I absolutely love the feeling of being too thick to enter on initial penetration! And I'm always up for the challenge. Having an extra big head makes it even more intense. I love working it in bit by bit and feeling her body react to the struggle. It's never really been a problem because I'm always careful about it. But one time, something bad did happen.
I was with a girl who was very tight who was also very good at controlling her vaginal muscles. She'd done a lot of kegels and liked to clamp down really hard while fucking, accentuating the struggle even more. Usually when something like that happens, I have to back off because it'll cause me to cum too quickly. But this time, I was really in the zone and felt like I could go as long as I wanted without cumming. So I forcefully crammed my thickness into her tightness over and over for quite a long time. It felt like I was fucking an ever-tightening vice! When we were done, I went to the bathroom and saw that my dick looked kind of strange. Usually, my penis is a few shades darker than the rest of my body, but this time it looked frighteningly pale and almost grayish in color and thinner, too. Like the life had been strangled out of it!
The next morning, I immediately felt like something wasn't right. About a half inch below the head of my cock, I could feel a hardened band of tissue underneath the skin wrapping all the way around the circumference. When it didn't go away after a few days, I went to the doctor. He said it could be some form of inflammation but was very surprised because he'd never felt something that hard inside the structure of a flaccid penis before. It was like a band of hard plastic that actually caused significant discomfort when I got an erection. He said to wait and see if it went away. It lasted for several months and I was really freaked out that I'd permanently damaged my penis! But it did eventually return to normal with no lingering complications, thank God.
I really learned a lesson with that one. The power of a tight pussy can be a dangerous thing when used recklessly!
