A man from the Brazilian city of São José do Rio Preto has accused his wife of trying to kill him by stuffing a poisonous substance into her vagina, and then asking him to perform oral sex on her.

The unidentified 43-year-old told police he was luckily deterred at the last minute by a "strong toxic smell" emanating from his spouse's private parts.

The man rushed to the hospital to have his stomach pumped, but doctors were unable to find any toxic substances in his system.

According to Argentina's La Razón, the woman later confessed to the crime and was found to have enough poison inside of her to kill both her husband and herself.

The wife reportedly requested a divorce from her husband prior to the incident in question.
