Mark was a proud boy, when he had been on holiday in China he had gone into a herbal medicine shop where he had brought a penis developer and pills that gave staying power and now two years after the holiday was happy with the results of his purchases his dick was now eight inches when erect and it took him ages to cum when he jerked off, he was very proud of the size of his dick and had become a flasher, he was not liked because of his flashing but was not worried. It was mid afternoon and Mark was bunking off school and hanging around in the derelict factory when he saw Sara who at sixteen years of age was two years older than what Mark was, Sara had a very bad reputation for being an out of control girl with a very bad temper, most people stayed clear of her, Mark had flashed her a couple of days earlier and had been surprised when she did not shout abuse at him, Mark was sitting on an old table when Sara walked in and looked at him, Mark noticed that a couple of buttons on her blouse were open and he could see quite a bit of her bra covered boobs, Sara smiled and said ” what’s up are you not going to get your cock out” Mark did not make any reply, Sara said ” come on get it out your cock is big it is bigger than what my boy friend has got” Mark smiled stood up and undid his trousers letting his eight inch erection fall out, Sara smiled and said ” that is bigger and fatter than my boyfriends” and then after a short pause took mark by complete surprise by saying ” do you want to use it and fuck me” as she spoke Sara undid the rest of the buttons on her blouse, Mark smiled and said ” yes” Sara said follow me and walked to the steps into the basement, Mark followed her slowly in case he was being set up for a kicking, in the basement Sara went into a room where there was a mattress on the floor and took her blouse right off unzipped her skirt and stepped out of it when it fell to the floor, Mark started to strip, when Sara took her bra off revealing her ample boobs that had erect nipples Mark thought nice and when she slid her panties off Mark could hardly take his eyes off Sara’s smooth hairless love tube but finished stripping and joined Sara on the mattress where she was laying with her legs parted, Mark knelt between Sara’s legs gently massaging her ample boobs and after a few minutes bent forward and slid his throbbing dick into Sara’s love tube, as he pushed it in deep Sara let out a gasp and Mark noticed her eyes went wide, Mark slowly started to thrust in and out of Sara’s love tube pushing in deep with each inward thrust as he did Sara started to breath heavy and groan loudly and after five minutes cried out ” yes yes yes” as she climaxed, Mark continued to push in as deep as he could and after five more minutes felt Sara cum a second time then a third and fourth and not long after the fourth time Mark pulled his dick out of Sara’s love tube and squirted his cum over the floor before laying down beside Sara on the mattress, Sara lay still breathing heavy and after five minutes stood up and started to dress saying ” you fuck good you can fuck me again some time and once dressed she left. Mark hung about in the derelict building for another hour before heading home where he found a note from his mum telling him that she had taken his twelve year old sister to his gran’s and would not be back till the following day. After having a shower Mark was watching telly when there was a knock on the door, when Mark opened it he saw Sara’s sister Jane who was his age and in his class at school, Jane often gave Mark verbal abuse and threw stuff at him, Mark was about to shut the door when Jane said ” fuck me like you fucked my sister” and pulled the zipper on her hoody down showing her naked boobs, Mark let her in and once in the lounge watched as Jane stripped naked and lay on the floor parting her legs, Mark stripped and after a few minutes was thrusting in and out of Jane’s love tube loving the way she groaned and like he had done with her sister made her cum four times before she said ” no more” Mark stopped and after pulling his dick from Jane’s love tube saw the glazed look in her eyes. The next day in school Mark saw July one of Jane’s mates talking to her both girls looked at him and smiled, not long after Mark got a phone call from his mum telling him she would be back about midnight and not long after getting in from school both Jane and July were knocking on his door and not long after both girls were laying naked on his floor with their legs apart, when Mark slid his dick into July’s love tube she cried out and after five minutes of thrusting in and out of her love tube Mark felt her cum and not long after was thrusting in and out of Jane’s love tube and after making her cum moved back to July, over the next hour Mark had made Jane cum four times and not long after making July cum for the fourth time pulled his dick out of her love tube and squirted his cum over her body, both girls left saying they would let him have them more often, later Mark heard his mum return and smiled thinking I do not heed your hand sis I am happy and later the following night when he got a phone message from Sara saying i am at the factory come fuck me he quickly set off to do as requested and when he arrived found Sara and one of her mates waiting for him, both girls were on the mattress already naked with their legs apart, Mark thought sure am happy with that Chinese man he has made me proud of my big dick.
