A Brazilian man has claimed his wife attempted to kill him by putting poison into her vagina and inviting him to drink from the furry cup.

The unnamed husband, from São José do Rio Preto, in the state of São Paulo, told cops he and his missus had an argument. She then allegedly doused her privates with a "toxic substance" before suggesting her other half eat at the Y.

Luckily for the intended victim, he smelt something fishy before diving in, and thwarted the cunning cunnilingual plan.

Given the "unusual" nature of the case, officer Walter Colacino Júnior, of Rio Preto's 4th Police District, has decided to probe deeper into the matter before taking any action. ®
