It's subtle, but it's there. The clip starts at 2.36, when she is in a bathroom stall talking about her desire to visit a glory hole to play with black bull cocks. At 2:45, she pulls out her tits to show how excited she is, fantasizing about back dicks. Then, with an evident displeasure reflected in her pursed lips for not being able to be with one of her bulls and a hint of sarcasm conveyed through her voice(and air-quotes probably), she said (2.59 to 3.04)"GUESS, I GOTTA GO BACK NOW AND CHEER ON MY SON"

I mean,  it's not like the porn movies, but there is a slight there. Here the son is a cuckold, more in the Japanese understanding of  NTR/Netorare. Where a cuckold is someone whose love interest or an important person is 'stolen' by another person. Here the mother clearly wanted to be with her bulls rather than spend any time with her son.   And now the mother has augmented her body so much to be a bbc bimbo and living the QOS lifestyle in a way  there is little room for a normal mother-son relationship.
 
There are a lot of woman like her out there. At first glance, they seem like the perfect housewife with a loving family and a stable job, but deep down, they are unfulfilled. And the only remedy for this is getting filled by a bull cock. And now that they can monetize it, we will see many more of them in public.
