Shortly after my 18th birthday my Father got remarried to Kate. Kate was a 33-year-old (6 years younger than my Father) health club employee where she was an instructor and taught swimming and aerobics. She was also head coach in the local tennis club. All this sporting activity meant that she had a very athletic body with long legs a firm and well round ass and a large bust round a C cup. She had shoulder length blonde hair and green eyes, My Father met her at one of her swimming classes and they fell in love almost on sight. I really fancied Kate but never told Da or Kate, as she was a lovely person and I didn’t want her to feel strange.
Kate also had a 16 year old daughter named Emma who was almost a exact duplicate of her Mother except her skin was darker as her Father was from Egypt (He ran out on Kate and Emma when Emma was only 3) and her bust wasn’t quite as big, although it was still in development and fairly sizeable anyway.
One day (about a year into the marriage) I came home from work and noticed that Da’s car was gone I found this strange as he only drove if he was going far and walked cycled and ran everywhere else.
When I got in to he house there was a note on the fridge which read:
John(Me) and Emma
Sorry but Me and Kate had to go out of town suddenly, we’ll be gone for two nights. We left you some money to get dinner and that. We’ll give you a call later. Take care
Da
I headed up stairs to my room to change out of my work uniform, as I reached the top of the stairs I could hear the Shower on, “Emma must be home” I thought to myself before I went into my room and changed into a pair of shorts and a T-shirt. Then just as I left my room the bathroom door opened and out step my 16 year old Step-Sis with only a pink towel warped around her almost perfectly curved body. The towel just about cover up what it was suppose to
Emma: Oh Hi John I didn’t hear you come in. Did you see the note on the fridge door?
Me: Yeah I didn’t even know they were going anywhere what time did they leave?
Emma Oh just over an hour ago, it looks like were home alone tonight then.
With that she gave a little smile and continued down the hall and into her room. I went downstairs but it was kind of cold so I ran upstairs to get a sweater. I noticed that Kate’s and Da’s bedroom door was slightly opened. “That was closed when I was up last,” I thought to myself. I approached the door but as I did I noticed Emma in the mirror she had her back turned to it and was leaning over the bed, she still was wearing only the towel and I could see the crack of her ass as she bent over the bed. I moved a bit closer and could see that she had several different pairs of Lingerie (that must have belonged to Kate) lying on the bed and she seemed to be choosing between them. After a few minutes she picked up a black lacy bra with a matching black G-string and smiled to herself. She let the towel hit the ground and as she did so my cock sprang out to its full length of just over 9 inches. She admired herself in the mirror as I began rubbing my stiff bulge though my shorts. She then pulled the g-string up over her long silky smooth legs and did up the clasp at the back of the bra. Again she turned to the mirror and started admiring herself. Suddenly her hand slipped down her tight little tummy with a belly button ring and under the thin strip of material, she began gently rubbing her clit and fingering her self. I couldn’t believe I was witnessing this. Just then as I began to get a good motion going on my swollen cock the phone rang, I quickly stuffed it back into my shorts and ran downstairs to answer the phone. It was my Da
Da: Hi, John is that you we just arrived here and Kate asleep. Are you and Emma Ok?
Me: Aye, were grand, I’m just back half an hour and was about to order a take away.
Da: Sounds nice, Listen the money in this phone about to run out, so I’ll have to go, give Emma our love and I’ll ring you tomorrow again sometime. Bye
Me: Bye Da
Just as I hung up the phone Emma was coming down the stairs, she was now dressed in a pair of tight black jeans and a low cut red top the also left her sexy little tummy out.
Me: I didn’t know you had a belly button ring Emma
Emma: Yeah I got it last week Ma doesn’t know yet, you won’t tell will you?
Me: Naw, I think its cool looking.
Emma: (Blushing) Thanks and sexy too don’t you think?
“Not as sexy as what I just witnessed” I thought to myself.
Me: I was about to order a take away, would like me to get you something?
Emma: Yeah thanks I would love a curry, and seeing your taking of dinner I’ll fix us some desert.
About 10 minutes later, there was a knock at the front door. It was the food, I paid the delivery boy and Emma and I sat down in front of the TV and tucked into the spicy dish.
Emma: Jesus but that was lovely, right its desert time.
She disappeared into the kitchen and came back out with two bowls of ice cream chocolate mouse and strawberry sauce. As she approached the sofa she tripped and fell on top of the deserts.
Me: Shit is you ok?
Emma: Yeah I’m grand but the deserts are ruined, my fucking top is stained and all my others are in the wash.
She pulled of the red top to reveal the black lacy bra, which I had seen her choose a little earlier.
A bulge began to form in my shorts, which Emma pretended not to notice but I caught her glancing at it.
Emma: What am I gonna do I’ve no tops clean tops left and mum has all hers away. I can hardly go about like this all night can I?
Me: Uhhh! No sure you can borrow something of mine.
Emma: Thanks
She ran up stairs and came back down wearing and old football top of mine that I hadn’t worn since I was 14, but it fit her figure like a glove emphasising all her curves.
Emma: I found this top at the back of your wardrobe and I never seen you wearing it before.
Me: Yeah I haven’t worn it in almost five years you can keep it if you want.
Emma: Thanks, I think it’s really cool.
She sat next to me on this sofa and lay her head on my thigh, her head centimetres away from the growing bulge in my shorts.
Emma: What else is on?
I flicked though the 150 channels of cable.
Me: Not an awful lot.
Emma. Can I watch a video then.
Me : Ok, what you wanna watch?
Emma: I’ll put on the video of Mary’s (Kate’s sister and Emma Aunt) weeding that your Da took last month.
She stuck the video in and it started with the ceremony in the church.
Me: Jesus Mary looks just like you and Kate.
Emma: Of course she looks like mum their identical twins.
Me: I didn’t even even know Kate was a twin let alone an identical twin.
After about 10 minutes the video cut to the reception and Mary and her groom Mark cutting the cake and some dancing.
Suddenly the tape went all fuzzy and came clear again. It showed Kate dusting in the upstairs bedroom.
Emma: What the hell is this?
Me: I’m fucked if I know.
Then suddenly my Da came running into the room grabbed the duster out of my Mums hand and pushed her on to the bed. He grasped her skirt and yanked it off before pulling his top off. Next he pulled down his trousers and ripped off Kate’s top. She was wearing the same black bra and g-string that Emma was presently wearing I recognised them straight away, but could see Emma lifting up the football top and double-checking. My Da pulled off his boxers and revealed his 9-inch fully erect cock and balls. Emma began to stare at the screen. Next he undid the clasps on Kate’s bra and her large tits spilled out revealing her pointy hard nipples. Kate pulled off her g-string stuck her mouth around my Da’s cock and began to finger herself.
Both Emma and I were fixed on the screen each taking a keen interest in the others parent was doing. Emma casually slid her hand under her jeans and began rubbing her self as her mother sucked on my da’s cock, my cock was getting bigger by the second as both the our parents entered into a 69.
Suddenly Emma’s free hand took a firm grasp of my now fully erect cock and began wanking me.
Emma: Well aren’t you gonna return the favour? I hope so, cause I can feel that you have certainly inherited something from your Da.
She unbuttoned her jeans and let the fall to the floor, before sliding down the black g-string and sitting on my face. I began to lick her out.. she bent down unzipped my fly and started to suck my cock. I could hardly believe that I was in the 69 position with my little step sister and not 5 minutes ago we were watching our parents in the same position.
After about 15 mins I shot my load all over Emma’s face which she readily licked up. She pulled of my pants completely and my boxers, then pulled the football top up over her head and removed her bra letting it fall in my lap. I pulled my sweater and T-shirt off and Emma began sucking my nipples and kissing my pecks.
It wasn’t long before my cock arose again from its slumber a pointed straight up.
Emma: Do me up the arse, I want some anal action now. So stick your huge cock up my little tight arse big bro.
I did so immediately and as my rhythm intensified she began to moan and yell in pleasure, II fucked my young step-sis up the arse as hard as I could for the next 20 mins until she gave a large moan of pleasure and her juices ran down her leg.
I collsaped of the sofa but my cock was still fully erect.
Emma: I’m not finished with my new to yet so give it back.
She grabbed my cock and sat her shaven pussy on top of it and began sliding up and down it, her speed intensifying every so often. I grabbed her tits and began to play with her nipples.
Me: If your using my stuff to play with, I’m gonna have my fun with these that belong to you.
I begun to lick her nipples with the tip of my tounge, Emma began to moan softly.
Emma: Ummmmmm, ohhhhhhhhh. Yaehhhhh that’s so good It’s the best I’ve ever felt. Please don’t stop my darling bother don’t ever stop.
After another 15 minutes I felt the pressure build up in my ball bag.
Me Shit I’m gonna cum!
Emma: Me too quick.
We got back into the 69 position and took each others bodily juices in our mouths and swallowed.
With that we collasped on the sofa together.
Emma.. That was fun, it’s the most fun I’ve ever had with you, we should certainly do this again.
Me:Yeah of course.
