I love sticking things in guys (and gals for that matter). One of the most daunting things a guy can see is a steel rod sticking out of the end of his cock. It's a sight I love to see and make happen but I can't imagine what it must feel like. I've been told:

It's like getting fucked from the inside.
It stings a bit.
It hurts.
It feels great and I think I am going to cum.
Sorry, Mistress. I came.
An orgasm after sounding is the best.

For those that have experienced this, how did it feel? Is it on your "yes" list or your "hard limits" list.
