Japanese grandmother hilariously mistakes synthetic sex toys for socks

A Japanese man was horrified after his grandmother appeared to mistake his sex toys for socks.

The 21-year-old filmed himself finding the pensioner in her dressing gown sitting on the edge of her bed in Tokyo, Japan, on July 5.

She had a pair of silicone vaginas normally used for male masturbation slipped over her feet to keep them warm.

The bachelor, who would not be identified, then told his grandmother off before explaining what they are actually used for.

''At 21, I never thought I’d be taking away onaholes from my grandmother’s feet,'' he says.

The man then removed the 'socks' from his grandmother and vowed never to use them again.

Onaholes are a type of synthetic vagina sex toy available in the Far East country.
