That’s a big dick, obviously, but I believe yours is a silly notion.
For one thing, a lot of men (maybe even most men) who develop an interest in this are older, and come to that place after fathering children/raising families. I really believe prime territory for couples to find their way to cuckoldry/sharing and decide to explore is mid-forties and well beyond.
I slip in the roll and don't even show past the end while rock hard. Meanwhile my good buddy tributing my wife can't even fit it over his cock head and is much longer compared side to side
At least he is jealous that mine gets to fuck my wife =)
