It had been a long hard day and finally I was able to put my feet up and was resting when I heard the door slam and the car wheels screech, I was completely clueless about what had happened but when I got up, I had notice my parents and their car had gone. I was worried and quickly shut and locked the door before heading upstairs to check on my sister. She was slightly older than me and was laying on her front in the bedroom, I slowly approached her with a gentle smile and sat down next to her on the best. It was an awkward silence but I explained how bored she was and she suggested something. Something strange and extremely odd and I felt paranoid and literally dirty about the suggestion she had made.
As she was in the comfort of her own room, she was only wearing a tank top and some short shorts but as she knelt up, despite being my sister, it was the first time, I really acknowledged and appreciated her well developed body. That was of course helped by the fact that she was pressing her breasts together in a seductive manner. She always had a minimum amount of make up on and she had bright ruby lips which was a norm now and she also had a minimalistic amount of make up on which wasn’t a bad thing at all. She fluttered her eyelids and leaned in, I didn’t know what had caused this influx of erotic behaviour and attractiveness to spontaneously spring up for one of her own flesh and blood but she kissed me. Time seemed to slow down and it all seemed so wrong but felt so right! I kissed her back which seemed to surprise her as her eyes widened with disbelief rather than disgust.
I was lost in the moment as she pushed me on to my back on the bed, she slowly unbuttoned my shirt and carefully removed it before running her fingers down my toned chest, followed quickly by her tongue which rested at my peck and started licking it rapidly, I still felt uncomfortable but she tried to change that by placing my hands on her toned bum. I gave it a cheeky squeeze, she giggled and wanted more. I got more into it and began spanking her harder and harder and she moved further and further down my body. She had reached my toned stomach and I was pretty sure that her bum cheeks were red raw. She slowly undid the belt and pulled it off before undoing each and every button of my jeans before slowly pulling them down to my ankles. She hesitated and took a long deep breath before looking up at me and licking her lips. She ripped the boxers off, out of anticipation and braced herself for the job. She started by using both her hands and running them both up and down the large shaft, taking special consideration to feel the throbbing veins before focusing on the head, she started by slowly sucking on the foreskin before deciding to pull it down, she did it quite roughly and set to work by experimenting to see how much of my cock she could fit in my mouth, at this point, we were at the point of no return and I was being pleasured to well to care about it being my sister. She was nibbling on the sensitive head whilst massaging my testicles and tugging continuously on the shaft. It was expertly done and I was more than pleased, I wasn’t the most experience and I felt a twinge of semen rushing into my head, swelling it up, that was the cue for her to move on and she did so as she sat back and thought of the next way to pleasure me.
I did keep looking over at the clock, I was worried any moment now, my parents could walk in and see both their children pleasuring each other sexually and I wanted to avoid that awkward situation. She straddled me and lost her shorts and underwear in one swift movement. Now I could see the shaved pussy which had been expertly managed as there was no rash or no signs of any interference as it slid down on top of my throbbing lubricated penis. She slid down and she was extremely tight from how it felt, it must have been her third or fourth time, she’d have had sex. I was careful and as she began to bounce, I began to lightly thrust, helping her as I kept the momentum going. Something was missing and I realised as I lifted the tank top up and revealed her petite but perky breasts from beneath. They rose and fell as did the rest of her body and I enjoyed it more as my cock began to bulge even more, she smirked and was enjoying it as much as I was but we both knew that this wasn’t a regular occurrence, in fact it shouldn’t have been an occurrence at all but I’d been seduced by her utter innocence. I felt responsible but she had done all the running, she had suggested the idea and she was the one to make the first move. Whilst I had this internal debate inside my mind, I had lost the energy and enthusiasm that I partially had for this sexual act as she began to tighten up and contraction began, soon she was almost certain to shower my cock in a flood of juices as many girls had done before but never before had it been so wrong for me to enjoy this moment and never before had I have to suffer the repercussions of my actions. She was so enticing but I wasn’t drawn in a moral battle not to enjoy myself but I couldn’t help myself as I let out an almighty sigh and soon followed was a large load of the murky coloured white paste which filled her up nicely.
As we finished, I saw lights shining on the window, I panicked and ran out of her room into mine where I quickly got dressed and pretended to be doing some work. My parents stumbled in drunk and unaware of the activities their children had been getting up to whilst they were away.
