Anal

The word "ANAL" is projected on the large screen behind the host and the crowd cheers. Black Widow begins to regain consciousness. "I'm sure you've worked out by now competitors, that our winner must fuck the loser in the ass!" The host bellows.
"What if we refuse?" Black Widow shouts back, half knowing the answer.
"Then you will be killed and your planet will be destroyed!" A picture of Earth flashes up on the screen. Knowing what she has to do to save the world Black Widow begins to unzip her suit. "Okay, lets get this over with."
"You really want to go through with this?" You ask her.
"I've done worse to save fewer lives." She says as she steps out of her suit, leaving her in matching black lacy underwear. She quickly removes the bra, then the panties. She turns away from you and gets down on all fours in the dirt. She looks back over her shoulder at you. "Just go easy on me alright?"
