This is sexpert Auntie Angel, who's real name is Denise Walker. According to her, women have employed the use of her fellatio techniques to give men blow jobs that give them heart attacks. The 43 year old woman says that her "Death Technique" is killer good.

She shows off her technique in this video using a grapefruit as a prop. Video is NSFW.

She makes a weird nose in the video and it apparently is something a man will never forget until the day he dies. Angel says that a man she was dating gave her the idea to use a grapefruit. When she tried it on him he said, “Oh my god, it seems like you’re giving me fellatio and sex at the same time.”

Check out her interview with Vice here. Angel has reportedly taught more than 50,000 people over the past 10 years. She's also a big promoter of safe sex.
