But I become picky, It's real hard to me enjoy a porn. In one hand, the massive cuckold pornography portray the cuck as a loser. Personally, I think that cucks are wrongly stereotyped. You can be self-confidant, smart and... Play with your sexual weakness. Other hand, the swing/sharing porn hides a typical situation when 1 or more guys are sharing your girls: the sexual potency. Usually one guy is better than other so comes implicit (never forget this word) that the girl prefer one of them, while the cuck try to please her in another ways (non-conventional sex).
reddit has a lot of threads where guys are looking for this kind of porn, while others are talking about his 1st sharing experience that ends up turning in a cuckold experience.
so, I think the perfect scenario is something like: when the hierarchy don't exist at first, young swingers are only looking for funny and this experience turns into a cuck experience. You will be humiliated not for words, but for attitudes. Highly moans, orgasms, etc. You stay curiosily excited while your girl sit on your face to you suck her while the Bull is streching her at the same time ... And It's so good to her that she don't mind too much to your pleasure, do a bj only because she loves you
