When I was 18 I needed to go to my Marine Biology teacher to ask for some extrs credit to raise my grade up. You have to understand that my teacher was about 6 foot, nice legs, an ass to kill for and massive tits. I had always made it known to her that I thought she was gorgeous, but she really just always ignored me. But I was getting my extra credit when she said that she was getting hot, so she took off her sweater revealing her enormous tits through her shirt. When I saw this, I figured that she just did it to tease me. After talking to he for a while she said that she had more stuff for me to do in the side room. She said to go in there and she would be right in. I went in and looked around to see what was in there, while to my surprise she was locking the doors. When she came in, she asked if I minded her taking her shirt off because she was hot. Even though that this gave me mixed signals I agreed. She then pulled her shirt over her head revealing to me her fine ass tits. But because she was a teacher I didn't know what to do. She then asked me to grab a box and hand it to her: I did so. When I turned back around to hand the box to her, my elbow nudged her tit. She then grabbed my hand and told me that if I was going to be shy she was just going to have to find another man. This turned me on and gave me an instant hard on. I then leaned over and kissed and sucked her tits. She started to moan and grabbed the crotch of my pants. She then proceeded to take off my clothes as I undressed her. When she pulled my boxers down my dick stood out about 8 inches. She then knelt down and proceeded to give me a wonderful blow job. I couldn't hold it too much longer because I had gotton so exited sucking her tits. But I couldn't hold it and I pulled out of her mouth and shot the biggest load of cum on her face. She then got disappointed and said that she wanted me to fuck her up the ass. As soon as she told me this I instantly got hard again. She then looked at me and asked if I wanted to . Right then I bent her over a little table back there and aimed my dick toward her tight ass. It took me a couple seconds to get it in but when I did it was heaven. After fucking her in her ass for about 4 minutes I jizzed in her ass.
