Classic Diva Manor
Mistress Debra quickly jumps to her feet, pushes you backwards onto her desk and jumps on top of you.
"Now listen up slave. You'd better have staying power because I'm going to be humping your cock for a looooong time. Your job is to lie back on this desk and keep that thing hard for me. I'm gonna slide my wet pussy onto to your boner and then ride it like crazy while my boobs bounce up and down and maybe even out of my bra.
Now lets see if you can handle a woman. I'm not going to stop until I cum. You of course are NOT allowed to cum. Here we go!"
"Oh, oh, ooooh, arrrr, arrrrh, oooohhhh, that feels so good!"
[You have to endure 2 whole minutes of fast strokes (without stopping), at which point Mistress Debra cums and you can continue. If you cum, you are not worthy of being a slave in the manor and must leave. Do not continue]
