Was having a lesson of Anatomy, and our sexy professor was full of enthusiasm, hehe seemed it was his favourite part of that about difference in sexes, he was walking while he was explaining all the material to the pupils, once he stopped next to me, I could see that BIG difference at the level of my eyes, his cock was so hard inside his pants, he could feel my staring eyes and he rushed to take his place at the desk again. But that moment was enough for me to start be excited and I started to touch myself. His presence made me cum so quickly and wet.
