Rope and clamps

You take some magnetic clamps and rope from the supply room, and walk back to your exam room where Katie is waiting, red in the face, and still with a dildo inside of her. You close the door and walk over to her.

"These magnetic clamps will restrain your hands, and they stick to the metal exam table," you tell her. "Can you spread your arms for me?"

Katie spread her arms and you stick the clamps down on the table over her wrists. You do the same to her legs. Katie is now spread-eagled, and at your mercy. You take the dildo out of her soaked pussy, and then get an idea. Making sure that Katie can't see you, you unbutton your coat and lower your pants without making a sound. You take out your very hard, 7-inch long cock. You tease her pussy lips with the tip, and she wiggles with pleasure. Finally, you slide it inside of her, taking her virginity.

"Oh! Dr. John, that hurts!" Katie says.

"I'm sorry, Katie," you apologize, slowly removing your dick.

"Wait, it's ok. If it's part of the exam, then I suppose it's ok."

You can't believe you are getting away with this. Katie has no idea what is going on. You slide your dick back in, gently thrusting in and out. Katie lets out several soft moans of pleasure.

"Katie, I'm going to release some fluid into your vagina to clean it. Is that alright with you?" You ask, on the verge of cumming.

"Yes, that's fine," Katie says.

Just in time. You release loads of cum into Katie's pussy, filling it completely. You have taken her virginity without her knowing.
