My opinion:
This is definitely a step in the right direction when it comes to Vixen Studio's more direct embrace of cuckold/NTR-like content, but for me it misses the mark, hard.
Among the few people I've spoken to about cuckolding and its appeal, there's not much cuck-value added to a piece of porn from plainly saying "Yeah, this woman also has a boyfriend". Sure that being the case does on some level make a video hotter, but cuckold porn gets really hot when there's an intentional cruelty directed at the cuck from either the women present or even the bull. I do not see this happening here.
What makes cuckolding scenes hot isn't JUST the fact that there's cuckolding or cheating happening on screen. Most of it (for me) is derived from using the cuck as a self-insert character. This is difficult to do when the video has a documentary-style tone, a lack of acted out cuckold/NTR narratives, and (what I expect to be) very little cuck involvement.
This feels like it's for people who like to WATCH cuckolding scenes, rather than men who WANT TO BE CUCKOLDED.
Personally, I don't really care if the people on screen are actually dating. I just like seeing the contrast of someone (the bull) experiencing the absolute peak of conventional male sexual achievement (having a MFF threesome with two hot girls who praise him) directly contrasted with a someone (the cuck) experiencing the peak of male sexual failure (watching a physically superior man have sex with your partner).
Maybe I have more of a fetish for being cheated on than I do a fetish for cuckolding. Whatever, this is all just my opinion.
