Sex is a time bomb that lures partners into the radius of its explosion and leaves no chance to escape. The woman lies on her belly along the sofa, placing her hands under the head. Her legs are slightly bent at the knees, her hips are spread apart, and buttocks are raised. The man positions himself above his lover, resting his feet against the armrest. He supports himself by the palm of his outstretched arm placed on the opposite armrest. He puts the other palms on the female partner’s back and enters her from above.
