Practical in Biology

The first time I taught Emma was 2 years ago. When I first saw her I thought she was something special, for she was tall (around 5'9") so had long legs to go. She had dark blonde hair that suited her face perfectly and a rocking figure, not too much and not too little. She was 15 at this time, and was mature for her age but still had a childish side. The first time I thought she may like me is when she had stayed behind for some help with her homework I had set ,(about 6 months after I had started teaching her) it was only me and her in the class, so I went and sat by her. Straight away I noticed her relax. "So, Emma, what seems to be the problem?" "Well" she said staring at me "I am a little confused here" pointing at the second question on the sheet "Okay, how are you confused?" I asked, seeing as it was well within her capabilities "How do you remember which name is for which part of the heart?" "There is a little poem for that..."

Should we perhaps move to your chair at your desk?" My chair was a big comfortable office chair that had no wheels at the bottoms, but lent back and you could adjust the height. Emma walked over to it and made the back lean back a bit and made it low. She then beckoned me over. Like I was being pulled by an invisible rope I followed her command and sat down, dick throbbing. "Emma, if someone.." She put her finger to my lips and whispered "I will lock the door and close the blinds." When she had done that she started walking back over to me and pulled off her shirt, revealing her perky C cup boobs and hard nipples. I lowered my hand onto my dick but she lifted it off and lowered her mouth onto it.
