatting. Grace has her back to me, I can't help but stare at her tight little ass in her bikini, imagining what it would be like to fuck it, my cock growing hard along with my imagination.

Just before 1pm Uncle Bill comes outside to tell us to clean up and come to the table for lunch. The usual Christmas feast lies spread out across the table turkey, ham, an assortment of roasted vegetables and salad, various sauces and dressings all of which will be followed by trifle and Christmas pudding.

Mom sits at one end of the table Aunt Amy the other, I sit beside Mom opposite Grace, Rachel beside me opposite Uncle Bill. The girls got changed before coming to the table for lunch Rachel is dressed in a backless dress with a low cut front showing off her cleavage which is accentuated by the tight fit of the dress pushing her tits up, it is also tight around her ass and reaches the top of her thighs. Grace is more conservatively dressed in a loose fitting summer sundress which shows a slight hint of cleavage and reaches to her knees.

I'm pretty sure Mom doesn't think Rachel's dress is appropriate for a Christmas lunch and I know Aunt Amy definitely doesn't approve from the look on her face as she glares back and forward between Rachel and Uncle Bill who's eyes are firmly fixed on Rachel's cleavage.

Thankfully neither of them are the type of person to say anything openly, I do expect Mom will give me some subtle hints later on about what is and isn't appropriate at the dinner table.

As Mom and Aunt Amy clear the table getting ready to serve dessert Rachel leans across to me, "I'm feeling naughty and need a good stuffing like that turkey."

"Hmmm maybe I should spank you for being naughty dressing like that."

"Don't you like it?"

"I do but I'm not sure about Mom or Aunt Amy."

"Uncle Bill likes it."

"He certainly does," looking at him I see him sitting as if in a trance staring at Rachel's tits as if he will be able to make the dress fall off them if he stares at it for long enough.

"Well you better be quick because I know someone else that wants to," she say giving Uncle Bill a smile, "In the meantime you can have some fun with this."

Rachel places a mobile phone in my hand, looking at it I see the app for a lovense toy is open.

"When did you get this?"

"Sometimes a girl just got to buy herself something special for Christmas."

I bought one of these for Tammy making her wear it when we go out in public, I love watching her face and body when I turn it on, the way the different intensity settlings make her act. It's also entertaining to watch people around and the way they look at her when it's on.

Now to have one I can use on Rachel as we sit at the table, this will be very entertaining.

I select the lowest setting as Mom and Aunt Amy serve up the dessert, as I eat I watch Rachel's face, she is giving no indication that the toy is affecting her, I turn the setting up.

"Clark stop playing with your phone at the table."

"Sorry Mom, it's work, finished now," I have set the vibration to maximum putting the phone on the table beside me.

I look at Rachel, nothing, she just gives me a smile.

A noise draws my attention to Grace, she's biting her lip, her face flushed, knuckles white as she squeezes the edge of the table, her body shaking.

"You alright sweetie, your looking very flushed?" Aunt Amy asks, a concerned tone in her voice.

"She's probably just eaten too much, why don't you go and lie down for a while dear," Mom adds.

I quickly open the app turning the toy off, Grace gets up slowly, her legs shaky as she leave the table. I turn to look at Rachel, "Oops wrong phone," she says with a smile.

"What the fuck Rachel," I ask as we sit in my room after lunch, "What was that all about?".

"Little girl wanted to play with the adults."

"What?"

"Well this morning we were talking, I told her where I worked, she was very interested asking a lot of questions, I decided to test the water telling her about Pet."

"You what! You told her about us and Tammy."

"No, I only told her about Pet as a girl I knew through work, what happens to her, the pleasure she gets and gives, I didn't say who from or who to."

I can't believe what I was hearing, I stand staring at her as she talks.

"She became more interested, saying how exciting her life must be compared to her boring life, she wished she was able to live a life of pleasuring and being pleasured."

"And you decided to help her."

"Of course it's the sort of girl I am, I told I had a couple of toys with me and if she liked I would let her use them, I even offered to help her."

"I bet you did," I said smiling as I thought of Grace's tight ass and the various sexual activities that may arise.

"When we were getting dressed I helped her put the lovense into her pussy, when she asked me what it did I told her she would find out at lunch, she was very excited and didn't hesitate for a second.".

"You should have told me who I was playing with."

"Would you have done it?"

"No, well yes but not full strength at the dining table."

"That's why I didn't tell you, wasn't it fun."

"Just next time let me know, now go check on her while I ring Tammy."

Half an hour later I'm lying on the bed naked stroking my cock as I watch Tammy masturbate, she using a new rabbit vibrator I gave her for Christmas. It's a little quirk I have, I enjoy watching them masturbate, watching them orgasm, the only catch is once they start they aren't allowed to stop until I tell them. I enjoy watching them lose control as their bodies are swept by multiple orgasms until they are basically a mindless mess.

As I'm lying there the bedroom door opens, Grace walks in followed by Rachel, the sight of me naked holding my hard cock freezes her to the spot. Rachel closes the door moving up behind Grace ushering her towards my bed.

I put my phone down studying Grace, she's slightly taller than Rachel with her brunette hair tied in a ponytail. Her dress is quite conservative giving little indication of the body underneath it, she has a sweet innocent face with large brown eyes and full lips.

Getting off the bed I pick up my phone walking over to her, she stares at my approaching cock, fidgeting nervously as I get closer. Lifting her chin up I hold the phone in front of her face, by the sound of it Tammy is in the process of having another orgasm.

"Will you do that for me?"

Grace doesn't speak, she's mesmerised by the screen, her eyes open wide as she stares at Tammy. Rachel is also watching the phone screen, her face showing pleasure unlike the shock look on Grace's.

Taking Grace's hand I move it to my cock, she is that fixated on the phone screen I don't think she's aware of anything else until I wrap her hand around my cock and start stroking with it. Her eyes move from the phone to my eyes to her hand and back to my eyes as she realises what is happening, my hand wrapping around hers, squeezing it around my hard shaft moving it up and down along it.

Moving the phone once more in front of her face I ask "Will you do that for me?"

Grace nods her head.

"Take your dress off," I say releasing my grip of her hand.

"Tammy that's enough for today, same time tomorrow," I say as I watch Grace unzip the back of her dress letting it fall to the floor.

Under her dress she is hiding a nice firm body, her best assets still hidden by her bra and panties. Reaching around her body I unclip her bra slowly taking it off to reveal two large firm perky tits with large puffy nipples. I massage each of her nipples between my thumb and finger turning them into hard little rockets.

"Clamps please Rachel."

Rachel goes to her bag pulling out two nipple clamps joined together by a length of chain.

Grace winches as I attach at clamp to each of her nipples, "No more bra and these stay on unless I say otherwise, understand?"

"Yes Clark."

"Good girl."

Turning my attention to her panties I kiss each nipple before running my fingers down the sides of her body, wrapping them in the top of her panties I pull them down as I sink to my knees. Above a perfectly smooth slit is a neatly trimmed patch of hair, I run two fingers along her thin, delicate lips gently parting them to reveal a juicy pink pussy.

Grace's body trembles at my touch, a soft purr escaping her lips as my finger gently runs around the rim of her increasingly wet pussy. Standing up I place my wet finger on her lips, slowly pushing it between them into her mouth.

"Silver bullet please Rachel."

Rachel goes to her bag pulling out a long shiny vibrator, it's about seven inches long and a inch and half wide at it's thickest, as the name suggest it is smooth, silver in colour and shaped like a bullet. Grace's eyes watch Rachel as she approaches turning the vibrator on, the humming noise growing louder as she increases the speed.

Taking the vibrator from Rachel I touch it against Grace's nipples, Rachel is smiling widely while Grace has a look of apprehension on her face as I run the vibrator around each of her tits then down her chest, over her stomach, through her garden of hair coming to rest just above her clit.

"Lift your skirt up Rachel."

With a puzzled look Rachel lifts the front of her skirt up to show her shaved pussy with two lush pussy lips teasingly dangling between her legs.

"Rachel had fun with you earlier your turn to return the favour," I say handing the vibrator to Grace.

Grace looks from me to the vibrator to Rachel then back to me, "What do you want me to do?"

"Fuck Rachel with the vibrator."

"Yes please Grace, fuck me," Rachel says spreading her legs wider.

Grace gets on her knees, she rubs the tip of the vibrator along Rachel's lips, down one lip up the other.

"That's it Grace, nice and slow, no need to rush I'll tell you when."

I have Grace tease Rachel's pussy for about fifteen minutes before instructing her to fuck it. Grace is obedient moving the vibrator as I instruct without question or hesitation, I smile as I think about the fun to come over the next few days.

"On the bed Rachel, Grace get on top in the 69 position."

Going to Rachel's bag I pull out two leather straps, pressing Grace's face against Rachel's pussy I tie a strap around the back of her head and Rachel's ass, I repeat the process with Rachel's head and Grace's ass, securing them together.

Picking up the vibrator I push it into Rachel's pussy, then climbing on the bed behind Grace I push my cock into her pussy. It's feels like it's been an eternity since I was jerking off to Tammy's masturbating, now as I slide into Grace's tight pussy I know I'm not going to last long.

As my cock slides in and out of Grace's pussy Rachel runs her tongue along my shaft, fingers playing with my balls, on the verge of coming I pull my cock from Grace's pussy jerking myself off over it and Rachel's face.

"Have fun girls I'll come back later to release you," I tell them getting dressed as I leave the room.

"Are the girls joining us Clark?"

"No Mom they're not hungry, they are lying down getting to know each other better."

"That's nice dear, well there's plenty to eat if they want something later."

"No worries Mom I'll make sure they eat something."

I leave the girls for about an hour as I expected Rachel is still happily eating Grace's pussy and getting fucked by the vibrator. Given a chance Rachel would lie for hours eating, being eaten and generally fucking, on the other hand Grace is lost in her own world of pleasure and no longer eating Rachel's pussy.

I untie the girls, Grace goes to her room to rest for a while as Rachel and myself join everyone in the living room watching TV. We have a quiet evening with a light snack and several drinks as we sit around chatting.

Everyone slowly drifts off to bed leaving only Mom and myself up, it's nearly midnight when Mom says goodnight going to bed herself. It's a good hour or so since Rachel left, I've been eagerly waiting for Mom to go knowing that Rachel will be waiting for me with a soaking wet pussy.

Opening my bedroom door I find the room empty, looking around the only thing I notice is that Rachel's bag of toys is not sitting on her bedside table, turning around I look in the direction of Grace's bedroom to see her bedroom light shining under the door. Moving to the door I open it taking the scene in, Grace lies tied spread eagled on the bed a vibrator taped against her pussy lips and clit. Rachel is riding the cock gag sticking up from Grace's mouth and wearing a large black strap-on which she is slapping Grace's tits with.

"Ass or pussy?"

Ever since seeing Grace lying on the deckchair this morning I've been dreaming of fucking her tight little ass, it also means I don't have to pull out before I come.

"Ass."

Rachel climbs off Grace's face removing the cock gag and untying her, lying back on the bed she wiggles the strap-on, "Come suck Mistress's cock Puppet."

Grace rolls over on her hands and knees crawling over to Rachel and the strap-on, Rachel grabs her hair pulling her head down onto the cock.

I take lube from Rachel's bag moving behind Grace's ass, stripping off my cock is already hard as I get ready to lube it, applying a generous amount of lube to my palm I spread it over the length of my cock as I stare at Grace's little asshole. After lubing my cock I turn my attention to Grace's ass squeezing lube around her hole, spreading it around the rim and inside with one then two fingers.

"Come Puppet sit on Mistress's cock," Rachel says holding her strap-on upright as Grace sits up, she moves forward straddling Rachel's waist. Grace lowers herself onto the strap-on, I watch as Grace's pussy lips wrap around it, slowly swallowing it until it fully disappears inside her.

Rachel takes hold of the chain attached to the nipple clamps pulling her down and forward, presenting her asshole to my cock. Straddling Rachel's legs I move behind Grace sliding my cock into her ass to moans and squeals while Rachel nibbles and sucks on her nipples. Grace's ass is lovely and tight wrapping around my cock as I push it deep inside her, it's tighter than Tammy's was that first time since no butt plugs have prepared it.

Grace's body rocks back and forward as Rachel and I pleasure ourselves with it, my cock pounding deep into her ass stretching her tight virgin hole as Rachel's strap-on stretches her pussy, driving her to multiple orgasms, her screams muffled by a pair of panties stuffed in her mouth.

I feel the strap-on as I fuck Grace's ass, rubbing against it as I move inside her, with each of her orgasms her ass muscles spasm around my cock, squeezing it. With a grunt I come, Grace lets out a muffled squeal as my cock explodes inside her, throbbing deep in her ass as I pump it full of cum.

"Yum dessert time," Rachel says wriggling from underneath Grace, "Strawberry and cum my favourite."

I watch Rachel's tongue working Grace's asshole, licking around and inside it scooping up every drop of cum. Rachel loves strawberry flavoured lube, it's the only flavour she has and uses, mix it with cum and she's in seventh heaven. Nearly every session with Tammy involves anal with lube and cum, and it's looking now that for the next few days Grace's ass will be satisfying that fetish.

Once Rachel is satisfied with her cleaning she begins lubing Grace's ass again and her strap-on cock, meanwhile I have moved in front of Grace's head and have her sucking on my cock.

We split roast Grace, Rachel and myself working in a perfect rhythm as we pound her, thrusting deep into her ass and mouth in unison. Grace's body sandwiched between our cocks, the sound of her gagging as my cock slides deep down her throat filling the room.

My cock swells with each thrust until I come, pulling my cock out of her mouth I shoot cum over her face. Rolling Grace onto her back I move between her legs eating her wet pussy while Rachel licks my cum off Grace's face before straddling her face to grind her pussy against it.

For the next couple of hours we fuck Grace or more accurately Rachel fucks Grace. Rachel is in her element as she uses her strap-on, dildos, vibrators taking Grace to the edge of an orgasm only to stop, denying her the pleasure, each time leaving her begging for more.

I enjoy watching Rachel's control and domination, rewarding her by fucking her ass as Grace eats her pussy, afterwards Grace clean my cum from her ass while Rachel has a vibrator in Grace's ass and rubs another one against her clit.

Grace doesn't come to breakfast, Aunt Amy says that Grace is very tired, that she didn't get a lot of sleep last night and is going to stay in bed for a while longer and sleep some more. Rachel has a smirk on her face, I nod my head giving her a little smile.
