Ejaculation after climax after orgasm and over again!

I have been seeing this gentleman for about ten months now. He comes to me from about an hour away and always calls when he sees he is going to have time to come for a visit and a blow job. When we began this relationship, he would sit or stand and offer me his crotch and his flaccid penis. His foreskin would be loosely covering his cock head with his fat, limp shaft settled between his large, low hangers. I usually begin by feeling his penis in my hand. He has a really beautiful penis with a large but very loose foreskin, a thick shaft and a huge shiny mushroom cock head. He begins to grow a little as soon as I touch him and his big cock head begins to expand out of his loose foreskin. I then usually begin to play with his cock head, opening his huge piss slit and pressing it back . Then I can wait no longer! I have to take him into my mouth. He usually groans and I moan as well. Then I begin to suck, lick and use my lips, mouth and tongue to tease him to a full erection. After a few minutes, he usually asks me to make it last as long as I can. I, mouth full of hard penis, mumble that I will - heck, I love doing it just as much as he enjoys what I do. We go on and on like this for up to half an hour and finally we seem to jointly decide that it is time for the climax and his orgasm. He tenses and squeezes my shoulders and growls as his penis explodes in my mouth. His climax and orgasm lasts a minute or two and I take several more moments sucking all the semen out of him and licking and caressing his big firm penis from base to tip. Well, yesterday was a different day. Because of various problems and interferences we had been unable to meet for more than two weeks. So, I made up my mind that this time was gonna be extra special. I set up one cam to over look the whole experience and held the other in my hand. He sat on the stool and this time I couldn't wait to get my mouth on him. I sucked his penis, with the foreskin still sheathing his cock head, into my mouth. I began to suck him the way I always like to, in long, quick strokes, sucking my way to the base of his penis and then releasing him back until his cock tip is between my lips. I sucked his shaft down and back out again, many more times. There was no world except my mouth and his penis. He never begged me to make it last, but I know what he wants and I used every trick I know with my mouth, lips, tongue and throat to excite him to the fullest extent, just stopping short of bringing him to climax. Then after what wasn't long enough I can feel his hands tight on my shoulders and for the first time ever he is pressing me against his crotch. Then he grabs my head and pushes me down against his penis so that my lower lip is against his ball sac and his penis is down my throat. He then starts pistoning my face up and down on his penis, again and again. Rough and hard, he uses my mouth as if it were a pussy and I can feel his penis grow and grow and begin to jerk and spasm. My mouth and throat are full of his cock and now I can begin to taste his semen. The taste grows as he pumps in and out of my mouth while his hands hold my head down on his, oh, so hard penis. We continue like this for an impossible time, much longer than he has ever ejaculated before. And he keeps on ejaculating, more fresh semen and more and more and I keep tasting him (you know that taste, kind of "round", a little alkaline, not like any other taste there is) and I swallow and swallow. More cum and more cum - much more than we have ever shared at any time in all our times together. Finally, I pull my head back and gasp something like, "Oh my God!" His penis is still jerking and I slam my face back onto his crotch, his penis continuing to jerk and squirt semen into my mouth. I realize during these moments that I have never really tasted his semen quite this much...stronger and more unique tasting... After a few more minutes, he asks, "Can you take some more?" Of course I can! He pushes me back on the sofa and stands with his feet on either side of my thighs on the seat cushion. He thrusts his penis back into my mouth and begins to face fuck me with my head bent backwards against the top of the sofa cushion. I can tell he is still ejaculating and he is shouting, "Oh! Oh! Oh!" Then he steps off the sofa and moves quickly back onto the stool. I follow and take his penis back into my mouth again...I marvel that he has cum at least three times already. I begin to suck him...not in the smooth gentle way I usually do, but pistoning up and down on his hard penis, feeling his big, fat cock head in the back of my throat...I am thinking, for the first time in all the time I have been servicing this man, I may gag on this much cock. But I concentrate on how good his slick, smooth, semen covered penis feels in my mouth and throat and I just keep on sucking. Now he has my head in both his hands and he is pressing his penis hard against the back of my throat and I can feel and taste once more another ejaculation of his semen. His huge shaft is jerking and slamming into my throat and his last load of hot, white semen is exploding into my mouth and throat. It takes us both a few minutes to get back down to earth. He smiles a little shyly at me and winks! I can only say, "What a trip!" Want to know what is the most exciting thing about this? This guy's birthday is Sunday next and he will be 81! No joke! I have loaded many pix and vids of him on this site. But the vids of this blog are too long to fit on here. I will eventually upload them onto another site. Please check with me and I will tell you where to look. It will probably take a couple of weeks for them to be available. Or, you can come and visit me and I will show them to you in person. And we might be able to make another video.
