Frank Marshall Davis wrote under a pseudonym the book, “Sexual Rebel: black”.
he described enjoying 3-way sexual encounters and loitering in Honolulu public parks in order to meet and seduce visiting white tourist couples wanting to be cuckolded by a large black man.
Frank Marshall Davis was a strange-looking leftist pervert pornographer who was on a FBI list of people to be automatically arrested in case of outbreak of War.
There's a market for that??

It seems likely that FMD used 3 generations of Dunhams as receptacles.
