As young as 12 I was completely full of confidence and dirty thoughts. I knew my looks would drive men wild, older men especially. I knew that these men would want to experience my tight, young body and if it was offered, they couldnt resist me. Innocent looking but sexually aware, I would have no problem bringing them to their knees and begging to taste how sweet I was. He was a teaching assistant in my English lesson, known as Mr Curtis. He was a little taller than me with blue eyes and stubble, looking a little nervous as he addressed the class. An average looking, dark haired guy being introduced into our boring lesson, I started to fantasize about ways I could ruin him. I kept intense eye contact and after a while noticed that his eyes were fixed on every inch of my teenage body. I was now 14, 5'4 with dark brown hair and a great bust that most women would be proud of. I carried my figure in a tight fitting uniform for moment such as this, knowing that my top three buttons were always conveniently undone and that my shirt was tight around mt breasts. I knew he wanted to roll down my knee high socks and slide his hands slowly up my little black skirt. The boys in my year bored me, I wasnt interested in what they thought they could offer me, I craved the attention of a strong, experienced man. After lesson I waited near the stairs at the bottom of the hall. I watched as he was complimented on how professional he had been during the morning. Only I knew what was running through his mind. As he walked down the hall I knew that he had noticed me standing there. Starting a conversation, I casually and open endedly asked if we had met before? To this, his response was that he would have remembered a face like mine I we had. As he continued to walk past me, I caught him looking and smiling. I turned to walk up the stairs, "I'll see you in class then Sir!" I knew he was watching me so as I took each step I inched up my skirt knowing that he would see a glimpse of my tight white knickers. The following weeks, I would flirt, and when no one was around, he would flirt a little back. I sat on my own at the back of the class, waiting for my chance to raise my hand and get his attention. Eventually he came to offer his assistance. He sat next to me and cautiously I let my kknee touch his. He looked up at me but didnt move away, I wanted more. I slighly dropped my pen and made it seem like I had been very clumsy. He offered to go around and pick it up for me. As he did I smiled and watched him lean down under the table, I opened my legs to expose my lacey knickers. He didnt get up straight away so I knew he was enjoying the show. I quickly pulled them to one side to reveal my tight pink pussy, I rubbed it, getting wetat the thought of him watching me. Emerging, he looked a little flustered and as he sat back next to me I noticed his hard cock through his trousers. "You are a naughty girl arent you?" he whispered as he adjusted his cock so as no one would see. "I want to play" I said, touching his thigh. He was obviously very cautious and replied that he couldnt, "Are you sure?" grabbing his hand and guiding it to my pussy over my wet knickers. He continued to touch but kept pointing to the book in case anyone was looking. I followed his lead, putting my elbow onto the desk, with me facing him and no one else. I felt him fumbling around, eventually pulling my knickers to the side and sliding his finger in. I noticed his jaw clenched and I closed my eyes, trying so hard to moan to not attract any unwanted attention. By this time he has slid another finger deep inside me, feeling so good and close to cumming. He was watching intently, waiting for me to crumble in pleasure. Just at that point, lesson was over and the class stood to get ready to leave, Mr Curtis got up just as quickly. At that moment any body could have caught us and I wouldnt have given a damn, I was so horny. As he left he turned to give me a dirty smile. I often replayed those few minutes over in my head after I didnt see him after this. The thought would always get me going and end in me playing with myself under that same desk. I still think about him to this day. ; )
