"Show me. Put your hand in your pants and show me how wet you are." I reached into my jeans and wiped my swollen pussy lips and held up the wet evidence.
"Taste it." I sucked my finger of my own pussy juice. He never took his eyes off of me. He held his hard cock in his hands and pushed my head back down to it.
"I'm going to come and I want you to swallow every drop," he said. My mouth was so wet as his dick slide in and out of it; I kept my lips tight around it to keep a good grip to maximize his pleasure. He pulled and pushed my head with force to get his hard dick as far down my throat as possible. I had enough experience giving blowjobs that I knew how to pace myself and keep from choking. Then one final pulse of his cock and I knew he was cumming. He held my head right to his crotch as he unloaded, his hips bucking off the chair and into my face. His dick was so far down my throat his cum shot right down, I barely even tasted it. When he let go of my head I kept sucking, and work his dick until all the cum was gone and he had gone limp between my lips. When I raised my head he smoothed my hair down with both hands.
"How does an 18 year old girl know how to give such good head?" He asked smiling.
"I had to keep my grades up and I've never been very book smart," I answered wiping the saliva off the corners of my mouth. He pushed back his chair and stood up. I stayed kneeled on the floor. He closed up his pants and buckled his belt. He opened the top side drawer of his desk and took out a credit card.
"Don't go too wild," he said and placed it on the desk. He turned toward the hidden door he came from earlier, "Close the door as you leave sweetheart." he pushed the wood frame of the bookself and the door swung open and he disappeared behind it. I got up, straightened my pants put the black American Express card in my purse and closed the door behind me as I left.
