A woman in a Soviet school uniform with a huge vagina, wearing black rubber stockings and high-heeled shoes. Her uniform consists of a simple dress, a feminine navy blue or black color, with a white collar and cuffs. She can wear high heels or sit on the floor in an old satin skirt. The walls are covered in mucus and the floor is made of thick bricks. There may be a school background, many pictures, and text that describes the experiment as being conducted by skilled technicians who are experts in their field. The woman's body is stretched out by hooks from which she hangs from the ceiling. She has large breasts that hang down below her waist and are covered in dust particles from the air. The woman's vagina is dilated and swollen with thick hoses inserted into it for sexual pleasure purposes. The lab contains many objects such as sex machines, dildos, harnesses, restraints, pumps for vaginal lubrication or lubricant injection devices used to stimulate sexual arousal during experimentation on women's bodies. The laboratory is full of machines that generate intense vibrations to stimulate the women's genitals while they are restrained by straps or chains attached to hooks fixed to the walls or ceiling of their enclosures.
