He kept sneaking glances at my legs and pussy, but he looked a... if he was a naughty schoolboy doing something that he shouldn't. Even though he went to help other students with problems, he wouldn't come near me. Each time I asked him a question he stayed at the front and explained in great detail what I should be doing.At the end of the lesson he was gone before anyone else. I overheard a couple of the.

I held her clit moving up and down on it. She went crazy, I put three fingers inside of her while I continued to suck her clit in a fucking motion..
