That about sums it up. Watching porn (especially big black cocks in married white pussy) is a turn on for cuckolds or wanabees. Just like beautiful women with big round breasts, good looking pictures of erotica will entice both men and women. So, it is not unusual for the observer to crave the image that is attractive. If watching black on white cuckolding turns the white cuckold, it is not a stretch to imagine him loving black cock. If he progresses to sucking black cock either with the cuckoldress or not, who can blame him. If you love it, SUCK IT. No labels, please.
