They get me super excited, particularly if they are huge and pleasing on the eye. Like nice visible head, low hanging big balls to go with, fit body, not overly hairy. Dear lord the mental games of seeing a huge softy and thinking "holy shit imagine how big/hard it gets" makes it super exciting.
I think I have this kink because when I was younger a friend and I were exploring, and showed each other our dicks and I was hard instantly before I even revealed mine, but he was soft at first when he showed his. I thought he was sporting a semi as I was a little bigger, expecting his semi to finish getting hard and be about the same as mine as we were close in size. Nope, dude was soft as could be and was as thick as me and nearly as big. Then it got hard and got thicker, and thicker, and longer, and I was like


Happy ending though (for me at least), last time I saw his, mine was bigger. Just back then, that first time, he was dramatically bigger. Been a fan of big softies ever since!
