Studded paddle

You watch as Jenny reaches into the box and pulls out a huge red leather paddle with sharp looking metal silver studs all over one side.

Doe slaps you hard, with her hand, on your right cheek, and you fall to the ground.

 "Bend over my desk, **** bitch!" Jenny jeers.

  You find it hard to stand up as your hands are still cuffed behind your back, and they laugh at this mockingly. Eventually, you manage to settle into a position bending over the desk, but your face and body feel uncomfortable against its cold wooden surface.

 "Let's show him what happens to stupid little boys who get ideas of their own, shall we?" Doe laughs, as she brings the paddle down hard on your ass. The studs aren't as sharp as they looked but they still hurt. You bite your lip to stop yourself shouting out as Jenny has her turn at spanking you hard with the paddle. Then, when Doe has her turn, she makes contact in exactly the same place.

 "Ow" you whisper to yourself, hoping they hadn't heard.

  They had.

  "Ah! Did that hurt your bottom?", Doe taunts in a baby voice, "That's too bad isn't it." They then proceed to take turns spanking you for the next 15 minuites, and you find yourself getting increasingly turned on by the pain and by their taunting and laughing at your every reaction. By the end of this, you have a throbbing pain in your ass, and even just from Jenny running her finger down your left cheek, every muscle in your body wants to scream out, but you don't. 

 "One more!" Doe taunts, and she brings the paddle down with such a **** that you're sure it's going to snap. 

 "aaaaah!" you yelp as your legs buckle and you fall to the ground.

 "Look. The little pussy has had enough already." Jenny says looking down at you maliciously, "but the fun has only just begun..."
