Breastplate

A Breastplate is a decorative tattoo across the chest usually below the neck and above the bosom centered on the sternum but not always. Like some breastplates of the middle ages had insignias like winged eagles or family crests. Many breastplate tattoos look symmetrical but symmetry is not necessary.
Look at Porn Star Misti Dawn's breastplate... it really accents her cleavage.

Where'd you get that breastplate and sleave? Very nice artwork.

Breastplate Boomer

Not just any old boomer, the boomer of all boomers. Breastplate Boomer quickly rose as a postwar icon after his service in the Skaraana vs Humanity war of 2021.
Who the hell is that old boomer?!
That's Breastplate Boomer, the messoah and grandfather of the prodigal son who's face is glazed in cum.
