Karens third orgasm was so intense that her sudden cry brought another member of the faculty into her office to see what was wrong. It also caused me to ejaculate, powerfully and repeatedly, which I did into the towel. "Are you okay, Karen?" He asked. Apparently the intruder couldn hear the wet, smacking sounds coming from her pussy, or the squish as my cum splashed into my towel. If he stayed very long, I knew he would eventually smell everything, and I silently urged her to get rid of him.  
  Karen was still trembling and shaking. "Just some gas pains or something, Mike. Ill probably go to the restroom in a minute. Thanks for checking on me." Mike left after expressing his concern once more. I had been holding my breath, and as he walked from the room I released it directly onto her crotch, She jumped and made another little cry as her pussy suddenly became chilled.  
   
  Under Karens dress the aroma of her pussy and my cum was so strong that I was afraid that Mike - or anyone else who came in - would smell it immediately! As I pulled my head away from Karens crotch, she pressed the towel hard against herself, soaking up her abundant, sweet-tasting juice. I folded my cum into the other towel, then used the outside of the towel to wipe Karens juices from my face.  
  I carefully redressed myself as best I could under Karens desk, then waited for her to signal me that the coast was clear. With the towel still clamped between her thighs, Karen suddenly rolled away from her desk and whispered, "Okay, Bill! Get up now!"  
  I scrambled out, stood up. and rearranged my clothing. Karen giggled and pulled a tissue from her purse. She wiped my face, removing a spot of juice I had missed. Just as she finished Harry walked in. "Oh, there you are Bill! Hey, I have a question. Do you have a minute? Are you done with Karen?"
