I...don't think this is for a bloat, if so, some one really shaped the breast wrong for a moob. Perhaps the Matriarch is a Queen Bloat in effect, I mean, with a chest pepis like he has, ugly ol' Kevin likely needs quite a bit of cusion for the pushin' if ya catch my drift.
Now in a less silly manner
The breasts/nipples are to 'perky' for them to be that of the bloat from what I've seen, they aren't sagging with the nipples 'stretched' away from the center of the chest but rather seem firmly centered in the breast, implying said breast applies to a female as opposed to a male. But that's just how it looks to me.
