My sister Lauren in the bathroom

My sister Lauren in the bathroom

I love the internet. As a 15 year old boy I have had all the talks with my Dad about sex education and the facts of the birds and the bees. He’s a pretty cool guy and easy to talk to so it was quite painless when we had ‘the chat’! Saying that, my Mum is cool too and as sex has never really been a subject that they have been shy talking about it is something that we have grown up understanding more than some of my friends. But the internet has allowed us to have easier access to sex in every form and made it easier to check out porn than when my Dad was younger having to rely on sneaking porno mags into his room or watching old video tapes he managed to get hold of.

Since I can remember, my sister and me have been comfortable seeing each other and our parents in various states of undress and up to the ages of around 11 we thought nothing of walking round the house nude. But puberty started to take its course and we somehow just began to cover up a little and close the bathroom door more often to have our privacy.

With my sister being a couple of years older than me I always wondered why my mates would come round to play when she was about, but as I grew and started to notice girls more it finally dawned on me that she was actually pretty fit. Gorgeous in fact with a killer body and one of the nicest asses I had ever seen. No surprise really as my Mum was a gorgeous woman with my mates calling her a MILF!

We seemed to be an odd family though as the four of us still lived together and my parents still seemed to love each other as I had never got any indication that they were unhappy. I even got on with my sister! We had the usual arguments over who should have control of the TV or one taking too long in the bathroom but other than that we got on well. So many of my friends had issues with parents who were either split up or brothers and sisters they seemed to fight with all the time. I wouldn’t say we were the perfect family, but we must have seemed like that from the outside.

But I didn’t feel too perfect when all of a sudden I started fancying my sister. I knew my mates would joke around and share amongst themselves what they would like to do to her, or what they would like her to do to them but I had always deflected those thoughts as she was ‘my sister’! But as a growing lad my hormones were racing and I started to notice her a little more and more as she continued to parade around the house in skimpy clothes. She would think nothing of coming down after her evening shower in her nightshirt and a pair of girlie boxers and wander around the house with her bum cheeks just visible below the material and I would find myself watching her more. The unfortunate thing was that my body also started to respond and so I would have to be very careful where I sat to make sure that my raging hard on wasn’t obvious to everyone!

I think my Mum started to notice though as she would occasionally question Lauren about her lack of clothes and suggest she perhaps cover up a little more. Lauren would just laugh it off asking me or my Dad if we minded when we were about, obviously getting a ‘no’ in reply. But I even noticed my Dad on more than one occasion checking her out so I knew it was becoming an issue, although he had the adult version to sleep with at the end of the day. I was even sure that once it had been brought to her attention Lauren would then do it more on purpose by wandering around in next to nothing just to tease me. She wasn’t blind and could easily see that I had matured myself over the last few months and seemed to enjoy the reaction she got from me when she walked around near naked.

It was a Friday night when it got serious.
