Your inmate is waiting before you, shackled, waiting for instructions. You tell her to bend forward, on all fours. She complies. You give her a heavy steel plug. She seems to know what its for, but she's never used one before! Your inmate complies, inserting the plug and awaiting further instruction. You start fucking your inmate, eventually turning her over on her back. Before long, she realizes what you want. You want to cum in her pussy!
