You can call it whatever you want---hardcore, porn, trash, erotica---but this paragraph is so over-the-top it is classic. YMMV:
Freed from its confinement, his Herculean cock bounced upwards at a forty-five degree angle, and Ann stepped away from him to gaze at his hardened desire. It was thickly webbed with blue veins, turning it into an angry looking, purple shaft of wanton delight. She could see it expand and contract slightly as his lust heated blood coursed through the mass, his mushroom shaped head glowing like a burning coal. His balls were swollen and hanging loosely beneath the base of his prick, the scrotum covered with his dark, course pubic hair.
