The crazy scientist had an ordinary day. He was walking around his abandoned house, which is far from the city. He chose this place not by chance: here no one will hear screams. He drank tea, read a book, and he wanted to do new research. Then he went to his bedroom, put on his work robe, and opened the safe. It contained basic necessities: a stethoscope and glasses for experiments. You never know what might splash into his eye. Then he went to another room, in which there were two chests. When he knocked on them, screams and moans were heard from there. He used his favorite rhyme to choose which chest to open. The choice fell on the right chest. When he opened it, there was a girl lying there. Her mouth and hands were taped, she tried to scream, but she couldn’t do it well. The scientist took his slave out of the chest and threw her on the bed. He needed to take his notebook. The slave didn’t even try to escape, he knew that it would end badly for her. Then the scientist took her to the table and tied her with ropes. He then placed her on the table and took out his vibrator. At first he simply rested it against his slave’s clitoris, and then fixed it so that his hands could be free. Then he began to measure her pulse and listen to different parts of her body with a stethoscope. He wrote down all the testimony in his notebook. The girl lay there for a very long time, she experienced several orgasms and was all wet, and the vibrator sent waves through her pussy. When the experiment was finished, the professor put his slave back into the chest. She was lucky, now she can rest here peacefully. You must see this.
