"Her career as a professional fighter was not going very well. So she got a job at an underground fight club tat paid big dollars weather she wins or looses. The men who come to challenge the female fighters are mostly not professional fighters but are often much bigger than her. She has had ten fights so far and only lost two. The only draw back is when she looses the winner gets to fuck the shit out of her in front of a cheering crowd."
"She earns a lot of money defeating men in the underground fights. She better enjoy it while she can because she only has to loose once and her conqueror will claim her as his prize. Fucking her in the ring and keeping her as his slave."
"The fight had been even up to this point. She figured this would tip the scales but did not realise how. His cock hardened in her grip and he was filled with renewed vigour. And he beat the living crap out of her... and since she had got him hard he then claimed her."
