"You had better stop now, honey. I don't think it would be appropriate for me to come in your mouth. Maybe you should finish me off with your hand."
My beautiful daughter took her mouth off of my cock and smiled up at me. "Well, Dad, it wouldn't really be a blow job unless you came in my mouth, and it isn't like it would be my first time. I've sucked off at least ten guys."
"Well, if you really want me to," I said. Knowing that I was close and ready to come at any time, she sucked enthusiastically. Damn, she was good. I had never had such incredible head. She didn't bat an eye when I started shooting. The load had been simmering in my balls for three days and was enough for two men, yet she swallowed it with ease.
"That was great, Dad. You have the biggest cock I've ever sucked and you gave me the biggest load I've ever had. Yum-yum!"
I suppose I should explain how my daughter came to be on her knees sucking me off. Eighteen-year-old Carol had just finished her freshman year at a prestigious Ivy League school and was home on summer vacation. It cost me a fortune to send her to that school, but some of my investments had paid off so I could afford it. I wanted only the best for her.
I had divorced my bitch of a wife two years previously. She was impossible to live with after she became an alcoholic. The experience left my psyche so scarred that I avoided women like the plague. My sex life, consisting exclusively of voyeurism and masturbation, could best be described as unhealthy.
Shortly after Carol came home, I received a mail order I had placed for several porno tapes. I always broke in new tapes with lengthy masturbation sessions, so I loaded the tape into the VCR, stripped off my clothes, and stretched out on my bed. In Carol's absence, I had become very careless about closing my door. It was several inches ajar so that anyone passing by would see what I was doing. I don't know how I could have been so careless. Perhaps subconsciously I wanted to get caught.
I stroked the length of my greasy cock as I watched several men and women mate in some very imaginative ways. I had been at it for about twenty minutes when a voice from behind my right shoulder said, "Dad, do you want some help with that?" I believe I may have had a very brief out-of-body experience at that instant.
"Wow, look at them go at it," she said, as she pointed at the screen. "Now those people have the right idea. I sure would love to be in that pile with them."
I quickly covered myself with a pillow, but the harm had already been done. "Dad, you don't have to be ashamed of masturbating. Sometimes I get so horny I rub my pussy raw. I would be glad to lend a hand. You've done so much for me that the least I can do is help you get your rocks off."
If I hadn't been so unbearably horny, I would have sent her on her way and there would not be a story to tell, but my cock was doing my thinking for me. I didn't want to seem too eager and waited a couple of minutes before responding.
"I'm afraid you might be disgusted by it, honey," I said.
"No way, Dad. I've been jacking guys off since seventh grade. I love doing it. Please let me jack you off. It would be the biggest thrill of my life."
I never actually gave her verbal consent; I simply moved the pillow aside. She sat next to me on the bed. When her soft hand encircled my cock, electricity seemed to course through my body. It had been two years since my cock had been stroked by someone else's hand.
"This is really a beauty, Dad. I've never seen one this big except in porno. It is a shame that this thing is going to waste. You need to find a girlfriend to use this thing on. This fucker must be at least nine inches long. Wow! Now you just relax, watch the people fucking, and I'll do the rest. This is going to be fun for both of us."
It seemed like a dream that I would wake up from at any moment. Incest was for rednecks in trailer parks, not for well-educated, refined, successful men like myself. Yet I did nothing to stop her. My brain, filled with eighteen years of academic schooling, shut down and my cock took over. The evil one-eyed monster was doing all of my thinking for me. It was obvious that my daughter knew her way around a cock. Her stimulation of the ultra-sensitive band of nerves just behind the head caused my legs to jerk like frog legs in a frying pan. I nearly went over the edge when she lowered her head and dropped a mouthful of warm spit on my cock to lubricate it.
It was impossible to take in everything that was happening on the screen. A dozen people were involved in a variety of sex acts - gay, straight and everything in between. "You really have good taste in porn, Dad," Carol said. "That bitch with the strap-on is really hot. Did you know that I like girls, too?"
My daughter's shocking revelation was the straw that broke the camel's back and my cock became a fountain. I came so hard that a gob of jism landed on my cheek. "Wheee, that's it, Daddy, fire away!" She jacked me almost painfully hard. My cum-cannon fired a volley all over my chest and belly. It was an orgasm unlike any that I had produced with my own hand. My daughter's gleeful reaction made it all the more intense. She continued jacking me even after the fireworks ended.
"Damn, Daddy. I've never seen anything like that before. You should be making porno movies. You came like a fucking horse!"
Carol brought a towel from the bathroom and dried me. "I'll be glad to do you every day, Daddy. Even two or three times a day. As many as you need." As she dried my cock, it began to harden.
"My, my, what have we here? Daddy, you really are a lecher. It looks like I'm going to have to beat you off again."
She didn't touch my cock that time. Instead, she jacked me through the soft cloth. She giggled as the towel slid up and down my shaft. I managed to last five minutes or so, then the cum that had been left in my balls after my first orgasm shot into the towel.
After Carol left, I vowed that I would have no further sexual contact with her. I shuddered to think what might happen when my cock started thinking for me. I doubted my ability to resist her ample charms. However, my resolve only lasted a few days. As I lay on my bed masturbating, I remembered how good my daughter's hand had felt on my cock. Her playful demeanor had made it all seem so harmless. I went to her room with my hard-on bobbing in front of me. She was lying on the bed watching TV in a skimpy bra and panties. She smiled when she saw me.
"I was wondering how long you could hold out, Daddy. Come and let nurse Carol treat that swelling between your legs."
