it's the girl from the cover

 You order from an Escort service, muscle Date. It speacilizes in strong women, Fitness woman and female body builders.

 You can hardly believe your eyes when you notice that the escort you have ordered is none other than the girl on the cover of the broshure, a busty Body Builder with long red hair. She has amazing muscles and legs that could kill.

  "Come in, you are very welcome. ... I have been saving up for years for this and now have enough money for a full hour with you".

   She replies by suggesting a little wrestling fun before we get erotic - "the winner is decided when one of us is sitting on the other's face, got it?" - "Okay"

  The match begins - you carefully reach out to touch her fingers for a test of strength. She does the same. You lock hands on one side.

You reach out with the other hand too. She starts moving her other hand toward yours, but then suddenly pulls you in with the hand you were already holding.

 The tug makes you take one step toward her.

 You are now at a perfect position for a knee to the balls Wham! AAAAAAaaarrgh! That hit the mark. 

She follows it up with a fist punch to your face.

You are already light on your feet.

She leaps in the air and kicks you right in the chin. Zonk! OOOOoooofffff!

You fly onto your back, dazed.

She follows you down, and sits on your chest, smacking your face with open palms from the left Smack! then the right smack!, then from the left again Smack! then the right Smack!, then from the left again Smack! then the right Smack!, 

then from the left again Smack! then the right Smack!, then from the left again Smack! then the right Smack!

 You are now dizzy and faint, your lips are bleeding, your cheeks are burning sore. You are ready for the pin ...

 She moves her ass over your face and sits down, softly at first, then, when she knows your mouth and nose are buried between her butt cheeks, she presses her full weight down on your face. Ooof!

 You are totally beaten and stuck there!  It is humiliating but at the same time a big treat for you both.

 "Now kiss my ass, you loser" - you comply - "we are going to do this again, two more times - if I beat you the second time, I will sit on your head for an hour and you must lick me out good and well, and if I beat you a third time too, you must accept any punishment I chose for you. And if YOU win, you can have hours of sex with me, understood?" she asked - "yes"  you mumble, obligingly.

"Now are you ready for round two?" you knew that you stood no chance against her, but the very thought of being given the priviledge of adding to her winning streak by being a willing victim to pulverize turned you on immensely. "I'm ready"
