I looked around to see that everyone was looking. I was so self-continuos I had never dressed this way. I could feel the air on my pussy. Just then and there the vibrating butterfly started to move on my clitoris. I almost fell down to the ground. I had to get to the wall in order to support myself. The wall never seemed so far. When I finally got there I faced the wall and I wanted to grind my hips into the wall but the wall was covered with students lounging about. It kept on humming down there and I broke out in a cold sweat. How was I going to get to my class? I could barely walk. It finally turned off and I raced to the classroom before it began again. I had just sat down and it started again. I was sure everyone could hear it. But when a boy sat down next to me he didn't seem to hear the noise.

I remembered that my Master told me to cross my legs and when I did the feelings became even more profound. I gasped and then the boy next to me noticed how I was dressed and started to talk to me. Complementing me on my shirt and skirt. I couldn't answer him. Finally the instructor started to speak but I found I could not keep my mind on what he was saying. My private area was just ablaze. Finally it stopped. It cycled every 10 to 15 minutes and kept on buzzing for 5-10 minutes in-between.

Finally class was over and I found a cool spot on the grass and spread my legs out. The cool air that spread over my cunt felt great now. It caused some of the moisture to evaporate.

It was time for my science lab. I got into the classroom and sat in the back row in the farthest seat. I straddled the stool with a leg on each side. This caused my pussy and clit to come in direct contact with the seat of the chair and put pressure on them. I thought I was safe. People came into class. No one sat next to me. However when I got up from class there was a ring where my cunt had been. I leaned down and licked the seat clean and when I looked up I noticed my instructor looking at me strangely. He started to approach me and I ran out of there as fast as I could.

I remembered that my Master told me to go to the bathroom. I went into the bathroom and there were girls in front of the mirror. I quietly went into the stall and reached under my skirt and removed the battery pack and the butterfly. It was kind of stuck on me and when I pulled to remove it I just got hotter because it pulled on my sensitive clitoris.

I finally got it off and pushed it into my knapsack. I reached in and removed the package. I unwrapped it and found a human size dildo in there. I tried to insert it but it wouldn't go in all the way the way I was standing. The stall door opened and there stood my instructor and he said you need some help. I was mortified. I couldn't look at him. He instructed me to come out of the stall and bend over the sink. I could see all the girls were gone. He told me he locked the door. He sawed his fingers into me and spread my lips and in one shove he implanted the dildo into my pussy. It was huge and when he shoved it in I moved forwards against the sink and started to hump it. He said no, none of that and he unzipped his pants and told me to thank him for his help.

I put his penis into my mouth and started to suck it until he came in a spurt of hot liquid, which went down my throat.

He let me go and I got up and left the bathroom. I went to the bus stop and paid my fare and got on. The bus ride was at least 1 hour with all the stops. I sat down and it pushed the dildo further into me. With every bump it would cause the dildo to move and soon I wanted to come but if I did I knew my Master and Mistress would be furious. So I just kept it on edge.
