As long as the bull is CLEARLY vastly Alpha, compared to the cuck, its horny either way for the wife and the bull. Tbh, I could care less about the cuck hubby, but its probably true for them of course too, the loss of their role as a proper man in the relationship.
Ive seen so many guys let themselves go after they hit 40, no wonder the wife dries up on them. In one sense, the real scope is for younger bulls with more mature wives, especially good looking wives in their 50s, 60s, whose hubbies have not kept up with them. These wives get so horny, repressed lust, that in most circumstances theyd fuck or suck an Alpha of any age at the drop of a hat.
