The gates to the youth detention centre banged shut, sixteen year old Steve stood outside the gates smiling, he had just served three months of twelve month sentence and had been released after winning an appeal in the high court, he saw the plain clothes police officer watching him and knew that the police would out to arrest him again. Steve was a well known thug with a bad reputation for being violent and stealing what ever he could, his neighbours had been glad when he was sent to the detention centre knowing they would be safer for awhile at least. Steve headed home when he arrived at the tower block of flats where he lived he saw people look at him and start talking. Steve went to his flat and as expected nobody was at home his mum was an alcoholic so he knew she was out getting drunk, Steve went to his bedroom and stripped then after flexing his muscles went into the shower, he stood under the warm water when the door burst open and Amy his sister who was six years younger than what he was walked in, Amy had just got home from school and not realising that Steve was now home and in the shower went to the bathroom and saw Steve under the shower and when Steve shouted at her to get out Amy went thinking wow he has got a big willie, Steve finished his shower dried and went back to his room, as he past Amy’s room he heard her talking on her phone saying ” it is really big much bigger than your brothers” after dressing Steve went to the kitchen saw Amy and asked her who she had been on the phone to and learnt it was her class mate Cindy who was the sister of his mate Colin who was the same age as he was, when he asked her further questions Amy admitted that her and Cindy had watched Colin in the shower with out him knowing and seen him jerk off. Steve left the flat and went out with a few mates drinking as he was walking home he went behind a tree for a wee and was midstream when he saw Cindy watching him, Cindy walked towards him smiling and said ” that is bigger than my brothers” Steve turned his back and after putting his dick away walked away when he got home Amy smiled at him and said “Cindy told me she saw your dick we both agree it is big and want to see it stiff” Steve ignored her and went to his room. In the morning he was under the shower when Amy walked in and looked straight at his dick, with out warning Steve’s dick went solid standing up at nine inches, Amy said ” yeah it is stiff and massive” Steve rushed out of the bathroom to his bedroom, Steve was putting his joggers on when Amy walked in, Steve had one leg raised as Amy walked in, he lost his balance and fell flat on his back, Amy smiled and quickly sat on Steve’s legs, Steve said ” what you doing get off” Amy said ” playing with this” and got hold of Steve’s dick and started to jerk it, Steve said ” fuck off” Amy carried on jerking Steve’s dick saying no, Steve said ” you cant your my sister” Amy carried on jerking, Steve started to enjoy it and lay back and was soon breathing heavy, Amy carried on jerking Steve and after five minutes felt Steve’s dick thicken then he squirted four spurts of cum, Amy stood up smiled and left the room, Steve lay where he was hardly believing his sister had jerked him off and how good it had been, later that night after being out with hs mates Steve arrived home and saw Amy sat naked at the table as he closed the door Cindy walked into the room also naked, Steve looked at the girls seeing their flat chests and smooth love tubes and went to his bedroom and was standing naked when the two girls walked in, Steve got in his bed which was a large bed the girls got in the bed either side of him Amy threw the duvet back, Cindy said ” get it stiff” Steve looked at Cindy and felt his dick rising and soon he had a full erection Cindy said ” yeah” got hold of Steve’s dick and started jerking him and after five minutes Steve squirted his cum in four spurts and to his surprise Cindy licked it up, when he woke in the morning Cindy had gone home Amy was in the kitchen still naked Steve looked at her and after a couple of minutes had an erection, Amy looked at it and smiled Steve went back to his room and was laying on his bed when Amy walked in and climbed on the bed, Steve started to rub her love tube when Amy lay there groaning Steve inserted his finger and started to masturbate her and soon felt her cum, Amy started to go into Steve’s room every morning leaving happy and when Cindy stopped over night she also left Steve’s room happy, Steve was happy knowing he never had to jerk off again as there was two waiting girls when ever he needed them to deal with his dick.
