Gregory S., 10/04/2021: 
This perfect pair of playmates once again present professional potential, and their affection is again abundantly apparent.
We see more than enough of Kai to sustain his claim to ultimate perfection, as sunlight glistens off toned muscles, and the tight shorts often reveal ample definition.
Nobody makes boxer briefs look quite so "barely there" as Mark!
In short (so to speak), there is more than enough on offer here to make this an absolutely recommended addition for all fans of Mark and Kai.
