When I was 16 I dropped out of school and started working I was selling on a market and I was pretty good at it and so was soon making real good money. I have an older sister who was 20 but she was a waster who used drugs pretty hard and was always looking for money.
One Sunday I was home surfing a bit of porn when she called round, both my parents were out so she was pissed as she had come to try to get money off them, in desperation she started asking me for money so I told her to f**k off and earn some if she needed money. It was embarrasing she was on her knees begging for money freom her 16 year old brother, I almost felt sorry for her, she noticed the porn on my Laptop ans offered me the services the grls in the film were doing, I was watching a pretty heavy s&m movie at the time as i have always got off dominating girls. I laughed at her and said she wouldnt last 5 minutes of that shit not to mention me being her brother.
She pulled off her top showing me her tits (which were pretty good) then stripped off completely still grovelling on the floor and said Master I will be your slave and do anything for $25.
I have to admit my cock was rock hard and so I said OK $25 buys me 2 hours and you can expect to be hurt and abused if you cry stop at any time you get nothing. She nodded her head and said yes master anything. I stood in front of her and ordered her to undress me which she did, I pushed her up against the wall and rammed my cock into her c**t looking her right in the eye as I did it, she tried to pull away and so I said you want bto stop?? She just looked at me and said no I need the money badly but you are not wearing a condom, I thrust into her again and whispered i am going to cum in your c**t sister dear and your ass and your sweet little mouth so if you dont like it we can stop now. She just said yes master I know I am yours.
Well over the next 2 hours I kept my word and did the whore in c**t ass and mouth as well as caning het and doing nipple and pussy lip torture, on the last fuck deep in her c**t I felt her boddy tremble with orgasm and her eyes filled with tears of shame.
When I was done I peeled of $25 and threw it down on her naked c**t laughing.
There have been plenty of other occasions since then and maybe I will tell you about them soon.
