After the rig was parked at the dock, two big men who I had met before smiled wide and asked where my buddy was, as they looked me up and down. They weren't expecting to see me in only panties and shoes. I assured him that sissy one would be here shortly. One of the men opened the back and showed me the load, and I sure was hoping sissy one would be here pronto. But he didn't show up, which had me a bit pissed. But it had to be done, so I grabbed a hand truck and began unloading them. Still no sign of sissy one, and by the time all fifty boxes had been unloaded, I was worn out. One of the men smiled wide and sat in a chair. Obviously, he wanted his payment. I fell to my knees in front of him, as he took out his long cock. "Get it nice and wet, slave!" By the time my saliva had coated the entire length, he turned me around with his strong hands and pushed my face down while yanking my panties to my ankles, with my butt in the air. He was so well lubricated that his swollen cock entered my anus easily, and he fucked me steadily, drawing loud groans from my lips. When he shot his load, his partner yanked me up by the hair and fucked my mouth, I now had cum in both ends. When the last guy was finishing with me, sissy one finally showed up. He whined that he was sorry and would make it up to them next time. I was so worn out, I really didn't give a shit. After the men left I went straight to my cell and took a nap.
