I have taken cock up my ass for 44 years; I have been a cuckold since our honeymoon, 36 years ago. Photo 1 shows my cock and balls. The balls may look big, but only a few drops come out when I jerk it off. Photo 2 is the cock of one of my wife's 30 studs; it is one of the "smaller" ones. Photo 3 is another stud demonstrating how much cum he shoots into my wife. From what my wife tells me, this is a typical bull load for her. I don't think there is any doubt as to why my wife prefers other cocks to fuck her and to plant babies in her belly. If you want to see why my wife is a favorite "semen depository," see her photos in my profile.
A man has not lived until he watches another man fuck his wife!
