First of all, I seek amateur porn. Yes, the camera work often lacks clarity and good angles. But, the realness and spontaneity more than compensate for the amateur camera work. Other favorite cuck themes within the amateur category:
Husband does some talking with wife, but does not overdo it. Can be loving encouragement for her or aggressive talk to the bulls, like telling them to fuck her silly. Husband talking can ruin the video, or enhance it. A delicate balance.
Seeing her face and body, and hearing her moans. Too many videos concentrate on the crotch, which is ok to show that she is taking a bull or bulls in her pussy or ass, or both. But once I know how the bulls are fucking or eating her, I want to see the look of pleasure on her face and the uncontrollable movements of her body. I really get excited by that. Big turn off: music or television in the background.
I want to see her wedding ring.
One bull with her is fine, but I get really turned on by multiple men having sex with her. Can be two bulls or a gang.
Bull(s) with mature, conservative looking wife (MILF) is a turn on. Love seeing an average looking mature woman that no one would suspect in the cuckold life enjoying uninhibited sex with other men behind closed doors.
Love interracial cuckold. Interracial cuckold gang bang is a real turn on.
Husband participation is good, even if only to hold her as a show of love and support. The love and support is important even if he tells the bull(s) to use her like a slut.
I do like bisexual cuckold where husband sucks, takes anal, and does cleanup for wife and bulls. Better if wife orders him to do these things.
