A nice surprise

I put a ad on Craigslist one time ,a guy answered it ,wanted my address then said he'd be right there.
About 20 minutes later he kicked on my door, he was a older man tall and slender,salt and pepper hair .
We introduced ourselves,his name was Steve,he said his wife can't take care of his needs anymore.
So lead him to my living room, told him to drop his pants and have a seat on the couch.
When he pulled down his pants ,he released his huge cock at least 11" long and standing straight up .
I ask him how long it was ,he said it was 10 - 12" on a good day, it was at least 2" wide.
He sat down and started stroking it as I got on my knees between his legs,he held it for me as I began licking the head of it as he moans and flexes the head of it and some pre cum ran out ,I began sucking it taking as much as I could in mouth as I fucked my mouth with it as he stopped stroking it and let me take over .
I sucked and stroked his big cock as it got harder and a little longer and thicker, pre cum kept running out of it,was tasting really good.
I licked and kissed the shaft of his cock as I made my way down to his balls and licked them then sucked each one a little before getting back to working on his cock .
I took his cock from my mouth and was looking at it as I stroked pre cum constantly running out of the big mushroom head and down the shaft and over my hand. .
I went back to sucking it ,as he got closer to cumming he put his hands on the back of my head, fucking my mouth faster .
When he started cumming I gagged at first there was so much but swallowed what I could and continued swallowing til he stopped spurting cum ,then I cleaned up any that got away with my tongue, then sucked some more til he pulled away.
After that he came over every week or two for a long time til he passed , he got developed Parkinson's but continued to come see me til he couldn't anymore.
But anytime he came over he was already hard when he got here, that was the biggest cock I had ever seen except in movies .
I enjoyed sucking it though while it lasted. .
