I did exactly the same with my wife few years ago, but more didn't know about it. It was a truly surprise for her. It was absolutely amazing, her pussy never felt nothing so big. 1 min and she cum lol
I'm average btw
I'm average too, but are always bigger ones to compare. If my wife has sex with someone else I want he was bigger. Her dildos are bigger of course, and she can compare mine with bigger ones. My wife doesn't think I'm small, in fact she says I'm more than sufficient, but she knows are bigger ones...
