To be continued... Tracey stood tits outside the gleaming white building looking at the large sign which read, Eastfield Medical Science Centre and wondered again why she was there. It was her boyfriend Steve, that was why she was there. It was him who had seen the ad in the local paper asking for volunteers to test a new breast enhancement drug. As far as Tracey was concerned she was more than happy with the current size of her breasts thank you very much, she was the proud owner of a set of DD boobs, but everybody knew that as far as men were concerned there was no such thing as too big. Apparently Titalin was a drug designed to increase the milk yield in dairy cattle and it had been a great success in the cows increasing their yield by 150%. Someone had noticed that the size of their udders had increased exponentially and had come up with the idea this might be a good drug to give to human females. Nobody knew if it would make them produce milk but if it increased the size of their breasts that was a good enough reason to try it, and so human trials had been started. The first set of tests hadn't gone that well, the drug was too powerful for humans, it had been designed for cattle after all. They used fifty girls for small the first set of tests and they all ended up with balloon size breasts that leaked milk constantly. They also ended up as brain damaged as you could get, the drug rotting their brains. The press heard about all of this and treated the story as a funny aside, picturing some of the girls deepthroat cock with their freakishly huge breasts and drooling from the mouth with a blank expression. One newspaper printed a picture of six naked girls in sitting in a cow stall with the heading, The Perfect Girl! All of this gave Tracey natural cause for oral concern but the advert her boyfriend saw stated that the trial was going to use a new version of the drug which had been reduced in strength. That still didn't exactly placate her too much but her boyfriend was not the type of man a girl argued with, a few black eyes had taught her that! It didn't even make her feel any better when she'd heard that the trial was to use twelve girls in total, six slaves and six free girls. She was a free girl and glad of it, female slavery had been legalised a year before and was still in its infancy. She had sparkly blond hair that dropped down just below her shoulders. She reached down under the sink and pulled out a fifth of vodka and poured it into the juice bottle until it was filled. Towels wrapped around them, they sat on the bed and caught up on life for a bit, talking like regular siblings as they ate and drank. He's a good lover and I’m sure she would enjoy it. Now he whispered in the girl-captive’s ear. “Can I try that egg before you use it? So to play the moment and create some tits sexual tension I told them I needed to drink lots of water, which I did very slowly. "Oh fuck," he said. Mom moaned in my mouth as my fingers explored her dripping wet sex. In and out, in and out, it pounded its throbbing cock like a machine into the girl’s young pussy. "True, true. I couldn’t wait for them too be home. I did jump a bit as the whip was cracked in the air, but I wasn’t really prepared for the pain as the first stroke landed. Master had Asphyxiation is imminent." I was soo excited. I was going to have sex with my father. "I'm sorry Derrick, Thaddeus refuses to come aboard. I oral was breathing heavy, my mouth was dry, and I shot a rope of cum farther up my stomach than deepthroat I had, in a long while. Doesn't take watching porn to get me horny.” Ashley still had a breast exposed and Laurel was still topless, though she had turned onto her left side. Even though Elena was gone to small Ternianas the whole afternoon, I still hadn’t seen him. So was the dog, he laid down watching me. They want my help, but they only want it on their cock terms, putting my people in harm's way.
