A few years ago my wife and I moved to Connecticut, just outside NYC, and became part of a social group of young married couples who were also new to the area.
Chuck was the dominant alpha of the group, and we learned that, as the group's alpha, Chuck had sex with any of the wives he desired, whenever he desired,
and it was very soon that my wife became one of his favorites.
When I got my first chance to see Chuck naked, what I did see was that he has the muscular body that you typically see on Greek statues of Hercules, except Chuck has a hairy chest and body, with a big thick cock rather than the skimpy dick and smooth body that you see on most Greek statues.
Regardless, clothed or naked, Chuck is a physically imposing alpha male.
Whenever Chuck came to the house for a 'visit', my wife and I would greet him at
the door, and as I submissively stood there, he would bend down, give her a deep tongue kiss, pick her up in a bridal carry, and carry her upstairs to our bedroom.
I don't think big Chuck could do anything that more effectively demonstrated to both my wife and me that he was the alpha and in charge.
I always enjoyed having 'sloppy seconds' after Chuck and my wife had sex. However, Chuck, with his big man cock, would so thoroughly stretch her out and
fill her pussy with a huge load of his cum, that 'floppy seconds' is probably a more accurate description.
The physical contrast between Chuck and me could not be more striking. Chuck
is 6'3", a muscular 240 lbs, with a broad hairy chest, and an 8" plus, thick cock, while I have a swimmer's build, 5'7", 150 lbs, smooth, with no body hair, and a not quite 5" slender dick.
