When I was in college I had a dom/sub relationship with my ta. We were together after class one day and he had me blindfolded with my hands secured above my head in his office.
I was completely naked for him when there was a knock on the door.
I heard whispering and could instantly tell it was my professor! He had a really distinct voice. I heard him take steps right in front of me and he sat down in a chair close by.
My ta kept playing with me, as my professor watched keeping quiet. All I could hear from him was his breathing getting heavier.
My ta moved me so I was bent over his desk. His hand tight in my hair the other around my throat! My professor had the perfect view from the side.
I came so hard when I heard my professor cum. Thank God for the desk that was holding me up because my legs turned to jello! A few minutes later I heard the door open and close. As soon as my professor was gone my ta took the blindfold off and told me that he and my professor planned this whole thing!
Turns out I really like being watched! We ended up playing in front of my professor a few more times during that semester.
