Twice...
The first was a guy I hooked up with at his place. I was there to see and service his cock as I was going through a bi awakening in myself, and I was hoping to experience some nice big cock... at least bigger than my own!
He dropped his pants for me and I was a bit disappointed because he was no bigger than me soft. It was pretty unremarkable, but I got on my knees and took it into my mouth. I licked and sucked and was getting into working it. I began to feel it grow.
He grabbed ahold of my head and took charge and began to face fuck me. I noticed my jaw had to open wider and wider as his cock became hard and engorged. My mouth was stuffed with cock with each thrust. I began to feel myself want to gag as it went deep. I was having difficulty getting air and he finally released my head and let me gasp for breath!
I found myself staring at an big, plump erection dripping with my saliva. He was quite a grower! Definitely breaking the 7x5 inch marks. I put my hands on it and gazed at it with awe! I sure had fun playing with it that afternoon!
The second was a guy who I had no idea what he might be packing. I was actually "interviewing" in reply to an ad the guy had looking for a guy to clean his house naked! But he fessed up to me that his real desire was to play with my feet! Turns out he had a huge foot fetish.
Well, I let him start to massage my feet. I was sitting back on a sofa and he was on the floor in front of me. He told me he was starting to get hard so I asked him to see it. He pulled down his pants and his briefs had a HUGE bulge in them! He then released his dick from their restraint and out pops this massive dick that was only semi erect. It was already bigger than mine when hard. Long and THICK!
When he got fully hard it was the biggest cock I had ever seen! He claimed it was 9 inches... I didn't think it was quite THAT big, but definitely 8.5" and over 6" around! I had recently been engaging a guy who had a legit 7 x almost 6" girth erection (I had even measured it carefully with a ruler and tailor's tape), and this one was way bigger and filled my grasp fuller with its girth!
We both got fully naked and most of his time was spent rubbing his cock on my feet. He fucked them by putting my feet together and I just watched the show. He eventually shot his load and he came like a lawn sprinkler, showering my whole body with his cum!
Sad thing is, he neve wanted to get together with me again. I still crave to see a cock as big again!
