Heat and Rut
It was telling my body what to do.
My legs began to shake. Against my own mind, they started to move apart. I tried to fight it. I tried to clamp them shut but the pressure in my head was too strong. My legs opened just a little, then a little more. Until my feet were apart on the dirt floor.
He smiled. It was a cruel smile. "Good," he said. "Now hold that position."
He stepped back. His eyes were locked on my face, I was standing there with my legs open like a shameful thing. I could feel the cool air between my thighs, my face was hot with humiliation.
