They start to your mouth.

"The little bitch is dripping," Richards says, pulling his fingers out of your pussy. "You love this, don't you, slut. Makes me wonder why you refused me earlier. Well, you're going to do it now. Put the bitch on her knees," he tells your professor, who forces you down in front of your employer.

Richards unzips his pants and pulls his cock free and you gasp with shock. He's huge, long and thick, and bigger than anyone you've ever seen outside a porn movie. He smiles cruelly at you and pulls your head towards him. You clamp your mouth shut and shake your head, pleading silently with your eyes. He rubs his swollen meat across your face, smearing precum on you.

"Open wide, slut. You're going to take it one way or another, and we already know you love to suck cock, so why fight it. Get that sweet little mouth open."

Your resist, even though the heat smoldering in your pussy wants to obey, wants you to take this massive cock in your mouth, wants to see if you are up to the challenge of swallowing it. But you fight the urge because a part of you knows that if you surrender now there will be no going back. No return to the good girl you believe you are, that you've always tried to be.

"The bitch won't open up," Richards complains. "I'll get her little suck mouth open." He steps away from you and picks up something from a table. He comes back and seizes your breast, squeezing it as he looks in your face, then pinches a clamp onto the nipple. You gasp in shock and pain at the feel of it, but can't help the flood of pleasure that flows through your pussy. He clamps your other nipple and the pain and pleasure redouble. You're gasping desperately now, your breathing ragged, your mouth open. Your professor holds your hair and pulls your head back and Richards thrusts his cock into your mouth, filling it with his hot meat. Despite yourself you start to suck and lick at him, suddenly eager to please him.

"That's a good little bitch," he groans. "Take those cuffs off her, I want her hands free so she can use them when she sucks me." Your professor unlocks the cuffs, letting your hands free. He holds your hair to keep you in place as your mouth is **** by the thick monster cock. You grab the shaft with both hands, stroking him. Maybe if you can make him come they'll let you go, you think for a moment, but another part of your mind tells you they'll never let you go until they've violated every part of your body.

****, thinking this might be your last chance of escape, you simultaneously drive an elbow back into what you hope is your professor's groin, and punch Richards in the balls. You miss making solid contact with him, but he gives and grunt and staggers back. Your professor gasps and lets go of your hair, and you grab the opportunity to scramble to your feet and run out the door of the room.

Stumbling frantically into the hallway, you feel disoriented, not sure which way to run.
