Sixteen year old Dawn was a well feared out of control thug girl, Dawn was now sitting in the cells of the local magistrate court where she had been on a charge of theft, instead of being sent to a young offenders detention centre the magistrate had offered Dawn the chance to going to a government run medical research centre and be a guinea pig for the testing of drugs or go to the detention centre, Dawn had quickly agreed to go to the research centre and was now waiting to be collected, After half a hour Dawn was collected by two men from the research centre and after a hours drive she was sitting in a very plush office answering questions, after answering the questions Dawn was taken to a changing room where a nurse told her to take off all her street clothes and put on the gown which the nurse handed to Dawn, after Dawn had changed from her clothes into the gown she was taken to a dining room where she was told she could choose from anything on the menu, when Dawn looked at the menu she saw it contained foods that she had only ever dreamed about, after having a good meal Dawn was told to select food from the menu for the next week, Dawn did so thinking to herself this is far better than detention centre. Dawn was then taken to a room where she was told to rest. After a few hours a nurse collected Dawn and took her to a room where she was told she would be given an injection after which she would be left in another room and be monitored, after being given an injection Dawn was taken to a room, on her way she saw Joel a sixteen year old Nigerian boy who lived near where she lived he had his brother Marcus who was two years younger than what she was, Dawn hated the two boys because they were black and often gave them abuse, when Dawn asked the nurse what they were doing here, the nurse explained to her that they were part of the testing team, Dawn was shown into a room where that looked like the type of bedroom that Dawn wished she had, not long after being in the room Marcus and Joel walked in wearing the same type of gown that Dawn was wearing, Dawn curled her lip and snarled at the boys then started to read a magazine, after twenty minutes Dawn started to feel horny, Dawn felt herself getting hornier as the time went by and was soon feeling extremely turned on and well horny and needed relieve, Dawn looked at the two boys and saw that there were tents in their gowns and realised that both boys had hard dicks, after another ten minutes Dawn got up from the chair, Joel spoke to her asking if she needed anything, Dawn did not reply she then saw that Joel was naked and he had a twelve inch erection she looked at Marcus who was also naked with a ten inch erection, both boys were stood looking Dawn and smiling and watched as she started rubbing her boobs through the gown, after watching for a few minutes Joel went to Dawn and ran his hands down Dawn’s back and after not being rejected slid his hands round and ran then over her boobs, before sliding his hands down to Dawns thighs, Dawn started to pull her gown up and after a minute had pulled it right up her body over her head and off and was now standing naked, Joel started to rub Dawns boobs while Marcus slid his hand between her legs and started rubbing her love tube, Dawn pulled away from the two boys and went to the bed lay down on it parted her legs and said ” fuck me” Joel went over climbed up on to the bed and knelt between Dawns open legs bent forward and slid his twelve inch dick into Dawn’s very wet love tube and as he did Dawn cried out in pleasure, Joel started to slowly thrust in and out of Dawns love tube while his brother Marcus sucked and licked Dawns very erect nipples, Dawn was soon groaning real loud as Joel increased the speed of his thrusting and after a few minutes he felt Dawn cum as she did Dawn cried out ” yes oh yes” after a minute Joel pulled his dick out of Dawn’s love tube and climbed down off the bed, Marcus stopped licking Dawns nipples went round to the other end of the bed and climbed on to it and knelt between Dawns still open legs and after rubbing Dawns love tube for a couple of minutes bent forward and slid his throbbing dick into Dawns love tube pushing in as deep as he could and as he did Dawn again cried out with pleasure, Marcus started thrust in and out of the older white girls love tube pushing in as deep as could and loved to hear the way that Dawn was moaning in pleasure, Marcus thrust on and after five minutes Dawn climaxed for a second time, Marcus loved the feeling of Dawn cumming, after a minute Marcus pulled his dick out of Dawn’s love tube and climbed down off the bed and gave his brother a high five as he climbed up onto the bed, after a hour both Marcus and Joel had had made Dawn cum multiple times and Dawn was starting to relax and get back to normal as the drug wore off, in the observation room the nurses were making notes and had noted that Dawn had climaxed ten times and was now sleeping. Marcus and Joel were taking a shower, Marcus said to Joel never thought that we would get to fuck that racist bitch, Joel replied ” yeah and we get paid for it. The next day Joel and Marcus were both sitting in the testing room when the door opened and in walked July who was Dawns sister and was two years younger than Dawn, July was wearing the same type of gown as to what Dawn had been wearing and was at the testing centre under the same conditions as what her elder sister was, the two boys looked at each other and smiled, after half a hour Marcus was sliding his erection into July’s love tube as July was saying ” fuck me fuck me” Dawn was laying on her back in another room moaning and groaning as Tina a lesbian girl who was July’s age wriggled her tongue around inside the love tube of the straight Dawn, Tina’s best friend who was also the sister of Joel and Marcus sat watching as she waited for her turn thinking I like this part time job it’s good.
