Life of a sex addict

To anyone looking in from the outside John was a normal 19 year old, he was 6 foot tall handsome with an athletic body, but John had a secret. He was addicted to sex, even when he couldn't find someone willing to have sex with him he would masturbate in his room to the wide variety of porn videos he had on his computer.

By any normal standards John had a good sex life, his on/off girlfriend Jenny enjoyed sex almost as much as him and was quite happy to hook up on a regular basis but this was not enough for John. Not only did he need lots of sex the kinkier the better. At this time John didn't have a lot of sexual experience, after all he was only 19 however he already knew he wanted more of it. When he was alone in his bedroom in the house he shared with his Step-mum Susan and Step-sister Sarah he would masturbate and think of what it would be like if he was the star of one of the porn videos he watched.

John's mum had died when he was very young and his Dad; George married Susan, who was quite a bit younger than his Dad. John wasn't sure but he thought Susan is in her early 30's. Sarah was not Susan's biological daughter, she had adopted her when Sarah was about 3 years old when both of Sarah's parents died in a tragic accident. John's dad died just after he turned 18 leaving him the house and enough money that he wouldn't need to work for quite a few years. John was happy for Susan and Sarah to stay in the house as he was glad of the company and they were 2 very attractive women; not that he thought he would stand a chance with either of them. Susan is about 5'10 tall with nice long legs and and long black hair that runs half way down her back; she has nice firm 34D breasts. Sarah was a fiery redhead, her hair was slightly shorter than Susan's but still came well past her shoulders. Susan's breasts were big 36DD and somehow managed to stay nice and perky, her nipples were also quite large and could often be seen poking through the thin low cut tops she wore when about the house.

Today he was watching a threesome sex video featuring a step brother and his step-mum and step-sister, this had always been a fantasy of his given this family situation. he was lying naked on his bed with the video playing on his PC which had a large 32 inch monitor attached which the video was playing on. He had his wireless earphones on. The scene he was watching had the guy having his cock sucked by the step-mum while the step-sister sat on his face.

John was imagining he was the lucky guy and that it was his step-mum Susan sucking his big fat cock which he was slowly working on with his hand. He imagined what it would be like to taste the pussy of his step-sister Sarah, the thought of doing this while his step-mum sucked his cock was almost too much for him to take and he almost came before he had had a chance to enjoy the thought, he slowed down the speed at which he was moving his hand over his now fully erect cock and continued to enjoy watching the video.

It was at this point he glanced in the direction of the bedroom door and saw someone standing there.
