In the steamy streets of Salvador, Bahia, local gay men gather for a secret, carnal ritual. The "piranha" is in session, and tonight, the catch is a massive, hung negao. The men, their bodies glistening with sweat and anticipation, take turns devouring the thick, uncut cock, their hands and mouths working in tandem to bring the beast to life. The air is thick with the scent of sex and the sounds of hungry moans as the piranha continues, each man eager to taste the negao's salty essence.
