In parts one, two and three, I told you how my wealthy father used bribery to keep me a virgin until my eighteenth birthday. On that happy day, he handed me the keys to an expensive imported car and a letter of acceptance from the finest university in the country. Both bribes had cost him dearly. After my fabulous birthday party, Daddy called me to his study where I learned his true motive for wanting me to be a virgin. He wanted my cherry pie all to himself!
My training began immediately. Each session began with a "training tape" that Daddy had made with my mother, whom he had divorced years before because of her alcoholism. The first tape featured nothing but hand jobs. I watched in awe as Mom jacked off Daddy and her own brother time after time. Then Daddy wrapped my hand around his enormous shaft and told me to put what I had learned to good use. I used my strong tennis arm to jack him until cum went flying everywhere. That was the biggest thrill of my life.
A few days later I was given a more advanced lesson. I coaxed Daddy's love juice out of his cock with my lips. He made a woman out of me the third time around. He brought me to orgasm with his strong tongue and plucked my cherry while I was in ecstasy. The pleasure of the orgasm was so intense that it smothered the pain. After he had fucked me, he whispered that only one lesson remained. For the life of me, I couldn't imagine what it was. He had the use of my hands, mouth and cunt; what else was there?
After a hot, soapy bath I joined my father in his study, the very room where my seduction had begun. "I can't wait for some good sucking and fucking, Daddy. Why do you make me wait for it? Bad Daddy! I want your big cock in me every day, morning, noon and night."
I sat beside him, pushed his hand away from his cock, and took possession of it myself. "Would Daddy like me to jack him off?" I asked. "There's something I want you to see."
"Another training tape? But I thought my training was complete. At least I know the basics."
"Not quite, Pumpkin. A woman isn't truly a woman until she's invited a man in through the back door." I still wasn't sure what he meant. He pressed the button on his remote control and my mother's smiling face appeared on the screen. The camera, which was operated by her own brother, panned down her body, until her lovely ass came into view. I was horrified to see Daddy's enormous poker stuffed squarely in her rump!
"OH, MY GOD! OH, NO, DADDY, PLEASE! YOUR BIG THING WOULD NEVER FIT IN THAT TINY HOLE. YOU WOULD SPLIT ME IN HALF!" For the first time, I felt fear.
"Take it easy, baby. You know that I wouldn't do anything to hurt you. I have some gadgets that will break you in painlessly." He opened a polished wooden box and showed me a set of six tapered rubber probes. The ends were narrow and rounded. They gradually increased in size until they reached their thickest point some three inches from the tip. Past that was a smaller neck and then a round base with a ring set in it. "What are those things, Daddy?"
