I tried to stay quiet but she was too damn good as she worked my throbbingshaft down her throat to the hilt and buried her nose in my pubic hairs. She...egan to bob her head, working her full lips and undulating tongue over allnine inches of my thick cock. After only a couple of minutes I moaned, "Mom,I'm going to ..."Right as I was about to cum, I saw her head get pulled back. Tyrone had herby the hair. I shot three or four loads into her face. She looked disgusted.There was cum dripping down. Am I right?”She swallowed hard, this pretty young student, and then said with a marked lack of eloquence, “Fuck you Mister.” Despite the obvious attitude she made no move to walk away.“Now if I had said those words to you little girl, then maybe they would have a more literal intent underpinning them.Once more she swallowed hard.“I bet if I asked you to remove your sweater I would see the marks right? Red and raised, the welts from a whip.”Her eyes widened beautifully as the nail was hammered. Every answer she got enabled Tabs to understand more about the part that chemistry played in the life of any industrial nation. That industry might only be the preparation of hides by tanning, but dying also played a part in all the cloth industries.She learned about chemicals that helped intensify the colour of a dye, or getting it to be fixed permanently in a fabric (originally using alum as a mordant), so that washing the fabric would not remove part of the dye. All the early dyes were from. An image of her gorgeous ass causes an involuntary quickening. Back and forth. I lean back against the wall and for a moment my eyes half open. My heart almost stops and I freeze. She is standing in the doorway. Her long dark mane is tousled, half over her face and a strand is in her mouth. She is biting her lip, her firm tits heaving. I feel embarrassed. Horrified to have been caught I am a teenager again, suddenly ashamed, but in the same instant I see her right hand cupping and squeezing her.
