"Totally naked, very dark areolas and prominent nipples," Williams continued, critiquing the clip. "The guy is built like a 13-year-old boy. Well, my upper arm is bigger than his thigh. Just saying."
"She was weak on the tip. And real weak on the hip. If you saw the sex tape, it's online, weak weak and weaker," she added. "And there were no condoms. Yep. Everyone's smashing!"
