Adventure at college

I was chatting with Master Vincent just before my lecture and I just remembered that I've to meet my lecturer regarding one of my assignment. I told Master Vincent about it and he commanded me to unbutton my shirt before walking into his room. I was wearing shirt and jeans. I unbuttoned 2 of my button b4 walking into his room. My heart was beating fast. First time taking such a risk. Teasing my own lecturer. I was  sure what would happen. I walked calmly into my lecturers room. I saw him sitting at his desk neat the window. He was in his late 40s. As he is being sited his view was directly on my chest. I am very sure he noticed that my shirt was unbuttoned as I was approaching him. Upon reaching his table, I leaned over, still standing as i asked about my assignments. He was a bit nervous but he never talked anything about my shirt. He tried not to look but he was too tempted to see my cleavage and my bra which was clearly visible as I lean over. After about 10 minutes I said thank you, hold out my hand to him. He gave his hand and we shook. He had a very hard grip. And I left.

Later after my class at about 4.30pm, I came online and chatting with Master Vincent again. I was sitting at one of the empty classroom. Alone. He asked about my adventure in my lecturer's room. I told him all about it. He was impressed and he said he would reward me since it have been long time I had any real fun; no mastubation or sex. He ordered me to unzip my jeans and I started to finger myself. At this time I was sitting at the corner of the classroom and my action wasn't obvious. Then Master Vincent asked me to unbutton 2 of my button and unstrap my bra. I hesitated but he ORDERED me to do so. I did as told. Heart beating fast. Scared if someone would walk in. It's not my house, it's college. After fingering for some time I still haven't cum which made him pissed. He ordered me to stand up and bend over the table and finger my self. I was very scared as any one who would walk in could see what I was doing. No more hidden. Not very safe anymore. I followed. I did as told. I started to finger faster and faster. Heart beating fast. Still not cummed but already very wet. Suddenly I thought I heard someone walking in the corridor. I can be seen through the glass at the door. I quickly put my jeans button and hold my shirt as I rushed to the door. I saw no one. When I told Master Vincent about it he was very angry. He ORDERED me to unbutton all my button and take off my bra and button the bottom 3 of my shirt. I hesitated did as told. I was so scared. Heart pounding extremely fast. I bend over and start to finger again. After about 5 minutes I cum. I cum a lot. WOW! It was really nice cumming after such a long time. I thanked Master. He ordered me to go home without my bra and unbuttoned top 2. I protested but I couldn't do much. So I went home like that covering myself with my bag. Nipple was hard all the time.
