A Medallion and a Sister

As more of my length invaded her mouth I couldn't hold it any more and I came hard. Her tongue was lashing the underside of my cock as I erupted. My hand kept her head down, though there was no need, as I could feel my sister swallow my first thick load of cum. I was growling as my orgasm continued to take over my body, I thrust my hips up desperate for my whole length to be bathed in her warm mouth.

Load after load flooded my sister's mouth and she kept on swallowing hungrily. I could hear and feel her murmuring happily around my prick. The feeling was so intense and I wanted it to last a lot longer but all too soon it was over. With my last shot of cum I feel back and removed my hand. I was trying to regain my breath when Estelle emerged red faced, breathless and her hair in disarray from beneath the covers.

"Are you satisfied Sir?" She asked. Some of my cum was on the bottom of her lip which I gladly pointed out and with a flick of her tongue she had it in her mouth.

"Yes I'm satisfied." I answered with a feeling of satisfaction. Next time, I promised myself, I would last longer.

Noticing the time we hurried to get breakfast eaten, lunch sorted and clothes on before we left the flat. As soon as we got to the museum we split up, I went to my office whilst Estelle went to the basement. I still had a couple of boxes of stuff that needed to be typed up so for the next couple of hours I was busy working when I heard a trolley in the hallway and I knew it would be my sister.

"You finished with all these boxes then?" Estelle asked as she entered my office.

"Just got these two left..." I stopped talking as I notice my sister unbuttoning her blouse and shrugging it off her shoulders. I suddenly realised the command I had given the night before. I hadn't been specific with my command and seeing as the two of us were alone she was taking off her top.

"How many you got for me this time?" I stuttered trying to continue with normality as her amazing bust encased in her sports bra came into view.

"I only brought up four this time, there's not many left in the store room and I've already done the cleaning." She breathed as she dropped her bra to the floor. "I'm a bit worried I'm not going to be needed here soon."

"You've been searching for other jobs though right?" I asked licking my lips at the sight of her erect nipples.

"Yeah course but no one replies to my applications and this job pays better than anything I'm qualified for... I don't want to move home" she said finishing with another sigh.

"Hey don't worry, it's not like you haven't got a job and besides as long as I'm in London you can live with me." Obviously there was good reason for me saying that and as I thought about this morning my dick responded.

"I'll have a word with the boss and see what he's got in store for the both of us." She smiled at that. "But right now I want you to do everything I tell you until I cum."

Estelle got to her feet and faced me. All she was wearing now was her black skirt and as much as I wanted that off I thought that might be pushing it a bit too far. I sat back in my chair and pushed it away from the desk giving myself some room.

"Come around here and sit on the desk." I said and my sister was quick to move. She sat on my desk facing me, her heavy tits raised with each breath as she waited for my next command.

Unable to resist the temptation in front of me, I took her right breast in my hand and squeezed. The soft plump flesh gave way and my sister groaned in response. Quickly I moved my thumb to her nipple playing with it until it hardened.

My sister smiled at me whilst she moved her hands to my trousers. The movement was unprompted but she knew she had to make me cum. With a deft touch she had them loose and her fingers delved through my boxers to grip my shaft.

"Oh that's good! Get on your knees underneath the desk and give me the best blowjob you can... don't forget my balls!" I chuckled as Estelle moved under the desk, her hand still on my cock pulling me towards her.

"Oh, that's perfect." I said when I felt the warmth of her mouth around my cock. She sucked the head for a while, her tongue flicking the slit before pushing down taking my entire length in her mouth. I could feel her hot breath on my groin and her saliva dripping to my balls as she continued to give me my second blowjob of the day.

It was when she had my balls between her teeth lightly biting down and her hand stroking my shaft that the door to my office opened and the boss came in.

"Ah here you are. Working hard I see!" Harry Price beamed at me.

I could only stutter and squeak in response. My hand tried to push my sister off my cock but she was still under command to finish me off so as my boss too a seat opposite me I felt my cock once again engulfed by her mouth.

"Now I wanted to talk to you about the future. I see you're close to finishing what I asked." He waited for a response but all I could do was nod.

The desk had a cover so he couldn't see my sister's feet and I pushed my chair into my desk hiding any trace of her but my red face and the tight grip my hands had of the desk must have given something away.

"Well as I said you look close to finishing this project so I want to see whether you wanted to stay here for longer?" He smiled at me, apparently oblivious to the bliss my sisters mouth was giving me.

"Oh yes absolutely," I breathed, nodding vigorously. Estelle was holding the tip of my cock in her mouth whilst her tongue rubbed the underside. The chair and my trousers were now soaked but I still wasn't close to cumming especially with my manager right in front of me.

"That's just what I wanted to hear. I've been reading what you've written and I must say it's very good. I've shown some of my fellow peers and a number have expressed interest in you doing the same for them." He paused again to see if I said anything but with my sister now dragging her teeth along my shaft I just shivered instead.

"Anyway when you've finished with this I want you to write a tour for my museum. I want an audio walkthrough for the exhibits, we get lots of foreign people come and I need them to spend money here! So a guided audio tour is the best way for us to make a profit."

"Oh... absolutely. No problem." I was sweating now. I kept my words short because I knew that I my voice sounded strangled.

"But I'm afraid Estelle might not have a job. I know she does exactly what you ask but I just can't see what else she does." Harry said apologetically.

At that exact time Estelle was on her knees, my balls in her hand and my cock buried in her mouth as her tongue flicked the bottom of my shaft. I was so close but his words had pulled me back.

"She works incredibly hard and I need her. Her mouth is fantastic..." I stuttered as my boss gave a strange look. "I mean if I've got writers block she helps me express myself. You talk about a tour guide, she could be one and so will I, I'll... I'll even do the tours dressed up."

"Deal!" Harry beamed with delight then a devious grin played across his face. "Though I'll be deciding what you wear. I'll have your new contacts written up but I want theses boxes done by the end of the month then you can get started on the tour. Your sister owes you big time I hope she makes it up to you!" With that he stood and strode from the room.

I let out a loud groan as the door shut. Pushing back my chair my sister followed and for the first time I saw her pretty face eagerly sucking on my cock. She looked up at me, my prick hidden in her mouth, her mascara running and her lipstick smeared all over but as hot as that was it was lustful look she gave me that made me explode.

"Christ I'm cumming!" I stood, my hands dug into her thick blonde hair as I felt my cock push into her throat finally making my sister deep throat. Looking down at my entire length buried in her mouth I came hard. Estelle had her hands on my bum gripping me tightly as she gagged and swallowed around my erupting cock.

"Oh fuck, take it. Take it all. Yes, yes!" I thrust again and again; face fucking her as I sprayed huge ropes of cum with each thrust. My legs were starting to wobble but still more spunk came, feeling too weak to stand I dropped to my seat and Estelle stopped sucking instead she gave my sensitive cock long soothing until she had swallowed all my cum.

"Are you satisfied Sir?" She asked licking her lips, sitting back on her legs and looking up at me.

"Oh definitely! But you'll have to clean yourself up before you leave the office." I replied and handed her some tissue from my desk drawer. She took them and opened her phone to the camera setting as she went about cleaning up her face.

As she was sorting her make up I could only pant in my damp chair. My eyes were shut and I had a stupid smile on my face as I luxuriated in the post cum feeling.

"So you'll have a talk with the boss about me then too?" Estelle asked pulling me from my stupor.

"What?!" I replied bewildered. I looked at my sister confused, she was sitting on the other side of the desk still topless but her trousers back on almost a mirror image of where she had been twenty minutes ago.

"You said you'll talk to the boss about us, don't you remember? Just don't forget about me. Otherwise I'll be hanging around the flat all day and you really don't want that!"

"I..." I stopped myself and thought about what I was going to say. If I reminded her about what happened would she remember it all? I had no idea so I played it safe. "Of course I won't forget you! I'll give him a call now."

Picking up the phone I pretended to dial his number and proceeded to have a one way conversation.

"...Um well I'm not sure about that but if it's the only way we can both keep our jobs then I suppose I'll have to do it! Thanks Mr. Price." I put down the phone and smiled at my sister.

"So what did he say? Have I got a job still?"

"Yep, we both have jobs. I'm going to be creating an audio tour guide and then me and you are going to be tour guides though we will have to dress up!" I laughed at the incredulous look my sister gave me.

"Dress up? As fucking Aztecs?! Why the fuck does he want us to do that?" Estelle asked, shaking her head in disbelieve. I was about to reply when she picked up a picture showing an artistic interpretation of a Mayan man. "Oh this is why! Harry fancies you and having you walk around topless will turn him on!"

The irony of her saying having me topless would turn someone else on, when she herself was topless and turning me on, was not lost on me. I let her laugh at her little joke mainly because I was enjoying the show as her firm bust wobbled in front of me but I was also thinking of how to find out just what was going on when I had her under control and then I had an idea.

"Wait! Is that the time? Time is flying by today!" I asked looking at my watch.

Estelle glanced at the time before replying. "I swear it was earlier than that, you know I've been like zoning out. I try to think about what I was doing whilst zoned out but all I remember is feeling satisfied... Weird, right?"

I didn't reply but it made me feel a lot better knowing that my sister felt good about what I was doing. I was tempted to have her back on her knees pleasuring me but it was lunch time and with a deadline for having the paperwork typed up looming I really did need to get on with some work.

The rest of the day went uneventfully, it was a Monday night and that meant I had football practice so after leaving work I didn't see my sister until I got back late in the evening, muddy and wet. I had spent the entire training session thinking of how far I should take it with Estelle. I knew I wanted to fuck her but I didn't know what the limit was of the medallion. It was a complete unknown and I really didn't want to command her to fuck me and her say no. Just thinking of her meant that I had to reshuffle my pants more than once.

Opening the front door to our flat I saw my sister sitting on the couch watching TV. As soon as she spotted me she pulled her bra and pyjama top off in the same motion.

"Are you satisfied sir?"

"Fuck yes!" I said marvelling at the size and firmness of them. I don't think I could ever get tired of that view. Realising I was dripping sweat on the floor I dumped my stuff in the cupboard then peeled off my clothes as I waited for the shower to heat up.

"Can you heat up some food for me please Estelle." I shouted as I stepped under the hot water. I heard her agree then move into the kitchen. Standing under the shower my mind drifted back to my earlier thoughts of my sister. I could hear the microwave whirring and Estelle singing to herself. Biting my lip I made up my mind.

"Estelle!"

"What?"

"I want you to take off your clothes and come help me in the shower."

A couple of seconds passed then the bathroom door opened and there stood my stunning sister absolutely naked. Despite cumming twice that day my cock was rock hard as my eyes travelled up and down her body.

Due to the lack of space in the flat our bathroom was a wet room with the shower in the corner so it was easily large enough for two people. I watched open mouthed as my sister walked towards me her tits swaying lightly with each step. Without saying a word she picked up the shower gel, spurted a large glob onto her hand then slowly began to rub it into my chest.

"That feels great!" I groaned as both her soft hands scrubbed my body. As she busied herself with my chest and arms, I took her breasts in my hands and started to enjoy myself, squeezing and massaging the large orbs.

It didn't take long for her nipples to be as hard as my cock but she pushed me off, turned me around and started to wash my back. I couldn't help but laugh, my commands were taken incredibly literally. Eventually her hands moved down to my bum then I felt her work over my legs.

There wasn't much left of me that had yet to be cleaned and once again I was forced to turn around. She made short work of the front of my legs and before I knew it her hands were on my shaft. There was no playing though, she quickly scrubbed it before moving onto my balls then she stood and faced me ignoring my hands which had inevitability moved to her chest.

"Are you satisfied Sir?"

"No, I want to clean you." I said firmly and immediately she dragged her bust from me. Taking the shower she squeezed a load of soap into my hands.

I wasn't nearly as soft as she had been and I took far longer on her chest. Her spongy globes were squeezed, pulled and rubbed with special focus on her nipples until I could start to hear her breathing become shorter.

"Tell me what you want me to do now." I asked my hands cupping her tits.

"You need to do my neck and back." She replied turning around and flipping her long blonde hair to her front. Quickly I scrubbed her neck and back then hunched down on my knees to bring myself eye level with her magnificent arse.

I could resist it and I leant forward to kiss her muscular bottom. Estelle gasped above me and pushed her arse towards me. Pulling her cheeks apart I moved my hand between them and began soaping up the treasure hidden inside.

Estelle now had both hands on the shower tiles keeping her balance as the hot water rushed down on us. Continuing to kiss her cheeks my soapy hands rubbed her arsehole then moved to her hot pussy. I could feel the heat and with my middle finger pushing onto her clit my thumb pushed inside her arsehole.

"You need to clean my clit properly. Scrub it hard." Estelle demanded her eyes locked on my fingers playing with her pussy. Dropping a hand to her breast she pinched her nipple and gasped as I did the same to her clit.

I could feel her pussy getting incredibly wet and I knew it was time. Kissing her arse again got to my feet and grabbed hold of her hips pushing her forward. With her arse thrust up towards me I licked my lips at the unbelievable sight in front of me. Squirting more soap on my hand I smeared it around my cock making it slippery.

Estelle was looking at me and I could see the desire on her face but she didn't say anything. With my hand holding my shaft I moved it underneath her pussy before releasing it to spring up and slap her lips.

"Fuck! Do that again!" She demanded and I was only to happy to oblige. This time I must have hit her clit because she jumped forward and loudly moaned.

Drawing back I took hold of my prick and aimed it a bit higher. My initial thrust missed and my cock thrust between her plump pussy lips rubbing against her clit. We both groaned in unison, the heat and soft lips felt incredible and again I was close to cumming.

Biting down on my lip hard to try stop the pleasure overwhelming me I managed to regain some control. Trailing my cock up towards her cunt I could feel the heat. With a grunt I thrust forwards, the soap had done its job and the head of my thick cock penetrated her tight hole.

"Holy crap, this is amazing." My voice cracked as her tight wet pussy flexed around my cock head. With my hand now on her hips I drove forward burying my prick inside my sister causing a loud moan to escape her lips.

"Tell me what you feel, I want you to cum." I commanded, there was nothing more sexy than having a woman tell you how good you felt inside her and I wanted my sister to cum whilst I was fucking her.

"Fuck, oh my god you feel massive inside me!" She squealed as I started to pick up the pace. The sound of our bodies slapping against each other filled the small bathroom. I saw her reach for the shower head and turn the nozzle until it was on a single jet then she dropped it to her clit.

I was entirely inside her, the heat and soft tightness of her pussy felt incredible around my prick. Pulling my shaft from her I saw her cunt clutching me not wanting to give up my cock and I groaned at the sight. Driving back I forced my prick back into the warmth.

"Oh fucking hell, I'm cumming." I cried, the tendons were straining in my neck as I began to fuck her perfect pussy.

Estelle grunted and groaned as my thick cock thrust in and out, the shower head was washing over her clit bringing her closer to her own orgasm. I was picking up pace my strained moans joining hers and then with a final thrust I buried my cock inside her and came.

"Yes. Yes. Yes!" I roared. My fingers dug into her hips, as I pushed her up against the tiles causing her tits to flatten out. Biting her neck I jerked against her arse moaning in her ear as spunk flooded her insides.

I could feel her drop the shower head and her fingers were eagerly rubbing her clit until she tensed.

"I'm cumming! Oh yes I'm cumming!" Estelle gasped as my prick embedded inside continued to spew cum until finally I had nothing left to give.

Grinding her arse against me she dropped her hand and breathed heavily as with a pop it fell out limply. Staggering back I sat on the toilet, my cock twitching as it softened. Estelle slowly turned around and looked at me.

"Are you satisfied Sir?"

"Jesus," I said, slowly I got to my feet and pulled her into an embrace. I held her, one arm wrapped around her back and the other resting on her bum. Her hands were wrapped around my lower back as she breathed heavily against me.

"I'm satisfied!"
