It all started after I broke up with my girlfriend Steph. It was an awkward split and, as she happened to own the flat we were both living in, I had to find somewhere to live.
Realistically I only had two choices, either to go and stay at my parents who lived out in the country or persuade my sister to let me stay with her in her flat in town. To me the best option was the latter, I am a townie and the thought of having to go out to that sleepy village that my parents lived did not appeal one bit, besides there was also the question of me getting to work every day.
My sister, Susie, is a couple of years younger than me, 23 to be precise and fiercely independent and it took some smooth talking to allow her to let me stay.
It was my first morning there and I was trying to sort out my worldly goods especially the bits that needed washing - which was most of it. Steph had literally thrown me out there and then, followed by my clothes which landed in a nice mud filled puddle. As all I had to wear at the minute was my boxer shorts I decided that my first task of the day was to get some clothes clean. I went to use the washing machine but could not find the powder to put in it!
A little frustrated I went straight to Susie's room to ask her where she kept her soap powder. All thought of that vanished as soon as I opened the door.
My little sister was naked on her bed, her hand on a vibrator which was, most definitely, firmly inside her.
She heard me come in but did not seem to be startled, she calmly removed the vibrator, turned it off and turned toward me, making no effort to cover herself,
"Sam, would you please learn to fucking knock before you waltz in to my room."
"Sorry," I muttered almost incoherently, I should have turned and left right then but my eyes were transfixed and my feet felt like they were bolted to the floor.
"Sam," said Susie, in a quite stern voice, "why are you gawping like that -- are you trying to convince me you've never seen a naked woman before?"
Now there's the question isn't it -- yes I have seen naked women but since when did sisters count as women? I guess you don't really look at them in that sort of way. Right now I was looking at a woman. Susie had a gorgeous body her long dark hair was laying across a beautiful smooth neck. Her breasts were not too big but full and firm, the nipples still slightly erect from where she had been stimulating herself.
"Erm Sam," she said bringing me out of reverie, "Oh I get it, it's this isn't it" and she waved the vibrator at me. "Next you'll be telling me you've never masturbated yourself!"
She gave me a look up and down.
"In fact you probably need to masturbate right now". My face must have gone bright red as I realised that my cock had started to get hard beneath my boxer shorts, suddenly my sister was a sexual object -- a fact that was sending my mind wild.
Susie smiled sweetly, "Look Sam, I need to finish what I started, now you can stay and watch if you want as long as you get those shorts off and do yourself at the same time. Or you can get out right now."
With that she lay on her back and started the vibrator again and started to rub against her pussy, I just froze for a moment until she looked over toward me and raised her eyebrow. Without any real thought going through my head I dropped my shorts and moved over to sit on the end of her bed.
I watched as Susie became engrossed in pleasuring herself, the vibrator buzzing against her clit while she fondled her gorgeous breast with the other hand, I moved around putting my feet on the bed so I could watch her better.
My cock was fully hard now but I only stoked light and slow, any harder and I would have shot my load there and then.
Susie looked over at me, or rather my cock, smiling she moved her sex toy from rubbing herself and thrust it deep inside that very wet hole, she began to pant louder and louder as she bought herself closer to climax.
All rational thought went out of my head and I started to wank hard, pumping my cock at the sight of my naked sister's body as it glistened with sweat, her nipples erect, her hips bearing down hard on her vibrator. It was too much for me and I spewed a huge jet of cum from my member, Susie saw it and it must have excited her as she screamed out in orgasm.
We both remained where we were for a moment or two catching our breath, brother and sister naked together. Then Susie sat up and became very matter of fact.
"Right I need to jump in the shower then get ready to meet some friends for lunch and shopping. Oh by the way what did you want?"
"Washing Powder" I replied somewhat lamely.
"It's in the cupboard by the kitchen door" She replied before leaving the room.
I was still sitting on her bed naked when she returned from having a shower, she picked up my boxers from the floor and threw them at me.
"Come on Sam, go and get your washing done, I want to get ready."
With that I pulled my boxers on and left the room. Just a little while latter Susie called out "See you later" and I heard the front door close shut.
It seemed my sister was quite happy to carry on as if nothing had happened. It was a different matter with me, my mind was reeling. I felt guilty -- how could my and my sister do such a thing. I felt shocked -- why would Susie do that, why would she just flaunt her body in front of me like that.
