All the girls japanese went to the table with the plastic boxes and picked one up, presumably the one with their name on it, then went to stand at a chair or table or other place where they presumably had to test their item. The lab coats then went to each girl in turn, got them into the required position, switched whatever on then inserted them into the girl’s pussy. At the sybians the girl just impaled themselves and waited for a lab coat to switch them on. The girl on the treadmill had a remote controlled vibe put inside her then she started walking on the treadmill. Seconds later her body jerked but she kept on walking. Mr Tay took me over to the one place that was vacant, one of the mattresses, and told me to lie down. As I got down I was feeling confident that I could cope with anything that they gave me. A lab coat came over to me and indicated that I should spread my legs wider than they already were. Picking up a tube of lube, he looked at my pussy then put the tube back in his pocket. I’d dried my pussy when I’d gone to the toilet a few minutes before but it was again soaking by the time that I lay down. The lab coat got the brown paper covered box out of the plastic box and un-wrapped a metal egg with a wire coming out of it. On the other end of the wire was a little black control box. That had another wire coming out of it that went to plug that he pushed into a socket on the wall. I wondered why the metal egg couldn’t run on battery power. As the lab coat eased the metal egg up my vagina I thought that it was going to be just like have one of my vibrators purring away inside me. It was, well for the first couple of minutes. Then I got the shock of my life; literally. I screamed, not knowing what had happened, but when I got over the shock I realised that I’d had a shock; an electric shock; inside my pussy. My pussy reacted by getting wetter and raising my AF. The vibrations continued and after another couple of minutes I got another electric shock and my AF went up another notch. Ten minutes later, a fourth electric shock took me over the edge and my body arched up then shook all over; my body expressing itself in a stream of loud expletives. The process repeated itself over and over, the gaps between my orgasms got shorter and shorter as the vibrations alone made me cum until I was almost having one long continuous orgasm. I was sure that I was going to back-out; but I didn’t.The vibrations finally stopped and I just lay there, covered in sweat and feeling totally knackered. After a few minutes a lab coat came over to me and I gasped and jerked as he slowly pulled the metal egg out of me. I asian looked round and saw lots of other knackered looking girls; the American fathered girl on a sybian with her head hanging forward. I guessed that they too had been pleasured / tortured for the full hour as well. As my eyes reached the door I saw Mr Chang stood with Mr Tay; both were staring at me, smiling and talking. I got onto my knees, not sure that my legs could hold me up. After a couple of minutes Mr Chang came over and held a hand out. I gripped it and pulled myself to my feet. “You have done well Tanya; Mr Tay is pleased; apparently our Chinese girls black-out after about 20 minutes. As I walked MILF over to Mr Tay I saw one of the lab coats putting the shocking vibrator in japan to the plastic box with my name on it. “Thank you Tanya,” Mr Tay said, “that was most interesting. We will repeat that for the next few days and see how the device stands mature up to its continued use.” So pink. He quickly got the rest of his clothes japan together and got the asian hell out of there. She started playing with it like it was a toy. “There’s just one problem.” She hugged me goodbye and there dad MILF picked her up. But to be honest, it turned me on seeing him being rough with her. Her nails left trails in the table as he hammered her like mad. I leaned over and kissed Amy on her lips and lifted myself to get out of bed. I don’t think there’s enough guilt left in my dearest niece to expel the Sentient, and I’m wary at best of Julia’s tactic of forcing the bitch out.” She was being pushed forward and pulled back japanese with her nipples kissing Lola’s.She came after a few minutes and collapsed on Lola, mature panting in her ear. In the distance, I saw twin pillars of melted iron.
