Step Sister's Secret

All people are over 18.

------------------------------------

This is a stand-alone story and is before I was ever married.

------------------------------------

Back when I was 8 years old my mum and dad split. It was all pretty civil, they just wanted different things in life and although I was upset at the time I don't think I really missed out on too much. I got to spend quality time with both of them and they both made an effort to come to my soccer games etc etc.

Inevitably they both met other people and ended up getting married. Things were so good between them that they both even attended each others weddings.

My dad married a woman called Sylvie who had two sons. We all got on well enough together but I wouldn't say we were best of friends.

My mum married a man called Derek. He had a daughter called Nicole who was a few years younger than me.

It was my mum I ended up living with as she was closer to my school and college so it made sense.

Nicole also lived with us as Derek was a widow. She had lost her mum in a car accident a number of years ago.

After my mums wedding things changed quite a bit for me. Instead of it just being her and I we now had Derek and Nicole living there too.

Things were slightly awkward at the start but with a few ground rules set everyone settled in quite well.

I didn't see much of Derek as he worked long hours.

At first I didn't see much of Nicole either. She was either at school or studying with friends. I was out with my mates or studying for college so we only saw each other in passing.

That all changed whenever Nicole finished school.

She wanted to take a year out and earn some cash so she could go travelling.

Her dad was all for it as he didn't have a degree and was of the opinion that life lessons are worth more sometimes that a degree.

Nicole was 18, five years younger than me.

While she looked for work, I had recently started my first full time job after leaving university.

A lot of times when I came home from work Nicole would have been the only one there. Both my mum and Derek would have been working late or out with friends.

We chatted about how her job hunt was going and what she had been up to all day.

Quite a lot of times when I came home she was only wearing a pair of skimpy shorts and a tank top. On those occasions I had to go and sort myself out...

I had only known her a few years but Nicole had grown into a stunning looking woman.

She had long brunette hair and a gorgeous full set of natural lips (which I imagined sucking my cock on more than one occasion). She did a lot of athletics in school so had an amazing figure with lovely long legs and a tight ass. Her boobs though.... wow.... I'm personally more of a leg mad but my god... if there was such a thing as the perfect set of boobs she had them. To make matters worse for me I noticed a lot of the time she wasn't wearing a bra....

She spent a lot of time in the garden sunbathing so had a lovely tan. I never noticed any tan lines so I presumed she tanned topless, although I had never witnessed it myself.

That was until I came home early one day....

There was an unexpected power cut in work and it was predicted to be out most of the day so they sent everyone home.

It was a gorgeous day and when I got home I shouted hello to see if anyone was there but didn't get an answer.

I went upstairs to get changed into a pair of shorts before heading outside to chill with a beer and a book.

When I looked out my bedroom window I could see Nicole was already outside.... and she was topless.....

Oh.... my.... god....

What a pair of boobs...

My cock instantly hardened as I watched her lying there on the lounger, her eyes closed, her hands either side.

I pulled my cock out of the shorts I had just put on and started wanking away at it, imagining that Nicole was on her knees in front of me.

Over the last few months I had glimpses of a bit of side boob here and there or the crease of her ass cheeks as she walked by but this was the most I had seen of her.

I closed my eyes picturing what I would love to be doing to her and just before I came I opened my eyes, looking for somewhere to cum when I noticed Nicole had her eyes opened too... and she was looking straight at me.

Fuck....

I quickly dropped down below the window, my impending orgasm all but forgotten about.

What now? Did she see me watching her? It was very sunny so maybe the reflection on the window kept me hidden?

After a couple of minutes, I put my quickly softening cock back in my shorts and decided to head downstairs and act like nothing had happened.

When I walked into the kitchen ready to make an excuse if I needed one, I nearly came in my shorts...

Nicole was in the kitchen... topless.... wearing the tiniest thong of her bikini bottoms with her head back, drinking a bottle of water.

It was like a slow-motion soft porn show. I expected Barry White to start playing somewhere in the background and her to shake her hair in slow motion, water spilling all down her ample cleavage.

Except that didn't happen.

"Oh hi Pete," she said, bringing me out of my trance, "Sorry I didn't hear you come home. Did you get out early today?"

"Ehhh.....ye..... yea.... Yes.... there was.... a... um.... power cut......." I stammered, my eyes not leaving her boobs.

"That's too bad." she replied, not covering herself up or anything. "I was just out enjoying the good weather. Are you coming out?"

"Emmmm.... yea..... yes.... sure..... I'll be coming soon.... I mean.... yes.... I'll be right out..." I replied, my face going beetroot.

She then went back out to the garden, her cute thong covered ass swaying as she walked.

"Bring some snacks when you're coming." she shouted, before I could nip up to the bathroom and wank one off.

I grabbed a couple of packets of crisps and a bottle of beer before heading out.

She was back lying on the sun lounger as I gave her the first choice of crisps.

"You don't mind me sunbathing topless do you?" she asked, looking up at me before briefly looking at the semi in my shorts.

"Ehhh.... no.... not.... at all.... As long as you.... eh.... don't mind... me.... eh... being here?" I replied, sitting down in a chair beside her.

"Well, I'm sure you've seen more than your fair share of boobs." she replied with a wink. "I bet you've played with loads too."

I didn't know how to respond to that. I didn't currently have a girlfriend but I had been with my fair share of women over the last few years.

'So how come you're always single Pete?" she asked, turning on her side to look at me.

That just made her boobs hang perfectly.

"I just never found the right woman I suppose." I replied, trying not to stare. "What about you? I don't remember you being with anyone?"

"I don't want to get tied down if I'm going travelling soon. I'm just happy playing the field at the minute."

"I'm sure you get asked out loads." I replied, the conversation getting a bit more personal than we were used to.

"You would be surprised." she replied, "Not as often as I would like. I don't know why. Maybe men just don't find me attractive."

"What?" I spluttered, spitting out some of the beer I had just swallowed. "You're sexy as hell... The reason you probably don't get asked out a lot is not because you're not attractive... It's because you're stunning and blokes think they would have a snowballs chance in hell with you."

"Do you really think so?" she replied, shyly.

"Hell yes.... You're an eleven out of ten in my book." I replied, before taking another swig of beer.

"Really?" she replied, thinking over what I had said.

The other great quality about Nicole is that she's not one of these girls who know that they are good looking. She thinks she's decent enough but isn't high maintenance enough to be getting her nails done every week and the latest hair styles etc. She is the typical stunning girl next door.

"I'll prove it to you." I replied, getting my phone. I found a great photo of Nicole from mums' birthday party a few weeks ago and blurred out her face so she wasn't recognisable. She was wearing a short tight blue dress, her long tanned legs on show and quite a bit of cleavage. She had her hair curled slightly and was wearing minimal makeup.

I added the doctored photo to the group chat I had with my three best mates. "Just met this girl in work. What do you think?"

"Fuck me... I'd give her one." came the first reply.

"I call dibs on her. She is a STUNNER" came the second.

"I think I'm in love and want her to have my babies." came the third.

I showed Nicole the responses.

"Oh my." she replied, blushing slightly. "Imagine if you had sent them one of me like this?"

"They would cum in their pants." I laughed.

She looked at me for a minute and I couldn't work out what was going on in her mind. "Ok do it. Just don't get my face in it."

"Wha.... ehhh... what?" I stuttered.

"Send them a pic of me like this. I want to see what they say."

"Are you sure?" I asked, not quite believing what she was asking.

"Well, they won't know it's me so yes, it's just a bit of fun. It get's me turned on knowing that guys want to fuck me."

Fuck... this afternoon was going a completely different direction than I had ever imagined.

"Well if you're sure." I replied, standing up to get the best angle.

Nicole lay back and arched her back, lifting up one leg as I snapped away on my phone, making sure her face wasn't in it.

She then put one hand down the front of her thong bikini bottoms and the other on her boob. I didn't know where to look but kept snapping away, thinking that I can wank over these time and time again.

"Do you want one of me from behind?" she asked, turning around and getting on all fours.

That thin bit of material didn't do much to cover anything. In fact, the middle bit was completely lost between her ass cheeks.

She leaned forward as I took snap after snap until she finally asked if I got enough.

She then turned round and her eyes went straight to my crotch.... I had a massive hard on. She couldn't miss it.

"Ohhh.... did I do that to you?" she asked, smiling and biting her bottom lip.

I put my hands over it, trying to hide my embarrassment.

"Oh no don't cover it." she said pushing my hands out of the way. "It looks impressive."

"Emmmmm..... thanks?" I replied, before sitting back down.

She studied my crotch for another few seconds before asking to see the photos.

"Ok." she said, handing me back my phone, "Send some of those to your mates and let's see what they say."

I picked the best three or four before sending them on.

It was only seconds later that my phone pinged.

"Holy shit." replied Greg, "How did you get those? Are you fucking her? You're one lucky bastard."

"Fuck me Pete." replied Steve, "Does she know you're sending those to us? That is one serious piece of ass. I wouldn't mind pounding my cock into that."

"Fuck me... I think I just came in my pants." replied Phil. "Those are some serious boobs. What I wouldn't give to cover those in my cum. Are you seeing this girl? If not, I want to. I know you had a reputation for having the biggest cock in class but it's not all about size. It's what you do with it."

"What did they say?" said Nicole, eager to see the responses.

I handed her the phone and she read all the messages. Her hand slipped down over the front of her bikini bottoms as she read and re-read them.

I could tell she was trying to give herself a quick rub without making it too obvious.

"I think they liked them then." she said after a couple of minutes, blushing slightly before handing me back my phone.

"Told you." I replied, noticing just how hard her nipples had gotten.

"I.... eh.... need to nip inside." she said, getting up, "Do you need anything?"

"Just for you to suck my cock and then fuck me?" I replied... well.... that's what I wanted to reply.

"I'm good thanks." was what I really said. "I'll delete these all off my phone now."

"It's ok..." she replied, heading towards the house, "You can keep them and 'use' them if you want."

Did she mean what I think she meant? She was happy for me to wank over nearly naked photos of her?

About twenty minutes later she came back outside. "That's better." she said, lying back on the lounger.

I just looked at her with my eyebrows raised.

"I was horny...." she moaned, closing her eyes, "It needed sorting."

Ok.... this was new. Talking about masturbating with my step sister.

"Don't try and tell me you don't do it." she replied, when I hadn't said anything. "I saw you up at the window earlier and you arm was moving pretty quickly."

I blushed a deep red, not knowing what to say. She had caught me wanking over her.

"It's ok if you need to sort yourself out too. You can even do it here if you want. I won't look."

Oh my god... what the hell was happening. Was I in a dream?

"Emmm.... Nicole.... I..... eh...."

"It's ok. I know guys do it all the time. It's no big deal." she replied.

"But... eh... you're... emm.... you're..... my.... eh... little... sister." I stuttered.

"I'm not your little sister really. I'm your step sister and I'm not so little anymore. I'm a grown woman. I've seen my fair share of cocks and I've seen guys wanking off before."

Wow... this was all new to me. I thought Nicole was quite innocent. I didn't think she was a virgin but all this talk of watching guys wanking off was not what I thought we would be talking about.

"It doesn't matter to me whether you sort yourself out or not and I'm not offering to suck your cock or anything. I just thought you might need some release."

"I do..." I replied, "I really really do."

"Well then go for it. There won't be anyone home for ages. What do you normally think about when you're having a wank?"

Oh wow... She was going down this route. "It depends on my mood. Sometimes celebrities, sometimes women I know. Sometimes just random people I saw on the way home."

"What about me?" she asked, her eyes still closed.

"What about you?" I replied, unsure what she was asking.

"Do you ever cum thinking about me?" she replied.

"Oh.... eh.... Nicole.... I..... eh......"

"It's ok. You can tell me." she interrupted.

"Ok, sometimes." I sighed.

"So why not wank off now when I'm lying here topless. I won't tell anyone. I won't even peek."

She was right. It was a fantasy moment and I was sure if I didn't, I would regret it for a long long time.

"Ok don't look." I said, getting up and undoing my shorts.

Nicole put her hand over her eyes making sure she couldn't see and I dropped my shorts to the ground, before kicking them to one side, my hard cock bouncing out in front of me.

"Are you doing it?" she asked.

"Just about to start." I replied, taking my cock in my hand.

"Do you want me to talk to you while you do it?" she asked.

"Ehhh...."

"I could talk dirty. I could tell you all about the last time I had sex. Would that get you going?"

"Emmmm.... ok." I replied, starting to slowly wank my cock.

"It was a guy called Steve. I met him in a club last week and we hit it off. He invited me back to his and one thing led to another."

I wanked myself off slightly quicker now thinking about Steve and Nicole and what they got up to.

"You know how it is. There was a lot of kissing, a lot of groping and before long we were both naked. I was on my knees in front of him wanking him off."

That gave me another image to think of, Nicole on her knees in front of me as I wanked harder and harder.

"I asked him did he want me to suck his cock and of course he said yes, so I sucked his cock for a bit, trying to get as much of him in my mouth as I could. After a while I told him I wanted him to fuck me."

I was close... very close....

"I got on all fours in front of him so he could fuck me doggy style. He didn't have a condom but I didn't care. I'm on the pill. He slid his big cock inside me and started fucking me. I really needed it. I hadn't been fucked in a couple of weeks. He held on to my ass and pounded me as hard as he could. His balls were slapping against me and I started to rub my pussy. I wanted to cum so bad."

She wanted to cum so bad? So did I and it wasn't going to be long.

"He then grabbed my hair and pulled my head back. My boobs were just swinging below me. He told me that I needed to hurry up and cum because he was really close. He asked me where I wanted it. I told him he could cum in my pussy or wherever he wanted. That seemed to push him over the edge and I could feel his cock spurt inside me."

Oh fuck.... I felt my own cock tingling as I wanked in front of her, my eyes closed tight, thinking of her getting fucked by some guy she had just met.

"He then pulled his cock out and I turned round so he could cum over my face. I love getting covered in cum. It makes me feel like such a slut."

Oh fuck.... My cock exploded, spurt after spurt of cum flew from its tip as I furiously wanked off in front of my step sister. The thought of her being covered in cum was too much. It was only a couple of days since I had a good wank but there seemed to be no end to my cum today.

Finally it stopped spurting and I opened my eyes.

I hadn't realised, as Nicole was telling her story, I was edging closer and closer to her and she was now covered in my cum. Her stomach, her boobs, her face.... her.... oh god, her eyes were wide open looking at me.

"Shit Nicole." I replied, covering up.... "I'm so sorry, I didn't realise I was so close to you. Fuck.... let me get you some wipes."

I grabbed my shorts and pulled them half way up and with my cum covered cock in hand I rushed into the house to grab some wipes.

I did a quick clean up on myself and pulled my shorts right up before heading back out to Nicole.

When I saw her I stopped dead in my tracks. She was just wiping my cum off with her fingers and then licking them.

She saw me watching and ran her hand down her cum covered stomach and into her bikini bottoms. I could tell from the movement that she had a finger buried inside her pussy.

I stood watching for a couple of minutes before she pulled her hand out and rubbed it all over her stomach and boobs, rubbing in any remaining cum.

I went over and handed her the wipes.

"Thanks." she smiled, licking the tips of her fingers, "Not sure I'll need them now though."

"Sorry Nicole." I replied, "I should never have done that. I was so horny and then you talking about fucking that guy.... Sorry."

"Don't worry about it..." she replied, taking one of the wipes to give her body a quick once over, "I like watching a guy cum. It's hot."

"Really?" I said a bit shocked.

"Yes, really." she replied, "Nice cock by the way."

"Oh.... ehh..... were.... were you not supposed to be keeping your.... eh... eyes closed?" I stuttered.

"I was... but I had to have a quick peak." she replied, "I've seen you in the shower before but not hard."

"What? When?" I asked, shocked.

"One day I came home early. I was only home for a few minutes but you were in the shower and the door was open. I couldn't help myself." she shrugged.

I was shocked that she had seen me naked before now, and now she had seen me wanking my cock before cumming all over her.

"Do you not think this is weird?" I asked.

"Not really. As I said, we're not blood relatives so who cares."

Just then we heard a car pull into the drive.

"Oops" smiled Nicole, getting up, "I suppose I better cover up a bit."

She rushed into the house and pulled on a long t-shirt that had been left in the kitchen, just before the door opened and Derek came home.

"Hi Daddy, how was your day?" she asked.

"It was long and boring." he replied, setting down his briefcase. "What did you get up to?"
